Combo disappoints in metastatic, castration-resistant prostate cancer
In a phase 1/2 study, adding saracatinib to docetaxel increased toxicity without improving progression-free or overall survival.
“Although we could safely combine the Src kinase inhibitor saracatinib with docetaxel, it did not show any improvement in outcomes, when compared with docetaxel plus placebo. We therefore do not recommend proceeding to a phase 3 trial,” said investigator Robert J. Jones, MD, PhD, of the Institute of Cancer Sciences at the University of Glasgow, Scotland.
Dr. Jones presented the phase 1/2 trial results at the 2021 Genitourinary Cancers Symposium (Abstract 107).
He explained that saracatinib targets Src family members, and Src activity is increased during the acquisition of castration resistance and during taxane resistance. Dr. Jones and colleagues therefore theorized that saracatinib could be beneficial for patients with mCRPC.
The team tested their theory with the phase 1/2 trial, enrolling patients with mCRPC who had not previously received taxanes or radionucleotides. Dr. Jones reported results for 10 patients in the phase 1 portion of the trial and 140 patients in the phase 2 portion.
In phase 1, patients received saracatinib at 50 mg, 125 mg, or 175 mg daily plus docetaxel at 75 mg/m2.
There were no dose-limiting toxicities or pharmacokinetic interactions in these patients, so the phase 2 dose of saracatinib was 175 mg daily.
In phase 2, patients were randomized to receive saracatinib plus docetaxel or placebo plus docetaxel.
Results: Safety and efficacy
“In terms of efficacy, the trial failed to meet its primary endpoint of demonstrating an improvement in progression-free survival. Indeed, there was a trend toward an improvement in progression-free survival for patients receiving placebo,” Dr. Jones said. “Similarly, in this key secondary endpoint of overall survival, there was no benefit from the addition of saracatinib. And again, there was a trend toward an improved survival in patients receiving placebo.”
The median progression-free survival was 19 weeks with saracatinib and 29 weeks with placebo (adjusted hazard ratio, 1.348).
The median overall survival was 62 weeks with saracatinib and 83 weeks with placebo (adjusted HR, 1.422).
Furthermore, there were no significant differences between the treatment arms for two other efficacy endpoints – maximum absolute change in prostate-specific antigen levels and absolute change in circulating tumor cell count from baseline to cycle three.
However, grade 3 or higher adverse events were more common in the saracatinib arm than in the placebo arm – 59% (41/69) and 41% (29/71), respectively.
The most common grade 3 or higher adverse events (in the saracatinib and placebo arms, respectively) were neutropenia (25% vs. 8%), diarrhea (12% vs. 4%), and fatigue (6% vs. 4%).

Burnout rates in ICU staff fueled by shortages, overtime
Health care professionals working in critical care settings have been overburdened because of the plethora of COVID-19 cases, which has led to symptoms of burnout in both physicians and nurses, findings from a new study show.
“Overburdening ICU professionals during an extended period of time leads to burnout,” said lead study author Niek Kok, MSc, of IQ healthcare, Radboud University Medical Center, Radboud Institute for Health Sciences, Nijmegen, the Netherlands. “All ICU professionals are at the risk of this, and in our study, the incidence of physicians experiencing burnout was significantly higher than that of nurses in June 2020.”
This burnout can be explained by conditions caused by the pandemic, he noted, such as the scarcity of staff and resources and having to work with colleagues who were not qualified to work in critical care but who were there out of necessity.
Mr. Kok presented the findings of the study at the Critical Care Congress sponsored by the Society of Critical Care Medicine.
Burnout highest among critical care physicians
The ICU can be a stressful environment for both patients and health care personnel, and burnout is not uncommon among ICU clinicians. However, COVID-19 has amplified the degree of burnout being experienced by clinicians working in this setting. Critical care physicians now top the list of physicians experiencing burnout, at 51%, up from 44% last year, according to the Medscape report ‘Death by 1000 Thousand Cuts’: Physician Burnout and Suicide Report 2021.
The Medscape Nurse Career Satisfaction Report 2020, while not restricted to those working in critical care, also reported higher rates of burnout, compared with the prepandemic period. The percentage of nurses reporting being “very burned out” prior to the pandemic was 4%. Six months into the pandemic, that percentage soared to 18%.
In this study, Mr. Kok and colleagues examined the prevalence and incidence of burnout symptoms and moral distress in health care professionals working in the ICU, both before and during the COVID-19 pandemic.
“When the COVID-19 pandemic surfaced in the Netherlands, the health care professionals in our hospitals were motivated to do everything they could to provide the best care possible,” said Mr. Kok. “Many of the ICU professionals immediately realized that they would have to work longer hours.”
However, the health care professionals that he spoke with did have mixed feelings. Some were afraid of being infected with the virus, while others said that “it was very interesting times for them and that gave them extra motivation to do the work.
“Some physicians [and] the WHO warned that COVID-19 is not going to weathered by a heroic sprint – it is an arduous marathon that is going to go hand in hand with burnout symptoms,” Mr. Kok added. “It will eat away at our qualified ICU staff.”
Before and after data on burnout
It was widely believed that the COVID-19 pandemic would increase burnout symptoms, as had been demonstrated in studies of previous pandemics. However, Mr. Kok emphasized that there are no before and after measurements that transcend cross-sectional designs.
“The claim [has been] that it increases burnout – but there are no assessments of how it progresses in ICU professionals through time,” he said. “So what we really need is a comparison [of] before and after the pandemic.”
It is quite difficult to obtain this type of information because disruptive events like the COVID-19 pandemic cannot be predicted, he said. Thus, it is challenging to get a baseline measurement. But Mr. Kok pointed out that the study has both “before and after” measurements.
“By coincidence really, we had baseline data to measure the impact of the COVID-19 pandemic and had information that was collected before the pandemic,” he said.
In January 2020, a study began looking at the effects of ethics meetings on moral distress in ICU professionals. Data had been collected on moral distress and burnout on ICU professionals in December 2019. The first COVID-19 cases appeared in the Netherlands in February 2020.
A follow-up study was then conducted in May and June 2020, several months into the pandemic.
The longitudinal open cohort study included all ICU personnel who were working in five units within a single university medical center, plus another adult ICU that was based in a separate teaching hospital.
A total of 352 health care professionals responded to a baseline survey in October through December 2019, and then 233 responded to a follow-up survey sent in May and June 2020. The authors measured burnout symptoms and moral distress with the Maslach Burnout Inventory and the Moral Distress Scale, respectively.
Findings
The overall prevalence of burnout symptoms was 23.0% prior to the pandemic, and that jumped to 36.1% at post-peak time. Higher rates of burnout were reported by nurses (38.0%) than physicians (28.6%).
However, the incidence rate of new burnout cases was higher among physicians, compared with nurses (26.7% vs 21.9%). Not surprisingly, a higher prevalence of burnout symptoms was observed in the post-peak period for all clinicians (odds ratio, 1.83; 95% confidence interval, 1.32-2.53), and was higher for nurses (odds ratio, 1.77; 95% confidence interval, 1.03-3.04), for those working overtime (OR, 2.11; 95% CI, 1.48-3.02), and for personnel who directly engaged in patient care (OR, 1.87; 95% CI, 1.35-2.60).
Physicians in general were much more likely to develop burnout symptoms related to the pandemic, compared with nurses (OR, 3.56; 95% CI, 1.06-12.21).
When looking at findings on moral distress, Kok pointed out that it often arises in situations when the health care professional knows the right thing to do but is prevented from doing so. “Morally distressful situations all rose from December to June,” said Mr. Kok. “Scarcity was the most distressing. The other was where colleagues were perceived to be less skilled, and this had to do with the recruitment of people from outside of the ICU to provide care.”
Moral distress from scarcity and unskilled colleagues were both significantly related to burnout, he noted.
In the final model, working in a COVID-19 unit, stress from scarcity of resources and people, stress from unskilled colleagues, and stress from unsafe conditions were all related to burnout. “The stress of physicians was significantly higher,” said Kok. “Even though nurses had higher baseline burnout, it became less pronounced in June 2020. This indicates that burnout was significantly higher in physicians.”
Thus, Mr. Kok and colleagues concluded that overburdening ICU professionals during an extended period of time leads to burnout, and all ICU workers are at risk.
Burnout rates higher in physicians
Weighing in on the study, Greg S. Martin, MD, FCCP, professor of medicine in the division of pulmonary, allergy, critical care and sleep medicine, Emory University, Atlanta, noted that the differences observed between physicians and nurses may have to do with the fact that “nurses have been smoldering all along and experiencing higher rates of burnout.
“They may have adapted better to the pandemic conditions, since they are more used to working overtime and short staffed, and spending far more time at the bedside,” he said. “Because of the volume of patients, physicians may be spending more hours doing patient care and are experiencing more burnout.”
For physicians, this may be a more significant change in the workload, as well as the complexity of the situation because of the pandemic. “Many things layer into it, such as [the fact] that there are no families present to give patients support, the complexity of care of these patients, and things like lack of PPE,” Dr. Martin said.
The study did not differentiate among physician groups, so it is unclear if the affected physicians were residents, fellows, or more senior staff. “Residents are often quite busy already, and don’t usually have the capacity to add more to their schedules, and maybe attendings were having to spend more time doing patient care,” Dr. Martin said. “In the United States, at least some personnel were restricted from working with COVID-19 patients. Medical students were removed in many places as well as nonessential staff, so that may have also added to their burnout.”
The study was conducted in the Netherlands, so there may be differences in the work environment, responsibilities of nurses vs. physicians, staffing, and so on. “But it still shows that burnout is very real among doctors and nurses working in the ICU in pandemic conditions,” he said.

Psychiatrist recounts haunting ordeal with an anonymous stalker
Looking back on his experience of being stalked by a former patient for nearly 1 year, William J. Newman, MD, regrets not reaching out to colleagues about the patient boundary violations earlier than he did.
“My mindset was: ‘Maybe I did something wrong that created this,’ ” Dr. Newman, professor and interim chair of psychiatry at Saint Louis University, said during an annual psychopharmacology update held by the Nevada Psychiatric Association. “That’s a common theme among victims of stalking, being kind of embarrassed and not wanting to share it with other people.”
Dr. Newman’s ordeal began in August 2014, when the first of several threatening emails messages were sent to his account at the University of California, Davis, where he held a faculty post and worked on the teaching service at the Sacramento Mental Health Treatment Center, a county hospital that serves mainly uninsured or underinsured populations. The messages always contained a nonspecific email recipient name and the first wasn’t terribly worrisome, Dr. Newman said. It basically read (profanities excluded): “What is wrong with you? Leave me alone. All I want is some privacy.”
About 3 months later, he received another message in a similar writing pattern, but the name of the sender was “god devil,” which raised a red flag to him. “Once you start to get religious concepts, people are compelled to commit acts when they believe they’re doing so beyond the laws of the land and are doing so for a religious purpose,” said Dr. Newman, who is immediate past president of the American Academy of Psychiatry and the Law.
The content of the message contained the first name of a coworker and phrasing inferring suicide, which gave Dr. Newman a hint that it was someone he had cared for at the mental health treatment center, “but as anybody who has worked on a busy inpatient service can tell you, you encounter several suicidal patients, and this didn’t really narrow it down,” he said. “This told me the person had presented after a suicide attempt. In some ways, that made me a little more concerned, because because they don’t really worry about the consequences of being shot by law enforcement or dying in an attack.”
Dr. Newman contacted the university’s information technology team, which was able to trace all messages to an IP address from a computer located at a downtown branch of the public library, which had surveillance video. Armed with this information, he contacted the Sacramento Police Department to see if they would help. He had “what I can only describe as an unsatisfying and somewhat condescending conversation with an officer, who said: ‘Sir, we can’t just go around asking people questions without knowing they did something wrong. There’s nothing we’re going to do.’ ”
Between November 2014 and May 2015, Dr. Newman continued to receive periodic messages from the individual of varied length and intensity.
“Some messages were more disorganized and difficult to follow, while others were very intense and pointed about my imminent death,” he recalled. “I started to ignore these messages as much as possible, tried to put my head in the sand and move forward.”
However, one phrase contained in a message read “you won’t even recognize me,” which gave Dr. Newman pause. “It highlighted the idea that because I don’t know who this is, they could walk up to me on the sidewalk, and I would have no idea, which in its own right is somewhat terrorizing.”
At this point, he contacted the police again, telling them he was fearful for his imminent safety. He also met with his department chair and administrators, who helped Dr. Newman develop a plan to enter and exit the hospital at different times. Then, in May 2015, the stalker sent Dr. Newman another email message threatening not only his life, but the lives of his colleagues at the hospital.
“This was viewed as a terroristic threat, because [it inferred that] other people were going to be shot other than just me,” he said.
After this, Dr. Newman’s administrators contacted the police about the threat, who identified the individual through video surveillance footage at the public library and began to search for him. It was a patient who had been on testosterone and previously had sent similar messages to another mental health provider in town and wound up showing up at that person’s office with a loaded firearm.
“At that point, the police were called to the scene, picked the individual up, and took him to a local emergency room where he was placed on an involuntary 5150 psychiatric hold,” he said. “It was frustrating to me that this was very much minimized and kind of put to the side.”
Once he learned the stalker’s name, Dr. Newman had no recollection of the individual. “The patient had presented after a carbon monoxide overdose, had been sent to a local emergency room and came to my service,” he said. “It was a very nonconfrontational hospitalization, nothing out of the ordinary.”
At this point, the stalker was still at large, so Dr. Newman wrote farewell notes to his wife, children, and loved ones, “just in case,” he said. “I had those tucked away. That wasn’t an overly pleasant experience.” He also lived away from his family outside of Sacramento while police searched for his stalker.
In late May 2015, police located and arrested the individual, and Dr. Newman began a series of conversations with the District Attorney’s office. “They told me there were seven terroristic threat charges that had been levied. They said they were taking this very seriously and [that the case] would be going to trial.” About 1 year later, after Dr. Newman’s move to Missouri, the District Attorney indicated that there would be a court trial and that Dr. Newman would be asked to serve as a fact witness. “I gave them all the information I had, talked to investigators, and the process was moving along for about a year to the point that they had an anticipated trial date,” he said. About 1 year later, he received an automated phone message which stated that the individual had been released from jail. He called the District Attorney to ask what happened.
“He said the judge didn’t really want to deal with this [case] anymore, and accepted a plea with time served and released him,” Dr. Newman said. “That was the outcome of the situation.”
According to a 1997 study of 100 stalking victims, 94% made major lifestyle changes after their ordeal, 82% modified usual activities, 73% increased security measures, 70% curtailed social outings, 53% decreased/stopped work or school, and 39% relocated. “You do change a lot of what you do and how you do it in your life when you’ve had this experience, especially when it’s been a chronic experience for months or years,” said Dr. Newman, who is also medical director of adult psychiatric inpatient services for Saint Louis University. “To this day I get antsy any time I think about the story or prepare to talk about it. It remains uncomfortable even 6 years later, even without an ongoing direct threat at this point.”
The physiological impact of chronic stalking also takes its toll. The body releases adrenaline and cortisol as part of the fight or flight response, while chronic stress “is when you feel an increased stress response and have adrenaline and cortisol elevated for an extended period of time,” he said. “There are negative impacts in terms of increased inflammation in the body and in the brain. I have spoken to several professionals who have been stalked by former patients. Commonly, they have been diagnosed in the period after that with an autoimmune illness or a cancer. Less than a year after my stalking situation ended, I was diagnosed with a metastatic cancer and had to start chemotherapy. I would not at all be surprised that those things are highly related to one another.”
When patient boundary violations start to become problematic or worrisome, Dr. Newman advised reaching out to colleagues and law enforcement for help. “Don’t let it go on insidiously for an extended period of time,” he said. “I think that was the biggest lesson I learned.”
He reported having no financial disclosures.

Expert calls for paradigm shift in lab monitoring of some dermatology drugs
From time to time, Joslyn Kirby, MD, asks other physicians about their experience with certain medications used in dermatology, especially when something new hits the market.
“Sometimes I get an answer like, ‘The last time I used that medicine, my patient needed a liver transplant,’ ” Dr. Kirby, associate professor of dermatology, Penn State University, Hershey, said during the Orlando Dermatology Aesthetic and Clinical Conference. “It’s typically a story of something rare, uncommon, and awful. The challenge with an anecdote is that for all its power, it has a lower level of evidence. But it sticks with us and influences us more than a better level of evidence because it’s a situation and a story that we might relate to.”
Dr. Kirby said that when she thinks about managing side effects from drugs used in dermatology, it usually relates to something common and low-risk such as sore, dry skin with isotretinoin use. In contrast, if there is an uncommon but serious side effect, then mitigation rather than management is key. “I want to mitigate the risk – meaning warn my patient about it or be careful about how I select my patients when it is a serious side effect that happens infrequently,” she said. “The worst combination is a frequent and severe side effect. That is something we should avoid, for sure.”
Isotretinoin
But another aspect of prescribing a new drug for patients can be less clear-cut, Dr. Kirby continued, such as the rationale for routine lab monitoring. She began by discussing one of her male patients with moderate to severe acne. After he failed oral antibiotics and topical retinoids, she recommended isotretinoin, which carries a risk of hypertriglyceridemia-associated pancreatitis. “Early in my career, I was getting a lot of monthly labs in patients on this drug that were totally normal and not influencing my practice,” Dr. Kirby recalled. “We’ve seen studies coming out on isotretinoin lab monitoring, showing us that we can keep our patients safe and that we really don’t need to be checking labs as often, because lab changes are infrequent.”
In one of those studies, researchers evaluated 1,863 patients treated with isotretinoin for acne between Jan. 1, 2008, and June 30, 2017 (J Am Acad Dermatol. 2020 Jan;82[1]:72-9).Over time, fewer than 1% of patients screened developed grade 3 or greater triglyceride testing abnormalities, while fewer than 0.5% developed liver function testing (LFT) abnormalities. Authors of a separate systematic review concluded that for patients on isotretinoin therapy without elevated baseline triglycerides, or risk thereof, monitoring triglycerides is of little value (Br J Dermatol. 2017 Oct;177[4]:960-6). Of the 25 patients in the analysis who developed pancreatitis on isotretinoin, only 3 had elevated triglycerides at baseline.
“I was taught that I need to check triglycerides frequently due to the risk of pancreatitis developing with isotretinoin use,” Dr. Kirby said. “Lipid changes on therapy are expected, but they tend to peak early, meaning the first 3 months of treatment when we’re ramping up from a starting dose to a maintenance dose. It’s rare for somebody to be a late bloomer, meaning that they have totally normal labs in the first 3 months and then suddenly develop an abnormality. People are either going to demonstrate an abnormality early or not have one at all.”
When Dr. Kirby starts patients on isotretinoin, she orders baseline LFTs and a lipid panel and repeats them 60 days later. “If everything is fine or only mildly high, we don’t do more testing, only a review of systems,” she said. “This is valuable to our patients because fear of needles and fainting peak during adolescence.”
Spironolactone
The clinical use of regularly monitoring potassium levels in young women taking spironolactone for acne has also been questioned. The drug has been linked to an increased risk for hyperkalemia, but the prevalence is unclear. “I got a lot of normal potassium levels in these patients [when] I was in training and I really questioned, ‘Why am I doing this? What is the rationale?’ ” Dr. Kirby said.
In a study that informed her own practice, researchers reviewed the rate of hyperkalemia in 974 healthy young women taking spironolactone for acne or for an endocrine disorder with associated acne between Dec. 1, 2000, and March 31, 2014 (JAMA Dermatol. 2015 Sep;151[9]:941-4). Of the total of 1,802 serum potassium measurements taken during treatment, 13 (0.72%) were mildly elevated levels and none of the patients had a potassium level above 5.5 mEq/L. Retesting within 1 to 3 weeks in 6 of 13 patients with elevated levels found that potassium levels were normal. “The recommendation for spironolactone in healthy women is not to check the potassium level,” Dr. Kirby said, adding that she does counsel patients about the risk of breast tenderness (which can occur 5% to 40% of the time) and spotting (which can occur in 10% to 20% of patients). Gynecomastia can occur in 10% to 30% of men, which is one of the reasons she does not use spironolactone in male patients.
TB testing and biologics
Whether or not to test for TB in patients with psoriasis taking biologic therapies represents another conundrum, she continued. Patients taking biologics are at risk of reactivation of latent TB infection, but in her experience, package inserts contain language like “perform TB testing at baseline, then periodically,” or “use at baseline, then with active TB symptoms,” and “after treatment is discontinued.”
“What the inserts didn’t recommend was to perform TB testing every year, which is what my routine had been,” Dr. Kirby said. “In the United States, thankfully we don’t have a lot of TB.” In a study that informed her own practice, researchers at a single academic medical center retrospectively reviewed the TB seroconversion rate among 316 patients treated with second-generation biologics (J Am Acad Dermatol. 2020 Oct 1;S0190-9622[20]32676-1. doi: 10.1016/j.jaad.2020.09.075). It found that only six patients (2%) converted and had a positive TB test later during treatment with the biologic. “Of these six people, all had grown up outside the U.S., had traveled outside of the U.S., or were in a group living situation,” said Dr. Kirby, who was not affiliated with the study.
“This informs our rationale for how we can do this testing. If insurance requires it every year, fine. But if they don’t, I ask patients about travel, about their living situation, and how they’re feeling. If everything’s going great, I don’t order TB testing. I do favor the interferon-gamma release assays because they’re a lot more effective than PPDs [purified protein derivative skin tests]. Also, PPDs are difficult for patients who have a low rate of returning to have that test read.”
Terbinafine for onychomycosis
Dr. Kirby also discussed the rationale for ordering regular LFTs in patients taking terbinafine for onychomycosis. “There is a risk of drug-induced liver injury from taking terbinafine, but it’s rare,” she said. “Can we be thoughtful about which patients we expose?”
Evidence suggests that patients with hyperkeratosis greater than 2 mm, with nail matrix involvement, with 50% or more of the nail involved, or having concomitant peripheral vascular disease and diabetes are recalcitrant to treatment with terbinafine
(J Am Acad Dermatol. 2019 Apr;80[4]:853-67). “If we can frame this risk, then we can frame it for our patients,” she said. “We’re more likely to cause liver injury with an antibiotic. When it comes to an oral antifungal, itraconazole is more likely than terbinafine to cause liver injury. The rate of liver injury with terbinafine is only about 2 out of 100,000. It’s five times more likely with itraconazole and 21 times more likely with Augmentin.”
She recommends obtaining a baseline LFT in patients starting terbinafine therapy “to make sure their liver is normal from the start.” In addition, she advised, “let them know that there is a TB seroconversion risk of about 1 in 50,000 people, and that if it happens there would be symptomatic changes. They would maybe notice pruritus and have a darkening in their urine, and they’d have some flu-like symptoms, which would mean stop the drug and get some care.”
Dr. Kirby emphasized that a patient’s propensity for developing drug-induced liver injury from terbinafine use is not predictable from LFT monitoring. “What you’re more likely to find is an asymptomatic LFT rise in about 1% of people,” she said.
She disclosed that she has received honoraria from AbbVie, ChemoCentryx, Incyte, Janssen, Novartis, and UCB Pharma.
From time to time, Joslyn Kirby, MD, asks other physicians about their experience with certain medications used in dermatology, especially when something new hits the market.
“Sometimes I get an answer like, ‘The last time I used that medicine, my patient needed a liver transplant,’ ” Dr. Kirby, associate professor of dermatology, Penn State University, Hershey, said during the Orlando Dermatology Aesthetic and Clinical Conference. “It’s typically a story of something rare, uncommon, and awful.

“I was taught that I need to check triglycerides frequently due to the risk of pancreatitis developing with isotretinoin use,” Dr. Kirby said. “Lipid changes on therapy are expected, but they tend to peak early, meaning the first 3 months of treatment when we’re ramping up from a starting dose to a maintenance dose. It’s rare for somebody to be a late bloomer, meaning that they have totally normal labs in the first 3 months and then suddenly develop an abnormality. People are either going to demonstrate an abnormality early or not have one at all.”
When Dr. Kirby starts patients on isotretinoin, she orders baseline LFTs and a lipid panel and repeats them 60 days later. “If everything is fine or only mildly high, we don’t do more testing, only a review of systems,” she said. “This is valuable to our patients because fear of needles and fainting peak during adolescence.”
Spironolactone
The clinical use of regularly monitoring potassium levels in young women taking spironolactone for acne has also been questioned. The drug has been linked to an increased risk for hyperkalemia, but the prevalence is unclear. “I got a lot of normal potassium levels in these patients [when] I was in training and I really questioned, ‘Why am I doing this? What is the rationale?’ ” Dr. Kirby said.
In a study that informed her own practice, researchers reviewed the rate of hyperkalemia in 974 healthy young women taking spironolactone for acne or for an endocrine disorder with associated acne between Dec. 1, 2000, and March 31, 2014 (JAMA Dermatol. 2015 Sep;151[9]:941-4). Of the total of 1,802 serum potassium measurements taken during treatment, 13 (0.72%) were mildly elevated levels and none of the patients had a potassium level above 5.5 mEq/L. Retesting within 1 to 3 weeks in 6 of 13 patients with elevated levels found that potassium levels were normal. “The recommendation for spironolactone in healthy women is not to check the potassium level,” Dr. Kirby said, adding that she does counsel patients about the risk of breast tenderness (which can occur 5% to 40% of the time) and spotting (which can occur in 10% to 20% of patients). Gynecomastia can occur in 10% to 30% of men, which is one of the reasons she does not use spironolactone in male patients.
TB testing and biologics
Whether or not to test for TB in patients with psoriasis taking biologic therapies represents another conundrum, she continued. Patients taking biologics are at risk of reactivation of latent TB infection, but in her experience, package inserts contain language like “perform TB testing at baseline, then periodically,” or “use at baseline, then with active TB symptoms,” and “after treatment is discontinued.”
“What the inserts didn’t recommend was to perform TB testing every year, which is what my routine had been,” Dr. Kirby said. “In the United States, thankfully we don’t have a lot of TB.” In a study that informed her own practice, researchers at a single academic medical center retrospectively reviewed the TB seroconversion rate among 316 patients treated with second-generation biologics (J Am Acad Dermatol. 2020 Oct 1;S0190-9622[20]32676-1. doi: 10.1016/j.jaad.2020.09.075). It found that only six patients (2%) converted and had a positive TB test later during treatment with the biologic. “Of these six people, all had grown up outside the U.S., had traveled outside of the U.S., or were in a group living situation,” said Dr. Kirby, who was not affiliated with the study.
“This informs our rationale for how we can do this testing. If insurance requires it every year, fine. But if they don’t, I ask patients about travel, about their living situation, and how they’re feeling. If everything’s going great, I don’t order TB testing. I do favor the interferon-gamma release assays because they’re a lot more effective than PPDs [purified protein derivative skin tests]. Also, PPDs are difficult for patients who have a low rate of returning to have that test read.”
Terbinafine for onychomycosis
Dr. Kirby also discussed the rationale for ordering regular LFTs in patients taking terbinafine for onychomycosis. “There is a risk of drug-induced liver injury from taking terbinafine, but it’s rare,” she said. “Can we be thoughtful about which patients we expose?”
Evidence suggests that patients with hyperkeratosis greater than 2 mm, with nail matrix involvement, with 50% or more of the nail involved, or having concomitant peripheral vascular disease and diabetes are recalcitrant to treatment with terbinafine
(J Am Acad Dermatol. 2019 Apr;80[4]:853-67). “If we can frame this risk, then we can frame it for our patients,” she said. “We’re more likely to cause liver injury with an antibiotic. When it comes to an oral antifungal, itraconazole is more likely than terbinafine to cause liver injury. The rate of liver injury with terbinafine is only about 2 out of 100,000. It’s five times more likely with itraconazole and 21 times more likely with Augmentin.”
She recommends obtaining a baseline LFT in patients starting terbinafine therapy “to make sure their liver is normal from the start.” In addition, she advised, “let them know that there is a TB seroconversion risk of about 1 in 50,000 people, and that if it happens there would be symptomatic changes. They would maybe notice pruritus and have a darkening in their urine, and they’d have some flu-like symptoms, which would mean stop the drug and get some care.”
Dr. Kirby emphasized that a patient’s propensity for developing drug-induced liver injury from terbinafine use is not predictable from LFT monitoring. “What you’re more likely to find is an asymptomatic LFT rise in about 1% of people,” she said.
She disclosed that she has received honoraria from AbbVie, ChemoCentryx, Incyte, Janssen, Novartis, and UCB Pharma.
From time to time, Joslyn Kirby, MD, asks other physicians about their experience with certain medications used in dermatology, especially when something new hits the market.
“Sometimes I get an answer like, ‘The last time I used that medicine, my patient needed a liver transplant,’ ” Dr. Kirby, associate professor of dermatology, Penn State University, Hershey, said during the Orlando Dermatology Aesthetic and Clinical Conference. “It’s typically a story of something rare, uncommon, and awful. The challenge with an anecdote is that for all its power, it has a lower level of evidence. But it sticks with us and influences us more than a better level of evidence because it’s a situation and a story that we might relate to.”
Dr. Kirby said that when she thinks about managing side effects from drugs used in dermatology, it usually relates to something common and low-risk such as sore, dry skin with isotretinoin use. In contrast, if there is an uncommon but serious side effect, then mitigation rather than management is key. “I want to mitigate the risk – meaning warn my patient about it or be careful about how I select my patients when it is a serious side effect that happens infrequently,” she said. “The worst combination is a frequent and severe side effect. That is something we should avoid, for sure.”
Isotretinoin
But another aspect of prescribing a new drug for patients can be less clear-cut, Dr. Kirby continued, such as the rationale for routine lab monitoring. She began by discussing one of her male patients with moderate to severe acne. After he failed oral antibiotics and topical retinoids, she recommended isotretinoin, which carries a risk of hypertriglyceridemia-associated pancreatitis. “Early in my career, I was getting a lot of monthly labs in patients on this drug that were totally normal and not influencing my practice,” Dr. Kirby recalled. “We’ve seen studies coming out on isotretinoin lab monitoring, showing us that we can keep our patients safe and that we really don’t need to be checking labs as often, because lab changes are infrequent.”
In one of those studies, researchers evaluated 1,863 patients treated with isotretinoin for acne between Jan. 1, 2008, and June 30, 2017 (J Am Acad Dermatol. 2020 Jan;82[1]:72-9).Over time, fewer than 1% of patients screened developed grade 3 or greater triglyceride testing abnormalities, while fewer than 0.5% developed liver function testing (LFT) abnormalities. Authors of a separate systematic review concluded that for patients on isotretinoin therapy without elevated baseline triglycerides, or risk thereof, monitoring triglycerides is of little value (Br J Dermatol. 2017 Oct;177[4]:960-6). Of the 25 patients in the analysis who developed pancreatitis on isotretinoin, only 3 had elevated triglycerides at baseline.
“I was taught that I need to check triglycerides frequently due to the risk of pancreatitis developing with isotretinoin use,” Dr. Kirby said. “Lipid changes on therapy are expected, but they tend to peak early, meaning the first 3 months of treatment when we’re ramping up from a starting dose to a maintenance dose. It’s rare for somebody to be a late bloomer, meaning that they have totally normal labs in the first 3 months and then suddenly develop an abnormality. People are either going to demonstrate an abnormality early or not have one at all.”
When Dr. Kirby starts patients on isotretinoin, she orders baseline LFTs and a lipid panel and repeats them 60 days later. “If everything is fine or only mildly high, we don’t do more testing, only a review of systems,” she said. “This is valuable to our patients because fear of needles and fainting peak during adolescence.”

Molecular insights suggest novel therapies for hidradenitis suppurativa
at the virtual annual congress of the European Academy of Dermatology and Venereology.
He presented highlights of a multicenter translational study, which utilized whole transcriptome analysis of lesional and nonlesional skin from patients with HS and normal controls along with quantitative real-time PCR and immunohistochemistry. The purpose was to further define the molecular taxonomy of this inflammatory disease. And while this objective was achieved, the results also underscored a truism regarding the painful and scarring disease: “HS is characterized by an ever-growing complexity, which translates into multiple potential mechanistic drivers,” observed Dr. da Costa, head of immunology precision medicine at AstraZeneca in Gothenburg, Sweden.
Indeed, the study identified a panel of immune-related drivers in HS that influence innate immunity and cell differentiation in follicular and epidermal keratinocytes. The research by Dr. da Costa and coinvestigators identified a broad array of promising novel therapeutic targets in HS.
“Our findings provide evidence of an inflammatory process coupled with impaired barrier function, altered epidermal cell differentiation, and possibly abnormal microbiome activity which can be seen at the follicular and epidermal keratinocytes and also to a minor degree at the level of the skin glands,” Dr. da Costa said.
There is a huge unmet need for new therapies for HS, since at present adalimumab (Humira) is the only approved medication for this debilitating inflammatory disease. Some good news that emerged from this translational study is that some of the novel molecular mediators implicated in HS are targeted by multiple Food and Drug Administration–approved therapies that have other indications. From a drug development standpoint, repurposing a commercially available drug for a novel indication is a much more efficient and less costly endeavor than is necessary to establish the safety and efficacy of an unproven new agent.
The translational work demonstrated that the proteins calgranulin-A and -B and serpin-B4 were strongly expressed in the hair root sheaths of patients with HS. Connexin-32 and koebnerisin were present in stratum granulosum, matrix metallopeptidase-9 was strongly expressed in resident monocytes, small prolin-rich protein 3 in apocrine sweat glands and ducts as well as in sebaceous glands and ducts, and transcobalamin-1 was prominent in stratum spinosum.
Of the 19 key molecular mediators of HS identified in the study, FDA-approved agents are already available that target 12 of them. For example, apremilast (Otezla) targets interferon-gamma and tumor necrosis factor–alpha. Gentamicin targets growth arrest-specific 6 (GAS6) and interleukin-17 (IL-17). Secukinumab (Cosentyx) and ixekizumab (Taltz) target IL-17A, and brodalumab (Siliq) more broadly targets IL-17A as well as all the other IL-17 receptors. Thalidomide targets hepatocyte growth factor (HGF) and TNF-alpha. Spironolactone targets androgen receptor (AR) and TNF-alpha. Colchicine targets tubulin. Anakinra (Kineret) homes in on the IL-1 receptor. And prednisone targets NFxB.
Other key molecular mediators of HS, which are targeted by commercially available drugs, include epidermal growth factor (EGF), macrophage colony-stimulating factor (MCSF), epiregulin (EREG), fibroblast growth factor 1 (FGF1), FGF2, insulin-like growth factor 2 (IGF2), and IL-6, according to Dr. da Costa.
In addition, clinical trials are underway in HS involving totally investigational agents, including several Janus kinase inhibitors and tyrosine kinase 2 inhibitors.
The work described by Dr. da Costa had multiple funding sources, including the European Hidradenitis Suppurativa Foundation, the University of Copenhagen, the Icahn School of Medicine at Mount Sinai, AstraZeneca, and the German Federal Ministry of Education and Research. Dr. da Costa is an employee of AstraZeneca, Gothenburg, Sweden.

FROM THE EADV CONGRESS
Anybody for a nanobody? Novel psoriasis therapy impresses in phase 2b
in a phase 2b randomized trial, Kim A. Papp, MD, PhD, reported at the annual congress of the European Academy of Dermatology and Venereology.
A nanobody is a tiny antibody fragment with a much smaller molecular weight than the monoclonal antibodies utilized today in treating psoriasis or atopic dermatitis. The sonelokinab nanobody, derived from animals in the camel family, is a recombinant sequence-optimized nanobody specific for human IL-17F, IL-17A, the heterodimer IL-17A/F, and serum albumin. The binding to serum albumin give sonelokinab a lengthy half-life of 10-12 hours, which may be therapeutically relevant, explained Dr. Papp, president and founder of Probity Medical Research in Waterloo, Ont.
He presented the 24-week results of a multicenter, double-blind, double-dummy randomized trial including 313 North American and European adults with an average 18-year history of psoriasis and a baseline Psoriasis Area and Severity Index (PASI) score of about 21. They were randomized to one of six treatment arms for the first 12 weeks: subcutaneous injection of sonelokinab at 30, 60, or 120 mg at weeks 0, 2, 4, and 8; enhanced–loading-dose sonelokinab at 120 mg every 2 weeks through week 10; the IL-17A inhibitor secukinumab (Cosentyx) at its standard dosing as an active comparator; or placebo. Data analysis was by rigorous nonresponder imputation, meaning anyone who didn’t complete the study was scored as a nonresponder.
“This yields a conservative data analysis somewhat biased against sonelokinab,” the dermatologist pointed out.
The primary outcome in the trial was the week-12 rate of an Investigator’s Global Assessment score of 0 or 1, indicative of clear or almost clear skin. This was achieved in 88.2% of patients in the highest-dose arm of sonelokinab. That group also had a week-12 PASI 90 response rate of 76.5% and a PASI 100 response rate of 33.3%. By comparison, patients on standard-dose secukinumab had a less robust week-12 IGA 0/1 rate of 77.4%, a PASI 90 of 64.2%, and a PASI 100 of 28.3%. Of note, however, this secukinumab performance was better than seen in the 30-mg sonelokinab group, and comparable to outcomes with 60 mg of sonelokinab.
Dose escalation was performed from weeks 12-24. Patients with a week-12 IGA score greater than 1 after being on sonelokinab at 30 or 60 mg were upgraded to 120 mg at week 12 and again every 4 weeks thereafter. Placebo-treated controls were switched to 120 mg at weeks 12, 14, 16, and every 4 weeks thereafter. The group on the enhanced–loading-dose sonelokinab moved to 120 mg every 4 weeks, while those who had gotten four doses of sonelokinab at 120 mg during the first 12 weeks were switched to 120 mg every 8 weeks. The secukinumab group remained on the approved dosing through week 24.
At week 24, superior outcomes were seen in the enhanced–loading-dose sonelokinab group, with an IGA 0/1 response rate of 94.2%, a PASI 90 of 90.4%, and a PASI 100 of 56.9%. The corresponding week-24 rates in patients on 120 mg of sonelokinab every 8 weeks from week 12 on were 80.4%, 79.2%, and 40.4%, outcomes similar to those seen with secukinumab.
The rapidity of response to sonelokinab at 120 mg was striking, with approximately one-third of treated patients achieving a PASI 90 response by week 4.
“This could reflect the smaller molecular profile. There is possibly rapid increased absorption or bioavailability, quicker time to achieving serum half-life, better penetration into target tissue, and perhaps more effective engagement at the target. All of those things are possibilities. These are things that are yet to be explored, but it’s very enticing to see that uncharacteristically rapid initial response. It’s all very gratifying – and tantalizing,” Dr. Papp said in response to an audience question.
The safety profile of sonelokinab was reassuring. The most common adverse events were nasopharyngitis in 13.5% of patients and pruritus in 6.7%, with most cases being mild or moderate. As with other IL-17 blockers, there was an increase in oral candidiasis. This side effect appeared to occur in dose-dependent fashion: The incidence was zero in the 30-mg group, 1.9% with 60 mg, 3.8% with sonelokinab at 120 mg without an enhanced loading dose, and 5.9% with the enhanced loading dose.
The study was conducted by Avillion in partnership with Merck. Dr. Papp reported receiving research funding from and serving as a consultant to those and numerous other pharmaceutical companies.

Dose escalation was performed from weeks 12-24. Patients with a week-12 IGA score greater than 1 after being on sonelokinab at 30 or 60 mg were upgraded to 120 mg at week 12 and again every 4 weeks thereafter. Placebo-treated controls were switched to 120 mg at weeks 12, 14, 16, and every 4 weeks thereafter. The group on the enhanced–loading-dose sonelokinab moved to 120 mg every 4 weeks, while those who had gotten four doses of sonelokinab at 120 mg during the first 12 weeks were switched to 120 mg every 8 weeks. The secukinumab group remained on the approved dosing through week 24.
At week 24, superior outcomes were seen in the enhanced–loading-dose sonelokinab group, with an IGA 0/1 response rate of 94.2%, a PASI 90 of 90.4%, and a PASI 100 of 56.9%. The corresponding week-24 rates in patients on 120 mg of sonelokinab every 8 weeks from week 12 on were 80.4%, 79.2%, and 40.4%, outcomes similar to those seen with secukinumab.
The rapidity of response to sonelokinab at 120 mg was striking, with approximately one-third of treated patients achieving a PASI 90 response by week 4.
“This could reflect the smaller molecular profile. There is possibly rapid increased absorption or bioavailability, quicker time to achieving serum half-life, better penetration into target tissue, and perhaps more effective engagement at the target. All of those things are possibilities. These are things that are yet to be explored, but it’s very enticing to see that uncharacteristically rapid initial response. It’s all very gratifying – and tantalizing,” Dr. Papp said in response to an audience question.
The safety profile of sonelokinab was reassuring. The most common adverse events were nasopharyngitis in 13.5% of patients and pruritus in 6.7%, with most cases being mild or moderate. As with other IL-17 blockers, there was an increase in oral candidiasis. This side effect appeared to occur in dose-dependent fashion: The incidence was zero in the 30-mg group, 1.9% with 60 mg, 3.8% with sonelokinab at 120 mg without an enhanced loading dose, and 5.9% with the enhanced loading dose.
The study was conducted by Avillion in partnership with Merck. Dr. Papp reported receiving research funding from and serving as a consultant to those and numerous other pharmaceutical companies.
in a phase 2b randomized trial, Kim A. Papp, MD, PhD, reported at the annual congress of the European Academy of Dermatology and Venereology.
A nanobody is a tiny antibody fragment with a much smaller molecular weight than the monoclonal antibodies utilized today in treating psoriasis or atopic dermatitis. The sonelokinab nanobody, derived from animals in the camel family, is a recombinant sequence-optimized nanobody specific for human IL-17F, IL-17A, the heterodimer IL-17A/F, and serum albumin. The binding to serum albumin give sonelokinab a lengthy half-life of 10-12 hours, which may be therapeutically relevant, explained Dr. Papp, president and founder of Probity Medical Research in Waterloo, Ont.
He presented the 24-week results of a multicenter, double-blind, double-dummy randomized trial including 313 North American and European adults with an average 18-year history of psoriasis and a baseline Psoriasis Area and Severity Index (PASI) score of about 21. They were randomized to one of six treatment arms for the first 12 weeks: subcutaneous injection of sonelokinab at 30, 60, or 120 mg at weeks 0, 2, 4, and 8; enhanced–loading-dose sonelokinab at 120 mg every 2 weeks through week 10; the IL-17A inhibitor secukinumab (Cosentyx) at its standard dosing as an active comparator; or placebo. Data analysis was by rigorous nonresponder imputation, meaning anyone who didn’t complete the study was scored as a nonresponder.
“This yields a conservative data analysis somewhat biased against sonelokinab,” the dermatologist pointed out.
The primary outcome in the trial was the week-12 rate of an Investigator’s Global Assessment score of 0 or 1, indicative of clear or almost clear skin. This was achieved in 88.2% of patients in the highest-dose arm of sonelokinab. That group also had a week-12 PASI 90 response rate of 76.5% and a PASI 100 response rate of 33.3%. By comparison, patients on standard-dose secukinumab had a less robust week-12 IGA 0/1 rate of 77.4%, a PASI 90 of 64.2%, and a PASI 100 of 28.3%. Of note, however, this secukinumab performance was better than seen in the 30-mg sonelokinab group, and comparable to outcomes with 60 mg of sonelokinab.

Neoadjuvant immunotherapy shows promise in stage III melanoma
The next dramatic , John M. Kirkwood, MD, predicted at a virtual forum on cutaneous malignancies jointly presented by the Postgraduate Institute for Medicine and Global Academy for Medical Education.
These agents have already demonstrated profound efficacy, first in stage IV metastatic disease and more recently as adjuvant therapy for resected stage III melanoma. Now, there is a great interest in learning whether by prescribing them preoperatively, patients might reduce their risk of advancing to metastatic disease. And neoadjuvant therapy offers an extremely attractive feature: It yields results in an accelerated fashion.
“The major problem with postoperative adjuvant trials in melanoma since 1984 is the long time to maturity. Many of us don’t want to wait the full 9 or 10 years for a full-bore, phase 3 adjuvant trial in stage III melanoma to mature,” explained Dr. Kirkwood, professor of medicine, dermatology, and translational science and coleader of the melanoma and skin cancer program at the University of Pittsburgh. “The opportunity to treat a patient who presents with a bulky lymph node, has a biopsy, and then can be treated for 3 or 6 weeks or sometimes even longer periods with a therapy that’s promising allows us to ask what’s going on in the tumor tissue, what’s going on in the clinical response at 3 or 6 weeks, and if there’s pathological complete or near-complete response under the microscope.”
Because pathological complete response is a strong predictor of relapse-free survival, this neoadjuvant-forward therapeutic strategy has the potential to provide patients and their physicians with an early forecast of likely clinical outcome only 4-6 weeks into treatment. Also, there is both preclinical and clinical evidence that neoadjuvant therapy may offer a survival advantage over adjuvant therapy, perhaps as a result of early treatment of micrometastatic disease. Another benefit of neoadjuvant therapy for melanoma is the resultant tumor shrinkage, which can permit less extensive surgery.
Dr. Kirkwood highlighted a phase 2 clinical trial conducted at the University of Pittsburgh to illustrate the potential of neoadjuvant therapy in melanoma. The ongoing single-arm study includes 32 patients with stage IIIB or IIIC resectable melanoma along with accessible tumor for biopsy and intratumoral injections of CMP-001, a toll-like receptor 9 agonist. According to the Eighth Edition of the American Joint Committee on Cancer staging manual, stage IIIB melanoma has a 10-year mortality of 23%, and stage IIIC disease has 40%.
CMP-001 triggers type 1 interferon production through activation of plasmacytoid dendritic cells. The resultant inflammatory response draws T cells into the tumor to enhance the response to immunotherapy, which in this study was nivolumab (Opdivo), a human programmed death ligand 1 (PD-L1)–blocking antibody. The neoadjuvant regimen consisted of seven once-weekly intratumoral injections of CMP-001, plus three 240-mg doses of nivolumab given at 2-week intervals. This was followed by resection, then 1 year of adjuvant therapy with nivolumab at 480 mg every 4 weeks and intratumoral CMP-001 every 4 weeks.
In an interim analysis, a major pathologic response occurred in an impressive 15 of 21 patients (71%) after 6 weeks of neoadjuvant therapy. Thirteen of the 15 had a pathologic complete response. Encouragingly, no one with a pathologic complete or near-complete response has relapsed to date.
“A pathologic complete response or near-complete response with neoadjuvant therapy appears to be a biomarker of durable disease control and is associated with excellent outcomes,” Dr. Kirkwood observed, adding that the Pittsburgh experience has been mirrored in reports from the Netherlands, Australia, and University of Texas M.D. Anderson Cancer Center, Houston, involving other neoadjuvant agents.
Other potential early biomarkers of favorable outcome with neoadjuvant therapy include CD8+ T cells in the tumor at baseline, tumor mutational burden, T-cell clonality, and a T-cell–inflamed gene-expression profile.
There were no dose-limiting toxicities or delays in surgery related to the neoadjuvant treatment.
Of note, imaging often inaccurately showed only a partial response in patients who actually had a pathologic complete response, meaning totally devoid of tumor, Dr. Kirkwood said.
Corroboration of these findings is planned in the national multicenter ECOG-ACRIN neoadjuvant trial EA6194.
“Consider referring to this trial any patients who present with bulky nodal disease for whom a treatment assessment at 4-6 weeks is desired in order to predict what the outcome may be,” he suggested.
Dr. Kirkwood reported receiving research grants from Amgen, BMS, Castle Biosciences, Checkmate, Immunocore, Iovance, and Novartis and serving as a consultant to a handful of companies.

COVID-19: Peginterferon lambda may prevent clinical deterioration, shorten viral shedding
and shorten the duration of viral shedding, according to results of a double-blind, placebo-controlled trial (NCT04354259).
Reductions in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA were greater with peginterferon lambda than with placebo from day 3 onward in the phase 2 study led by Jordan J. Feld, MD, of the Toronto Centre for Liver Disease. The findings were reported in The Lancet Respiratory Medicine.
Fewer side effects
To date in randomized clinical trials, efficacy in treatment of COVID-19 has been shown only for remdesivir and dexamethasone in hospitalized patients, and in an interim analysis of accelerated viral clearance for a monoclonal antibody infusion in outpatients.
Activity against respiratory pathogens has been demonstrated for interferon lambda-1, a type III interferon shown to be involved in innate antiviral responses. Interferons, Dr. Feld and coauthors stated, drive induction of genes with antiviral, antiproliferative and immunoregulatory properties, and early treatment with interferons might halt clinical progression and shorten the duration of viral shedding with reduced onward transmission. In addition, interferon lambdas (type III) use a distinct receptor complex with high expression levels limited to epithelial cells in the lung, liver, and intestine, leading to fewer side effects than other interferons, including avoiding risk of promoting cytokine storm syndrome.
The researchers investigated peginterferon lambda safety and efficacy in treatment of patients with laboratory-confirmed, mild to moderate COVID-19. Sixty patients (median age 46 years, about 60% female, about 50% White) were recruited from outpatient testing centers at six institutions in Toronto, and referred to a single ambulatory site. Patients were randomly assigned 1:1 to a single subcutaneous injection of peginterferon lambda 180 mcg or placebo within 7 days of symptom onset or, if asymptomatic, of their first positive swab. Mean time from symptom onset to injection was about 4.5 days, and about 18.5% were asymptomatic. The primary outcome was the proportion of patients negative for SARS-CoV-2 RNA on day 7 after the injection.
Greater benefit with higher baseline load
A higher baseline SARS-CoV-2 RNA concentration found in the peginterferon lambda group was found to be significantly associated with day 7 clearance (odds ratio [OR] 0.69 [95% confidence interval 0.51-0.87]; P = ·001). In the peginterferon lambda group, also, the mean decline in SARS-CoV-2 RNA was significantly larger than in the placebo group across all time points (days 3, 5, 7, and14). While viral load decline was 0.81 log greater in the treatment group (P = .14) by day 3, viral load decline increased to 1.67 log copies per mL by day 5 (P = .013) and 2.42 log copies per mL by day 7 (P = .0041). At day 14, the viral decline was 1.77 log copies per mL larger in the peginterferon lambda group (P = .048). The investigators pointed out that the difference in viral load decline between groups was greater in patients with high baseline viral load (at or above 106 copies per mL). In the peginterferon lambda high baseline viral load group, the reduction was 7.17 log copies per mL, versus 4.92 log copies per mL in the placebo group (P = .004).
More patients SARS-CoV-2 RNA negative
By day 7, 80% of patients in the peginterferon lambda group were negative for SARS-CoV-2 RNA, compared with 63% in the placebo group (P = .15). After baseline load adjustment, however, the peginterferon lambda treatment was significantly associated with day 7 clearance (OR 4·12 [95% CI 1·15-16·73]; P = .029).
Respiratory symptoms improved faster
Most symptoms in both groups were mild to moderate, without difference in frequency or severity. While symptom improvement was generally similar over time for both groups, respiratory symptoms improved faster with peginterferon lambda, with the effect more pronounced in the high baseline viral load group (OR 5·88 (0·81-42·46; P =. 079).
Laboratory adverse events, similar for both groups, were mild.
“Peginterferon lambda has potential to prevent clinical deterioration and shorten duration of viral shedding,” the investigators concluded.
“This clinical trial is important” because it suggests that a single intravenous dose of peginterferon lambda administered to outpatients with a positive SARS-CoV-2 nasopharyngeal swab speeds reduction of SARS-CoV-2 viral load, David L. Bowton, MD, FCCP, professor emeritus, Wake Forest Baptist Health, Winston-Salem, N.C., said in an interview. He observed that the smaller viral load difference observed at day 14 likely reflects host immune responses.
Dr. Bowton also noted that two placebo group baseline characteristics (five placebo group patients with anti-SARS-CoV-2 S protein IgG antibodies; two times more undetectable SARS-CoV-2 RNA at baseline assessment) would tend to reduce differences between the peginterferon lambda and placebo groups. He added that the study findings were concordant with another phase 2 trial of hospitalized COVID-19 patients receiving inhaled interferon beta-1a.
“Thus, interferons may find a place in the treatment of COVID-19 and perhaps other severe viral illnesses,” Dr. Bowton said.
The study was funded by the Toronto COVID-19 Action Initiative, University of Toronto, and the Ontario First COVID-19 Rapid Research Fund, Toronto General & Western Hospital Foundation.

Activity against respiratory pathogens has been demonstrated for interferon lambda-1, a type III interferon shown to be involved in innate antiviral responses. Interferons, Dr. Feld and coauthors stated, drive induction of genes with antiviral, antiproliferative and immunoregulatory properties, and early treatment with interferons might halt clinical progression and shorten the duration of viral shedding with reduced onward transmission. In addition, interferon lambdas (type III) use a distinct receptor complex with high expression levels limited to epithelial cells in the lung, liver, and intestine, leading to fewer side effects than other interferons, including avoiding risk of promoting cytokine storm syndrome.
The researchers investigated peginterferon lambda safety and efficacy in treatment of patients with laboratory-confirmed, mild to moderate COVID-19. Sixty patients (median age 46 years, about 60% female, about 50% White) were recruited from outpatient testing centers at six institutions in Toronto, and referred to a single ambulatory site. Patients were randomly assigned 1:1 to a single subcutaneous injection of peginterferon lambda 180 mcg or placebo within 7 days of symptom onset or, if asymptomatic, of their first positive swab. Mean time from symptom onset to injection was about 4.5 days, and about 18.5% were asymptomatic. The primary outcome was the proportion of patients negative for SARS-CoV-2 RNA on day 7 after the injection.
Greater benefit with higher baseline load
A higher baseline SARS-CoV-2 RNA concentration found in the peginterferon lambda group was found to be significantly associated with day 7 clearance (odds ratio [OR] 0.69 [95% confidence interval 0.51-0.87]; P = ·001). In the peginterferon lambda group, also, the mean decline in SARS-CoV-2 RNA was significantly larger than in the placebo group across all time points (days 3, 5, 7, and14). While viral load decline was 0.81 log greater in the treatment group (P = .14) by day 3, viral load decline increased to 1.67 log copies per mL by day 5 (P = .013) and 2.42 log copies per mL by day 7 (P = .0041). At day 14, the viral decline was 1.77 log copies per mL larger in the peginterferon lambda group (P = .048). The investigators pointed out that the difference in viral load decline between groups was greater in patients with high baseline viral load (at or above 106 copies per mL). In the peginterferon lambda high baseline viral load group, the reduction was 7.17 log copies per mL, versus 4.92 log copies per mL in the placebo group (P = .004).
More patients SARS-CoV-2 RNA negative
By day 7, 80% of patients in the peginterferon lambda group were negative for SARS-CoV-2 RNA, compared with 63% in the placebo group (P = .15). After baseline load adjustment, however, the peginterferon lambda treatment was significantly associated with day 7 clearance (OR 4·12 [95% CI 1·15-16·73]; P = .029).
Respiratory symptoms improved faster
Most symptoms in both groups were mild to moderate, without difference in frequency or severity. While symptom improvement was generally similar over time for both groups, respiratory symptoms improved faster with peginterferon lambda, with the effect more pronounced in the high baseline viral load group (OR 5·88 (0·81-42·46; P =. 079).
Laboratory adverse events, similar for both groups, were mild.
“Peginterferon lambda has potential to prevent clinical deterioration and shorten duration of viral shedding,” the investigators concluded.
“This clinical trial is important” because it suggests that a single intravenous dose of peginterferon lambda administered to outpatients with a positive SARS-CoV-2 nasopharyngeal swab speeds reduction of SARS-CoV-2 viral load, David L. Bowton, MD, FCCP, professor emeritus, Wake Forest Baptist Health, Winston-Salem, N.C., said in an interview. He observed that the smaller viral load difference observed at day 14 likely reflects host immune responses.
Dr. Bowton also noted that two placebo group baseline characteristics (five placebo group patients with anti-SARS-CoV-2 S protein IgG antibodies; two times more undetectable SARS-CoV-2 RNA at baseline assessment) would tend to reduce differences between the peginterferon lambda and placebo groups. He added that the study findings were concordant with another phase 2 trial of hospitalized COVID-19 patients receiving inhaled interferon beta-1a.
“Thus, interferons may find a place in the treatment of COVID-19 and perhaps other severe viral illnesses,” Dr. Bowton said.
The study was funded by the Toronto COVID-19 Action Initiative, University of Toronto, and the Ontario First COVID-19 Rapid Research Fund, Toronto General & Western Hospital Foundation.

Neighborhood police complaints tied to Black preterm birth rates
The more complaints of excessive force by police reported by neighborhood residents, the more likely it is that Black pregnant people living in that neighborhood will deliver preterm, according to findings from a new study presented Jan. 28 at the virtual Society for Maternal-Fetal Medicine 2021 Annual Pregnancy Meeting.
“We know there are significant racial disparities in preterm birth which aren’t fully explained by traditional risk factors, like being older, having health problems like high blood pressure, or limited income,” Alexa Freedman, PhD, a postdoctoral fellow at NorthShore University HealthSystem and Northwestern University Institute for Policy Research, Evanston, Ill., told this news organization. “This has left many wondering if there are stressors unique to Black individuals that may be involved,” which has led to past research on the association of preterm birth with neighborhood segregation and historical “redlining” practices.
Black individuals have a substantially higher rate of preterm birth, compared with all other racial and ethnic groups in the US: 13.8% of Black infants born between 2016 and 2018 were preterm, compared with 11.6% among Native Americans – the next highest group – and 9.1% among White women.
“Studies have shown that psychosocial stress contributes to preterm birth disparities, potentially through several physiologic pathways that impact pregnancy outcomes,” Dr. Freedman told attendees. “Pregnant Black individuals have been reported to experience greater psychosocial stress regardless of socioeconomic status, possibly secondary to experiences of racism and discrimination.”
Though past research has examined neighborhood disadvantage and violence as stressors potentially contributing to preterm birth, little data exist on police–community relationships or police violence and pregnancy outcomes, despite being a “particularly salient stressor for Black individuals,” Dr. Freedman said. “Among pregnant Black individuals, prenatal depression has been correlated with concern about negative interactions between youth in their community and police.” To cite one example of the prevalence of racial bias in policing, she noted that “Chicago police are almost 10 times more likely to use force when interacting with a Black individual as compared [with] a White individual.”
The researchers therefore sought to determine whether a relationship existed between preterm birth rates and complaints regarding use of excessive force by police in the same neighborhood. They compiled records on all singleton live births from one Chicago hospital between March 2008 and March 2018, excluding those who lived outside Chicago, had a missing address, listed their race as “other,” or lacked data for specific other confounders.
Assessing police complaints within census blocks
The researchers obtained data on police complaints in Chicago from the Invisible Institute’s Citizen Police Data Project. They focused only on complaints of excessive use of force, “such as unnecessary physical contact and unnecessary display of a weapon,” Dr. Freedman said. They considered a person exposed in the neighborhood if a complaint was reported in her census block in the year leading up to birth. During their study period, more than 6,000 complaints of excessive force were reported across an estimated 70% of the blocks.
The study population had an average age of 31 and included 59.5% White, 12% Black, 20% Hispanic, and 8.5% Asian people. Just over half the pregnancies (55%) were first-time pregnancies, and 3.3% of the population had a history of preterm birth (before 37 weeks). The researchers also gathered data to adjust for the study population’s:
- Age
- Parity (number of times the woman has given birth).
- Population size of census block.
- Exposure to a homicide on the block in the year leading up to birth.
- Socioeconomic status by block (based on a composite of median home value, median income, percentage of a high school diploma, and percentage employed).
“Those who lived in a block with an excessive force complaint were more likely to be Black, more likely to deliver preterm, and more likely to be exposed to homicide,” Dr. Freedman told attendees.
The proportion of pregnant women exposed to police complaints was 15.8%, and 10.2% lived in neighborhoods where a homicide occurred in the year leading up to birth. Within the group exposed to a homicide, 16.5% lived in a neighborhood with an excessive force complaint and 9.1% did not.
Overall, 8.1% of the population gave birth preterm. When stratified by whether or not they lived in a block with an excessive force complaint, the researchers found the proportion of preterm births was higher among those who did than those who did not (9.3% vs. 7.8%).
Both before and after adjusting for confounders, Black people were the only racial/ethnic group who had a significantly increased risk of preterm birth if they lived on a block with a complaint. They were nearly 30% more likely to deliver preterm if an excessive force complaint had been reported nearby (odds ratio, 1.29). The odds of preterm birth were slightly elevated for White people and slightly reduced for Hispanic and Asian people, but none of those associations reached significance.
In a sensitivity analysis comparing 189 Black individuals to themselves, the researchers compared those who had one preterm birth and one term birth. They found that the preterm birth was 32% more likely to occur in a year when an excessive force complaint was filed after adjusting for age and birth order (OR, 1.32; 95% confidence interval, 0.82-2.13).
“Police violence reflects just one component of structural racism,” Dr. Freedman said in an interview. “Our findings highlight the need to more thoroughly consider how these systemic and structural factors contribute to disparities in maternal and fetal health.”
Clinical and policy implications
The clinical implications of these findings focus on the need for obstetric clinical teams to understand patients’ stressors and to provide support and resources, according to Dr. Freedman’s mentor, Ann Borders, MD, MSc, MPH, a maternal-fetal medicine physician at NorthShore and Evanston Hospital and a clinical associate professor at the University of Chicago Pritzker School of Medicine.
“Potential strategies include training on improved listening and respectful patient-centered care, such as provided by the CDC Hear Her campaign, and consideration of universal social determinants of health screening during obstetric care,” Dr. Borders told this news organization..
Though the study included a large sample size and allowed the researchers to control for individual and neighborhood characteristics, Dr. Freedman acknowledged that census blocks may or may not correlate with the way individuals define their own neighborhoods. They also didn’t have the data to assess the quality of prenatal care or the type of preterm birth, but they are developing a qualitative study to determine the best ways of measuring exposure to police violence.
In addition, the researchers’ reliance only on formal police complaints could have underestimated prevalence of excessive force, and the study did not take into account people’s direct experience with police violence; police violence that occurs within a person’s social network; or police violence widely covered in the news.
It wasn’t possible for the researchers to verify whether excessive force actually occurred or whether the force might have been justified, and it instead relied on the fact that someone lodged a complaint because he or she perceived the action as excessive.
Allison Bryant Mantha, MD, MPH, vice chair for Quality, Equity, and Safety at Massachusetts General Hospital in Boston and a board member of SMFM, said she was impressed with the adjustment of homicide exposure as a proxy for neighborhood crime.
“Many might assume that reports of police misconduct might be a marker for a ‘dangerous neighborhood,’ and it was thoughtful of the authors to adjust their analyses for exposure to crime to demonstrate that, even above and beyond crime, reports of police misconduct seem to be associated with adverse outcomes,” Dr. Bryant Mantha, who moderated the session, said in an interview.
Confronting this issue goes beyond what clinicians can do on their own, Dr. Bryant Mantha suggested.
“The greatest change will come with addressing the structural racism that underlies differential exposure to police misconduct in communities in the first place,” she said. “Concurrent with this, however, clinicians may consider adding in an assessment of neighborhood characteristics to include reports of police misconduct as they screen for other social determinants of health. While we do not have intervention studies to demonstrate efficacy, it is not a huge leap to imagine that recognition of this burden in individuals’ lives, plus offering ways to manage stress or seek redress, could be of benefit.”
The research was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute on Minority Health and Health Disparities, and the Northwestern Medicine Enterprise Data Warehouse Pilot Data Program. Dr. Freedman, Dr. Borders, and Dr. Bryant Mantha have disclosed no relevant financial relationships.

Racial disparities in maternal morbidity persist even with equal access to care
An analysis of data from the U.S. military suggests that the maternal morbidity disparities between Black and White women cannot be attributed solely to differences in access to care and socioeconomics.
Even in the U.S. military health care system, where all service members have universal access to the same facilities and providers, researchers found substantial racial disparities in cesarean deliveries, maternal ICU admission, and overall severe maternal morbidity and mortality between Black patients and White patients, according to findings from a new study presented Jan. 28, 2021, at a meeting sponsored by the Society for Maternal-Fetal Medicine.
“This was surprising given some of the driving theories behind maternal race disparities encountered in this country, such as access to care and socioeconomic status, are controlled for in this health care system,” Capt. Jameaka Hamilton, MD, who presented the research, said in an interview. “Our findings indicate that there are likely additional factors at play which impact the obstetrical outcomes of women based upon their race, including systems-based barriers to accessing the military health care system which contribute to health care disparities, or in systemic or implicit biases which occur within our health care delivery.”
Plenty of recent research has documented the rise in maternal morbidity and mortality in the United States and the considerable racial disparities within those statistics. Black women are twice as likely to suffer morbidity and three to four times more likely to die in childbirth, compared with White women, Dr. Hamilton, an ob.gyn. from the San Antonio Uniformed Services Health Education Consortium at Ft. Sam Houston in San Antonio, Texas, reminded attendees. So far, much of this disparity has been attributed to social determinants of health.
Military retirees, active-duty personnel, and dependents, however, have equal access to federal health insurance and care at military health care facilities, or at covered civilian facilities where needed. Hence the researchers’ hypothesis that the military medical system would not show the same disparities by race that are seen in civilian populations.
The researchers analyzed maternal morbidity data from the Neonatal Perinatal Information Center from April 2018 to March 2019. The retrospective study included data from 13 military treatment facilities that had more than 1,000 deliveries per year. In addition to statistics on cesarean delivery and adult ICU admission, the researchers compared numbers on overall severe maternal morbidity based on the indicators defined by the Centers for Disease Control and Prevention.
The 15,305 deliveries included 23% Black patients and 77% White patients from the Air Force, Army, and Navy branches.
The cesarean delivery rate ranged from 19.4% to 35.5%. ICU admissions totaled 38 women, 190 women had postpartum hemorrhage, and 282 women experienced severe maternal morbidity. All three measures revealed racial disparities:
- Overall severe maternal morbidity occurred in 2.66% of Black women and 1.66% of White women (P =.0001).
- ICU admission occurred in 0.49% of Black women and 0.18% of White women (P =.0026).
- 31.68% of Black women had a cesarean delivery, compared with 23.58% of White women (P <.0001).
After excluding cases with blood transfusions, Black women were twice as likely to have severe maternal morbidity (0.64% vs. 0.32%). There were no significant differences in postpartum hemorrhage rates between Black and White women, but this analysis was limited by the small overall numbers of postpartum hemorrhage.
Among the study’s limitations were the inability to stratify patients by retiree, active duty, or dependent status, and the lack of data on preeclampsia rates, maternal age, obesity, or other preexisting conditions. In addition, the initial dataset included 61% of patients who reported their race as “other” than Black or White, limiting the number of patients whose data could be analyzed. Since low-volume hospitals were excluded, the outcomes could be skewed if lower-volume facilities are more likely to care for more complex cases, Dr. Hamilton added.
Allison Bryant Mantha, MD, MPH, vice chair for quality, equity, and safety in the ob.gyn. department at Massachusetts General Hospital, Boston, praised Dr. Hamilton’s work for revealing that differential access – though still problematic – cannot fully explain inequities between Black women and other women.
“The findings are not shocking given that what underlies some of these inequities – namely structural and institutional racism, and differential treatment within the system – are not exclusive to civilian health care settings,” Dr. Bryant Mantha, who moderated the session, said in an interview. “That said, doing the work to demonstrate this is extremely valuable.”
Although the causes of these disparities are systemic, Dr. Hamilton said individual providers can play a role in addressing them.
“There can certainly be more done to address this dangerous trend at the provider, hospital/institution, and national level,” she said. I think we as providers should continue to self-reflect and address our own biases. Hospitals and institutions should continue to develop policies that draw attention health care disparities.”
Completely removing these inequalities, however, will require confronting the racism embedded in U.S. health care at all levels, Dr. Bryant Mantha suggested.
“Ultimately, moving to an antiracist health care system – and criminal justice system, educational system, political system, etc. – and dismantling the existing structural racism in policies and practices will be needed to drive this change,” Dr. Bryant Mantha said. “Individual clinicians can use their voices to advocate for these changes in their health systems, communities, and states. Awareness of these inequities is critical, as is a sense of collective efficacy that we can, indeed, change the status quo.”

An analysis of data from the U.S. military suggests that the maternal morbidity disparities between Black and White women cannot be attributed solely to differences in access to care and socioeconomics.
Even in the U.S. military health care system, where all service members have universal access to the same facilities and providers, researchers found substantial racial disparities in cesarean deliveries, maternal ICU admission, and overall severe maternal morbidity and mortality between Black patients and White patients, according to findings from a new study presented Jan. 28, 2021, at a meeting sponsored by the Society for Maternal-Fetal Medicine.
“This was surprising given some of the driving theories behind maternal race disparities encountered in this country, such as access to care and socioeconomic status, are controlled for in this health care system,” Capt. Jameaka Hamilton, MD, who presented the research, said in an interview. “Our findings indicate that there are likely additional factors at play which impact the obstetrical outcomes of women based upon their race, including systems-based barriers to accessing the military health care system which contribute to health care disparities, or in systemic or implicit biases which occur within our health care delivery.”
Plenty of recent research has documented the rise in maternal morbidity and mortality in the United States and the considerable racial disparities within those statistics. Black women are twice as likely to suffer morbidity and three to four times more likely to die in childbirth, compared with White women, Dr. Hamilton, an ob.gyn. from the San Antonio Uniformed Services Health Education Consortium at Ft. Sam Houston in San Antonio, Texas, reminded attendees. So far, much of this disparity has been attributed to social determinants of health.
Military retirees, active-duty personnel, and dependents, however, have equal access to federal health insurance and care at military health care facilities, or at covered civilian facilities where needed. Hence the researchers’ hypothesis that the military medical system would not show the same disparities by race that are seen in civilian populations.
The researchers analyzed maternal morbidity data from the Neonatal Perinatal Information Center from April 2018 to March 2019. The retrospective study included data from 13 military treatment facilities that had more than 1,000 deliveries per year. In addition to statistics on cesarean delivery and adult ICU admission, the researchers compared numbers on overall severe maternal morbidity based on the indicators defined by the Centers for Disease Control and Prevention.
The 15,305 deliveries included 23% Black patients and 77% White patients from the Air Force, Army, and Navy branches.
The cesarean delivery rate ranged from 19.4% to 35.5%. ICU admissions totaled 38 women, 190 women had postpartum hemorrhage, and 282 women experienced severe maternal morbidity. All three measures revealed racial disparities:
- Overall severe maternal morbidity occurred in 2.66% of Black women and 1.66% of White women (P =.0001).
- ICU admission occurred in 0.49% of Black women and 0.18% of White women (P =.0026).
- 31.68% of Black women had a cesarean delivery, compared with 23.58% of White women (P <.0001).
After excluding cases with blood transfusions, Black women were twice as likely to have severe maternal morbidity (0.64% vs. 0.32%). There were no significant differences in postpartum hemorrhage rates between Black and White women, but this analysis was limited by the small overall numbers of postpartum hemorrhage.
Among the study’s limitations were the inability to stratify patients by retiree, active duty, or dependent status, and the lack of data on preeclampsia rates, maternal age, obesity, or other preexisting conditions. In addition, the initial dataset included 61% of patients who reported their race as “other” than Black or White, limiting the number of patients whose data could be analyzed. Since low-volume hospitals were excluded, the outcomes could be skewed if lower-volume facilities are more likely to care for more complex cases, Dr. Hamilton added.
Allison Bryant Mantha, MD, MPH, vice chair for quality, equity, and safety in the ob.gyn. department at Massachusetts General Hospital, Boston, praised Dr. Hamilton’s work for revealing that differential access – though still problematic – cannot fully explain inequities between Black women and other women.
“The findings are not shocking given that what underlies some of these inequities – namely structural and institutional racism, and differential treatment within the system – are not exclusive to civilian health care settings,” Dr. Bryant Mantha, who moderated the session, said in an interview. “That said, doing the work to demonstrate this is extremely valuable.”
Although the causes of these disparities are systemic, Dr. Hamilton said individual providers can play a role in addressing them.
“There can certainly be more done to address this dangerous trend at the provider, hospital/institution, and national level,” she said. I think we as providers should continue to self-reflect and address our own biases. Hospitals and institutions should continue to develop policies that draw attention health care disparities.”
