Will my child outgrow the eczema?

That is perhaps the No. 1 atopic dermatitis–related question that Lawrence F. Eichenfield, MD, fields from parents in his role as chief of pediatric and adolescent dermatology at Rady’s Children’s Hospital, San Diego.

The answer “is pretty tricky,” he said during MedscapeLive’s annual Las Vegas Dermatology Seminar. “We used to say, ‘yeah, your kid will probably outgrow the disease,’ but we now have good data that show there are variable courses.”

Using data from the birth study cohort known as the Avon Longitudinal Study of Parents and Children, researchers in the United Kingdom investigated the existence of different longitudinal phenotypes of AD among 9,894 children. They found that 58% of the children in the cohort were unaffected or had transient AD, while 12.9% had early-onset/early-resolving AD. The remaining AD phenotypes consisted of 7%-8% patients each (early-onset persistent, early-onset late-resolving, mid-onset resolving, and late-onset resolving).

“There have been several studies that looked at the natural course of AD,” said Dr. Eichenfield, distinguished professor of dermatology and pediatrics at the University of California, San Diego. “A cohort study from Thailand showed that 50% of patients with childhood AD lost their AD diagnosis about 5 years into it, while there was an increase in allergic rhino-conjunctivitis and asthma, similar to what’s been seen in atopic march studies,” he noted.

A separate group of investigators analyzed records from The Health Improvement Network in the UK to determine the prevalence of AD among more than 8 million patients seen in primary care between 1994 and 2013. They found that the cumulative lifetime prevalence of atopic eczema was 9.9% and the highest rates of active disease were among children and older adults. “The takeaway was markedly inconsistent in terms of whether AD went away over time or increased over time, so it’s really not especially helpful prevalence data,” Dr. Eichenfield said. “Overall, you have a high prevalence in the first years of life, it decreases, and it may increase again when people are 60 years and older. Whether that’s truly AD or xerotic eczema isn’t known in this data set.”

A separate meta-analysis of 17 studies reported that 26% of adults with AD said they had adult-onset disease, which is characterized by more atopy, more foot dermatitis, and less flexural involvement.

Dr. Eichenfield tells parents, “there’s a really good chance (depending on disease severity) that 60% to 70% of children will outgrow their eczema or most of it,” he said. “If you ask me when, I won’t tell you. The important thing is to treat it to minimize its impact. We want minimal rash, minimal itch, and minimal sleep disturbance. Sometimes I say, ‘that might improve the chance of the eczema getting better over time.’ ”

Following are four other common questions parents and patients ask him:

Can we figure out the allergies causing the eczema? “This is probably one of the most unnerving questions I get asked,” he said. “It’s a loaded question. My answer is that allergies are intertwined with AD. Searching for the secret allergy causing the atopic dermatitis is rarely successful.” Sensitization is much more common with AD, he added, meaning specific IgE testing, whether it be blood testing or skin prick testing. “The more severe your eczema is, the more chance you’ll have of real food allergy,” he said. “About 15% of milder eczema patients will have at least one food allergy, but when you get to the more moderate to severe cases, about 40% will have a true food allergy.”

Food reactions may not cause eczema, though. Food reactions can cause urticaria, angioedema, eczematous dermatitis, allergic contact dermatitis, contact urticaria, and respiratory findings. According to National Institutes of Health guidelines for food allergy, skin prick tests and serum IgE tests are recommended to assist in identification of foods that may be provoking IgE-mediated food reactions, but are not diagnostic of food allergy.

“There’s a huge literature showing that there’s a lot of food allergy testing that’s just not helpful,” he said. In one study, 89% of food challenges administered in patients who were listed as being allergic based on skin prick tests or serum IgE tests did not have a true food allergy.

“Empiric elimination diets aren’t especially useful. However, we occasionally see children who do have AD exacerbated by food allergies in the first year of life,” he said. NIH guidelines suggest that children younger than 5 years of age with moderate to severe AD be considered for food allergy evaluation for milk, egg, peanut, wheat, and soy, if at least one of the following conditions is met: the child has persistent AD in spite of optimized management and topical therapy, and/or the child has a reliable history of an immediate reaction after ingestion of a specific food.

“We do know that there are high rates of comorbid allergic processes, besides food allergy, associated with atopic dermatitis, including allergic rhinitis and asthma both in children and adults,” Dr. Eichenfield said. “I do discuss allergy triggers and their importance in the life of the individual, though not necessarily as factors in AD. There are a variety of environmental allergens and/or environmental triggers that can significantly impact AD. Recently, we have seen studies discussing air pollution and wildfires as exacerbators of AD.”

How should I bathe and moisturize? There are no standard guidelines for the frequency, type, or duration of bathing in patients with AD, he said, though in more severe disease, frequent bathing can be helpful along with standard anti-inflammatory topical medicines. “I keep my general recommendations vague,” Dr. Eichenfield said. “I do explain that we don’t want to use harsh soaps; we want to be gentle in our washing. I usually recommend daily to every other day bathing. It’s important to pat the skin dry and then apply a moisturizer. Applying a moisturizer 2-3 minutes after bathing is important and limited significant cleanser use can be helpful.”

Moisturizers and emollients are a standard of care in U.S. guidelines published in 2013 and 2014, and international guidelines, and are steroid-sparing and useful for both prevention and maintenance. “I tell parents and patients that there is no reason to avoid bathing because of AD as long as you moisturize after,” he said.

Do I have to use topical [name of drug]? “I try to explain that there is skin barrier dysfunction that stimulates the inflammatory milieu, and that inflammation in the skin or blood in AD negatively impacts skin barrier function,” Dr. Eichenfield said. “I explain that if inflammation doesn’t get better with good skin care, moisturizers, and avoidance of triggers, we need anti-inflammatory medication. Then we discuss what the options are, the significant variation in strengths of topical corticosteroids, and topical nonsteroid options.”

When he counsels parents and patients on the use of topical corticosteroids, he tells them that cortisone is a naturally-occurring metabolite, and that “we can work together to let you know how much medicine to use, and how a safe amount is a powerful tool to fix the eczema.” He often says that topical steroids “are like hammers. We have tiny hammers, like over-the-counter hydrocortisone, and sledgehammers like clobetasol. We also have ‘screwdrivers’ and ‘pliers’ with nonsteroidal topical calcineurin and PDE-4 inhibitors, which are especially useful for maintenance therapy. Topical ruxolitinib is a new medicine that we may use for patients as well. The label includes discussion of side effects from oral JAK inhibitors as well as from the drug development program, so it takes some time to talk through.”

Is it time for a stronger systemic medicine? Any conversation about this topic should support the concept that the AD is multifactorial. “We have the rash of eczema,” he said. “We have the itch. We have impact on sleep disturbance. We have the comorbidities. We have other physical changes, which can happen with bacterial infections and other immune system or cardiovascular changes. We have the impact on quality of life and impact on school and work. When we recognize that if patients have significant enough disease that it is not getting better with topicals and is having a negative impact on their lives, we can move our discussion to systemic therapy.”

When counseling patients about systemic therapy, Dr. Eichenfield will conduct a body surface area assessment and document how bad the itch is. “But I’m not just recording the information; I’m bringing it out in the room,” he said. “I’ll do a BSA assessment and say, for example, ‘oh, you have 32% of your body involved with eczema.’ I ask about sleep disturbance, to get the answer ‘out in the room.’ ” He also asks questions such as: “When was the last time your skin was last totally clear? Are there activities that you or your family don’t do because of your eczema, or that you’re living your life around it? Is there anxiety or depression?” Documenting both the impact on quality of life and the severity of disease “makes it easier to discuss systemic therapy,” Dr. Eichenfield said. “Meanwhile, as the provider, I am trying to figure out if the patient should ‘go into the topical therapy bucket’ or into the ‘systemic therapy bucket.’ ”

Counseling about systemic therapy includes shared decision-making regarding the choice of biologics versus oral JAK inhibitors versus traditional systemic agent or phototherapy. Factors to consider in the decision making include patient age, sex, severity, comorbidities, prior therapy, risk aversion, duration, medication access, and desired efficacy. “Evolving therapies can change the conversation, the questions, and the outcomes, but the overarching desired outcome is long-term disease control, minimal eczematous rash, minimal pruritus, and minimal sleep disturbance,” he said.

Patients with cardiac implantable electronic devices (CIEDs) who received treatment with an sodium-glucose cotransporter 2 inhibitor had significantly fewer atrial arrhythmia events, compared with those who never received such a drug, in a prospective analysis of nearly 14,000 patients with a device who were followed for an average of nearly 2 years.

The findings suggest that use of an agent from the class of SGLT2 inhibitors “is associated with a pronounced reduction in atrial arrhythmia burden and all-cause mortality in patients with a CIED in a real-world setting,” said Ilan Goldenberg, MD, at the American Heart Association scientific sessions. “These data indicate possible antiarrhythmic properties of SGLT2 inhibitors that are incremental to the beneficial effects of the drug on heart failure outcomes,” added Dr. Goldenberg, director of the Clinical Cardiovascular Research Center at the University of Rochester (N.Y.).

In a propensity score–matched analysis that included more than 5,000 of the enrolled patients with a CIED, treatment with an SGLT2 inhibitor was tied to a significant 23% relative reduction in atrial arrhythmia events and a 44% relative drop in all-cause death, he reported.
 

Effect mediated by reduced left atrial pressure?

“Other heart failure drugs have shown some decrease in the rate of sudden cardiac death, but this is the first [heart failure] drug to associate with a reduction in atrial arrhythmias,” Dr. Goldenberg noted. “We think that a reduction in left atrial pressure” produced by treatment with an SGLT2 inhibitor “may be linked to the reduction in atrial arrhythmias.”

The study did not show an association of SGLT2-inhibitor use and a change in ventricular arrhythmias, compared with patients with CIEDs who did not receive an agent from this class.

The findings suggest “expanding the possible indications for SGLT2 inhibitors,” commented Harriette G.C. Van Spall, MD, a cardiologist at McMaster University, Hamilton, Ont., who moderated the session where Dr. Goldenberg gave his report.

The study included 13,890 consecutive, prospectively enrolled patients who received a CIED during January 2015–April 2020 at any of five hospitals operated by either of two tertiary health care systems, one run by the University of Rochester and the second based at Sheba Medical Center in Tel HaShomer, Israel. The devices that made patients eligible for the study included permanent pacemakers, implantable cardioverter defibrillators, cardiac resynchronization therapy devices, and implantable cardiac monitors. A blinded adjudication committee composed of electrophysiologists identified the arrhythmic episodes.

At entry into the study (the time of device implantation), 12,992 patients were not receiving an SGLT2 inhibitor (94%) and 898 (6%) were receiving a drug from this class. Of those, 39% were on dapagliflozin (Farxiga), 35% were on empagliflozin (Jardiance), and 26% were on canagliflozin (Invokana).

Patients receiving an SGLT2 inhibitor at baseline were on average substantially younger than the patients not on this drug class (59 years vs. 69 years); they had a substantially higher prevalence of diabetes (78% vs. 25%), and ischemic cardiomyopathy (63% vs. 39%). Patients on an SGLT2 inhibitor at baseline also had more modestly higher prevalence rates of prior heart failure (38% vs. 31%), and hypertension (69% vs. 63%). Prevalence of a history of atrial fibrillation (AFib) was nearly the same in both groups: 31% in patients on an SGLT2 inhibitor and 35% in those not on these drugs.

The study’s primary endpoint was the total number of arrhythmia events during follow-up of 24,442 patient-years, during which patients exhibited 19,633 atrial arrhythmia events and 3,231 ventricular arrhythmia events.
 

1% absolute reduction in atrial arrhythmias

A multivariate analysis of the entire population – adjusted for baseline differences in age, diabetes, sex, and history of AFib – showed that treatment with an SGLT2 inhibitor at baseline was linked with a significant 24% relative reduction in incident atrial arrhythmia events, a significant 24% reduction in both atrial and ventricular arrhythmia events, and a 42% relative reduction in all-cause deaths, compared with no SGLT2-inhibitor treatment.

The only analyzed endpoint that showed no significant between-group difference was incidence of ventricular arrhythmias, which was a relative 7% lower in the SGLT2-inhibitor group.

On an absolute basis, treatment with an SGLT2 inhibitor was tied to about a 1% lower rate of atrial arrhythmia events per year, a reduction from a 2.5% rate in those not on an SGLT2 inhibitor to about a 1.5% rate in those taking this drug class.

A second, confirmatory analysis used propensity score matching to identify 5,323 patients not on an SGLT2 inhibitor at baseline who closely matched the 898 patients on an SGLT2 inhibitor. The multivariate modeling for this analysis also adjusted for age, diabetes, sex, and history of AFib.

The results of these analyses closely matched the calculations that used the entire study population. Relative to patients not on an SGLT2 inhibitor those on a drug from this class had 23% fewer atrial arrhythmias, 44% fewer total death, and 22% fewer atrial or ventricular arrhythmias, all significant differences. However, ventricular arrhythmias only reduced by a relative 5%, a nonsignificant difference.

In the propensity score–matched analysis, the absolute reduction in atrial arrhythmias in those on an SGLT2 inhibitor at baseline was roughly 1.3% fewer per year, compared with those not on this drug class.

The study was funded by an unrestricted grant to the University of Rochester from AstraZeneca, the company that markets the SGLT2 inhibitor dapagliflozin (Farxiga). Dr. Goldenberg and Dr. Van Spall had no disclosures.

Patients with cardiac implantable electronic devices (CIEDs) who received treatment with an sodium-glucose cotransporter 2 inhibitor had significantly fewer atrial arrhythmia events, compared with those who never received such a drug, in a prospective analysis of nearly 14,000 patients with a device who were followed for an average of nearly 2 years.

The findings suggest that use of an agent from the class of SGLT2 inhibitors “is associated with a pronounced reduction in atrial arrhythmia burden and all-cause mortality in patients with a CIED in a real-world setting,” said Ilan Goldenberg, MD, at the American Heart Association scientific sessions. “These data indicate possible antiarrhythmic properties of SGLT2 inhibitors that are incremental to the beneficial effects of the drug on heart failure outcomes,” added Dr. Goldenberg, director of the Clinical Cardiovascular Research Center at the University of Rochester (N.Y.).

In a propensity score–matched analysis that included more than 5,000 of the enrolled patients with a CIED, treatment with an SGLT2 inhibitor was tied to a significant 23% relative reduction in atrial arrhythmia events and a 44% relative drop in all-cause death, he reported.
 

Effect mediated by reduced left atrial pressure?

“Other heart failure drugs have shown some decrease in the rate of sudden cardiac death, but this is the first [heart failure] drug to associate with a reduction in atrial arrhythmias,” Dr. Goldenberg noted. “We think that a reduction in left atrial pressure” produced by treatment with an SGLT2 inhibitor “may be linked to the reduction in atrial arrhythmias.”

The study did not show an association of SGLT2-inhibitor use and a change in ventricular arrhythmias, compared with patients with CIEDs who did not receive an agent from this class.

The findings suggest “expanding the possible indications for SGLT2 inhibitors,” commented Harriette G.C. Van Spall, MD, a cardiologist at McMaster University, Hamilton, Ont., who moderated the session where Dr. Goldenberg gave his report.

The study included 13,890 consecutive, prospectively enrolled patients who received a CIED during January 2015–April 2020 at any of five hospitals operated by either of two tertiary health care systems, one run by the University of Rochester and the second based at Sheba Medical Center in Tel HaShomer, Israel. The devices that made patients eligible for the study included permanent pacemakers, implantable cardioverter defibrillators, cardiac resynchronization therapy devices, and implantable cardiac monitors. A blinded adjudication committee composed of electrophysiologists identified the arrhythmic episodes.

At entry into the study (the time of device implantation), 12,992 patients were not receiving an SGLT2 inhibitor (94%) and 898 (6%) were receiving a drug from this class. Of those, 39% were on dapagliflozin (Farxiga), 35% were on empagliflozin (Jardiance), and 26% were on canagliflozin (Invokana).

Patients receiving an SGLT2 inhibitor at baseline were on average substantially younger than the patients not on this drug class (59 years vs. 69 years); they had a substantially higher prevalence of diabetes (78% vs. 25%), and ischemic cardiomyopathy (63% vs. 39%). Patients on an SGLT2 inhibitor at baseline also had more modestly higher prevalence rates of prior heart failure (38% vs. 31%), and hypertension (69% vs. 63%). Prevalence of a history of atrial fibrillation (AFib) was nearly the same in both groups: 31% in patients on an SGLT2 inhibitor and 35% in those not on these drugs.

The study’s primary endpoint was the total number of arrhythmia events during follow-up of 24,442 patient-years, during which patients exhibited 19,633 atrial arrhythmia events and 3,231 ventricular arrhythmia events.
 

1% absolute reduction in atrial arrhythmias

A multivariate analysis of the entire population – adjusted for baseline differences in age, diabetes, sex, and history of AFib – showed that treatment with an SGLT2 inhibitor at baseline was linked with a significant 24% relative reduction in incident atrial arrhythmia events, a significant 24% reduction in both atrial and ventricular arrhythmia events, and a 42% relative reduction in all-cause deaths, compared with no SGLT2-inhibitor treatment.

The only analyzed endpoint that showed no significant between-group difference was incidence of ventricular arrhythmias, which was a relative 7% lower in the SGLT2-inhibitor group.

On an absolute basis, treatment with an SGLT2 inhibitor was tied to about a 1% lower rate of atrial arrhythmia events per year, a reduction from a 2.5% rate in those not on an SGLT2 inhibitor to about a 1.5% rate in those taking this drug class.

Intrauterine contraceptive devices (IUDs) have been linked to increased background enhancement on breast MRI, according to research presented at the Radiological Society of North America 2021 annual meeting.

About 10.4% of women 15-49 years of age who use contraception have an IUD or contraceptive implant, according to the Centers for Disease Control and Prevention. Unlike oral or transdermal hormonal contraceptives and hormone replacement therapy, levonorgestrel-releasing IUDs release a small amount of the hormone directly into the uterus and are thought to have a much more localized effect, Luisa Huck, MD, the lead author of the study, said in an interview.

But women with IUDs have long reported adverse effects associated with other hormonal medication. “In the past, some women reported depression, headaches, sleep disorders, and panic attacks,” noted Dr. Huck, a radiology resident at RWTH Aachen University in Germany.

Christiane Kuhl, MD, chief of the department of radiology at RWTH Aachen University and senior author of the research, had also observed that women with hormonal IUDs often have increased background parenchymal enhancement (BPE) on contrast-enhanced MRI. BPE “has been established as a sensitive marker of hormonal stimulation of breast,” the study authors wrote, and previous studies have shown that women using hormonal medications have higher BPE on breast MRIs.

To better understand whether IUDs can increase BPE, Dr. Huck and colleagues used the hospital database to search for premenopausal women who had undergone breast MRIs for screening between January 2014 and July 2020. To be included, women had to have had at least two scans: one with and one without an IUD in place, with the scan conducted at least 4 weeks after IUD placement or removal. All women in the study had no history of breast cancer or hormone or antihormone intake.

The study involved 48 women with an average age of 45 years and a median of 27 months between the two scans. Forty-six of the women had the Mirena levonorgestrel-releasing IUD and two had the Jaydess IUD. To account for hormone variations between patients, the researchers used each patient as their own reference point. To control for age-related effects, 25 women had their first MRI without an IUD and their second scan with an IUD in place. The second group of 23 women underwent their first MRI with an IUD and had it removed before the second scan.

Hormonal effects on breast enhancement are very complex, and hormonal stimulation is not always predictably correlated with changes on MRI imaging.

For 23 women in the study, background enhancement was higher on scans with the IUD than without (P < .001). For 24 women, there was no change in BPE with or without an IUD, and one woman had lower BPE with an IUD than without.

“It is very interesting and relevant to practice to consider that the presence of an intrauterine device would have potential impact on the enhancement we see in the breast on MRI imaging,” Samantha Heller, MD, PhD, associate professor of radiology at New York University, said in an interview.

However, the study used BPE as a measure for hormonal shifts, and “hormonal effects on breast enhancement are very complex, and hormonal stimulation is not always predictably correlated with changes on MRI imaging,” she noted. BPE on MRI can fluctuate, so testing actual hormone levels in patients with elevated BPE could be helpful to identify hormonal shifts, she added. It is also important to understand why half of the women in the study showed no variation in BPE, she said.

The study findings are not very surprising, considering that it is known that low levels of progesterone from IUDs circulate in the blood stream, Frances Casey, MD, MPH, associate professor in the department of obstetrics and gynecology at Virginia Commonwealth University in Richmond, said in an interview. They do not suggest that there should be any changes to IUD guidelines, she added.

However, “the study findings raise the question as to whether IUD status should be documented as a matter of course prior to performing breast MRI,” said Dr. Heller. “It is standard to document the timing of a woman’s menstrual cycle, as well as to note any hormone suppression or replacement therapy. This is in part so that the radiologist may understand the etiology of any observed variation in background enhancement,” she explained.

Although increased enhancement on MRI has sometimes been linked to higher chances of recommendations for additional imaging or biopsies, she noted, “more work would be needed to understand the impact – if any – of an IUD on breast MRI recommendations due to enhancement changes.”

Dr. Huck, Dr. Heller, and Dr. Casey disclosed no relevant financial relationships.

The San Antonio Breast Cancer Symposium (SABCS) 2021 will “be a great meeting,” according to Carlos Arteaga, MD, director of Simmons Comprehensive Cancer Center at UT Southwestern Medical Center, Dallas.

Dr. Arteaga, the meeting’s codirector, said the first-ever hybrid symposium will take place virtually from Dec. 7 to 10 as well as in person. Online availability appears to be a boon to attendance, with a record 9,325 registrants for the 2020 symposium, held only virtually because of the COVID-19 pandemic.

The meeting will have an app available, which can be accessed by searching “San Antonio Breast Cancer Symposium” (Google Play for Android, Apple for iOS) and downloading, or by going to www.core-apps.com/dl/sabcs from a desktop computer.

Dr. Arteaga provided a sneak peek of the most exciting research being presented at the upcoming meeting.
 

On the horizon for advanced breast cancer

A “very important” study of an investigational oral agent employed in heavily pretreated postmenopausal women with estrogen receptor–positive (ER+) advanced breast cancer headlines the meeting.

This international, multicenter trial could have “practice-changing implications,” Dr. Arteaga said in an interview.

The phase 3 EMERALD trial (abstract GS2-02) pits elacestrant, a selective estrogen receptor degrader (SERD), against standard endocrine therapy (fulvestrant or an aromatase inhibitor) in patients with metastatic breast cancer whose disease has progressed after treatment with at least one endocrine therapy and a CDK4/6 inhibitor.

The trial is important because many patients with breast cancer have estrogen receptor mutations, which are a “major mechanism of [drug] resistance” and thus progression on earlier therapy, Dr. Arteaga said.

Elacestrant is in good company among a plethora of oral SERDs under investigation in advanced breast cancer; however, currently, fulvestrant – which requires an intramuscular injection in the buttocks every month – is the only approved SERD.

“There’s plenty of preclinical data that suggest that these drugs [SERDs] may have activity against these mutant forms of the receptor, which occur in up to 40% of patients with advanced ER+ breast cancer,” he explained.

Researchers will present data on two primary outcome measures from the phase 3 trial: progression-free survival (PFS) based on mutations of the estrogen receptor 1 gene (ESR1-mut) and PFS in all subjects regardless of ESR1 status.

In addition to the EMERALD trial, PADA-1 (abstract GS3-05) is another important randomized, phase 3 trial focused on treating estrogen receptor mutations in patients with metastatic disease, said Dr. Arteaga.

The trial has enrolled patients with ER+ metastatic breast cancer who received an aromatase inhibitor (letrozole, anastrozole, or exemestane) and the CDK4/6 inhibitor palbociclib as first-line therapy.

In step 1 of the trial, approximately 1,000 patients were screened for circulating blood ESR1 mutation detection at regular intervals while being treated with palbociclib and an aromatase inhibitor in a continuous scheme until tumor progression or ESR1 mutation detection.

In step 2, up to 200 patients with a rising circulating ESR1 mutation and no tumor progression were randomized 1:1 to no change in therapy until tumor progression or to receive palbociclib plus fulvestrant until tumor progression.

The trial examines the safety and efficacy of “a clinical conundrum that we face” in this setting: whether or not to switch treatment from an aromatase inhibitor to fulvestrant while continuing a CDK4/6 inhibitor at the sign of mutation detection, Dr. Arteaga explained.
 

Refining who gets the ‘kitchen sink’

Dr. Arteaga highlighted two trials focused on the immune checkpoint inhibitor pembrolizumab.

The phase 3 KEYNOTE-522 study led to the approval of neoadjuvant pembrolizumab plus chemotherapy for early-stage triple-negative breast cancer (TNBC) in July 2021. At this year’s SABCS, researchers will present new data from KEYNOTE-522 (abstract GS1-01), representing final results from the trial’s event-free survival (EFS) outcome.

Previously, investigators reported a statistically significant and clinically meaningful improvement in EFS. These data suggest “that deploying immunotherapy early before surgery ... may be curative in some patients,” Dr. Arteaga said. The new data will allow the “robustness and consistency” of the earlier findings to be assessed.

But, he added, this is a “tough” treatment, which includes five drugs. “It’s the kitchen sink, and not everybody needs the kitchen sink. It’s important to refine these findings. Some patients may not need pembrolizumab, but some do.”

The second trial exploring pembrolizumab – KEYNOTE-355 (abstract GS1-02) – mirrors KEYNOTE-522 but in patients with previously untreated locally recurrent inoperable or metastatic TNBC whose tumors expressed PD-L1.

Previously, investigators reported that pembrolizumab combined with chemotherapy showed statistically significant improvements in overall survival and PFS compared to placebo plus chemotherapy. At the 2021 SABCS, researchers will provide final study results, including outcomes in subgroups of patients by additional combined positive score cutoffs.
 

Metformin trial: ‘This is it’

Dr. Arteaga highlighted CCTGMA.32 (abstract GS1-08), a phase 3 randomized, placebo-controlled adjuvant trial of the diabetes drug metformin versus placebo in early breast cancer. Results of the primary efficacy analysis of the trial will be presented at the meeting.

The Canadian-led study seeks to determine if metformin can decrease breast cancer cell growth and work with cancer therapies to prevent disease recurrence. The study design calls for patients to take twice-daily oral metformin or placebo pills for up to 5 years in the absence of disease progression.

The primary outcome of the 3,500-plus patient trial is invasive disease-free survival in hormone receptor (ER and PgR) negative and positive (ER and/or PgR) subgroups.

“Metformin has actually been associated with improved survival [in breast cancer] in patients on chemotherapy. But we don’t know exactly how,” he said. “There’s never been a head-to-head comparison in the adjuvant setting [before]. This is it.”
 

TKI for breast cancer with brain mets

The SABCS codirector spotlighted an updated overall survival analysis of the randomized phase 3 PHOEBE trial (abstract GS3-02).

Previous research confirmed the superiority of pyrotinib, a novel TKI targeting HER1, HER2, and HER4, over lapatinib when given in combination with capecitabine in HER2-positive metastatic breast cancer.

In the United States, the lapatinib-capecitabine combination is “mostly used” in patients with HER2 metastatic disease and brain metastases who also undergo stereotactic radiation, Dr. Arteaga said.

This use has continued despite groundbreaking results from the HER2CLIMB trial, featuring the TKI tucatinib, he said.

As reported last year, adding tucatinib to trastuzumab and capecitabine in patients with HER2-positive breast cancer and brain metastases increased median overall survival from 12 months to 18.1 months. The results were called the first of their kind at that time.

The pyrotinib study may matter to American clinicians because pyrotinib is used mostly in China, not the United States, and this analysis suggests that pyrotinib could be part of the armamentarium in the United States, alongside tucatinib.

TKIs are like Coke and Pepsi, Dr. Arteaga said: “Similar but not identical.” Therefore, it is worth taking a look at the new study, he said. “There may be some benefit in having more than one [TKI] in the therapeutic armamentarium.”

The San Antonio Breast Cancer Symposium (SABCS) 2021 will “be a great meeting,” according to Carlos Arteaga, MD, director of Simmons Comprehensive Cancer Center at UT Southwestern Medical Center, Dallas.

Dr. Arteaga, the meeting’s codirector, said the first-ever hybrid symposium will take place virtually from Dec. 7 to 10 as well as in person. Online availability appears to be a boon to attendance, with a record 9,325 registrants for the 2020 symposium, held only virtually because of the COVID-19 pandemic.

The meeting will have an app available, which can be accessed by searching “San Antonio Breast Cancer Symposium” (Google Play for Android, Apple for iOS) and downloading, or by going to www.core-apps.com/dl/sabcs from a desktop computer.

Dr. Arteaga provided a sneak peek of the most exciting research being presented at the upcoming meeting.
 

On the horizon for advanced breast cancer

A “very important” study of an investigational oral agent employed in heavily pretreated postmenopausal women with estrogen receptor–positive (ER+) advanced breast cancer headlines the meeting.

This international, multicenter trial could have “practice-changing implications,” Dr. Arteaga said in an interview.

The phase 3 EMERALD trial (abstract GS2-02) pits elacestrant, a selective estrogen receptor degrader (SERD), against standard endocrine therapy (fulvestrant or an aromatase inhibitor) in patients with metastatic breast cancer whose disease has progressed after treatment with at least one endocrine therapy and a CDK4/6 inhibitor.

The trial is important because many patients with breast cancer have estrogen receptor mutations, which are a “major mechanism of [drug] resistance” and thus progression on earlier therapy, Dr. Arteaga said.

Elacestrant is in good company among a plethora of oral SERDs under investigation in advanced breast cancer; however, currently, fulvestrant – which requires an intramuscular injection in the buttocks every month – is the only approved SERD.

“There’s plenty of preclinical data that suggest that these drugs [SERDs] may have activity against these mutant forms of the receptor, which occur in up to 40% of patients with advanced ER+ breast cancer,” he explained.

Researchers will present data on two primary outcome measures from the phase 3 trial: progression-free survival (PFS) based on mutations of the estrogen receptor 1 gene (ESR1-mut) and PFS in all subjects regardless of ESR1 status.

In addition to the EMERALD trial, PADA-1 (abstract GS3-05) is another important randomized, phase 3 trial focused on treating estrogen receptor mutations in patients with metastatic disease, said Dr. Arteaga.

The trial has enrolled patients with ER+ metastatic breast cancer who received an aromatase inhibitor (letrozole, anastrozole, or exemestane) and the CDK4/6 inhibitor palbociclib as first-line therapy.

In step 1 of the trial, approximately 1,000 patients were screened for circulating blood ESR1 mutation detection at regular intervals while being treated with palbociclib and an aromatase inhibitor in a continuous scheme until tumor progression or ESR1 mutation detection.

In step 2, up to 200 patients with a rising circulating ESR1 mutation and no tumor progression were randomized 1:1 to no change in therapy until tumor progression or to receive palbociclib plus fulvestrant until tumor progression.

The trial examines the safety and efficacy of “a clinical conundrum that we face” in this setting: whether or not to switch treatment from an aromatase inhibitor to fulvestrant while continuing a CDK4/6 inhibitor at the sign of mutation detection, Dr. Arteaga explained.
 

Refining who gets the ‘kitchen sink’

Dr. Arteaga highlighted two trials focused on the immune checkpoint inhibitor pembrolizumab.

The phase 3 KEYNOTE-522 study led to the approval of neoadjuvant pembrolizumab plus chemotherapy for early-stage triple-negative breast cancer (TNBC) in July 2021. At this year’s SABCS, researchers will present new data from KEYNOTE-522 (abstract GS1-01), representing final results from the trial’s event-free survival (EFS) outcome.

Previously, investigators reported a statistically significant and clinically meaningful improvement in EFS. These data suggest “that deploying immunotherapy early before surgery ... may be curative in some patients,” Dr. Arteaga said. The new data will allow the “robustness and consistency” of the earlier findings to be assessed.

But, he added, this is a “tough” treatment, which includes five drugs. “It’s the kitchen sink, and not everybody needs the kitchen sink. It’s important to refine these findings. Some patients may not need pembrolizumab, but some do.”

The second trial exploring pembrolizumab – KEYNOTE-355 (abstract GS1-02) – mirrors KEYNOTE-522 but in patients with previously untreated locally recurrent inoperable or metastatic TNBC whose tumors expressed PD-L1.

Previously, investigators reported that pembrolizumab combined with chemotherapy showed statistically significant improvements in overall survival and PFS compared to placebo plus chemotherapy. At the 2021 SABCS, researchers will provide final study results, including outcomes in subgroups of patients by additional combined positive score cutoffs.
 

Metformin trial: ‘This is it’

Dr. Arteaga highlighted CCTGMA.32 (abstract GS1-08), a phase 3 randomized, placebo-controlled adjuvant trial of the diabetes drug metformin versus placebo in early breast cancer. Results of the primary efficacy analysis of the trial will be presented at the meeting.

The Canadian-led study seeks to determine if metformin can decrease breast cancer cell growth and work with cancer therapies to prevent disease recurrence. The study design calls for patients to take twice-daily oral metformin or placebo pills for up to 5 years in the absence of disease progression.

The primary outcome of the 3,500-plus patient trial is invasive disease-free survival in hormone receptor (ER and PgR) negative and positive (ER and/or PgR) subgroups.

“Metformin has actually been associated with improved survival [in breast cancer] in patients on chemotherapy. But we don’t know exactly how,” he said. “There’s never been a head-to-head comparison in the adjuvant setting [before]. This is it.”
 

TKI for breast cancer with brain mets

The SABCS codirector spotlighted an updated overall survival analysis of the randomized phase 3 PHOEBE trial (abstract GS3-02).

Previous research confirmed the superiority of pyrotinib, a novel TKI targeting HER1, HER2, and HER4, over lapatinib when given in combination with capecitabine in HER2-positive metastatic breast cancer.

In the United States, the lapatinib-capecitabine combination is “mostly used” in patients with HER2 metastatic disease and brain metastases who also undergo stereotactic radiation, Dr. Arteaga said.

This use has continued despite groundbreaking results from the HER2CLIMB trial, featuring the TKI tucatinib, he said.

As reported last year, adding tucatinib to trastuzumab and capecitabine in patients with HER2-positive breast cancer and brain metastases increased median overall survival from 12 months to 18.1 months. The results were called the first of their kind at that time.

The pyrotinib study may matter to American clinicians because pyrotinib is used mostly in China, not the United States, and this analysis suggests that pyrotinib could be part of the armamentarium in the United States, alongside tucatinib.

TKIs are like Coke and Pepsi, Dr. Arteaga said: “Similar but not identical.” Therefore, it is worth taking a look at the new study, he said. “There may be some benefit in having more than one [TKI] in the therapeutic armamentarium.”

Dr. Arteaga receives or has received grant support from Pfizer and Lilly and serves or has served in a scientific advisory role with Novartis, Lilly, TAIHO Oncology, Daiichi Sankyo, Merck, AstraZeneca, OrigiMed, Immunomedics, ARVINAS, Sanofi, Athenex, and the Susan G.

According to Iltefat H. Hamzavi, MD, the initial clinical assessment for hidradenitis suppurativa (HS) includes posing two questions to patients: Have you had outbreaks of boils during the past 6 months? Where and how many boils have you had?

If the answer to the first question is “yes” and the patient has had at least two boils in intertriginous areas, that person likely has HS, a disease of apocrine gland–bearing skin that occurs in 1%-4% of people, has a higher prevalence in Blacks, compared with Whites, and affects more women than men by a 3:1 ratio.

“Current treatments offer limited efficacy, and the disease is chronic and recurrent,” Dr. Hamzavi, of the department of dermatology at Henry Ford Health System, Detroit, said during MedscapeLive’s annual Las Vegas Dermatology Seminar. “You often see nodules, abscesses, fistulae, and scarring,” with all different skin types represented in the majority of patients.

Typical HS lesions appear as inflamed nodules, abscesses, draining fistulas, and scars as well as double-headed “tombstone” comedones, he said. These are typically located in the axilla, intermammary folds, in the groin, around the genitals, and on the buttocks. Atypical lesions can also occur – often folliculitis and open comedones in locations such as the waistline, the neck, and behind the ears.

The differential diagnosis is wide-ranging and includes bacterial abscess, inflamed cyst, folliculitis, pilonidal sinus, cellulitis, and cutaneous Crohn’s disease. Pain may appear out of proportion to the physical examination.

“There is a window of opportunity to treat HS, early in the disease process,” Dr. Hamzavi said. “There are no definitive cures for HS but lots of treatment options.”

According to clinical management guidelines published by the United States and Canadian Hidradenitis Suppurativa Foundations, options for moderate stage disease include antibiotics, antiandrogens, retinoids, immunosuppression/biologics, deroofing, and limited excision with primary closure. Options for severe disease include radical excision.

“HS requires a mix of medical and procedural treatments based on the number of nodules,” Dr. Hamzavi said. “Because the disease has so many different phases, there is no perfect outcome measure yet, but progress is being made.”

In 2018, an effort to develop a consensus core outcome set of domains regarding what to measure in clinical trials of HS was launched; it is known as the Hidradenitis Suppurativa Core Outcomes Set International Collaboration (HISTORIC). It was formed as a collaboration between the International Dermatology Outcome Measures (IDEOM) initiative, the Cochrane Skin Group – Core Outcome Set Initiative (CSG-COUSIN), and Zealand University Hospital, Roskilde.

HISTORIC is now part of the partnership with CSG-COUSIN and this work continues onward. Core domains as defined by the group include pain, physical signs, HS-specific quality of life, global assessment, and disease progression. “For now, we are mostly using some objective measures and some patient-reported outcomes with the addition of ultrasound in some centers,” Dr. Hamzavi said.

He underscored the importance of lifestyle modifications in patients with HS, including smoking cessation and weight loss, as well as decreasing pressure/friction on lesions, using warm compresses, and modifying diet. “This generally involves a low-inflammatory diet: Low carbohydrate, low dairy, and higher protein content, but there is much work needed to understand the role of diet in HS,” he said.

“This is a tough disease, but the compassion you offer these patients will be paid back to you a thousandfold. They tend to be some of the happiest and most appreciative patients you will ever have in your practice.”

Dr. Hamzavi disclosed that he has been a clinical investigator for Clinuvel, Incyte, Pfizer, Avita, and Ferndale Labs. He has also been a consultant for Pfizer, AbbVie, Novartis, and Aclaris, and has received a grant from Estee Lauder.

The investigational PCSK9 inhibitor that Merck showcased recently would be more than a “me-too” drug if it ultimately wins approval, despite competition from several approved agents that slash elevated cholesterol levels by targeting the same protein.

BananaStock/thinkstockphotos.com

In fact, it would be something of a breakthrough. The new agent under study – now called MK-0616 – comes in pill form, in contrast to the three currently available PCSK9-lowering drugs that must be given in injections separated by weeks to months.

The drug faces an uncertain road to regulatory review and any approval, but MK-0616 at least seems to be starting out in the right direction.

In two phase 1 studies with a total of 100 participants, plasma PCSK9 levels plunged more than 90% after a single dose of the drug; and low-density-lipoprotein cholesterol (LDL-C) levels dropped about 65% when MK-0616 was given daily for 2 weeks on a background of statin therapy.

Moreover, “MK-0616 was generally well tolerated at up to and including single doses of 300 milligrams,” the maximum tested in the studies, Douglas G. Johns, PhD, reported at the virtual American Heart Association scientific sessions.

The collective results from the oral agent’s earliest human experience are “definitely encouraging” and support MK-0616 as a potential LDL-lowering agent that would be more convenient and arguably more accessible to patients compared to current injectable PCSK9 inhibitors, proposed Dr. Johns, clinical director of translational medicine for Merck in Kenilworth, N.J.

Available PCSK9-targeting agents include alirocumab (Praluent, Sanofi/Regeneron), Food and Drug Administration–approved in July 2015, and evolocumab (Repatha, Amgen), approved by the agency the following month. Both are monoclonal antibodies with neutralizing specificity for the PCSK9 protein; whereas the third such agent, inclisiran (Leqvio, Novartis) is a small-molecule interfering-RNA that suppresses PCSK9 synthesis. Inclisiran is approved in the European Union but its case to the FDA was turned down in 2020.

Dr. Johns said MK-0616 is a cyclic peptide that is “about one-hundredth the size of a monoclonal antibody, but we’re able to achieve monoclonal antibody-like potency and selectivity with this much smaller footprint.”

Added to statin therapy, the current PCSK9-targeting agents reduce LDL-C by an additional one-half or more, and the two antibody-based agents “also decrease atherosclerotic cardiovascular events. They are, however, expensive and not always available, requiring insurance or other approval,” observed Anne C. Goldberg, MD, as invited discussant after Dr. Johns’ presentation.

“They require every 2- to 4-week injections. They’re generally reserved for secondary prevention, and sometimes primary prevention as in familial hypercholesterolemia,” said Dr. Goldberg, of Washington University, St. Louis. Inclisiran, she noted, requires injections every 6 months and has yet to show its mettle in cardiovascular outcomes trials.

“Certainly, an oral form would be easier to use,” she said. “This would be particularly helpful in patients averse to injections,” especially, perhaps, in children. “Children with familial hypercholesterolemia could benefit with greater cholesterol lowering and might be better off with a pill than an injection.” That would be good reason to emphasize the enrollment of children in the drug’s upcoming clinical trials, Dr. Goldberg said.

But cost could potentially become restrictive for MK-0616 as well, should it ever be approved. “If it’s priced too high, then are you really going to see the increased use?” she posed. “Certainly, there’s a high bar for therapies that are add-on to statins in terms of cost effectiveness.”

In the first of the two trials, 60 predominantly White male participants aged 50 or younger were randomly assigned to receive a single dose of MK-0616, at different levels ranging from 10 mg to 300 mg, or placebo. They subsequently crossed over to a different group for a second round of dosing. Both times, three participants took the drug for every one who received placebo.

Participants who took the active drug, regardless of dosage, showed greater than 90% reductions in circulating PCSK9 levels compared to baseline. Six participants discontinued the study before its completion.

In the second trial, 40 White adults aged 65 or younger (mean, 58), including 13 women, with LDL-C of 60 mg/dL to 160 mg/dL (mean, 87 mg/dL) on statin therapy for at least 3 months were randomly assigned 3-to-1 to add-on MK-0616, either 10 mg or 20 mg daily, or placebo for 14 days.

LDL-C levels fell an average of about 65% over the 2 weeks among those taking the active drug; they declined less than 5% for those who took placebo.

There were no deaths or serious adverse events in either trial, Dr. Johns reported. On the other hand, pharmacokinetics studies showed that exposure to the drug fell by “about 50%-60%” when dosing was preceded by food intake within the previous 30 minutes. “However, if a meal is consumed 30 minutes after the dose, this food effect is much, much less prominent, almost negligible.”

These preliminary results show the drug is “orally bioavailable and exerts a clinically meaningful effect,” Dr. Johns said. “However, there’s definitely more to be done. And we are planning the next phase of clinical development, a phase 2 trial, sometime next year.”

The research was funded by Merck. Dr. Johns disclosed employment with and equity ownership in Merck, as did all the study’s coauthors. Dr. Goldberg disclosed holding research contracts through her institution with Regeneron/Sanofi-Aventis, Amarin, Amgen, Pfizer, IONIS/Akcea, Regeneron, Novartis, Arrowroot Pharmaceuticals, and the FH Foundation; and consulting for Novartis, Akcea, Regeneron, and Esperion.

In two phase 1 studies with a total of 100 participants, plasma PCSK9 levels plunged more than 90% after a single dose of the drug; and low-density-lipoprotein cholesterol (LDL-C) levels dropped about 65% when MK-0616 was given daily for 2 weeks on a background of statin therapy.

Moreover, “MK-0616 was generally well tolerated at up to and including single doses of 300 milligrams,” the maximum tested in the studies, Douglas G. Johns, PhD, reported at the virtual American Heart Association scientific sessions.

The collective results from the oral agent’s earliest human experience are “definitely encouraging” and support MK-0616 as a potential LDL-lowering agent that would be more convenient and arguably more accessible to patients compared to current injectable PCSK9 inhibitors, proposed Dr. Johns, clinical director of translational medicine for Merck in Kenilworth, N.J.

Available PCSK9-targeting agents include alirocumab (Praluent, Sanofi/Regeneron), Food and Drug Administration–approved in July 2015, and evolocumab (Repatha, Amgen), approved by the agency the following month. Both are monoclonal antibodies with neutralizing specificity for the PCSK9 protein; whereas the third such agent, inclisiran (Leqvio, Novartis) is a small-molecule interfering-RNA that suppresses PCSK9 synthesis. Inclisiran is approved in the European Union but its case to the FDA was turned down in 2020.

Dr. Johns said MK-0616 is a cyclic peptide that is “about one-hundredth the size of a monoclonal antibody, but we’re able to achieve monoclonal antibody-like potency and selectivity with this much smaller footprint.”

Added to statin therapy, the current PCSK9-targeting agents reduce LDL-C by an additional one-half or more, and the two antibody-based agents “also decrease atherosclerotic cardiovascular events. They are, however, expensive and not always available, requiring insurance or other approval,” observed Anne C. Goldberg, MD, as invited discussant after Dr. Johns’ presentation.

“They require every 2- to 4-week injections. They’re generally reserved for secondary prevention, and sometimes primary prevention as in familial hypercholesterolemia,” said Dr. Goldberg, of Washington University, St. Louis. Inclisiran, she noted, requires injections every 6 months and has yet to show its mettle in cardiovascular outcomes trials.

“Certainly, an oral form would be easier to use,” she said. “This would be particularly helpful in patients averse to injections,” especially, perhaps, in children. “Children with familial hypercholesterolemia could benefit with greater cholesterol lowering and might be better off with a pill than an injection.” That would be good reason to emphasize the enrollment of children in the drug’s upcoming clinical trials, Dr. Goldberg said.

But cost could potentially become restrictive for MK-0616 as well, should it ever be approved. “If it’s priced too high, then are you really going to see the increased use?” she posed. “Certainly, there’s a high bar for therapies that are add-on to statins in terms of cost effectiveness.”

In the first of the two trials, 60 predominantly White male participants aged 50 or younger were randomly assigned to receive a single dose of MK-0616, at different levels ranging from 10 mg to 300 mg, or placebo. They subsequently crossed over to a different group for a second round of dosing. Both times, three participants took the drug for every one who received placebo.

Participants who took the active drug, regardless of dosage, showed greater than 90% reductions in circulating PCSK9 levels compared to baseline. Six participants discontinued the study before its completion.

In the second trial, 40 White adults aged 65 or younger (mean, 58), including 13 women, with LDL-C of 60 mg/dL to 160 mg/dL (mean, 87 mg/dL) on statin therapy for at least 3 months were randomly assigned 3-to-1 to add-on MK-0616, either 10 mg or 20 mg daily, or placebo for 14 days.

LDL-C levels fell an average of about 65% over the 2 weeks among those taking the active drug; they declined less than 5% for those who took placebo.

There were no deaths or serious adverse events in either trial, Dr. Johns reported. On the other hand, pharmacokinetics studies showed that exposure to the drug fell by “about 50%-60%” when dosing was preceded by food intake within the previous 30 minutes. “However, if a meal is consumed 30 minutes after the dose, this food effect is much, much less prominent, almost negligible.”

These preliminary results show the drug is “orally bioavailable and exerts a clinically meaningful effect,” Dr. Johns said. “However, there’s definitely more to be done. And we are planning the next phase of clinical development, a phase 2 trial, sometime next year.”

The research was funded by Merck. Dr. Johns disclosed employment with and equity ownership in Merck, as did all the study’s coauthors. Dr. Goldberg disclosed holding research contracts through her institution with Regeneron/Sanofi-Aventis, Amarin, Amgen, Pfizer, IONIS/Akcea, Regeneron, Novartis, Arrowroot Pharmaceuticals, and the FH Foundation; and consulting for Novartis, Akcea, Regeneron, and Esperion.

The investigational PCSK9 inhibitor that Merck showcased recently would be more than a “me-too” drug if it ultimately wins approval, despite competition from several approved agents that slash elevated cholesterol levels by targeting the same protein.

Two-fifths of adolescents and young adults in the United States may have nonalcoholic fatty liver disease (NAFLD), many with significant or advanced fibrosis, results of a nationwide surveillance study suggest.

In addition, among those who drink alcohol in excess, slightly more than half may have alcohol-associated fatty liver disease (ALD) that may lead to moderate to severe fibrosis in a substantial proportion, said Naim Alkhouri, MD, from Arizona Liver Health, Peoria, during a presentation of the findings at The Liver Meeting 2021: American Association for the Study of Liver Diseases (AASLD), held online.

“Efforts should focus on increasing awareness of the burden of ALD and NAFLD in this population and [mitigating] modifiable risk factors to prevent disease development and disease progression to potentially advanced fibrosis and cirrhosis,” he said.
 

Liver stiffness measured

Unlike previous studies that relied on liver enzyme levels or ultrasonography to estimate the prevalence of fatty liver disease among adolescents and young adults in the United States, Dr. Alkhouri and colleagues used valid liver ultrasonographic elastography (FibroScan) measurements, recorded during 2017-2018, from the National Health and Nutrition Examination Survey (NHANES) database.

The sample included participants aged 15 to 39 years. Those with viral hepatitis, alanine aminotransferase (ALT) levels greater than 500 U/L, or pregnancy were excluded.

The investigators divided the participants into those with excessive alcohol consumption, defined using the NHANES Alcohol Use Questionnaire as having more than two drinks per day for males or more than one drink per day for females, and those with no excessive alcohol consumption.

The authors used controlled attenuation parameters to identify participants with suspected ALD or NAFLD.

They then used liver stiffness measurement cutoffs of greater than or equal to 7.5 kPa to identify moderate fibrosis and greater than or equal to 9.5 kPa to identify severe fibrosis in those with evidence of ALD and cutoffs of greater than or equal to 6.1 kPa and greater than or equal to 7.1 kPa, respectively, in those with suspected NAFLD.

The cutoffs were chosen to maximize sensitivity, as determined from published literature, Dr. Alkhouri said.
 

Uncovering a high prevalence of ALD and NAFLD

The final sample comprised 1,319 participants, including 100 with excessive alcohol use and 1,219 without.

The heavy drinkers were significantly more likely to be older, male, White, current smokers, have lower platelet counts, higher aspartate aminotransferase (AST) and ALT levels, and higher mean corpuscular volumes.

Among the excessive drinkers, 52% had ALD. Of this group, 87.7% had either no or mild fibrosis, and 12.3% had moderate to severe fibrosis.

Among patients with excessive alcohol consumption, significant predictors of ALD included male sex, higher body mass index, ALT greater than the upper limit of normal, and higher A1c percentage.

Among those who were moderate drinkers or abstemious, 40% had NAFLD. Of this subgroup, 68.9% had no or mild fibrosis, and 31.1% had moderate to severe fibrosis.

Predictors of NAFLD in this group included older age, male sex, higher body mass index, and elevated ALT, AST, albumin, platelet counts, and A1c.
 

Is drinking underreported?

In a question-and-answer session following the presentation, co-moderator Miriam B. Vos, MD, a pediatric hepatologist at Children’s Healthcare of Atlanta, asked Dr. Alkhouri about his confidence in the accuracy of the measurements of alcohol consumption and whether there could be significant overlap between the ALD and NAFLD populations.

Dr. Alkhouri noted that he and his colleagues relied on items 121 and 130 of the NHANES Alcohol Use Questionnaire, which are self-reported by participants.

“Obviously, we’re not going to get honest answers all the time,” he said. “We’ve seen even in NASH [nonalcoholic steatohepatitis] clinical trials that when patients say they do not drink any alcohol, if you actually look for alcohol metabolites, up to 20% may have some evidence of alcohol consumption.

“I’m sure there’s a lot of overlap, but there’s no formal assessment,” he added.

Dr. Alkhouri noted that among the cohort with ALD, obesity and increased A1c were prevalent, “so it goes both ways. I think NAFLD can also contribute to progression of ALD, and that’s why we need to study another entity called ‘both alcoholic and nonalcoholic fatty liver disease.’”

Dr. Vos suggested that biomarkers may be useful for detecting alcohol use among patients with NAFLD and for further study of the progression of NAFLD to ALD.

No source of funding for the study has been disclosed. Dr. Alkhouri and Dr. Vos reported no relevant financial relationships.

The decision to initiate biologics early in the treatment of Crohn’s disease (CD) and ulcerative colitis (UC) should be based on complication risk, not on the assumption that earlier treatment produces better results, new research suggests.

Results of a meta-analysis of randomized controlled trials show that “the proportional biologic/placebo treatment effect on remission and response to biologics was not influenced by disease duration in UC or CD patients,” the investigators note.

“Patients with Crohn’s disease treated with biologics early on show over 40% remission rate, compared [with] around 30% for those with disease of 20 years or more,” study investigator Shomron Ben-Horin, MD, Sheba Medical Center, Tel Aviv University, Israel, told this news organization.

The rates of remission with both biologics and placebo were higher for patients with short-duration CD compared with patients with disease of longer duration. However, for patients with UC, the remission rates with both biologics and placebo were similar regardless of disease duration.

“Our findings support the use of biologics in patients with Crohn’s disease early after diagnosis, if they are at high risk of disease progression and complications, but not just to achieve better efficacy,” Dr. Ben-Horin said.

The meta-analysis was published online in Gastroenterology.
 

Getting the timing right

Dr. Ben-Horin led the research with an international group of investigators who assessed individual data from 6,168 patients with CD and 3,227 patients with UC. The patients were participants in 25 placebo-controlled trials.

For patients with CD, the odds ratio of achieving remission with biologics in comparison with placebo was 1.47 (95% confidence interval, 1.01-2.15) for short-duration disease (≤18 months), which was not so different from the odds ratio for longer-duration disease (>18 months) (OR, 1.43; 95% CI, 1.19-1.72).

“These results remained similar when tested for other disease duration cutoffs or when accounting for individual patients’ characteristics, such as whether patients were previously exposed to biologics or not,” said Dr. Ben-Horin.

For patients with UC, the OR for remission with biologics in comparison with placebo was 1.82 (95% CI, 1.12-2.97) for those with short-duration disease and 2.21 (95% CI, 1.79-2.72) for those with long-duration disease.

What the optimal timing is for using biologics for patients with inflammatory bowel disease (IBD), which includes both CD and UC, and whether all patients with these conditions need them are very pertinent questions, said Dr. Ben-Horin.

About a decade ago, the treatment of IBD changed. At that time, patients were initially treated with immunomodulators or steroids; biologics were used only if those treatments failed. More recently, a top-down approach has been followed, in which biologics are brought in at the beginning of the treatment protocol, said Dr. Ben-Horin.

This top-down approach has been widely adopted to prevent complications, such as intestinal strictures, bowel obstruction, or fistulas, which can increase the odds that patients with CD will require surgery, he added.

Although treatment with biologics was more effective when initiated earlier than later, data to support this were limited, prompting the investigators to conduct the current review.

“A substantial fraction of patients with Crohn’s disease may be better off with biologics first if they are at a high risk of complications: for example, smokers, patients with extensive disease, or those with perianal fistula. But this may not be necessarily true for those with a low risk of complications,” said Dr. Ben-Horin.

For patients with UC, “the lack of better efficacy with biologics in short-duration disease forces us to rethink our protocols of an early start of biologics,” he added.
 

Possible reasons for the early response

The reasons for the higher response to both placebo and biologics for patients with early CD are unknown.

“It may be that there is plasticity in Crohn’s disease early in the course of disease, where the tissue is more amenable to return to normal whether the patient is on placebo or treatment,” said Dr. Ben-Horin.

He suspects that the more likely explanation is that the placebo response is higher in patients with CD of short duration.

“When we looked at levels of C-reactive protein, this was reduced by biologics at similar magnitude in early- and late-disease patients,” Dr. Ben-Horin said. He noted that more studies are needed to better understand disease dynamics with these conditions.

Commenting on the findings, Stephen B. Hanauer, MD, from Northwestern University Feinberg School of Medicine, Chicago, noted that they “absolutely support earlier intervention for moderate-severe Crohn’s disease from diagnosis, rather than waiting for transmural progression that will make disease more refractory to any mechanism of action.”

“Unfortunately, the average duration of disease in biologic trials is often close to 10 years, which implies a more refractory population,” Dr. Hanauer said.

“Furthermore, in the United States, clinicians and patients are hampered by inability to gain third-party authorization for biologics or advanced oral agents, such as JAK inhibitors or S1P modulators, until failure of so-called conventional agents despite labeling indication for moderate-severe disease,” he added.

Dr. Ben-Horin has received consultancy and/or advisory board fees from AbbVie, Novartis, Schering-Plough, Janssen, Celltrion, GSK, Pfizer, Galmed, and Takeda and research support from AbbVie, Janssen, Celltrion, Galmed, and Takeda. Dr. Hanauer is a consultant and speaker for AbbVie, Janssen, and Takeda.

About a decade ago, the treatment of IBD changed. At that time, patients were initially treated with immunomodulators or steroids; biologics were used only if those treatments failed. More recently, a top-down approach has been followed, in which biologics are brought in at the beginning of the treatment protocol, said Dr. Ben-Horin.

This top-down approach has been widely adopted to prevent complications, such as intestinal strictures, bowel obstruction, or fistulas, which can increase the odds that patients with CD will require surgery, he added.

Although treatment with biologics was more effective when initiated earlier than later, data to support this were limited, prompting the investigators to conduct the current review.

“A substantial fraction of patients with Crohn’s disease may be better off with biologics first if they are at a high risk of complications: for example, smokers, patients with extensive disease, or those with perianal fistula. But this may not be necessarily true for those with a low risk of complications,” said Dr. Ben-Horin.

For patients with UC, “the lack of better efficacy with biologics in short-duration disease forces us to rethink our protocols of an early start of biologics,” he added.
 

Possible reasons for the early response

The reasons for the higher response to both placebo and biologics for patients with early CD are unknown.

“It may be that there is plasticity in Crohn’s disease early in the course of disease, where the tissue is more amenable to return to normal whether the patient is on placebo or treatment,” said Dr. Ben-Horin.

He suspects that the more likely explanation is that the placebo response is higher in patients with CD of short duration.

“When we looked at levels of C-reactive protein, this was reduced by biologics at similar magnitude in early- and late-disease patients,” Dr. Ben-Horin said. He noted that more studies are needed to better understand disease dynamics with these conditions.

Commenting on the findings, Stephen B. Hanauer, MD, from Northwestern University Feinberg School of Medicine, Chicago, noted that they “absolutely support earlier intervention for moderate-severe Crohn’s disease from diagnosis, rather than waiting for transmural progression that will make disease more refractory to any mechanism of action.”

“Unfortunately, the average duration of disease in biologic trials is often close to 10 years, which implies a more refractory population,” Dr. Hanauer said.

“Furthermore, in the United States, clinicians and patients are hampered by inability to gain third-party authorization for biologics or advanced oral agents, such as JAK inhibitors or S1P modulators, until failure of so-called conventional agents despite labeling indication for moderate-severe disease,” he added.

Dr. Ben-Horin has received consultancy and/or advisory board fees from AbbVie, Novartis, Schering-Plough, Janssen, Celltrion, GSK, Pfizer, Galmed, and Takeda and research support from AbbVie, Janssen, Celltrion, Galmed, and Takeda.

The decision to initiate biologics early in the treatment of Crohn’s disease (CD) and ulcerative colitis (UC) should be based on complication risk, not on the assumption that earlier treatment produces better results, new research suggests.

Results of a meta-analysis of randomized controlled trials show that “the proportional biologic/placebo treatment effect on remission and response to biologics was not influenced by disease duration in UC or CD patients,” the investigators note.

“Patients with Crohn’s disease treated with biologics early on show over 40% remission rate, compared [with] around 30% for those with disease of 20 years or more,” study investigator Shomron Ben-Horin, MD, Sheba Medical Center, Tel Aviv University, Israel, told this news organization.

The rates of remission with both biologics and placebo were higher for patients with short-duration CD compared with patients with disease of longer duration. However, for patients with UC, the remission rates with both biologics and placebo were similar regardless of disease duration.

“Our findings support the use of biologics in patients with Crohn’s disease early after diagnosis, if they are at high risk of disease progression and complications, but not just to achieve better efficacy,” Dr. Ben-Horin said.

The meta-analysis was published online in Gastroenterology.
 

Getting the timing right

Dr. Ben-Horin led the research with an international group of investigators who assessed individual data from 6,168 patients with CD and 3,227 patients with UC. The patients were participants in 25 placebo-controlled trials.

For patients with CD, the odds ratio of achieving remission with biologics in comparison with placebo was 1.47 (95% confidence interval, 1.01-2.15) for short-duration disease (≤18 months), which was not so different from the odds ratio for longer-duration disease (>18 months) (OR, 1.43; 95% CI, 1.19-1.72).

“These results remained similar when tested for other disease duration cutoffs or when accounting for individual patients’ characteristics, such as whether patients were previously exposed to biologics or not,” said Dr. Ben-Horin.

For patients with UC, the OR for remission with biologics in comparison with placebo was 1.82 (95% CI, 1.12-2.97) for those with short-duration disease and 2.21 (95% CI, 1.79-2.72) for those with long-duration disease.

More than half of chronic hepatitis B e antigen–negative patients who withdraw from nucleoside or nucleotide analogue therapy experienced relapse within 4 years, according to a new study that looked at patients from 11 centers in Europe, North America, and Asia.

“We wanted to see if the patients stabilize after that year. Are they just having relapses within the first year, and then they’re inactive carriers? Especially patients who don’t achieve [hepatitis B surface antigen; HBsAg] loss. Is that mildly active disease? Would they have been better off being retreated, or are they better off [staying off] therapy? It is important to look at what happens among these patients who stop and if there is a way to tell which way they’re going to go,” said Grishma Hirode, who is a PhD candidate at the University of Toronto. Ms. Hirode presented the multinational study at the annual meeting of the American Association for the Study of Liver Diseases.

The study provided a clear picture: “They do not stabilize after 1 year. They have relapses, and these relapses aren’t mild fluctuations,” said Ms. Hirode. Another study, which was presented during the same session and investigated a national cohort in Taiwan, also found a high rate of flareups and retreatment out to 4 years.

The RETRACT-B study presented by Ms. Hirode collected data on 945 patients from 11 centers in North America, Europe, and Asia. Overall, 66% had at least one relapse within 1 year of drug withdrawal. At 2 years, 40% had a sustained remission without HBsAg loss, as had 20% at 4 years; 44% had sustained remission or HBsAg loss at 2 years, as did 30% at 4 years.

Subgroup analyses found differences between some populations: 48% of Whites and 28% of Asians had sustained remission or HBsAg loss, and 30% of Whites and 20% of Asians had sustained remission without HBsAg loss. Patients who were HBsAg positive at start of therapy were more likely to have a sustained remission or HBsAg loss (36% vs. 28%; P < .05) and to have a sustained remission without HBsAg loss (31% vs. 19%; P < .05). HBsAg levels below 100 IU/mL at cessation was also associated with a greater chance of sustained remission or HBsAg loss (58% vs. 24%; P < .05) and sustained remission without HBsAg loss (24% vs. 20%; P < .05). Not having a relapse within the first year after cessation was also associated with greater chance of sustained remission or HBsAg loss (50% versus 19%; P < .05) and sustained remission without HBsAg loss (37% vs. 13%; P < .05).

The Taiwan cohort study examined the repercussions of a government policy that limited reimbursement of nucleotide/nucleoside analogues to a fixed duration of time. Among 10,192 eligible patients, researchers at I-SHOU University found a 6.58% 4-year cumulative incidence of severe flare-ups after discontinuation (95% confidence interval, 5.91%-7.30%), defined as serum ALT levels higher than five times the upper limit of normal plus serum bilirubin levels above 2 mg/dL.

The overall incidence of flare-ups was 30.66% over 4 years (95% CI, 29.37%-31.96%). Higher risk of flareup was associated with older age (hazard ratio for each 10 years, 1.19; P<.0001), male sex (HR, 1.76; P < .0001), a diagnosis of cirrhosis (HR, 1.84; P < .0001), and a history of hepatic decompensation (HR, 1.45; P = .044).

The 4-year incidence of retreatment was 48.74% (95% CI, 46.55-50.90%)

The mortality rate was 0.63% at 4 years after a flareup (95% CI, 0.44-0.87%), and the combined rate of mortality or liver transplant was 0.79% (95% CI, 0.58-1.05%). Risk factors for higher mortality included older age (per 10 years; HR, 1.70; P < .0001), a diagnosis of cirrhosis (HR, 6.12; P < .0001), and hypertension (HR, 2.29; P = .029).
 

Selecting patients safely?

The results of both studies suggest that withdrawal from medication should be done cautiously, and patients monitored for relapse and retreatment, according to Anna Lok, MD, who was asked for comment. Dr. Lok is a professor of internal medicine, director of clinical hematology, and assistant dean for clinical research at the University of Michigan, Ann Arbor.

Between the two studies, “the message is that this approach can benefit some patients, but if the goal of treatment withdrawal is to increase the rate of hepatitis B surface antigen loss, only a small percentage of patients would benefit. Contrary to studies in Europe, the rates of HBsAg loss in studies with predominantly Asian patients are much lower,” said Dr. Lok.

The new studies provide guidance as for which patients might safely stop treatment; specifically, she suggested, young White patients who have a low HBsAg level when treatment is stopped. “But you probably shouldn’t be trying it in older Asian patients who still have high HBsAg titer, because the chance of them relapsing is very high and the chance of benefit is very low,” she said.

“One has to be very careful in selecting which patients you’re going to try this on. And if you do want to try, you’ve got to make sure that you monitor patients very carefully so treatment can be promptly resumed if necessary because some of the patients can have a severe flare and they can even develop liver failure, and this should never be tried in patients with cirrhosis” said Dr. Lok.

LAS VEGAS – Clinical trials of treatments for inflammatory bowel disease (IBD) have disproportionately enrolled White people, researchers say.

These skewed demographics could result in researchers overlooking differences in how the disease and its treatments might affect other racial and ethnic groups, said Jellyana Peraza, MD, a chief resident at Albert Einstein College of Medicine, New York.

“The only way we can determine that therapies work differently in different populations is by including those populations in these clinical trials,” she said in an interview. “We think that diversity should be present, and that will answer some questions about the pathogenesis of the disease in general.”

Dr. Peraza presented the findings at the annual meeting of the American College of Gastroenterology.

Previous studies have found that, in trials of other conditions, such as cancer and cardiovascular disease, White people have been disproportionately represented. However, little research has been conducted regarding race and ethnicity in IBD trials.

To fill that gap, Dr. Peraza and colleagues analyzed data from completed trials through the U.S. National Library of Medicine’s registry, ClinicalTrials.gov, for the period from 2000 to 2020.

They found 22 trials conducted exclusively in the United States and 56 conducted in other countries that reported the race or ethnicity of participants; 54 trials did not include this information.

With regard to the prevalence of IBD in White people and Asian people, these populations were overrepresented in U.S. clinical trials. All other groups were underrepresented.
