There are millions of immature connections between the neurons in brains of adults that remain inactive until they’re recruited to help form new memories, according to neuroscientists from the Massachusetts Institute of Technology.

What to know:

• An estimated 30% of all synapses in the brain’s cortex are silent and become active to allow the adult brain to continually form new memories and leave existing conventional synapses unmodified.
• Silent synapses are looking for new connections, and when important new information is presented, connections between the relevant neurons are strengthened to allow the brain to remember new things.
• Using the silent synapses for the new memories does not overwrite the important memories stored in more mature synapses, which are harder to change.
• The brain’s neurons display a wide range of plasticity mechanisms that account for how brains can efficiently learn new things and retain them in long-term memory.
• Flexibility of synapses is critical for acquiring new information, and stability is required to retain important information, enabling one to more easily adjust and change behaviors and habits or incorporate new information.

When New York oncologist Gabriel Sara, MD, approached the French actress and film director Emmanuelle Bercot after a screening of one of her films in Manhattan, he was thinking big.

He never dreamed she would think bigger.  

“I thought maybe she will do a movie about some of my beliefs,” he said.

“Ma’am, would you like to go in the trenches of cancer?” he asked her, inviting her to tour the oncology department at Mount Sinai West.

Whether it was the Lebanese-born doctor’s Parisian French, his gentle, double-handed handshake, or the perpetual twinkle in his eye, something convinced Ms. Bercot to go. After the visit, she decided to base an entire film on the doctor’s philosophy about death, and she even cast him as one of the leads.

With no formal training in acting, “it’s incredible and prodigious what he did,” Ms. Bercot said in an interview at the 2021 Cannes Film Festival, where the film, “Peaceful” (“De Son Vivant”) premiered.

“This is a guy we took from his cancer ward to a film set, and he was able to be as real and authentic as he is in his doctor’s office,” she said.

Dr. Sara said that authenticity came easily, given that “a lot of my dialogue – maybe most – came from things I shared with Emmanuelle,” he said in an interview with this news organization. “She took the information from me, and she created the whole story. She studied my character and came up with really all the messages that I was hoping to share.”

He said that acting alongside professionals was not intimidating once he realized he was simply playing himself. “At some point ... it clicked in my head. Let me stop acting – I should just be me,” he recalled.

“Peaceful,” performed in French with English subtitles, was nominated for Best Film at the 2022 Lumières Awards.

It tells the story of a 39-year-old man (played by French actor Benoît Magimel) diagnosed with stage 4 pancreatic cancer and the journey, along with his mother (played by renowned actress Catherine Deneuve), through diagnosis, denial, and eventual acceptance of his death.

It is also the story of an oncologist, played by Dr. Sara as himself, who takes his patient by the hand, and refuses to sugarcoat the truth, because he believes that it is only by facing the facts that patients can continue to live – and then die – in peace.

“You’ll never hear me say I’ll cure your cancer. I’d be a liar if I did,” he tells his patient in the film.

“Patients put their life in your hands, so if you don’t tell them the truth you are betraying them,” he explained in the interview. “I have refused to see patients whose family did not allow them to come to the consultation to hear the truth. ... Nobody hears the truth and feels great about it the next day, but the truth helps them focus on what they need to deal with. And once they focus, they’re in control ... a big part of what is terrible for patients is that loss of control.”

The approach may sound harsh, but it is conveyed tenderly in the film. “[Your mother] thinks that half-truths will hurt you half as much,” he tells his patient gently, but “the scariest thing is realizing someone is lying to you. ... We have a tough journey ahead, there’s no room for lies. ... For me, truth is nonnegotiable.”  

Dr. Sara is brimming with stories of real-life patients whose lives were enriched and empowered by the clarity they gained in knowing the full truth.

However, not all oncologists agree with his style.

After screenings of the film in other parts of the world, and even in the United States, he has encountered some physicians who strongly disagree with his uncompromising honesty. “You always have somebody who says you know, in America, you will receive the truth but not in our culture – people are not used to it. I hear this all the time,” he said.

“And a long time ago, I decided I’m not going to accept that conversation. Truth works with all patients across all cultures,” Dr. Sara insisted.

“However, as caregivers, we have to be sensitive and present to the kind of culture we are dealing with. The content has to be always 100% honest but we adapt our language to the cultural and emotional state of the patient in order to successfully transmit the message,” he added.

Helping patients digest the news of their diagnosis and prognosis has been Dr. Sara’s recipe for his own survival at work. Now 68 and recently retired as medical director of the chemotherapy infusion suite and executive director of the patient services initiative at Mount Sinai West, he says he emerged from 40 years of practice without burning out by learning to step in time with each patient.

“My recipe for it is tango,” he said. Regular tango performances on his cancer ward were among his many real-life techniques that Ms. Bercot incorporated into the film. “I feel that we have to dance closely with our patients’ emotion,” he explained. “We have to feel our patients’ emotion and work with that. If you don’t move in harmony with your partner, you trip together and both of you will fall,” he told an audience after a screening of his film in New York City.

“I completely try to isolate my mind from anything else in order to be with the patient – this is what presence is about for me – to be right there for them, close to them. To spend that whole moment with them. That’s what will make the consultation really helpful, and will make me feel that I can move to the next page without feeling exhausted from the first one.”

A key scene in the film comes after the patient’s mother is stunned to discover a cheerful tango performance on her son’s ward, and confronts the doctor angrily.

“It’s like I’m abandoning him,” she says tearfully, when the doctor urges her to accept that her son’s chemotherapy is no longer working and let him live what life he has left.

“Give him permission to go,” he urges her. “It would be your greatest gift of love.”

Dr. Sara encourages a similar approach in his staff. He warns them about the “hero syndrome,” in which dying patients are made to feel they need to “hang on” and “fight” for the sake of their caregivers and families.

“The patient never asked to be the hero, but our attitude is telling him that he’s the hero,” he says in the film. “That puts him in an intolerable impasse because he figures that if he gives up, if he dies, he’s betraying his fans. He needs the exact opposite: to be set free. He needs the permission to die. That permission is given by two people: his doctor and his family.”

Of course, not all cancer patients have such a dim prognosis, and Dr. Sara is the first to forge ahead if he feels it’s appropriate. “If, if there is no option for them, I’m going to be aggressive to protect them. But when there is a curable disease, I will go broke to try to treat my patient. I’m willing to give them toxic drugs and hold their hand, get them through the storm if I believe it’s going to cure what they have, and I will coach them to accept being sick.”

He also believes in physical contact with the patient. “If we have some intimacy with the patient, we can at least palpate the kind of person they are,” he said. But his wife Nada pointed out that physical examinations can sometimes make patients nervous. “She told me, if you have a tie, they might have fun looking at it.” Thus began Dr. Sara’s collection of about 30 fun ties decorated with unicorns or jellyfish tailored to various patients’ preferences.

In the film, his patient teases him about this quirk, but Dr. Sara insists it is a small gesture that carries meaning. “One patient told me a story about lovebugs. She would see them in her kitchen when she was feeling well – so lovebugs became a sign of hope for her. I was telling the story to my wife ... so she got me a tie with lovebugs on it, and my patient was so happy when she saw me wearing that.”

In the film – and in real life – Dr. Sara often played guitar at breakfast music sessions with his staff in which he encouraged them to express their feelings about patients’ struggles. “If you cry, don’t be ashamed. Your patient will feel you’re with him,” he said in the film. In the final scenes, wearing a cloud-covered tie, he says goodbye to his patient with tears in his eyes. “They [the tears] are sincere,” he recalled. “Because I really felt I was looking at a dying patient. I really did.”

COVID-19 remains deadlier than influenza in severe cases requiring hospitalization, a new study shows.

People who were hospitalized with Omicron COVID-19 infections were 54% more likely to die, compared with people who were hospitalized with the flu, Swiss researchers found.

The results of the study continue to debunk an earlier belief from the start of the pandemic that the flu was the more dangerous of the two respiratory viruses. The researchers noted that the deadliness of COVID-19, compared with flu, persisted “despite virus evolution and improved management strategies.”

The study was published in JAMA Network Open and included 5,212 patients in Switzerland hospitalized with COVID-19 or the flu. All the COVID patients were infected with the Omicron variant and hospitalized between Jan. 15, 2022, and March 15, 2022. Flu data included cases from January 2018 to March 15, 2022. 

Overall, 7% of COVID-19 patients died, compared with 4.4% of flu patients. Researchers noted that the death rate for hospitalized COVID patients had declined since their previous study, which was conducted during the first COVID wave in the first half of 2020. At that time, the death rate of hospitalized COVID patients was 12.8%. 

Since then, 98% of the Swiss population has been vaccinated. “Vaccination still plays a significant role regarding the main outcome,” the authors concluded, since a secondary analysis in this most recent study showed that unvaccinated COVID patients were twice as likely to die, compared with flu patients.

“Our results demonstrate that COVID-19 still cannot simply be compared with influenza,” they wrote.

While the death rate among COVID patients was significantly higher, there was no difference in the rate that COVID or flu patients were admitted to the ICU, which was around 8%.

A limitation of the study was that all the COVID cases did not have laboratory testing to confirm the Omicron variant. However, the study authors noted that Omicron accounted for at least 95% of cases during the time the patients were hospitalized. The authors were confident that their results were not biased by the potential for other variants being included in the data.

Four coauthors reported receiving grants and personal fees from various sources.

Overall, 7% of COVID-19 patients died, compared with 4.4% of flu patients. Researchers noted that the death rate for hospitalized COVID patients had declined since their previous study, which was conducted during the first COVID wave in the first half of 2020. At that time, the death rate of hospitalized COVID patients was 12.8%. 

Since then, 98% of the Swiss population has been vaccinated. “Vaccination still plays a significant role regarding the main outcome,” the authors concluded, since a secondary analysis in this most recent study showed that unvaccinated COVID patients were twice as likely to die, compared with flu patients.

“Our results demonstrate that COVID-19 still cannot simply be compared with influenza,” they wrote.

While the death rate among COVID patients was significantly higher, there was no difference in the rate that COVID or flu patients were admitted to the ICU, which was around 8%.

A limitation of the study was that all the COVID cases did not have laboratory testing to confirm the Omicron variant. However, the study authors noted that Omicron accounted for at least 95% of cases during the time the patients were hospitalized. The authors were confident that their results were not biased by the potential for other variants being included in the data.

The American College of Cardiology, the American Heart Association, and the Society for Cardiovascular Angiography and Interventions (SCAI) have jointly issued new guidance outlining competency-based advanced training requirements for interventional cardiology trainees.

It’s the first document of its kind to define the training requirements for the full breadth of interventional cardiology for adults, including coronary interventions, peripheral vascular interventions (PVIs), and structural heart interventions (SHIs), the organizations say.

Minimum of 250 procedures

To gain the necessary experience in interventional cardiology, cardiovascular fellows are advised to complete the following:

• A 3-year general cardiovascular disease fellowship (successful completion consists of Level I competency in all aspects of cardiovascular medicine and Level II competency in diagnostic cardiac catheterization to pursue interventional cardiology training);
• A 1-year accredited interventional cardiology fellowship, the focus of which is coronary intervention with the opportunity to gain procedural experience in various aspects of PVI or SHI (Level III competency);
• An option for additional post-fellowship training based on the trainee’s career goals.

The goal of Level III training is to provide the interventional cardiology trainees with a “well-rounded, competency-based education,” including didactic instruction, clinical experience in the diagnosis and care of patients, and hands-on procedural experience, the writing group says.

Competency requirements are defined using the Accreditation Council for Graduate Medical Education’s six “essential” competency domains: medical knowledge; patient care and procedural skills; practice-based learning and improvement; systems-based practice; interpersonal and communication skills; and professionalism.

To support attaining these competencies, the writing committee recommends a minimum of 250 interventional cardiology procedures. Of these, 200 should be coronary procedures, with the remaining 50 specialized in coronary, PVI, or SHI, which allows the fellows to customize training on the basis of their career goals.

Adjunctive procedures related to physiologic assessment and intracoronary imaging are also required (25 of each). “These minimum numbers are meant to provide trainees with exposure to a variety and spectrum of complexity of clinical case material and give supervising faculty sufficient opportunity to evaluate trainees’ competency,” the writing group says.

In addition to their procedural skills, evaluation of interventional cardiology trainee proficiency should include regular assessment of a trainee’s ability to clinically diagnose and manage patients across the broad spectrum of diseases.

Assessment of trainees should involve multiple components, including direct observation by instructors, case logs, chart reviews (including adherence to guideline recommendations, appropriate use criteria, and patient outcomes), simulation training, and assessment of leadership skills.

Trainees must also acquire experience working as part of a multidisciplinary team to provide a holistic approach to patient care. The document also highlights the importance of leadership skills, mentorship and lifelong learning beyond initial training.

The 2023 ACC/AHA/SCAI Advanced Training Statement on Interventional Cardiology (Coronary, Peripheral Vascular, and Structural Heart Interventions) was published online in the Journal of the American College of Cardiology.

The statement was developed in collaboration with and endorsed by the American Association for Thoracic Surgery, the American Society of Echocardiography, the Heart Failure Society of America, the Heart Rhythm Society, the Society of Cardiovascular Anesthesiologists, the Society of Cardiovascular Computed Tomography, the Society for Cardiovascular Magnetic Resonance, the Society of Thoracic Surgeons, and the Society for Vascular Medicine.

Treatment with the diabetes drug metformin shows a significant, dose-dependent effect in lowering SARS-CoV-2 viral load within days of administration, according to the latest analysis of the phase 3 COVID-OUT trial. These findings add to a multitude of benefits the drug has been shown to have in COVID infection.

COVID-OUT did not meet its primary endpoint, but it did show important secondary outcomes including a 42% reduction in ED visits and in hospitalizations and/or deaths by day 14, and a 58% reduction in hospitalizations/death by day 28. A further subanalysis has shown a 42% reduction in long COVID, compared with placebo.

“In this phase 3 randomized controlled trial, metformin showed prevention of severe COVID, prevention of long COVID, and an antiviral effect, and this is consistent with other data,” said coauthor Carolyn Bramante, MD, University of Minnesota, Minneapolis, in presenting the findings at the Conference on Retroviruses & Opportunistic Infections.
 

Study details

For the new subanalysis, the authors further evaluated the effects of metformin treatment on SARS-CoV-2 viral load.

A total of 1,323 patients in the study, enrolled at six centers, were randomized to treatment either with metformin 1,000 mg per day on days 2-5 and 1,500 mg per day on days 6 to 14 (n = 187), or to ivermectin 390-470 mcg/kg per day for 3 days (n = 187), fluvoxamine 50 mg twice daily for 14 days, and/or an exact-matching placebo in a 2 x 3 factorial trial design.

The subanalysis on viral load included 483 patients from the trial who were treated with metformin versus 462 who received placebo, who were all enrolled within 3 days of a documented SARS-CoV-2 infection and less than 7 days after symptom onset.

The patients had a median age of 46 years, and all had either overweight or obesity. Only about 2% had diabetes, and only patients considered low-risk were excluded from the trial, including those under age 30 and those with a body mass index under 25.

About half of patients had received a primary vaccine and about 5% had received a vaccine booster. SARS-CoV-2 variants that were prominent during the study included Alpha, Delta, and Omicron.

The viral samples available on days 1, 5, and 10 showed a mean change in viral load from baseline to follow-up; the viral load was significantly lower with metformin versus placebo (–0.64 log10 copies/mL), representing a 4.4-fold greater decrease in viral load with metformin.

The mean rate of undetectable SARS-CoV-2 viral load at day 5 was 49.9% in the metformin group versus 54.6% in the placebo group (odds ratio, 1.235), and the undetectable rate at day 10 was 14.3% in the metformin group and 22.6% in the placebo group (OR, 1.663; P = .003).

An increased antiviral effect corresponded with increases in metformin dosing on days 6 through 14. Furthermore, the antiviral effect became stronger when metformin was started earlier in the course of infection.

Of note, the antiviral effect was more pronounced among those who were not vaccinated (mean, –0.95 log copies/mL), compared with the vaccinated (mean, –0.39 log copies/mL).

The antiviral effect with metformin was similar to that seen with nirmatrelvir at day 5 and was greater than nirmatrelvir at day 10.

No similar relationships in SARS-CoV-2 viral load were observed between ivermectin or fluvoxamine and placebo.

The findings are consistent with results of other recent observational studies, including research showing metformin to be associated with reductions in COVID-19 severity in patients with prediabetes, Dr. Bramante noted.

The authors’ previous analysis looking at long COVID in the COVID-OUT study showed that metformin treatment during acute COVID significantly reduced the risk for a diagnosis of long COVID versus placebo at 300 days following randomization, with a hazard ratio of 0.59 after adjustment for the study drug and vaccination at baseline.

Dr. Bramante noted that metformin’s potential antiviral properties have long been speculated, with some of the earliest research on the drug suggesting less severe outcomes in influenza, and more recently, RNA assays suggesting effects against other RNA viruses, including the Zika virus.

In terms of COVID, Dr. Bramante noted that the drug has plenty of potentially favorable benefits.

“Metformin is very safe and is known to have very few contraindications, so the next steps could be to consider looking at this in terms of a combination therapy,” she said.
 

‘Data from other studies are conflicting’

Commenting on the study, Diane V. Havlir, MD, cautioned that “metformin is currently not recommended in treatment guidelines, [and] data from other studies are conflicting; side effects can be an issue, and the study presented here was in a select population,” she said in an interview.

However, “what is both new and interesting in this presentation is the reduction of viral load, which [was observed] in the samples collected not only on days 1-5, but also days 6-14,” said Dr. Havlir, who is professor and associate chair of clinical research, department of medicine, and chief of the division of HIV, infectious diseases and global medicine and director of the AIDS Research Institute at the University of California, San Francisco.

Key questions the findings raise include whether the results correlate with clinical outcomes or transmission, and whether the findings are generalizable to other populations and settings, Dr. Havlir said.

Ultimately, “we need to continue to pursue all aspects of outpatient treatments for COVID to address questions like these for new and existing agents,” she added.

The trial received funding from the Parsemus Foundation, the Rainwater Charitable Foundation, Fast Grants, and the United Health Group. The authors and Dr. Havlir disclosed no relevant financial relationships.

Children born to mothers who had urinary or genital tract infections during pregnancy appear to have an increased risk for childhood leukemia, said researchers reporting a Danish registry analysis that may point to preventive strategies for the disease.

The research was published online in JAMA Network Open.

The team studied more than 2.2 million children born in Denmark over more than 3 decades, linking their records across multiple national registries to examine both later cancer risk and maternal infection rates.

They found that, overall, at least one maternal infection during pregnancy was associated with a 35% increased risk for leukemia in the children, rising to 65% for urinary tract infections, and 142% for genital infections.

“The findings of this large population-based cohort study suggest that maternal urinary and genital tract infections during pregnancy are associated with a higher risk of childhood leukemia in offspring,” said lead author Jian-Rong He, DPhil, division of birth cohort study, Guangzhou (China) Women and Children’s Medical Center.

However, he added, “the associated absolute risk remained small given the rarity” of the disease. In absolute terms, the risk difference between exposed and unexposed children was 1.8 cases per 100,000 person-years for any infection, 3.4 cases per 100,000 person-years for urinary traction infection, and 7.1 cases per 100,000 person-years for genital tract infection.

Maternal infections during pregnancy may be associated with chromosomal and immunologic alterations in the fetus, the authors speculated.

“Given that little is known about the etiology of childhood leukemia,” these results “suggest an important direction for research on the etiology of childhood leukemia as well as development of potential preventive measures,” they wrote.

In many countries, pregnant women are tested for urinary tract infection and bacterial vaginosis, and treated with antibiotics in antenatal care, as these infections are linked to adverse perinatal outcomes, they pointed out.
 

Study details

The team conducted a large population-based study that included all live births in Denmark between 1978 and 2015.

After exclusions, they gathered information on 2,222,797 children, linking data from several national registries, including the Danish Medical Birth Register, the Danish National Patient Registry, and the Danish National Cancer Registry, to identify cases of childhood cancers and maternal infection during pregnancy.

The results were then validated by comparing them with those in 2.6 million live births in Sweden between 1988 and 2014, for whom similar data were available through linkage with several Swedish registries.

The Danish cohort was followed up for a mean of 12 years per person, yielding a total of 27 million person-years. Just over half (51.3%) were boys.

Cancer was diagnosed in 4,362 children before 15 years of age, of whom 1,307 had leukemia (1,050 had acute lymphocytic leukemia), 1,267 had a brain tumor, 224 had lymphoma, and 1,564 had other cancers.

At least one infection during pregnancy was diagnosed in 81,717 mothers (3.7%). Urinary tract infections were the most common (in 1.7% of women), followed by genital tract infection (in 0.7%), digestive system infection (in 0.5%), and respiratory tract infection (in 0.3%).

Women with any infection during pregnancy were more likely to be younger and primiparous than were women who did not have infections, and they were also more likely to have fewer years of education, higher prepregnancy BMI, diabetes, and to smoke during early pregnancy.

Preterm delivery and low-birth-weight infants were also more common in women with infections during pregnancy.

Cox proportional hazards regression models revealed that, after adjustment for confounders, any maternal infection was associated with a hazard ratio of childhood leukemia of 1.35.

Further analysis revealed that the association was driven by genital tract infection, at a hazard ratio for childhood leukemia of 2.42, and urinary tract infection, at a hazard ratio 1.65.

Moreover, children born to women who had a sexually transmitted infection during pregnancy had a hazard ratio for developing leukemia of 3.13 compared with unexposed children.

There were no associations between other maternal infections and childhood leukemia.

The patterns of association between maternal infections and childhood leukemia were similar when looking at disease subtypes, as well as in the Swedish validation cohort, they added.

When interpreting the results, the researchers caution that, as data on maternal infection were drawn from hospital data, “milder infections and those not diagnosed or treated in specialized health care facilities were not captured.”

“Also, some infections could be captured because the mother sought care for other, more serious conditions, which might bias the association of maternal infections and childhood leukemia.”

The study was supported by grants from the China Scholarship Council–University of Oxford; National Natural Science Foundation of China; Danish Council for Independent Research; Nordic Cancer Union; Novo Nordisk Fonden; and the Swedish Council for Working Life and Social Research. Dr He reported receiving a PhD scholarship from the China Scholarship Council during the conduct of the study. Several other coauthors have disclosures; the full list can be found with the original article.

The team studied more than 2.2 million children born in Denmark over more than 3 decades, linking their records across multiple national registries to examine both later cancer risk and maternal infection rates.

They found that, overall, at least one maternal infection during pregnancy was associated with a 35% increased risk for leukemia in the children, rising to 65% for urinary tract infections, and 142% for genital infections.

“The findings of this large population-based cohort study suggest that maternal urinary and genital tract infections during pregnancy are associated with a higher risk of childhood leukemia in offspring,” said lead author Jian-Rong He, DPhil, division of birth cohort study, Guangzhou (China) Women and Children’s Medical Center.

However, he added, “the associated absolute risk remained small given the rarity” of the disease. In absolute terms, the risk difference between exposed and unexposed children was 1.8 cases per 100,000 person-years for any infection, 3.4 cases per 100,000 person-years for urinary traction infection, and 7.1 cases per 100,000 person-years for genital tract infection.

Maternal infections during pregnancy may be associated with chromosomal and immunologic alterations in the fetus, the authors speculated.

“Given that little is known about the etiology of childhood leukemia,” these results “suggest an important direction for research on the etiology of childhood leukemia as well as development of potential preventive measures,” they wrote.

In many countries, pregnant women are tested for urinary tract infection and bacterial vaginosis, and treated with antibiotics in antenatal care, as these infections are linked to adverse perinatal outcomes, they pointed out.
 

Study details

The team conducted a large population-based study that included all live births in Denmark between 1978 and 2015.

After exclusions, they gathered information on 2,222,797 children, linking data from several national registries, including the Danish Medical Birth Register, the Danish National Patient Registry, and the Danish National Cancer Registry, to identify cases of childhood cancers and maternal infection during pregnancy.

The results were then validated by comparing them with those in 2.6 million live births in Sweden between 1988 and 2014, for whom similar data were available through linkage with several Swedish registries.

The Danish cohort was followed up for a mean of 12 years per person, yielding a total of 27 million person-years. Just over half (51.3%) were boys.

Cancer was diagnosed in 4,362 children before 15 years of age, of whom 1,307 had leukemia (1,050 had acute lymphocytic leukemia), 1,267 had a brain tumor, 224 had lymphoma, and 1,564 had other cancers.

At least one infection during pregnancy was diagnosed in 81,717 mothers (3.7%). Urinary tract infections were the most common (in 1.7% of women), followed by genital tract infection (in 0.7%), digestive system infection (in 0.5%), and respiratory tract infection (in 0.3%).

Women with any infection during pregnancy were more likely to be younger and primiparous than were women who did not have infections, and they were also more likely to have fewer years of education, higher prepregnancy BMI, diabetes, and to smoke during early pregnancy.

Preterm delivery and low-birth-weight infants were also more common in women with infections during pregnancy.

Cox proportional hazards regression models revealed that, after adjustment for confounders, any maternal infection was associated with a hazard ratio of childhood leukemia of 1.35.

Further analysis revealed that the association was driven by genital tract infection, at a hazard ratio for childhood leukemia of 2.42, and urinary tract infection, at a hazard ratio 1.65.

Moreover, children born to women who had a sexually transmitted infection during pregnancy had a hazard ratio for developing leukemia of 3.13 compared with unexposed children.

There were no associations between other maternal infections and childhood leukemia.

The patterns of association between maternal infections and childhood leukemia were similar when looking at disease subtypes, as well as in the Swedish validation cohort, they added.

When interpreting the results, the researchers caution that, as data on maternal infection were drawn from hospital data, “milder infections and those not diagnosed or treated in specialized health care facilities were not captured.”

“Also, some infections could be captured because the mother sought care for other, more serious conditions, which might bias the association of maternal infections and childhood leukemia.”

The study was supported by grants from the China Scholarship Council–University of Oxford; National Natural Science Foundation of China; Danish Council for Independent Research; Nordic Cancer Union; Novo Nordisk Fonden; and the Swedish Council for Working Life and Social Research. Dr He reported receiving a PhD scholarship from the China Scholarship Council during the conduct of the study. Several other coauthors have disclosures; the full list can be found with the original article.

Gastroenterologists in 2023 will have more tools in their arsenal to treat patients with Crohn’s disease or ulcerative colitis. As many as 8-10 adalimumab biosimilars are anticipated to come on the market this year, giving mainstay drug Humira some vigorous competition.

Three scenarios will drive adalimumab biosimilar initiation: Insurance preference for the initial treatment of a newly diagnosed condition, a change in a patient’s insurance plan, or an insurance-mandated switch, said Edward C. Oldfield IV, MD, assistant professor at Eastern Virginia Medical School’s division of gastroenterology in Norfolk.

Even with more drugs to choose from, some gastroenterologists may be hesitant to make a switch. “Outside of these scenarios, I would encourage patients to remain on their current biologic so long as cost and accessibility remain stable,” said Dr. Oldfield.

Many factors will contribute to the success of biosimilars. Will physicians be prescribing them? How are biosimilars placed on formularies and will they be given preferred status?  How will manufacturers price their biosimilars? “We have to wait and see to get the answers to these questions,” said Steven Newmark, JD, MPA, chief legal officer and director of policy, Global Healthy Living Foundation/CreakyJoints, a nonprofit advocacy organization based in New York.

Prescribing biosimilars is no different than prescribing originator biologics, so providers should know how to use them, said Mr. Newmark. “Most important will be the availability of patient-friendly resources that providers can share with their patients to provide education about and confidence in using biosimilars,” he added.

Overall, biosimilars are a good thing, said Dr. Oldfield. “In the long run they should bring down costs and increase access to medications for our patients.”

Others are skeptical that the adalimumab biosimilars will save patients much money.

Biosimilar laws were created to lower costs. However, if a patient with insurance pays only $5 a month out of pocket for Humira – a drug that normally costs $7,000 without coverage – it’s unlikely they would want to switch unless there’s comparable savings from the biosimilar, said Stephen B. Hanauer, MD, medical director of the Digestive Health Center and professor of medicine at Northwestern Medicine, Northwestern University, Evanston, Ill.

Like generics, Humira biosimilars may face some initial backlash, said Dr. Hanauer.
 

2023 broadens scope of adalimumab treatments

The American Gastroenterological Association describes a biosimilar as something that’s “highly similar to, but not an exact copy of, a biologic reference product already approved” by the Food and Drug Administration. Congress under the 2010 Affordable Care Act created a special, abbreviated pathway to approval for biosimilars.

AbbVie’s Humira, the global revenue for which exceeded $20 billion in 2021, has long dominated the U.S. market on injectable treatments for autoimmune diseases. The popular drug faces some competition in 2023, however, following a series of legal settlements that allowed AbbVie competitors to release their own adalimumab biosimilars.

“So far, we haven’t seen biosimilars live up to their potential in the U.S. in the inflammatory space,” said Mr. Newmark. This may change, however. Previously, biosimilars have required infusion, which demanded more time, commitment, and travel from patients. “The new set of forthcoming Humira biosimilars are injectables, an administration method preferred by patients,” he said.

The FDA will approve a biosimilar if it determines that the biological product is highly similar to the reference product, and that there are no clinically meaningful differences between the biological and reference product in terms of the safety, purity, and potency of the product. 

The agency to date has approved 8 adalimumab biosimilars. These include: Idacio (adalimumab-aacf, Fresenius Kabi); Amjevita (adalimumab-atto, Amgen); Hadlima (adalimumab-bwwd, Organon); Cyltezo (adalimumab-adbm, Boehringer Ingelheim); Yusimry (adalimumab-aqvh from Coherus BioSciences); Hulio (adalimumab-fkjp; Mylan/Fujifilm Kyowa Kirin Biologics); Hyrimoz (adalimumab-adaz, Sandoz), and Abrilada (adalimumab-afzb, Pfizer).

“While FDA doesn’t formally track when products come to market, we know based on published reports that application holders for many of the currently FDA-approved biosimilars plan to market this year, starting with Amjevita being the first adalimumab biosimilar launched” in January, said Sarah Yim, MD, director of the Office of Therapeutic Biologics and Biosimilars at the agency.

At press time, two other companies (Celltrion and Alvotech/Teva) were awaiting FDA approval for their adalimumab biosimilar drugs.

Among the eight approved drugs, Cyltezo is the only one that has a designation for interchangeability with Humira.

An interchangeable biosimilar may be substituted at the pharmacy without the intervention of the prescriber – much like generics are substituted, depending on state laws, said Dr. Yim. “However, in terms of safety and effectiveness, FDA’s standards for approval mean that biosimilar or interchangeable biosimilar products can be used in place of the reference product they were compared to.”

FDA-approved biosimilars undergo a rigorous evaluation for safety, effectiveness, and quality for their approved conditions of use, she continued. “Therefore, patients and health care providers can rely on a biosimilar to be as safe and effective for its approved uses as the original biological product.”
 

Remicade as a yard stick

Gastroenterologists dealt with this situation once before, when Remicade (infliximab) biosimilars came on the market in 2016, noted Miguel Regueiro, MD, chair of the Digestive Disease and Surgery Institute at the Cleveland Clinic.

Remicade and Humira are both tumor necrosis factor inhibitors with the same mechanism of action and many of the same indications. “We already had that experience with Remicade and biosimilar switch 2 or 3 years ago. Now we’re talking about Humira,” said Dr. Regueiro.

Most GI doctors have prescribed one of the more common infliximab biosimilars (Inflectra or Renflexis), noted Dr. Oldfield.

Cardinal Health, which recently surveyed 300 gastroenterologists, rheumatologists, and dermatologists about adalimumab biosimilars, found that gastroenterologists had the highest comfort level in prescribing them. Their top concern, however, was changing a patient from adalimumab to an adalimumab biosimilar.

For most patients, Dr. Oldfield sees the Humira reference biologic and biosimilar as equivalent.

However, he said he would change a patient’s drug only if there were a good reason or if his hand was forced by insurance. He would not make the change for a patient who recently began induction with the reference biologic or a patient with highly active clinical disease.

“While there is limited data to support this, I would also have some qualms about changing a patient from reference biologic to a biosimilar if they previously had immune-mediated pharmacokinetic failure due to antibody development with a biologic and were currently doing well on their new biologic,” he said.

Those with a new ulcerative colitis or Crohn’s diagnosis who are initiating a biologic for the first time might consider a biosimilar. If a patient is transitioning from a reference biologic to a biosimilar, “I would want to make that change during a time of stable remission and with the recognition that the switch is not a temporary switch, but a long-term switch,” he continued.

A paper that reviewed 23 observational studies of adalimumab and other biosimilars found that switching biosimilars was safe and effective. But if possible, patients should minimize the number of switches until more robust long-term data are available, added Dr. Oldfield.

If a patient is apprehensive about switching to a new therapy, “one may need to be cognizant of the ‘nocebo’ effect in which there is an unexplained or unfavorable therapeutic effect after switching,” he said.

Other gastroenterologists voiced similar reservations about switching. “I won’t use an adalimumab biosimilar unless the patient requests it, the insurance requires it, or there is a cost advantage for the patient such that they prefer it,” said Doug Wolf, MD, an Atlanta gastroenterologist.

“There is no medical treatment advantage to a biosimilar, especially if switching from Humira,” added Dr. Wolf.

Insurance will guide treatment

Once a drug is approved for use by the FDA, that drug will be available in all 50 states. “Different private insurance formularies, as well as state Medicaid formularies, might affect the actual ability of patients to receive such drugs,” said Mr. Newmark.

Patients should consult with their providers and insurance companies to see what therapies are available, he advised.

Dr. Hanauer anticipates some headaches arising for patients and doctors alike when negotiating for a specific drug.

Cyltezo may be the only biosimilar interchangeable with Humira, but the third-party pharmacy benefit manager (PBM) could negotiate for one of the noninterchangeable ones. “On a yearly basis they could switch their preference,” said Dr. Hanauer.

In the Cardinal Health survey, more than 60% of respondents said they would feel comfortable prescribing an adalimumab biosimilar only with an interchangeability designation.

A PBM may offer a patient Cyltezo if it’s cheaper than Humira. If the patient insists on staying on Humira, then they’ll have to pay more for that drug on their payer’s formulary, said Dr. Hanauer. In a worst-case scenario, a physician may have to appeal on a patient’s behalf to get Humira if the insurer offers only the biosimilar.

Taking that step to appeal is a major hassle for the physician, and leads to extra back door costs as well, said Dr. Hanauer.

Humira manufacturer AbbVie, in turn, may offer discounts and rebates to the PBMs to put Humira on their formulary. “That’s the AbbVie negotiating power. It’s not that the cost is going to be that much different. It’s going to be that there are rebates and discounts that are going to make the cost different,” he added.

As a community physician, Dr. Oldfield has specific concerns about accessibility.

The ever-increasing burden of insurance documentation and prior authorization means it can take weeks or months to get these medications approved. “The addition of new biosimilars is a welcome entrance if it can get patients the medications they need when they need it,” he said.

When it comes to prescribing biologics, many physicians rely on ancillary staff for assistance. It’s a team effort to sift through all the paperwork, observed Dr. Oldfield.

“While many community GI practices have specialized staff to deal with prior authorizations, they are still a far cry from the IBD [inflammatory bowel disease] academic centers where there are often pharmacists, nursing specialists, and home-monitoring programs to check in on patients,” he explained.

Landscape on cost is uncertain

At present, little is known about the cost of the biosimilars and impact on future drug pricing, said Dr. Oldfield.

At least for Medicare, Humira biosimilars will be considered Medicare Part D drugs if used for a medically accepted indication, said a spokesperson for the Centers for Medicare and Medicaid Services.

Part D sponsors (pharmacy and therapeutic committees) “will make the determination as to whether Amjevita and other products will be added to their formularies,” said the spokesperson.

Patients never saw a significant cost savings with Remicade biosimilars. “I imagine the same would be true with biosimilars for Humira,” said Dr. Regueiro. Patients may see greater access to these drugs, however, because the insurance plan or the pharmacy plan will make them more readily available, he added.

The hope is that, as biosimilars are introduced, the price of the originator biologic will go down, said Mr. Newmark. “Therefore, we can expect Humira to be offered at a lower price as it faces competition. Where it will sit in comparison to the forthcoming biosimilars will depend on how much biosimilar companies drop their price and how much pressure will be on PBMs and insurers to cover the lowest list price drug,” he said.

AbbVie did not respond to several requests for comment.

Charitable patient assistance programs for biosimilars or biologics can help offset the price of copayments, Mr. Newmark offered.

Ideally, insurers will offer designated biosimilars at a reduced or even no out-of-pocket expense on their formularies. This should lead to a decreased administrative burden for approval with streamlined (or even removal) of prior authorizations for certain medications, said Dr. Oldfield.

Without insurance or medication assistance programs, the cost of biosimilars is prohibitively expensive, he added.

“Biosimilars have higher research, development, and manufacturing costs than what people conventionally think of [for] a generic medication.”

Educating, advising patients

Dr. Oldfield advised that gastroenterologists refer to biologics by the generic name rather than branded name when initiating therapy unless there is a very specific reason not to. “This approach should make the process more streamlined and less subjected to quick denials for brand-only requests as biosimilars start to assume a larger market share,” he said.

Uptake of the Humira biosimilars also will depend on proper education of physicians and patients and their comfort level with the biosimilars, said Dr. Regueiro. Cleveland Clinic uses a team approach to educate on this topic, relying on pharmacists, clinicians, and nurses to explain that there’s no real difference between the reference drug and its biosimilars, based on efficacy and safety data.

Physicians can also direct patients to patient-friendly resources, said Mr. Newmark. “By starting the conversation early, it ensures that when/if the time comes that your patient is switched to or chooses a biosimilar they will feel more confident because they have the knowledge to make decisions about their care.”

The Global Healthy Living Foundation’s podcast, Breaking Down Biosimilars , is a free resource for patients, he added.

It’s important that doctors also understand these products so they can explain to their patients what to expect, said the FDA’s Dr. Yim. The FDA provides educational materials on its website, including a comprehensive curriculum toolkit.

Dr. Hanauer has served as a consultant for AbbVie, Amgen, American College of Gastroenterology, GlaxoSmithKline, American Gastroenterological Association, Pfizer, and a host of other companies . Dr. Regueiro has served on advisory boards and as a consultant for Abbvie, Janssen, UCB, Takeda, Pfizer, BMS, Organon, Amgen, Genentech, Gilead, Salix, Prometheus, Lilly, Celgene, TARGET Pharma Solutions,Trellis, and Boehringer Ingelheim Pharmaceuticals. Dr. Wolf, Dr. Yim, Dr. Oldfield, and Mr. Newmark have no financial conflicts of interest.

Gastroenterologists in 2023 will have more tools in their arsenal to treat patients with Crohn’s disease or ulcerative colitis. As many as 8-10 adalimumab biosimilars are anticipated to come on the market this year, giving mainstay drug Humira some vigorous competition.

When it comes to prescribing biologics, many physicians rely on ancillary staff for assistance. It’s a team effort to sift through all the paperwork, observed Dr. Oldfield.

“While many community GI practices have specialized staff to deal with prior authorizations, they are still a far cry from the IBD [inflammatory bowel disease] academic centers where there are often pharmacists, nursing specialists, and home-monitoring programs to check in on patients,” he explained.

Landscape on cost is uncertain

At present, little is known about the cost of the biosimilars and impact on future drug pricing, said Dr. Oldfield.

At least for Medicare, Humira biosimilars will be considered Medicare Part D drugs if used for a medically accepted indication, said a spokesperson for the Centers for Medicare and Medicaid Services.

Part D sponsors (pharmacy and therapeutic committees) “will make the determination as to whether Amjevita and other products will be added to their formularies,” said the spokesperson.

Patients never saw a significant cost savings with Remicade biosimilars. “I imagine the same would be true with biosimilars for Humira,” said Dr. Regueiro. Patients may see greater access to these drugs, however, because the insurance plan or the pharmacy plan will make them more readily available, he added.

The hope is that, as biosimilars are introduced, the price of the originator biologic will go down, said Mr. Newmark. “Therefore, we can expect Humira to be offered at a lower price as it faces competition. Where it will sit in comparison to the forthcoming biosimilars will depend on how much biosimilar companies drop their price and how much pressure will be on PBMs and insurers to cover the lowest list price drug,” he said.

AbbVie did not respond to several requests for comment.

Charitable patient assistance programs for biosimilars or biologics can help offset the price of copayments, Mr. Newmark offered.

Ideally, insurers will offer designated biosimilars at a reduced or even no out-of-pocket expense on their formularies. This should lead to a decreased administrative burden for approval with streamlined (or even removal) of prior authorizations for certain medications, said Dr. Oldfield.

Without insurance or medication assistance programs, the cost of biosimilars is prohibitively expensive, he added.

“Biosimilars have higher research, development, and manufacturing costs than what people conventionally think of [for] a generic medication.”

Educating, advising patients

Dr. Oldfield advised that gastroenterologists refer to biologics by the generic name rather than branded name when initiating therapy unless there is a very specific reason not to. “This approach should make the process more streamlined and less subjected to quick denials for brand-only requests as biosimilars start to assume a larger market share,” he said.

Uptake of the Humira biosimilars also will depend on proper education of physicians and patients and their comfort level with the biosimilars, said Dr. Regueiro. Cleveland Clinic uses a team approach to educate on this topic, relying on pharmacists, clinicians, and nurses to explain that there’s no real difference between the reference drug and its biosimilars, based on efficacy and safety data.

Physicians can also direct patients to patient-friendly resources, said Mr. Newmark. “By starting the conversation early, it ensures that when/if the time comes that your patient is switched to or chooses a biosimilar they will feel more confident because they have the knowledge to make decisions about their care.”

The Global Healthy Living Foundation’s podcast, Breaking Down Biosimilars , is a free resource for patients, he added.

It’s important that doctors also understand these products so they can explain to their patients what to expect, said the FDA’s Dr. Yim. The FDA provides educational materials on its website, including a comprehensive curriculum toolkit.

Dr. Hanauer has served as a consultant for AbbVie, Amgen, American College of Gastroenterology, GlaxoSmithKline, American Gastroenterological Association, Pfizer, and a host of other companies . Dr. Regueiro has served on advisory boards and as a consultant for Abbvie, Janssen, UCB, Takeda, Pfizer, BMS, Organon, Amgen, Genentech, Gilead, Salix, Prometheus, Lilly, Celgene, TARGET Pharma Solutions,Trellis, and Boehringer Ingelheim Pharmaceuticals. Dr. Wolf, Dr. Yim, Dr. Oldfield, and Mr. Newmark have no financial conflicts of interest.

Gastroenterologists in 2023 will have more tools in their arsenal to treat patients with Crohn’s disease or ulcerative colitis. As many as 8-10 adalimumab biosimilars are anticipated to come on the market this year, giving mainstay drug Humira some vigorous competition.

Three scenarios will drive adalimumab biosimilar initiation: Insurance preference for the initial treatment of a newly diagnosed condition, a change in a patient’s insurance plan, or an insurance-mandated switch, said Edward C. Oldfield IV, MD, assistant professor at Eastern Virginia Medical School’s division of gastroenterology in Norfolk.

Even with more drugs to choose from, some gastroenterologists may be hesitant to make a switch. “Outside of these scenarios, I would encourage patients to remain on their current biologic so long as cost and accessibility remain stable,” said Dr. Oldfield.

Many factors will contribute to the success of biosimilars. Will physicians be prescribing them? How are biosimilars placed on formularies and will they be given preferred status?  How will manufacturers price their biosimilars? “We have to wait and see to get the answers to these questions,” said Steven Newmark, JD, MPA, chief legal officer and director of policy, Global Healthy Living Foundation/CreakyJoints, a nonprofit advocacy organization based in New York.

Prescribing biosimilars is no different than prescribing originator biologics, so providers should know how to use them, said Mr. Newmark. “Most important will be the availability of patient-friendly resources that providers can share with their patients to provide education about and confidence in using biosimilars,” he added.

Overall, biosimilars are a good thing, said Dr. Oldfield. “In the long run they should bring down costs and increase access to medications for our patients.”

Others are skeptical that the adalimumab biosimilars will save patients much money.

Biosimilar laws were created to lower costs. However, if a patient with insurance pays only $5 a month out of pocket for Humira – a drug that normally costs $7,000 without coverage – it’s unlikely they would want to switch unless there’s comparable savings from the biosimilar, said Stephen B. Hanauer, MD, medical director of the Digestive Health Center and professor of medicine at Northwestern Medicine, Northwestern University, Evanston, Ill.

Like generics, Humira biosimilars may face some initial backlash, said Dr. Hanauer.
 

2023 broadens scope of adalimumab treatments

The American Gastroenterological Association describes a biosimilar as something that’s “highly similar to, but not an exact copy of, a biologic reference product already approved” by the Food and Drug Administration. Congress under the 2010 Affordable Care Act created a special, abbreviated pathway to approval for biosimilars.

AbbVie’s Humira, the global revenue for which exceeded $20 billion in 2021, has long dominated the U.S. market on injectable treatments for autoimmune diseases. The popular drug faces some competition in 2023, however, following a series of legal settlements that allowed AbbVie competitors to release their own adalimumab biosimilars.

“So far, we haven’t seen biosimilars live up to their potential in the U.S. in the inflammatory space,” said Mr. Newmark. This may change, however. Previously, biosimilars have required infusion, which demanded more time, commitment, and travel from patients. “The new set of forthcoming Humira biosimilars are injectables, an administration method preferred by patients,” he said.

The FDA will approve a biosimilar if it determines that the biological product is highly similar to the reference product, and that there are no clinically meaningful differences between the biological and reference product in terms of the safety, purity, and potency of the product. 

The agency to date has approved 8 adalimumab biosimilars. These include: Idacio (adalimumab-aacf, Fresenius Kabi); Amjevita (adalimumab-atto, Amgen); Hadlima (adalimumab-bwwd, Organon); Cyltezo (adalimumab-adbm, Boehringer Ingelheim); Yusimry (adalimumab-aqvh from Coherus BioSciences); Hulio (adalimumab-fkjp; Mylan/Fujifilm Kyowa Kirin Biologics); Hyrimoz (adalimumab-adaz, Sandoz), and Abrilada (adalimumab-afzb, Pfizer).

“While FDA doesn’t formally track when products come to market, we know based on published reports that application holders for many of the currently FDA-approved biosimilars plan to market this year, starting with Amjevita being the first adalimumab biosimilar launched” in January, said Sarah Yim, MD, director of the Office of Therapeutic Biologics and Biosimilars at the agency.

At press time, two other companies (Celltrion and Alvotech/Teva) were awaiting FDA approval for their adalimumab biosimilar drugs.

Among the eight approved drugs, Cyltezo is the only one that has a designation for interchangeability with Humira.

An interchangeable biosimilar may be substituted at the pharmacy without the intervention of the prescriber – much like generics are substituted, depending on state laws, said Dr. Yim. “However, in terms of safety and effectiveness, FDA’s standards for approval mean that biosimilar or interchangeable biosimilar products can be used in place of the reference product they were compared to.”

FDA-approved biosimilars undergo a rigorous evaluation for safety, effectiveness, and quality for their approved conditions of use, she continued. “Therefore, patients and health care providers can rely on a biosimilar to be as safe and effective for its approved uses as the original biological product.”
 

Remicade as a yard stick

Gastroenterologists dealt with this situation once before, when Remicade (infliximab) biosimilars came on the market in 2016, noted Miguel Regueiro, MD, chair of the Digestive Disease and Surgery Institute at the Cleveland Clinic.

Remicade and Humira are both tumor necrosis factor inhibitors with the same mechanism of action and many of the same indications. “We already had that experience with Remicade and biosimilar switch 2 or 3 years ago. Now we’re talking about Humira,” said Dr. Regueiro.

Most GI doctors have prescribed one of the more common infliximab biosimilars (Inflectra or Renflexis), noted Dr. Oldfield.

Cardinal Health, which recently surveyed 300 gastroenterologists, rheumatologists, and dermatologists about adalimumab biosimilars, found that gastroenterologists had the highest comfort level in prescribing them. Their top concern, however, was changing a patient from adalimumab to an adalimumab biosimilar.

For most patients, Dr. Oldfield sees the Humira reference biologic and biosimilar as equivalent.

However, he said he would change a patient’s drug only if there were a good reason or if his hand was forced by insurance. He would not make the change for a patient who recently began induction with the reference biologic or a patient with highly active clinical disease.

“While there is limited data to support this, I would also have some qualms about changing a patient from reference biologic to a biosimilar if they previously had immune-mediated pharmacokinetic failure due to antibody development with a biologic and were currently doing well on their new biologic,” he said.

Those with a new ulcerative colitis or Crohn’s diagnosis who are initiating a biologic for the first time might consider a biosimilar. If a patient is transitioning from a reference biologic to a biosimilar, “I would want to make that change during a time of stable remission and with the recognition that the switch is not a temporary switch, but a long-term switch,” he continued.

A paper that reviewed 23 observational studies of adalimumab and other biosimilars found that switching biosimilars was safe and effective. But if possible, patients should minimize the number of switches until more robust long-term data are available, added Dr. Oldfield.

If a patient is apprehensive about switching to a new therapy, “one may need to be cognizant of the ‘nocebo’ effect in which there is an unexplained or unfavorable therapeutic effect after switching,” he said.

Other gastroenterologists voiced similar reservations about switching. “I won’t use an adalimumab biosimilar unless the patient requests it, the insurance requires it, or there is a cost advantage for the patient such that they prefer it,” said Doug Wolf, MD, an Atlanta gastroenterologist.

“There is no medical treatment advantage to a biosimilar, especially if switching from Humira,” added Dr. Wolf.

Insurance will guide treatment

Once a drug is approved for use by the FDA, that drug will be available in all 50 states. “Different private insurance formularies, as well as state Medicaid formularies, might affect the actual ability of patients to receive such drugs,” said Mr. Newmark.

Patients should consult with their providers and insurance companies to see what therapies are available, he advised.

Dr. Hanauer anticipates some headaches arising for patients and doctors alike when negotiating for a specific drug.

Cyltezo may be the only biosimilar interchangeable with Humira, but the third-party pharmacy benefit manager (PBM) could negotiate for one of the noninterchangeable ones. “On a yearly basis they could switch their preference,” said Dr. Hanauer.

In the Cardinal Health survey, more than 60% of respondents said they would feel comfortable prescribing an adalimumab biosimilar only with an interchangeability designation.

A PBM may offer a patient Cyltezo if it’s cheaper than Humira. If the patient insists on staying on Humira, then they’ll have to pay more for that drug on their payer’s formulary, said Dr. Hanauer. In a worst-case scenario, a physician may have to appeal on a patient’s behalf to get Humira if the insurer offers only the biosimilar.

Taking that step to appeal is a major hassle for the physician, and leads to extra back door costs as well, said Dr. Hanauer.

Humira manufacturer AbbVie, in turn, may offer discounts and rebates to the PBMs to put Humira on their formulary. “That’s the AbbVie negotiating power. It’s not that the cost is going to be that much different. It’s going to be that there are rebates and discounts that are going to make the cost different,” he added.

As a community physician, Dr. Oldfield has specific concerns about accessibility.

The ever-increasing burden of insurance documentation and prior authorization means it can take weeks or months to get these medications approved. “The addition of new biosimilars is a welcome entrance if it can get patients the medications they need when they need it,” he said.

PARIS – Two tyrosine kinase inhibitors (TKI) used in the treatment of chronic myeloid leukemia (CML) – nilotinib (Tasigna) and ponatinib (Iclusig) – may cause atherosclerotic arterial diseases. This common side effect, which has even been seen in patients without cardiovascular risk factors, has gone unnoticed in clinical trials. So what can be done to prevent it?

Cardiologist Gabrielle Sarlon, MD, PhD, a professor at Marseille (France) University Hospital, offered her recommendations at the European Days of the French Society of Cardiology Conference 2023.

In the literature, we find many hypotheses that seek to explain why these drugs bring about the formation of atheromatous plaque. The findings of one French study led Dr. Sarlon to state, “I firmly believe that, in some patients, these treatments make LDL cholesterol go up.” This would be the main cause of the coronary and peripheral arterial diseases that are being seen.

Therefore, “LDL-C should start being monitored when the therapy starts, and a statin may have to be prescribed,” she said.

Arterial diseases

By bringing about a marked improvement in patients’ chances of survival, TKIs “have revolutionized the management of chronic myeloid leukemia,” Dr. Sarlon added. But these treatments have side effects. The most common is high blood pressure, “an effect that attests to the efficacy of targeted therapies and that must be quickly treated” with antihypertensives.

It is well known that the targeted therapies cause the rise in blood pressure. What was unexpected, though, was the vascular toxicity seen with the latest generation of TKIs. “This is a real toxicity that we need to know about, detect, and manage,” said Dr. Sarlon.

The prevalence of arterial diseases induced by nilotinib, a second-generation TKI, can be as high as 10%. Single-center studies have indicated much higher numbers. In a small study that Dr. Sarlon and her team conducted at Marseille University Hospital, atherosclerotic-type arterial injuries were observed in more than 30% of patients treated with nilotinib.

Dr. Sarlon noted that the signs of arterial toxicity occurring with this treatment have not appeared in clinical trials. Observations of the real-life use of nilotinib led French and German teams to sound the alarm. They noticed that some patients treated for CML had developed claudication and progression to critical limb ischemia of the lower extremities.

Risk factors uncovered

The first retrospective analysis to explore this risk was carried out by a German team. They included 179 patients who received nilotinib and found that 11 (6.2%) developed severe and previously unrecognized lower-extremity peripheral arterial disease (PAD) that required invasive therapy. The mean time from initiation of nilotinib to the first PAD event was 105.1 weeks (range = 16-212 weeks).

The following have emerged as major risk factors for nilotinib-induced PAD: the presence of cardiovascular risk factors, age older than 60 years, and long duration of exposure to nilotinib. Some of these factors were confirmed in the more recent study conducted at Marseille University Hospital involving patients treated with nilotinib. According to other research, there seems to be a correlation between this risk and the dose administered.

In the case of ponatinib, the side effects are even more common – so much so that, a few months after this third-generation TKI was authorized, a warning was issued about its use. A long-term follow-up study reported a 28% prevalence of cardiovascular events, while arterial diseases were observed in 20% of cases after 1-2 years on the treatment.

In terms of pathophysiology, the Marseilles University Hospital study found that arterial injuries were associated with stenosis greater than 50% in almost half of cases. “The atheromatous plaques were found where they typically are,” with the carotid bulb being the most involved territory, according to the researchers. But they’re also found in other arteries – femoral, vertebral, even renal – “sometimes in patients without cardiovascular risk factors.”

One distinctive characteristic to keep in mind is that “lipid-rich atheromatous plaques appear very dark on imaging” and thus can go unnoticed during a Doppler ultrasound. And, Dr. Sarlon added, “surprisingly, the thickening can extend to the external carotid artery.”

Ankle-brachial index

Published last year, the first European Society of Cardiology Guidelines on Cardio-Oncology present specific baseline risk-assessment and monitoring recommendations regarding patients treated with nilotinib and ponatinib. One suggests that a cardiovascular risk assessment be done every 3 months during the first year and every 6-12 months thereafter. This assessment would include such items as ECGs, blood pressure measurements, and lipid profile tests.

In addition, it is advised that every 6 months an ankle-brachial index test be performed to check for PAD. At Marseille University Hospital, a Doppler ultrasound is also done at each follow-up appointment to look for arterial plaques, “even for patients at low risk for cardiovascular disease,” said Dr. Sarlon. “It seems, above all, absolutely necessary that hematologists order an LDL-C test and, if needed, consider statin therapy,” all the while keeping in mind that “the target LDL-C level is 1 gram per liter.”

At Marseille University Hospital, a Doppler ultrasound is also done at each follow-up appointment to look for arterial plaques, “even for patients at low risk for cardiovascular disease,” said Dr. Sarlon. “It seems, above all, absolutely necessary that hematologists order an LDL-C test and, if needed, consider statin therapy,” all the while keeping in mind that “the target LDL-C level is 1 gram per liter.”

In January 2022, Anthony Arenz, a 51-year-old living in Mesa, Ariz., breathed a small sigh of relief.

The Galleri blood test, which screens for 50 types of cancer, hadn’t detected any positive signs.

It would be welcome news to anyone but especially to a firefighter with a 9% greater risk of developing cancer and a 14% greater risk of dying from it than the average person. The Mesa unit had lost two servicemen to cancer in the past 3 years. Both were more than a decade younger than Mr. Arenz.

When the city of Mesa offered additional free screening – including a full-body MRI – to firefighters over 50, Mr. Arenz initially shrugged it off. With a negative Galleri test in hand, he didn’t want to spend more time dwelling on it.

Still, he began to feel a creeping guilt for skipping a test that many of his fallen colleagues hadn’t been offered. He tried to soothe his anxiety with research. A look through the company’s website didn’t set him at ease. According to Grail Bio, a test result of “no cancer signal detected” does not rule out cancer.

Mr. Arenz booked his free MRI.

The results left him heavy: stage I kidney cancer. The Galleri test had missed it.

Mr. Arenz received his free Galleri test through a cancer screening program funded by the city of Mesa. The program is housed at Vincere Cancer Center in Scottsdale, Ariz. Under the leadership of radiation oncologist and Vincere co-owner Vershalee Shukla, MD, the program currently screens first responders in more than 10 Arizona cities at no cost to them.

Vincere began using Galleri shortly after the test launched for consumers in June 2021. Since then, the first responder program has become the largest commercial user of the test in North America.

But the ability of the Galleri test to identify cancer and, perhaps more importantly, the fallout from erroneous results have been under scrutiny since the test’s launch. The Galleri test, which has not yet been approved by the Food and Drug Administration, is so new that few know what incorrect results look like in practice and how often they might occur.

After running the test on about 2,000 servicemen and servicewomen, Dr. Shukla can offer some insight about the test’s real-world value in a high-risk population.

“Cancer screening is a very complicated issue,” Dr. Shukla said in an interview. “Being honest, the tests are good but are not ready yet [for wider use].”

Mr. Arenz was not the only firefighter who got a surprise after taking a Galleri test.

In nearby Phoenix, 51-year-old firefighter Mike Curtis knew his risk for cancer was high, but he wasn’t that worried. Mr. Curtis had been running into fires since he was 17. His dad, also a firefighter, had died of cancer at age 58.

Mr. Curtis had taken the Vincere Cancer Center up on every free screening service since the program began in late 2018 – well before Dr. Shukla started using Galleri in 2021. His most recent lung CT was clear. But he underwent the Galleri test just to stay vigilant.

His result was a shock. The test detected signs of cancer.

Mr. Curtis decided to tell no one, not even his wife. He’d bear the bad news alone until he was certain.

Dr. Shukla, however, immediately doubted the blood test result. She expedited several follow-up tests. One week, a PET, and CT of the abdomen and pelvis later, her hunch was confirmed. The Galleri test result was wrong, Mr. Curtis did not have cancer.

The price of his peace of mind: an extensive workup with a $4,000 price tag. Fortunately, the bill was covered by the screening program.

Overall, in just over 18 months of using the blood test, Dr. Shukla has only encountered 1 other false positive out of about 2,000 Galleri results.

She also discovered two positive signals for cancer using Galleri that were confirmed with follow-up tests. One was a chordoma, a rare type of bone cancer, and the other was a squamous cell carcinoma of the head and neck. The Galleri test caught both remarkably early, in time for treatment.

For Dr. Shukla, however, false negatives were particularly “horrible.” Mr. Arenz’s was just 1 of 28 cancers that the blood test missed. And because 500 negative tests are yet to be validated, the 28 false negatives may be an underestimate.

In her experience, the binary test result – a simple positive or negative cancer signal – is an oversimplification of risk, she said. It “gives a false perception that you have cancer or you don’t,” although the test itself is not definitive.

Grail senior medical director Whitney Jones, MD, agreed that the test is not meant to be a stand-alone screening test for cancer. The purpose of the Galleri test is to “complement other screenings, not replace them,” Dr. Jones told this news organization.

According to an analysis of Galleri data and Dr. Shukla’s experience, the test’s specificity was over 99%. That means the test successfully minimizes false positives.

But the test’s sensitivity was much lower. From data from first responders, Dr. Shukla determined the sensitivity to be 6.7%. That means the test misses about 93 of every 100 cancers. According to Grail’s latest data from more than 6,300 people older than 50, the test’s sensitivity was 29%.

Specificity and sensitivity are metrics used to credential a test and establish confidence in its ability to detect the target disease. A test with high specificity can correctly identify patients who do not have the condition in question, while a test with high sensitivity can correctly identify patients who do have the disease. But there are trade-offs between sensitivity and specificity. One value is increased at the expense of the other.

It’s normal for a cancer screening test to prioritize specificity, according to Aparna Parikh, MD, an oncologist at Mass General Cancer Center in Boston. In a test like Galleri, which is meant to be an adjunct to other screening modalities, “at least we are seeing a good specificity, which is important, because we don’t want false positives, where the downstream impact on the patient can be high.”

Overall, Dr. Jones said, Grail Bio’s aim is to build a test that’s sensitive enough to catch the most dangerous cancers without inundating the healthcare system with false positives. In addition, Dr. Jones explained, sensitivity varies by cancer type. It tends to be lower for cancers for which other screening modalities are available, as well as for earlier-stage disease.

However, the Galleri sensitivity values are “a little bit scary,” said Ji-Hyun Lee, DrPH, professor of biostatistics at the University of Florida and director of the division of quantitative sciences at the University of Florida Health Cancer Center, both in Gainesville. Dr. Lee, who is not affiliated with Grail, reviewed the company’s publicly available data as well as Dr. Shukla’s data at the request of this news organization.

While there’s no definitive threshold for sensitivity, miss rates as high as 93% and 71% “provide little confidence in the [accuracy of the] test,” Dr. Lee said.

Positive and negative predictive values, however, are more clinically relevant measures of a screening test. These numbers indicate how likely it is that a patient’s results are true and therefore how worried they should be about a positive result and how much they should trust a negative result.

Galleri’s data in the over-50 population and Dr. Shukla’s in first responders suggest the test’s negative predictive value is very high – 98.6% and 98.1%, respectively – which means most people can trust a negative test result.

The positive predictive value, however, was less straightforward. In first responders, Dr. Shukla found that only half of positive Galleri tests were confirmed cases of cancer. And an analysis of Grail’s data found that only 38% of positive Galleri tests – 35 of 92 tests – represented a validated cancer diagnosis.

“In a clinical setting, positive predictive value is more usable for decision-making for the patient,” said Dr. Lee. “Positive predictive value isn’t always high, because everything doesn’t always transfer perfectly to the clinic.” But in the general population, if only 38% of patients with positive Galleri results truly have cancer, the test is “not quite useful to make a decision for the patient or the providers.”

Galleri may also be a costly prospect for patients, no matter the result, cautioned Electra Paskett, PhD, an epidemiologist and cancer screening expert at Ohio State University, Columbus. A positive Galleri test leads to a cascade of follow-up diagnostic tests, which payers may not cover. For a negative result, Galleri recommends that the patient undergo screening again in a year, at an annual cost of $950 plus the cost of any follow-up testing when Galleri does pick something up.

“If a provider wants to offer the Galleri test, all those things need to be made abundantly clear, in my opinion,” Dr. Paskett said.

Following the negative Galleri test, Mr. Arenz’s cancer didn’t slip through the cracks because he received other advanced imaging free of charge. But whether all doctors will go to such lengths to back up Galleri results, even for patients with negative results, is unknown.

A negative result can give patients “a huge false sense of security,” said Dr. Shukla. And if a test is positive, the workup isn’t simple. Chasing cancer, especially one that’s not really there, can be nerve-wracking and expensive.

The question, then, is why perform the Galleri test at all if results require so much validation?

Dr. Parikh explained that a high-risk group such as firefighters represents an ideal-use case for Galleri and other liquid biopsy tests. But she noted that she would be “wary of the ability of the system to manage this test en masse” were the test to be used more widely in the general population.

Dr. Shukla said it’s less about the results she’s getting today and more about making the test more effective for her patients in the future. First responders need a test such as this that can quickly identify multiple cancers. However, to improve the test, Grail needs more data from this high-risk population. That’s what she’s after.

Mr. Curtis doesn’t regret taking the Galleri test. The emotional toll of thinking he had cancer for a few days wasn’t too high a price, in his opinion. It’s part of cancer screening. But he acknowledged that it would have been a much more burdensome experience had he’d been financially responsible for the workup or if he hadn’t had Dr. Shukla to manage his case from start to finish.

Because it was free, Mr. Arenz doesn’t regret undergoing the Galleri test either. But he tells his coworkers to check the site, do their research, and get more screening.

“Any medical center that’s just doing this one test, you just have to be careful,” Dr. Shukla said. “It’s not that easy.”
