Pharmacogenomic testing for antidepressants could help reduce the time and cost it takes to find the most effective medication for a patient, according to a new study.

Scientists developed a microsimulation model to evaluate the effectiveness of pharmacogenomic testing for adult patients in British Columbia, with newly diagnosed moderate to severe major depressive disorder (MDD). The model predicted that testing could result in 37% fewer patients developing refractory depression, 15% more time of patients feeling well, and a health system cost-savings of $956 million CAD over 20 years.

“Our study shows that, if pharmacogenomic testing guides the prescription of an effective antidepressant, it can reduce the lengthy trial-and-error process many patients experience and dramatically reduce the financial burden on the health care system,” Shahzad Ghanbarian, PhD, the lead author and a research analyst at the University of British Columbia’s Centre for Clinical Epidemiology and Evaluation, Vancouver, said in an interview.

“The next step should be developing implementation strategies and identifying the most suitable health care professionals to provide pharmacogenomic-guided care,” she said.

The study was published online on in the Canadian Medical Association Journal.
 

Developing a model

The World Health Organization has predicted that depression will be the leading cause of disability worldwide by 2030. However, about half of patients don’t respond to the antidepressant that they are initially prescribed, and more than one-quarter report adverse effects. Previous studies have found that up to 42% of the lack in response stems from genetic factors that affect medication metabolism.

Pharmacogenomic testing, which uses a blood, saliva, or buccal swab sample, could help identify genetic variants involved in drug metabolism and response as well as guide prescribing and reduce adverse effects, the authors wrote.

Dr. Ghanbarian and colleagues developed a microsimulation model in collaboration with patient partners, clinicians, and the health system to evaluate the effectiveness and cost-effectiveness of pharmacogenomic testing for adult patients with MDD in British Columbia. The model included unique patient characteristics, such as metabolizer phenotypes, and followed the experience of patients through diagnosis, treatment, and recurrence.

According to British Columbia administrative data from 2015 to 2020, the model simulated a population of 194,149 adults and incorporated 40 different antidepressants and other treatments, including electroconvulsive therapy (ECT) and psychotherapy. The research team compared treatment pathways for patients with and without pharmacogenomic testing over 20 years.

Overall, the model showed that pharmacogenomic-guided treatment resulted in higher remission rates and lower discontinuation rates, with 23,216 (37%) fewer patients developing refractory depression and decreased use of resource-intensive treatment options such as ECT and psychotherapy (by 28% and 22%, respectively). According to the model, these reductions would save the British Columbia health system $4,926 CAD per patient, or about $56 million CAD over 20 years.

These findings provide a solid economic justification for clinical implementation of pharmacogenomic-guided depression treatment in Canada.

In addition, the model found that patients who underwent pharmacogenomic testing spent 15% more time in the “well” state without depression symptoms and 18% less time in the MDD state with recurrent episodes or refractory depression. In turn, this would mean 1,869 fewer deaths and 21,346 fewer all-cause hospital admissions over 20 years.

Pharmacogenomic testing also led to gains of 0.064 life-years and 0.381 quality-adjusted life-years per patient, or 12,436 life-years and 74,023 QALYs for all of British Columbia over 20 years.

From a cost perspective, the $121 million CAD cost of pharmacogenomic testing and $524 million CAD increase in episodic care were offset by a decrease in the cost of refractory MDD care. In sensitivity analyses, up-front investment in pharmacogenomic testing was typically offset after 2 years through lower direct medical costs, and it was also considered a cost-saving measure from that point forward.

“By incorporating the perspectives of patients with lived and living experience into this model, alongside robust data sets, we were able to carefully simulate the treatment journey of people with major depression,” Dr. Ghanbarian said. “The simulation model is designed to be flexible and could be applied to other jurisdictions beyond British Columbia, where we might expect to see similar benefits, particularly within a comparable Canadian context.”
 

Implementing the model

Now, Dr. Ghanbarian and colleagues are interested in potential implementation strategies at a system-wide level. For now, pharmacogenomic tests aren’t offered through the public health systems across Canada, but patients can pay for them through private companies.

“These findings provide a solid economic justification for clinical implementation of pharmacogenomic-guided depression treatment in Canada,” Chad Bousman, PhD, associate professor of physiology and pharmacology at the University of Calgary (Alta.), said in an interview.

Dr. Bousman, who was not involved with this study, coauthored the Clinical Pharmacogenetics Implementation Consortium guideline for several genotypes and serotonin reuptake inhibitor antidepressants. He and colleagues have also developed and evaluated web-based tools that translate pharmacogenetic data into evidence-based prescribing recommendations.

“The hope is that this work will facilitate investment in the establishment of the necessary infrastructure to ensure Canadians have equitable access to pharmacogenomic testing and ultimately improve mental health outcomes,” he said.

The study was funded by Genome BC, Genome Canada, and Michael Smith Health Research British Columbia. Dr. Ghanbarian and Dr. Bousman reported no relevant financial relationships.

Maternal depressive symptoms probably start at or before pregnancy, with trajectories that remain stable across the perinatal into the postnatal period, new research suggests.

The analysis of more than 11,000 pregnant women with depressive symptoms from seven prospective cohorts in Canada, the United Kingdom, and Singapore suggests that depressive symptoms (low, mild, or high levels) start sooner and last longer than is commonly thought.

The term “postnatal depression” is “at odds with existing scientific literature and the experience of clinicians who treat mental disorders in the context of obstetric practice,” said Michael J. Meaney, PhD, professor at McGill University, Montreal, and director of the Translational Neuroscience Program at the Agency for Science, Technology and Research (A*STAR), Singapore. 

“Although we anticipated that the prenatal period would be the primary time of onset and that symptom levels would be largely stable, I was nevertheless surprised at how this pattern was so universal across so many studies,” he said in an interview. “In truth, we saw very little evidence for a postnatal onset.”

This suggests that depressive symptoms start earlier than previously thought, and “that the relevant clinical settings for prevention are those treating women in routine health care, including family medicine,” he added.
 

Start screening sooner 

The investigators examined the course and stability of self-reported depressive symptoms at multiple time points across the perinatal period among 11,563 pregnant women in seven cohorts from the United Kingdom, Canada, and Singapore. Participants’ mean age was 29 years; 87.6% were White, 4.9% were East Asian, and 2.6% were Southeast Asian. 

The analysis tracked depressive symptoms from preconception through pregnancy to 2 years after childbirth. Three groups of mothers were identified in each cohort on the basis of their level of depressive symptoms (low, mild, or high) as assessed by the Edinburgh Postnatal Depression Scale (EPDS) or the Center for Epidemiological Studies Depression (CES-D).

The team found that all mothers within and across all cohorts had stable trajectories of maternal depressive symptoms from pregnancy onward. Trajectories for mothers who passed clinically validated cutoffs for “probable” depression also showed stable trajectories from pregnancy into the postnatal period.

“Taken together, these findings suggest that maternal depressive symptom levels in community-based cohort studies are apparent during pregnancy and remain stable into the postnatal period,” the authors write. “The results point to the early antenatal period as a timepoint for the identification of stable trajectories of maternal depressive symptoms. Public health policies should emphasize the early antenatal period as the optimal timing for interventions targeting maternal depressive symptoms.”

The findings, they note, “underscore the American Psychiatric Association’s recent approach in renaming postpartum depression as peripartum depression.”

Furthermore, a recent paper of the group’s findings details that depressive symptoms may often predate conception. 

“Our findings should serve to universally align practice to prenatal screening,” even though depression screening often takes place in a mid-gestational visit during the second trimester, Dr. Meaney said. “Our findings and those on the effects on child development strongly suggest the timing of the screening must be advanced into the first confirmation of pregnancy.” 
 

Depression is likely worse in the United States

Catherine Monk, PhD, chief of the Division of Women’s Mental Health and professor of medical psychology at Columbia University, Vagelos College of Physicians and Surgeons, New York, said in an interview that the results of the study “amplify similar research findings and the experience of most perinatal clinicians: Depression is stable from pregnancy onwards.”

John Abbott/Columbia University

Dr. Monk, who was not involved in the research, said that “as the authors note, the common focus on postpartum depression misses the months of prior suffering and an opportunity for earlier intervention.” Dr. Monk said she would have liked the results to have been examined further by race and ethnicity and socioeconomic factors. “Also, the combined sample does not include a U.S. cohort. This is significant as the U.S. has the highest maternal morbidity and mortality rate of developed nations, and some reports identify mental health factors as the number-one cause of maternal mortality.”

“Given the tremendous economic, racial, and ethnic inequities in health care – the lack of any kind of health justice – it is quite possible that in the U.S., depression that starts in pregnancy worsens over time, at least for some demographic groups,” Dr. Monk said. “Rates of depression, levels of depression, and the course of it during the peripartum period may be even more dire [in the U.S.] than what is represented in this article.” “What should be practice-changing about this article, and so many others demonstrating the persistent and often high levels of life-threatening depression during pregnancy, is the need for mental health providers to advocate for changes to the low rates of insurance reimbursement that push providers away from accepting insurance and into private practice, making access to affordable mental care nearly impossible for most,” she concluded. 

This study was supported by the Singapore Institute for Clinical Sciences, Agency for Science, Technology, and Research; the Toxic Stress Network of the JPB Foundation; the Hope for Depression Research Foundation; and the Jacob’s Foundation. Dr. Meaney and Dr. Monk report no conflicts of interest.

Headache and headache associated with mood disorders are common among individuals from the LGBTQIA+ community, but preconceptions should be abandoned in a diverse population fearful that their gender identity or sexual orientation will lead to mistreatment.

It is “important not to assume that just because someone is a member of the LGBTQ+ community they will need psychiatric or behavioral health support,” said Maya A. Marzouk, PhD, division of behavioral medicine and clinical psychology, Cincinnati Children’s Hospital Medical Center.

Instead, it is useful not to make any assumptions. There is a potential association between minority status and headache susceptibility, but it is more reasonable initially to address the diagnosis and treatment of headache in LGBTQIA+ patients the same way it is addressed in any other patient, Dr. Marzouk said at the 2023 Scottsdale Headache Symposium.

The acronym to describe individuals with gender identities different from male and female and sexual orientations not limited to heterosexuality has been in almost constant evolution over several decades. An addition sign that accompanies LGBTQIA refers to those who do not identify with any letters in the acronym (lesbian, gay, bisexual, transsexual, queer/questioning, intersex, and asexual).
 

Take steps to normalize the interaction

Although many clinicians have been acclimated to these diverse identifies, not all have risen above preconceptions that become obstacles to effective care, according to Dr. Marzouk. In the context of headache management, Dr. Marzouk emphasized the need to be respectful of the range of gender identities and sexual orientations and to take steps to normalize the interaction.

For example, Dr. Marzouk advised using gender-neutral language at the start of each patient encounter and ask open-ended questions about gender, sexual identify, and pronouns to avoid patient discomfort from misidentification. In turn, the clinicians can establish their own gender identification and preferred pronouns to reinforce the idea that doing so is normal behavior.

This change in approach should be made “for all patients. Do not try to guess who needs them,” she said.

Intake forms and office atmosphere, such as signs and images, should also be welcoming to all patients, she added. Rather than trying to make adjustments for a LGBTQIA+ visit, Dr. Marzouk said a uniform approach helps normalize the experience of LGBTQIA+ patients without singling them out.

Despite the effort to provide an open and welcoming environment, Dr. Marzouk acknowledged that mistakes are difficult to avoid for those with limited experience serving the LGBTQIA+ community. When mistakes are made, she advised clinicians to immediately acknowledge the mistake and ask for guidance from the patient.

The potential offense is making the patient feel “other” or abnormal.
 

A higher rate of migraine

The interactions that LBGTQIA+ patients have with others outside their community is a possible explanation for the substantial rate of headache as well as headache with comorbid psychiatric disorders in this population.

In a survey published in 2020, the rate of migraine was 19.7% in heterosexual women, 26.7% in lesbians, and 36.8% in bisexual women. Among men, it rose from 9.8% in heterosexuals to 14.8% in gays and then to 22.8% in bisexuals.

Migraine relative to headache is also associated with more mood disorders among LGBTQIA+ individuals. In a study published in 2022, LGBTQIA+ patients with migraine relative to those with headache were more likely to have depression (46.4% vs. 22.3%; P < .001), anxiety (72.1% vs. 51.6%; P < .001), and posttraumatic stress disorder (37.5% vs. 21.4%; P < .001).
 

A vicious cycle of underdiagnosis and undertreatment

These associations are consistent with minority stress theory, according to Dr. Marzouk. This theory postulates that the associated stress of discrimination, rejection, and microaggressions, such as explicit efforts to make LGBTQIA+ individuals to feel “other,” produces epigenetic changes and dysregulation of the hypothalamic-pituitary-adrenal axis. In turn, this plays a role in the pathogenesis of migraine.

The inconsistency with which minority stress affects LGBTQIA+ patients might be due to relative differences in social support, coping skills, an innate resilience to these effects, Dr. Marzouk explained.

Dr. Marzouk characterized the LGBTQIA+ community as “underserved” for treatment of headache. She suggested that medical mistrust and self-blame among LGBTQIA+ individuals might be factors contributing to a vicious cycle of underdiagnosis and undertreatment. Efforts by the medical community to reach out to the LGBTQIA+ community are appropriate to address an unmet need.

“Individuals with psychiatric comorbidities may experience even more benefit from migraine care,” she said.
 

Clinical studies should be more inclusive

While agreeing in principle with these remarks, Eric A. Kaiser, MD, PhD, department of neurology, University of Pennsylvania, Philadelphia, said that this area would be better advanced if studies routinely included patients with diverse-gender identities and sexual orientations. Speaking about how to organize these studies, Dr. Kaiser suggested that enrollment criteria should explicitly seek these individuals and that these differences should be captured in the baseline characteristics.

“For example, gender options could include man, woman, non-binary, gender diverse, gender nonconforming, or gender nonspecified,” he said.

To close “the significant knowledge gap that exists in managing headache disorders in sexually- and gender- diverse people,” Dr. Kaiser said that clinical research studies, like patient treatment of diverse populations, “should be conducted with welcoming and affirming practices.”

Dr. Marzouk reported no potential conflicts of interest. Dr. Kaiser reported financial relationships with Amgen and Lundbeck.

Headache and headache associated with mood disorders are common among individuals from the LGBTQIA+ community, but preconceptions should be abandoned in a diverse population fearful that their gender identity or sexual orientation will lead to mistreatment.

It is “important not to assume that just because someone is a member of the LGBTQ+ community they will need psychiatric or behavioral health support,” said Maya A. Marzouk, PhD, division of behavioral medicine and clinical psychology, Cincinnati Children’s Hospital Medical Center.

Instead, it is useful not to make any assumptions. There is a potential association between minority status and headache susceptibility, but it is more reasonable initially to address the diagnosis and treatment of headache in LGBTQIA+ patients the same way it is addressed in any other patient, Dr. Marzouk said at the 2023 Scottsdale Headache Symposium.

The acronym to describe individuals with gender identities different from male and female and sexual orientations not limited to heterosexuality has been in almost constant evolution over several decades. An addition sign that accompanies LGBTQIA refers to those who do not identify with any letters in the acronym (lesbian, gay, bisexual, transsexual, queer/questioning, intersex, and asexual).
 

Take steps to normalize the interaction

Although many clinicians have been acclimated to these diverse identifies, not all have risen above preconceptions that become obstacles to effective care, according to Dr. Marzouk. In the context of headache management, Dr. Marzouk emphasized the need to be respectful of the range of gender identities and sexual orientations and to take steps to normalize the interaction.

For example, Dr. Marzouk advised using gender-neutral language at the start of each patient encounter and ask open-ended questions about gender, sexual identify, and pronouns to avoid patient discomfort from misidentification. In turn, the clinicians can establish their own gender identification and preferred pronouns to reinforce the idea that doing so is normal behavior.

This change in approach should be made “for all patients. Do not try to guess who needs them,” she said.

Intake forms and office atmosphere, such as signs and images, should also be welcoming to all patients, she added. Rather than trying to make adjustments for a LGBTQIA+ visit, Dr. Marzouk said a uniform approach helps normalize the experience of LGBTQIA+ patients without singling them out.

Despite the effort to provide an open and welcoming environment, Dr. Marzouk acknowledged that mistakes are difficult to avoid for those with limited experience serving the LGBTQIA+ community. When mistakes are made, she advised clinicians to immediately acknowledge the mistake and ask for guidance from the patient.

The potential offense is making the patient feel “other” or abnormal.
 

A higher rate of migraine

The interactions that LBGTQIA+ patients have with others outside their community is a possible explanation for the substantial rate of headache as well as headache with comorbid psychiatric disorders in this population.

In a survey published in 2020, the rate of migraine was 19.7% in heterosexual women, 26.7% in lesbians, and 36.8% in bisexual women. Among men, it rose from 9.8% in heterosexuals to 14.8% in gays and then to 22.8% in bisexuals.

Migraine relative to headache is also associated with more mood disorders among LGBTQIA+ individuals. In a study published in 2022, LGBTQIA+ patients with migraine relative to those with headache were more likely to have depression (46.4% vs. 22.3%; P < .001), anxiety (72.1% vs. 51.6%; P < .001), and posttraumatic stress disorder (37.5% vs. 21.4%; P < .001).

Breast cancer has a worse prognosis when diagnosed during pregnancy or postpartum. Methods for early detection are needed, as evidenced every day in the multidisciplinary unit for treating pregnancy-associated breast cancer, which operates within the breast unit at the Vall d’Hebron University Hospital in Barcelona.

The team working in this field is led by Cristina Saura, PhD, who is also head of the Breast Cancer Group at the Vall d’Hebron Institute of Oncology (VHIO). The results of a study recently published in Cancer Discovery show, for the first time, that breast milk from breast cancer patients contains circulating tumor DNA that can be detected by a liquid biopsy of the milk.

Dr. Saura explained in an interview why they began to pursue this research, which, in one sense, fell into their laps. “In this case, it arose from the concerns of a breast cancer patient who was diagnosed while pregnant with her third daughter. She was actually the one who came up with the idea for the project. She was worried that she had transmitted the tumor through her breast milk to her second daughter while breastfeeding. She had been breastfeeding for a long time and had stretched it out until shortly before she was diagnosed with breast cancer. So she brought us a sample of breast milk that she had stored in her freezer.

“So, thanks to her, that’s where our project started. Though we knew that breast cancer is not transmitted through breast milk, we decided to test the sample and look for markers that could help our research. In the end, when we analyzed the patient’s breast milk, we found DNA with the same mutation that was present in her tumor,” explained Dr. Saura. She noted that the breast milk they analyzed had been frozen for more than a year before the patient’s cancer diagnosis.

In terms of methodology, Ana Vivancos, PhD, head of the VHIO cancer genomics group and also one of the authors of the study, explained that they used two techniques to analyze the breast milk and blood samples: next-generation sequencing and droplet digital polymerase chain reaction. These methods confirmed the presence of ctDNA in the breast milk.
 

High-sensitivity genomic panel

“We were able to detect tumor mutations in milk samples from 13 of the 15 patients with breast cancer who were tested, while circulating tumor DNA was detected in only one of all the blood samples that were collected at the same time,” said Dr. Vivancos. “The samples from the two patients for whom no mutation was detected were discovered to be colostrum that had been collected during the first few hours of lactation.”

As a next step to make this finding practically useful, the research team designed a genomic panel using next-generation sequencing as a potential method for early detection of breast cancer. “We’ve developed a panel that uses hybrid capture chemistry and unique molecular identifiers that ensure better sensitivity during next-generation sequencing. The panel has been calibrated, based on the existing literature, to detect the genes that are most frequently mutated in breast cancer in young women under 45 years old.”

According to Dr. Vivancos, the sensitivity of this panel exceeds 70%. This means that for all the patient samples analyzed using this panel, 7 out of 10 cases are detected with 100% specificity.

“In practice, the panel design allows us to detect mutations in more than 95% of breast cancer cases in women under 45 years old. Therefore, using this panel for early detection of this type of tumor during lactation should contribute to addressing a medical need that, until today, has gone unmet,” noted Dr. Vivancos.

As for this unresolved need, Dr. Saura explained that there is currently no system or tool available to allow early suspicion of breast tumors in pregnant women prior to diagnosis. “That’s exactly the goal of this research: to screen for breast cancer in women who have just given birth. Now, it needs to be validated in a larger group of women in a clinical trial.”
 

More direct contact with tumor cells

In Dr. Saura’s opinion, in Spain, just like taking a small blood sample from newborns in a heel-prick test to rule out metabolic diseases, milk samples could be taken from women who give birth to rule out or diagnose breast cancer.

As to the potential advantages that breast milk liquid biopsy could have over similar techniques like blood liquid biopsy, Dr. Vivancos pointed to the results of her study: “We have seen that breast milk liquid biopsy was positive for the presence of circulating tumor DNA in 87% of cases, whereas blood only revealed the presence of this marker in 8% of cases. This difference indicates that breast milk is a biofluid that is in more direct contact with tumor cells and therefore will be more informative in earlier stages.”

Dr. Saura explained that the data does not lie when it comes to these tumors in pregnant or postpartum women. “In general, they tend to have a worse prognosis because, in most cases, they are diagnosed in advanced stages. Furthermore, it is typically assumed that the physiological changes in the breasts during gestation and lactation, which are considered to be normal, may hide a developing tumor. The fact is that postpartum breast cancer, understood to be the 10 years after delivery, accounts for 40%-45% of breast cancer cases diagnosed before age 45.”

The researchers plan to continue this project. “Our next step to confirm the usefulness of breast milk as a new tool for liquid biopsy for early detection of breast cancer during the postpartum period is to perform this noninvasive test in thousands of women,” said Dr. Saura.
 

Goal: Standardize the test as a screening method

“Based on the results we’ve published, we’re starting a study aimed at collecting breast milk samples from 5,000 healthy women around the world who became pregnant at age 40 or older, or who got pregnant at any age and carry mutations that increase their risk of breast cancer,” Dr. Saura added.

When asked when they expect to have preliminary results from this new study, Dr. Saura stated that it’s not yet possible to say exactly when. “We’re still waiting for funding to continue this project, but we continue performing analyses on a case-by-case basis. Of course, if we detect any abnormalities in these women, we will follow the established protocol to confirm diagnosis and start treatment if necessary.”

When asked whether it is reasonable to expect breast milk liquid biopsy to become normalized as a screening method for women of childbearing age who have a history or risk factors for developing breast cancer, Dr. Vivancos said, “That’s the scenario we see in the future and what we wish to contribute toward by providing scientific evidence to make it a reality.”

“For now, our goal is to validate whether circulating tumor DNA can be detected by breast milk liquid biopsy even before breast cancer can be diagnosed using conventional imaging techniques. If we can validate these preliminary results, we will be able to detect breast cancer early using a noninvasive test like breast milk liquid biopsy,” explained Saura.

Lastly, and in view of the issues that are still unresolved when it comes to the detection and treatment of breast cancer during pregnancy, Dr. Saura highlighted the emotional impact that a diagnosis of pregnancy-related cancer has on women and on those close to them. “But the first thing they need to know is that diagnosis is not necessarily synonymous with termination of the pregnancy. On the contrary, this tumor can be treated during pregnancy, since surgery can be performed at any time, and chemotherapy can be started in the second trimester. Proof of this is the 72 children who have been born under these circumstances in the past 20 years at the Vall d’Hebrón University Hospital. This hospital is a pioneer in Spain thanks to its multidisciplinary program for education and specific follow-up with women who have been diagnosed with a breast tumor during pregnancy.”

Dr. Saura and Dr. Vivancos reported no relevant financial relationships.

Proof of this is the 72 children who have been born under these circumstances in the past 20 years at the Vall d’Hebrón University Hospital. This hospital is a pioneer in Spain thanks to its multidisciplinary program for education and specific follow-up with women who have been diagnosed with a breast tumor during pregnancy.”

Dr. Saura and Dr. Vivancos reported no relevant financial relationships.

SAN DIEGO – Treatment with benralizumab (Fasenra) achieved remission at 36 and 48 weeks at rates similar to those of mepolizumab (Nucala) in a head-to-head phase 3 trial of the two drugs for patients with a relapsing or refractory case of the rare vasculitis eosinophilic granulomatosis with polyangiitis (EGPA).

Benralizumab, a monoclonal antibody from AstraZeneca that binds to the alpha chain of the interleukin (IL)-5 receptor, is indicated as an add-on maintenance treatment for patients 12 years and older with severe eosinophilic asthma but is not currently approved for EGPA. Mepolizumab is a humanized monoclonal antibody targeting IL-5 and the only approved drug for EGPA.

Peter A. Merkel, MD, presented the trial, known as MANDARA, during a late-breaking poster session at the annual meeting of the American College of Rheumatology. A total of 140 patients with EGPA received either subcutaneous benralizumab 30 mg or mepolizumab 300 mg every 4 weeks for 52 weeks. The trial, which began recruitment in late 2019, was limited to patients at least 18 years of age with relapsing/refractory EGPA that required stable use of oral glucocorticoids (OGCs) and immunosuppressive therapy for at least 4 weeks prior to randomization, and the primary endpoint was the proportion of patients who achieved remission at weeks 36 and 48. Remission was defined as a Birmingham Vasculitis Activity Score (BVAS) of 0 plus an OGC dose of no more than 4 mg/day. Secondary endpoints included rates of accrued and maintained remission, OGC use, clinical benefit and complete response, blood eosinophil counts, total BVAS, and Vascular Damage Index scores. The mean age of the 140 patients was 52 years, and 60% were women.

Dr. Merkel and colleagues reported that the adjusted remission rate at both weeks 36 and 48 was 59.2% for those in the benralizumab arm and 56.5% for those in the mepolizumab arm (P = .7278). The percentage of patients who achieved a BVAS of 0 was similar between the two arms (83% in the benralizumab arm vs. 84.2% for those in the mepolizumab arm; P = .8502), as was the percentage of patients on an OGC dose of up to 4 mg/day (62.1% vs. 57.9%; P = .5942). At 48-52 weeks, 86.1% of patients in the benralizumab arm achieved up to a 50% reduction in OGC use, compared with 73.9% of those in the mepolizumab arm (P = .0611), and 41.4% of patients in the benralizumab arm achieved a 100% reduction in OGC use, compared with 25.8% of those in the mepolizumab arm (P = .0406).

In findings related to safety, the top three adverse events were COVID-19 (21.4% in the benralizumab arm vs. 27.1% in the mepolizumab arm, respectively), headache (17.1% vs. 15.7%), and arthralgia (17.1% vs. 11.4%).

“We were pleased with the findings because they met our expectations,” Dr. Merkel, chief of rheumatology and professor of medicine and epidemiology at the University of Pennsylvania, Philadelphia, said in an interview. “The hypothesis was that these two drugs would be equivalent and safe. The implication for patients is that they’ll have another treatment option for EGPA, which is an underrecognized disease with need for more effective treatments. I anticipate that the drug will be approved for use in EGPA, providing another option for treating this complicated multisystem eosinophilic-associated disease. Having more options for our biologic therapies is good.”

He characterized the retention of patients in MANDARA as “remarkable, despite the COVID-19 pandemic. Patients with rare diseases are quite dedicated to helping conduct research. They know that their disease is not common and that they could help others.”

The study was sponsored and funded by AstraZeneca. Dr. Merkel disclosed that he has received consulting fees and research support from many pharmaceutical companies, including AstraZeneca.

Worsening heart failure is accompanied by a build-up of fluid in the lungs. An AI smartphone app that picks up changes in a heart failure patient’s voice quality caused by this fluid accumulation and then alerts the physician about them – nearly 3 weeks before that ongoing decompensation would necessitate hospitalization and/or lead the physician to urgently introduce intravenous diuretics – is getting experts to sit up and take notice.

“In this incredibly prevalent waxing and waning condition, finding ways to identify worsening heart failure to prevent hospitalization and progressive disease is incredibly important,” observed American Heart Association (AHA)-appointed discussant David Ouyang, MD, assistant professor, Smidt Heart Institute, Division of Artificial Intelligence in Medicine, Cedars Sinai, Los Angeles. “Heart failure remains among the most common causes of hospitalization for older adults in the United States.

“The other standout feature is that we all use our cell phones on a daily basis,” Dr. Ouyang said at a late-breaking trial press briefing at the AHA 2023 annual meeting where results of the HearO Community Study were presented. “The ability to capture data from routine speech (patients speak five sentences into their phones every morning) is remarkable ... The HearO^® technology was able to detect a substantial proportion of worsening heart failure events, with an average per individual of only three false positives over the course of a year. And, adherence to the study protocol was 81%. That’s higher than in many other kinds of routine patient monitoring studies,” he added.
 

Accumulating fluid changes speech

Increased hydration may affect speech parameters such as pitch, volume, and dynamics through swelling of soft tissues in the vocal tract (e.g., pharynx, velum, tongue, and vocal folds). In the Israeli study, investigators enrolled 416 adults (75% were male, average age was 68 years) whose New York Heart Association (NYHA) 2-3 heart failure with either reduced or preserved ejection fraction was stable but placed them at-risk for heart failure events. The study goal was to analyze their speech data using the HearO^® system to refine and test its ability to detect impending heart failure deterioration. Patients recorded five sentences in their native language (Hebrew, Russian, Arabic, or English) into the smartphone app daily. In a training phase of the study, distinct speech measures from 263 participants were used to develop the AI algorithm. Then, the algorithm was used in the remaining 153 participants to validate the tool’s effectiveness. In its ultimate form, once a deviation from the patient’s predefined baseline is detected, the app will generate a notice and send it to the health care practitioners.

Lead study author William T. Abraham, MD, FAHA, professor of medicine, physiology, and cell biology; and a College of Medicine Distinguished Professor in the division of cardiovascular medicine at The Ohio State University in Columbus, reported that between Mar. 27, 2018, and Nov. 30, 2021, subjects in the training phase made recordings on 83% of days. They were followed for up to 44 months. The test group made recordings on 81% of days between Feb. 1, 2020, and Apr. 30, 2023, and were followed for up to 31 months. Heart failure events were defined as hospitalization or outpatient intravenous diuretic treatment for worsening heart failure.

In the training phase, the app accurately predicted 44 of 58 heart failure events (76%) and 81% of first events (n = 35) on average 24 days before hospitalization or need for intravenous fluids. In the validation phase, the app was 71% accurate in detecting 10 of 14 heart failure events and 77% of first events (n = 10) on average 26 days in advance of events. In both periods, the app generated about 3 unnecessary alerts per patient year.

Dr. Abraham concluded, “This technology has the potential to improve patient outcomes, keeping patients well and out of the hospital, through the implementation of proactive, outpatient care in response to voice changes.”

The HearO^® technology is being evaluated in an ongoing pivotal trial in the United State4s, Dr. Abraham said. The study is limited, he added, by the small number of patients and heart failure events, particularly in the test group.

“We continue to struggle with the burden of heart failure morbidity,” observed AHA press briefing moderator (and past AHA president) Clyde Yancy, MD, Magerstadt Professor at Northwestern University, Chicago. “So any tool that we can utilize and further refine that helps us address the need for hospitalization becomes very important. The idea that speech evaluation might give us sufficient early warning to forestall any admissions – and consider the cost savings attributable to that – is a very credible goal that we should continue to follow.” He pointed out that the technology enables assessments in the home environment for older patients who are less mobile.

In response to a press briefing question about the potential for physicians to be trained to hear early subtle voice changes on their own, Dr. Abraham stated, “I guess that is unknown, but the important difference is the system’s ability to take data in every day from patients and then process it automatically with AI.”

Joining in, Dr. Yancy said, “You know, this is interesting because even if you saw a patient once a month, which is an incredible frequency for any practice, there’s still 353 days that you haven’t seen the patient.” He noted that the AHA had just announced a multi-million dollar program to more deeply understand telemanagement. “So I think this is here to stay,” Dr. Yancy said.

Dr. Ouyang posed a further question. “Like with most AI recognition tools, we can now identify individuals at risk. How do we get from that step of identifying those at risk to improving their outcomes? This has been a critical question about heart failure, remote management, and remote monitoring, and I think it is a critical question for many of our AI tools.”

Dr. Abraham disclosed that he has received personal fees from Cordio Medical. Dr. Ouyang said that he had no disclosures relevant to this presentation.

PHILADELPHIA – The first in-human study of a gene therapy designed to reduce low-density lipoprotein cholesterol has shown a signal that the treatment works in a small group of patients with heterozygous familial hypercholesterolemia (HeFH).

While one of four patients in the highest-dose groups had a myocardial infarction the day after getting the treatment, investigators have enough confidence to go forward with the next phase of study.

“The HEART-1trial demonstrated the first human proof of concept for in vivo DNA-based editing,” said Andrew Bellinger, MD, PhD, chief scientific officer of Verve Therapeutics, the company developing the treatment. “We saw dose-dependent–based reductions in LDL and the PCSK9 protein.”

The HEART-1 study was a phase 1b trial of VERVE-101, a CRISPR-based gene editing mechanism designed to inactivate the liver gene PCSK9, which contributes to raising cholesterol. “Human genetics suggest that turning off the cholesterol-raising gene PCSK9 in the liver will durably reduce LDL cholesterol,” Dr. Bellinger said in presenting the results at the annual scientific sessions of the American Heart Association.

Lipid nanoparticle

VERVE-101 is designed to be a single-course treatment to specifically treat HeFH, Dr. Bellinger said. He explained how the therapy, given by intravenous infusion, differs from adeno-associated virus vectors that have dominated gene therapy platforms.

“It’s a lipid nanoparticle encapsulating two RNA nanoparticles that are taken up by hepatocytes in the liver from the blood by the LDL receptor,” he explained. “Then the A-to-G–based editor protein and the guide mRNA protein together find the PCSK9 gene in the liver.” That single DNA-base change in one position of the PCSK9 gene is able to turn off PCSK9 production in those liver cells.

Dr. Bellinger presented interim results of the first 10 patients treated in the open-label, single ascending dose study. The patients were male and female, ages 18-75, with HeFH, established atherosclerotic cardiovascular disease and uncontrolled hypercholesterolemia despite being on maximally tolerated lipid-lowering therapy.

They received four different doses: Three patients each received 0.1, 0.3, and 0.45 mg/kg; and one patient received 0.6 mg/kg.

Reductions in blood PCSK9 levels were measured across all dosing groups at 4 weeks, but they were most pronounced in the two highest groups, Dr. Bellinger said. Two patients in the 0.45-mg/kg group had reductions of 59% and 84%. The sole patient in the 0.6-mg/kg arm had a reduction of 47%.

Regarding the 84% reduction in one individual, Dr. Bellinger said, “Roughly 85% of PCSK9 comes from the liver. These data suggest that we have successfully made a single base pair change in both copies of the PCSK9 gene in nearly every hepatocyte in the liver of this individual.”

Those benefits carried over to LDL cholesterol measures, with the highest-dose patients registering 39%, 48% and 55% reductions.
 

Safety outcomes

Two patients had serious cardiovascular (CV) events. One in the 0.3-mg/kg arm died from cardiac arrest 5 weeks after receiving the infusion. A patient in the 0.45-mg/kg arm had a myocardial infarction a day after getting the infusion and then nonsustained ventricular tachycardia (NSVT) 4 weeks later. Dr. Bellinger said an independent review panel determined that the CV events were in line with outcomes for high-risk patients and weren’t directly related to treatment.

He added, “Increased liver transaminases were seen in patients treated in the higher-dose cohorts. It’s transient, asymptomatic, and it resolved quickly.”

The next step involves pursuing only the 0.45- and 0.6-mg/kg doses in the next dose-escalation phase and enrolling an expansion cohort in 2024, Dr. Bellinger said, with a plan to initiate a randomized, placebo-controlled phase 2 trial in 2025.
 

First, do no harm

Karol Watson, MD, PhD, a women’s cardiovascular disease specialist at UCLA, said the promise of gene therapy was “revolutionary,” but that proving safety was critical going forward.

“You’re changing the genome forever,” she said. “Safety is going to be of the utmost importance especially because there are currently safe and efficacious strategies available for lipid lowering. This is a strategy that could be revolutionary, but we have to make sure that it’s safe.”

She pointed to a multinational study from earlier this year that warned about pathogenic consequences from CRISPR-based gene editing. “There are concerns about gene editing,” Dr. Watson said. “This was a whole-genome analysis showing atypical nonhomologous on-target effects of genome editing. Of course this is a very different strategy from what we heard today, but, again, we have to know that this is safe.”

Despite the small sample size from the two highest-dose groups in the study, Dr. Watson said the investigators have reason for going forward. “I think the preclinical data supports moving forward, but the next studies will have to be scrutinized carefully,” she said. “This is a preventive therapy; the first tenet is to do no harm.”

PHILADELPHIA – The first in-human study of a gene therapy designed to reduce low-density lipoprotein cholesterol has shown a signal that the treatment works in a small group of patients with heterozygous familial hypercholesterolemia (HeFH).

While one of four patients in the highest-dose groups had a myocardial infarction the day after getting the treatment, investigators have enough confidence to go forward with the next phase of study.

“The HEART-1trial demonstrated the first human proof of concept for in vivo DNA-based editing,” said Andrew Bellinger, MD, PhD, chief scientific officer of Verve Therapeutics, the company developing the treatment. “We saw dose-dependent–based reductions in LDL and the PCSK9 protein.”

The HEART-1 study was a phase 1b trial of VERVE-101, a CRISPR-based gene editing mechanism designed to inactivate the liver gene PCSK9, which contributes to raising cholesterol. “Human genetics suggest that turning off the cholesterol-raising gene PCSK9 in the liver will durably reduce LDL cholesterol,” Dr. Bellinger said in presenting the results at the annual scientific sessions of the American Heart Association.

Lipid nanoparticle

VERVE-101 is designed to be a single-course treatment to specifically treat HeFH, Dr. Bellinger said. He explained how the therapy, given by intravenous infusion, differs from adeno-associated virus vectors that have dominated gene therapy platforms.

“It’s a lipid nanoparticle encapsulating two RNA nanoparticles that are taken up by hepatocytes in the liver from the blood by the LDL receptor,” he explained. “Then the A-to-G–based editor protein and the guide mRNA protein together find the PCSK9 gene in the liver.” That single DNA-base change in one position of the PCSK9 gene is able to turn off PCSK9 production in those liver cells.

Dr. Bellinger presented interim results of the first 10 patients treated in the open-label, single ascending dose study. The patients were male and female, ages 18-75, with HeFH, established atherosclerotic cardiovascular disease and uncontrolled hypercholesterolemia despite being on maximally tolerated lipid-lowering therapy.

They received four different doses: Three patients each received 0.1, 0.3, and 0.45 mg/kg; and one patient received 0.6 mg/kg.

Reductions in blood PCSK9 levels were measured across all dosing groups at 4 weeks, but they were most pronounced in the two highest groups, Dr. Bellinger said. Two patients in the 0.45-mg/kg group had reductions of 59% and 84%. The sole patient in the 0.6-mg/kg arm had a reduction of 47%.

Regarding the 84% reduction in one individual, Dr. Bellinger said, “Roughly 85% of PCSK9 comes from the liver. These data suggest that we have successfully made a single base pair change in both copies of the PCSK9 gene in nearly every hepatocyte in the liver of this individual.”

Those benefits carried over to LDL cholesterol measures, with the highest-dose patients registering 39%, 48% and 55% reductions.
 

Safety outcomes

Two patients had serious cardiovascular (CV) events. One in the 0.3-mg/kg arm died from cardiac arrest 5 weeks after receiving the infusion. A patient in the 0.45-mg/kg arm had a myocardial infarction a day after getting the infusion and then nonsustained ventricular tachycardia (NSVT) 4 weeks later. Dr. Bellinger said an independent review panel determined that the CV events were in line with outcomes for high-risk patients and weren’t directly related to treatment.

SAN DIEGO – Researchers say they’ve developed a novel blood-based assay that can differentiate patients with seropositive or seronegative rheumatoid arthritis from healthy people and those with other inflammatory diseases or osteoarthritis.

While cautioning that the results need to be confirmed, University of Oxford (England) rheumatologist Peter Taylor, PhD, MA, told an audience at the annual meeting of the American College of Rheumatology that the test has an overall mean sensitivity of 90.8% (standard deviation, 0.94%; 95% confidence interval, 83.2%-95.4%) and mean specificity of 96.1% (SD, 0.64%; 95% CI, 92.7%-97.9%). The mean area under the curve (AUC) is 0.991 (SD, 0.001; 95% CI, 97.2%-99.6%).

The patient was given a diagnosis of sialadenosis (also known as sialosis), a noninflammatory, non-neoplastic enlargement of the parotid glands. It can often manifest as fatty degeneration of the parotid glands, which may be associated with underlying conditions such as hypertriglyceridemia, diabetes, and metabolic syndrome.^1-3

Ultrasonography and a subsequent computed tomography with contrast demonstrated fatty hypertrophy of the parotid glands without any concerning parotid mass or enlarged cervical lymph nodes. No abnormalities of the ductal system (eg, stricture or obstruction with stone) were noted, so sialography and sialendoscopy were not indicated.

Evaluation for inflammatory, autoimmune, and granulomatous diseases was negative, including negative anti-Ro/SSA and anti-La/SSB antibodies and negative HIV screen. However, our patient had an elevated serum triglyceride level of 589 mg/dL (reference range, < 150 mg/dL), while serum total cholesterol was within the reference range (< 200 mg/dL). (Interestingly, his triglycerides were normal a year earlier.) The patient’s A1c level was normal.

The differential diagnosis for this patient included Sjögren syndrome, abscess, viral infection (eg, mumps, HIV sialopathy), Kimura disease, sarcoidosis, masseter hypertrophy, and tumors of the parotid gland (eg, Warthin tumor and pleomorphic adenoma). Drug-induced sialadenitis was another possibility, as several drugs may be associated with salivary gland enlargement.⁴ However, no association was found for our patient.

Primary management is focused on treating the underlying disorder. The application of heat, massage, and sialagogues (eg, pilocarpine 5 mg orally tid) can be used to stimulate salivation, which may help reduce the swelling. Bilateral parotid gland swelling in patients with increased triglyceride levels often resolves after treatment of hypertriglyceridemia.^3,5 Less common modalities include botulinum neurotoxin injection, tympanic neurectomy, and parotidectomy.⁶

The treatment plan for this patient included aggressive dietary modification and increasing his current dosage of atorvastatin from 20 mg to 80 mg at bedtime. Increasing the dosage of statin was preferred over adding another agent (such as fibrates) to decrease the risk of myopathy. Fine-needle aspiration biopsy may be considered if the swelling does not resolve after correction of lipid abnormalities, which can take between 6 months and 3 years.³

SAN DIEGO – A split dose of methotrexate (MTX) given orally once per week showed significantly higher efficacy in patients with rheumatoid arthritis at 16 weeks, compared with a single MTX dose weekly, according to new research. By 24 weeks, efficacy measures were similar for both groups.

However, fewer patients in the split-dose group needed additional disease-modifying antirheumatic drugs (DMARDs) to control disease activity.

MTX is a highly utilized, inexpensive drug for RA, but only about 30% of patients can achieve low disease activity or remission on MTX monotherapy, said Varun Dhir, MD, MBBS, of the Postgraduate Institute of Medical Education and Research, Chandigarh, India. He co-authored and presented the research at the annual meeting of the American College of Rheumatology.

Part of the problem is that “oral methotrexate absorption from the gut reduces as the doses go up,” Dr. Dhir noted, because the transport mechanism gets saturated. MTX delivered subcutaneously is one way to improve efficacy, but patients can be needle-averse, and in some countries, like India, pre-filled syringes are not available, he said.

There is pharmacokinetic data dating back 20 years that suggest split-dose MTX could be more efficacious. “However, there are no randomized controlled trials to date, and the guidelines therefore are silent on this approach,” Dr. Dhir said.

To address this question, Dr. Dhir and colleagues recruited patients with RA from six centers across India. Patients were aged 18-60 years, seropositive (rheumatoid factor or anti-citrullinated protein antibodies), and had a disease duration of 5 years or fewer. Patients had active disease, defined as at least four tender joints and at least two swollen joints, and were not taking any DMARDs except for hydroxychloroquine and/or low-dose prednisolone.

A total of 253 patients were randomly assigned to a single 25-mg dose or a split-dose of MTX once weekly (10 mg in the morning and 15 mg in the evening on the same day). The primary outcome was a European Alliance of Associations for Rheumatology (EULAR) good response at 24 weeks. At the 16-week mark, if patients had not achieved low disease activity based on a 28-joint Disease Activity Score (DAS28) greater than 3.2, a blinded assessor could add either leflunomide or sulfasalazine to the continued MTX therapy.

At baseline, there was no difference between the groups’ DAS28, but after 16 weeks, DAS28 was significantly lower in the split-dose group, compared with the single-dose group (4.4 vs. 5.1; P < .001), and a higher percentage of patients in the split-dose group had a EULAR good response.

About three-quarters (76.6%) of patients in the split-dose group experienced an improvement of at least 20% in ACR response criteria (ACR20), compared with 52% in the single-dose group. The split-dose group also had higher proportion of patients achieving ACR50 and ACR70.

About one-third of the split-dose group (35%) added an additional DMARD at 16 weeks, compared with 54.5% of the single-dose group (P = .005).

After 24 weeks, DAS28 scores remained lower in the split-dose group (4.1 vs. 4.5; P = .03), but there were no other differences in treatment responses. Health Assessment Questionnaire scores were the same between both groups at 16 and 24 weeks.

The primary outcome was not met, although Dr. Dhir noted a flaw in the study design that could have affected the results. By allowing patients to add additional DMARDs at 16 weeks, “there were two factors which were affecting the primary outcome” at 24 weeks, he told this news organization. “I feel there was a robust result at least at 16 weeks.”

While there were no major adverse events, the split-dose group had higher rates of transaminitis (elevated liver enzymes) during the study, and low white blood cell count was higher in the single-dose group at 24 weeks. There was no difference in MTX intolerance between the two groups.

“It looks like [the split-dose group] gets out of the block faster. It’s a faster effect,” although the other group did catch up, Janet Pope, MD, MPH, of Western University, London, Ont., said in an interview. She was not involved with the research. Two positive results were the earlier ACR responses in the split-dose group as well as fewer patients in that same group needing to add another DMARD to therapy.

“In my opinion, if it’s equal cost, why not try it and see?” she said.

In a separate presentation referring to the abstract, Joan Bathon, MD, director of rheumatology at Columbia University, New York City, noted that these results align with ACR 2021 recommendations. Dr. Bathon was not involved with this study but was on the writing committee establishing those 2021 guidelines.

“The recommendation – with low certainty of evidence – was that for patients who are intolerant to MTX, that split-dose of oral MTX is worth trying before you switch to a different DMARD,” she said. “I think these data support that concept.”

Dr. Dhir and Dr. Bathon had no relevant financial relationships. Dr. Pope disclosed financial relationships with AbbVie/Abbott, Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Fresenius Kabi, GlaxoSmithKline, Janssen, Mallinckrodt, Novartis, Organon, Pfizer, Sandoz, and Viatris.

MTX is a highly utilized, inexpensive drug for RA, but only about 30% of patients can achieve low disease activity or remission on MTX monotherapy, said Varun Dhir, MD, MBBS, of the Postgraduate Institute of Medical Education and Research, Chandigarh, India. He co-authored and presented the research at the annual meeting of the American College of Rheumatology.

Part of the problem is that “oral methotrexate absorption from the gut reduces as the doses go up,” Dr. Dhir noted, because the transport mechanism gets saturated. MTX delivered subcutaneously is one way to improve efficacy, but patients can be needle-averse, and in some countries, like India, pre-filled syringes are not available, he said.

There is pharmacokinetic data dating back 20 years that suggest split-dose MTX could be more efficacious. “However, there are no randomized controlled trials to date, and the guidelines therefore are silent on this approach,” Dr. Dhir said.

To address this question, Dr. Dhir and colleagues recruited patients with RA from six centers across India. Patients were aged 18-60 years, seropositive (rheumatoid factor or anti-citrullinated protein antibodies), and had a disease duration of 5 years or fewer. Patients had active disease, defined as at least four tender joints and at least two swollen joints, and were not taking any DMARDs except for hydroxychloroquine and/or low-dose prednisolone.

A total of 253 patients were randomly assigned to a single 25-mg dose or a split-dose of MTX once weekly (10 mg in the morning and 15 mg in the evening on the same day). The primary outcome was a European Alliance of Associations for Rheumatology (EULAR) good response at 24 weeks. At the 16-week mark, if patients had not achieved low disease activity based on a 28-joint Disease Activity Score (DAS28) greater than 3.2, a blinded assessor could add either leflunomide or sulfasalazine to the continued MTX therapy.

At baseline, there was no difference between the groups’ DAS28, but after 16 weeks, DAS28 was significantly lower in the split-dose group, compared with the single-dose group (4.4 vs. 5.1; P < .001), and a higher percentage of patients in the split-dose group had a EULAR good response.

About three-quarters (76.6%) of patients in the split-dose group experienced an improvement of at least 20% in ACR response criteria (ACR20), compared with 52% in the single-dose group. The split-dose group also had higher proportion of patients achieving ACR50 and ACR70.

About one-third of the split-dose group (35%) added an additional DMARD at 16 weeks, compared with 54.5% of the single-dose group (P = .005).

After 24 weeks, DAS28 scores remained lower in the split-dose group (4.1 vs. 4.5; P = .03), but there were no other differences in treatment responses. Health Assessment Questionnaire scores were the same between both groups at 16 and 24 weeks.

The primary outcome was not met, although Dr. Dhir noted a flaw in the study design that could have affected the results. By allowing patients to add additional DMARDs at 16 weeks, “there were two factors which were affecting the primary outcome” at 24 weeks, he told this news organization. “I feel there was a robust result at least at 16 weeks.”

While there were no major adverse events, the split-dose group had higher rates of transaminitis (elevated liver enzymes) during the study, and low white blood cell count was higher in the single-dose group at 24 weeks. There was no difference in MTX intolerance between the two groups.

“It looks like [the split-dose group] gets out of the block faster. It’s a faster effect,” although the other group did catch up, Janet Pope, MD, MPH, of Western University, London, Ont., said in an interview. She was not involved with the research. Two positive results were the earlier ACR responses in the split-dose group as well as fewer patients in that same group needing to add another DMARD to therapy.

“In my opinion, if it’s equal cost, why not try it and see?” she said.

In a separate presentation referring to the abstract, Joan Bathon, MD, director of rheumatology at Columbia University, New York City, noted that these results align with ACR 2021 recommendations. Dr. Bathon was not involved with this study but was on the writing committee establishing those 2021 guidelines.

“The recommendation – with low certainty of evidence – was that for patients who are intolerant to MTX, that split-dose of oral MTX is worth trying before you switch to a different DMARD,” she said. “I think these data support that concept.”

Dr. Dhir and Dr. Bathon had no relevant financial relationships. Dr. Pope disclosed financial relationships with AbbVie/Abbott, Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Fresenius Kabi, GlaxoSmithKline, Janssen, Mallinckrodt, Novartis, Organon, Pfizer, Sandoz, and Viatris.
