Ofatumumab MS Study Supports Early Start Over Switch
COPENHAGEN — according to extension data out to 6 years.
By the most recent analysis of a phase 3 extension study, there were “fewer disability worsening events and greater likelihood of being progression free among those started on ofatumumab than those started on teriflunomide and switched,” reported Amit Bar-Or, MD, director of the Center of Neuroinflammation and Neurotherapeutics, University of Pennsylvania, Philadelphia.
Stated differently, if ofatumumab is delayed, it never fully compensates for the advantage of better early MS control in treatment-naïve patients, according to Dr. Bar-Or, who presented these data at the 2024 ECTRIMS annual meeting.
Anti-CD20 Disability Protection Already Seen in Pivotal Trial
In two phase 3 trials called ASCLEPIOS I and II that were published together several years ago in The New England Journal of Medicine, the anti-CD20 monoclonal antibody ofatumumab reduced the annualized relapse rate (ARR) by half (0.11 vs. 0.22). While ARR was the primary endpoint, ofatumumab was also associated with a 34% reduction (P = .002) in risk of confirmed disability worsening at 3 months (3mCDW) at a medium follow-up of 1.6 years.
After the completion of ASCLEPIOS I and II, the majority of both arms of the study were enrolled in the ALITHIOS extension study. Patients in ofatumumab arm have remained on their initially assigned drug. Patients in the teriflunomide group were switched. Characterized as the delayed ofatumumab group, they have been receiving the same 20-mg, once-monthly subcutaneous (SQ) dose of ofatumumab as those initially assigned to this drug. ALITHIOS will continue to follow both groups until 2028.
Patients have now been followed for up to 6 years. In the latest results presented at ECTRIMS, data were available for 690 patients on continuous treatment and 677 switch patients. Baseline characteristics of the two groups were similar. About half of each group were treatment naive when enrolled in the ASCLEPIOS trials.
Whether compared for 6-month confirmed disability worsening (6mCDW), 6-month progression independent of relapse activity (6mPIRA) or 6-month relapse-associated worsening (6mRAW), disease progression was consistently worse for those with delayed ofatumumab. The differences were most pronounced in those who were treatment naive when started on therapy.
Anti-CD20 MAB sustains Disability Protection for up to Years
For those who were treatment naive, the rates of 6mCDW at the most recent follow-up were 16.61% vs 23.74% (P = .033) for continuous and delayed ofatumumab, respectively. For the entire study, these rates were 21.09% versus 24.77%, respectively, which represented a strong trend (P = .063).
The relative rates for 6mPIRA (11.12% vs 16.75%) and 6mRAW (4.26% vs 4.82%) in treatment-naive patients also favored continuous over delayed ofatumumab, and the numerical advantage was also seen with up to 6 years of follow-up in the overall study population for 6mPIRA (15.45% vs 16.56%) and 6mRAW (5.24% vs 5.81%).
Translating these into freedom from disability, Dr. Bar-Or reported that more than 80% (83.4%) of patients on continuous ofatumumab were progression free for up to 6 years, a figure that exceeded the 76.3% free of progression in the delayed ofatumumab group.
On the basis of 6mPIRA, that absence of disability progression neared 90% (88.9%) on continuous ofatumumab relative to 83.3% for delayed ofatumumab.
An advantage for a reduction in disability accumulation for ofatumumab relative to teriflunomide was established at the end of the ASCLEPIOS I and II trial, but the latest follow-up shows that it is “sustained out to 6 years.” The advantage is achieved with no greater cost in adverse events during the early treatment period, according to Dr. Bar-Or, who noted that ofatumumab and teriflunomide were similarly well tolerated in ASCLEPIOS I and II.
No New Gd T1 Lesions Observed Over 12 Months
Although other anti-CD20 monoclonal antibodies have also been shown to be highly effective and often more effective than immunomodulators in the first- and second-line treatment of relapsing remitting MS (RRMS), another set of data presented at ECTRIMS 2024 looked specifically at transitioning from intravenous (IV) anti-CD20 drugs to SQ ofatumumab.
In this study, called OLIKOS, 102 RRMS patients who had received either IV ocrelizumab or IV rituximab were followed after transitioning to ofatumumab administered SQ with an autoinjector pen. The primary endpoint was the proportion of patients with no change or a reduction gadolinium-enhancing (Gd) T1 lesions over 12 months of follow-up.
“At month 12, 84 of 84 evaluable patients with evaluable MRI assessments met the primary endpoint,” reported the principal investigator Le Hua, MD, director of the Multiple Sclerosis Program, Cleveland Clinic in Ohio.
At 12 months, there were also no new or enlarging T2 lesions in 98% of patients receiving SQ ofatumumab following the transition from one of the other anti-CD20 IV drugs, but Dr. Hua characterized this as an exploratory endpoint.
The safety and tolerability data during the OLIKOS study was also reassuring with no new or unexpected safety signals for SQ ofatumumab, which has been well tolerated in the phase 3 development program. IgM and IgG levels remained stable over the course of follow-up.
High-efficacy anti-CD20 drugs were once reserved for RRMS patients with highly active disease, but long-term data, such as those generated by the ALITHIOS extension study, suggest greater efficacy with acceptable safety of these agents relative to conventional first-line RRMS therapies. Based on ALITHIOS data, Dr. Bar-Or suggested that early use of the most effective therapy appears to lead to better long-term protection from increased cumulative disability.
Dr. Bar-Or reported financial relationships with Accure, Atara, Biogen, Bristol-Myers Squibb, Celgene, GlaxoSmithKline, Gossamer, Janssen/Actelion, Medimmune, Merck/EMD Serono, Novartis, Roche/Genentech, and Sanofi-Genzyme. Dr. Hua reported financial relationships with Alexion, EMD Serono, Genentech, Horizon, Novartis, and TG Therapeutics.

What We Know About Salmon Sperm in Dermatology
It may not have an aesthetic-sounding appeal to most people, but salmon sperm is indeed one of the novel ingredients featured in products for human skin. These products also reportedly enhance and promote skin regeneration.1 This column will focus on the innovative approach to skin care involving purified polynucleotides derived from salmon sperm.
The Properties and Activities of PDRNs, PNs
PDRNs contain DNA fragments primarily derived from Pacific or chum salmon (Oncorhynchus keta), and salmon trout (Oncorhynchus mykiss) sperm cells.2 Through preclinical and clinical trials, PDRN has demonstrated a wide range of salutary functions, including antiallodynic, antiapoptotic, anti-inflammatory, antimelanogenetic, antiosteonecrotic, antiosteoporotic, antiulcerative, bone-regenerative, tissue damage–preventive, and wound-healing activities through adenosine A2A receptor and salvage pathways activation. Indeed, PDRNs have been shown in vitro to spur the proliferation of preadipocytes and, in vivo, to be effective in treating wounds and ulcers.3,4 In particular, atrophic, hypertrophic, surgical, and various acne scars have been treated with such injections.2,5,6 PDRN is thought to affect cutaneous health more directly by facilitating angiogenesis, cellular functions, especially fibroblast stimulation, collagen production, soft-tissue regeneration, and skin revitalization. Further, it has been used successfully to treat hyperpigmentation.7
PNs, derived from the same fish species as PDRNs, have been used effectively to ameliorate skin elasticity, hydration, pore size, thickness, wrinkles, as well as pigmentation and, specifically, in treating periorbital rhytides and postsurgical scars.5,6,8 Beyond skin rejuvenation, PNs have been recognized for effectiveness in treating stretch marks and achieving vulvovaginal revitalization; guidelines for its use have been established and implemented in recent years.6,9,10 In South Korea, PNs have become a popular treatment for facial erythema even though preclinical and clinical data are sparse.11 Nevertheless, the use of these novel substances is thought to foster tissue regeneration and a more natural rejuvenation than achieved through more traditional fillers.6
Skin Rejuvenation
Park and colleagues conducted a small study with five patients in 2016 in which long-chain polynucleotide filler was used for skin rejuvenation. Over a 2-week period, five Korean women received four injections of the filler (0.05 mL) on one side of the face. No adverse side effects were reported. In the patients in their 30s, pore and skin thickness significantly improved with treatment. For patients in their 40s, observable improvements were noted in melanin, sagging, skin tone, and wrinkles. Despite the small study size, the investigators concluded that this intradermal injection material is a safe and effective product for skin rejuvenation therapy.1 The product is also available in Europe and reportedly spurs the regeneration of damaged tissues and yields a more natural appearance.1
A Hybrid HA-PN Filler
Given that the most common filling agent, hyaluronic acid (HA), is associated with multiple side effects, JH Kim and colleagues set out in 2020 to compare HA with a new HA-PN dermal filler that has displayed notable biocompatibility and promoted tissue regeneration. The investigators observed that the combination filler provoked greater cell migration in a wound healing assay and was more effective in promoting collagen production in human and mouse fibroblasts. To their knowledge, this was the first study showing the efficacy, safety, and durability of a hybrid HA-PN filler. They concluded that fillers containing both HA and PN were more effective than HA alone in suppressing cutaneous aging and may represent the next step in the evolution of dermal filling agents.12
Most Recent Findings
In August 2023, MJ Kim and colleagues became the first to report on the successful use of PNs derived from fish sperm as a volumizing treatment for fat atrophy in vivo (in the temple in one case, and the cheek in the other). Injections were made into the subcutaneous layer to treat iatrogenic volume loss resulting from lipolysis injections. In one case, a depression in the left temple of a 53-year-old female lipolysis patient was treated with a series of 1 cc PN injections in a 20 mg/mL concentration. At 1 month after the final series of injections (four treatments), significant clinical improvement was observed, with the result (barely visible depression) maintained at 11 months and 21 months after the last treatment. The second patient, a 34-year-old female, presented with two depressed areas on the left cheek 2 months after steroid injections for two acne lesions. A series of PN filler injections also with a concentration of 20 mg/mL was administered (four treatments) at 1-month intervals. Significant improvement was seen 2 months after the last treatment, with maintenance of complete healing noted at 5 months and 12 months after the final treatment. No adverse effects were reported in either case. The investigators concluded that long-chain PN fillers appear to be effective in treating depressions in the skin, but more data, particularly from controlled studies, is necessary to determine the safety and efficacy as a lone therapeutic approach for soft-tissue depression.6
A month later, Lee and colleagues reported on the results of their survey of clinicians in South Korea who use PNs in clinical practice. The goal was to understand current practices and perceptions of effectiveness in treating facial erythema. Of the 557 physicians who participated, 84.4% used PNs for facial erythema provoked by inflammatory facial dermatosis, 66.4% for facial erythema induced by repeated laser/microneedle radiofrequency, and 47.4% for facial erythema caused by steroid overuse. In these same classifications, 88.1%, 90%, and 83.7%, respectively, found PNs to be “highly effective” or “effective.” Survey respondents also characterized PNs as imparting wound healing/regeneration (95.8%), skin barrier protection (92.2%), hydration (90.5%), vascular stabilization (81.0%), and anti-inflammatory activity (79.5%).11
Conclusion
The use of salmon sperm cells is an example of the recent trend toward a cellular approach in which cutaneous components are activated with the intention of stimulating tissue regeneration. It is commonly used in Brazil and my Brazilian patients seem to know all about it. This innovative outlook is intriguing as are a spate of recently reported results. Nevertheless, much more evidence is required to ascertain safety and effectiveness in large sample sizes and, ideally, to establish maintenance of corrections over longer periods whether these ingredients are used in filling agents or topical formulations.

It may not have an aesthetic-sounding appeal to most people, but salmon sperm is indeed one of the novel ingredients featured in products for human skin. These products also reportedly enhance and promote skin regeneration.1 This column will focus on the innovative approach to skin care involving purified polynucleotides derived from salmon sperm.
The Properties and Activities of PDRNs, PNs
PDRNs contain DNA fragments primarily derived from Pacific or chum salmon (Oncorhynchus keta), and salmon trout (Oncorhynchus mykiss) sperm cells.2 Through preclinical and clinical trials, PDRN has demonstrated a wide range of salutary functions, including antiallodynic, antiapoptotic, anti-inflammatory, antimelanogenetic, antiosteonecrotic, antiosteoporotic, antiulcerative, bone-regenerative, tissue damage–preventive, and wound-healing activities through adenosine A2A receptor and salvage pathways activation. Indeed, PDRNs have been shown in vitro to spur the proliferation of preadipocytes and, in vivo, to be effective in treating wounds and ulcers.3,4 In particular, atrophic, hypertrophic, surgical, and various acne scars have been treated with such injections.2,5,6 PDRN is thought to affect cutaneous health more directly by facilitating angiogenesis, cellular functions, especially fibroblast stimulation, collagen production, soft-tissue regeneration, and skin revitalization. Further, it has been used successfully to treat hyperpigmentation.7
PNs, derived from the same fish species as PDRNs, have been used effectively to ameliorate skin elasticity, hydration, pore size, thickness, wrinkles, as well as pigmentation and, specifically, in treating periorbital rhytides and postsurgical scars.5,6,8 Beyond skin rejuvenation, PNs have been recognized for effectiveness in treating stretch marks and achieving vulvovaginal revitalization; guidelines for its use have been established and implemented in recent years.6,9,10 In South Korea, PNs have become a popular treatment for facial erythema even though preclinical and clinical data are sparse.11 Nevertheless, the use of these novel substances is thought to foster tissue regeneration and a more natural rejuvenation than achieved through more traditional fillers.6
Skin Rejuvenation
Park and colleagues conducted a small study with five patients in 2016 in which long-chain polynucleotide filler was used for skin rejuvenation. Over a 2-week period, five Korean women received four injections of the filler (0.05 mL) on one side of the face. No adverse side effects were reported. In the patients in their 30s, pore and skin thickness significantly improved with treatment. For patients in their 40s, observable improvements were noted in melanin, sagging, skin tone, and wrinkles. Despite the small study size, the investigators concluded that this intradermal injection material is a safe and effective product for skin rejuvenation therapy.1 The product is also available in Europe and reportedly spurs the regeneration of damaged tissues and yields a more natural appearance.1
A Hybrid HA-PN Filler
Given that the most common filling agent, hyaluronic acid (HA), is associated with multiple side effects, JH Kim and colleagues set out in 2020 to compare HA with a new HA-PN dermal filler that has displayed notable biocompatibility and promoted tissue regeneration. The investigators observed that the combination filler provoked greater cell migration in a wound healing assay and was more effective in promoting collagen production in human and mouse fibroblasts. To their knowledge, this was the first study showing the efficacy, safety, and durability of a hybrid HA-PN filler. They concluded that fillers containing both HA and PN were more effective than HA alone in suppressing cutaneous aging and may represent the next step in the evolution of dermal filling agents.12
Most Recent Findings
In August 2023, MJ Kim and colleagues became the first to report on the successful use of PNs derived from fish sperm as a volumizing treatment for fat atrophy in vivo (in the temple in one case, and the cheek in the other). Injections were made into the subcutaneous layer to treat iatrogenic volume loss resulting from lipolysis injections. In one case, a depression in the left temple of a 53-year-old female lipolysis patient was treated with a series of 1 cc PN injections in a 20 mg/mL concentration. At 1 month after the final series of injections (four treatments), significant clinical improvement was observed, with the result (barely visible depression) maintained at 11 months and 21 months after the last treatment. The second patient, a 34-year-old female, presented with two depressed areas on the left cheek 2 months after steroid injections for two acne lesions. A series of PN filler injections also with a concentration of 20 mg/mL was administered (four treatments) at 1-month intervals. Significant improvement was seen 2 months after the last treatment, with maintenance of complete healing noted at 5 months and 12 months after the final treatment. No adverse effects were reported in either case. The investigators concluded that long-chain PN fillers appear to be effective in treating depressions in the skin, but more data, particularly from controlled studies, is necessary to determine the safety and efficacy as a lone therapeutic approach for soft-tissue depression.6
A month later, Lee and colleagues reported on the results of their survey of clinicians in South Korea who use PNs in clinical practice. The goal was to understand current practices and perceptions of effectiveness in treating facial erythema. Of the 557 physicians who participated, 84.4% used PNs for facial erythema provoked by inflammatory facial dermatosis, 66.4% for facial erythema induced by repeated laser/microneedle radiofrequency, and 47.4% for facial erythema caused by steroid overuse. In these same classifications, 88.1%, 90%, and 83.7%, respectively, found PNs to be “highly effective” or “effective.” Survey respondents also characterized PNs as imparting wound healing/regeneration (95.8%), skin barrier protection (92.2%), hydration (90.5%), vascular stabilization (81.0%), and anti-inflammatory activity (79.5%).11
Conclusion
The use of salmon sperm cells is an example of the recent trend toward a cellular approach in which cutaneous components are activated with the intention of stimulating tissue regeneration. It is commonly used in Brazil and my Brazilian patients seem to know all about it. This innovative outlook is intriguing as are a spate of recently reported results. Nevertheless, much more evidence is required to ascertain safety and effectiveness in large sample sizes and, ideally, to establish maintenance of corrections over longer periods whether these ingredients are used in filling agents or topical formulations.

FDA’s Stricter Regulation of Lab-Developed Tests Faces Lawsuits and Lingering Concerns
The Food and Drug Administration (FDA) plans to scrutinize the safety and efficacy of lab-developed tests — those designed, manufactured, and used in a single laboratory — far more thoroughly in the future.
Under a rule finalized in April, the FDA will treat facilities that develop and use lab tests as manufacturers and regulate tests as medical devices. That means that most lab tests will need an FDA review before going on sale.
The FDA will also impose new quality standards, requiring test manufacturers to report adverse events and create a registry of lab tests under the new rule, which will be phased in over 4 years.
FDA officials have been concerned for years about the reliability of commercial lab tests, which have ballooned into a multibillion-dollar industry.
Consumer groups have long urged the FDA to regulate lab tests more strictly, arguing that the lack of scrutiny allows doctors and patients to be exploited by bad actors such as Theranos, which falsely claimed that its tests could diagnose multiple diseases with a single drop of blood.
“When it comes to some of these tests that doctors are recommending for patients, many doctors are just crossing their fingers and relying on the representation of the company because nobody is checking” to verify a manufacturer’s claims, said Joshua Sharfstein, MD, vice dean for public health practice and community engagement at the Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland.
Nearly 12,000 Labs Making Medical Tests
Although the FDA estimates there are nearly 12,000 labs manufacturing medical tests, agency officials said they don’t know how many tests are being marketed. The FDA already requires that home test kits marketed directly to consumers, such as those used to detect COVID-19, get clearance from the agency before being sold.
“There’s plenty of time for industry to get its act together to develop the data that it might need to make a premarket application,” said Peter Lurie, MD, PhD, a former associate commissioner at the FDA. In 2015, Dr. Lurie led a report outlining some of the dangers of unregulated lab tests.
For the average physician who orders lab tests, nothing is going to immediately change because of the final rule, said Dr. Lurie, now president of the Center for Science in the Public Interest, a nonprofit consumer watchdog.
“Tomorrow, this will look just the same as it does today,” Dr. Lurie said. “For the next 3 years, the companies will be scurrying behind the scenes to comply with the early stages of implementation. But most of that will be invisible to the average practitioner.”
Dr. Lurie predicted the FDA will focus its scrutiny on tests that pose the greatest potential risk to patients, such as ones used to diagnose serious diseases or guide treatment for life-threatening conditions. “The least significant tests will likely get very limited, if any, scrutiny,” said Dr. Lurie, adding that the FDA will likely issue guidance about how it plans to define low- and high-risk tests. “My suspicion is that it will be probably a small minority of products that are subject to full premarket approval.”
Lab Industry Groups Push Back
But imposing new rules with the potential to affect an industry’s bottom line is no easy task.
The American Clinical Laboratory Association, which represents the lab industry, said in a statement that the FDA rule will “limit access to scores of critical tests, increase healthcare costs, and undermine innovation in new diagnostics.” Another industry group, the Association for Molecular Pathology, has warned of “significant and harmful disruption to laboratory medicine.”
The two associations have filed separate lawsuits, charging that the FDA overstepped the authority granted by Congress. In their lawsuits, groups claim that lab tests are professional services, not manufactured products. The groups noted that the Centers for Medicare & Medicaid Services (CMS) already inspects lab facilities. CMS does not assess the tests’ quality or reliability.
A recent Supreme Court decision could make those lawsuits more likely to succeed, said David Simon, JD, LLM, PhD, an assistant professor of law at the Northeastern University School of Law, Boston, Massachusetts.
In the case of Loper Bright Enterprises v. Raimondo, decided in June, justices overturned a long-standing precedent known as Chevron deference, which required courts to defer to federal agencies when interpreting ambiguous laws. That means that courts no longer have to accept the FDA’s definition of a device, Dr. Simon said.
“Because judges may have more active roles in defining agency authority, federal agencies may have correspondingly less robust roles in policymaking,” Dr. Simon wrote in an editorial coauthored with Michael J. Young, MD, MPhil, of Harvard Medical School, Boston.
The Supreme Court ruling could pressure Congress to more clearly define FDA’s ruling in regulating lab tests, Dr. Simon and Dr. Young wrote.
Members of Congress first introduced a bill to clarify the FDA’s role in regulating lab tests, called the VALID Act, in 2020. The bill stalled and, despite efforts to revive it, still hasn’t passed.
FDA officials have said they remain “open to working with Congress,” noting that any future legislation about lab-developed tests would supersede their current policy.
In an interview, Dr. Simon noted the FDA significantly narrowed the scope of the final rule in response to comments from critics who objected to an earlier version of the policy proposed in 2023. The final rule carves out several categories of tests that won’t need to apply for “premarket review.”
Notably, a “grandfather clause” will allow some lab tests already on the market to continue being sold without undergoing FDA’s premarket review process. In explaining the exemption, FDA officials said they did not want doctors and patients to lose access to tests on which they rely. But Dr. Lurie noted that because the FDA views all these tests as under its jurisdiction, the agency could opt to take a closer look “at a very old device that is causing a problem today.”
The FDA also will exempt tests approved by New York State’s Clinical Laboratory Evaluation Program, which conducts its own stringent reviews. And the FDA will continue to allow hospitals to develop tests for patients within their healthcare system without going through the FDA approval process, if no FDA-approved tests are available.
Hospital-based tests play a critical role in treating infectious diseases, said Amesh Adalja, MD, an infectious diseases specialist and senior scholar at the Johns Hopkins Center for Health Security. For example, a large research hospital treating a patient with cytomegalovirus may need to develop its own test to determine whether the infection is resistant to antiviral drugs, Dr. Adalja said.
“With novel infectious disease outbreaks, researchers are able to move quickly to make diagnostic tests months and months before commercial laboratories are able to get through regulatory processes,” Dr. Adalja said.
To help scientists respond quickly to emergencies, the FDA published special guidance for labs that develop unauthorized lab tests for disease outbreaks.
Medical groups such as the American Hospital Association and Infectious Diseases Society of America remain concerned about the burden of complying with new regulations.
“Many vital tests developed in hospitals and health systems may be subjected to unnecessary and costly paperwork,” said Stacey Hughes, executive vice president of the American Hospital Association, in a statement.
Other groups, such as the American Society of Clinical Oncology, praised the new FDA policy. In comments submitted to the FDA in 2023, the cancer group said it “emphatically supports” requiring lab tests to undergo FDA review.
“We appreciate FDA action to modernize oversight of these tests and are hopeful this rule will increase focus on the need to balance rapid diagnostic innovation with patient safety and access” Everett Vokes, MD, the group’s board chair, said in a statement released after the FDA’s final rule was published.

Doulas Support Moms-to-Be and Try to Fit Into the Obstetric Care Team
It’s well known that the United States enjoys the dubious distinction of having the worst maternal morbidity and mortality rates among industrialized nations. Maternal mortality in this country increased by 14% from 2018 to 2020, according to the Centers for Disease Control and Prevention’s National Center for Health Statistics.
But a current trend of engaging birth doulas — nonmedical guides offering continuous one-on-one physical and psychological support in the pre-, peri,- and postnatal periods — may be poised to brighten that dismal statistical landscape.
Recent research has shown that mothers matched with a doula are less likely to have a low birth weight baby, less likely to experience a birth complication, and significantly more likely to initiate breastfeeding.
Doula services — even delivered digitally — are seen to lower healthcare costs, reduce cesarean sections, decrease maternal anxiety and depression, and improve communication between healthcare providers and low-income, racially/ethnically diverse pregnant women. Doulas can be especially helpful for mothers dealing with the psychological fallout of miscarriage or stillbirth. They can guide patients in the postpartum period, when problems can arise and when some mothers are lost to medical follow-up, and provide an ongoing source of patient information for the ob.gyn.
“Research has shown that in addition to better outcomes, doula care can shorten labor time and increase patient satisfaction,” said ob.gyn. Layan Alrahmani, MD, in an interview. A maternal-fetal medicine specialist with a focus on high-risk pregnancies among low-income women at Loyola Medicine in Maywood, Illinois, Dr. Alrahmani welcomes doulas to her patients’ antenatal visits.
“Many of my patients who are looking to avoid an epidural will work with a labor doula, in order to stay home as long as possible and to have one-on-one coaching through the pain as things progress,” said Susan Rothenberg, MD, an assistant professor of obstetrics, gynecology, and reproductive science at the Icahn School of Medicine at Mount Sinai and an ob/gyn at Mount Sinai Downtown Union Square in New York City. She added, “When a woman’s partner is squeamish or potentially unavailable, a labor doula can be a great option.”
Another ob.gyn. who enthusiastically embraces doula care is L. Joy Baker, MD, who practices in LaGrange, Georgia, and is affiliated with Wellstar West Georgia Medical Center. “I love it when my patients have a doula. A doula answers a patient’s questions throughout the pregnancy and amplifies the mother’s voice in the medical system and the clinical setting,” Dr. Baker told this news organization.
“They provide important details on patients’ food, housing, and transportation status when the mothers themselves would not bring those up in a short appointment with their doctors,” she said. Dr. Baker called for more recognition of their merit, especially for first-time and high-risk moms.
Efua B. Leke, MD, MPH, an assistant professor at Baylor College of Medicine and chief of obstetrics at Ben Taub Hospital in Houston, Texas, also believes a major benefit of doulas is improved flow of information. “We know that having doulas participate in maternal care can ease communication between pregnant and parturient mothers and their clinical team,” Dr. Leke said. “This is especially important for under-resourced pregnant women for whom morbidity tends to be disparately higher.”
Doulas can also take pressure off embattled ob.gyn. clinical staff. “Our volume of patients is huge, so we have to keep appointments brief,” Dr. Baker said. “The US is currently 8000 ob.gyn.s short, and to make matters worse, we’re seeing more and more obstetrical care deserts.”
Still largely underutilized, doula care is seen by its proponents as important in light of the drastic shortage of ob.gyn.s and the shrinking presence of maternity care in many US counties.
According to a recent March of Dimes report, access to maternity care is waning, with more than 35% of US counties offering no community obstetrical care and 52% providing no maternity care in local hospitals. That translates to long distances and extended travel time for mothers seeking care.
Growth Remains Slow
Although many believe doulas could become part of the solution to the lack of access to maternity care, their acceptance seems to be slow growing. In a 2012 national survey by Declercq and associates, about 6% of mothers used a doula during childbirth, up from 3% in a 2006 national survey. Of those who were familiar with but lacking doula care, just 27% would have chosen to have this service.
“I’d estimate that doulas are still involved in only about 6%-8% of births,” said Shaconna Haley, MA, a certified holistic doula and doula trainer in Atlanta, Georgia.
And are there enough practicing doulas in the United States to put a dent in the current shortfall in pregnancy care? Although no reliable estimate of their numbers exists, a centralized online doula registration service listed 9000 registered practitioners in 2018. Contrast that with the approximately 3.6 million live births in 2023.
Potential for Friction?
Although generally seen as benign and helpful, the presence of a doula can add another layer of people for hard-pressed medical staff to deal with. Can their attendance occasionally lead to an adversarial encounter? Yes, said Dr. Baker, especially in the case of assertive questioning or suggestions directed at medical staff. “There can be some mistrust on the part of clinicians when nonmedical persons start raising concerns and asking questions. Staff can get a little prickly at this.”
In the view of Melissa A. Simon, MD, MPH, a professor of obstetrics and gynecology, preventive medicine, and medical social sciences at Northwestern University Feinberg School of Medicine in Chicago, Illinois, simple, preventable communication breakdown is often the cause of occasional antagonism. “As in all team care approaches, it’s helpful to have upfront conversations with the birthing person, the doula, and any care team members or support people who will be present in the birthing room. These conversations should be about expectations.”
According to Ms. Haley, “As long as the focus stays firmly on the client/patient and not on the other team members, there should be no friction. Medical staff should be aware there will be a doula in attendance and ideally there should be a collaborative team and plan in place before the birth.”
In Dr. Leke’s experience, doulas do not hinder the medical team as long as clinical roles are well clarified and the patient is engaged in her care plan. “Friction can occur when doulas are functioning outside of their scope of practice, such as speaking to the healthcare team on behalf of the mother instead empowering the mother to speak up herself,” she said. “Or, when the healthcare team doesn’t understand the doula’s scope of practice or recognize the doula as a member of the team.”
Added Dr. Rothenberg, “I’ve occasionally run into doulas who imagine I have an ulterior motive when making recommendations to patients when that’s completely untrue. It’s common for women to decide to become doulas because they didn’t feel listened to during their own birthing experience, and for a few of them, it’s hard to not project that onto their clients’ labor situations, creating conflict where it doesn’t need to exist.”
Barriers and Challenges
Unfortunately, the barriers of cost and access remain high for pregnant and birthing mothers from lower socioeconomic echelons who have no or limited insurance. “There also are very few multilingual doulas or doulas from diverse racial-ethnic backgrounds and identities,” Dr. Simon pointed out.
Yet by all indications, Medicaid members who receive doula services experience positive maternal outcomes, even those at higher risk for pregnancy complications.
As for Medicaid coverage of doula services, in a recent Centers for Medicare & Medicaid Services report, just 11 state Medicaid programs were reimbursing doula services, whereas an additional five were in the process of implementing reimbursement.
Doula care is not covered by all private insurance plans either, Dr. Simon said. “Although there are maternity care bundles with payment models that help integrate doula care, and there are ways to use your flexible spending account to cover it.”
Some hospitals may undertake independent initiatives. Dr. Baker’s center is offering antenatal and peripartum doula support for under-resourced mothers thanks to a Health Resources and Services Administration grant.*
But for now, doula services are largely limited to middle- and high-income women able to afford the associated out-of-pocket costs. These mothers are disproportionately White, and the doulas serving them tend to be of the same race and socioeconomic class.
The Future
Dr. Simon foresees an optimal scenario in which a team of doulas works with all birthing persons on a hospital labor floor as well as with a team of clinicians. “It takes a true team approach to ensure an optimal birthing experience and optimal birth outcomes,” she said.
Despite the many challenges ahead, doulas will probably become a permanent fixture in pregnancy, birth, and postpartum care, said Dr. Baker. “Doula care is going to be a game changer, and obstetricians welcome doulas to the obstetrical care team.”
Dr. Alrahmani, Dr. Baker, Ms. Haley, Dr. Leke, Dr. Rothenberg, and Dr. Simon declared no conflicts of interest relevant to their comments.

It’s well known that the United States enjoys the dubious distinction of having the worst maternal morbidity and mortality rates among industrialized nations. Maternal mortality in this country increased by 14% from 2018 to 2020, according to the Centers for Disease Control and Prevention’s National Center for Health Statistics.
But a current trend of engaging birth doulas — nonmedical guides offering continuous one-on-one physical and psychological support in the pre-, peri,- and postnatal periods — may be poised to brighten that dismal statistical landscape.
Recent research has shown that mothers matched with a doula are less likely to have a low birth weight baby, less likely to experience a birth complication, and significantly more likely to initiate breastfeeding.
Doula services — even delivered digitally — are seen to lower healthcare costs, reduce cesarean sections, decrease maternal anxiety and depression, and improve communication between healthcare providers and low-income, racially/ethnically diverse pregnant women. Doulas can be especially helpful for mothers dealing with the psychological fallout of miscarriage or stillbirth. They can guide patients in the postpartum period, when problems can arise and when some mothers are lost to medical follow-up, and provide an ongoing source of patient information for the ob.gyn.
“Research has shown that in addition to better outcomes, doula care can shorten labor time and increase patient satisfaction,” said ob.gyn. Layan Alrahmani, MD, in an interview. A maternal-fetal medicine specialist with a focus on high-risk pregnancies among low-income women at Loyola Medicine in Maywood, Illinois, Dr. Alrahmani welcomes doulas to her patients’ antenatal visits.

Healthy Lifestyle Mitigates Brain Aging in Diabetes
TOPLINE:
with brain age gaps of 2.29 and 0.50 years, respectively. This association is more pronounced in men and those with poor cardiometabolic health but may be mitigated by a healthy lifestyle.
METHODOLOGY:
- Diabetes is a known risk factor for cognitive impairment, dementia, and global brain atrophy but conflicting results have been reported for prediabetes, and it’s unknown whether a healthy lifestyle can counteract the negative impact of prediabetes.
- Researchers examined the cross-sectional and longitudinal relationship between hyperglycemia and brain aging, as well as the potential mitigating effect of a healthy lifestyle in 31,229 dementia-free adults (mean age, 54.8 years; 53% women) from the UK Biobank, including 13,518 participants with prediabetes and 1149 with diabetes.
- The glycemic status of the participants was determined by their medical history, medication use, and A1c levels.
- The brain age gap was calculated as a difference between chronologic age and brain age estimated from MRI data from six modalities vs several hundred brain MRI phenotypes that were modeled from a subset of healthy individuals.
- The role of sex, cardiometabolic risk factors, and a healthy lifestyle and their association with brain age was also explored, with a healthy lifestyle defined as never smoking, no or light or moderate alcohol consumption, and high physical activity.
TAKEAWAY:
- Prediabetes and diabetes were associated with a higher brain age gap than normoglycemia (beta-coefficient, 0.22 and 2.01; 95% CI, 0.10-0.34 and 1.70-2.32, respectively), and diabetes was more pronounced in men vs women and those with a higher vs lower burden of cardiometabolic risk factors.
- The brain ages of those with prediabetes and diabetes were 0.50 years and 2.29 years older on average than their respective chronologic ages.
- In an exploratory longitudinal analysis of the 2414 participants with two brain MRI scans, diabetes was linked to a 0.27-year annual increase in the brain age gap, and higher A1c, but not prediabetes, was associated with a significant increase in brain age gap.
- A healthy lifestyle attenuated the association between diabetes and a higher brain age gap (P = .003), reducing it by 1.68 years, also with a significant interaction between glycemic status and lifestyle.
IN PRACTICE:
“Our findings highlight diabetes and prediabetes as ideal targets for lifestyle-based interventions to promote brain health,” the authors wrote.
SOURCE:
This study, led by Abigail Dove, Aging Research Center, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Stockholm, Sweden, was published online in Diabetes Care.
LIMITATIONS:
The generalizability of the findings was limited due to a healthy volunteer bias in the UK Biobank. A high proportion of missing data prevented the inclusion of diet in the healthy lifestyle construct. Reverse causality may be possible as an older brain may contribute to the development of prediabetes by making it more difficult to manage medical conditions and adhere to a healthy lifestyle. A1c levels were measured only at baseline, preventing the assessment of changes in glycemic control over time.
DISCLOSURES:
The authors reported receiving funding from the Swedish Research Council; Swedish Research Council for Health, Working Life and Welfare; Karolinska Institutet Board of Research; Riksbankens Jubileumsfond; Marianne and Marcus Wallenberg Foundation; Alzheimerfonden; and Demensfonden. They declared no relevant conflicts of interest.

- Prediabetes and diabetes were associated with a higher brain age gap than normoglycemia (beta-coefficient, 0.22 and 2.01; 95% CI, 0.10-0.34 and 1.70-2.32, respectively), and diabetes was more pronounced in men vs women and those with a higher vs lower burden of cardiometabolic risk factors.
- The brain ages of those with prediabetes and diabetes were 0.50 years and 2.29 years older on average than their respective chronologic ages.
- In an exploratory longitudinal analysis of the 2414 participants with two brain MRI scans, diabetes was linked to a 0.27-year annual increase in the brain age gap, and higher A1c, but not prediabetes, was associated with a significant increase in brain age gap.
- A healthy lifestyle attenuated the association between diabetes and a higher brain age gap (P = .003), reducing it by 1.68 years, also with a significant interaction between glycemic status and lifestyle.
IN PRACTICE:
“Our findings highlight diabetes and prediabetes as ideal targets for lifestyle-based interventions to promote brain health,” the authors wrote.
SOURCE:
This study, led by Abigail Dove, Aging Research Center, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Stockholm, Sweden, was published online in Diabetes Care.
LIMITATIONS:
The generalizability of the findings was limited due to a healthy volunteer bias in the UK Biobank. A high proportion of missing data prevented the inclusion of diet in the healthy lifestyle construct. Reverse causality may be possible as an older brain may contribute to the development of prediabetes by making it more difficult to manage medical conditions and adhere to a healthy lifestyle. A1c levels were measured only at baseline, preventing the assessment of changes in glycemic control over time.

Does Preconception BMI Affect Time to Pregnancy and Miscarriage Risk?
TOPLINE:
Higher body mass index (BMI) in both partners is linked to lower fecundability and increased subfertility. Overweight and obesity in women are associated with higher odds of miscarriage.
METHODOLOGY:
- Researchers conducted a population-based prospective cohort study in Rotterdam, the Netherlands, from August 9, 2017, to July 1, 2021.
- A total of 3604 women and their partners were included, with follow-up until birth.
- BMI was measured in preconception or early pregnancy, and outcomes included fecundability, subfertility, and miscarriage.
- Fecundability was defined as the probability of conceiving within 1 month and subfertility as time to pregnancy or duration of actively pursuing pregnancy of more than 12 months or use of assisted reproductive technology.
- Miscarriage was defined as pregnancy loss before 22 weeks of gestation.
TAKEAWAY:
- Higher BMI in women and men was associated with lower fecundability: For every unit increase in BMI, fecundability decreased (women, 0.98; 95% CI, 0.97-0.99; men, 0.99; 95% CI, 0.98-1.00).
- Women with overweight (0.88; 95% CI, 0.80-0.98) and obesity (0.72; 95% CI, 0.63-0.82) had lower fecundability than women with normal weight.
- Overweight (1.35; 95% CI, 1.11-1.63) and obesity (1.67; 95% CI, 1.30-2.13) in women were associated with increased odds of subfertility.
- Obesity in men was associated with increased odds of subfertility (1.69; 95% CI, 1.24-2.31).
IN PRACTICE:
“We observed in this cohort study that BMI outside of the normal category in women and men was associated with lower fecundability, subfertility, and increased odds of miscarriage. Optimizing BMI from the preconception period onward in women and men might be an important strategy to improve fertility and pregnancy outcomes,” wrote the authors of the study.
SOURCE:
The study was led by Aline J. Boxem, MD, and Vincent W. V. Jaddoe, MD, PhD, The Generation R Study Group, Erasmus University Medical Centre in Rotterdam, the Netherlands. It was published online in JAMA Network Open.
LIMITATIONS:
The study’s generalizability may be affected by differences between included and excluded participants, who were younger and had a higher BMI. The accuracy of time-to-pregnancy duration may have been impacted by retrospectively answered questionnaires. Residual confounding might still be an issue due to the observational nature of the study.
DISCLOSURES:

Pertussis Rates Up Compared With Recent Years
, according to data from the Centers for Disease Control and Prevention (CDC). Reports from several states illustrate this trend, thought to be due to reduced immunity across the country.
The Alaska Department of Health issued a statement on its website about the significant increase in pertussis cases in the state during the summer, with 90 cases in July and 61 in August, compared with 24 in June and a total of 26 cases in 2023.
Similarly, the Florida Department of Health reported a pertussis increase in July 2024 that was higher than the June 2024 case count and also above the previous 5-year average.
Experts in these and other states suggest that several factors are driving the nationwide increase, including the fact that fewer people are consistently wearing masks. The mass masking during the COVID-19 pandemic caused a significant drop in pertussis, but the latest data suggest a return to prepandemic levels, and waning immunity likely plays a role as well.
Pertussis, also known as whooping cough, typically begins with symptoms similar to those of the common cold, including runny nose, sneezing, mild fever, and cough, according to the CDC. However, babies with whooping cough may experience trouble breathing rather than a cough. The coughing fits often associated with pertussis may not start until 2 weeks after the onset of other symptoms, according to the CDC.
Those who have been vaccinated against pertussis can still become infected, but the risk is lower, and the illness, if it occurs, is likely to be milder. Complications such as apnea, pneumonia, and convulsions can occur in babies younger than 1 year, especially if they have not been vaccinated, according to the CDC.
Beyond Easing Pandemic Precautions
Many respiratory-based infections dipped during the COVID-19 pandemic, almost certainly from the multifactorial interventions of masking, distancing, and the general lack of comingling, said David J. Cennimo, MD, associate professor of medicine & pediatrics in the Division of Infectious Diseases at Rutgers New Jersey Medical School, Newark, New Jersey, in an interview.
The number of cases of many of these diseases returned to previous levels after COVID-19 restrictions were lifted, he said.
“However, we know pertussis immunity wanes over time. Children get DTaP at 2, 4, 6, and 15 months, and a Tdap booster at 11-12 years old gets them to adulthood,” Dr. Cennimo said. Adults should be getting a Tdap every 10 years, he added.
The latest available CDC data indicate that Tdap vaccine coverage in adults is approximately 40%, which means that there may be a large number of susceptible people who can become infected and propagate to others, said Dr. Cennimo.
Not Just the Young Ones
A recent pertussis outbreak among college students in Virginia highlighted the fact that the infection can affect all ages, and that the effectiveness of childhood vaccines may decrease over time. The majority of the recently diagnosed cases occurred in individuals who had been previously vaccinated, according to a press release from the Virginia Department of Health.
Clinical Clues
The initial stage of pertussis infection looks like a common cold with symptoms of upper respiratory infection, Dr. Cennimo told this news organization. “Unless there is reason to suspect pertussis exposure, it would almost certainly be missed,” he noted.
The characteristic barking/seal-like cough is mostly seen in children, said Dr. Cennimo. Adults and children can experience coughing fits that can lead to shortness of breath and/or vomiting, which would raise suspicion for pertussis, but is not universally present, he said. The convalescent stage of pertussis can be prolonged and is characterized by chronic coughing. “In the past, pertussis had been called the 100-day cough,” and at that point, treatment is ineffective, Dr. Cennimo said.
In clinical practice, “I advise everyone to get the Tdap vaccine every 10 years,” and remember that the “Td” is the every 10-year tetanus shot as well, Dr. Cennimo told this news organization. Reassure patients that the Tdap can be given with other vaccines, he said, and remind patients that, as with any of the respiratory illnesses, they should stay home if sick, cover a cough, consider wearing a mask in public, and wash hands frequently, he said.
Dr. Cennimo had no financial conflicts to disclose.

A 71-year-old White female developed erosions after hip replacement surgery 2 months prior to presentation
The patient had been diagnosed with pemphigus vulgaris (PV) 1 year prior to presentation with erosions on the axilla. Biopsy at that time revealed intraepithelial acantholytic blistering with areas of suprabasilar and subcorneal clefting. Direct immunofluorescence was positive for linear/granular IgG deposition throughout the epithelial cell surfaces, as well as linear/granular C3 deposits of the lower two thirds of the epithelial strata, consistent for pemphigus vulgaris.
There is likely a genetic predisposition. Medications that may induce pemphigus include penicillamine, nifedipine, or captopril.
Clinically, PV presents with flaccid blistering lesions that may be cutaneous and/or mucosal. Bullae can progress to erosions and crusting, which then heal with pigment alteration but not scarring. The most commonly affected sites are the mouth, intertriginous areas, face, and neck. Mucosal lesions can involve the lips, esophagus, conjunctiva, and genitals.
Biopsy for histology and direct immunofluorescence is important in distinguishing between PV and other blistering disorders. Up to 75% of patients with active disease also have a positive indirect immunofluorescence with circulating IgG.
There are numerous reports in the literature of PV occurring in previous surgical scars, and areas of friction or trauma. This so-called Koebner’s phenomenon is seen more commonly in several dermatologic conditions, such as psoriasis, lichen planus, verruca vulgaris, and vitiligo.
Treatment for PV is generally immunosuppressive. Systemic therapy usually begins with prednisone and then is transitioned to a steroid sparing agent such as mycophenolate mofetil. Other steroid sparing agents include azathioprine, methotrexate, cyclophosphamide, and intravenous immunoglobulin. Secondary infections are possible and should be treated. Topical therapies aimed at reducing pain, especially in mucosal lesions, can be beneficial.

Myth of the Month: Vitamin C vs the Common Cold
Case: A 38-year-old presents for acute onset runny nose, cough, and fever for the last 3 days. Her children at home have a similar presentation. She believes that she has been managing her symptoms well with Tylenol and rest. The patient is up to date on her COVID and flu shots and was wondering if there was anything else she could have done to prevent her symptoms. She saw a commercial about vitamin C supplements boosting the immune system and was wondering about their efficacy. How would you respond?
Studies of Vitamin C
Linus Pauling, FRS, did a summary of four relatively small published studies of vitamin C and concluded that vitamin C supplementation helped prevent and lessen colds.1 He mentioned a placebo-controlled study of vitamin C with viral inoculation which did not show any effect. His overall conclusion of efficacy for vitamin C led to the widespread belief that vitamin C was a proven effective therapy to prevent and treat the common cold. Since then, multiple trials and studies have examined the effect of vitamin C on the prevention and treatment of colds.
The Cochrane Review conducted a meta-analysis comparing 29 placebo-controlled trials involving 11,306 participants.2 Criteria included vitamin C supplementation of 0.2 g-1 g/day to study its efficacy in preventing the common cold. The analysis showed that supplemental vitamin C did not significantly reduce the incidence of colds. However, there was a statistically significant 8% reduction in adults and 14% in children in the duration of colds. In terms of treatment, there was no evidence of vitamin C’s efficacy.
A 2001 study conducted a small double-blind, randomized control trial to evaluate large doses of vitamin C as treatment for the common cold.3 Volunteers were divided and instructed to take varying doses ranging from 1 to 3 g of vitamin C vs a placebo at the onset of cold-like symptoms. Subjects were expected to assess the duration and severity of their cold. The data showed no significant difference in the severity or duration of cold symptoms between small or large vitamin C doses or placebo.
A more recent meta-analysis by Hemilä and Chalker looked at 10 placebo-controlled trials of vitamin C for the prevention and treatment of colds.4 The analysis showed a small 15% reduction in more severe cold symptoms.
Summary
While vitamin C is safe, there is no evidence for its ability to prevent the common cold. Although the Cochrane review and more a recent meta-analysis by Hemilä and Chalker demonstrated statistical significance in shortening the duration of symptoms, it was a minimal reduction with little clinical significance. .

Case: A 38-year-old presents for acute onset runny nose, cough, and fever for the last 3 days. Her children at home have a similar presentation. She believes that she has been managing her symptoms well with Tylenol and rest. The patient is up to date on her COVID and flu shots and was wondering if there was anything else she could have done to prevent her symptoms. She saw a commercial about vitamin C supplements boosting the immune system and was wondering about their efficacy. How would you respond?
Studies of Vitamin C
Linus Pauling, FRS, did a summary of four relatively small published studies of vitamin C and concluded that vitamin C supplementation helped prevent and lessen colds.1 He mentioned a placebo-controlled study of vitamin C with viral inoculation which did not show any effect. His overall conclusion of efficacy for vitamin C led to the widespread belief that vitamin C was a proven effective therapy to prevent and treat the common cold. Since then, multiple trials and studies have examined the effect of vitamin C on the prevention and treatment of colds.
The Cochrane Review conducted a meta-analysis comparing 29 placebo-controlled trials involving 11,306 participants.2 Criteria included vitamin C supplementation of 0.2 g-1 g/day to study its efficacy in preventing the common cold. The analysis showed that supplemental vitamin C did not significantly reduce the incidence of colds. However, there was a statistically significant 8% reduction in adults and 14% in children in the duration of colds. In terms of treatment, there was no evidence of vitamin C’s efficacy.
A 2001 study conducted a small double-blind, randomized control trial to evaluate large doses of vitamin C as treatment for the common cold.3 Volunteers were divided and instructed to take varying doses ranging from 1 to 3 g of vitamin C vs a placebo at the onset of cold-like symptoms. Subjects were expected to assess the duration and severity of their cold. The data showed no significant difference in the severity or duration of cold symptoms between small or large vitamin C doses or placebo.
A more recent meta-analysis by Hemilä and Chalker looked at 10 placebo-controlled trials of vitamin C for the prevention and treatment of colds.4 The analysis showed a small 15% reduction in more severe cold symptoms.

Bimekizumab Gains FDA Approval for Psoriatic Arthritis, Axial Spondyloarthritis
The Food and Drug Administration has approved bimekizumab-bkzx (Bimzelx; UCB) for adult patients with active psoriatic arthritis (PsA), active nonradiographic axial spondyloarthritis (nr-axSpA) with objective signs of inflammation, and active ankylosing spondylitis (AS).
The drug, an interleukin (IL)–17A and IL-17F inhibitor, was first approved in October 2023 for treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.
“In psoriatic arthritis and across the spectrum of axSpA, clinical study results and real-world experience outside the US have highlighted that Bimzelx can help patients achieve high thresholds of clinical response that are rapid in onset and sustained up to 2 years,” said Emmanuel Caeymaex, executive vice president, head of patient impact, and chief commercial officer of UCB in a press release.
The recommended dosage of bimekizumab for adult patients with active PsA, nr-axSpA, or AS is 160 mg by subcutaneous injection every 4 weeks. For patients with PsA and coexistent moderate to severe plaque psoriasis, the dosage is the same as for patients with plaque psoriasis. The dosing for plaque psoriasis is to administer 320 mg (two 160-mg injections) by subcutaneous injection at weeks 0, 4, 8, 12, and 16, then every 8 weeks thereafter. For patients weighing ≥ 120 kg, consider a dose of 320 mg every 4 weeks after week 16.
PsA Clinical Trials
The approval for PsA was based on data from two phase 3 clinical trials, including 852 participants naive to biologics (BE OPTIMAL) and 400 participants with inadequate response to treatment with one or two tumor necrosis factor (TNF) inhibitors (BE COMPLETE). Both studies met their primary endpoint, 50% improvement in American College of Rheumatology response criteria (ACR50) at 16 weeks, as well as ranked secondary endpoints. Secondary endpoints included minimal disease activity (MDA) and Psoriasis Area and Severity Index 100 (complete skin clearance) at week 16.
At 16 weeks:
- About 44% of both the biologic-naive (189 of 431) and TNF inhibitor–resistant (116 of 267) groups receiving bimekizumab achieved ACR50 response, compared with 10% (28 of 281) and 7% (9 of 133) receiving placebo, respectively.
- About 45% of all patients treated with bimekizumab achieved MDA.
- Nearly 60% of TNF inhibitor–resistant patients had complete skin clearance.
These responses generally were sustained for 1 year. The most common adverse reactions are upper respiratory tract infections, oral candidiasis, headache, diarrhea, and urinary tract infection.
NR-axSpA and AS Clinical Trials
The approval for active nr-axSpA and active AS was based on data from two clinical studies, BE MOBILE 1 (nr-axSpA) and BE MOBILE 2 (AS). Both studies met their primary endpoint, 40% improvement in Assessment of Spondyloarthritis International Society response criteria (ASAS40) at 16 weeks.
Key findings included:
- In nr-axSpA patients, 47.7% (61 of 128) receiving bimekizumab achieved ASAS40 at week 16, compared with 21.4% (27 of 126) receiving placebo.
- In AS patients, 44.8% (99 of 221) in the bimekizumab group achieved ASAS40 response at week 16 vs 22.5% (25 of 111) receiving placebo.
- At 1 year in both groups, 60% treated with bimekizumab achieved an Ankylosing Spondylitis Disease Activity Score < 2.1.
In nr-axSpA, the most common adverse reactions are upper respiratory tract infections, oral candidiasis, headache, diarrhea, cough, fatigue, musculoskeletal pain, myalgia, tonsillitis, increase in transaminase, and urinary tract infection. In AS, the most common adverse reactions are upper respiratory tract infections, oral candidiasis, headache, diarrhea, injection-site pain, rash, and vulvovaginal mycotic infection.
Bimekizumab was approved by the European Commission for the same rheumatologic indications in June 2023.
Bimekizumab is currently available to eligible patients in the United States, according to the press release.
