First Brain-Injected Gene Therapy Approved by FDA
The US Food and Drug Administration (FDA) has granted fast-track approval for a groundbreaking gene therapy indicated for a rare genetic disorder called aromatic L-amino acid decarboxylase (AADC) deficiency. The gene therapy, marketed under the brand name Kebilidi, is the first in the United States to be injected directly into the brain. It is approved for children with fully developed skulls and for adults.
AADC is an enzyme that helps the body make dopamine. AADC deficiency affects patients’ physical, mental, and behavioral health from infancy, leading to severe disabilities and shorter lifespan. Children with AADC may also experience painful seizure-like episodes called oculogyric crises.
Kebilidi (generic name: eladocagene exuparvovec) is injected into a specific area of the brain where it boosts AADC, restoring dopamine production and gradually improving movement-related symptoms. This surgery is to be performed only by brain surgeons in specialized centers.
The FDA approval was based on the therapy’s safety and effectiveness as shown in an ongoing clinical trial involving 13 children diagnosed with AADC deficiency. According to PTC Therapeutics, the maker of Kebilidi, long-term follow-up studies of the participants are still needed, and additional proof of the therapy’s benefits are required for full FDA approval.
Common side effects of Kebilidi therapy may include involuntary movements (dyskinesia), anemia, fever, low blood pressure, excessive salivation, problems sleeping, low blood levels of certain minerals, and complications after the injection, including breathing or heart problems. The surgical procedure for injecting Kebilidi also carries certain risks, such as cerebrospinal fluid leaks, bleeding in the brain, inflammation, strokes, and infections.

Need for Low-Dose Steroids to Prevent Relapse in GPA Vasculitis Depends on Treatment Regimen
WASHINGTON — Patients with granulomatosis with polyangiitis (GPA) completely tapered off prednisone have a more than fourfold risk of relapse by 6 months, compared with those tapered to 5 mg/day of prednisone; however, this benefit was only seen in patients not on rituximab, according to new research presented at the annual meeting of the American College of Rheumatology (ACR).
“For patients treated with rituximab, fully tapering off glucocorticoids is reasonable to consider as the first approach,” said Peter Merkel, MD, MPH, chief of the division of rheumatology at the University of Pennsylvania, Philadelphia, during his presentation of the findings.
Although a low dose of glucocorticoids can prevent some minor relapses in patients on other treatment regimens such as methotrexate or azathioprine, “fully tapering off prednisone presents relatively little risk of major relapse, and that major relapse can be treated rather quickly,” Merkel added.
The Assessment of Prednisone in Remission (TAPIR) trial enrolled 143 patients with GPA who were in remission (defined as a Birmingham Vasculitis Activity Score for Wegener’s Granulomatosis [BVAS/WG] of 0) within 1 year of treatment to induce remission for active disease and who were taking 5-10 mg of prednisone per day. After all patients tapered to 5 mg/day of prednisone, 71 patients completely tapered off prednisone over 4 weeks and remained off glucocorticoids until month 6. The remaining patients maintained a 5-mg/day dose over the study period. Placement in either treatment group was randomized, and patients continued other immunosuppressive therapy during the study.
Researchers evaluated the rate of relapse by 6 months, defined as a physician’s decision to increase the dose of glucocorticoids to treat GPA, in both groups.
Across all participants, the median age was 58 years, and 52% of patients were male. Most patients were White, and 47% of all patients were prescribed rituximab.
At 6 months, 15.5% of participants who completely tapered off prednisone experienced a relapse of GPA, compared with 4.2% of those taking low-dose prednisone. Time to relapse was also shorter in the 0-mg prednisone group (P = .026), and relapses occurred continually over 6 months, Merkel said.
When stratified by rituximab use, relapse rates at 6 months between the 5-mg and 0-mg prednisone groups in patients taking rituximab showed no difference. Among patients not taking rituximab, those who completely stopped prednisone were nine and a half times as likely to experience relapse as those in the low-dose group.
Despite these differences in relapse rates, “surprisingly, there were no differences in patient-reported outcomes [such as pain interference, physical function, and fatigue],” Merkel said.
Across all patients, all but one relapse was characterized as minor. There were five serious adverse events and 10 infections in the 0-mg group versus one adverse event and 4 infections in the 5-mg group, but these differences were not statistically significant.
In patients who relapsed, musculoskeletal and ear, nose, and throat manifestations of GPA were most common, and these are “the kind of stuff we see that is helped by low-dose glucocorticoids,” Merkel said.
It’s a good sign that for patients who were completely weaned off glucocorticoids, nearly all relapses were minor, Galina Marder, MD, a rheumatologist and associate professor of medicine at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Hempstead, New York, said in an interview. She was not involved with the research.
The study “can reinforce the message [of] trying to get them off steroids completely [when possible],” she said.
The findings also provide insight for future clinical trials, Merkel noted. For patients taking non–rituximab-based regimens, completely tapering off glucocorticoids or maintaining a low dose can affect study outcomes.
“[These data are] even more important for clinical trials because they are [reinforcing] the fact that you can have a diminishing signal if you allow some patients to stay on 5 mg prednisone” when GPA flares are the primary outcome, Marder added.
The Vasculitis Clinical Research Consortium received funding for this research through grants from the National Institutes of Health. Merkel has disclosed financial relationships with AbbVie/Abbott, Amgen, argenx, AstraZeneca, Boehringer Ingelheim, Bristol Myers Squibb, Cabaletta, ChemoCentryx, CSL Behring, Dynacure, Eicos, Electra, EMD Serono, Forbius, Genentech/Roche, Genzyme/Sanofi, GSK, HI-Bio, Inmagene, InflaRx, Janssen, Kiniksa, Kyverna, Magenta, MiroBio, Neutrolis, Novartis, NS Pharma, Pfizer, Regeneron, Sanofi, Sparrow, Takeda, Talaris, UpToDate, and Visterra.

FROM ACR 2024
First Phase 3 Drug Trial in IgG4-Related Disease Has Success
WASHINGTON — The B cell–depleting agent inebilizumab (Uplizna) dramatically reduced the risk of flares and increased year-long remission of IgG4-related disease (RD), new research has found.
In a phase 3, multicenter, double-blind, randomized, placebo-controlled trial of 135 adults with active IgG4-RD, treatment with inebilizumab resulted in a significant 87% reduction in flare risk and nearly fivefold greater likelihood of flare-free remission at 1 year. The results were published online November 14 in The New England Journal of Medicine and were presented at the annual meeting of the American College of Rheumatology (ACR).
The drug’s manufacturer, Amgen, released top-line results of the trial, called MITIGATE, in June 2024.
Until now, the mainstay of management for the chronic multiorgan disease IgG4-RD has been glucocorticoids, which can cause numerous adverse effects. “It is hoped that inebilizumab can be used as an important steroid-sparing medication in this disease to reduce steroid toxicity,” lead author John H. Stone, MD, professor of medicine at Harvard Medical School, Boston, Massachusetts, said in an interview, noting that it may not entirely eliminate the need for steroid treatment, but for many, it appears to work after the remission induction period as a monotherapy without steroids.
Asked to comment, Leonard H. Calabrese, DO, head of the Section of Clinical Immunology and manager of the Clinical Immunology Clinic at the Cleveland Clinic, Ohio, said: “There has been anecdotal or observational evidence for some effect with other immunosuppressive agents, including rituximab, but no robust clinical trial until this study. This clearly has demonstrated efficacy by reducing the risk of flares. And most importantly, putting people into remission means no active disease in any given organ. ... This gives us another tool in the toolbox to attack B cell–directed diseases, and I think it really makes a lot of sense.”
Calabrese cautioned, though, that “this is a disease that extends over many years. This is just a 1-year study. Label extensions will be important.”
And several questions remain, Calabrese noted: “How long do patients need to remain on drug? What will happen when the drug is stopped? Can they be retreated? These are the natural questions that arise in any sentinel study like this. But this is extremely encouraging. And I think it’s great for patients. I also think it’s a clarion call to increase awareness about this disease since there’s now strong evidence of effective treatment.”
Underrecognized, Often Misdiagnosed as Cancer
Indeed, IgG4-RD, a chronic, relapsing, autoimmune, fibro-inflammatory multiorgan disease, was only first described in Japan in 2003. Since then, it has been reported all over the world yet remains vastly underrecognized. It is often misdiagnosed as cancer because it produces lesions in multiple organs. It received an ICD-10 code only about a year ago. A previous study estimated a prevalence of about 5.3 persons per 100,000 but that is likely to be a three- to fourfold underestimate, said Stone, who is also executive chairman of the IgG4ward! Foundation.
“Nobody had heard of the disease until about 20 years ago. ... And there are many people in the world who have still not heard of it despite the fact that it is a multiorgan autoimmune disease and is probably as common, or more common, than many other diseases that rheumatologists spend a lot of time thinking about, such as scleroderma.”
While knowledge about the disease is increasing in rheumatology circles, it’s less well-recognized among many of the specialties where patients present, depending on the location of their lesions. These include gastroenterology, ophthalmology, pulmonary medicine, neurology, and nephrology. “All would be likely to see this disease,” Stone said.
The disease can be mistaken for tumors in many of those locations and even as metastatic cancer, he noted, adding that “any time a patient has a mass lesion in a typical organ, the pancreas, the major salivary glands, the lungs, or the kidneys, this should be on the differential diagnosis.”
The diagnosis of IgG4-RD is a clinical one, involving “quadrangulation between clinical features, serological findings, IgG4 levels in the blood, radiology studies, and then pathology biopsies when those are available,” Stone said.
Calabrese characterized the current situation as “we’re all blind men on the elephant. To the neurologist or the neurosurgeon, it’s a mass in the brain. It could present to the ophthalmologist as an [eye] tumor. It can be thyroid gland failure, pulmonary disease, retroperitoneal fibrosis, hepatobiliary disease, and beyond. So, whoever sees that patient, there’s often a long lag time in recognizing it.”
And interestingly, Stone noted that unlike other autoimmune diseases, IgG4-RD primarily affects middle-aged men rather than younger-to-middle-aged women. And when IgG4-RD is diagnosed, glucocorticoid treatment can be particularly toxic when the pancreas is involved, heightening the risk for hyperglycemia and potentially causing diabetes.
Dramatic Improvement in Flares, Remission Achievement
MITIGATE is a phase 3, multicenter, double-blind, randomized, placebo-controlled trial in which 135 adults (mean age 58.2 years, 88 men) with active IgG4-RD were randomized 1:1 to receive 300-mg intravenous infusions of inebilizumab or placebo on days 1 and 15, and again at week 26. At baseline, 62 (45.9%) participants had newly diagnosed IgG4-RD and 73 (54.1%) had recurrent disease.
Both groups received identical glucocorticoid tapers. Overall, 127 (94.1%) completed the 52 weeks of treatment.
By 52 weeks, only seven patients in the inebilizumab group (10%) had experienced disease flares vs 40 (60%) in the placebo group, a significant difference with a hazard ratio of 0.13 (P < .001).
The percentage of participants achieving flare-free, treatment-free complete remission was 59 with inebilizumab (57%), compared with just 15 (22%) in the placebo group (odds ratio [OR], 4.68; P < .001). And for flare-free, glucocorticoid-free complete remission, those proportions were 40 (59%) vs 15 (22%), respectively (OR, 4.96; P < .001).
Excluding the 8-week glucocorticoid taper period, mean total glucocorticoid use was 1264.2 mg less in the inebilizumab than the placebo group, a significant reduction. Overall, 61 participants (90%) were able to entirely discontinue glucocorticoids during the trial, compared with just 25 (37%) in the placebo group.
Adverse events of grade 3 or higher occurred in 12 participants (18%) in the inebilizumab group and 8 (12%) in the placebo group; serious adverse events occurred in 12 (18%) and 6 (9%), respectively. However, no serious adverse event occurred in more than one participant, and there were no deaths. Adverse events led to withdrawal from the trial in six patients (9%) in the inebilizumab group and three patients (4%) in the placebo group.
Adverse events that occurred in more than 10% of participants in the inebilizumab group were COVID-19 in 16 participants (24%), lymphopenia in 11 (16%), and urinary tract infection in 8 (12%).
Importantly, Stone noted, B-cell depletion can reduce responses to vaccines, so patients should receive all recommended vaccinations, including COVID-19, influenza, respiratory syncytial virus, and others, prior to initiating therapy.
Uplizna (inebilizumab-cdon) was approved by the Food and Drug Administration (FDA) for the treatment of neuromyelitis optica spectrum disorder in 2020. In October 2024, the FDA granted Amgen breakthrough therapy designation for use in IgG4-RD. The company is also developing the drug for use in myasthenia gravis.
The study was funded by Amgen. Stone has reported being a consultant for Amgen, Zenas, Argenx, Bristol Myers Squibb, Novartis, Sanofi, and Horizon Pharma. Calabrese has reported being a consultant and/or speaker for Amgen, AstraZeneca, Jansen, Sanofi, and UCB.

Overall, 61 participants (90%) were able to entirely discontinue glucocorticoids during the trial, compared with just 25 (37%) in the placebo group.
Adverse events of grade 3 or higher occurred in 12 participants (18%) in the inebilizumab group and 8 (12%) in the placebo group; serious adverse events occurred in 12 (18%) and 6 (9%), respectively. However, no serious adverse event occurred in more than one participant, and there were no deaths. Adverse events led to withdrawal from the trial in six patients (9%) in the inebilizumab group and three patients (4%) in the placebo group.
Adverse events that occurred in more than 10% of participants in the inebilizumab group were COVID-19 in 16 participants (24%), lymphopenia in 11 (16%), and urinary tract infection in 8 (12%).
Importantly, Stone noted, B-cell depletion can reduce responses to vaccines, so patients should receive all recommended vaccinations, including COVID-19, influenza, respiratory syncytial virus, and others, prior to initiating therapy.
Uplizna (inebilizumab-cdon) was approved by the Food and Drug Administration (FDA) for the treatment of neuromyelitis optica spectrum disorder in 2020. In October 2024, the FDA granted Amgen breakthrough therapy designation for use in IgG4-RD. The company is also developing the drug for use in myasthenia gravis.
The study was funded by Amgen. Stone has reported being a consultant for Amgen, Zenas, Argenx, Bristol Myers Squibb, Novartis, Sanofi, and Horizon Pharma. Calabrese has reported being a consultant and/or speaker for Amgen, AstraZeneca, Jansen, Sanofi, and UCB.

WASHINGTON — The B cell–depleting agent inebilizumab (Uplizna) dramatically reduced the risk of flares and increased year-long remission of IgG4-related disease (RD), new research has found.
In a phase 3, multicenter, double-blind, randomized, placebo-controlled trial of 135 adults with active IgG4-RD, treatment with inebilizumab resulted in a significant 87% reduction in flare risk and nearly fivefold greater likelihood of flare-free remission at 1 year. The results were published online November 14 in The New England Journal of Medicine and were presented at the annual meeting of the American College of Rheumatology (ACR).
The drug’s manufacturer, Amgen, released top-line results of the trial, called MITIGATE, in June 2024.
Until now, the mainstay of management for the chronic multiorgan disease IgG4-RD has been glucocorticoids, which can cause numerous adverse effects. “It is hoped that inebilizumab can be used as an important steroid-sparing medication in this disease to reduce steroid toxicity,” lead author John H. Stone, MD, professor of medicine at Harvard Medical School, Boston, Massachusetts, said in an interview, noting that it may not entirely eliminate the need for steroid treatment, but for many, it appears to work after the remission induction period as a monotherapy without steroids.
Asked to comment, Leonard H. Calabrese, DO, head of the Section of Clinical Immunology and manager of the Clinical Immunology Clinic at the Cleveland Clinic, Ohio, said: “There has been anecdotal or observational evidence for some effect with other immunosuppressive agents, including rituximab, but no robust clinical trial until this study. This clearly has demonstrated efficacy by reducing the risk of flares. And most importantly, putting people into remission means no active disease in any given organ. ... This gives us another tool in the toolbox to attack B cell–directed diseases, and I think it really makes a lot of sense.”
Calabrese cautioned, though, that “this is a disease that extends over many years. This is just a 1-year study. Label extensions will be important.”
And several questions remain, Calabrese noted: “How long do patients need to remain on drug? What will happen when the drug is stopped? Can they be retreated? These are the natural questions that arise in any sentinel study like this. But this is extremely encouraging. And I think it’s great for patients. I also think it’s a clarion call to increase awareness about this disease since there’s now strong evidence of effective treatment.”
Underrecognized, Often Misdiagnosed as Cancer
Indeed, IgG4-RD, a chronic, relapsing, autoimmune, fibro-inflammatory multiorgan disease, was only first described in Japan in 2003. Since then, it has been reported all over the world yet remains vastly underrecognized. It is often misdiagnosed as cancer because it produces lesions in multiple organs. It received an ICD-10 code only about a year ago. A previous study estimated a prevalence of about 5.3 persons per 100,000 but that is likely to be a three- to fourfold underestimate, said Stone, who is also executive chairman of the IgG4ward! Foundation.
“Nobody had heard of the disease until about 20 years ago. ... And there are many people in the world who have still not heard of it despite the fact that it is a multiorgan autoimmune disease and is probably as common, or more common, than many other diseases that rheumatologists spend a lot of time thinking about, such as scleroderma.”
While knowledge about the disease is increasing in rheumatology circles, it’s less well-recognized among many of the specialties where patients present, depending on the location of their lesions. These include gastroenterology, ophthalmology, pulmonary medicine, neurology, and nephrology. “All would be likely to see this disease,” Stone said.
The disease can be mistaken for tumors in many of those locations and even as metastatic cancer, he noted, adding that “any time a patient has a mass lesion in a typical organ, the pancreas, the major salivary glands, the lungs, or the kidneys, this should be on the differential diagnosis.”
The diagnosis of IgG4-RD is a clinical one, involving “quadrangulation between clinical features, serological findings, IgG4 levels in the blood, radiology studies, and then pathology biopsies when those are available,” Stone said.
Calabrese characterized the current situation as “we’re all blind men on the elephant. To the neurologist or the neurosurgeon, it’s a mass in the brain. It could present to the ophthalmologist as an [eye] tumor. It can be thyroid gland failure, pulmonary disease, retroperitoneal fibrosis, hepatobiliary disease, and beyond. So, whoever sees that patient, there’s often a long lag time in recognizing it.”
And interestingly, Stone noted that unlike other autoimmune diseases, IgG4-RD primarily affects middle-aged men rather than younger-to-middle-aged women. And when IgG4-RD is diagnosed, glucocorticoid treatment can be particularly toxic when the pancreas is involved, heightening the risk for hyperglycemia and potentially causing diabetes.
Dramatic Improvement in Flares, Remission Achievement
MITIGATE is a phase 3, multicenter, double-blind, randomized, placebo-controlled trial in which 135 adults (mean age 58.2 years, 88 men) with active IgG4-RD were randomized 1:1 to receive 300-mg intravenous infusions of inebilizumab or placebo on days 1 and 15, and again at week 26. At baseline, 62 (45.9%) participants had newly diagnosed IgG4-RD and 73 (54.1%) had recurrent disease.
Both groups received identical glucocorticoid tapers. Overall, 127 (94.1%) completed the 52 weeks of treatment.
By 52 weeks, only seven patients in the inebilizumab group (10%) had experienced disease flares vs 40 (60%) in the placebo group, a significant difference with a hazard ratio of 0.13 (P < .001).
The percentage of participants achieving flare-free, treatment-free complete remission was 59 with inebilizumab (57%), compared with just 15 (22%) in the placebo group (odds ratio [OR], 4.68; P < .001). And for flare-free, glucocorticoid-free complete remission, those proportions were 40 (59%) vs 15 (22%), respectively (OR, 4.96; P < .001).
Excluding the 8-week glucocorticoid taper period, mean total glucocorticoid use was 1264.2 mg less in the inebilizumab than the placebo group, a significant reduction. Overall, 61 participants (90%) were able to entirely discontinue glucocorticoids during the trial, compared with just 25 (37%) in the placebo group.
Adverse events of grade 3 or higher occurred in 12 participants (18%) in the inebilizumab group and 8 (12%) in the placebo group; serious adverse events occurred in 12 (18%) and 6 (9%), respectively. However, no serious adverse event occurred in more than one participant, and there were no deaths. Adverse events led to withdrawal from the trial in six patients (9%) in the inebilizumab group and three patients (4%) in the placebo group.
Adverse events that occurred in more than 10% of participants in the inebilizumab group were COVID-19 in 16 participants (24%), lymphopenia in 11 (16%), and urinary tract infection in 8 (12%).

FROM ACR 2024
Scurvy: A Diagnosis Still Relevant Today
“Petechial rash often prompts further investigation into hematological, dermatological, or vasculitis causes. However, if the above investigations are negative and skin biopsy has not revealed a cause, there is a Renaissance-era diagnosis that is often overlooked but is easily investigated and treated,” wrote Andrew Dermawan, MD, and colleagues from Sir Charles Gairdner Hospital in Nedlands, Australia, in BMJ Case Reports. The diagnosis they highlight is scurvy, a disease that has faded from common medical concern but is reemerging, partly because of the rise in bariatric surgery.
Diagnosing Scurvy in the 2020s
In their article, Dermawan and colleagues present the case of a 50-year-old man with a bilateral petechial rash on his lower limbs, without any history of trauma. The patient, who exhibited no infectious symptoms, also had gross hematuria, microcytic anemia, mild neutropenia, and lymphopenia. Tests for autoimmune and hematological diseases were negative, as were abdominal and leg CT scans, ruling out abdominal hemorrhage and vasculitis. Additionally, a skin biopsy showed no causative findings.
The doctors noted that the patient had undergone sleeve gastrectomy, prompting them to inquire about his diet. They discovered that, because of financial difficulties, his diet primarily consisted of processed foods with little to no fruits or vegetables, and he had stopped taking supplements recommended by his gastroenterologist. Further tests revealed a vitamin D deficiency and a severe deficiency in vitamin C. With the diagnosis of scurvy confirmed, the doctors treated the patient with 1000 mg of ascorbic acid daily, along with cholecalciferol, folic acid, and a multivitamin complex, leading to a complete resolution of his symptoms.
Risk Factors Then and Now
It can cause mucosal and gastric hemorrhages, and if left untreated, it can lead to fatal bleeding.
Historically known as “sailors’ disease,” scurvy plagued men on long voyages who lacked access to fresh fruits or vegetables and thus did not get enough vitamin C. In 1747, James Lind, a British physician in the Royal Navy, demonstrated that the consumption of oranges and lemons could combat scurvy.
Today’s risk factors for scurvy include malnutrition, gastrointestinal disorders (eg, chronic inflammatory bowel diseases), alcohol and tobacco use, eating disorders, psychiatric illnesses, dialysis, and the use of medications that reduce the absorption of ascorbic acid (such as corticosteroids and proton pump inhibitors).
Scurvy remains more common among individuals with unfavorable socioeconomic conditions. The authors of the study emphasize how the rising cost of living — specifically in Australia but applicable elsewhere — is changing eating habits, leading to a high consumption of low-cost, nutritionally poor foods.
Poverty has always been a risk factor for scurvy, but today there may be an additional cause: bariatric surgery. Patients undergoing these procedures are at a risk for deficiencies in fat-soluble vitamins A, D, E, and K, and if their diet is inadequate, they may also experience a vitamin C deficiency. Awareness of this can facilitate the timely diagnosis of scurvy in these patients.

Myasthenia Gravis: Where Does Traditional Therapy Fit In?
SAVANNAH, GEORGIA —
In a debate at American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024, a pair of neurologists who specialize in neuromuscular disorders laid out opposing evidence for each approach.
On one hand, Benjamin Claytor, MD, of Cleveland Clinic, Cleveland, argued that “traditional therapy is very effective for the majority of myasthenia gravis patients,” and he said it should be considered first-line.
But Amanda C. Guidon, MD, MPH, of Massachusetts General Hospital and Harvard Medical School, both in Boston, responded that “the immunosuppression of traditional therapies is too broad: The time to benefit is too long, the burden of side effects is too high, and the cancer risk is too elevated.”
Traditional Therapy: Affordable, Tolerable, and Safe?
Claytor said ideal myasthenia gravis therapies are effective, tolerable, and safe. They’re also affordable, convenient (such as a pill), lead to sustained remission, and can have dosages reduced.
Only traditional therapies — corticosteroids, azathioprine, mycophenolate, and rituximab — meet those last three criteria, he said. Newer therapies, he said, do not.
Claytor highlighted a 2023 Duke University study that tracked 367 patients with MG who were treated with traditional therapies after the year 2000. Of those, 72% reached the treatment goal of minimal manifestations in a median of less than 2 years.
In addition, Claytor noted that the percentage of patients with myasthenia gravis who reach minimal symptom expression ranges from 45% (6 months) to 60% or more (2 years), while studies suggest that newer treatments such as eculizumab (Soliris), efgartigimod (Vyvgart), rozanolixizumab (Rystiggo), and zilucoplan (Zilbrysq) haven’t reached those levels.
As for specific traditional therapies, Claytor said the corticosteroid prednisone is “extremely affordable,” effective, and takes fewer than 2 weeks to work. All patients with myasthenia gravis can take it, he said, and at least 75% of those with mild/moderate disease respond to low doses.
Nonsteroidal Agents, Immune Globulin, Rituximab
He acknowledged side effects from corticosteroids but said doses can be tapered once severity improves. Calcium and vitamin D can be helpful to support bone health, he added.
As for nonsteroidal immunosuppressive treatments, he said they’re easy to administer, increase the likelihood of reaching minimal manifestation status, can be effective at lower doses, and may allow patients to discontinue steroids.
Two other traditional therapies, immune globulin and plasmapheresis, can be appropriate in crisis or impending crisis situations, he said, or as an add-on therapy if steroids and nonsteroidal immunosuppressive therapies don’t work.
What about rituximab? “We’re learning that patients with new-onset disease and younger patients seem to respond better,” Claytor said. While rituximab is expensive, it’s “not even in the same realm” as newer agents if only a dose or two are given, he said.
Steroids Are Ideal in MG? Not So Fast
In her response, Guidon noted that she was assigned to offer a counter-perspective in her presentation, and “personal opinions are not being represented here fully.” She then listed the weaknesses of traditional therapy in myasthenia gravis.
For one thing, she said the drugs don’t work well. She highlighted a 2019 registry study that found “many myasthenia gravis patients remain negatively impacted despite treatment.”
In addition, “we can’t predict who will respond to which therapy. ... We start drugs and don’t know if we’ll have benefit from 6 months up to 18 months. We also can’t determine minimally effective dose a priori. Some patients require higher doses, and some subtherapeutic doses are actually therapeutic for our patients.”
Broad immunosuppression, she added, boosts the risk for serious infections. “We’ve all heard from our patients that the side effects can be worse than the myasthenia, and next we’re going to talk about the role of corticosteroids in myasthenia.”
As for corticosteroids in particular, “they’re really the best treatment and also the worst treatment.” Efficacy and side effects battle for supremacy in patients, she said, “and you don’t know which is going to win out.”
Kicking Traditional Therapy to the Curb
There are many possible side effects from steroids, she said, including steroid-induced diabetes, which is “profound.” Some patients never recover from it.
On top of all these risks, she said, 20%-30% of patients are resistant to steroids.
As for other treatments, immune globulin and plasmapheresis “aren’t really benign,” Guidon said. They come with potentially serious side effects of their own, as do nonsteroidal immunosuppressive treatments.
Guidon said better treatments are needed to minimize the risks from traditional therapies. “We need targeted therapies that drive disease into remission, can be tapered, are delivered orally or with infrequent self-injections, and don’t require frequent lab monitoring.”
In addition, ideal treatments should “have a good safety data in pregnancy and for breastfeeding and have a favorable side effect profile with no significant long-term cancer risks.”
Claytor had no disclosures. Guidon disclosed consulting/medical advisory board (Alexion Pharmaceuticals, argenx, Regeneron, and UCB), publishing royalties (Oakstone), and other research support (Myasthenia Gravis Foundation of America, Myasthenia Gravis Rare Disease Network, National Institutes of Health, and National Institute of Neurological Disorders and Stroke/BioSensics).

As for corticosteroids in particular, “they’re really the best treatment and also the worst treatment.” Efficacy and side effects battle for supremacy in patients, she said, “and you don’t know which is going to win out.”
Kicking Traditional Therapy to the Curb
There are many possible side effects from steroids, she said, including steroid-induced diabetes, which is “profound.” Some patients never recover from it.
On top of all these risks, she said, 20%-30% of patients are resistant to steroids.
As for other treatments, immune globulin and plasmapheresis “aren’t really benign,” Guidon said. They come with potentially serious side effects of their own, as do nonsteroidal immunosuppressive treatments.
Guidon said better treatments are needed to minimize the risks from traditional therapies. “We need targeted therapies that drive disease into remission, can be tapered, are delivered orally or with infrequent self-injections, and don’t require frequent lab monitoring.”
In addition, ideal treatments should “have a good safety data in pregnancy and for breastfeeding and have a favorable side effect profile with no significant long-term cancer risks.”
Claytor had no disclosures. Guidon disclosed consulting/medical advisory board (Alexion Pharmaceuticals, argenx, Regeneron, and UCB), publishing royalties (Oakstone), and other research support (Myasthenia Gravis Foundation of America, Myasthenia Gravis Rare Disease Network, National Institutes of Health, and National Institute of Neurological Disorders and Stroke/BioSensics).

New Drug Options Abound for Duchenne Muscular Dystrophy
SAVANNAH, GEORGIA — When Ann & Robert H. Lurie Children’s Hospital of Chicago pediatric neurologist Nancy L. Kuntz, MD, was a fellow about 45 years ago, there were few more devastating diagnoses than Duchenne muscular dystrophy (DMD).
“The rule of thumb was that they would stop walking by age 10 and probably die around age 20, and there was not much we could do,” Kuntz told colleagues at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024.
Now, “In the last 8 years, we’ve seen eight different therapies that are FDA-approved specifically for Duchenne, and many more are in the pipeline,” said session moderator Kathryn Mosher, MD, a pediatric physical medicine and rehabilitation physician at Akron Children’s Hospital, Akron, Ohio.
This is both good news and a new challenge for clinicians: Which of these treatments are best for which patients? Kuntz said the traditional therapy of corticosteroids is still crucial. However, “there are still families begging to not use steroids, or refusing to use steroids, just not filling the prescriptions,” she said.
Beware of Parents Who Reject Steroids
The failure to use steroids “breaks your heart” because data show their impact on “really important functions like walking and being able to get up from the ground,” she said. “You can add months and years to life with this treatment.”
However, “while we have shown that using corticosteroids makes a difference, I don’t think that we’ve really worked out the best age at which to start the steroids, or the dosing schedule, or even the type of steroids,” she cautioned.
In an accompanying presentation about therapy for DMD, pediatric neurologist Craig M. Zaidman, MD, of Washington University in St. Louis, Missouri, cautioned that “daily steroids make a big impact on your growth and particularly on your height.”
In particular, the corticosteroid deflazacort has been linked to more cataracts than prednisone and less weight gain and height growth. “They really don’t grow, they don’t get taller, and they also don’t gain weight. They look like little boys when they’re 13 years old.”
Deflazacort or Vamorolone?
Vamorolone (Agamree) is a cheaper corticosteroid alternative to deflazacort (Emflaza), and a 2024 study showed no difference in functional outcomes over 48 weeks, he said. Also, daily vamorolone does a better job of preserving height growth than daily prednisone, he said, and he’s seen less risk for vertebral fractures.
Where do newer drugs fit in? One crucial thing to know about the new generation of targeted therapies is that they’re often mutation-dependent, Kuntz said. They may only work in patients with certain mutations, or mutations may lead to more side effects.
“You should have the exact mutation of your patient, and then you can look and see what they’re eligible for,” she said.
$700,000 a Year for Givinostat
Zaidman highlighted the newly approved givinostat (Duvyzat), a histone deacetylase inhibitor approved for boys 6 years or older. The cost is $700,000 a year, he said, and it’s been linked to less decline in four-stair climb per a double-blind, placebo-controlled, phase 3 trial.
The drug can cause side effects such as reducing platelets, boosting triglycerides, and inducing gastrointestinal problems. “When you drop the dose, these problems go away,” he said.
Does givinostat work? While trial data are challenging to interpret, they do suggest that patients “will lose skill, but they might not lose two or three skills they otherwise would have,” Zaidman said. “To me, that’s quite compelling.”
As for exon-skipping therapies, another new-generation option for DMD, he noted that “these drugs are on the market based on their accelerated approval. We will never have the perfect phase 3, randomized, controlled, long-term trial for these. It’s just not going to come. This is what we get.”
Mosher disclosed the advisory board (Sarepta Therapeutics, Pfizer, Reata Pharmaceuticals, and PTC). Kuntz disclosed advisory board (Astellas Pharma, Inc., argenx, Catalyst, Entrada Therapeutics, Genentech, and Novartis), exchange expert on-demand program (Sarepta Therapeutics), speaker (Genentech, Sarepta Therapeutics, and Solid), and research funding (Astellas Pharma, Inc., argenx, Biogen, Catalyst, Genentech, Novartis, and Sarepta Therapeutics). Zaidman disclosed speaking/advisor/consulting (Sarepta Therapeutics and Optum) and research funding (Novartis and Biogen).

FROM AANEM 2024
JIA Treatment Has Increasingly Involved New DMARDs Since 2001
TOPLINE:
The use of newer biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) for treating juvenile idiopathic arthritis (JIA) rose sharply from 2001 to 2022, while the use of conventional synthetic DMARDs (csDMARDs) plummeted, with adalimumab becoming the most commonly used b/tsDMARD.
METHODOLOGY:
- Researchers performed a serial cross-sectional study using Merative MarketScan Commercial Claims and Encounters data from 2000 to 2022 to describe recent trends in DMARD use for children with JIA in the United States.
- They identified 20,258 new episodes of DMARD use among 13,696 children with JIA (median age, 14 years; 67.5% girls) who newly initiated at least one DMARD.
- Participants were required to have ≥ 365 days of continuous healthcare and pharmacy eligibility prior to the index date, defined as the date of DMARD initiation.
TAKEAWAY:
- The use of csDMARDs declined from 89.5% to 43.2% between 2001 and 2022 (P < .001 for trend), whereas the use of bDMARDs increased from 10.5% to 50.0% over the same period (P < .001).
- Methotrexate was the most commonly used DMARD throughout the study period ; however, as with other csDMARDs, its use declined from 42.1% in 2001 to 21.5% in 2022 (P < .001 ).
- Use of the tumor necrosis factor inhibitor adalimumab doubled from 7% in 2007 to 14% in 2008 and increased further up to 20.5% by 2022; adalimumab also became the most predominantly used b/tsDMARD after csDMARD monotherapy, accounting for 77.8% of prescriptions following csDMARDs in 2022.
- Even though the use of individual TNF inhibitors increased, their overall popularity fell in recent years as the use of newer b/tsDMARDs, such as ustekinumab and secukinumab, increased.
IN PRACTICE:
“These real-world treatment patterns give us insight into how selection of therapies for JIA has evolved with increasing availability of effective agents and help prepare for future studies on comparative DMARD safety and effectiveness,” the authors wrote.
SOURCE:
The study was led by Priyanka Yalamanchili, PharmD, MS, Center for Pharmacoepidemiology and Treatment Science, Institute for Health, Rutgers University, New Brunswick, New Jersey, and was published online October 22, 2024, in Arthritis & Rheumatology.
LIMITATIONS:
The dependence on commercial claims data may have limited the generalizability of the findings to other populations, such as those with public insurance or without insurance. The study did not have access to demographic data of the participants to investigate the presence of disparities in the use of DMARDs. Moreover, the lack of clinical details about the patients with JIA, including disease severity and specialty of prescribers, may have affected the interpretation of the results.
DISCLOSURES:
The study was supported by funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and several other institutes of the National Institutes of Health, as well as the Rheumatology Research Foundation and the Juvenile Diabetes Research Foundation. No conflicts of interest were reported by the authors.

No Benefit to High-Dose IV Vs Oral Steroids in Giant Cell Arteritis
TOPLINE:
In patients with giant cell arteritis (GCA), intravenous methylprednisolone compared with oral glucocorticoids alone does not improve visual acuity and increases the risk for diabetes within the first year. Survival rates do not differ with these two treatments.
METHODOLOGY:
- Researchers conducted a population-based retrospective study at three centers in Sweden to assess the clinical characteristics, treatment-related toxicity, and mortality in patients with GCA who were receiving high-dose intravenous methylprednisolone.
- A total of 419 patients with biopsy-confirmed GCA (mean age at diagnosis, 75 years; 69% women) diagnosed from 2004 to 2019 were included.
- Patients were treated with either intravenous methylprednisolone (n = 111) at a dose of 500-1000 mg per day for 3 consecutive days or oral glucocorticoids alone (n = 308).
- Ischemic visual complications considered to indicate visual involvement were confirmed by an ophthalmologist, and data on visual acuity were collected from ophthalmologic clinic records at initial consultations and follow-up at 3-18 months.
TAKEAWAY:
- Despite a tendency toward improvement, no significant difference in visual acuity was observed with intravenous methylprednisolone compared with oral glucocorticoids.
- Patients treated with intravenous methylprednisolone had a higher risk for newly diagnosed diabetes within a year of GCA diagnosis (odds ratio [OR], 2.59; P = .01).
- The risk for diabetes remained elevated even after adjustment for the cumulative oral glucocorticoid dose at 3 months (adjusted OR, 3.30; P = .01).
- Survival rates did not significantly differ between the treatment groups over a mean follow-up of 6.6 years.
IN PRACTICE:
“In this study on the use of intravenous methylprednisolone treatment in GCA, we found no evidence of a beneficial effect in improving visual acuity or enabling more rapid tapering of the oral glucocorticoid dose,” the authors wrote. “The use of IVMP [intravenous methylprednisolone] was associated with an increased risk of diabetes during the first year compared with oral GC [glucocorticoid], raising questions about the value of IVMP in GCA treatment.”
SOURCE:
The study, led by Hampus Henningson, Department of Clinical Sciences, Rheumatology, Lund University, Lund, Sweden, was published online in Rheumatology.
LIMITATIONS:
The retrospective nature of the study may have resulted in missing data and difficulty in accurately quantifying the cumulative glucocorticoid doses. The study did not validate the diagnoses of comorbidities but relied solely on diagnostic codes.
DISCLOSURES:
This study was supported by the Swedish Research Council, Swedish Rheumatism Association, Swedish Medical Society, Alfred Österlund’s Foundation, and King Gustaf V’s 80-year foundation. The authors declared no conflicts of interest.

Neurologists Lack Awareness of Steroid Toxicity
SAVANNAH, GEORGIA — , results of a US survey showed.
For both MG and CIDP specialists, uncertainty around corticosteroid dosing, duration, and toxicity underscores the need for more guidance, the investigators noted. Over 85% of respondents indicated that a tool for systematically monitoring corticosteroid toxicity would be valuable.
The results indicate “a lack of knowledge by this pool of neurologists about the guidelines and what they contain,” said study investigator Gil Wolfe, MD, professor of neurology at the Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, in New York.
Clearer guidance on how to administer corticosteroids and manage toxicities in patients with gMG and CIDP “would be welcomed by neurologists and have potential for benefit to patient care,” the team noted.
The findings were presented at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024.
Lack of Knowledge
Although guidelines for both CIDP and gMG recommend corticosteroids as first-line treatment and emphasize using the lowest effective dose to control symptoms, they do not include specific recommendations on dosing, duration, or toxicity monitoring, the researchers noted.
Despite this, a large proportion of survey respondents reported using guidelines to make clinical decisions on monitoring toxicity, with up to a third actually endorsing a guideline that doesn’t exist.
The cross-sectional, online survey was deployed in November and December 2023 and included 200 US neurologists. Of these, 99 answered questions on CIDP, and 101 answered similar questions on gMG.
To participate in the survey, respondents had to be board-certified neurologists, practicing for at least 2 years post-residency, and have treated or consulted on at least three patients with CIDP or 10 patients with gMG in the past year who were on a corticosteroid dose of at least 10 mg daily for 1 month or more.
CIDP respondents had been practicing a mean of 18.1 years since residency and were board certified in neuromuscular (20%), electrodiagnostic medicine/clinical neurophysiology (21%), and pediatric neurology (8%). Two thirds of them accepted referrals from other neurologists.
The gMG respondents had been practicing a mean of 20.5 years since residency and were board certified in neuromuscular (45%), electrodiagnostic medicine/clinical neurophysiology (35%), and pediatric neurology (17%). A total of 72% accepted referrals from other neurologists.
Respondents estimated that about 60% of their patients with gMG and 58% of patients with CIDP were being treated with corticosteroids, with gMG and CIDP respondents reporting a mean of 26.4 and 15.6 patients, respectively, meeting the study’s dosing criteria.
Appropriate Dosing
When asked what chronic, long-term (≥ 6 months) corticosteroid dose they considered safe in terms of minimizing adverse events, 43% of CIDP respondents and 51% of gMG respondents considered corticosteroid doses of 10 mg/d or less (prednisone equivalent) well tolerated; additionally, 32% and 31%, respectively, considered 20-40 mg/d well tolerated. Moreover, they said only about half of their patients would be able to taper to less than 10 mg/d in less than 6 months.
“Studies suggest safety is not seen until patients are on doses at 5 mg/d or less,” Wolfe said. “There is not enough appreciation that doses at levels we once considered safe really do pose significant risk,” he added.
“With the increasing number of treatment options in MG and to a lesser extent in CIDP, we need to do all we can to use corticosteroids as judiciously as possible and be aware of side effects our patients may not even report unless we make a pointed effort to ask about them.”
Familiarity with corticosteroid toxicities was more common among gMG respondents, of whom 77% reported being very/extremely familiar, than among 55% of CIDP respondents. Appetite/weight gain was reported among the most common adverse effects (AEs) associated with long-term CS use (reported by 68% of CIDP and 58% of gMG respondents). Other common AEs reported were insulin resistance (53% of CIDP and 50% of gMG respondents), decreased bone density (47% and 48%, respectively), immunosuppression (37% and 45%, respectively). Mood and behavioral change were noted by 56% of CIDP and 37% of gMG respondents, particularly mood swings, irritability, mania, and sleep disorders.
When asked how they balanced the risk for and benefit of corticosteroids, more than 80% of CIDP specialists reported personally monitoring for corticosteroid-related toxicity, and 42% reported they collaborated with the patient’s primary care provider. However, fewer than 10% reported ordering lab tests. Among neurologists treating gMG, 84% said they typically monitor corticosteroid toxicity independently, while 41% reported doing so in collaboration with primary care providers.
Two thirds of CIDP respondents and 53% of gMG respondents reported using guidelines to make clinical decisions on monitoring toxicity, and 34% of gMG respondents actually endorsed using the Guideline for Systematic Surveillance of Steroid Safety, which does not exist.
‘A Big Issue’ in Neurology
Commenting on the results, Said R. Beydoun, MD, professor and division chief, Neuromuscular Medicine, Department of Neurology at Keck Medicine of University of Southern California, Los Angeles, said steroid toxicity is “a big issue” in neurology.
These patients can be on chronic therapy, and they aren’t really monitored for osteoporosis or other complications, he said, adding that neurologists aren’t always taking the necessary precautions to prevent steroid toxicity.
Beydoun estimated that about half of neurologists are not adequately familiar with balancing the efficacy of corticosteroids versus in toxicity.
“Objective improvement, either on the functional scale or the muscle impairment scale — that’s really response treatment. Whereas adverse effects of a treatment are something separate. The patient may be improving but also maybe developing other complications from the treatment,” he said.
Also commenting, Ghazala Hayat, MD, professor of neurology and director of neuromuscular and clinical neurophysiology services at Saint Louis University in St. Louis, said there is a clear need for more education.
“I always say prednisone is our best friend initially, and then it becomes the worst enemy. If you don’t see lots of neuromuscular patients, you might not know even how to recognize toxicity or how to taper. Or the opposite to that, if you taper too quickly, patients relapse.”

Neelam Goyal, MD, is a consultant/advisor for Alexion, argenx, Amgen, Janssen, Lycia Therapeutics, and UCB and has received grant support from argenx.

Veterans Affairs Hailed as a ‘Bright Spot’ in ALS Care
SAVANNAH, GEORGIA — , said one expert.
In a plenary address at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024, Ileana Howard, MD, medical co-director of the ALS Center of Excellence at VA Puget Sound in Seattle, said the recently released National Academies report “Living with ALS” cited the Veterans Administration as “a bright spot in the landscape of ALS care due to its interdisciplinary, holistic, and proactive approach to care.”
Since the early 2000s and the publication of several studies linking active military service with ALS, the US Department of Veterans Affairs (VA) has opened an ALS registry, a tissue and brain biobank, and in 2008, granted 100% presumptive service connection to any individual who served more than 90 days of active duty and was later diagnosed with ALS, she said.
“We now serve approximately 4000 veterans with ALS across the system, and we count 47 full interdisciplinary clinics within VA across the nation, with ALS coordinators designated for all 170 VA facilities, regardless of whether they had an ALS clinic or not, to serve as a navigator for patients and their families, to identify the closest ALS clinic that could meet their needs.”
Multidisciplinary vs Interdisciplinary
Howard emphasized that transdisciplinary collaboration is essential for maintaining an effective system. She pointed out that the term “multidisciplinary” is outdated, referring to teams that work independently but in parallel on the same issue.
In contrast, interdisciplinary teams integrate their assessments into a cohesive plan of care, whereas transdisciplinary teams take it further by combining both their assessments and care plans, allowing for greater intentional overlap.
The VA’s ALS handbook lists approximately 20 essential clinicians for a VA ALS clinic, including recreation therapists, assistive technology specialists, and veteran benefit service officers to assist with disability benefits application, among others, she said.
Essential to this collaboration is “role release,” which deliberately blurs the boundaries between disciplines. “The future of our specialty hinges on effective and selfless collaboration,” she said.
Howard encouraged ALS healthcare providers to move away from outdated terminology rooted in hierarchical team models and to break down silos that no longer benefit either the patients or the care teams.
She noted that while teamwork can enhance patient outcomes and overall health, it has also been associated with better health among healthcare providers. It’s well-known, she said, that neurologists and physiatrists are among the specialties with the highest burnout rates, and ALS teams, in particular, experience significant stress and burnout.
Better Together
A recent Canadian study on resiliency and burnout in ALS clinics surveyed a wide range of practitioners within ALS centers and found respondents drew resiliency through relationships with patients and colleagues, and that there was a strongly expressed desire for increased resources, team building/debriefing, and formal training in emotional exhaustion and burnout.
“A consistent theme was the lack of adequate allied health support (nursing, social work, occupational therapy) to address the complex needs of patients,” said the report’s senior author Kerri Lynn Schellenberg, MD, medical director of the ALS/Motor Neuron Diseases clinic and associate professor at the University of Saskatchewan College of Medicine in Saskatoon, Saskatchewan, Canada.
“The majority of participants felt they would benefit from more consistent team building exercises and debriefing,” noted the authors.
Schellenberg agreed, emphasizing that care teams perform best when there is mutual appreciation and support among members. By learning from one another and reaching consensus together, the care plan benefits from the collective expertise of the team. “We are stronger together,” she said.
Howard and Schellenberg reported no disclosures.
