treatment

When the U.S. Food and Drug Administration approved the disease-modifying therapy Mayzent for relapsing types of multiple sclerosis, it specified in its label that the treatment was for people with clinically isolated syndrome, relapsing-remitting MS, and — importantly — secondary progressive MS provided they have "active" disease. The approval is good news, an MS researcher and physician said to Multiple Sclerosis News Today in an interview, but "surprising" in that the FDA's decision was largely based on a trial that didn't involve CIS patients and wasn't focused on responses among particular types of SPMS. “It's the first time that I've seen in the MS field that regulators made an approval designation — active secondary progressive MS — based on an underpowered subgroup analysis,” said Robert Fox, MD, a neurologist at the Mellen Center for Multiple Sclerosis at the Cleveland Clinic. Novartis' medication, as a first oral therapy approved in the U.S. for a form of SPMS, is a big step forward in MS treatment, he said. But details of the FDA's decision caught him off guard. Fox served on the steering committee for the EXPAND Phase 3 clinical trial , on which the FDA decision was largely based. His clinic was also one of the sites treating and evaluating patients in this pivotal study. Results of the EXPAND trial showed that Mayzent could reduce the risk of disability progression at three months (the trial’s primary endpoint, or goal) by 21% in treated SPMS patients, compared to those given a placebo. Among those with active SPMS (meaning with relapses), a 33% reduction was observed. The treatment, an S1P modulator that works in part to keep lymphocytes from entering the brain to trigger inflammation, also decreased the annualized relapse rate by 55% and improved cognitive processing speed in all treated patients.  “What was found, and I think quite clearly found in a large-size study, was that siponimod in patients with secondary progressive MS clearly slowed the progression of clinical disability over the course of the trial,” Fox said. “It's a statistical concept — obviously patients either progress or they don't progress — but on an overall basis there was a 21% slowing in the rate of progression of clinical disability.” The FDA’s decision is particularly important for SPMS patients. While Ocrevus (ocrelizumab) also treats all relapsing MS forms and people with primary progressive disease (PPMS), it's an intravenous therapy given every six months. Mavenclad (cladribine), approved for relapsing patients in the U.S. just days after Mayzent, is another oral and active disease therapy. To Fox, Mayzent seemed to reach beyond only those secondary progressive patients with clinically active disease. “Really, this is the only drug that's been found to be effective in secondary progressive MS," he said. “To that degree, it stands alone.” That's why two points in the FDA's decision surprised him. The first is the label's specific mention of clinically isolated syndrome. CIS is defined as the first clinical presentation of this disease — a neurological episode that lasts at least 24 hours, and is characterized by inflammatory demyelination (the loss of myelin, the protective coat surrounding neurons).   For clinicians like Fox, CIS is a first manifestation of MS — a kind of "mono sclerosis." Since there’s only one documented attack, it can’t yet be considered multiple sclerosis, “as the multiple hasn't happened,” Fox said, but many "in the field consider CIS to be … an early stage of MS." “If the patient has a whole bunch of lesions on their brain [as seen on an MRI scan] and they had a single clinical event, ah, probably, they have MS,” he said. Regulatory bodies like the FDA, however, have historically considered CIS to be its own separate entity. That makes this decision doubly surprising, according to Fox, since the EXPAND trial only enrolled patients with SPMS, not CIS.   “It's the first time I've seen them approve for CIS specifically when there wasn't a trial in CIS,” Fox said. “I agree with it — I don't have a problem with it — it just surprised me that the regulators were so progressive in their appreciation of MS.” The second — and far more unsettling — surprise was the FDA’s decision to only approve Mayzent for “active” SPMS patients, instead of all SPMS patients. This decision didn’t come out of nowhere, he noted, but it remains puzzling in the context of the EXPAND trial.  In compiling trial results, investigators did a subgroup analysis — as they often do, almost as an aside for research reasons — and found more favorable responses to Mayzent treatment in patients with active inflammation before the trial's start, those it determined to be with "active" disease.   “There was a third of patients who had a relapse in the two years prior to enrollment, and those patients actually had a 30% slowing in disability progression, compared to the 21% overall,” Fox said. This certainly does suggest that Mayzent can be more effective in people with active disease — but there's a catch. The trial itself was not designed to make such a distinction. It enrolled SPMS patients regardless of activity, and its priority goal was changes in disease progression across all who were treated with Mayzent or given a placebo.   “What's important is that the trial was powered for the overall outcome. It was not powered for subgroup analysis,” Fox said, considering this a crucial point.  In clinical studies, being “powered” refers to the enrolling of whatever specific number of participants a study needs to ensure its results will reach statistical significance. More people are redundant and, as such, an unnecessary cost; fewer could mean that trial's conclusions cannot be supported by rigorous scientific measures.  In other words, Fox said, the only conclusions that can be drawn from the EXPAND study reliably — with rigor — are based on data drawn from all its SPMS patients, not a subgroup with active disease. This trial “followed over 1,600 patients for the clinical disability. These are purposely powered so that you're not following twice as many people as you need to … you're powered for that primary outcome,” he said. “So, how could they [the FDA] look at a subgroup analysis and make an approval decision based on a subgroup analysis that was underpowered?” The neurologist gave as examples other subgroup differences found in trial analyses that didn't affect regulatory approval — but to his mind, equally could have. One was an analysis finding female SPMS patients responded to the therapy better than males, showing lesser disease progression. "So why didn't they just approve it for the females and not the males?" Fox asked. But, when asked, Fox did not think the label to necessarily be an error. "My point is the absurdity of it," he said. "How could they make the regulatory approval based on a subgroup analysis that wasn't powered for conclusions?" He was also particularly troubled because the FDA “didn't define what ‘active’ means — is it just a relapse, or is it MRI disease activity?"  For many clinicians, “active” SPMS refers to ongoing inflammation that can be observed on MRI (magnetic resonance imaging) scans. In EXPAND, however, the active subgroup was defined as patients with clinical relapses within two years of being enrolled in the trial. Fox worries about this apparent lack of a regulatory definition of "active" SPMS, since “obviously, the insurance companies are going to seize upon that, and they're going to look for every way they can to avoid covering it for patients.” Mayzent, Fox agreed, is likely to be expensive. The therapy is reported to carry a U.S. list price of $88,500 a year. “I always have a concern about the cost of these drugs. They're all fearfully expensive,” he said, noting he treats SPMS patients. His focus now is on working to ensure that possible regulatory and financial hurdles won’t pose too much of an obstacle for patients, especially those with SPMS. “I don't know what the insurance companies are going to do with this, but I'm hoping that it is available for my patients, and I say that as their clinician,” Fox concluded.

An application has been submitted to approve ozanimod as an oral treatment for adults with relapsing forms of multiple sclerosis in the U.S., according to its developer, Celgene. “New oral treatment options with differentiated profiles like ozanimod are needed to help address an unmet need for people with relapsing forms of MS,” Jay Backstrom, MD, Celgene’s chief medical officer, said in a press release. Celgene's New Drug Application has been submitted to the U.S. Food and Drug Administration. Earlier this month, the company submitted a marketing authorization application to the European Medicines Agency covering the treatment of adults with relapsing-remitting MS. “With concurrent applications in the U.S. and EU, we look forward to advancing this promising medicine through the regulatory review process to provide a new option for the treatment of (relapsing MS) in 2020,” Backstrom said. Ozanimod is designed to cause the retention of immune cells in lymphoid tissues, thereby blocking their migration to the central nervous system — brain and spinal cord — and preventing damage to nerve fibers and their protective layer, called myelin. The investigational therapy selectively binds to S1P receptor subtypes S1P1 and S1P5. The NDA application is based on positive findings from two multicenter, double-blind, Phase 3 trials called SUNBEAM and RADIANCE part B. Both studies demonstrated that ozanimod reduced the number of relapses and brain lesions. In the SUNBEAM Phase 3 trial, 1,346 participants with relapsing MS were randomized to one daily dose of 0.92 or 0.46 mg of ozanimod — equivalent to 1 mg and 0.5 mg of the therapy’s HCI formulation — or Avonex (interferon beta-1a, marketed by Biogen) for at least 12 months. Results showed that treatment with ozanimod led to fewer relapses and brain lesions, as well as clinically meaningful improvements in processing speed compared with Avonex. In the Phase 2/3 RADIANCE trial, patients were divided in two parts: in part A, participants received either one daily dose of ozanimod (0.5 mg or 1.0 mg) or a placebo for 24 weeks; in part B, a 96-week open-label extension study completed by 223 patients, those initially on placebo switched to ozanimod. As in the SUNBEAM trial, results of part A of the RADIANCE trial revealed a reduction in the number of brain lesions from weeks 12 to 24, as well as less frequent relapses compared with a placebo. Treatment with ozanimod was safe and well-tolerated. Findings of part B of the study included an increased percentage of patients free of T1 lesions on MRI (magnetic resonance imaging) scans — which refer to areas of active inflammation and disease activity — after two years of treatment, from 58.5–69.0% of patients in part A to 86.5–94.6% of patients in part B. T2 lesions, a measure of the total amount of MRI lesions — both old and new — and relapse rate remained low in patients maintained on ozanimod (more significantly with the higher dose of 1.0 mg), and dropped in those who switched from a placebo. The scientists also analyzed ozanimod’s benefits using data from the SUNBEAM and RADIANCE part B trials, which covered 2,659 patients treated over one to two years. Compared with Avonex, ozanimod reduced the annualized relapse rates — the number of relapses per year — by 42% in the higher dose group and 26% in the lower dose group. Treatment with ozanimod also lessened the relapse rate requiring steroid treatment or hospitalization by 43% (in the 1 mg dose group) and 26% (in the 0.5 mg dose group) compared with Avonex treatment. In addition to MS, ozanimod is also being developed for patients with ulcerative colitis and Crohn's disease, two inflammatory bowel diseases.

Treatment with ublituximab continues to be safe and well-tolerated by patients with relapsing forms of multiple sclerosis, according to an extension study of a Phase 2 trial. According to a press release, Edward Fox, MD, PhD, from Central Texas Neurology Consultants, will give the presentation on May 7 at poster session P3: MS Clinical Trials and Therapeutic Research. Ublituximab is an investigational monoclonal antibody being developed by TG Therapeutics to target the immune B-cell marker protein CD20. This leads to the depletion of B-cells from the blood and central nervous system — B-cells are activated during MS relapses. According to the company, ublituximab may be superior to current anti-CD20 treatments in MS, enabling both lower doses and shorter infusion times. Final results of the main TG-Therapeutics-sponsored Phase 2 trial were recently presented at the 4th Annual Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum, held in Dallas, Texas. Data showed that 93% of the 48 patients enrolled (mean age 40 years) were relapse-free after a 48-week treatment with ublituximab. The annualized relapse rate — the number of relapses per year — was 0.07. In addition, median B-cell depletion was more than 99% throughout 48 weeks. Moreover, 87% of participants showed no evidence of clinical disease. Magnetic resonance imaging showed a complete elimination of T1 lesions at 24 and 48 weeks 24 in all 46 patients analyzed. Mean T2 lesion volume decreased by 10.6% at 48 weeks, compared with the beginning of the study. T1 lesions refer to areas of active inflammation and disease activity, while T2 lesions are a measure of the total amount of lesions, both old and new. Ublituximab was found to be well-tolerated, and did not induce an severe treatment-related adverse events. The most frequent adverse events were infusion-related reactions. No patient had to discontinue treatment due to an ublituximab-related side effect. At the upcoming AAN meeting, Fox will present data on both this Phase 2 trial and its open-label extension, in which 37 patients from the primary study continued receiving one-hour infusions of 450 mg of ublituximab every 24 weeks for an additional 96 weeks. Safety was monitored throughout the study, and disability assessments using the Expanded Disability Status Scale were conducted every 48 weeks. As of October 2018, nearly 30% of participants had completed 48 weeks of treatment in the extension study. Results showed that ublituximab continues to be well-tolerated, with no discontinuations due to adverse events. “The Phase 2 OLE supports that one-hour infusions of [ublituximab] continue to be safe and well tolerated,” the researchers wrote. Of note, five of the eight study authors are affiliated with TG Therapeutics. The team expects additional patient follow-up data from the study to be available by the time of the AAN presentation. According to the scientists, the results support the ongoing Phase 3 ULTIMATE program, which includes the ULTIMATE 1 and ULTIMATE 2 trials. These studies are comparing the efficacy and safety of 450 mg of ublituximab with Aubagio over 96 weeks of treatment in relapsing MS patients. Both trials are led by Lawrence Steinman, MD, at Stanford University. TG Therapeutics expects to have results from these trials as early as mid-2020.

Treating multiple sclerosis with Tecfidera induces specific genetic alterations that may reduce the levels of immune T-cells targeting the central nervous system, researchers report. Environmental stimuli may induce epigenetic changes in cells — meaning not alterations in the genes themselves, but changes in gene expression (the process by which information in a gene is synthesized to create a working product, like a protein). Epigenetic changes may induce MS development, as these alterations can cause T-cells to attack the central nervous system. One type of epigenetic change is DNA demethylation, the removal of methyl chemical groups, in which molecules involved in metabolism (such as fumarate) interact with enzymes known as DNA demethylases. This process in key for T-cell activation, function and memory, suggesting that it could be an immunomodulatory target. Fumaric acid esters were shown to be effective in MS clinical trials, leading to the approval of Tecfidera (by Biogen) for people with relapsing-remitting forms of the disease. However, their complete mechanism of action remains unclear. Aiming to address this gap, scientists at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York and the Icahn School of Medicine at Mount Sinai, recruited 98 MS patients, either previously untreated (47 people, mean age of 38.4), treated with Tecfidera (35 people, mean age of 42.3), or treated with glatiramer acetate (16 patients, mean age of 43.4) — marketed as Copaxone by Teva Pharmaceuticals, with generic forms by Sandoz (as Glatopa) and by Mylan. All patients had stable disease for at least three months, but disease duration was shortest in untreated patients — 40.4 months vs. 130 months in those given Tecfidera, and 100 months in patients using glatiramer acetate. Blood samples were collected from each participant to assess epigenetic changes in T-cells expressing the cell surface marker CD4. MS patients typically have an activated form of these cells in their blood and cerebrospinal fluid, the liquid surrounding the brain and spinal cord. Results revealed that, compared to the other two groups, treatment with Tecfidera was associated with a lower percentage of T-cells containing the CD3, CD4, and CD8 markers, as well as lower levels of subsets of T-cells expressing the CCR4 and CCR6 receptors, which are critical to T-cell migration to the gut, brain, and skin. Treatment with glatiramer acetate resulted in significantly milder alterations in T-cell percentages compared to no treatment. Researchers then found that FAEs induce excessive methylation — the addition of methyl groups — in T-cells containing CD4, compared to glatiramer acetate. Specifically, this overmethylation was observed in a micro-RNA — tiny RNA molecules than control gene expression — known as miR-21, key for the differentiation of a subset of T-cells called T helper-17 (Th17) cells and for CCR6 expression in MS mouse models. These Th17 cells are critical in tissue inflammation and destruction, and have been implicated in MS. The epigenetic effects of FAEs were subsequently validated by comparing pre- to post-treatment with Tecfidera in seven patients. In turn, in vitro (lab dish) experiments showed that FAEs act specifically on the activation of naïve T-cells — those able to respond to new pathogens to the immune system — containing the CD4 or the CD8 markers. Of note, patients with MS have shown increased miR-21 levels, particularly during acute relapses. As such, the team hypothesized that its hypermethylation by FAEs could contribute to remission and the prevention of relapses in this patient population. These results "suggest that the metabolic-epigenetic interplay in T-cells could be harnessed for therapeutic purposes," the researchers wrote, and that the immunomodulatory effect of FAEs in MS is due at least in part to the epigenetic regulation of T-cells. The researchers believe that their findings have a broader implication, beyond MS. "Our findings about therapeutically active metabolites have implications for the treatment of not only multiple sclerosis but also other autoimmune diseases, such as psoriasis and inflammatory bowel disease, which involve the same type of T-cells," Achilles Ntranos, the study’s lead author, said in a press release. "Understanding the epigenetic effect of metabolites on the immune system will help us develop several novel strategies for the treatment of autoimmune diseases, which could help patients and physicians achieve better clinical outcomes," Ntranos added. Patrizia Casaccia, the study’s senior author, concluded: "It may one day be possible to target and suppress production of the specific brain-homing T-cells that play a role in the development of MS."
