RRMS

The U.S. Food and Drug Administration (FDA) has approved Mavenclad (cladribine) tablets for the treatment of adults with relapsing forms of multiple sclerosis (MS), including relapsing-remitting MS (RRMS) and active secondary progressive disease (SPMS). Up to 85 percent of people with MS are initially diagnosed…

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.

Multiple sclerosis patients who began treatment with Gilenya and stayed with it continuously showed a more than 50 percent reduction in annual relapse rates, a real-world study following these people for up to three years found. Gilenya, marketed by Novartis, is an oral disease-modifying treatment for relapsing-remitting multiple sclerosis , approved in 2010. It acts by binding and modulating receptors — called sphingosine-1-phosphate receptor — on lymphocytes (adaptive immune cells). By binding to these receptors, Gilenya prevents lymphocytes from leaving the lymph nodes and reaching the brain and spinal cord, and so lower lymphocyte-induced inflammation and damage. Although several clinical trials have reported reduced annualized relapse rates (ARRs) upon treatment with Gilenya, few long-term real-life studies have examined the relapse rate reductions over a long term. A team, led by Novartis researchers and a scientist at Central Texas Neurology Consultants, collected MS patient data from the MarketScan database, a U.S. claims database including medical and pharmacy claims (bills submitted to health insurance providers), between 2009 and 2016. Among 9,312 MS patients in the database with at least one filled Gilenya prescription, 1,599 adults (mean age, 46) met the study's inclusion criteria, including having at least one inpatient or two outpatient claims, and a total of four years of continuous health plan enrollment. Among these 1,599 patients, all used Gilenya for one year (cohort 1), 1,158 (72.4%) took Gilenya continuously up to the start of year two (cohort 2), and 937 (58.6%) used the therapy up to the start of year three (cohort 3). Baseline analysis — measures taken at the study's start — showed that the most common MS-linked symptoms were disorders of the optic nerve and visual pathways (reported in 22-24%), followed by fatigue/malaise (20-21%). Hypertension (20-21%) and depression (15-16%) were the most common physical and mental comorbidities, respectively. The mean annualized relapse rates (AARs) at baseline in these three groups of patients — cohorts 1 to 3 — ranged between 0.48 and 0.51. A consistent reduction in ARRs was seen in all three groups: cohort 1 had a 0.25 ARR at the close of the first year, for a 51% reduction from the baseline rate; cohort 2 a 0.22 ARR at the start of year two, for a  54% lowering in relapse rates from baseline; and cohort 3 had 0.23 ARR at the third year, amounting to a 53% reduction. As expected, when researchers calculated ARRs among patients with continuous Gilenya use over these three years, they found a greater reduction in annual relapse rates. Mean ARRs in continuous-use patients were 0.19 (a 61% reduction) during the first year, 0.18 (a 62% reduction) during the second year, and 0.18 (a 61% reduction) at the start of the third year. “This retrospective claims database study found that patients with MS who received fingolimod [Gilenya] therapy experienced a durable and sustained reduction in relapse rates over a 3-year period,” the researchers wrote, with findings representing “a durable reduction in relapse rates by [more than] 50%.” Reasons that some patients discontinued treatment were not a focus of this study, they added.

A protein called MMP-9 could be a predictive marker of progressive multifocal leukoencephalopathy development in patients with relapsing-remitting multiple sclerosis (RRMS) who are being treated with Tysabri (natalizumab), a study suggests. The study, “Dynamic changes of MMP-9 plasma levels correlate with JCV reactivation and immune activation in natalizumab-treated multiple sclerosis patients,” was published in the journal Nature Scientific Reports. Brain inflammation in multiple sclerosis patients occurs when immune cells breach the blood-brain barrier. This layer of cells protect the brain and its supporting fluids, such as cerebral spinal fluid (CSF), from dangerous agents circulating in blood. How easily immune cells can break through the blood-brain barrier depends on its porousness. For instance, it is known that decreasing the activity of matrix metalloproteinases (MMP) increases the protective layer’s permeability. Matrix metalloproteinases are a family of proteins responsible for the degradation of collagen and other proteins in the extracellular matrix, which provides structural and biochemical support to surrounding cells. One metalloproteinase, called MMP-9, has been extensively studied in multiple sclerosis. MMP-9 levels are elevated in the CSF of multiple sclerosis patients and considered a potential biomarker of disease activity and possible therapeutic target. Tysabri (marketed by Biogen) is one of the most effective treatments for RRMS currently available. It works by blocking the entry of immune cells into the brain. Tysabri is known to decrease MMP-9 levels in the CSF and serum in RRMS patients. However, Tysabri has been associated with an increased risk of developing progressive multifocal leukoencephalopathy (PML). This rare and often fatal viral disease, caused by the John Cunningham virus (JCV), is characterized by progressive damage and/or inflammation at multiple sites in the brain. The reduced migration of immune cells across the blood-brain barrier induced by Tysabri is thought to be the cause of this increased PML risk. Whether MMP-9 is involved in this process has not been studied. To look at this, a team led by researchers from Sapienza University and Aldo Moro University in Italy investigated MMP plasma levels following Tysabri treatment in the context of JCV. The team specifically looked at how levels of MMP-9 were linked to disease-related processes. Samples from 34 RRMS patients being treated with Tysabri (intravenous dose of 300 mg every four weeks) were analyzed. As expected, results showed that MMP-9 plasma levels stabilized within one year of Tysabri treatment (up to 12 Tysabri infusions), although they began to steadily rise afterward (between 12 and 24 infusions). These increased MMP-9 plasma levels were not associated with clinical relapses in RRMS patients. "MMP-9 levels increased in plasma accordingly with [Tysabri] infusion number," the researchers wrote. In comparing JCV-positive and JCV-negative samples, the researchers observed an increase in MMP-9 plasma levels in JCV-positive samples. This result suggested that JCV circulation in peripheral blood could be implicated in the increase of MMP-9 levels. Interestingly, increased MMP-9 plasma levels were found to be correlated with immune cell activation. "Our findings suggest a potential pathogenic role of MMP-9 in the development of progressive multifocal leukoencephalopathy during [Tysabri] treatment, and its possible use as a marker of JCV reactivation,” the researchers wrote. Future studies are nonetheless needed to confirm these findings in larger groups of RRMS patients.

Gilenya is linked to significantly lower annualized relapse rates in relapsing-remitting multiple sclerosis (RRMS) patients compared to Tecfidera or Aubagio, a study suggests. All three therapies showed similar effects on disability outcomes. Oral immunotherapies — including Novartis’ Gilenya, Biogen’s Tecfidera, and Sanofi Genzyme’s Aubagio — are currently standard therapies for RRMS treatment. But while these therapies are highly effective at modulating MS activity, studies comparing their efficacy on relapse and disability are missing. This is an important point for MS patients, so that if a change in oral therapies is needed (due to lack of tolerance, for example), the decision on a more suitable therapy is based on scientific evidence. To address this matter, a group of researchers used the MsBase, an international observational MS cohort study, to identify RRMS patients who had been treated with Gilenya, Tecfidera, or Aubagio for at least three months. The team compared Tecfidera versus Aubagio, Gilenya versus Aubagio, and Gilenya versus Tecfidera, specifically for the therapy’s impact on relapse activity, six-month disability worsening or improvement, and persistence of treatment. Relapse was defined as the occurrence of new symptoms or exacerbation of existing ones for a period of over 24 hours, at least 30 days after a previous relapse. Disability was assessed using the Expanded Disability Status Scale (EDSS); the six-month disability worsening or improvement were defined as an increase or a decrease by one value in EDSS. The study included 614 patients treated with Aubagio, 782 with Tecfidera, and 2,332 with Gilenya. Patients were followed over a median of 2.5 years. Patients’ characteristics at baseline differed among the three groups. Aubagio-treated patients tended to be older, with longer periods of disease, fewer relapses, and lower EDSS scores compared to the other two groups. Patients treated with Gilenya had higher EDSS and more relapses during the prior year, compared to those treated with Tecfidera. The majority of the patients had been treated with other immunotherapies prior to being given one of these three oral treatments. Results showed that Gilenya-treated patients had significantly lower annualized relapse rates than those treated with Tecfidera (0.20 versus 0.26) or Aubagio (0.18 versus 0.24), while patients taking either Tecfidera or Aubagio had a similar rate. However, during the 2.5-year period analyzed, researchers found no differences in disability accumulation or disability improvement among the three therapies. Regarding treatment persistence, Tecfidera and Aubagio were more likely to be discontinued than Gilenya. Overall, the results suggest that treatment with Gilenya may have a greater impact on relapse frequency in RRMS patients compared to Tecfidera and Aubagio, although the "effect of the three oral therapies on disability outcomes was similar during the initial 2.5 years on treatment," researchers said. “Choosing a therapy in individual patients remains a complex task that requires thorough and individualized evaluation of disease prognosis, and the corresponding risks and benefits of the increasing number of available therapies,” they concluded.
