About 15 disease-modifying therapies (DMTs) are available to treat MS these days. So, choosing which to use can be daunting. I’ve been treated with four DMTs since I was first prescribed Avonex (interferon beta-1a) back in 1996. Each time I’ve switched treatments, my neurologist has suggested a number of…

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."

Alkermes and Biogen have begun working together on a compound known as ALKS 8700 as a potential treatment for relapsing forms of multiple sclerosis. Under the agreement, Alkermes will be responsible for obtaining regulatory approval of the drug, while Biogen will handle its marketing. ALKS is taken orally. The body quickly transforms it into a compound known as monomethyl fumarate that can counter MS. Aikermes designed it to have better features than Tecfidera (dimethyl fumarate) — in particular, fewer gastrointestinal side effects. The partnership gives Biogen worldwide marketing rights to ALKS 8700. Alkermes will receive a royalty on global sales. Aikermes is evaluating ALKS 8700's safety and effectiveness in what it has dubbed the EVOLVE-MS clinical trial program. It includes two Phase 3 trials that are comparing ALKS 8700 with Tecfidera in patients with relapsing-remitting MS, or RRMS. Preliminary results of the EVOLVE-MS-1 trial, which involved 580 patients, showed few gastrointestinal side effects from ALKS 8700. The most common adverse events in the first month of treatment were flushing, diarrhea, and a rash known as pruritus. Aikermes discussed the treatments safety, and patients' ability to tolerate it, at the 7th Joint ECTRIMS-ACTRIMS Meeting in Paris in October. The company is still recruiting participants for a second trial that will compare ALKS 8700 and Tecfidera's effect on the gastrointestinal system. The EVOLVE-MS-2 study will  be conducted at locations in several U.S. states and six sites in Poland. Alkermes expects to release initial findings from the trial in the first half of 2018.

Preliminary data from the Phase 3 EVOLVE-MS-1 trial shows that ALKS 8700 — an investigative therapy developed by Alkermes to treat relapsing forms of multiple sclerosis — has a good safety and tolerability profile. ALKS 8700 is an oral compound. Once inside the body, it is rapidly transformed into the therapeutic compound monomethyl fumarate (MMF). Although similar, this drug candidate was designed to offer features different than those achieved with the commercially available Tecfidera (dimethyl fumarate). Alkermes is currently assessing the safety and efficacy of ALKS 8700 in the EVOLVE-MS program, which includes two Phase 3 clinical trials in patients with relapsing-remitting MS. The EVOLVE-MS-1 is a two-year study being conducted in 107 U.S. and European research sites. It will evaluate the long-term safety of ALKS 8700 in some 930 RRMS patients. Interim data collected during the first month of treating 580 participants showed low incidence of GI adverse events, with no reports of serious events. The most common adverse side effects associated with the treatment were flushing, pruritus and diarrhea. Alkermes, which is based in Ireland, said additional results from the initial three months of treatment further supported the positive safety data of ALKS 8700, with only 2.3 percent of patients reporting serious adverse events and 3.7 percent having to stop treatment. The EVOLVE-MS-2 trial, being conducted at 48 U.S. sites, will compare the safety and efficacy of ALKS 8700 versus Tecfidera in RRMS patients. The study is still recruiting participants. Recent data of EVOLVE-MS-2 was also subject of a poster presentation at the ECTRIMS-ACTRIMS Meeting.

Alkermes will showcase its work in developing a treatment that harnesses the effect of Tecfidera (dimethyl fumarate) for relapsing multiple sclerosis (MS), while lowering the risk of stomach problems at the 7th Joint ECTRIMS-ACTRIMS Meeting this month in Paris. The investigational drug, ALKS 8700, uses the same mechanism of action as Tecfidera. By building the molecule in a different way, however, the company expects it will show better tolerability. Once in the body, dimethyl fumarate turns into monomethyl fumarate (MMF), the molecule that actually impacts MS disease processes. But before giving rise to MMF, dimethyl can cause side effects in users, particularly gastrointestinal. In fact, stomach problem were what caused people in Tecfidera Phase 3 trials to stop the treatment. Alkermes uses a so-called prodrug approach to try to overcome this problem. By attaching a different compound to MMF — which breaks away from the molecule once in the body —  it is possible to deliver MMF with lesser gastrointestinal side effects, Phase 1 study data indicate. At the meeting, the company will present two posters on two clinical trials exploring ALKS 8700 in patients with relapsing-remitting MS. The first presentation, will describe a Phase 3 trial that aims to compare ALKS 8700 to Tecfidera in about 420 patients. The trial is primarily concerned with the drug’s safety, and will measure the occurrence and impact of gastrointestinal side effects in the two treatment groups. The presentation will only include descriptions of patients characteristics and study design, as outcomes are yet to be analyzed. Patients who complete the Phase 3 trial will be eligible to continue in an ongoing open-label, long-term safety study, called EVOLVE-MS-1, covered in the company’s second presentation. By March 3, 2017, the study had enrolled 543 patients. In addition to describing patient characteristics, researchers will present the rates of discontinuation caused by gastrointestinal adverse events within one month of starting the treatment.
