DMT Choice for Your MS Is Your Decision

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…

Tecfidera May Work to Lower Relapses by Inducing Epigenetic Changes in T-cells, Study Suggests

TreatingĀ 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 ā€” 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 ofĀ Tecfidera (by Biogen) for people with relapsing-remitting forms of the disease.Ā However, their complete mechanism of action remains unclear. Aiming to address this gap, scientists at theĀ Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New YorkĀ and theĀ 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) ā€” marketed asĀ CopaxoneĀ byĀ Teva Pharmaceuticals, with generic forms byĀ SandozĀ (asĀ Glatopa) and byĀ Mylan. All patients had stable disease for at least three months, but disease duration was shortest in untreated patients ā€” 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 typicallyĀ have an activated formĀ 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,Ā treatmentĀ 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 ā€” the addition of methyl groups ā€” in T-cells containing CD4, compared to glatiramer acetate. Specifically, this overmethylation was observed in a micro-RNA ā€” tiny RNA molecules than control gene expression ā€” 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 beenĀ implicatedĀ in MS. The epigenetic effects of FAEs were subsequently validated by comparing pre- to post-treatment with Tecfidera in seven patients. In turn, in vitroĀ (lab dish) experiments showed that FAEs act specifically on the activation of naĆÆve T-cells ā€” those able to respond to new pathogens to the immune system ā€” 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 studyā€™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 studyā€™s senior author, concluded:Ā "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."

Gilenya Better at Lowering Relapse Rate than Tecfidera or Aubagio, Study Suggests

Gilenya is linked to significantly lower annualized relapse rates in relapsing-remitting multiple sclerosis (RRMS) patients compared to Tecfidera orĀ Aubagio, a study suggests. All three therapies showed similar effects on disability outcomes. Oral immunotherapies ā€” including Novartisā€™ Gilenya, Biogenā€™s Tecfidera, and Sanofi Genzymeā€™s Aubagio ā€” 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 therapyā€™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. Patientsā€™ 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. ā€œChoosing 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,ā€ they concluded.
