Overreactive T-cells Can Transition into T-cells That Control the Immune Response, Study Shows

New research shows that overreactive and tissue-damaging T-cells can transition into regulatory T-cells that help to control the immune system’s response. These findings open the door to further understanding of the mechanism underlying this transition, knowledge that can help scientists in designing more effective, targeted immunotherapies for diseases like multiple…

#EAN2018 – Mavenclad Greatly Reduces Risk of RRMS Relapse, Analysis Finds

New retrospective analysis of the Phase 3 CLARITY study (NCT00213135) shows that treatment with Mavenclad (cladribine tablets) improved annualized relapse rate and magnetic resonance imaging (MRI) outcomes in patients with relapsing-remitting multiple sclerosis (RRMS), regardless of their age. Moreover, the effectiveness of Mavenclad was comparable to five standard therapies…

#CMSC2018 – Gains in Functional Abilities Seen in Lemtrada-treated MS Patients Over Six Years, CARE-MS II Extension Study Shows

Patients with active relapsing-remitting multiple sclerosis (MS) continue to show improvement — lesser functional disability across a variety of measures — and often without the need for continuous treatment after taking Lemtrada for two years, according to six-year results from the CARE-MS II extension study. These results were shared in a…

New Class of Anti-inflammatory Compounds May Help Halt Inflammation in MS, Study Suggests

A new class of indoline derivatives shows potent antioxidant and anti-inflammatory activities capable of decreasing inflammation in the brain, new research shows. This finding highlights the potential of the new compounds in chronic inflammatory diseases, such as multiple sclerosis (MS). The study “Synthesis and Biological Evaluation of Derivatives of Indoline as…

#AAN2018 — Ocrevus Lowers Immune Response to Vaccines in Relapsing MS, Phase 3 Trial Shows

Treatment with Ocrevus (ocrelizumab) is linked to a reduced immune response to vaccinations in patients with relapsing multiple sclerosis (MS), according to a Phase 3 trial. These results were recently presented at the 2018 American Academy of Neurology (AAN) Annual Meeting in Los Angeles in a presentation titled, “Effect of Ocrelizumab on Vaccine Responses in Patients With Multiple Sclerosis.” Genentech’s Ocrevus is an approved MS therapy that targets the CD20 protein located on the surface of B-cells, targeting the cells for destruction. B-cells are immune system cells involved, for example, in the production of antibodies necessary to fight off infection. At the AAN meeting, researchers reported that in MS patients, treatment with Ocrevus decreased the ability of B-cells to activate other immune cells, improving the rate of MS attacks. Penn Medicine neurologist Amit Bar-Or, MD, presented these findings, which showed that interactions between different classes of immune cells, such as B- and T-cells, promote MS attacks. Vaccination against infections is an important part of the management of patients with MS. So, in a second study (NCT02545868), researchers investigated the impact treatment with Ocrevus has on patient response to vaccines. They recruited 102 patients with relapsing MS and randomized them in two groups. In group A, 68 people received a single dose of 600 mg Ocrevus (administered into the blood); in group B, 34 patients received no disease-modifying therapy or interferon-beta. All patients were then administered vaccines for tetanus, seasonal flu, and pneumococcus. Patients in group A received the vaccines 12 weeks after they were treated with Ocrevus, while group B patients received the vaccines on day one. Researchers also tested patients’ response to a novel protein (an antigen) never "seen" by their immune system, called keyhole limpet hemocyanin (KLH) neoantigen. The vaccinations led to an immune system response in all patients, but the level of response in patients treated with Ocrevus was lower. A positive response to the tetanus vaccine at eight weeks after treatment was 23.9% in group A (Ocrevus) compared with 54.5% in group B (no treatment); the response to pneumococcus vaccination was 71.6% in group A and 100% in group B. After four weeks of treatment, the levels of antibodies against the different strains of the flu virus were lower in Ocrevus-treated patients than in the control group, ranging from 55.6% to 80.0% in the Ocrevus group compared with 75.0% to 97.0% in the controls. The immune response to the neoantigen KLH was also decreased in the Ocrevus group. "This study shows that while people with MS treated with ocrelizumab [Ocrevus] can still mount vaccine responses, it's not nearly as strong as prior to treatment," Bar-Or said in a press release. "While antibody responses were reduced in the ocrelizumab treated patients, they still responded to a certain level," he said. "This is valuable information in terms of seasonal vaccines such as the flu — it appears safe for patients taking ocrelizumab to get vaccinated and vaccination is likely to provide them with at least some protection from such infections." These findings correlate with standard guidelines that advise patients to undergo vaccinations six weeks before they start treatment with Ocrevus.

#AAN2018 – High Fish Consumption Linked to Lower MS Risk

A diet rich in fish consumption and supplemented with omega-3 polyunsaturated fatty acids (PUFAs) is linked to a reduction of 45 percent in the risk of developing multiple sclerosis, a study shows. The results confirming previous research will be shared April 26 at the 2018 Annual Meeting of the American Academy of…

#AAN2018 – Blood Stem Cell Transplant Superior to DMDs in Highly Active RRMS, MIST Trial Shows

Autologous non-myeloablative hematopoietic stem cell transplant was found to be significantly better at reducing risks for disability in relapsing-remitting multiple sclerosis (RRMS) patients compared to disease-modifying drug (DMD) therapies, interim results of the MIST clinical trial show. The results will be shared at the 2018 Annual Meeting of the American…

#AAN2018 – Switching from Rebif to Ocrevus Improves MS, Extension Study Shows

Continuous treatment with Ocrevus (ocrelizumab) or switching from Rebif (interferon beta-1a) to Ocrevus leads to a significant long-term reduction in relapsing multiple sclerosis activity, a two-year extension study shows. Ocrevus’s maker, Genentech, drew the results from an open-label extension of the Phase 3 OPERA trials. Researchers will present the findings at…
