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.

I saw my neurologist a few weeks ago for what was effectively an emergency meeting. I’d had the customary two rounds of Lemtrada (alemtuzumab) and still had a relapse. We discussed weighty subjects and there seemed, surprisingly, to still be some hope. It depends on the outcome of an MRI;…

The American Academy of Neurology (AAN) has just released some new guidelines about when to begin, change, and end disease-modifying therapies (DMTs) that are used to treat MS patients. The guidelines, published on April 23, encourage aggressive treatment when symptoms of MS first appear. They’re also patient-centric. And…

Autologous hematopoietic stem cell transplantation, also known as aHSCT, has been shown to be safe and highly effective to treat patients with "aggressive" multiple sclerosis. Tested in 19 patients, transplantation of stem cells was found to induce clinically meaningful improvements in disability. These findings were shared at the 2018 Annual Meeting of the American Academy of Neurology (AAN) in Los Angeles, California. aHSCT uses a patient’s own healthy bone marrow stem cells, in combination with a much less aggressive chemotherapy and/or radiation regimen, to prepare the patient for the transplant. Previous studies have suggested that aHSCT is an effective strategy to treat patients with highly active relapsing-remitting MS (RRMS) who do not respond to available disease-modifying therapies (DMTs), and international guidelines advocate for its use in patients with "aggressive" MS. To further demonstrate the potential of aHSCT as a treatment for "aggressive" MS, a research team evaluated its safety and effectiveness in MS patients who had not been treated previously with DMTs. A total of 19 patients were treated across several clinical centers: seven patients were from Sheffield, U.K., seven from Uppsala, Sweden, four from Ottawa, Canada, and one patient was from Florence, Italy. All patients received aHSCT between May 2004 and May 2017. In addition to aHSCT, patients were treated with BEAM (carmustine, etoposide, cytarabine, melphalan) chemotherapy plus antithymocyte globulin (ATG) to reduce transplant rejection, or with Cytoxan (cyclophosphamide) with ATG, or the triple combination of Cytoxan, ATG, plus busulfan as conditioning regimens. Patients had a median age of 33 years at diagnosis and received the aHSCT by a median time of nine years after symptom onset. They had a median disability score of 6.5 before the treatment, as determined by the Expanded Disability Status Scale (EDSS). After a median follow-up period of 30 months, patients had a median EDSS score of 2.0, which represented a median improvement of 2 points (the higher the score, the worse the patient's disability level). None of the patients had clinical relapse following the transplant of stem cells. Only three patients developed new brain lesions detectable by magnetic resonance imaging (MRI) at the first six-month follow-up evaluation, but no additional new lesions were detected in the following scans. The adverse effects reported during the study were comparable to those previously observed in similar treatments. No deaths related to the treatment were reported. Based on these preliminary results, the researchers concluded that aHSCT is “safe and highly effective in inducing rapid and sustain remission” in highly active MS, and "was associated with a significant improvement of [patient’s] level of disability.” “aHSCT should be considered as first line therapy in patients with ‘aggressive’ MS,” the team concluded. Another study presented at the AAN 2018 meeting further supports these findings, demonstrating the superior effectiveness of aHSCT over conventional DMTs for RRMS.

A compound produced by immune cells is able to treat psoriasis – a skin disorder – in mice, and may be effective against other autoimmune diseases, such as multiple sclerosis, according to a recent study. The study, “Electrophilic properties of itaconate and derivatives regulate the IκBζ–ATF3 inflammatory…

Americans who want to treat their MS with a stem cell transplant have a tough road to follow. They’re forced to travel to Russia, Mexico, or somewhere else out of the country and to spend a lot of money to avoid the U.S. Food and Drug Administration’s stem cell…

With apologies to Edgar Allan Poe, quoth the Lemmie, “Nevermore.” As I write this, the final brown bag of Lemtrada (alemtuzumab) has just begun to drip into a vein in my left arm. If all goes “as advertised,” this will be the final disease-modifying therapy I’ll ever receive.

It’s been a little over a year since U.S. regulators approved Genentech’s Ocrevus (ocrelizumab) as the first treatment for both relapsing and progressive forms of multiple sclerosis (MS) — a disabling neurological disease now believed to affect nearly one million Americans. While the jury’s still out regarding the therapy’s…

The United Arab Emirates is the first country in the Middle East and Africa to approve Mavenclad (cladribine tablets) as a treatment for patients with highly active relapsing multiple sclerosis (MS) evidenced through imaging tests or clinical evaluation. The therapy is expected to become available once local regulatory…

As you read this, I likely will be in the middle of, or finished with, my second round of Lemtrada (alemtuzumab). Hopefully, this will be the final round of this disease-modifying therapy (DMT), and the final MS treatment of any kind, for me. Though some have required more,…

When and how to best use disease-modifying therapies (DMTs) in multiple sclerosis depends on key treatment decisions that, partly because the number of DMTs available, can be as challenging for clinicians as they are for patients. DMTs and their optimal use will be covered in the closing lecture of the…
