side effects

More than four years of treatment with Gilenya (fingolimod) did not cause significant swelling of the macula — a part of the retina, found in the back of the eye, and important for visual clarity — in people with relapsing-remitting multiple sclerosis (RRMS), a small study showed. While…

Differences in the composition of the gut microbiome are associated with an altered risk of low immune cell counts as a side effect of treatment with the multiple sclerosis (MS) therapy Tecfidera (dimethyl fumarate). The findings provide further insights on how the gut microbiome — the billions of…

Persistent use of a single disease-modifying therapy (DMT) over a three-year period was low among people with relapsing forms of multiple sclerosis (MS), a U.S. study found. DMT discontinuations or switches were initiated in some cases by prescribers, specialty pharmacists, or patients for reasons that included treatment side…

Long-term treatment with Gilenya (fingolimod) in routine clinical practice is safe and effective for relapsing-remitting multiple sclerosis (RRMS), a five-year study in Germany of more than 4,000 patients reported. Over time, relapses in the majority of study patients who continued with Gilenya became less common and less severe,…

Side effects upon receiving the COVID-19 vaccine in people with multiple sclerosis (MS) are similar to those reported in the general population, and patients on certain disease-modifying therapies are less likely to have vaccine reactions, a survey-based study found. The findings provide “a reassuring picture” for those who feel hesitant about…

Skin reactions are common among relapsing-remitting multiple sclerosis (RRMS) patients being treated with oral Mavenclad (cladribine), affecting about one-third of the people evaluated in a real-world study in Germany. These findings suggest the need for careful clinical surveillance to rapidly diagnose and possibly treat skin problems stemming from Mavenclad’s use,…

Last week, my wife and I were back in Bowie, Maryland, for our second shot of the Moderna COVID-19 vaccine. It was a sunny and warm afternoon after a windy, cold, and wet month. We hoped that was a good omen. Nina, the same pharmacist who gave us our…

I was 6 years old when British boxer Henry Cooper knocked Cassius Clay on his bottom. (It was that long ago, folks — 1963. This was before Clay’s religious conversion and consequent name change to Muhammad Ali.) Unfortunately, Clay was literally saved by the bell. I remember dashing around…

New or worsening headaches are a more common side effect of interferon-beta (IFN-beta) treatment in people with multiple sclerosis (MS) than previously appreciated, a new study suggests. The study, “Interferon-Beta-Induced Headache in Patients with Multiple Sclerosis: Frequency and Characterization,” was published in the Journal of Pain Research.

I have secondary progressive multiple sclerosis and I am rare. In honor of Rare Disease Day on Feb. 29, I honor myself. I honor you and anyone else with a rare disease. I have been asked if multiple sclerosis qualifies as a rare disease. It does if…

I was bruised, broken, and in pain. I had been struggling with Rebif (interferon beta-1a) side effects for over a year, ever since my diagnosis. It was the first multiple sclerosis medication doctors put me on, and it did not work…

It’s time for another update on how I’ve been doing with my Lemtrada (alemtuzumab) treatments. The bottom line is that I’m doing well. Lemtrada is a disease-modifying therapy (DMT) delivered in two stages. The first stage entails a series of five daily infusions, while the second stage involves…

A twice-daily dosing schedule and side effects like nausea and flushing are key reasons why more than 10% of multiple sclerosis (MS) patients followed for a year stopped using Tecfidera (dimethyl fumarate) as prescribed, a single-site study reports. Adherence to treatment is key to patients’ health, and doctors should not…

For the last few months, urinary tract infections (UTIs) have been the main subject of this column. My current disease-modifying therapy, Ocrevus (ocrelizumab), has had a significant impact on my multiple sclerosis (MS). The only downside is that Ocrevus attacks B-cells in the body, increasing the risk…

The European Medicines Agency (EMA) is reviewing safety data for Sanofi Genzyme‘s Lemtrada (alemtuzumab) following new reports of serious treatment side effects. Lemtrada is a humanized monoclonal antibody used to slow disease progression in adult patients with relapsing-remitting multiple sclerosis (RRMS). It works by blocking the activity of…

Nearly 18% of new multiple sclerosis (MS) patients referred to two speciality clinics in Los Angeles, California, had been misdiagnosed with the disease, according to a recent study. Most of them actually were affected by migraines, among other…

Usually, I have an idea of what I’m going to write. Today, all I feel is a bit meeeeugh … Which is more a sound of ennui than a recognizable word. In these days of multimedia, I suppose I should record it and insert the clip into the text, but…

Many multiple sclerosis (MS) patients report that cannabis has beneficial effects on their symptoms with minimal side effects, according to a survey that also showed that varying effects on health may be due to differences in how users consume cannabis. Findings from the survey were reported in the…

Over the past couple of weeks, two warnings have been issued about side effects of multiple sclerosis (MS) medications. First, the U.S. Food and Drug Administration warned about a slight risk of seriously worsening MS symptoms if someone who is using the disease-modifying therapy (DMT) Gilenya (fingolimod) stops using…

I’m not taking all the medication I’ve been prescribed. Chances are, you’re not either. Medication nonadherence, or not taking medicine as prescribed, is a thing — a big thing. According to a column in The New York Times,…

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,…

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.

Aubagio (teriflunomide) may lead to reversible nail loss, researchers at Italy's University of Bologna reported after reviewing the case of a 55-year-old woman with relapsing-remitting multiple sclerosis. They described what happened to a patient who was referred to an MS clinic after experiencing acute optic neuritis — or inflammation of the optic nerve — three months earlier. Their report, “Nail loss after teriflunomide treatment: A new potential adverse event,” was published in the journal Multiple Sclerosis and Related Disorders. Doctors had been treating the woman with intravenous methylprednisolone. Physicians had judged her slightly disabled, with an Expanded Disability Status Scale (EDSS) score of 3, but had not diagnosed her with MS. When she was diagnosed a few months later, she began receiving interferon beta-1a. It did not work, so doctors switched her to Sanofi Genzyme's Aubagio. At first, she tolerated the treatment well, having only slight nausea after taking the medication. Physicians did not detect signs of liver toxicity or high blood pressure, which are relatively common side effects of Aubagio. Roughly three months after starting the medication, however, the woman began having more trouble walking problems and had mild hair loss. Two and a half months later, she said her nails had started falling out in the past month. When doctors examined her, she had lost two nails, while others appeared to have stopped growing. They were thinner than normal and some had detached from the nail bed. In addition, her hair loss continued. She had not started using other drugs, new cosmetics, or changed her diet. A dermatologist excluded the possibility that the condition was the result of fungus, psoriasis, or other conditions that could cause nails to fall off. Because doctors suspected that Aubagio could be the cause of the nail loss, they recommended that she stopped taking it. The patient switched to Biogen's Tecfidera (dimethyl fumarate) after a couple of weeks, and her nails started to grow again. This supported doctors’ idea that Aubagio had caused the nail loss, and that it was reversible. Nail growth is similar to that of hair, researchers said. The patient’s reaction could be an unusual version of the same process that makes people lose their hair when taking Aubagio, they said. Since nail loss is not described as a side effect of Aubagio on the medication's label, researchers urged MS specialists to consider the possibility if they see patients with the problem.  

As I write, I’m pain-free. This is important, but not for the obvious reason. I’m pain-free and can walk — or at least stumble — about as best as I’ve been able to manage of late. It’s not much, but I can be involved in family life and get…

I was a teenager during the 1980s and cannot say the word “holiday” without Madonna’s song playing briefly in my head. For most holidays the perky music seems okay, but for discussion of a “drug holiday” it feels a bit off. Sort of like, “Yay! You have a chronic…

With the recent approval of Ocrevus (ocrelizumab) for both primary progressive and relapsing multiple sclerosis (MS), interest in the medication is peaking. To help readers of Multiple Sclerosis News Today better understand this new medication and how it works, as well issues dealing with access, use, and potential side effects, here is a summary…

There is now less than a month until the U.S. Food and Drug Administration (FDA) is expected to approve Ocrevus, generic name ocrelizumab, for use as a therapy for multiple sclerosis. Clinical trials have shown Genentech’s drug to be a promising therapy for relapsing MS and, significantly,…

Treatment with a compound called BIIB074 shows promise in reducing pain caused by trigeminal neuralgia — a  condition that occasionally affects multiple sclerosis (MS) patients — with few side effects, a new clinical trial finds. The Swiss study, “Safety and efficacy of a Nav1.7 selective sodium channel blocker in Titrigeminal neuralgia:…

Interferons (Beta and Alpha) are the oldest of the disease-modifying treatments, or DMTs, for people with MS. Interferons include Avonex, Betaseron, Rebif, and Plegridy. This column won’t get into the pros and cons of each of these treatments. Instead, I’d like to focus on one of the more…
