Assessing changes in a person’s heart rate can help to predict the degree to which lymphocyte numbers will decrease in relapsing-remitting multiple sclerosis (RRMS) patients using Gilenya (fingolimod), according to a small study. The research, “Fingolimod-induced decrease in heart rate may predict subsequent decreasing degree of…

Substantial data supporting both the effectiveness and safety of Mavenclad (cladribine tablets) is before the U.S. Food and Drug Administration (FDA), and may lead to its approval as a short-course oral treatment for people with relapsing-remitting multiple sclerosis (RRMS) some seven years after a first such request…

Multiple sclerosis patients using Rebif (interferon beta-1a) are not at an increased risk of a stroke, even if remaining on this therapy for more than two years,  a study analyzing safety data from more than a dozen clinical trials and post-marketing surveillance shows. The…

Ocrevus (ocrelizumab) is a serious disease-modifying therapy. It has the potential to deliver a major blow to a patient’s MS, but it also carries the possibility of severe side effects. The protocol for Ocrevus requires different doses on different infusion dates, following a specific treatment schedule. It’s also…

Hair thinning in relapsing-remitting multiple sclerosis (RRMS) patients using Aubagio is usually mild and temporary, and does not require stopping treatment, a small real-world study reports. The research, “Real-World Observational Evaluation of Hair Thinning in Patients with Multiple Sclerosis Receiving Teriflunomide: Is It an Issue in Clinical…

In mid-July, the woman who writes the Multiple ExperienceS blog had a little fall. As Jamie explains, her rollator went forward, but her feet didn’t. The fall left a small cut on her knee. Over the next few days, Jamie’s knee swelled, and a trip to her doctor,…

Cladribine tablets added to interferon-beta treatment significantly reduced the probability of relapses over 96 weeks in people with active relapsing multiple sclerosis , a Phase 2 clinical trial found. But a troubling diminishment in key immune cells was also seen in treated patients. Relapsing-remitting MS is marked by periods of flares caused by inflammatory attacks, followed by periods of partial or complete recovery . A majority --about 65 percent -- go on to develop secondary progressive MS. Despite the growing number of treatment options — including disease-modifying therapies — for these MS patients, efforts continue into better ways to lower relapse frequency and slow disease progression. Researchers tested the safety and efficacy of cladribine tablets as an add-on therapy in patients continuing to experience active relapses while under interferon-beta treatment. Cladribine is an oral medication that works by selectively targeting and reducing the number of immune cells involved in the inflammatory attacks occurring in active MS. It was developed by EMD Serono (Merck KGaA outside the U.S. and Canada) and approved in the European Union using the brand name Mavenclad (it is not approved in the U.S. for MS). Interferon-beta works by balancing pro- and anti-inflammatory signals, reducing the number of immune cells and promoting the survival of nerve cells. Interferon-beta therapies are marketed under several brand names; in the study, researchers analyzed patients using Rebif (marketed by EMD Serono), Avonex (by Biogen), and Betaseron/Betaferon (by Bayer). The 96-week, randomized, double-blind, Phase 2b trial called ONWARD enrolled a total of 172 patients with active relapsing MS, who were randomly divided into two groups: those given cladribine tablets together with interferon-beta, and those that received a placebo and interferon-beta. Results showed those taking cladribine tablets together with interferon-beta had 63% lower likelihood of a relapse compared to those given an add-on placebo. Add-on cladribine treatment also reduced most measures of disease activity as assessed by magnetic resonance imaging (MRI) — namely, the number of new brain and spinal cord lesions. However, almost half of patients in this treatment group developed lymphopenia, a condition where the levels of lymphocytes (important immune white blood cells) in the blood are abnormally low. None in the control group developed the condition. Other reported side effects, including other serious adverse side effects, were identical in the two groups. Altogether, the findings indicate that a cladribine and interferon-beta combination can successfully lower the probability of relapses over the course of 96 weeks, but also increase a person's chances of lymphopenia.

A genetic variant close to a gene called interferon regulatory factor 6 (IRF6) may help to predict those multiple sclerosis (MS) patients most at risk of liver injury while using interferon-beta therapies, a study reports. The study, “Common variation near IRF6 is associated with IFN-β-induced liver injury in multiple sclerosis” was published…

I’m now three months past my second round of Lemtrada treatments, so it’s time for an update. I began Lemtrada (alemtuzumab) in December 2016, hoping it will be the last disease-modifying therapy that I’ll ever need to use. I’ve had peaks and valleys since this treatment began, thus…

A review of data concerning the multiple sclerosis (MS) medicine Zinbryta (daclizumab) confirmed its association with the risk of developing severe and potentially fatal immune reactions in the brain, liver and other organs, according to the European Medicines Agency’s (EMA)’s Pharmacovigilance Risk Assessment Committee (PRAC). Zinbryta was authorized…

A case study reported the successful management of a multiple sclerosis (MS) patient who developed a rare condition in the brain — progressive multifocal leukoencephalopathy (PML) — due to treatment with Novartis Pharmaceutical’s Gilenya (fingolimod). The study, titled “Fingolimod-associated PML with mild IRIS in MS: A…

Part two in a series. Read part one here. In the last column, I discussed gadolinium’s role in contrasted MRI procedures and a December 2017 warning by the U.S. Food and Drug Administration that the body can retain gadolinium in its tissues and brain for years. I also shared my personal experience with…

When a doctor orders an MRI with contrast, gadolinium is usually the contrasting agent used. Gadolinium is injected into the patient’s vein after the radiologist takes the first round of MRI images. This helps the radiologist receive sharper, more readable images. In the case of multiple sclerosis (MS),…

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.

Acute Acalculous Cholecystitis Linked to Lemtrada Use in RRMS Patients, FDA Reports The makers of Lemtrada have added the possibility of another serious side effect to the warning carried on the therapy’s label. The addition follows a Food and Drug Administration review that discovered a potentially serious…

Higher rates of adverse effects have a negative impact on a patient’s perspective about treatment with Ocrevus (ocrelizumab), according to a survey conducted by the multiple sclerosis community GeneFo. About half of the 840 patient responses surveyed so far have reported improvements from Ocrevus. Those reporting none had a higher rate…

Acute acalculous cholecystitis (AAC) is a rare but potentially life-threatening adverse effect linked to treatment with Lemtrada (alemtuzumab) in patients with relapsing-remitting multiple sclerosis (RRMS), according to a U.S. Food and Drug Administration review. The study, “Acute acalculous cholecystitis — A new safety risk for…

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,…

Six months ago, I was a reasonably svelte 14 and a half stone. I’m not sure how I managed it, but it was certainly before pitting edema wrapped itself around my shins and calves like bulbous sacks of wineskins. I managed to get on the scales a while…

Biogen and AbbVie have voluntarily withdrawn global marketing authorizations for their relapsing multiple sclerosis therapy Zinbryta (daclizumab) because of serious side effects that include brain inflammation. The Europe Medicine Agency, which oversees medications across the European Union, also released a statement recommending a “immediate suspension” of Zinbryta’s use by patients and…

Usually, I’ve got a fair idea of where I’m headed in my column. This time, I really don’t. I’m confronting something. Maybe nothing. It’s as clear as the cliché involving wet, clingy earth. For the first time since the last week in November 2017, I’ve stopped taking antibiotics. That’s…

Pregnant women with multiple sclerosis (MS) exposed to Tysabri (natalizumab) in the first trimester had higher rates of miscarriage and major birth defects in their babies, than women left untreated or treated with interferon beta, a study shows. Although higher, these rates were similar to those in the general…

A combination of an anti-viral therapy and the anti-depressive mirtazapine can stop the worsening of an infection linked to the multiple sclerosis therapy Tysabri (natalizumab), a case study suggests. The infection, John Cunninghan polyomavirus, can cause a potentially fatal brain infection known as  progressive multifocal leukoencephalopathy, or PML. Both…

The Food and Drug Administration (FDA) issued a safety alert about gadolinium, the dye that’s injected when our doctors order a brain MRI “with and without” contrast. The dye provides the contrast that “lights up” areas of MS inflammation in the brain. But the FDA advisory is…

The U.S. Food and Drug Administration (FDA) has updated a safety bulletin about gadolinium-based contrast agents (GBCAs), after studies raised new concerns about them. Doctors often use GBCAs to diagnose multiple sclerosis (MS), monitor disease activity and verify the effectiveness of MS therapies. Gadolinium is a metal ion, or electrically charged molecule, that…

Editor’s Note: First in a two-part series on readers’ comments about Ocrevus (ocrelizumab). I switched disease-modifying therapies and began treatment with Ocrevus (ocrelizumab) in June. I previously wrote about my reasons for switching, my experiences with the first two doses, and more recently, about any…

Lemtrada (alemtuzumab) remains a “game-changer” of a treatment for relapsing multiple sclerosis (MS), with benefits continuing and no new side effects seen in a study of its use that now goes out seven years, Aaron Boster, a neuroimmunologist at Ohio Health, said in an interview at the…

Sanofi Genzyme’s multiple sclerosis therapy Aubagio (teriflunomide) does not appear to cause birth defects in humans as it does in laboratory animals, researchers concluded after studying more than 100 pregnant women with MS. Their research indicated that birth-defect findings in rats and rabbits do not translate to humans. The team presented its…

Babies born to women who are treated with Tysabri (natalizumab) during pregnancy are more likely to develop abnormal blood cell counts if the treatment continues beyond week 30 of pregnancy. Since more relapses occurred in women who quit the treatment before this time, researchers from the Ludwig Maximilian University…
