New data on how Lemtrada and Aubagio perform in a real-world setting will be the focus of Sanofi Genzyme when the company showcases its research at the upcoming 7th Joint ECTRIMS-ACTRIMS Meeting in Paris this week. Researchers will also share information about the safety of a new investigational therapy, GLD52 (GZ402668), currently in a Phase 1 safety study. The TOPAZ study is one of the main data sources for the upcoming presentations. The study, which follows relapsing MS patients who participated in the CARE MS-I and CARE MS-II extension study , is a rich source of information on long-term outcomes. Researchers will share various aspects of disease outcomes and magnetic resonance imaging (MRI) data from patients followed up to seven years, with some presentations focusing solely on those who switched from treatment with interferon beta-1a. Among the Lemtrada highlights are findings demonstrating that Lemtrada does not appear to trigger birth defects. Another presentation compared Lemtrada to Genentech’s Ocrevus using a model that evaluated both the cost and effectiveness of the two drugs. The analysis suggests that Lemtrada more effectively treated relapsing MS and was also linked to lower costs over a 20-year period. Aubagio studies also focused on long-term patient data, including in people with progressive forms of relapsing MS. Data from the Phase 3 TEMSO , TOWER , and the TEMSO extension showed that Aubagio stabilized disability progression in these patients over nearly a decade. Other presentations homed in on Aubagio’s ability to slow brain tissue loss and improve cognitive outcomes. Finally, Sanofi Genzyme shared initial data on its investigational antibody GLD52. The treatment is an updated form of Lemtrada, which scientists believe gives rise to fewer and milder infusion-related reactions. Data from the Phase 1 study , so far indicated that this might indeed be the case, as no severe reactions occurred in the 44 progressive MS patients in the trial.

MS drug manufacturers are in the sights of two members of Congress The companies are Bayer, Biogen, EMD Serono, Novartis, Sanofi Genzyme, Teva, and Roche. U.S. Reps. Elijah Cummings and Peter Welch, two Democrats who sit on the House Committee on Oversight and Government Reform, are concerned about what they're calling dramatic price increases for some MS drugs produced by those companies. In a news release, the congressmen say the price hikes have come "without warning, cause, or justification." They've sent letters to the companies seeking information about their profits and expenses. The letters also ask for documents about pricing strategies, patient assistance programs, and drug distribution systems. Cummings and Welch point to an American Academy of Neurology study of drug prices as evidence that some pharmaceutical companies appear to be increasing the prices of their older, less expensive drugs to bring those prices in line with those of the newer, more expensive DMTs that are available today. This kind of practice is known as “shadow pricing.” The congressmen refer to this study as being a bit dated, as it was published in May of 2015. It reviews the published prices of nine DMTs over a 20-year period, ending in 2013, and shows that prices for those older, first-generation DMTs increased at an annual rate that was five to seven times higher than general prescription drug inflation. In their news release, the lawmakers also referred to a report from the National Multiple Sclerosis Society that included a chart of drug price increases since the approval date for each drug.

Biogen is a big pharmaceutical company that produces a half-dozen MS drugs. Among them are Tysabri, Avonex and Tecfidera. And Biogen is doing all it can to protect its turf, particularly when it comes to its best seller, Tecfidera. Last month the company filed lawsuits against several…

A multiple sclerosis (MS) patient treated in Germany with Ocrevus (ocrelizumab) has developed the dreaded brain infection progressive multifocal leukoencephalopathy (PML). But it is not clear whether the recently approved Genentech/Roche-developed treatment is the cause. The patient took the last dose of a three-year course of Tysabri (natalizumab) in February. Tysabri is…

Recently approved, Ocrevus (ocrelizumab) should now be available nationwide for patients prescribed the therapy. But as with any new treatment, concerns about safety and practical issues are on many patients’ minds.

A ruling by the  U.S. District Court for the District of Delaware invalidated four of five patents held by Acorda Therapeutics that pertained to Ampyra (dalfampridine), a treatment for walking difficulties in multiple sclerosis (MS) patients, raising the possibility of generic forms of the drug coming onto the market in a…

With last month’s approval of the multiple sclerosis drug Ocrevus, I’ve again heard the plea “But how can I afford it?” Ocrevus carries a price tag of about $65,000 a year. That’s not high compared to some other MS drugs, but it still can mean a higher…

Ampyra is marketed as the only multiple sclerosis (MS) drug that is designed to increase an MS patient’s walking speed. Clinical studies show that patients who use the drug walk as much as 20 percent faster. Ampyra improved my speed, several years ago, when I was on…

Medicare spent more $650 million in 2013 and 2014 on one single medication — H.P. Acthar Gel —— that was prescribed by fewer than 1 percent of clinicians to treat multiple sclerosis (MS), with questionable results.

Ten years after completing treatment with Novantrone (mitoxantrone), a chemotherapy drug, multiple sclerosis (MS) patients showed evidence of markedly lower annualized relapse rates, but the therapy’s effects began to wane after five years, a study presented at ACTRIMS 2017 Forum reported. The study also assessed how Novantrone affects disease progression in primary and secondary progressive…

Tecfidera (dimethyl fumarate or DMF) use by multiple sclerosis (MS) patients can result in liver injury and, in rare cases, even severe injury, a study found, leading its researchers to recommend that patients’ on this treatment be carefully monitored for signs of injury. The study, “…

Two multiple sclerosis (MS) patients developed severe brain inflammation after being treated with Lemtrada (alemtuzumab), researchers report, raising questions about the therapy. A definite link between the lesions and the treatment, however, was not established.

Despite recent studies showing that treatment with Ampyra (Fampyra in Europe; fampridine) improves both walking speed and ability, and offers psychological benefits to patients with multiple sclerosis (MS), the Scottish Medicines Consortium (SMC) recently decided to not recommend the drug for use on the National Health Service (NHS) in Scotland.

Most of us who live with multiple sclerosis also live with a disease modifying therapy (DMT) — a drug that, we hope, will positively modify the course of our disease. One of the earliest of these was Avonex, a weekly injection into the muscle. I was one of those…

Mouse experiments with compounds having opposite actions on two receptors for TNF (tumor necrosis factor) — a key factor in neurodegeneration — explains why earlier trials of TNF blockers in multiple sclerosis (MS) went wrong, and paves the way for more selective drugs targeting the system to stop MS neurodegeneration. The…

The National Institute for Health and Care Excellence (NICE), the health authority for England and Wales, has decided not to recommend Zinbryta (daclizumab) be made available to multiple sclerosis (MS) patients through the country’s health service. The decision came in a first stage of the drug’s review process, and NICE is welcoming…
