Biogen Inc. and Alkermes announced that the U.S. Food and Drug Administration (FDA) approved VUMERITY (diroximel fumarate), an oral fumarate with a distinct chemical structure, for the treatment of relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease and active secondary progressive disease. Biogen holds the exclusive, worldwide license to commercialize VUMERITY and intends to make it available in the U.S. in the near future.
“The approval of VUMERITY for relapsing MS marks the culmination of a multi-year development program and is the latest milestone in our mission to develop new treatments for patients living with chronic central nervous system disorders,” said Craig Hopkinson, M.D., chief medical officer and senior vice president of medicines development and medical affairs at Alkermes. “We are grateful to the patients and study investigators who have participated in our VUMERITY clinical trials and we look forward to working with our collaboration partners at Biogen to make this new treatment available to patients.”
The FDA approval of VUMERITY was based on a New Drug Application (NDA) submitted under the 505(b)(2) filing pathway. It included data from pharmacokinetic bridging studies comparing VUMERITY and TECFIDERA to establish bioequivalence, and relied, in part, on the FDA’s findings of safety and efficacy for TECFIDERA. The NDA submission also included interim exposure and safety findings from EVOLVE-MS-1, an ongoing, Phase 3, single-arm, open-label, two-year safety study evaluating VUMERITY in patients with relapsing-remitting MS. Interim results from EVOLVE-MS-1 at the time of NDA submission included a low overall rate of VUMERITY treatment discontinuation due to adverse events (6.3 percent), and a rate of less than one percent of patients who discontinued VUMERITY treatment due to gastrointestinal (GI) adverse events. Additional exploratory efficacy endpoints in the ongoing EVOLVE-MS-1 study showed changes in clinical and radiological measures compared to baseline.
“MS is a lifelong disease that has a significant impact on the people affected and their caregivers. We are encouraged by the progress being made in the treatment of MS and pleased that another treatment option will soon be available,” said Bruce Bebo, Ph.D., executive vice president, research, National MS Society. “It’s important for people with MS to have treatments that are both efficacious and tolerable to help manage their disease.”
Once in the body, VUMERITY rapidly converts to monomethyl fumarate, the same active metabolite of dimethyl fumarate. It is prescribed to adults. It is not known if VUMERITY is safe and effective in children.
