FDA approves Genentech’s Ocrevus for relapsing and primary progressive forms of MS

An important new treatment option for people with relapsing forms of multiple sclerosis demonstrating superior efficacy on the three major markers of disease activity compared with Rebif.

“The FDA’s approval of OCREVUS is the beginning of a new era for the MS community and represents a significant scientific advance with this first-in-class B cell targeted therapy,” said Sandra Horning, chief medical officer and head of Global Product Development. “Until now, no FDA-approved treatment has been available to the primary progressive MS community, and some people with relapsing forms of MS continue to experience disease activity and disability progression despite available therapies. We believe OCREVUS, given every six months, has the potential to change the disease course for people with MS, and we are committed to helping those who can benefit gain access to our medicine.”

In two identical RMS Phase III studies (OPERA I and OPERA II), Ocrevus demonstrated superior efficacy on the three major markers of disease activity by reducing relapses per year by nearly half, slowing the worsening of disability and significantly reducing MRI lesions compared with Rebif (high-dose interferon beta-1a) over the two-year controlled treatment period. A similar proportion of people in the Ocrevus group experienced a low rate of serious adverse events and serious infections compared with people in the high-dose interferon beta-1a group in the RMS studies.

In a separate PPMS Phase III study (ORATORIO), Ocrevus was the first and only treatment to significantly slow disability progression and reduce signs of disease activity in the brain (MRI lesions) compared with placebo with a median follow-up of three years. A similar proportion of people in the Ocrevus group experienced adverse events and a low rate of serious adverse events compared with people in the placebo group in the PPMS study.

The most common side effects associated with Ocevus in all Phase III studies included infusion reactions and upper respiratory tract infections, which were mostly mild to moderate in severity. Results from these three Phase III studies were recently published in the January 19, 2017 issue of the New England Journal of Medicine.

“This is an exciting day for everyone touched by MS, a disease that strikes in the prime of a person’s life when she or he may be starting a career or family,” said June Halper, CEO at the Consortium for MS Centers. “We have eagerly awaited the FDA approval of Ocrevus because it not only offers a new, highly efficacious treatment option for people with relapsing multiple sclerosis, but it is also the first disease-modifying therapy indicated for primary progressive multiple sclerosis, a highly disabling type of this chronic disease. For many people living with MS, this FDA approval is a source of hope.”

Ocrevus will be available to people in the US within 2 weeks.

The Ocrevus Marketing Authorization Application has also been validated by the European Medicines Agency and is currently under review.
