New Ocrevus Findings Show Benefits to Range of MS Patients: Interview with Genentech’s Dr. Hideki Garren
Genentech shared new insights into the workings of Ocrevus (ocrelizumab) and its effectiveness in reducing disease activity and slowing progression in relapsing and primary progressive multiple sclerosis (MS) at the recent 3rd Congress of the European Academy of Neurology (EAN). The new findings, previously reported here, built on analyses of information gathered during the three Phase 3 clinical trials assessing Ocrevus' safety and efficacy, as well as through monitoring patients in extension studies. The studies showed that nearly 40 percent of Ocrevus-treated relapsing patients and nearly 30 percent of primary progressive patients achieved NEPAD during the Phase 3 trials. In contrast, only 21.5 percent of those treated with Rebif and 9.4 percent receiving placebo achieved NEPAD — figures that demonstrate Ocrevus’ impact on patients’ lives, as well as Ocrevus’ ability to slow the decline in walking ability and other types of disabilities are comparable between patients with relapsing and primary progressive disease — data that demonstrate that the treatment acts on disease mechanisms that drive disability in both disease forms. How these effects play out in the long-term is the subject of ongoing research, as Genentech continues to follow these patients in an extension study. In addition, Ocrevus' prescription label strongly advises against pregnancy while on the treatment. Despite precautions, some women became pregnant during the trials. One of the meeting presentations narrated outcomes of these pregnancies; one healthy baby born at term and two ongoing pregnancies in women exposed to the drug. But while Genentech monitors women who become pregnant while on Ocrevus, the number of reported pregnancies is too small to draw conclusions about the treatment’s safety in pregnancy, and researchers do not know if Ocrevus also depletes B-cells in the fetus or in the baby born to a treated woman.
