On Sept. 13, 2024, Genentech announced  that the U.S. Food and Drug Administration (FDA) had approved Ocrevus Zunovo™ (ocrelizumab & hyaluronidase-ocsq) for the treatment of relapsing multiple sclerosis (RMS) and primary progressive multiple sclerosis (PPMS).

Ocrevus Zunovo is the first and only twice-a-year, healthcare professional (HCP)-administered approximately 10-minute subcutaneous (SC) injection approved for both these forms of multiple sclerosis, giving people living with MS more treatment options.

After the first dose, the time for treatment with Ocrevus Zunovo could be as little as 55 minutes. Patients will be required to take premedications at least 30 minutes prior to each dose. Following the first dose, patients will be monitored by their HCP for at least 60 minutes. Patients will be monitored for at least 15 minutes post-injection for subsequent doses.

The FDA approval is based on pivotal data from the Phase III OCARINA II trial, which showed no clinically significant difference in the levels of Ocrevus in the blood when administered subcutaneously, and a safety and efficacy profile consistent to the IV formulation in people with RMS and PPMS.

Out of the exploratory outcomes measured, Ocrevus Zunovo was consistent with IV, demonstrating suppression of relapse activity (97%) and MRI lesions (97%) through 48 weeks. Additionally, one of several patient-reported outcomes measured during the study showed more than 92% of trial participants reported being satisfied or very satisfied with the SC administration of Ocrevus Zunovo.
