Genentech’s Ocrevus Zunovo Approved for MS
FDA has approved Genentech’s Ocrevus Zunovo (ocrelizumab and hyaluronidase-ocsq) twice-a-year subcutaneous injection for treating relapsing multiple sclerosis and primary progressive multiple sclerosis. “Ocrevus Zunovo gives patients and providers another option for receiving Ocrevus, building on a decade of robust safety and efficacy data for Ocrevus in multiple sclerosis,” the company says.
Approval is based on data from the Phase 3 OCARINA II trial, which showed no clinically significant difference in the levels of Ocrevus in the blood when administered subcutaneously. It also showed a safety and efficacy profile consistent to the currently approved intravenous (IV) formulation. “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,” according to the company.
Ocrevus Zunovo is described as combining Ocrevus with Halozyme Therapeutics’ Enhanze drug delivery technology. The monoclonal antibody is designed to target CD20-positive B cells, a specific type of immune cell thought to be a key contributor to myelin (nerve cell insulation and support) and axonal (nerve cell) damage, Genentech says. “Based on preclinical studies, Ocrevus binds to CD20 cell surface proteins expressed on certain B cells, but not on stem cells or plasma cells, suggesting that important functions of the immune system may be preserved,” it adds.
