FDA OKs Roche’s Actemra for Giant Cell Arteritis
FDA has expanded the approved use of Hoffman La Roche’s subcutaneous Actemra (tocilizumab) to treat adults with giant cell arteritis. Giant cell arteritis is a form of vasculitis and it causes the arteries to narrow or become irregular, impeding adequate blood flow.
Approval was based on data from a 251-patient, placebo-controlled study. The primary efficacy endpoint was the proportion of patients achieving sustained remission from Week 12 through Week 52, according to an FDA release. “Sustained remission was defined as the absence of symptoms of giant cell arteritis, normalization of inflammatory laboratory tests, and tapering the use of prednisone (a steroid drug). A greater proportion of patients receiving subcutaneous Actemra with standardized prednisone regimens achieved sustained remission from Week 12 through Week 52 as compared to patients receiving placebo with standardized prednisone regimens. The cumulative prednisone dose was lower in treated patients with Actemra relative to placebo.”
Subcutaneous Actemra was previously approved for treating active rheumatoid arthritis. Intravenous Actemra was also previously approved for systemic juvenile idiopathic arthritis and polyarticular juvenile idiopathic arthritis. Intravenous administration is not approved for giant cell arteritis, FDA says.
