FDA Priority Review for Genentech Actemra sBLA
FDA has accepted for priority review a Genentech supplemental BLA for Actemra (tocilizumab) for treating giant cell arteritis (GCA), a chronic, potentially life-threatening autoimmune condition. The submission is based on “positive outcome” data from a Phase 3 called GiACTA that evaluated Actemra in people with GCA, according to the company. “Results showed that Actemra, initially combined with a six-month steroid (glucocorticoid) regimen, more effectively sustained remission through one year compared to a six- or 12-month steroid taper regimen given alone in people with GCA,” it says.
GCA affects about 200 per 100,000 persons in the U.S. over the age of 50, and the disease is two to three times more likely to affect women than men, Genentech says. It is often difficult to diagnose because of the wide and variable spectrum of signs and symptoms. The condition causes severe headaches, jaw pain and visual symptoms and if left untreated, can lead to blindness, aortic aneurysm or stroke. Treatment to date for people with GCA has been limited to high-dose steroids as an “emergency” treatment option to prevent damage such as vision loss, the company says.
Actemra is a humanized interleukin-6 receptor antagonist approved for treating adult patients with moderately to severely active rheumatoid arthritis who have used one or more disease-modifying antirheumatic drugs, such as methotrexate, that did not provide enough relief.
