Genentech Triple Combo OK’d for Melanoma
FDA has approved a Genentech supplemental BLA for its triple combination of Tecentriq (atezolizumab) plus Cotellic (cobimetinib) and Zelboraf (vemurafenib) for treating BRAF V600 mutation-positive advanced melanoma patients. The agency’s review was conducted under Project Orbis, an FDA Oncology Center of Excellence program that provides a framework for concurrent submission and review of oncology products among international partners. Approval is based on data from the Phase 3 IMspire150 study, in which the addition of Tecentriq to Cotellic and Zelboraf helped people live longer without their disease worsening or death, compared to placebo plus Cotellic and Zelboraf (median progression-free survival 15.1 months versus 10.6 months respectively). The most common adverse reactions (rate greater than 20%) in patients who received Tecentriq plus Cotellic and Zelboraf were rash (75%), musculoskeletal pain (62%), fatigue (51%), hepatotoxicity (50%), pyrexia (49%), nausea (30%), pruritus (26%), edema (26%), stomatitis (23%), hypothyroidism (22%), and photosensitivity reaction (21%).
