Clovis receives Breakthrough Therapy Designation for Rubraca
Clovis Oncology announced that the U.S. Food and Drug Administration has granted Breakthrough Therapy designation for Rubraca as a monotherapy treatment of adult patients with BRCA1/2-mutated mCRPC who have received at least one prior androgen receptor-directed therapy and taxane-based chemotherapy. Breakthrough Therapy designation is granted by the FDA to investigational agents intended to treat a serious or life-threatening disease or condition and whose preliminary clinical evidence may demonstrate substantial improvement on at least one clinically significant endpoint over available therapy. The FDA previously granted Breakthrough Therapy designation to Rubraca for the monotherapy treatment of certain advanced ovarian cancer patients and then in December 2016 approved Rubraca for the treatment of certain adult patients with deleterious BRCA mutation associated epithelial ovarian, fallopian tube, or primary peritoneal cancer who have been treated with two or more chemotherapies. The FDA subsequently approved Rubraca in a second indication, the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy, in April 2018. This most recent Breakthrough Therapy designation was granted to Rubraca based on initial efficacy and safety results from TRITON2, the Phase 2 study of Rubraca in men with advanced prostate cancer with BRCA 1/2 mutations and deleterious mutations of other homologous recombination repair genes, in the metastatic castration-resistant setting.
