FDA approves FoundationOneCDx as a companion diagnostic for Lynparza

Foundation Medicine, Inc. announced it has received approval from the FDA for FoundationOneCDx to be used as a companion diagnostic for Lynparza (Olaparib) for first line maintenance therapy in BRCA-mutated advanced ovarian cancer. FoundationOne CDx is an FDA-approved comprehensive genomic profiling (CGP) test for all solid tumors that incorporates multiple companion diagnostics. FoundationOne CDx detects tumor BRCA1 and BRCA2 mutations including both germline (inherited) and somatic (acquired) mutations.

FoundationOne CDx may help identify more women who could benefit from Lynparza as compared to conventional testing methods that only identify germline BRCA mutations. Germline-only BRCA1/2 testing identifies approximately half of all BRCA1/2 mutations.

In December of 2018, AstraZeneca and Merck & Co., Inc. announced that the FDA approved Lynparza for use as maintenance treatment of adult patients with deleterious or suspected deleterious germline or somatic BRCA-mutated (gBRCAm or sBRCAm) advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response to 1st-line platinum-based chemotherapy.
