The FDA also granted marketing authorization for a test to identify those patients eligible to receive olaparib: patients with an inherited, cancer-associated BRCA1 or BRCA2 (BRCA1/2) mutation.

AACR Annual Meeting 2017: Challenging the Dogma of Treating IDH-mutant Cancers With IDH Inhibitors

Two studies presented at the AACR Annual Meeting 2017 showed that tumors that have mutations in the proteins isocitrate dehydrogenase-1 or -2 (IDH1/2) exhibited features similar to that of BRCA-mutant tumors and are, therefore, more likely to respond better to PARP inhibitors than to IDH inhibitors.
