Olaparib in treatment‐refractory isocitrate dehydrogenase 1 (IDH1)– and IDH2‐mutant cholangiocarcinoma: Safety and antitumor activity from the phase 2 National Cancer Institute 10129 trial

Abstract Background Neomorphic isocitrate dehydrogenase (IDH) mutations lead to the accumulation of 2-hydroxyglutarate (2-HG), an oncometabolite implicated in tumor progression via inhibitory effects on alpha-ketoglutarate. Moreover, mutant IDH–dependent accumulation of 2-HG results in homologous recombination deficiency (HRD), which preclinically renders tumors sensitive to poly(adenosine diphosphate ribose) polymerase inhibitors. Here, the results of the cholangiocarcinoma (CCA)… Continue reading Olaparib in treatment‐refractory isocitrate dehydrogenase 1 (IDH1)– and IDH2‐mutant cholangiocarcinoma: Safety and antitumor activity from the phase 2 National Cancer Institute 10129 trial

Olaparib as treatment for platinum‐sensitive relapsed ovarian cancer by BRCA mutation and homologous recombination deficiency: Phase 2 LIGHT study final overall survival analysis

Abstract Background LIGHT (oLaparib In HRD-Grouped Tumor types; NCT02983799) prospectively evaluated olaparib treatment in patients with platinum-sensitive relapsed ovarian cancer (PSROC) assigned to cohorts by known BRCA mutation (BRCAm) and homologous recombination deficiency (HRD) status: germline BRCAm (gBRCAm), somatic BRCAm (sBRCAm), HRD-positive non-BRCAm, and HRD-negative. At the primary analysis, olaparib treatment demonstrated activity across all… Continue reading Olaparib as treatment for platinum‐sensitive relapsed ovarian cancer by BRCA mutation and homologous recombination deficiency: Phase 2 LIGHT study final overall survival analysis
