ARID1A mutation sensitizes most ovarian clear cell carcinomas to BET inhibitors
They used the pan-BET inhibitors JQ1 (not in clinical trials) and iBET762 (in clinical trials as GSK525762). Zenith was already planning a ZEN-3694 + PARP inhibitor trial (outlined in BIO Europe March 2018 timeline slide) in Homologous recombination deficiency (HRD) patients with ovarian, prostate or breast cancer. Perhaps this recent finding gives them another subset of ovarian cancers to focus on too. Thanks to Aureus over on IV for posting. However, not sure if RVX-208/apabetalone would work for this since it is a bromodomain-2 selective compound, not a pan-BET inhibitor like JQ1, iBET762 and ZEN-3694.
