OTX015 is a novel, highly potent, selective and cell permeable inhibitor of the bromodomain and extra terminal (BET) family proteins BRD2, BRD3 and BRD4 with IC50 of 10-19 nM. It inhibits the growth of a variety of human cancer cell lines with IC50 ranging from 60 to 200 nM. OTX015 results in rapid down-regulation of c-MYC expression, and show the synergistic anti-proliferative effects in combination with ALK inhibitors in ALKpos ALCL cell lines. In vivo studies using OTX015 have demonstrated efficacy in a range of oncology models. OTX015 is currently in phase I clinical development for oncology indication.
How to Use:
In vitro: OTX015 was used at 2-10 μM final concentration in various in vitro assays.
In vivo: OTX015 could be dosed to the mice by oral administration at 100 mg/kg once per day or 10 mg/kg twice per day.
