ABBV-744 ABBV-744 is a BDII-selective BET bromodomain inhibitor that inhibits BRD2, BRD3 and BRD4. It is developed for treating AML and cancers. In vitro
ABBV-744 is a potent inhibitor specific for BDII of BRD2/3/4, with >250-fold differential binding preference for BDII over BDI and excellent drug-like properties. ABBV-744 is also a potent and selective inhibitor of the AR (androgen receptor) transcription pathway.
In vivo
In vivo, doses of ABBV-744 at fractions of its maximum tolerated dose (MTD) induces tumor growth inhibition in AML and prostate cancer xenograft models that were comparable to those observed with ABBV-075 when dosed at its MTD. Cell Data
