Description: BI-894999 is a potent and selective BET inhibitor potentially useful for the Treatment of hematological malignancies by repression of super-enhancer driven oncogenes. BI-894999 is a highly potent drug, particularly in hematological cell lines (n>40) such as MM, AML and lymphoma. BI 894999 treatment leads to G1 arrest and subsequent apoptosis. BI 894999 is found to regulate a very distinct set of genes. As already known.

Biological target: BI 894999 is a BET inhibitor with IC50s of 5 nM and 41 nM for the binding of BRD4-BD1 and BRD4-BD2 to acetylated histones, respectively.
In vitro activity: Treatment of MV-4-11B cells with BI 894999 for 72 h led to induction of a G1 arrest with an increase in cells in sub-G1, indicative for apoptosis (Suppl. Figure 2). Significant inhibition of proliferation was observed at concentrations of 10 nM BI 894999. Dose-dependent apoptosis peaked at around 40 h after the start of treatment (Suppl. Figure 3A, B).

In vivo activity: For in vivo studies, BI 894999 was administered at daily oral doses of 2 or 4 mg/kg to mice engrafted intravenously with human MV-4-11B AML cells (Suppl. Table 5). This treatment resulted in tumor growth inhibition (TGI) of 96 or 99% and survival prolongation of 29.5 or 52 days, respectively (Fig. 2a).
