Study Summary

SLS009 (formerly GFH009) is a potent and highly selective CDK9 inhibitor. In this study the safety, tolerability, and antitumor activity of single agent SLS009 are assessed in two dose escalation groups (Group 1 in patients with relapsed/refractory AML, Group 2 in patients with relapse/refractory lymphoma/CLL/SLL). The safety, tolerability, and antitumor activity of SLS009 in combination with venetoclax and azacitidine in patient with relapsed/refractory AML who have relapsed on or are refractory to venetoclax-based regimens are being assessed in five cohorts of the expansion Group 3. Groups 4 and 5 have been added to evaluate efficacy, safety, and tolerability of GFH009 in combination with venetoclax and azacitidine in newly diagnosed AML patients who are less likely to benefit from standard induction treatment with venetoclax plus HMA only regimens.
