Study of SLS009 (Formerly GFH009) a Potent Highly Selective CDK9 Inhibitor in Patients With Hematologic Malignancies and High-Risk Newly Diagnosed AML (NCT04588922)

A Phase I/IIa, Open-Label Dose Escalation and Dose Expansion Study of Intravenous GFH009 Single Agent and in Combination With Venetoclax and Azacitidine in Patients With Relapsed/Refractory Hematologic Malignancies and High-Risk Newly Diagnosed AML

๐ŸŸข Recruiting Phase1 / Phase2 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Sellas Life Sciences Group

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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.
