This trial will seek to extend the preliminary findings of efficacy of MBG453 in combination with hypomethylating agents (HMA) by evaluating MBG453 in combination with the HMA azacitidine and the Bcl-2 inhibitor venetoclax.

Official Title

A Phase II Multi-center, Single Arm, Safety and Efficacy Study of MBG453 in Combination With Azacitidine and Venetoclax for the Treatment of Acute Myeloid Leukemia (AML) in Adult Patients Unfit for Chemotherapy


The purpose of the current study is to assess clinical effects of MBG453 in combination with hypomethylating agents (HMA) (azacitidine or decitabine) in adult subjects with International Prognostic Scoring System (IPSS-R) intermediate, high, very high risk MDS. The primary purpose of Part 1 (Safety Run-in) is to rule out excessive toxicity of MBG453, when administered in combination with azacitidine and venetoclax. The primary purpose of the combined Part 1 and Part 2 (Safety run-in and Expansion Part) is to evaluate efficacy of MBG453, when administered in combination with azacitidine and venetoclax in adult patients with newly diagnosed AML, who are not suitable for treatment with intensive chemotherapy. There will be one analysis of the CR rate, 7 months after the last randomized subject. PFS will not be tested at this time point. A maximum of two analyses will be performed for PFS. A PFS interim analysis will be scheduled when approximately 81 PFS events (after 75% of the planned target PFS events with an option to stop for efficacy) have been documented, expected to occur approximately 28 months after the first subject randomized. If PFS is not statistically significant at the IA, the study will continue until the final PFS analysis. The final PFS analysis will be performed after observing approximately 108 PFS events (or at the latest at 4 years after the last subject is randomized) expected to occur approximately 51 months after the first subject randomized.
