RecruitingDrug trialA Phase 1B/2A Trial of NADUNOLIMAB in Combination With Azacitidine (With/Without Venetoclax) in Patients With Myelodysplastic Syndrome (MDS) and Acute Myelogenous Leukemia (AML)To evaluate safety and determine the recommended Phase II dose (RP2D). We hypothesize that targeting leukemia stem/progenitor cells (LSCs) with nadunolimab (IL1RAP antibody) alone or in combination with current therapies of azacitidine (HMA) and venetoclax (Bcl-2 inhibitor), is an effective treatment strategy for high-risk MDS and AML, and with a clinical trial we will establish the safety and the early efficacy of this approach.
