This Phase 1 study will look at different doses and different treatment schedules in order to better understand the effects of the combined regimens on the newly diagnosed or refractory/relapsed adult participants with AML ,MDS or CMML. The procedures include screening for eligibility, study treatments, and blood & bone marrow tests. All the safety events will be record, pharmacokinetic parameters (Tmax, Cmax,T1/2, AUC et al.) will be calculated, response and survival will be assess during the study. Participants will be treated indefinitely until disease progression, unacceptable toxicity or withdrawal for other reasons.
This is a Phase 1, open-label, multicenter, dose-escalation & expansion study to evaluate the safety,tolerability and pharmacokinetics (PK) of LP-108, a BCL-2 inhibitor, combined with azacitidine, to determine the dose limiting toxicity (DLT) and the recommended Phase 2 dose (RP2D), and to assess the preliminary efficacy of this combination.
