About this study
Official title: A Phase 1 Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of LP-108, a BCL-2 Inhibitor, Combined With Azacitidine In Subjects With AML, MDS, CMML
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.
Read the detailed description
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum Tolerated Dose(MTD)
Standard phase I 3+3 design. The first 3 subjects will be assigned to dose level 1 cohort. If none of the first three subjects experiences DLT, escalation to dose level 2 cohort is permitted. If one of the first three subjects' experiences DLT, a total of six subjects will be required in that dose cohort, and escalation will only be permitted if five of six subjects do not experience DLT. If more than one DLT is observed in the dose level 2 cohort, this will be determined to be the maximally administered dose, and three more subjects will be enrolled in the dose level 1 cohort if only three were previously treated at that dose. Escalation from dose level 2 to level 3 cohort will be with the same method as before. The MTD will be the cohort in which ≤1/6 subjects have dose limiting toxicity at the dose prior to the maximally administered dose. If the dose level 3 cohort has ≤1/6 subjects with a DLT, the MTD will not have been reached.
Measured: Up to 42 days after initial dose of study drug at the designated cohort dose.
Recommended Phase 2 Dose(RP2D)
RP2D will be determined using available safety and pharmacokinetics data upon completion of the dose escalation phase.
Measured: Up to 1.5 years
Incidence of AEs
Type, frequency and severity of AEs, relationship of AEs to study treatment
Measured: From first dose of study drug to 28 days after last dose of study drug
Incidence of clinically significant changes in clinical laboratory results

Cmax of LP-108

Measured: Up to 24 hours post dose
Tmax of LP-108
Time to maximum plasma concentration (Tmax) of LP-108.
Measured: Up to 24 hours post dose
