A Phase I Study of Safety, Tolerability, Pharmacokinetic and Pharmacodynamics Property of Orally Administered APG-2575 in Patients With Hematologic Malignancies

Description

This is a multi-center, single-agent, open-label, Phase I study of APG-2575. The study consists of the dose escalation stage and the dose expansion stage.APG-2575 will be administered orally, once daily for consecutive 4 weeks as one cycles. Initially, the start dose is 20mg. Single patient cohorts will be evaluated, the dose of APG-2575 will be increased in subsequent cohorts, to 50 mg, 100 mg, 200 mg, 400 mg, 600mg and 800mg accordingly. If there is any one of the following event is observed, a DLT, two drug related Grade 2 toxicities or one drug related ≥ Grade 3 toxicity, or laboratory or clinical TLS, or suspected hypersensitivity reaction occur in Cycle 1, or dose level of 400 mg is reached, the dose escalation will convert to the standard 3+3 design, If ≥ 2/6 patients develop DLT at any dose level dose escalation will cease and the dose level immediately below will be expanded to 6 patients. If ≤ 1/6 patients develop a DLT at the highest dose reached this will be declared the MT
