Phase I, multicenter study to evaluate the safety, pharmacokinetics, pharmacodynamics and efficacy of HMPL-306 in Patients of Relapsed/Refractory Myeloid Leukemia/Neoplasms with IDH1 and/or IDH2 Mutation.
The purpose of this Phase I, multicenter study is to evaluate the safety, pharmacokinetics, pharmacodynamics and efficacy of HMPL-306 in Patients of Relapsed/Refractory Myeloid Leukemia/Neoplasms with IDH1 and/or IDH2 Mutation. The first stage of the study is a dose escalation phase where cohorts of patients will receive ascending oral doses of HMPL-306 to determine maximum tolerated dose (MTD) and/or the recommended Phase II dose. The second stage of the study is a dose expansion phase where three cohorts of patients will receive HMPL-306 to further evaluate the safety, tolerability, and clinical activity of the recommended Phase II dose.

HMPL-306 administered continuously as a single agent starting at 25 mg orally every day in a 28-day cycle and dose escalation is planned up to 200mg. Subjects may continue treatment with HMPL-306 until disease progression, development of other unacceptable toxicity or hematopoietic stem cell transplant.

Objective Response Rate (ORR)
proportion of patients with confirmed complete response (CR) and partial response (PR).
Time frame: Baseline up to the last patient has completed the 24 weeks of treatment
Duration of response (DOR)
DOR is defined as the time from the date of first observed tumor response (Complete response (CR) or Partial response (PR)) until first subsequent disease progression or until death (if death occurs before progression is documented) due to any cause.

Progression-free survival (PFS)
PFS is defined as the time from enrollment (i.e., date of treatment assignment) to disease progression.
Time frame: Baseline up to the last patient has completed the 24 weeks of treatment
Overall survival (OS)
OS is defined as the time from enrollment (i.e., date of treatment assignment) until death from any cause or until the last date the patient is known to be alive.
