Brief summary

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.

Detailed description

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.

Interventions

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.

Secondary

MeasureTime frameDescription
Cmax (Cycle 1 Day 1) of HMPL-306Pre-dose, 10 minutes, 1, 1.5, 2, 3, 5, 8, 11, 24, 48, 72, 120 and 168 hours after startCmax: maximum observed drug concentration in measured matrix after single dose administration.
AUC(0-24) (Cycle 1 Day 1) of HMPL-306Pre-dose, 10 minutes, 1, 1.5, 2, 3, 5, 8, 11, 24, 48, 72, 120 and 168 hours after startAUC: area under the concentration vs. time curve from zero to infinity after single (first) dose.
AUC(0-tlast) (Cycle 1 Day 1) of HMPL-306Pre-dose, 10 minutes, 1, 1.5, 2, 3, 5, 8, 11, 24, 48, 72, 120 and 168 hours after startAUC from time zero to the last data point.
Objective Response Rate (ORR)Baseline up to the last patient has completed the 24 weeks of treatmentproportion of patients with confirmed complete response (CR) and partial response (PR).
Duration of response (DOR)Baseline up to the last patient has completed the 24 weeks of treatmentDOR 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)Baseline up to the last patient has completed the 24 weeks of treatmentPFS is defined as the time from enrollment (i.e., date of treatment assignment) to disease progression.
Overall survival (OS)Baseline up to the last patient has completed the 24 weeks of treatmentOS 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.
