Study Details
Study Description
Brief Summary
A Phase I, Open-label, Dose-escalation Study of the Safety and Pharmacokinetics of HMPL-523 in Patients With Relapsed or Refractory Mature B-cell Neoplasms
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1 |
Detailed Description
There are two stages in this study: a dose-escalation stage (stage 1) and a dose-expansion stage (stage 2).
Dose-escalation stage (stage 1):
The conventional 3+3 design (3 patients per dose cohort, with the potential to add additional 3 patients to the same cohort to further evaluate toxicity) will be applied for dose escalation and maximum tolerated dosage determination. Approximately 27 to 42 dose limited toxicities evaluable patients will be enrolled. The actual number of patients depends on the dose limited toxicities situation as well as the maximum tolerated dosage reached at this stage.
Dosing will begin at 200mg once daily. A cycle of study treatment will be defined as 28 days of continuous dosing.
Dose-expansion stage (stage 2):
This phase is to further evaluate the safety, the pharmacokinetics and anti-tumor activity of HMPL-523 at recommended phase 2 dosage in approximately 190 patients with relapsed or refractory Hematologic Malignancies.
In this stage, approximately 190 patients with Mature B-cell Neoplasms will be enrolled with recommended phase 2 dosage 600milligram(mg) one a day(QD) as starting dosing. The tumor types of the expansion stage are restricted to Chronic lymphocytic leukemia/ small lymphocytic lymphoma (CLL/SLL), Mantle cell lymphoma (MCL), Follicular Lymphoma (FL), Diffuse large B-cell lymphoma (DLBCL), Marginal zone lymphoma (MZL)and Waldenstrom's macroglobulinemia (WM)/Lymphoplasmacytic lymphoma(LPL) Subjects will receive HMPL-523 with every 28-day treatment cycle until disease progression, death, or intolerable toxicity, whichever comes first.

Outcome Measures
Primary Outcome Measures
- Dose limited toxicities evaluated with NCI CTCAE v4.03 [within 28 days after the first dose]
Incidence of dose limited toxicities and associated dose of HMPL-523
Secondary Outcome Measures
- Maximum plasma concentration calculated with Blood samples [within 29 days after the first dose]
Blood samples will be taken to measure the levels of study drug
- Time to reach maximum concentration calculated with Blood samples [within 29 days after the first dose]
Blood samples will be taken to measure the levels of study drug
- Objective response rate [within 30 days after the last dose]
the proportion of subjects who have a Complete Response or Partial Response
- Adverse events evaluated by NCI CTCAE v4.03 [from the first dose to within 30 days after the last dose]
Incidence of adverse events and associated dose of HMPL-523
