A Study of BL-M11D1 in Patients With Relapsed/Refractory Acute Myeloid Leukemia
A Phase I Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of BL-M11D1 in Relapsed/Refractory Acute Myeloid Leukemia (AML) Patients
Sichuan Baili Pharmaceutical Co., Ltd.
130 participants
Aug 2, 2023
INTERVENTIONAL
Conditions
Summary
Ia: To observe the safety and tolerability of BL-M11D1 in patients with relapsed/refractory acute myeloid leukemia to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of BL-M11D1. Ib: Further observe the safety and tolerability of BL-M11D1 at the recommended dose in phase Ia to determine the recommended dose in phase II clinical study (RP2D).
