Phase 1 Study of 6MW5311 in Adults With Relapsed or Refractory Blood Cancers

2026年10月27日 更新者：Mabwell (Shanghai) Bioscience Co., Ltd.

A Phase 1, Safety, Pharmacokinetic, Immunogenicity, and Preliminary Efficacy Study of 6MW5311 in Relapsed/Refractory Acute Myeloid Leukemia (AML) Patients, in Chronic Myelomonocytic Leukemia (CMML) Patients and Multiple Myeloma (MM) Patients

To assess safety and tolerability at increasing dose levels of 6MW5311 in successive cohorts of participants with MM, AML and CMML in order to estimate the maximum tolerated dose (MTD) and select the recommended Phase 2 dose (RP2D) or the recommended expansion dose (RED).

详细说明

This is a 2-part, open-label, multicenter, First-in-Human Phase 1 clinical trial consisting of dose escalation (Part 1) and dose expansion (Part 2). Part 1 will evaluate the safety and tolerability, immunogenicity, PK/PD, biomarker, and preliminary clinical activities of 6MW5311. Part 2 will select appropriate dose(s) for expansion based on preliminary efficacy, safety, immunogenicity, PK/PD, and biomarkers data from Part 1, and will further assess the safety, PK, biomarker, and efficacy of 6MW5311. Upon completion of the Phase 1 clinical trial and findings from non-clinical studies, the recommended expansion dose (RED) or recommended Phase 2 dose (RP2D) of 6MW5311 in patients with hematological malignancies will be determined.

措施说明
大体时间
Number of participants with dose-limiting toxicities (DLTs)
大体时间：From the first dose of Cycle 1 through Day 28 of Cycle 1 (each cycle is 28 days)

DLTs are adverse events considered related to 6MW5311 (definitely, probably, or possibly related) that occur during the dose-limiting toxicity observation period (first 28 days after the first dose of Cycle 1). DLTs are defined per the protocol and graded per the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 6.0.
