Phase 1 Study of 6MW5311 in Adults With Relapsed or Refractory Blood Cancers
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).
Tutkimuksen yleiskatsaus
Yksityiskohtainen kuvaus
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.

Kokeellinen: Part 1 - Dose Escalation (6MW5311)
A modified 3+3 design with accelerated titration will be used to evaluate planned dose levels. |
A bispecific T cell engager (TCE) antibody: bivalent binding to LILRB4 on tumor cells and monovalent binding to CD3 on T cells. |
|
Kokeellinen: Part 2 - Dose Expansion (6MW5311)
Participants with chronic myelomonocytic leukemia (CMML), multiple myeloma (MM), or relapsed or refractory acute myeloid leukemia (AML; acute myelomonocytic or monocytic subtypes) will receive 6MW5311 at the dose level(s) selected by the Safety Review Committee from Part 1. |
