A Study in Subjects With Relapsed/Refractory Multiple Myeloma and Relapsed/Refractory Diffuse Large B-Cell Lymphoma
Study Details
Study Description
Brief Summary
This is a first-in-human (FIH), 2-part, open-label, multi-center, Phase 1/1b safety, tolerability, pharmacokinetics (PK), and efficacy study of oral SETD2 inhibitor, EZM0414, in subjects with relapsed/refractory (R/R) Multiple Myeloma (MM) and R/R Diffuse Large B-Cell Lymphoma (DLBCL).

Phase 1 |
Detailed Description
The first part of the study will be a Phase 1 dose-escalation designed to evaluate the safety, tolerability, and PK of EZM0414 in subjects with R/R MM and R/R DLBCL. Six dose levels starting at 100 mg, then 200 mg, 300 mg, 400 mg, 600 mg, and 900 mg as well as an optional step-down dose of 75 mg (if needed) will be tested. The second part of the study is the Phase 1b dose expansion at the MTD designed to evaluate safety and efficacy in subjects with R/R DLBCL and R/R MM with or without select genetic translocation. Dose expansion will enroll subjects in 3 cohorts: Cohort 1 for R/R MM subjects with t(4;14), Cohort 2 for R/R MM subjects without t(4;14), and Cohort 3 for subjects with R/R DLBCL.

Outcome Measures
Primary Outcome Measures
- Number of participants with treatment-emergent adverse events as assessed by CTCAE v5.0 [Through study completion, an average of 3 years]
Severity of adverse events experienced by all subjects with at least 1 dose or partial dose of EZM0414 and DLT (Dose Limiting Toxicity) will be evaluated by the Investigator based on the CTCAE, version 5.0
- Establishing Maximum Tolerated Dose (MTD) and a recommended Phase 2 Dose (RP2D) [Through study completion, an average of 3 years]
Determine MTD and select a dose for further evaluation in phase 2 (RP2D)
- Efficacy of EZM0414 as demonstrated by the effect on objective response rate (ORR) in subjects with R/R MM and R/R DLBCL [Through study completion, an average of 3 years]
ORR defined as the proportion of responders as assessed by Investigator per IMWG 2016 guidelines for MM or Lugano 2014 guidelines for DLBCL
