A Study in Subjects With Relapsed/Refractory Multiple Myeloma and Relapsed/Refractory Diffuse Large B-Cell Lymphoma EZM0414

What's the purpose of this trial?

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).

This trial is currently open and accepting patients.

What will happen during the trial?

The first part of the study will be a Phase 1 dose-escalation designed to evaluate the safety, tolerability, and pharmacokinetics (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.
