Multiple Myeloma Clinical Trial

A Study of an MMSET Inhibitor in Patients With Relapsed and Refractory Multiple Myeloma

Summary

A Phase I study to evaluate the safety of a novel, orally available, selective, and potent small molecule inhibitor of the histone lysine methyl transferase MMSET (also known as NSD2/WHSC1) to prevent the dimethylation of H3K36 in adult patients with relapsed or refractory multiple myeloma (RRMM).

View Full Description

Full Description

This is a Phase I, open-label, dose escalation and expansion study in adult patients with RRMM.

In the dose escalation phase (Part A), patients will be evaluated for DLTs during Cycle 1 (28 days). The KTX-1001 MTD, RP2D, and schedule will be determined.

In the dose expansion phase (Part B), patients with translocation t(4;14) or a GOF mutation in MMSET (eg, E1099K) will be enrolled. Patients will receive KTX-1001 at the RP2D to further define safety and tolerability and provide preliminary efficacy information.
