Study Details

Study Description

Brief Summary

This is a phase 1, open-label, dose-escalation study of fimepinostat (CUDC-907) in patients with relapsed and/or refractory diffuse large B-cell lymphoma (DLBCL), or high-grade B-cell lymphoma (HGBL) with or without MYC and BCL2 alterations. Fimepinostat (CUDC-907) is a multi-targeted agent designed to inhibit phosphoinositide 3-kinase (PI3K)and histone deacetylase (HDAC). The study is designed to assess the safety, the maximum tolerated dose, the recommended phase 2 dose (RP2D), pharmacokinetics and the anti-cancer activity of oral fimepinostat in combination with 1 or more anti-cancer regimens.
