Study to Assess the Safety and Tolerability of CFT7455 in Relapsed/Refractory Non-Hodgkin's Lymphoma or Multiple Myeloma CFT7455

What's the purpose of this trial?

The purpose of this study is to characterize the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of CFT7455 administered orally in subjects with Relapsed/Refractory (r/r) Non-Hodgkin's Lymphoma (NHL) or Multiple Myeloma (MM) administered once a day (QD) as a single agent and in combination with dexamethasone (in MM patients only).

This trial is currently open and accepting patients.
