Study to Assess the Safety and Tolerability of CFT7455 in Relapsed/Refractory Non-Hodgkin's Lymphoma or Multiple Myeloma
Purpose
The purpose of this study is to characterize the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of oral cemsidomide (also known as CFT7455) administered at different dosages in subjects with Relapsed/Refractory (r/r) Non-Hodgkin's Lymphoma (NHL) or Multiple Myeloma (MM). Cemsidomide may be administered as a single agent and, in MM only, in combination with oral dexamethasone.

A male subject must agree to use a condom when having intercourse with a person of child bearing potential during the treatment period and for at least 30 days after the last dose of study treatment. 10. Males must refrain from donating sperm during the treatment period and for 30 days after the last dose of study treatment. 11. Subjects must refrain from donating blood during study treatment and for 30 days after discontinuation.
