Overview

This clinical trial is studying the safety and potential anti-tumor activity of an investigational drug called ARV-393 in patients diagnosed with advanced Relapsed/Refractory non-Hodgkin's lymphoma to determine if ARV-393 may be a possible treatment option.

ARV-393 is thought to work by breaking down a protein present in many types of non-Hodgkins lymphomas, which may prevent, slow or stop tumor growth. This is the first time ARV-393 will be used by people. The investigational drug will be given as an oral tablet.

• Participants must not have significant acute or chronic medical illness, including hypereosinophilic syndrome, active interstitial lung disease or pneumonitis, active or uncontrolled infection, or the presence of laboratory abnormalities, that places participants at unacceptable risk if participating in this study.
