Summary
Brief summary
This is a Phase 1/2 study of imvotamab in adult subjects with relapsed or refractory B-cell Non-Hodgkin Lymphoma. This study will consist of a dose-escalation stage, a combination stage, and a randomized dose-expansion stage where subjects will be enrolled into indication-specific expansion cohorts. imvotamab will be administered intravenously (IV).

Additional CD20-positive NHL histologies (e.g. MZL and MCL), may be allowed with Medical Monitor approval during the Dose-Escalation Phase of the study.
