Phase 3 Study Comparing Odronextamab Plus Lenalidomide Versus Rituximab Plus Lenalidomide in Adults With Relapsed or Refractory Follicular and Marginal Zone Lymphoma

What this Trial Is About

Researchers are evaluating an experimental drug called odronextamab combined with lenalidomide in adults who have relapsed or refractory follicular lymphoma FL or marginal zone lymphoma MZL, which are subtypes of Non-Hodgkins lymphoma. The study aims to assess the safety, tolerability, and proper dosing of this new combination and compare its effectiveness to the current standard treatment of rituximab combined with lenalidomide. The research also explores side effects, drug levels in the blood, immune responses to the drug, and impacts on quality of life and daily functioning. The study has two parts Part 1 is a safety phase where all participants receive odronextamab plus lenalidomide to determine the appropriate dose. Part 2 is randomized and compares two groupsone receiving odronextamab with lenalidomide, and the other receiving rituximab with lenalidomide followed by lenalidomide alone. Participants receive these treatments according to the study protocol during these phases. Throughout the study, participants will undergo various assessments including safety monitoring for side effects, measurement of drug concentrations and immune responses, imaging scans to evaluate disease status, and quality-of-life questionnaires. The primary outcomes include tracking dose-limiting toxicities up to 35 days and treatment-emergent adverse events up to 2 years. Longer-term outcomes such as progression-free survival and overall survival will be followed for up to 5 years, with ongoing evaluations to understand the treatments impact over time.
