Official title
A Phase 1 Study to Assess Safety and Tolerability of REGN5837, an Anti-CD22 x Anti-CD28 Costimulatory Bispecific Monoclonal Antibody, in Combination With Odronextamab, an Anti-CD20 x Anti-CD3 Bispecific Monoclonal Antibody, in Patients With Aggressive B-Cell Non-Hodgkin Lymphomas (ATHENA-1)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is researching an experimental drug called REGN5837 in combination with another drug, odronextamab (called "study drug\[s\]"), in patients with relapsed or refractory aggressive B-cell Non-Hodgkin Lymphomas (B-NHLs). The study has 2 parts. The aim of the first part (dose escalation) is to find a safe dose of REGN5837 when given in combination with odronextamab. The goal of the second part (dose expansion) is to use the REGN5837 drug dose found in the first part to see how well REGN5837 in combination with odronextamab works. The study is looking at several other research questions, including: * What side effects may happen from taking the study drugs * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drugs (that could make the drugs less effective or could lead to side effects)
