The study is researching an experimental drug called REGN5837 in combination with another experimental drug, odronextamab (called "study drugs"). The aim of the study is to see how safe and tolerable the study drugs are, and to define the recommended dose for phase 2. 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) * To find out how well the study drugs work against relapsed or refractory aggressive B-cell non-Hodgkin lymphomas (B-NHLs)
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Regeneron Pharmaceuticals (REGN) is the sponsoring company for this trial. BiotechSign currently grades this company D (47/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
