Recruiting at 1 site Phase 1, Phase 2 Recurrent Multiple Myeloma

Clinical trial for Recurrent Multiple Myeloma

Official title Response-Based Dose Reduction of Linvoseltamab in the Treatment of Relapsed, Refractory, or Triple-Class Relapsed/Refractory Multiple Myeloma

ClinicalTrials.gov ID: NCT07181941

What this study is testing

What is Linvoseltamab?

Linvoseltamab is an investigational medicine, given as a once-weekly IV infusion (through a vein), being studied as a potential treatment for recurrent multiple myeloma.

Also referred to as Anti-BCMA x Anti-CD3 Bispecific Antibody REGN5458, Anti-BCMA/CD3 Bispecific Antibody REGN5458.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This phase I/II trial evaluates the safety and feasibility of early, response-based dose reduction of linvoseltamab in the treatment of patients multiple myeloma that has come back after a period of improvement (relapsed), that does not respond to treatment (refractory), or that is resistant to three classes of therapeutic agents, including proteasome inhibitors, immunomodulatory agents, and monoclonal antibodies (triple-class relapsed/refractory). Linvoseltamab is a bispecific antibody.
