What this trial studies

This Phase 1/2 interventional trial administers mRNA-2808 to participants with relapsed or refractory multiple myeloma to define safety, tolerability, and an appropriate dose. Eligible patients must have prior exposure to a proteasome inhibitor, an immunomodulatory drug, and an anti-CD38 monoclonal antibody and must meet measurable disease criteria. The protocol includes early-phase dose-escalation followed by expansion cohorts to collect preliminary activity and safety data. Participants will be followed at study centers with regular clinic visits, labs, and imaging as required to monitor adverse events and signs of response.

Who should consider this trial

Good fit: Adults with relapsed or refractory multiple myeloma who have prior exposure to a proteasome inhibitor, an IMiD, and an anti-CD38 antibody and who meet the study's measurable disease criteria are ideal candidates.

Not a fit: Patients with CNS myeloma, active plasma cell leukemia, or those who received recent cytotoxic therapy or disallowed immunotherapies are excluded and would not be expected to benefit from participation.

Why it matters

Potential benefit: If successful, this therapy could provide a new treatment option that helps control disease in patients whose myeloma no longer responds to current therapies.

How similar studies have performed: mRNA-based cancer immunotherapies are a relatively new approach with encouraging early results in some cancers but limited published evidence specifically in multiple myeloma.
