Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals with a confirmed diagnosis of relapsed or refractory multiple myeloma who have not responded to multiple prior therapies.
✕Probably not a fit
Patients with conditions such as monoclonal gammopathy of undetermined significance or those who have had recent stem cell transplants may not benefit from this study.

What this trial studies
This Phase 1b open-label study evaluates the safety and tolerability of OPN-6602, both as a standalone treatment and in combination with dexamethasone, for patients with relapsed and/or refractory multiple myeloma. The study will also assess the pharmacokinetics, preliminary antitumor activity, and pharmacodynamics of the treatment. Participants will be closely monitored to determine the effectiveness and safety of the drug regimen over the course of the trial.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat multiple myeloma.
How similar studies have gone: Other studies exploring similar treatment approaches have shown promise, but this specific combination is being evaluated for the first time.
