Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with a documented diagnosis of multiple myeloma who have measurable disease and have received 1 to 3 prior lines of therapy.

Probably not a fit

Patients who have progressed during treatment with a proteasome inhibitor within the last 60 days may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness and safety of mezigdomide combined with bortezomib and dexamethasone (MeziVd) against a different combination of pomalidomide, bortezomib, and dexamethasone (PVd) in patients with relapsed or refractory multiple myeloma. Participants must have received 1 to 3 prior lines of therapy and have had previous exposure to lenalidomide. The study aims to determine which treatment combination provides better outcomes for patients with measurable disease.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment options for patients with relapsed or refractory multiple myeloma.

How similar studies have gone: Other studies have shown promising results with similar treatment combinations in multiple myeloma, indicating potential for success.

* Participants achieved minimal response \[MR\] or better to at least 1 prior antimyeloma therapy.

Exclusion Criteria

\- Participant has had progression during treatment or within 60 days of the last dose of a proteasome inhibitor, except as noted below:.

i) Subjects who progressed while being treated with, or within 60 days of last dose of bortezomib maintenance given once every 2 weeks (or less frequently) are not excluded.

ii) Participants who progressed while being treated with ixazomib monotherapy maintenance ≥ 6 months prior to the time of starting study treatment are not excluded.

* For participants with prior treatment of a bortezomib containing regimen, the best response achieved was not a minimal response (MR) or better, or participant discontinued bortezomib due to toxicity.
