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.

Inclusion Criteria \- Participant has documented diagnosis of MM and measurable disease, defined as any of the following:. i) M-protein ≥ 0.5 grams per deciliter (g/dL) by serum protein electrophoresis (sPEP) or. ii) M-protein ≥ 200 milligrams (mg) per 24-hour urine collection by urine protein electrophoresis (uPEP). iii) For participants without measurable disease in sPEP or uPEP: serum free light chain (sFLC) levels \> 100 mg/L (10 mg/dL) involved light chain and an abnormal kappa/lambda FLC ratio. * Participants received 1 to 3 prior lines of antimyeloma therapy. * 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. * Participant has had prior treatment with mezigdomide or pomalidomide. * Other protocol-defined Inclusion/Exclusion criteria apply.
