therapy.

Key exclusion criteria
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 are not excluded.

- For participants with prior treatment of a bortezomib containing regimen, the best

Summary
Brief summary
The purpose of this study is to compare the efficacy and safety of mezigdomide (CC-92480),

in participants with relapsed or refractory multiple myeloma (RRMM) who received between 1 to
3 prior lines of therapy and who have had prior lenalidomide exposure.
