Clinical Trial Summary

This is a Phase 1b/2 randomized study of Iberdomide (CC-220) added to 3 different combination regimens (polatuzumab vedotin plus rituximab (Cohort A), tafasitamab (Cohort B), rituximab plus gemcitabine and platinum-based chemotherapy (Cohort C)) for participants with relapsed or refractory aggressive B-cell lymphoma (R/R a-BCL). All 3 cohorts will be open for enrollment at study start. Part 1 (dose escalation) will be followed by Part 2 (dose expansion), in which participants will be randomized to one of three cohorts, with CC-220 at the recommended Phase 2 Dose in combination with the Cohorts A, B and C treatment that is compared to their individual standard of care regimen.
