Study to Evaluate Tolerability of Iberdomide (CC-220) in Combination With Polatuzumab Vedotin Plus Rituximab or Tafasitamab or Rituximab Plus Chemotherapy in B-cell Lymphoma

A Phase 1B/2 Randomized, Multicenter, Open-Label Study Of Iberdomide (CC-220) In Combination With Polatuzumab Vedotin Plus Rituximab Or Tafasitamab Or Rituximab Plus Chemotherapy For Subjects With Relapsed Or Refractory Aggressive B-Cell Lymphoma

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.

Duration of Response (DOR)- Part 2	The time from the earliest date of documented response (≥ PR) to the first occurrence of relapse or progression.	Up to 7 years
Progression-free Survival (PFS)- Part 2	The time from entry to the study (enrollment date for Part 1 and randomization date for Part 2) to the first occurrence of disease progression or death from any cause.	Up to 7 years
Overall Survival (OS)- Part 2	The time from entry to the study (enrollment date for Part 1 and randomization date for Part 2) to death from any cause.	Up to 7 years
Pharmacokinetics (PK) - Cmax	Observed maximum CC-220 serum concentration	Up to 4 weeks
EORTC QLQ-C30 - Part 2	European Organization for Research and Treatment of Cancer - Quality of Life C30 questionnaire (EORTC QLQ-C30) consists of 30 questions incorporated into five functional domains (physical, role, cognitive, emotional, and social), nine symptom scales (fatigue, pain, nausea and vomiting, dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties), and a single global QoL/global health status score.	Up to 7 years
FACT-Lym LymS - Part 2	Functional Assessment of Cancer Therapy-Lymphoma Lymphoma subscale (FACT-Lym LymS) is a 15-item subscale that addresses health-related quality of life symptoms for Non-Hodgkin's lymphoma participants (eg, swelling, night sweats). The FACT instruments use a 5-point intensity type of rating scale (from "not at all" to "very much").	Up to 7 years
FACT/GOG-NTX-4 - Part 2	Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity 40-item questionnaire (FACT/GOG-NTX-4) is a 4-item peripheral neuropathy subscale used to differentiate between participants with and without treatment-related neurotoxicity. The FACT instruments use a 5-point intensity type of rating scale (from "not at all" to "very much").	Up to 7 years
