Study Description

Brief 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.

Outcome Measures

Primary Outcome Measures

Maximum Tolerated Dose (MTD) [During the First cycle (each cycle is 28 days)]
Frequency of dose limiting toxicities (DLT) to define MTD of CC- 220 in combination with polatuzumab vedotin plus rituximab or tafasitamab or rituximab plus chemotherapy in subjects with R/R a-BCL.
Recommended Phase 2 Dose (RP2D) [During the First cycle (each cycle is 28 days)]
Frequency of dose limiting toxicities (DLT) to establish the RP2D of CC- 220 in combination with polatuzumab vedotin plus rituximab or tafasitamab or rituximab plus chemotherapy in subjects with R/R a-BCL.
Best Overall Response Rate (ORR) [Up to 7 years]
The proportion of participants with best overall response achieved during the study as either Complete Response or Partial Response before subsequent anti-lymphoma therapy.

Secondary Outcome Measures

Incidence of Adverse Events (AEs) [From enrollment until at least 28 days after last dose of study treatment]
An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participant during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the participant's health, including laboratory test values regardless of etiology. Any worsening (ie, any clinically significant adverse change in the frequency or intensity of a preexisting condition) should be considered an AE.
Best ORR- Part 1 [Up to 6 years]
The proportion of participants with best overall response achieved during the study as either Complete Response or Partial Response before subsequent anti-lymphoma therapy.
Complete Response Rate (CRR)- Part 2 [Up to 7 years]
The proportion of participants experiencing Complete Response before receiving any subsequent anti-lymphoma therapy.
Time to Response (TRR)- Part 2 [Up to 7 years]
The time from entry to the study (enrollment date for Part 1 and randomization date for Part 2) to the date of first documented response (≥ PR).
Duration of Response (DOR)- Part 2 [Up to 7 years]
The time from the earliest date of documented response (≥ PR) to the first occurrence of relapse or progression.
Progression-free Survival (PFS)- Part 2 [Up to 7 years]
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.
Overall Survival (OS)- Part 2 [Up to 7 years]
The time from entry to the study (enrollment date for Part 1 and randomization date for Part 2) to death from any cause.
Pharmacokinetics (PK) - Cmax [Up to 4 weeks]
Observed maximum CC-220 serum concentration
EORTC QLQ-C30 - Part 2 [Up to 7 years]
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.
FACT-Lym LymS - Part 2 [Up to 7 years]
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").
FACT/GOG-NTX-4 - Part 2 [Up to 7 years]
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").
EQ-5D-5L - Part 2 [Up to 7 years]
EQ-5D-5L has 2 components: a descriptive system and a visual analogue scale (VAS). The instrument's descriptive system consists of 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.
