Business objectives have changed.

This Phase 1/2, multicenter, open-label study to evaluate CC-220 alone, as well as in combination with an anti-CD20 mAb (rituximab or obinutuzumab) in subjects with relapsed or refractory (R/R) lymphoma. Subjects must have received at least 2 prior lines of therapy, and have at least one measurable lesion according to Lugano 2014 classification.

Study will consist of two parts: Part 1 (Dose Escalation) which will be followed by Part 2 (Dose Expansion).

   4. Cohort D: aggressive B-cell lymphoma and FL grade 1-3a
   5. Cohort E: aggressive B-cell lymphoma including DLBCL NOS, high-grade B-cell lymphoma, with MYC and BCL2 and/or BCL6 rearrangements, Grade 3b FL and PMBCL
   6. Cohorts F and G: FL Grade 1 to 3a

3. Relapsed or refractory disease according to the following definitions:

   2. Follicular lymphoma (FL) and Marginal zone lymphoma (MZL): following at least 2 prior lines of systemic therapy (being previously exposed to at least 1 anti-CD20 mAb and 1 alkylating agent).
   3. Mantle cell lymphoma (MCL): following at least 2 prior lines of therapy including at least 1 immunochemotherapy and 1 bruton tyrosine kinase (BTK) inhibitor.
   4. Peripheral T-cell lymphoma (PTCL): following at least 2 prior lines of therapy OR after 1 prior line of standard therapy and being not eligible for any other approved regimen.
   5. Classical Hodgkin lymphoma (cHL): following at least 2 prior systemic lines of therapy and previously exposed to brentuximab vedotin and anti-PD1.
   6. All other subtypes: following at least 2 prior lines of therapy.
   7. Subjects previously treated with CAR-T therapy can be enrolled (irrespective of the indication).

4. Subjects must not be eligible for any other approved treatment for their underlying lymphoma as assessed by the Investigator.

5. Must have measurable disease defined by at least 1 fluorodeoxyglucose (FDG)-avid lesion for FDG-avid subtype and 1 bi-dimensionally measurable (> 1.5 cm in longest diameter) disease by computed tomography (CT) or magnetic resonance imaging (MRI), as defined by the Lugano classification. Site of measurable disease cannot be previously irradiated.

6. Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2.

7. Must have the following laboratory values:

   1. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L or ≥ 1.0 x 109/L
   2. Hemoglobin (Hb) ≥ 8 g/dL.
   3. Platelets (Plt) ≥ 75 x 109/L or ≥ 50 x 109/L
   4. Aspartate aminotransferase / serum glutamic oxaloacetic transaminase (AST/SGOT) and alanine aminotransferase / serum glutamic pyruvic transaminase (ALT/SGPT) ≤ 2.5 x ULN.
   5. Serum total bilirubin ≤ 1.5 ULN except in cases of Gilbert's syndrome, then ≤ 3.0 ULN.
   6. Estimated serum creatinine clearance of ≥ 50 mL/min

8. All subjects must:

   1. Have an understanding that the study drug could have a potential teratogenic risk.
   2. Agree to follow all requirements defined in the Pregnancy Prevention Program for CC-220 Pregnancy Prevention Plan for Subjects in Clinical Trials.

9. Females of childbearing potential (FCBP1) must:

   a. Have 2 negative pregnancy tests as verified by the Investigator prior to starting study treatment. She must agree to ongoing pregnancy testing during the course of the study, and after end of study treatment.

10. Male subjects must:

    1. Practice true abstinence2 or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study,

Exclusion Criteria:

The presence of any of the following will exclude a subject from enrollment:

1. Any significant medical condition, active infection (including severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2) suspected or confirmed, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study.

2. Any condition including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study.

3. Life expectancy ≤ 3 months.

4. Diagnosis of lymphoblastic lymphoma.

5. Aggressive lymphoma relapse requiring immediate cytoreductive therapy to avoid potential life-threatening consequences (eg, due to tumor location).

6. Prior Grade 3 or 4 infusion related reaction with rituximab (for Cohorts B, E and F) or obinutuzumab (for Cohorts C and G).

7. Prior therapy with the cereblon-modulating drug CC-99282.
