  6. Participant must have the following laboratory values:

     1. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L or ≥ 1.0 x 109/L in case of documented bone marrow involvement (> 50% or tumor cells), without growth factor support for 7 days (14 days if pegylated granulocyte-colony stimulating factor (peg-G-CSF))
     2. Hemoglobin ≥ 8 g/dL

     5. Serum total bilirubin ≤ 2.0 mg/dL (34 μmol/L) except in cases of Gilbert syndrome, then ≤ 5.0 mg/dL (86 μmol/L)
     6. Estimated serum creatinine clearance of ≥ 50 mL/minute using the modification of diet in renal disease formula.

  7. All participants 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 Participants in Clinical Trials.

  8. A female of childbearing potential (FCBP) must:

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

  9. Male participants must:

     1. Practice true abstinence (which must be reviewed on a monthly basis and source documented) 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 participant from enrollment:

  1. Participant has any significant medical condition, active infection (including SARS-CoV-2 suspected or confirmed), laboratory abnormality, or psychiatric illness that would prevent the participant from participating in the study.

     a. In the case of prior SARS-CoV-2 infection, symptoms must have completely resolved

  2. Participant has any condition including the presence of laboratory abnormalities, which places the participant at unacceptable risk if he/she were to participate in the study.
  3. Participant has any other subtype of lymphoma.
  4. Participant has received systemic anti-cancer treatment, CAR-T or any T-cell targeting treatment (approved or investigational) ≤ 5 half-lives or 4 weeks prior to starting CC-220, whichever is shorter.
  5. Participant has received prior therapy with a Cereblon-modulating drug (eg, lenalidomide, avadomide) ≤ 4 weeks prior to starting CC-220.
  6. Participant has persistent diarrhea or malabsorption ≥ Grade 2 (NCI-CTCAE v5.0), despite medical management.
  7. Participant has peripheral neuropathy ≥ Grade 2 (NCI CTCAE v5.0).
  8. Participant is on chronic systemic immunosuppressive therapy or corticosteroids.
  9. Participant has impaired cardiac function or clinically significant cardiac disease.
  10. Participant had major surgery ≤ 2 weeks prior to starting CC-220.
