Men must refrain from donating sperm during this same period. * Life expectancy ≥ 12 weeks as determined by patient's primary clinician

Exclusion criteria

* Investigational agent or anticancer therapy within 5 half-lives prior to start of study therapy except therapeutic monoclonal antibody treatment must be discontinued a minimum of 4 weeks prior to study therapy. An exception is BTKi therapy, which can be continued to prevent disease flare up until 1 day prior to start of study therapy. * Major surgery within 4 weeks prior to planned start of study therapy. * Radiotherapy within 7 days of the start of study therapy. * CART infusion within 30 days prior to Day 1 of Cycle 1 * Active hepatitis B or C, as defined below: * HBV surface antigen positive * HBV surface antigen negative, HBV core antibody positive and detectable HBV viral DNA. Note: subjects who are HBV core antibody positive and viral DNA negative are eligible. * HCV antibody positive and HCV RNA positive. * History of human immunodeficiency virus (HIV) unless all of the following criteria are met: * CD4+ T cell count ≥ 250 cells/mcL * No acquired immunodeficiency syndrome (AIDS)-defining opportunistic infections within 1 year prior to signing Informed Consent Form * Stable (no change in regimen for ≥ 4 weeks) and effective antiretroviral regimen, and HIV viral load \< 400 copies/mL within 4 weeks prior to signing Informed Consent form * Active concurrent malignancy requiring active therapy within the last 3 years with the exception of basal cell carcinoma limited to the skin, squamous cell carcinoma limited to the skin, carcinoma in situ of the cervix or breast, adequately treated lentigo maligna melanoma, or localized prostate cancer. Adjuvant or maintenance therapy to reduce the risk of recurrence of other malignancy previously treated for curative intent is permitted. * Pregnant or lactating, intending to become pregnant, or unable/unwilling to comply with pregnancy testing and birth control measures and REMS enrollment, as described in inclusion criteria. * Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) at study enrollment, or any major episode of infection requiring treatment with IV antibiotics or hospitalization (relating to the completion of the course of antibiotics) within 4 weeks prior to cycle 1, day 1. * Clinically significant history of liver disease, including active viral or other hepatitis or current uncontrolled alcohol use disorder that would compromise patient's ability to safely participate in the trial, per clinician's judgment * Active central nervous system (CNS) involvement with lymphoma, either parenchymal or leptomeningeal * Presence of ≥Grade 2 toxicity (CTCAE v5.0) due to prior cancer therapy * History of severe allergic or anaphylactic reactions to monoclonal antibody therapy (or recombinant antibody-related fusion proteins) * Patient with history of confirmed progressive multifocal leukoencephalopathy (PML) * History of hypersensitivity to compounds of similar biological or chemical composition to IMiDs® and/or the excipients contained in the study drug formulations * Previous treatment with bispecific antibody therapy directed against CD20 and CD3 * Previous treatment with lenalidomide or other IMiDs® within 12 months of treatment initiation on this study. * Documented refractoriness to lenalidomide, defined as no response (PR or CR) within 6 months of therapy * Autologous stem cell transplantation (ASCT) within the period ≤3 months prior to the signing of the informed consent form.

When clinically indicatedfeasible, tumor assessments such as imaging and biopsies should be performed prior to steroid administration, though this is not required for enrollment. * Chronic corticosteroid use of ≤20 mg prednisone equivalent per day, on a stable dose for ≥4 weeks prior to registration. * Any life-threatening illness, medical condition, or organ system dysfunction that, in the opinion of the investigator, could compromise the subject's safety, or affect compliance with the protocol or interpretation of results. * Evidence of any significant, uncontrolled concomitant disease that could affect compliance with the protocol or interpretation of results, including significant cardiovascular disease (such as New York Heart Association Class III or IV or Objective Assessment Class C or D cardiac disease, myocardial infarction ≤ 6 months from registration, symptomatic congestive heart failure, unstable arrhythmia, or unstable angina) or significant pulmonary disease (such as obstructive pulmonary disease or history of bronchospasm)
