Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥18 years at the time of signing Informed Consent
• ECOG 0-2
• Histologic diagnosis confirmed as relapsed/refractory mantle cell lymphoma according to WHO guidelines, confirmed by the pathology department at the treating institution
• If the patient previously received CD20 directed therapy, there must be evidence of CD20 expression on neoplastic cells according to instutitional pathology department guidelines. This must be confirmed on a biopsy of Relapsed/Refractory Mantle Cell Lymphoma performed after receipt of the last CD20 directed therapy.
• At minimum 10 unstained slides or tissue block from tumor containing FFPE biospecimen sample from a Relapsed/Refractory Mantle Cell Lymphoma biopsy is required for tumor genomic profiling and MRD testing. If adequate archival tissue is not available, then a repeat biopsy will be required. This requirement can be waived (i.e. if site of disease is inaccessible) after discussion with the MSKCC Principal Investigator
• Tumor genomic profiling from a biopsy sample collected within 6 months of signing informed consent form is required. For MSK patients, this will be done via MSK IRB#12-245 (Integrated Mutation Profiling of Actionable Cancer Targets (IMPACT)) within 6 months prior to signing Informed Consent form, and preferably repeated for patients who did not have IMPACT performed after discontinuing their last line of treatment. Patients at external sites will run genomic profiling per institutional guidelines. If sites do not have an approved assay available, they may send archival tissue to MSK. Details included in lab manual
• Previously treated with at least one prior line of systemic therapy for mantle cell lymphoma. Prior BTKi failure is required. BTKi failure is defined as progression of disease during BTKi therapy or patients must have progressed or relapsed after completing BTK inhibitor therapy, or failed to achieve a PR following 12 weeks of BTK inhibitor therapy.
• Presence of evaluable disease
• Adequate bone marrow and organ function:
• Absolute neutrophil count (ANC) ≥1,000 cells/mcL, unless felt to be secondary to underlying MCL (minimum ANC 500 cells/mcL)
• Hgb ≥ 8 g/dL without transfusional support for 7 days before first treatment, unless felt to be secondary to underlying MCL (minimum Hgb 7.0 g/dL) without transfusional support for 7 days before first treatment)
• Platelet count ≥50,000 cells/mcL without transfusional support for 7 days before first treatment, unless felt to be secondary to underlying MCL (minimum platelet count 25,000 cells/mcL) without transfusional support for 7 days before first treatment)
• Renal function assessed by calculated Cockcroft-Gault creatinine clearance (CrCl; see Appendix A) ≥ 30 ml/min. See lenalidomide Treatment Plan, (Table 10-1), for lenalidomide dose adjustment for CrCl ≥ 30 mL/min and < 60 mL/min
• Adequate hepatic function as determined by:
• Total bilirubin ≤1.5X upper limit of normal (ULN) unless secondary to Gilbert's syndrome or documented liver involvement by lymphoma. Patients with Gilbert's syndrome or documented liver involvement by lymphoma may be included if their total bilirubin is ≤ 5 x ULN
• Aspartate aminotransferase (AST, SGOT) and alanine aminotransferase (ALT, SGPT) ≤ 3 x ULN or ≤ 5 x ULN in cases of documented liver involvement.
• Willingness to receive adequate prophylaxis and/or therapy for thromboembolic events, unless contraindicated in the opinion of the investigator.
• Willingness to undergo confirmatory procedures for assessment of disease status and experimental studies as required by protocol, including bone marrow (BM) aspiration/biopsy and gastrointestinal endoscopy/colonoscopy with biopsy, and/or biopsy of other tissue when appropriate and medically feasible.
• Each patient must sign an informed consent form indicating that he or she understands the purpose of and procedures required for the study and are willing to participate.Patients with impaired decision-making capacity (IDMC) who have a legally authorized representative (LAR) or caregiver and/or family member available will also be eligible.
• Willingness of patients who can become pregnant, according to Revlimid/lenalidomide Risk Evaluation and Mitigation Strategy (REMS) criteria, to undergo pregnancy testing in accordance with REMS requirements
• Willingness of all patients to complete surveys and adhere to contraception requirements mandated by the Revlimid/lenalidomide REMS
• For women of childbearing potential: Agreement to remain abstinent (refrain from heterosexual intercourse) or use two adequate methods of contraception, including at least one method with a failure rate of <1% per year, for at least 28 days prior to Day 1 of Cycle 1, during the treatment period (including periods of treatment interruption), and for at least 2 months after the final dose of glofitamab, 28 days after the last dose of lenalidomide, 18 months after the last dose of obinutuzumab.
• For men: Agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures and agreement to refrain from donating sperm, as defined below: With female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 2 months after the final dose of glofitamab, 28 days after last dose of lenalidomide, 6 months after the last dose of obinutuzumab. Men must refrain from donating sperm during this same period.
• Life expectancy ≥ 12 weeks as determined by patient's primary clinician

You may not qualify if…

• 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. (Prophylactic anti-viral treatment is required for subjects who are HBV core antibody positive)
• 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

• 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.

• 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
