Plain-language summary
This phase II trial tests the safety and side effects of glofitamab and obinutuzumab and how well they work in treating patients with mantle cell lymphoma that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory) after receiving CD19-directed chimeric antigen receptor (CAR) T-cell therapy. CAR T-cell therapy is a form of immunotherapy where the immune system cell, T-cell, is changed to attack cancer cells. Glofitamab is a bispecific antibody that can bind to two different antigens at the same time. Glofitamab binds to CD3, a protein found on T cells (a type of white blood cell), and CD20 a protein found on B cells (another type of white blood cell) and some lymphoma cells. This may help the immune system kill cancer cells. Obinutuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Giving glofitamab and obinutuzumab may be safe, tolerable, and/or effective in treating patients with relapsed or refractory mantle cell lymphoma after receiving CD19-directed CAR T-cell therapy.

Inclusion Criteria:
* Patients must have histologically or cytologically confirmed diagnosis of mantle cell lymphoma that is relapsed (disease progression after the last treatment regimen) or refractory (failure to achieve a partial or complete response from the last treatment regimen)
* Patients must have been previously treated with an anti-CD19 CAR T-cell therapy and have failed or been intolerant to Bruton's tyrosine kinase (BTK) inhibition. Both commercial and investigational CAR-T products which target CD19 will be allowed, including dual-targeting products
* Patients must have at least one bi-dimensionally measurable (defined as at least 1.5 cm) nodal lesion or one bi-dimensionally measurable (at least 1 cm) extranodal lesion, as measured on CT scan
* Age ≥ 18 years. Because no dosing or adverse event (AE) data are currently available on the use of glofitamab and obinutuzumab in patients \< 18 years of age, children are excluded from this study
* Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (Karnofsky ≥ 60%)
* Absolute neutrophil count ≥ 1,000/mcL
* Platelets ≥ 50,000/mcL
* Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN) or ≤ 3 x institutional ULN if the patient has Gilbert syndrome
* Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT)(serum glutamic pyruvic transaminase \[SGPT\]) ≤ 3 x institutional ULN
* Creatinine ≤ 1.5 x institutional ULN OR glomerular filtration ra…
