PRIMARY OBJECTIVE:
I. To evaluate the end of induction (EOI) complete response rate (CR) for treatment with the regimen of rituximab and hyaluronidase human + polatuzumab vedotin + venetoclax (RSC + Pola + Ven) in relapsed/refractory mantle cell lymphoma (MCL).
SECONDARY OBJECTIVES:
I. To evaluate the EOI overall response rate (ORR) for the combination of RSC + Pola + Ven in relapsed/refractory MCL.
II. To evaluate the best response (CR, partial response [PR]) in patients who continue on to maintenance therapy and evaluate the improvement in the depth of response.
III. To evaluate the progression free survival (PFS) and overall survival (OS) for the combination of RSC + Pola + Ven) in relapsed/ refractory MCL.
IV. To compare the ORR, CR, PFS, and OS in ibrutinib refractory compared to ibrutinib naive patients.
V. To evaluate regimen-related toxicity for patients treated with RSC + Pola + Ven.
CORRELATIVE RESEARCH OBJECTIVES:
I. To evaluate changes in minimal residual disease (MRD) status in both responding and non-responding patients at EOI and end of maintenance and compared to baseline as well as correlate MRD status with PFS and OS.
II. To evaluate changes in systemic immune profiles and T cell activation induced by treatment with RituxSC (RSC) + Pola + Ven.
III. To evaluate the prognostic importance of high risk cytogenetic alterations, and other risk stratification scores in patients with relapsed/refractory MCL receiving RituxSC + Pola + Ven.

- Complete response (CR) rate [ Time Frame: At Study Completion, up to 5 years from registration ]Objective status of CR measured by positron emission tomography (PET)-computed tomography (CT) scans according to Lugano 2014.
- Overall response rate (ORR) [ Time Frame: At Study Completion, up to 5 years from registration ]The ORR at the end of induction will be estimated by the total number of patients who achieve a complete response (CR) or partial response (PR) by PET-CT scans according to Lugano 2014 divided by the total number of evaluable patients. The ORR between ibrutinib-naive and ibrutinib-pretreated patients will be compared using Fisher's exact test.
- Best response rate to maintenance therapy [ Time Frame: At Study Completion, up to 5 years from registration ]CR, PR, and stable disease (SD) rates for patients who continue to maintenance will be estimated by number of patients who continue on maintenance therapy and achieve CR, PR or SD, respectively, at the end of maintenance divided by the total number of evaluable patients who continue to maintenance.
- Progression free survival (PFS) [ Time Frame: From registration to the earliest date of documentation of disease progression by CT or PET/CT or death due to any cause, assessed up to 5 years ]The distribution of PFS will be estimated using the method of Kaplan-Meier. The PFS between ibrutinib-naive and ibrutinib-pretreated patients will be compared using log-rank test.
- Overall survival (OS) [ Time Frame: From registration to death due to any cause, assessed up to 5 years ]The distribution of OS will be estimated using the method of Kaplan-Meier. The OS between ibrutinib-naive and ibrutinib-pretreated patients will be compared using log-rank test.
- Incidence of adverse events (AEs) [ Time Frame: Up to 5 years ]All AEs occurring on or after first study treatment will be summarized by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 grade.
- Minimal residual disease (MRD) analysis [ Time Frame: At Study Completion, up to 5 years from registration ]MRD status for both responders and non-responders at each time point will be reported descriptively, and explored for correlation with clinical factors and patient outcomes such as PFS and OS.
- T cell subset analysis [ Time Frame: At Study Completion, up to 5 years from registration ]T cell activation will be investigated using multi-parameter flow cytometry.
- Cytokine subset analysis [ Time Frame: At Study Completion, up to 5 years from registration ]Systemic immune profiles will be investigated using cytokine analysis in the peripheral blood of patients.
- High risk cytogenetic alterations [ Time Frame: At Study Completion, up to 5 years from registration ]Will be summarized using frequency and percentages.
- Risk stratification scores [ Time Frame: At Study Completion, up to 5 years from registration ]Will be summarized using frequency and percentages.
