This phase II trial studies how well bendamustine, obinutuzumab, and venetoclax work in treating patients with mantle cell lymphoma. Drugs used in chemotherapy, such as bendamustine and venetoclax, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving bendamustine, obinutuzumab, and venetoclax may work better in treating patients with mantle cell lymphoma.


I. To evaluate the efficacy of the combination of bendamustine, obinutuzumab and venetoclax in patients with untreated mantle cell lymphoma.

I. To evaluate the safety and dose intensity of the combination of bendamustine, obinutuzumab and venetoclax in untreated mantle cell lymphoma.
II. To explore methods of determining molecular remission for patients with untreated mantle cell lymphoma (MCL).
III. To evaluate long-term outcomes including progression-free and overall survival for patients with untreated MCL who receive the combination.

Patients receive venetoclax orally (PO) on days 1-28 of course 1 and days 1-10 of subsequent courses, bendamustine intravenously (IV) on days 1 and 2, and obinutuzumab IV on days 1, 8, and 15 of course 1 and day 1 of subsequent courses. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unaccepted toxicity.

After completion of study treatment, patients are followed up at 45-60 days.
