Summary

This trial is testing a combo of drugs to treat relapsed/refractory mantle cell lymphoma. It may help the body's immune system attack cancer and stop cancer cells from growing.

Who is the study for?

This trial is for adults with mantle cell lymphoma that has returned or didn't respond to previous treatments. Participants must be in fairly good health, have a certain level of blood counts and organ function, and agree to use effective birth control. People can't join if they've had certain recent cancer treatments, used T-cell engaging bispecific antibodies before, or been exposed to BTK inhibitors like ibrutinib.

What is being tested?

The trial tests the combination of acalabrutinib (a kinase inhibitor), obinutuzumab (a monoclonal antibody), and glofitamab (a bispecific antibody) on patients with relapsed/refractory mantle cell lymphoma. It aims to see how well these drugs work together and what side effects they might cause.

What are the potential side effects?

Potential side effects include reactions related to the immune system such as infusion reactions, low blood counts leading to increased infection risk or bleeding problems, liver enzyme changes suggesting liver impact, fatigue, and possibly heart issues due to the stress on the body's systems.

Experimental Treatment

Group I: Treatment (acalabrutinib, obinutuzumab, glofitamab)Experimental Treatment9 Interventions

Patients recieve acalabrutinib PO BID of each cycle, obinutuzumab IV on days 1 and 7 of cycle 1 only, and glofitamab IV over 2-4 hours on days 8 and 15 of cycle 1 and day 1 of each subsequent cycle. Treatment repeats every 21 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients with MRD positive CR, PR, or SD after 12 cycles of protocol therapy may continue receiving single agent acalabrutinib per standard of care during the follow-up phase of the study. Patients also undergo a ECHO or MUGA during screening, as well as PET/CT or CT, and blood specimen collection throughout the trial. Patients may also undergo bone marrow biopsies throughout the trial.
