Brief Summary

This phase IB/II trial tests the safety, side effects and effectiveness of glofitamab plus ibrutinib with obinutuzumab for the treatment of patients with mantle cell lymphoma (MCL). Glofitamab is in a class of medications called bispecific monoclonal antibodies. It works by killing cancer cells. 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). In the body, glofitamab binds to a receptor called CD3 on T-cells (a type of immune cells) and a receptor called CD20 on B-cells, a receptor that is often over-expressed on the surface of cancerous B-cells. When glofitamab binds to CD3 and CD20 receptors, it causes an immune response against the CD20-expressing cancerous B-cells. Ibrutinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells. Obinutuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Glofitamab plus ibrutinib with obinutuzumab may be safe tolerable and/or effective in treating patients with MCL.

Outcome Measures

Primary Outcomes (2)

  • Incidence of dose-limiting toxicities (DLT)

    The incidence and type of DLT will be reported. Descriptive statistics will be used to report AEs.

    At start of cycle 2 day 1 to end of Cycle 3 (each cycle is 21 days)

  • Proportion of participants who achieve a complete response (CR)

    The proportion of patients that achieve a CR will be reported with 95% exact confidence interval (CI). Response to treatment will be evaluated using positron emission tomography/computed tomography (CT) or CT studies and assessed according to Lugano criteria.

    Start of treatment (Cycle 1 Day 1) to date of first CR, documented at any on-treatment or end-of-treatment (EOT) disease assessment, up to 3 years

Secondary Outcomes (7)

  • Incidence of grade 3 or above adverse events (AEs)

    Cycle 1 Day 1 to 30 days after last dose of any study drug

  • Proportion of patients treated with tocilizumab (TCZ)

    Cycle 1 Day 1 to 30 days after last dose of glofitamab (Glt)

  • Number of doses of TCZ per participant

    Cycle 1 Day 1 to 30 days after last dose of Glt

  • Objective response rate (ORR)

    Cycle 1 Day 1 to date of first CR or partial response (PR), documented at any On Treatment or EOT disease assessment, up to 3 years

  • Progression-free survival (PFS)

    Cycle 1 Day 1 to first date of documented progression or death due to any cause, up to 3 years

  • +2 more secondary outcomes

Study Arms (1)

Treatment (glofitamab, ibrutinib, obinutuzumab)

EXPERIMENTAL

Patients receive ibrutinib PO QD on days 1-21 of cycles 1-17. Cycles repeat every 21 days for up to 17 cycles in the absence of disease progression or unacceptable toxicity. Patients receive glofitamab IV over 2-4 hours on days 8 and 15 of cycle 2 and then on day 1 of cycles 3-13. Cycles repeat every 21 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive obinutuzumab IV over 4 hours on cycle 2 day 1 and 2. Additionally, patients undergo echocardiography during screening, bone marrow biopsy on study, and CT scans, FDG PET/CT scans or MRI, and blood sample collection throughout the study.
