A Phase 2 Study of Glofitamab With Acalabrutinib in Patients With Relapsed/Refractory Mantle Cell Lymphoma
City of Hope Medical Center
Summary
This phase II trial studies the side effects of acalabrutinib, obinutuzumab, and glofitamab and how well they work together for 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). Acalabrutinib is in a class of medications called kinase inhibitors. It blocks a protein called BTK, which is present on B-cell (a type of white blood cells) cancers such as mantel cell lymphoma at abnormal levels. This may help keep cancer cells from growing and spreading. 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). Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of cancer cells to grow and spread. Glofitamab is a class of medications called bispecific antibodies. Bispecific antibodies are designed to simultaneously bind to T cells and cancer cell antigens, leading to T-cell activation, proliferation, and cancer cell death. Giving acalabrutinib, obinutuzumab, and glofitamab together may be a safe and effective treatment for patients with relapsed or refractory mantle cell lymphoma.
Description
PRIMARY OBJECTIVES: I. Evaluate the safety and tolerability of a regimen combining acalabrutinib and glofitamab in patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL). (Safety Lead-In) II. Estimate the complete response (CR) rate in R/R MCL patients treated with acalabrutinib plus glofitamab. (Phase 2) SECONDARY OBJECTIVES: I. Estimate the minimal residual disease (MRD) negativity rate, time to response, duration of response (DOR), progression-free survival (PFS), overall survival (OS), and patient-reported quality of life measures (HRQOL) in R/R MCL patients treated with aca…
