Zanubrutinib and Lisocabtagene Maraleucel for the Treatment of Richter's Syndrome

Recurrent Transformed Chronic Lymphocytic Leukemia Clinical Trial

Official title: A Phase II Study Evaluating the Safety and Efficacy of the Combination of Zanubrutinib Plus Lisocabtagene Maraleucel for Richter's Syndrome

Status Recruiting

Clinical Trial Summary

This phase II trial tests how well zanubrutinib and lisocabtagene maraleucel (liso-cel) work together in treating patients with Richter's syndrome. Richter's syndrome occurs when chronic lymphocytic leukemia and/or small lymphocytic leukemia transforms into an aggressive lymphoma, which is a cancer of the lymph nodes. Zanubrutinib is a class of medication called a kinase inhibitor. These drugs work by preventing the action of abnormal proteins that tell cancer cells to multiply, which helps stop the spread of cancer. Liso-cel is a type of treatment known as chimeric antigen receptor (CAR) T cell therapy. CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Giving zanubrutinib and liso-cell together may kill more cancer cells in patients with Richter's syndrome.

Clinical Trial Description

PRIMARY OBJECTIVE:

I. To evaluate the efficacy of the combination of zanubrutinib and lisocabtagene maraleucel (liso-cel) for the treatment of Richter's syndrome (RS).

SECONDARY OBJECTIVES:

I. To describe the safety profile of the combination of zanubrutinib and liso-cel for RS.

II. To evaluate duration of the efficacy of the combination of zanubrutinib and liso-cel for RS

CORRELATIVE OBJECTIVES:

I. Describe T-cell subsets before and after zanubrutinib initiation, as well as post liso-cel infusion.

II. To describe the persistence of liso-cel. III. To describe the tumor microenvironment post liso-cel infusion at relapse. IV. Investigate the correlation between inflammatory cytokines and measures of inflammation and outcomes and rates of adverse events including cytokine release syndrome (CRS).

V. Investigate chronic lymphocytic leukemia (CLL) persistence post treatment.

OUTLINE:

Patients receive zanubrutinib orally (PO), undergo leukaphereis, and receive fludarabine intravenously (IV), cyclophosphamide IV, and liso-cel IV on study. Patients also undergo bone marrow (BM) biopsy and lymph node biopsy at screening and follow up, and undergo collection of blood samples and computed tomography (CT), positron emission tomography (PET)/CT, and/or magnetic resonance imaging (MRI) throughout the trial.

After study completion, patients are followed for 24 months, and then every 6 months until disease progression or death. ;
