Nemtabrutinib and Lisocabtagene Maraleucel for the Treatment of Relapsed/Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

Recruiting now · Phase 2

Conditions studied: Recurrent Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma, Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

In brief

This phase II trial studies how well the addition of nemtabrutinib to lisocabtagene maraleucel in treating patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Nemtabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lisocabtagene maraleucel is a type of treatment called chimeric antigen receptor (CAR) T-cell therapy, 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. Adding nemtabrutinib to lisocabtagene maraleucel may be an effective treatment for relapsed/refractory CLL/SLL.

• Absolute neutrophil count (ANC) ≥ 500/µL
• Growth factor and/or transfusion support is permissible to stabilize participant prior to study treatment if needed
• No lower limit if cytopenia is related to bone marrow involvement
• Hemoglobin ≥ 8 g/dL
• Growth factor and/or transfusion support is permissible to stabilize participant prior to study treatment if needed
• No lower limit if cytopenia is related to bone marrow involvement
• Platelets ≥ 25 000/µL
• Growth factor and/or transfusion support is permissible to stabilize participant prior to study treatment if needed
• No lower limit if cytopenia is related to bone marrow involvement
• Creatinine ≤ 1.5 × upper limit of normal (ULN) OR measured or calculated creatinine clearance (glomerular filtration rate [GFR] can also be used in place of creatinine or CrCl) ≥ 30 mL/min for participant with creatinine levels > 1.5 × institutional ULN
• Creatinine clearance (CrCl) should be calculated per institutional standard
• Total bilirubin ≤ 1.5 × ULN OR direct bilirubin ≤ ULN for participants with total bilirubin levels > 1.5 × ULN
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamic pyruvate transaminase [SGPT]) ≤ 2.5 × ULN (≤ 5 × ULN for participants with liver metastases)
• International normalized ratio (INR) OR prothrombin time (PT) ≤ 1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants

You may not qualify if…

• Diagnosis of Richter Transformation
• Clinically significant (symptomatic) central nervous system (CNS) involvement at time of study enrollment. Previously treated CNS disease is allowed if the participant is asymptomatic. Incidental findings including positive cerebral spinal fluid (CSF) studies are not exclusionary

• Active HBV/hepatitis C virus (HCV) infection
• Participants must have completed curative anti-viral therapy for HCV at least 4 weeks prior to study enrollment
• Participants who are HBsAg positive are eligible if they have received HBV antiviral therapy for at least 4 weeks and have undetectable HBV viral load prior to study enrollment
• Note: Participants should remain on anti-viral therapy throughout study intervention and follow local guidelines for HBV anti-viral therapy post completion of study intervention
• HIV with a detectable viral load or a CD4 count ≤ 350 cells/µL at time of screening
• Participants with HIV who do not meet the above criteria are eligible if they are on a stable antiretroviral therapy (ART) regimen (ART must not be strong CYP3A4 inducers) for at least 4 weeks prior to study entry and are compliant with ART are eligible
