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
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.

If cytopenias are due to disease in the bone marrow any degree of anemia or thrombocytopenia are allowed - Radiographically measurable lymphadenopathy (or measurable extra-nodal disease) per Lugano criteria - Must meet all institutional standards for receiving CAR T-cell therapy - Subjects (or legal guardians) must have the ability to understand and the willingness to sign a written informed consent document - For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of < 1% per year, initiated prior to first dose of study drug, during the treatment period and for at least 1 year after the CAR-T cell infusion or 1 month after last dose of zanubrutinib, whichever is longer. - A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (< 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices - For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below: - With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for at least 1 year after the anti-CD19 CAR-T cell infusion or 1 month after last dose of zanubrutinib, whichever is longer. Men should avoid fathering a child and refrain from donating sperm during this same period. - With pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 1 year after the human anti- CD19 CAR-T cell infusion or 1 month post last dose of zanubrutinib, whichever is longer, to avoid potential embryonal or fetal exposure. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception Exclusion Criteria: - A history of treatment including any of the following: prior CD19 directed therapy, treatment with alemtuzumab within 6 months before enrollment, prior allogeneic hematopoietic stem cell transplant (SCT) or donor lymphocyte infusion (DLI) within 2 months prior to enrollment - Prior allogeneic stem cell transplant with active graft-versus-host disease (GVHD), or requiring immunosuppressive drugs for treatment of GVHD, or have taken calcineurin inhibitors within 4 weeks prior to consent - Inadequate recovery from adverse events related to prior therapy to grade =< 1 (excluding grade 2 alopecia, neuropathy, and hypertension) - Is unable to swallow oral medication, or has significant gastrointestinal disease that would limit absorption of oral medication - Active bleeding or history of bleeding diathesis (e.g., hemophilia or von Willebrand disease) - Uncontrolled autoimmune hemolytic anemia (AIHA) or idiopathic thrombocytopenic purpura (ITP) - Presence of a gastrointestinal ulcer diagnosed by endoscopy within 3 months before screening - Clinically significant cardiovascular disease such as symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of screening, or any class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification.

Women of childbearing potential must have a negative serum pregnancy test. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with CAR-T cells, breastfeeding should be discontinued. These potential risks may also apply to other agents used in this study - Evidence of myelodysplasia or cytogenetic abnormality indicative of myelodysplasia on any bone marrow biopsy prior to initiation of therapy - Serologic status reflecting active hepatitis B or C infection at screening. Patients that are positive for hepatitis B core antibody, hepatitis B surface antigen (HBsAg), or hepatitis C antibody must have a negative polymerase chain reaction (PCR) at screening.
