Non Hodgkin Lymphoma Clinical Trial
Zanubrutinib and Lisocabtagene Maraleucel for the Treatment of 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.
I. To evaluate the efficacy of the combination of zanubrutinib and lisocabtagene maraleucel (liso-cel) for the treatment of Richter's syndrome (RS).
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
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.
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.

If cytopenias are due to disease in the bone marrow any degree of anemia or thrombocytopenia are allowed, absolute neutrophil count (ANC) must be >= 500
Absolute neutrophil count (ANC) >= 1000/mm^3 (independent of growth factor support or infusion support at screening unless evidence shows that the cytopenia[s] is due to marrow involvement by CLL/SLL). If cytopenias are due to disease in the bone marrow any degree of anemia or thrombocytopenia are allowed, ANC must be >= 500

Combined (estrogen- and progestogen- containing) hormonal contraception associated with the inhibition of ovulation
Oral, intravaginal, or transdermal
Progestogen-only hormonal contraception associated with the inhibition of ovulation
Oral, injectable, implantable
Of note, barrier contraception (including male and female condoms with or without spermicide) is not considered a highly effective method of contraception, and, if used, this method must be used in combination with another acceptable method listed above. If patient is using hormonal contraceptives such as birth control pills or devices, a barrier method of contraception (eg, condoms) must also be used
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 90 days after the CAR-T cell infusion.
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 6 months after the anti-CD19 CAR-T cell infusion. 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 6 months after the human anti- CD19 CAR-T cell infusion 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
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. Note: Subjects with controlled atrial fibrillation can enroll on study

Human immunodeficiency virus (HIV) seropositivity
Subjects with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, unstable angina pectoris, pulmonary abnormalities or psychiatric illness/social situations that would limit compliance with study requirements
Pregnant or breastfeeding women are excluded from this study because CAR-T cell therapy may be associated with the potential for teratogenic or abortifacient effects. 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. 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. PCR positive patients will be excluded
