Evaluate the Safety of UF-KURE19 Cells in Non-Hodgkin Lymphomas

• Status: Not yet recruiting
• Trial end date: 2026-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This treatment uses T cells already present in the participant's body that have been modified outside of the body by a lentivirus and then returned by an infusion to target the cancer. Lentivirus is a family of viruses that can be used by scientists to alter cells. The specific type of cells that will be used is called UF-KURE19 chimeric antigen receptor T cells (CAR-T cells). The CAR-T cells that will be reinfused into the body are modified using a lentivirus that is no longer active. The investigators are evaluating UF-KURE19 because it uses a process that is shorter than other approved CAR-T cells. While the shorter manufacture time can be an advantage, the safety of this approach has not been demonstrated.

Criteria

Inclusion Criteria:

• Male or female patients aged 18 years or older.

• Subjects must have histologically confirmed, CD19 positive, non-Hodgkin lymphoma on the most recent biopsy and disease that is relapsed after 2 or more lines of therapy or refractory to chemotherapy (defined as progressive disease or stable disease lasting ≤6 months, as best response to most recent chemotherapy regimen; or disease progression or recurrence ≤12 months after prior autologous stem cell transplantation (ASCT).)

• ECOG Performance status ≤ 2

• At least one measurable lesion according to Lugano Revised Response Criteria for Malignant Lymphoma.

• Minimum of 2 weeks since prior radiation therapy or systemic therapy to treat malignancy at the time of leukapheresis.

• Total bilirubin ≤ 1.5X institutional upper limit of normal.

• AST (SGOT)/ALT (SGPT) ≤ 2.5 X institutional upper limit of normal.

• Calculated creatinine clearance ≥ 30mL/min estimated by the Cockcroft - Gault formula.

• Cardiac ejection fraction of ≥45%, and no evidence of pericardial effusion, as determined by an echocardiogram.

• Adequate pulmonary function, defined as ≤ Grade 1 dyspnea (unless considered secondary to lymphoma) and oxygen saturation (SaO2) ≥ 92% on room air. If pulmonary function tests (PFTs) are performed based on the clinical judgment of the treating physician, patients with forced expiratory volume in 1 second (FEV1) ≥ 50% of predicted and diffusing capacity for carbon monoxide (DLCO) (corrected for hemoglobin) of ≥ 40% of predicted will be eligible.

• 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 during the treatment period and for at least 90 days after the UF-KURE19 CAR-T cell infusion.

• For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm.

Exclusion Criteria:

• Autologous stem cell transplant within 6 weeks of informed consent

• History of allogeneic hematopoietic stem cell transplantation.

• Active central nervous system or meningeal involvement by lymphoma. Subjects with untreated brain metastases/CNS disease will be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Patients with a history of CNS or meningeal involvement must be in a documented remission by CSF evaluation and contrast-enhanced MRI imaging for at least 90 days prior to registration.

• Second active malignancy, other than non-melanoma skin cancer or carcinoma in situ (e.g. cervix, bladder, breast).

• Less than 28 days elapsed between prior treatment with investigational agent(s) and leukapheresis.

• New York Heart Association class IV congestive heart failure.

• Cardiovascular disorders including unstable angina pectoris, clinically significant cardiac arrhythmias, myocardial infarction or stroke (including transient ischemic attack, or other ischemic event) within 6 months prior to registration.

• Known human immunodeficiency virus infection or acquired immunodeficiency syndrome related illness.

• 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) prior to enrollment. (PCR positive patients will be excluded).

• Patients with history of clinically relevant CNS pathology such as epilepsy, seizure disorders, paresis, aphasia, uncontrolled cerebrovascular disease, severe brain injuries, dementia and Parkinson's disease.

• Subjects with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, pulmonary abnormalities or psychiatric illness/social situations that would limit compliance with study requirements.

• History of active autoimmune disease (i.e. rheumatoid arthritis, systemic lupus erythematosus) with requirement of systemic immunosuppressive medications other than low dose steroids [i.e. maximum of 15mg prednisone equivalent] within the last 6 months.
