ClinConnect Summary
This clinical trial is testing a new treatment called JWCAR239 for people with certain types of B-cell non-Hodgkin lymphoma, which is a kind of blood cancer affecting the immune system. JWCAR239 is a special therapy that uses the patient’s own immune cells, modified in a lab to better recognize and attack cancer cells. This study aims to find out if the treatment is safe, how the body processes it, and whether it helps control the lymphoma.
People who might join this trial are adults with specific types of B-cell lymphoma, such as diffuse large B-cell lymphoma or mantle cell lymphoma, who have not responded well to at least two previous treatments or stem cell transplant. Participants need to have measurable tumors and be in generally good health aside from their cancer. Women of childbearing age and men with partners who can have children must use effective birth control during the study and for some time afterward. The trial is not yet open for enrollment, and participants can expect close monitoring to assess how they respond to the treatment and to watch for any side effects. It’s important to know that this study excludes people with certain infections, recent heart problems, brain conditions, or prior treatments with similar cell therapies.

- • 6. Adequate vascular access for leukapheresis.
- • 7. Expected survival \>12 weeks.
- • 8. Non-abstinent female subjects of childbearing potential must agree to use a highly effective contraceptive method plus an additional barrier method from at least 28 days before lymphodepletion until 2 years after JWCAR239 infusion. Male subjects with fertile partners must agree to use effective contraception from at least 28 days before lymphodepletion until 2 years after JWCAR239 infusion and must not donate semen or sperm throughout the study.
- Exclusion Criteria:
- • 1. Lymphoma involving the central nervous system (CNS).
- • 2. EBV-positive DLBCL or Richter transformation of chronic lymphocytic leukemia.
- • 3. History of other malignant tumors with complete remission for less than 2 years, or current presence of other malignant tumors (exceptions to the 2-year restriction include: basal cell carcinoma of the skin, squamous cell carcinoma of the skin, treated localized prostate cancer, biopsy-confirmed cervical in situ carcinoma, or cervical smears showing squamous intraepithelial lesions, or completely resected tumors with low recurrence potential as assessed by the investigator).
- 4. At screening, the subject has:
- • Active hepatitis B or C (subjects with HBV DNA or HCV RNA below the lower limit of the central reference value by PCR may be enrolled). For occult or prior HBV-infected subjects, prophylactic antiviral therapy and regular monitoring of HBV-DNA are required.
- • Human immunodeficiency virus (HIV) infection or syphilis infection.
- • 5. Acute deep vein thrombosis (DVT) (tumor thrombus or thrombus) or pulmonary embolism (PE) within 3 months prior to informed consent signing.
- • 6. Receiving anticoagulant therapy for acute DVT or PE within 3 months prior to informed consent signing (prophylactic treatment ).
- • 7. Uncontrolled systemic fungal, bacterial, viral, or other infections.
- • 8. Acute or chronic graft-versus-host disease (GvHD).
- • 9. History of any of the following cardiovascular diseases within the past 6 months: New York Heart Association (NYHA) Class III or IV heart failure, coronary angioplasty or stenting, myocardial infarction, unstable angina, or other clinically significant heart diseases.
- • 10. Clinically significant CNS disease or symptoms at screening or within the past 6 months, such as epilepsy, seizures, paralysis, aphasia, stroke, severe brain injury, dementia, Parkinson's disease, cerebellar disease, organic brain syndrome, or psychiatric disorders.
- • 11. Pregnant or lactating women. Females of childbearing potential must have a negative serum pregnancy test within 48 hours before starting lymphodepletion chemotherapy.
- 12. Use of any of the following drugs or treatments within the specified time before leukapheresis:
- • Alemtuzumab within 6 months before leukapheresis. Bendamustine within 6 months before leukapheresis. Cladribine within 3 months before leukapheresis. Fludarabine within 3 months before leukapheresis. Anti-CD20 monoclonal antibodies within 7 days before leukapheresis. Venetoclax within 4 days before leukapheresis. Idelalisib within 2 days before leukapheresis. Lenalidomide within 1 day before leukapheresis. Pharmacological doses of corticosteroids (defined as prednisone \>5 mg/day or equivalent) within 7 days before leukapheresis or within 72 hours before JWCAR239 injection. Physiological replacement, topical, and inhaled steroids are permitted.
- • Chemotherapy (e.g., vincristine, rituximab, cyclophosphamide) required to control the disease after leukapheresis must have been discontinued ≥7 days before lymphodepletion chemotherapy.
