A Study Evaluating Safety and Efficacy of C-CAR039 Treatment in NHL Subjects

A Study Evaluating Safety and Efficacy of C-CAR039 Treatment in Relapsed or Refractory NHL Subjects

The trial is a single arm, single-center, non-randomized phase I clinical trial which is designed to evaluate the safety and efficacy of C-CAR039 in treatment of relapsed or refractory NHL patients

Study Overview

• Status: Completed
• Conditions: Non-Hodgkin's B-cell Lymphoma
• Intervention / Treatment: Biological: Prizloncabtagene Autoleucel

Detailed Description

This study plans to enroll 25 patients to assess the safety and efficacy of C-CAR039. Subjects who meet the eligibility criteria will receive a single dose of C-CAR039 injection.

The study will include the following sequential phases: Screening, Apheresis and C-CAR039 manufacturing, Bridging (if needed), Baseline, lymphodepletion, C-CAR039 infusion, and Follow-up Visit.

• Study Type: Interventional
• Enrollment (Actual): 25

• 7. LVEF≥ 50% (ECHO)
• 8. No active pulmonary infections, normal or mild impaired pulmonary function and SpO2≥92%
• 9. Laboratory criteria: ANC≥1.0×109/L; Platelets≥50×109/L; Serum total bilirubin ≤1.5x ULN; Creatinine≤ ULN; AST and ALT≤3x ULN
• 10. No contraindications of apheresis;
• 11. Expected survival ≥ 3months
• 12. ECOG score 0 or 1

Exclusion Criteria:

• 1. Have a history of allergy to cellular products;
• 2. According to the NYHA cardiac function grading standards, patients with grade III or IV cardiac dysfunction;
• 3. A history of craniocerebral trauma, disturbance of consciousness, epilepsy, cerebrovascular ischemia, cerebrovascular hemorrhagic disease, etc.;
• 4. Patients with central nervous system involvement;
• 5. Patients with autoimmune diseases, immunodeficiency or other conditions requiring immunosuppressive therapy;
• 6. Received allogeneic hematopoietic stem cell transplantation before;
• 7. Previous use of any CAR T cell product or other genetically modified T cell therapy;
• 8. Autologous stem cell transplantation within 6 weeks before infusion;
• 9. Severe active infections (except for simple urinary tract infections, bacterial pharyngitis), or currently undergoing intravenous infusion of antibiotics. However, prophylactic antibiotic, antiviral and antifungal infection treatments are permissible;
• 10. Live vaccination within 4 weeks prior to apheresis;
• 11. People infected with HIV, HBV, HCV and TPPA/RPR, and carriers with HBV;
• 12. A history of alcohol abuse, drug use or mental illness;

• 13. Subjects who are not sterilized and have any of the following conditions:

  1. are pregnant/lactating; or
  2. planned pregnancy during the trial; or
  3. being fertile and unable to use effective contraception;
• 14. Severe hypersensitivity to fludarabine or cyclophosphamide;

• 15. A history of other primary cancers other than the following:

  1. Non-melanoma tumors such as basal cell carcinoma of the skin that are cured by excision
  2. Cured in situ cancers such as cervical, bladder, or breast cancer
• 16. The investigators consider that the subject has other conditions that are not suitable for this trial.
