Details and patient eligibility

About

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

Full 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.

1. At least two weeks from last treatment (radiation, chemotherapy, mAb, etc) to apheresis;
1. LVEF≥ 50% (ECHO)
1. No active pulmonary infections, normal or mild impaired pulmonary function and SpO2≥92%
1. Laboratory criteria: ANC≥1.0×109/L; Platelets≥50×109/L; Serum total bilirubin ≤1.5x ULN; Creatinine≤ ULN; AST and ALT≤3x ULN
1. No contraindications of apheresis;
1. Expected survival ≥ 3months
1. ECOG score 0 or 1

1. A history of other primary cancers other than the following:
2. Non-melanoma tumors such as basal cell carcinoma of the skin that are cured by excision
