About this trial
This study is an open-label, single-arm, prospective clinical trial involving patients with relapsed/refractory B-cell lymphoma, aimed at evaluating the safety and efficacy of CAR-T cell infusion.

Single group
Treatments tested in this trial
CY-219 CAR-T
DrugEligible participants should receive preconditioning 5 to 3 days before CAR-T cell infusion. The recommended preconditioning regimen is fludarabine (30 mg/m²/day, for 3 consecutive days) and cyclophosphamide (300 mg/m²/day, for 3 consecutive days) (Flu/Cy). Thirty minutes before infusion, prophylactic medication for allergic reactions should be administered: 25 mg of promethazine hydrochloride or 12.5 mg of diphenhydramine, either intramuscularly or orally. A '3+3' dose-escalation study design will be used, aiming to recruit 9-18 subjects with relapsed/refractory B-cell lymphoma.
