Details and patient eligibility


n this study, approximately 30 patients with relapsed or refractory non-Hodgkin's lymphoma (NHL) were recruited for a single reinfusion of IM19-CD28 and IM19-41BB CAR-T cells. Assess the safety, tolerability of treatment, and initially observe the efficacy.

Full description

Dose-escalation:Patients entered the IM19-41BB or IM19-CD28 group and performed dose escalation studies in three dose groups. According to the results of the previous dose escalation study, select one dose to continue the enrollment of 6 patients for extended studies.


30 estimated patients




18+ years old


No Healthy Volunteers
