a clinical study exploring ct1190b in the treatment of patients with relapsed/refractory b-cell non-hodgkin lymphoma

Conditions: B-Cell Non-Hodgkin Lymphoma

Summary: a clinical study to investigate the safety, efficacy, and cellular metabolism of ct1190b car-t cell therapy, in patients with relapsed/refractory b-cell non-hodgkin lymphoma.

this is a single-arm, open-label, dose exploratory clinical study to evaluate the safety, efficacy, cellular pharmacokinetics, and pharmacodynamics of ct1190b cells in patients with b-nhl. it is planned to enroll 6-24 participants.

Eligibility criteria:
