A Study of C-CAR039 Treatment in Subjects With r/r NHL SubjectsNon-Hodgkin's Lymphoma

Phase 1

Active, not recruiting

• Conditions: Non-Hodgkin's B-cell Lymphoma
• Interventions: Biological: Prizloncabtagene autoleucel

• Registration Number: NCT04696432
• Lead Sponsor: Tianjin Medical University Cancer Institute and Hospital

Brief Summary

This is a single-center, open-label study to evaluate the safety and efficacy of C-CAR039 in relapsed and/or refractory B-NHL patients.

Detailed Description

This is a single-arm, open label, phase I study to evaluate the safety and preliminary efficacy of C-CAR039 in adults with relapsed/refractory B-cell Non-Hodgkin's Lymphoma. 10 patients are planned to be enrolled. Following consent, enrolled subjects will undergo a leukapheresis procedure to collect autologous mononuclear cells for manufacture of C-CAR039. Following manufacture of the drug product, subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide prior to C-CAR039 infusion. All subjects who have received C-CAR039 infusion will be followed for up to 24 months

6. Female subjects who have been pregnant or breastfeeding, or who plan to conceive during or within 1 year after treatment, or male subjects' partner plans to conceive within 1 year after C-CAR039 infusion;
7. Active or uncontrolled infections requiring systemic treatment within 14 days before enrollment;
8. Patients who have been previously infected with tuberculosis;
9. Administered Corticosteroids and/or other immunosuppressants within 7 days before apheresis. and 5 days before the infusion of C-CAR039;
