Clinical Trial Summary

This is a single-arm, open label, dose escalation, phase I study of C-CAR039 in adults with relapsed/refractory B-cell Non-Hodgkin's Lymphoma.

Description:

This is a single-arm, open label, "3+3" dose escalation, 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.

4. Any uncontrolled, active disease that prevents participation in the trial;

5. 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 their cell transfusion;

6. Active or uncontrolled infections requiring systemic treatment within 14 days before enrollment;

7. Patients who have been previously infected with tuberculosis;

8. Administered Corticosteroids and/or other immunosuppressants within 7 days before apheresis. and 5 days before the infusion of C-CAR039;

9. Patients with central nervous system involvement;

10. Any systemic antitumor therapy was performed within 2 weeks before conditional treatment chemotherapy pretreatment;

11. Any situation that the investigator believes would compromise the safety of the subject or interfere with the purpose of the study;

12. Those with medical conditions that prevent them from signing the written informed consent or from complying with the study procedures; or those who are unwilling or unable to comply with the study requirements.

13. Other conditions deemed unsuitable for enrollment by the investigator.
