Clinical Trial Summary

To evaluate the efficacy and safety of post-marketing Regiorense injection secondary infusion in the treatment of adult patients with relapsed or refractory B-cell lymphoma.


Description:

CD19-targeted chimeric antigen receptor T-cell therapy has shown remarkable efficacy in relapsed or refractory B-cell malignancies. However, CD19 CAR-T cells are still unable to induce durable remissions in some patients. Further therapeutic strategies remain to be explored for patients who fail to achieve complete remission (CR) or who relapse after CAR-T treatment. the mechanisms underlying the failure of CAR-T cell therapy may be diverse and not yet fully understood. It may be due to the patient's own poor T-cell function, immunosuppressive tumour microenvironment, loss of tumour-targeting antigen expression with antitumour therapy, and compromised CAR-T renewal in vivo, or T-cell depletion due to the tumour microenvironment. It has recently been demonstrated that CAR-T cells become functionally depleted, or CAR lost, with sustained exposure to tumour antigen stimulation (Good, C, 2021). Extensive clinical experience suggests that CAR-T cell expansion and persistence are required to achieve a durable response. In patients requiring follow-up therapy after failure of the first CAR-T cell infusion (CART1), one option is a second infusion of CD19 CAR-T cells (CART2) for retreatment, and a second infusion of CD19 CAR-T cells (CART2) is considered a possible approach to improve prognosis.

Intervention

Drug:
Relmacabtagene Autoleucel Injection
For patients who had undergone at least one disease assessment after the first treatment of Relmacabtagene Autoleucel injection and whose disease status was not complete remission, the investigators decided to give the patients a second treatment of Relmacabtagene Autoleucel injection based on clinical practice, and the specific dosage was determined by the investigators according to the patient's condition and dose reserve.
