NCT06876688

Brief Summary

This study aims to evaluate the efficacy and safety of Relma-cel in the treatment of central nervous system lymphoma (CNSL), as well as its pharmacokinetic characteristics. Enrolled patients with relapsed/refractory (R/R) CNSL will receive Relma-cel infusion, followed by Tislelizumab treatment (200mg, IV, q4w, for 12 months) starting on day 35 after infusion. Bruton's tyrosine kinase (BTK) inhibitors will be used in combination as needed. The follow-up period will last for 4 years, monitoring drug safety, disease status, survival, and the pharmacokinetic characteristics of Relma-cel.

Outcome Measures

Primary Outcomes (1)

  • Complete response rate(CRR) at 3-month

    Complete response rate at 3-month is defined as the incidence of subjects achieving complete response (CR) at 3-month after CAR-T infusion according to the Lugano Classification, as determined by study investigators.

    3 months post CAR-T infusion

Secondary Outcomes (3)

  • Progression-Free Survival (PFS)

    2 years post CAR-T infusion

  • Overall Survival (OS)

    2 years post CAR-T infusion

  • Objective remission rate (ORR) at 3-month

    3 months post CAR-T infusion
