About

To observe the efficacy and safety of a second infusion of relma-cel injection in patients with relapsed or refractory B-cell lymphoma.

Full description

This study aims to collect efficacy and safety data from adult patients with relapsed or refractory large B-cell lymphoma (r/r LBCL) who receive a second infusion of relma-cel injection after initial treatment with relma-cel. The study will not include any form of grouping, and subgroup analysis will be conducted based on the actual data collected.

Inclusion criteria

  • Patients have signed an Informed Consent Form (ICF).
  • Adults diagnosed with relapsed or refractory B-cell lymphoma who have completed initial treatment with Relma-cel.
  • Patients must have undergone at least one disease assessment post-initial Relma-cel treatment, and the investigator decides to administer a second treatment (including PR/PD/SD) based on clinical practice.
  • Before the second infusion, confirm that the prepared dose of relma-cel is sufficient (recommended 80-150 x 10^6 CAR-T cells), with specific dosage determined by the investigator based on patient condition and dose availability.
  • Confirm the presence of CD19+ residual tumor tissue, if clinically permissible.
  • Measure plasma for the absence of anti-drug antibodies (ADA) to relma-cel before the second treatment.
  • Toxicity related to lymphodepleting chemotherapy (fludarabine and cyclophosphamide), except for hair loss, must have resolved to ≤ Grade 1 or returned to baseline levels before retreatment.
  • Patients must not have experienced severe adverse reactions during the first treatment, or any adverse reactions must have resolved to baseline levels from the first treatment.

Exclusion criteria

  • Patients with hypersensitivity to active ingredients or any excipients (e.g., dimethyl sulfoxide, compound electrolyte injection, human albumin).
  • Patients with uncontrolled systemic fungal, bacterial, viral, or other infections
