Criteria

Inclusion Criteria:

• Informed Consent Form (ICF) was obtained from the patients.

• Diagnosed relapsed or refractory B-cell lymphomas

3. grade 3b follicular lymphoma

4. primary mediastinal large B-cell lymphoma

5. high-grade B-cell lymphoma with MYC and BCL-2 and/or BCL-6 rearrangements (double/triple hit lymphoma)

6. adult follicular lymphoma refractory to second-line or later systemic therapy or relapsed within 24 months Adult patients who had completed the first treatment with remifentanil injection;

• The patient had undergone at least one post-treatment disease assessment with Relmacabtagene Autoleucel Injection, and the investigator decided to retreat the patient (including PR\PD\SD) with commercially available Relmacabtagene Autoleucel injection based on clinical practice;

• Confirmation of residual tumor tissue CD19+ in patients, if clinically permissible；

• Absence of antidrug antibody (ADA) to ricciolenz in plasma before retreatment；

• Toxicity associated with lymphocyte-clearing chemotherapy (fludarabine and cyclophosphamide), with the exception of alopecia, that resolved to ≤ grade 1 or returned to pre-first treatment levels before retreatment.

• The patients did not have serious adverse reactions during the first treatment, or the adverse reactions during the first treatment had resolved to the baseline level of the first treatment.
