CAR-T therapy after stem cell transplant for relapsed B-cell lymphoma

A Single-Arm Clinical Study of CD19 CAR-T Following ASCT for Relapsed/Refractory B-Cell Non-Hodgkin's Lymphoma (R/R B-NHL) With High-Risk Prognostic Factors

Phase 2 Interventional Ruijin Hospital · NCT06365671

This study is testing if a new CAR-T therapy can help people with relapsed B-cell lymphoma feel better after they’ve had a stem cell transplant.

What this trial studies

This clinical trial evaluates the safety and efficacy of Relmacabtagene autoleucel (relma-cel) infusion following high-dose chemotherapy and autologous stem-cell transplantation in patients with relapsed or refractory B-cell Non-Hodgkin's Lymphoma who have high-risk prognostic factors. It is a single-center, open-label, prospective study that aims to assess the best complete response rate within three months, along with other response rates and the incidence of treatment-related toxicities. Participants will receive a fixed dose of relma-cel on day +3 after transplantation, and various safety and efficacy endpoints will be monitored throughout the trial.

Who should consider this trial

Good fit: Ideal candidates include individuals with histologically confirmed B-cell non-Hodgkin's lymphoma who have relapsed or refractory disease after prior treatments.

Not a fit: Patients with non-B-cell lymphomas or those who have not received prior anti-CD20 monoclonal antibody and anthracycline-containing chemotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for patients with high-risk relapsed B-cell lymphoma.

How similar studies have performed: Other studies have shown promising results with CAR-T therapies in similar patient populations, indicating a potential for success with this approach.

Eligibility criteria

Inclusion Criteria:

1. Histologically confirmed B-cell non-Hodgkin's lymphoma including the following types

   * diffuse large B-cell lymphoma
   * high-grade B-cell lymphoma with or without MYC and BLC2 and/or BCL6 rearrangement
   * transformed lymphoma
   * primary mediastinal large B-cell lymphoma
   * follicular lymphoma (FL)
2. Relapsed or refractory diseases fulfilling one of the following criteria (individuals must have received anti-CD20 monoclonal antibody and anthracycline-containing chemotherapy regimen)

   * Primary refractory disease, defined as disease progression after first-line immunochemotherapy or disease progression within 6 weeks of the end of the last chemotherapy
   * Stable disease (SD) as best response after at least 4 cycles of first-line therapy
   * Partial response (PR) as best response after at least 6 cycles of first-line therapy (biopsy-proven residual disease is needed for individuals with Deauville score of 4)
   * PR as best response after at least 2 cycles of second-line therapy
   * Disease relapse ≤12 months after the completion of first-line immunochemotherapy
   * Relapsed or refractory disease after ≥2 lines of chemotherapy

4. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
5. Eligible for HDCT/ASCT based on the investigator's assessment and are scheduled to undergo an ASCT sequential CAR-T treatment regimen
6. Adequate renal and hepatic function defined as:

   * Serum alanine aminotransferase (ALT/AST) ≤ 3 upper limit of normal (ULN)
   * Total bilirubin ≤1.5 mg/dL(\<3 times ULN in patients with Gilbert's syndrome, cholestasis due to hepatoportal compression adenopathy, biliary obstruction in patients with liver involvement or lymphoma)
   * Serum creatinine ≤1.5 ULN, or creatinine clearance (as estimated by Cockcroft Gault) ≥ 30 mL/min
7. Cardiac ejection fraction ≥ 40%
8. Baseline oxygen saturation \> 95% on room air
9. Life expectancy ≥3 months

Exclusion Criteria:

1. History of autologous or allogeneic stem cell transplantation
2. Active HBV or HCV infection, defined as HBV-DNA or HCV-DNA levels above the normal upper limit, with or without abnormal liver function. Individuals with positive HBsAg or HBcAb should receive antiviral prophylaxis for at least 12 months after CAR-T cells infusion.
3. Presence of uncontrolled infection, cardio-cerebrovascular disease,coagulopathy, or connective tissue disease.
4. History of HIV infection
5. Prior chimeric antigen receptor cellular immunotherapy targeting CD19
6. Pregnant or lactating patients
