Bispecific Antibody-Based Salvage Therapy Followed by CAR-T ± ASCT in R/R Aggressive B-Cell Lymphoma

Recruiting now · Phase 2

Conditions studied: Relapsed or Refractory Aggressive B-cell Lymphoma

In brief

This study consists of two sequential treatment phases. In the first phase, patients with r/r aggressive B-NHL receive two cycles of glofitamab ± investigator-selected agents. In the second phase, patients eligible for CAR-T monotherapy undergo FC lymphodepletion followed by CAR-T infusion (2-4×10⁶/kg), while those eligible for CAR-T+ASCT receive conditioning chemotherapy with PBSC reinfusion on day 0 and CAR-T administration (2-4×10⁶/kg) on day +3 (±1). Patients demonstrating Deauville 4-5 or ctDNA positivity at day 28 post-CAR-T infusion subsequently receive four cycles of glofitamab consolidation therapy.
