Epcoritamab Plus Lenalidomide in Relapsed/Refractory Large B-cell Lymphoma After Second-Line CAR T-cell Therapy (BiFAST)

8 de septiembre de 2026 actualizado por: The Lymphoma Academic Research Organisation

A Phase II Trial Evaluating Fixed Dose and Faster Ramp-up of Epcoritamab With Lenalidomide for 3L Relapse/Refractory Large B-cell Lymphoma After CAR T-cells Therapy in 2nd Line

The goal of this Phase 2, open-label, multicenter clinical trial is to assess the efficacy and safety of accelerated ramp-up and fixed-dose subcutaneous epcoritamab combined with lenalidomide in adults with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) following progression after second-line CAR T-cell therapy.

The main question it aims to answer is :

- What is the overall response rate (ORR) after Cycle 2, or at premature treatment discontinuation (PTD), according to the 2014 Lugano Response Criteria?

Participants will:

  • Receive subcutaneous epcoritamab administered according to an accelerated ramp-up schedule followed by fixed dosing, in combination with lenalidomide.
  • Undergo clinical evaluations, laboratory assessments, and PET-CT imaging to determine disease status based on the 2014 Lugano Response Criteria.
  • Continue study therapy for up to 48 weeks.
  • Enter a follow-up period of at least 24 months after the last dose to monitor long-term outcomes and safety.

Approximately 55 adults will be enrolled across multiple centers in France. Eligible individuals must have R/R LBCL, including diffuse large B-cell lymphoma and other eligible LBCL subtypes, with progressive metabolic disease documented by PET-CT at least 1 month after second-line CAR T-cell therapy. The overall study duration is expected to be approximately 5 years.
