Practical Solutions and Value in CD19-Directed Therapy for DLBCL
Overview
- Several treatment options are available for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL).
- These options include monoclonal antibody therapy, antibody-drug conjugate therapy, and chimeric antigen receptor T-cell therapy (CAR-T).
Challenges
- Assessing CD19 expression levels and determining the best treatment sequencing strategies are current challenges in CD19-directed therapy.
- Antigen escape, such as epitope loss and defective cell-surface trafficking of CD19, is a significant cause of CAR-T failure.
Value and Future Directions
- Retrospective analyses suggest that some patients may benefit from subsequent CD19-directed therapy after relapse following CAR-T treatment.
- Prospective studies are needed to understand how pre- and post-treatment CD19 expression correlates with clinical responses to subsequent CD19-directed therapy.
- These studies will help optimize treatment strategies and maximize the benefits of CD19-directed therapy for patients with DLBCL.
