Legend Biotech Establishes Clinical Proof-of-Concept for LB2501, a Potential First-in-Class In Vivo CD19/CD20 Dual-Targeting CAR-T, in Relapsed/Refractory B-Cell Non-Hodgkin Lymphoma

•  Achieved 100% ORR and 83.3% CR rate at dose level 2 following a single infusion in patients with relapsed/refractory B-NHL in an ongoing Phase 1 study
  
• Single infusion of LB2501 generated dose-dependent in vivo CAR-T expansion without lymphodepletion
  
• No dose-limiting toxicities, serious adverse events, ICANS, or deaths were reported; infusion-related reactions and CRS were Grade 1–2, and none required glucocorticoids for CRS management
  
• Additional translational data showed rapid vector clearance, polyclonal vector integration, and no evidence of non-specific transduction
  
• Proof-of-concept progress demonstrates leadership in next-generation cell therapies, with results presented in a late-breaking session at EHA 2026
  

BRIDGEWATER, N.J., June 14, 2026 (GLOBE NEWSWIRE) -- Legend Biotech Corporation (NASDAQ: LEGN) (Legend Biotech), a global leader in cell therapy, today announced first clinical proof-of-concept data for LB2501, its investigational in vivo CD19/CD20 dual-targeting CAR-T cell therapy, in patients with relapsed or refractory B-cell non-Hodgkin lymphoma (R/R B-NHL). The results are being presented today in a late-breaking session at the European Hematology Association (EHA) 2026 Congress (Abstract #LB5006).

In the ongoing Phase 1 study, a single infusion of LB2501 generated dose-dependent in vivo CAR-T expansion without lymphodepletion. At the higher dose level (DL2), LB2501 achieved a 100% objective response rate (ORR) (6/6) and an 83.3% complete response rate (CR) (5/6), with all responses ongoing at the time of data cutoff. LB2501 also showed a favorable safety profile, with no dose-limiting toxicities (DLTs), serious adverse events (SAEs), immune effector cell-associated neurotoxicity syndrome (ICANS), or deaths reported.

“In vivo CAR-T represents a compelling frontier in cell therapy, enabling the generation of CAR-T cells directly within the patient, with the potential to simplify treatment and expand access over time,” said Ying Huang, Ph.D., Chief Executive Officer of Legend Biotech. “LB2501 is our step toward realizing that vision and reflects further progress toward our goal of leading the future of cell therapy. Backed by the commercial and scientific foundation we have built with CARVYKTI, we are well-positioned to advance this next generation of CAR-T delivery. These early data, with deep responses from a single infusion across patients, give us confidence in the path ahead.”
