Legend Biotech Announces U.S. FDA Clearance of IND Application for Solid Tumor CAR-T, LB1908 for Relapsed or Refractory Gastric, Esophageal and Pancreatic Cancers

SOMERSET, NJ, USA I June 03, 2022 I Legend Biotech Corporation (NASDAQ: LEGN) (Legend Biotech), a global biotechnology company developing, manufacturing and commercializing novel therapies to treat life-threatening diseases, today announced that the U.S. Food and Drug Administration (FDA) has cleared its investigational new drug (IND) application to evaluate LB1908 in a Phase 1 clinical trial in the United States. LB1908 is an investigational, autologous chimeric antigen receptor T-cell (CAR-T) therapy selectively targeting Claudin 18.2 through a high-affinity VHH antibody for the treatment of adults with relapsed or refractory gastric, esophageal (including gastro-esophageal junction) or pancreatic cancers. Claudin18.2 is a tight junction protein commonly expressed in patients with these cancer subtypes.1

The Phase 1, first-in-human, open-label, multicenter clinical study seeks to characterize the safety and tolerability of LB1908, as well as determine the recommended dose for Phase 2 and evaluate preliminary efficacy. Study will have dose escalation and dose expansion phases. Patients enrolled in the study must sufficiently express Claudin 18.2.

A Phase 1 investigator-initiated trial evaluating LB1908 for advanced gastric cancers is also ongoing in China (NCT04467853).

“Treatment options for patients with esophageal, stomach and pancreatic cancers have improved in the last ten years, but patients in the advanced stages still face poor prognoses worldwide. Thousands of people have no symptoms until their cancers have moved into late phases and at that point, surgery is no longer an option,” said Lida Pacaud, M.D., Vice-President of Clinical Development. “Based on prevailing research, we are optimistic that a CAR-T therapy targeting Claudin 18.2 can be integrated in future treatment strategies for those with relapsed or refractory gastrointestinal cancers. We look forward to the start of the trial.”

About Gastric, Esophageal and Pancreatic Cancers
Stomach, esophageal and pancreatic cancers affect the tissue or glands lining these organs. They are often diagnosed when the diseases have progressed to advanced stages. In the U.S., there are an estimated 123,920 people living with stomach cancer and 49,084 living with esophageal cancers.2,3 An estimated 89,248 people in the U.S. live with pancreatic cancer. While all three cancers are treatable, the five-year survival rate is just 32% for gastric cancer; 20% for esophageal cancer; and 11.5% for pancreatic cancer, with definitive treatment at all stages of progression.4,5,6
