BDC-4182

BDC-4182 is a next-generation BoltbodyTM ISAC targeting claudin 18.2, a clinically validated target with expression in gastric cancer, gastroesophageal junction cancer, pancreatic cancer, and other tumor types. In preclinical models, BDC-4182 demonstrated significant anti-tumor activity in low claudin 18.2-expressing cancer models, induced immunological memory, and outperformed cytotoxic claudin 18.2 ADCs. Our next-gen Boltbody ISAC BDC-4182 is under development for gastric and gastroesophageal cancers. Enrollment is open for the Phase 1 dose-escalation trial. Learn more at Clinicaltrials.gov.

 

BDC-4182

BDC-4182 Opportunity

  • Clinically validated target in gastric cancer
  • Large addressable market
  • First-in-human clinical trial ongoing

Key Attributes

  • Activity in low-antigen-density tumors brings hope to new patients
  • Immunological memory protects against tumor re-challenge and recurrence
  • Dramatically more potent than BDC-1001 in preclinical assays

Differentiation in Claudin 18.2 Landscape

  • Superior efficacy versus TOPO1 and MMAE-ADCs in multiple experiments
  • Potential for longer durable responses and recurrence prevention
  • Safety benefit seen preclinically versus cytotoxic ADCs
