Technology Platforms

Biocytogen RenLite Platform:

  • Fully human common light chain antibody discovery platform
  • Generates bispecific antibodies with reduced immunogenicity
  • Enables streamlined manufacturing and improved developability

Acepodia AD2C Technology:

  • Antibody‑Dual Drug Conjugate platform for dual‑payload ADCs
  • Enhances tumor‑specific cytotoxicity and overcomes resistance mechanisms
  • Synergistic combination with RenLite enables novel BsADC architectures

Strategic Rationale

For Biocytogen:

  • Technology Monetization: Leverages RenLite platform for global BsADC partnerships beyond internal pipeline
  • Non‑Dilutive Funding: Option fees and milestones provide capital for R&D expansion
  • Platform Validation: Acepodia partnership validates BsADC strategy, attracting additional global licensees

For Acepodia:

  • Pipeline Acceleration: Gains access to novel BsADC candidates for solid tumor and hematologic malignancy programs
  • Manufacturing Advantage: RenLite platform reduces CMC complexity associated with bispecific antibodies
  • Global Reach: Exclusive licenses enable worldwide development and commercialization

Market Opportunity: Bispecific ADCs

Global ADC Market: $6.5 billion (2025), projected $15 billion by 2030, growing at 18% CAGR

Bispecific ADC Sub‑Segment: Emerging class with $2‑3 billion potential by 2030, targeting resistant tumor populations

Key Advantages:

  • Dual Targeting: Overcomes antigen heterogeneity and resistance
  • Enhanced Payload Delivery: Dual warheads increase tumor cell kill rate
  • Differentiation: First BsADC platform with global licensing traction
