Key DAC Development Considerations

  • Antibody Selection: The targeting component must provide the appropriate balance of specificity, internalization, pharmacokinetics, and tissue distribution. Antibody format selection can significantly influence overall conjugate performance.
  • Conjugation Strategy: Conjugation chemistry affects homogeneity, scalability, stability, and manufacturability. Early selection of the appropriate approach can reduce downstream development risks.
  • Stability & Manufacturability: Successful bioconjugates require careful optimization to preserve functionality while ensuring robust process performance and long-term stability.
  • Early Risk Mitigation: Generating developability data during discovery and preclinical development helps reduce later-stage failures and supports more efficient advancement toward clinical evaluation.
