A peptide program does not inherit the small-molecule impurity framework, and it does not inherit the biologic one. Ina Q3A(R2) excludes peptides, ICH Q6B excludes synthetic peptides, and the EMA guideline effective 1 Yuni 2026 supplies the peptide-specific framework in their place, with Ph. Yuro. 2034 thresholds and product-specific limits. That is the structural fact behind the partnering question, and it is independent of any vendor’s timeline.
The integrated DNA-to-IND model is a coherent answer to a recombinant problem. Its named molecule classes are mAbs, bispecifics da Fc-fusion sunadaran, its entry points begin at vector construction, and its clock starts at DNA transfection. A chemically synthesized peptide has none of those inputs, so the fit question is answered before cost or speed enters the discussion.
