In my view, the article seriously misstates international norms regarding approval of biosimilars and creates a misimpression that the new Colombian regime is consistent with the approach taken in Europe and the United States. In fact, the Colombian regulation departs significantly from international norms. Generally speaking, the consensus approach in the rest of the world involves two pathways to market for biological medicines: a full dossier with robust preclinical and clinical evidence of safety and effectiveness, and an abbreviated dossier with a robust showing of similarity to an originator product sufficient to justify reliance on the originator’s safety and effectiveness research. There is no third pathway.
