APC isn't the only one asking FDA to rethink its DTE classification. A new citizen petition filed August 27 adds significant legal and scientific weight to the effort, arguing that thyroglobulin, the protein FDA relies on to classify DTE as a biologic, isn't actually the active pharmaceutical ingredient. That distinction belongs to T3 and T4, and the petition argues FDA's own guidance and relevant case law back that up. It complements APC's petition filed in January and strengthens the overall case for keeping patient access intact.
