What defines a drug as a FoB or biosimilar is not the process to arrive at the finished product but rather the process to obtain regulatory approval. As stated in my prior post, if a drug obtains regulatory approval without relying, in whole or in part, on the clinical data of another drug, then it is not a FoB or biosimilar––it is simply a branded drug.
