Big Molecule Watch will be posting updates and analyses on regulatory issues, litigation, legislation, and other news in the ever-developing world of biosimilars. The editors of this blog have collectively been watching and engaging with the world of biosimilars (“big molecules”) since before the inception of the biosimilar industry in the U.S., and we’re excited to share the observations of our active watch on this new forum.
