FORBES: Biogen Says Its FDA Delay Unrelated To Abbott's Failed Medicine

Macrocyclic drugs are an emerging class of therapeutics that promise to open up drug target spaces which are poorly addressed by small chemical entities and larger biologics.

FORBES: Innovation Snapshot: Macrocyclic drugs to unlock new therapeutic targets

There are eight new chemical entities in various stages of development that have generated four investigational new drug applications with the FDA. Since the payoff from these projects is far in the future, Ranbaxy's labs will continue pumping out generics, which net the company an aftertax margin of 16%.
