BIIB021 (originally called CNF2024) is an oral inhibitor of heat shock protein 90 (HSP90) originally under development by Conforma Therapeutics.  Following acquisition of Conforma, development is proceeding under the new owner, Biogen Idec, under the new name BIIB021.  For information at the website of the manufacturer, link here.
