Fosdagrocorat (developmental code names PF-04171327 and PF-4171327; also known as dagrocorat 2-(dihydrogen phosphate)) is a nonsteroidal but steroid-like selective glucocorticoid receptor modulator (SGRM) which was under development for the treatment of rheumatoid arthritis but was never marketed.[1][2][3][4] It is the C2 dihydrogen phosphate ester of dagrocorat, and acts as a prodrug of dagrocorat with improved pharmacokinetics.[5][6] The drug reached phase II clinical trials prior to the discontinuation of its development.[1][3][4]
