Population Pharmacokinetics of Fosdagrocorat (PF-04171327), a Dissociated Glucocorticoid Receptor Agonist, in Patients With Rheumatoid Arthritis.

ABSTRACT: Dissociated agonists of the glucocorticoid receptor (DAGRs) show similar antiinflammatory effects but improved tolerability compared with standard glucocorticoid receptor (GR) agonists. The prodrug fosdagrocorat (PF-04171327), with active DAGR metabolite PF-00251802 (Metabolite-1), is postulated to show superior efficacy over placebo and prednisone in patients with moderate to severe rheumatoid arthritis (RA). We investigated the population pharmacokinetics of active Metabolite-1 and its active metabolite PF-04015475 (Metabolite-2) in patients with moderate to severe RA enrolled in a 12-week, phase II, randomized, double-blind study (NCT01393639). A simultaneous fit of a two-compartment model for Metabolite-1 and a one-compartment model for Metabolite-2 provided an adequate fit to the data
