Biological Activity
GS-9901 is a potent, orally active and highly selective inhibitor of PI3Kδ (PI3Kdelta IC50 = 1.0nM, HWB delta EC50 = 1.5 nM; CLpr hHep = 0.05 L/h/kg.). GS-9901 displays an excellent pharmacokinetic profile and is efficacious in a rodent model of rheumatoid arthritis. GS-9901 demonstrates efficacy in a rat model of arthritis and is predicted to be suitable for q.d. dosing in humans. The favorable in vitro and in vivo attributes of GS-9901 resulted in its selection as a development candidate.
