A Phase 2, Placebo-Controlled Study To Evaluate The Efficacy And Safety Of PF-00489791 In Patients With Type 2 Diabetes And Overt Nephropathy
A Phase 2, Randomized, Double-blind, Placebo-controlled, Parallel Group, Multi-center Study To Evaluate The Efficacy And Safety Of Once-daily Administration Of A Phosphodiesterase 5 Inhibitor (Pf-00489791) In Adults With Type 2 Diabetes And Overt Nephropathy
PF-00489791 is an inhibitor of phosphodiesterase type 5. Our hypothesis is that PF-00489791 will enhance the relaxation of blood vessels within the kidney and so reduce blood pressure, improving renal function.
