Descriptive Information
Brief Title  ICMJE A Study of the Safety, Tolerability, Pharmacokinetics, And Effects On Histamine-Induced Wheal Of PF-05180999 In Healthy Adults
Official Title  ICMJE A Phase 1, Placebo-Controlled, Crossover, Subject- And Investigator-Blind, Sponsor-Open Study To Evaluate The Safety, Tolerability, Pharmacokinetics, And Effects On Histamine-Induced Wheal Of A Modified-Release Formulation Of PF-05180999 In Healthy Adult Subjects
Brief Summary PF-05180999 is a phosphodiesterase-2 inhibitor that is hypothesized to be able to reduce vascular permeability. The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and effects on histamine-induced wheal of single doses of PF-05180999 in healthy adult subjects. Histamine-induced wheals are biomarkers of vascular permeability.
