About

The purpose of the study is to assess the safety, tolerability and PK of selumetinib (AZD6244; ARRY-142886) (Hyd-Sulfate) in healthy male Japanese and non-Japanese Asian volunteers following administration of a single dose. Standard safety assessments including ECGs, vital signs, blood/urine safety tests, PK samples and monitoring of adverse events and an optional exploratory pharmacogenetics will be performed.

• The period of exclusion begins 3 months after the final dose or 1 month after the last visit whichever is the longest. Note: volunteers consented and screened, but not randomized in this study or a previous Phase I study, are not excluded.Previous administration of study IP in the present study.- involvement in the planning and/or conduct of the study of any RPL/third party contractor or AstraZeneca employee and their close relatives regardless of their role in accordance with their internal procedures.- judged by the Investigator that the volunteer should not participate in the study if they have any ongoing or recent (i.e., during the screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions, and requirements.-
