• The subject has participated in a clinical trial and has received a drug or a new chemical entity within 30 days or 5 half-lives, or twice the duration of the biological effect of any drug (whichever is longer) prior to the first dose of current study drug.
• History of drug or other allergy that, in the opinion of the Investigator, contraindicates their participation.
• Where participation in study would result in donation of blood in excess of 500mL within a 56 day period.
