Eligibility Criteria
-----------------
Inclusion criteria: Healthy adult males, 18-55 years of age, inclusive 50Kg >body weight <120Kg Body Mass Index (BMI): 19-30 Must be within 20% of the ideal weight based on height and body frame Exclusion criteria: Any medical history or clinically relevant abnormality identified on the screening medical examination, vital sign measurement, 12-lead ECG recording and/or clinical laboratory examination that is deemed by the principal investigator and/or medical monitor to make the subject ineligible for inclusion because of a safety concern. Subjects with rheumatoid arthritis, connective tissue disorders and other conditions known to be associated with chronic inflammation (e.g. Inflammatory Bowel Disease). Positive HIV antibody, Hepatitis B surface antigen, Hepatitis C antibody, or other chronic hepatic disorders at screening. Subjects with chronic infections such as gingivitis, periodontitis, prostatitis, gastritis, urinary track infections, or any active diseases, including tuberculosis or a history of active tuberculosis. Subjects with any acute infection, symptoms suggestive of sinusitis or significant trauma (burns, fractures). History of alcohol consumption exceeding, on average, 14 drinks/week for men (1 drink = 5 ounces of wine or 12 ounces of beer or 1.5 ounces of 80 proof distilled spirits) within 6 months of screening. Positive urine drug (including cotinine) and/or alcohol at screening. A history of smoking within the 3 months prior to screening. Use of prescription or non-prescription drugs, including (but not limited to) vitamins, herbal and dietary supplements (including St. John's Wort) within 7 days (or 14 days if the drug is a potential drug inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication. An exception is acetaminophen which is allowed at doses of ≤ 2g/day. Participation in a clinical study where the subject has received a drug or 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 study medication. The subject has been exposed to more than four new chemical entities within 12 months prior to the first day of dosing. Consumption of any fruit juices (including grapefruit juice) within 7 days prior to the first dose of study medication. A history of cholecystectomy or biliary tract disease including a history of liver disease with elevated liver function tests of known or unknown etiology. History of increased liver function tests (ALT, AST) above upper limit of normal in the past 6 months and/or liver function tests (bilirubin, ALT, AST) above upper limit of normal at Screening. A known history of Gilbert's Syndrome. History of myopathy or rhabdomyolysis. QTc interval > 450msec. An unwillingness of male subjects to abstain from sexual intercourse with pregnant or lactating women; or an unwillingness of the male subject to use a condom/spermicide in addition to having their female partner use another form of contraception, such as: an intrauterine devise (IUD), diaphragm with spermicide, oral contraceptives, injectable progesterone, subdermal implants or a tubal ligation, if the woman could become pregnant from the first dose of study medication until completion of follow-up procedures. Donation of blood in excess of 500 mL within 56 days prior to dosing. History of sensitivity to heparin or heparin-induced thrombocytopenia. Hypersensitivity to rosuvastatin or any component of the rosuvastatin formulation utilised in this study.
