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.

• 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.
