• existing cardiac or hematological diseases and/or pathological findings which might interfere with safety, pharmacodynamic effect and/or pharmacokinetics of ezetimibe and sirolimus

• existing hepatic and renal diseases and/or pathological findings which might interfere with safety, pharmacodynamic effect and/or pharmacokinetics of ezetimibe and sirolimus

• existing gastrointestinal diseases and/or pathological findings which might interfere with safety, pharmacodynamic effect and/or pharmacokinetics of ezetimibe and sirolimus

• acute or chronic diseases which could affect drug absorption or metabolism

• history of any serious psychological disorder

• drug or alcohol dependence

• positive drug or alcohol screening

• smokers of 10 or more cigarettes per day

• positive screening results for HIV, HBV and HCV
