Subjects should have been on a stable medication regimen for greater than or equal to two months at the screening visit.

• For enrollment to Cohorts 3, 4, and 5, have been on a stable medication regimen for greater than or equal to two months at the screening visit.

• Have normal clinical laboratory test results and ECG, or results with minor deviations, which are not considered to be clinically significant by the investigator.

• If able to reproduce, agree to use an acceptable method of birth control (e.g., condom and spermicide, oral birth control which has been stable for 30 days) or agree to remain abstinent from Visit 2 until 90 days after the last dose of study drug for males and 30 days after the last dose of study drug for females.

Exclusion Criteria:

• Have a history of lactose intolerance or allergy to dairy products.

• Are pregnant or lactating.

• Have a history or presence of significant cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, or neurological disorders which, in the opinion of the investigator, increases the risk of the study drug or may confound the interpretation of study measures.
