Male participants: 1) Female partners must not be pregnant or lactating. 2) Must agree to remain abstinent (refrain from heterosexual intercourse) or must agree to use a condom with spermicide during the treatment period and for at least 28 days after the last dose of study drug with female partners of childbearing potential. 3) Must agree to refrain from donating sperm during the treatment period and for at least 28 days after the last dose of study drug Exclusion Criteria Have a history or symptoms of any clinically significant cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, oncologic or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; of constituting a risk when taking the study treatment; or of interfering with the interpretation of data Confirmed (based on the average of 3 separate resting BP measurements in a supine position, after at least 5 minutes rest) systolic BP greater than 140 or less than 90 mmHg, and diastolic BP greater than 90 or less than 50 mmHg at screening and Day -1 Personal history or family history of congenital long QT syndrome and/or cardiac sudden death History of Gilbert's syndrome Participants who have had significant acute infection, e.g., influenza, local infection, acute gastrointestinal symptoms or any other clinically significant illness within two weeks of dose administration Any confirmed significant allergic reactions (urticaria or anaphylaxis) against any drug, or multiple drug allergies (non-active hay fever is acceptable) Taking any herbal medications or substances (e.g., tea) or supplements (including vitamins), or traditional Chinese medicines (TCM) or over-the-counter (OTC) medications within 14 days of first dosing or within 5 times the elimination half-life of the medication prior to first dosing, whichever is longer History of having received any systemic anti-neoplastic (including radiation) or immunemodulatory treatment (including systemic oral or inhaled corticosteroids) </=6 months prior to the first dose of study drug or the expectation that such treatment will be needed at any time during the study Are currently enrolled in or have participated in any other clinical study involving an investigational product or in any other type of medical research within the last 30 days or 5 half lives (whichever is longer) Donation or loss of blood or blood products in excess of 500 mL within 3 months of screening and for the duration of the study Positive test for drugs of abuse (including recreational drugs) and/or positive alcohol test and/or positive cotinine test at screening and on Day -1 Positive test at screening of any of the following: Hepatitis A virus (HAV IgM Ab), hepatitis B virus (HBsAg or HBcAb), hepatitis C virus (HCV RNA or HCV Ab) or human immunodeficiency virus (HIV-1 and HIV-2 Ab) History of alcohol consumption exceeding 2 standard drinks per day on average (1 standard drink = 10 grams of alcohol) and/or drug abuse within 12 months of screening Use of >5 cigarettes or equivalent nicotine-containing product per day prior to screening

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Adverse Events (AEs) | An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. | From the start of Period 1 through safety follow-up (Period 2, Day 34) |
