adequate compliance with study therapy or to increase the risk of developing
pancreatitis or chemical hepatitis;

- Proven or suspected acute hepatitis in the 30 days prior to study entry;

- Intractable diarrhea (=6 loose stools/day for at least 7 consecutive days) within 30
days prior to study entry;

- Inability to swallow capsules;

- Presence of cardiomyopathy (due to any cause) or any significant cardiovascular
disease, such as unstable ischemic heart disease;

- Known, clinically significant cardiac conduction system disease.

- Baseline laboratory values measured within 2 weeks prior to initiating study drugs as
follows:

1. calculated creatine clearance <60 mL/min as estimated by the Cockcroft-Gault
equation;

2. total serum lipase = 1.4 times the upper limit of normal;

3. liver enzymes (AST, ALT) = 5 times the upper limit of normal;

4. total serum bilirubin = 1.5 times the upper limit of normal.

- Hypersensitivity to any component of the formulation of study drug;

- Prohibited therapies;

- Any other clinical conditions or prior therapy that, in the opinion of the
Investigator, would make the participant unsuitable for study or unable to comply with
the dosing requirements;
