- Treatment of a chronic infection within 3 months prior to the first dose of study drug.
- Any acute infection (including upper respiratory tract infections and urinary tract infections) which has not fully resolved within four weeks of dosing
- History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy.
- Current or chronic history of liver disease or known hepatic or biliary abnormalities.
- Participants with a history of renal disease or renal abnormalities.
