- 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.

- Receipt of live vaccination within 30 days of dosing or plan to receive live vaccination during the study.
- Use of prescription drugs or non-prescription drugs, including non-steroidal anti inflammatory drug (NSAIDs), within 7 days prior to dosing, if in the opinion of the Investigator (in consultation with the GlaxoSmithKline [GSK] Medical Monitor if required) the medication will interfere with the study procedures or compromise participant safety.
- The participant has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day of the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
