Participants who are pregnant or breastfeeding. Participants should not be enrolled if they plan to become pregnant during the time of study participation; 5. Positive results of screening for drugs of abuse; 6. Evidence or history of clinically significant uncontrolled hematological, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, metabolic, systemic, infectious, or allergic disease (including drug hypersensitivity or allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing); 7. General anesthesia within 3 months before administration; 8. Major surgery within 28 days prior to randomization or major surgery planned during the next 6 months. For Renally Impaired Participants: 9. History of renal transplant; 10. Evidence of an unstable clinically important medical condition other than impaired renal function; 11. Acute exacerbation or unstable renal function, as indicated by worsening of clinical and/or laboratory signs of renal impairment, within the 4 weeks before study drug administration; 12. Participants undergoing any method of dialysis or hemofiltration; 13. Disorders or surgery of the gastrointestinal tract which may interfere with drug absorption or may otherwise influence the pharmacokinetics of the investigational medicinal product (e.g., inflammatory bowel disease, resections of the small or large intestine, etc.); 14. History of febrile illness within 5 days prior to dosing; 15.
