• Age 18 to 55 years of age
• Body mass index of 18.0 to 30.1 kg/m2
• Light smokers (less than 5 cigarettes per day) or subjects who are nonsmokers. No smoking (or use of smoking substitute e.g. nicotine patch) is permitted from screening throughout the study

• Must agree to use an adequate method of contraception
• Must, in the opinion of the investigator, be in good health based upon medical history and physical examination (including vital signs)

Exclusion criteria

• Subjects who have received of zoliflodacin or any IMP in a clinical research study within 5 half-lives or within 30 days prior to first dose. However, in no event, shall the time between last receipt of IMP and first dose be less than 3 months
• Subjects who are study site employees, or immediate family members of a study site or sponsor employee
• Subjects who have previously been enrolled in this study
• History of any drug or alcohol abuse in the past 2 years
• Regular alcohol consumption in males >21 units per week and females >14 units per week (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 Units = 125 mL glass of wine, depending on type)
• Subjects who have regular daily consumption of ≥5 cigarettes daily, or use more than 3 grams (1/8 ounce) of tobacco
• Excessive intake of caffeine (more than 8 cups daily of beverage containing caffeine)
• Subjects who have regular daily consumption of more than one liter of xanthine containing beverages
• Females of childbearing potential who are pregnant or lactating (female subjects must have a negative serum pregnancy test at screening and admission)
• Have poor venous access that limits phlebotomy
• Clinically significant abnormal biochemistry, hematology or urinalysis at screening (i.e. aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine and urea must be within normal ranges) as judged by the investigator at screening and admission (laboratory parameters are listed in Appendix 1)
• Presence of clinically significant abnormality following review of vital signs, full physical examination and ECG
• Positive drugs of abuse test result
• History or presence of any clinically significant acute or chronic disease, including known or suspected human immunodeficiency virus (HIV), HBV or HCV infection
• Evidence of renal impairment at screening, as indicated by an estimated creatinine clearance of <80 mL/min using the Cockcroft-Gault equation
• History of cardiovascular, renal, hepatic, chronic respiratory or GI disease, or psychiatric disorder, as judged by the investigator
• Any clinically important abnormalities in rate, rhythm, conduction or morphology of resting ECG that in the opinion of the PI are clinically significant or may interfere with the interpretation of QTc interval changes
• Presence of clinical condition or prior therapy which, in the opinion of the Investigator, made the subject unsuitable for the study
• Subjects who have had surgery (e.g. stomach bypass) or medical condition that might affect absorption of study drug taken orally
• History of GI ulcer disease, inflammatory bowel disease, indigestion symptoms >3 times a week, or blood in stool in previous 6 months not related to anal trauma
• Subjects who have had febrile illness within 1 week before the start of the study
• Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients
• Presence or history of clinically significant allergy requiring treatment, as judged by the investigator. Hayfever is allowed unless it is active
• Must not have significant serious skin disease, including rash, food allergy, eczema, psoriasis, or urticaria
• History of rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency
• History of major surgical procedure or have donated of blood within 12 weeks prior to first dose of study medication or plasma within 7 days prior to first dose of study medication
• Must not donate blood from clinic admission, throughout the study duration, and for at least 30 days following last dose of study medication
• Subjects who are taking, or have taken, any prescribed or over-the-counter drug, including antacid drug, (other than 4 g per day acetaminophen, hormone replacement therapy, hormonal contraception) in the 28 days before IMP administration. Exceptions may apply on a case by case basis, if considered not to interfere with the objectives of the study, as agreed by the PI and sponsor's medical monitor
• Use of dietary supplements or herbal remedies (such as St John's Wort), or grapefruit products known to interfere with the CYP3A4 and/or P-gp metabolic pathways during the 14 days before the first dose of trial medication
• Individuals who have been vaccinated within 4 to 6 weeks before dose administration of the IMP or planned to be vaccinated up to 4 to 6 weeks after dose administration of the IMP
• Failure to satisfy the investigator of fitness to participate for any other reason
