Volunteers with ALP and/or ALT/AST above the limits specified may be included, at the discretion of the Investigator, if the levels are unaccompanied by clinical signs and are determined to be normal variants
- Positive test results for active human immunodeficiency virus (HIV-1 or HIV-2), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV) antibodies at the screening visit
- Presence or having sequelae of gastrointestinal, liver (including Gilbert’s syndrome), kidney, or other conditions known to interfere with the absorption, distribution, metabolism, or excretion of drugs
- Estimated creatinine clearance (CrCl) less than 60 mL/min using the Cockcroft-Gault formula or serum creatinine more than 1.5-fold above the ULN
- History of substance abuse or alcohol abuse (defined as more than 10 standard drinks per week or regularly consuming more than 4 standard drinks on any one day; where 1 standard drink is 10 g of pure alcohol and is equivalent to 285 mL beer (4.9% Alc./Vol), 100 mL wine (12% Alc./Vol), 30 mL spirit (40% Alc./Vol) within 12 weeks prior to the screening visit
- Positive drugs of abuse or alcohol breath test results at the screening visit or at check-in (Day -1).
- Use of any prescription or over-the-counter medication (including herbal products, diet aids, and hormone supplements) within 10 days or 5 half-lives of the medication (whichever is longer) prior to the first study drug administration, except use of contraceptives and occasional use of paracetamol (doses of 500 mg up to every 6 hours or 2 g per day maximum for no more than 3 consecutive days)
- Consumption of grapefruit or Seville orange (or products containing grapefruit or Seville orange) within 10 days prior to the first administration of study drug
- Demonstrated clinically significant (required intervention, e.g., emergency room visit, epinephrine administration) allergic reactions (e.g., food, drug, or atopic reactions, asthmatic episodes) which, in the opinion of the Investigator, would interfere with the volunteer’s ability to participate in the trial
- Known hypersensitivity to any of the study drug ingredients
- Use of any vaccinations within 14 days prior to the first study drug administration
- For women of childbearing potential, a positive serum pregnancy test at the screening visit or a positive urine pregnancy test (with confirmatory serum pregnancy test) at check-in (Day -1)
- Females who are breastfeeding or planning to breast feed at any time during the study

- Any other condition or prior therapy that in the opinion of the Investigator would make the volunteer unsuitable for this study, including inability to cooperate fully with the requirements of the study protocol or likelihood of noncompliance with any study requirements

Interventions
This is a randomised, double-blind, placebo-controlled, ascending dose, multi-cohort study. The study will be conducted in 2 parts: a single ascending dose (SAD) part (Part A) followed by a multiple ascending dose (MAD) part (Part B). In part A, 64 healthy volunteers will be enrolled in a total of 8 cohorts testing single incremental doses of oral capsules at the following dose levels: 2mg, 5mg, 25mg, 50mg, 100mg, 200mg, 400mg and 600mg strengths of ANPA-0073. Each cohort will enrol 8 participants with 6 participants randomised to receive ANPA-0073 and 2 participants randomised to receive placebo. In addition, cohort 4 will be a food effect cohort: a single 50mg oral dose of ANPA-0073 or placebo will be administered on Day 1 under fasted conditions and another dose administered on Day 4 under fed conditions (total of 2 doses). Participants will receive a single 50mg oral dose of ANPA-0073 or placebo after consumption of a high-fat, high-calorie breakfast, based on the example meal provided in the US Department of Health and Human Services Food and Drug Administration Center for Drug Evaluation and Research (CDER) December 2002 Guidance for Industry – Food-Effect Bioavailability and Fed Bioequivalence Studies. Eg, Approximately 50 percent of the total calories of the meal are derived from fat and the meal is approximately 800 to 1000 calories. The meal should derive approximately 150, 250, and 500-600 calories from protein, carbohydrate, and fat, respectively. In part B, 32 healthy volunteers will be enrolled in a total of 4 cohorts to receive a once daily dose of ANPA-0073 or placebo for seven consecutive days. Up to 4 dose levels (from 75 mg to 600 mg) will be evaluated in Part B. For Cohorts 1-4, ANPA-0073 dose administration will be once daily. The proposed dose for MAD cohort 1 is 75mg, MAD cohort 2 is 150mg, MAD cohort 3 is 300mg and MAD cohort 4 is 500mg. Each MAD cohort will enrol 8 participants with 6 participants randomised to receive ANPA-0073 and 2 participants randomised to receive placebo. In both parts, the SRC should make a recommendation as to whether the next dose should be escalated or reduced, or additional subjects should be dosed in a same dose level of a cohort. Cohorts will be separated by approximately 5 to 10 days from the last participant visit in one cohort to the first participant visit in the next cohort. The actual time between cohorts is dependent on the time taken to obtain safety and PK data for the SRC to review at the SRC meetings.
