Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Part A (SAD) Within each group, subjects will be randomised in a 3:1 ratio to receive either AM1476 (n=6) or placebo (n=2). The first 2 subjects in each group will be dosed in a sentinel fashion; 1 subject will receive AM1476 and the other will receive placebo as randomised.

Part B (MAD) Within each group, subjects will be randomised in a 3:1 ratio to receive either AM1476 (n=6) or placebo (n=2).
Primary purpose: TREATMENT

Brief summary: This is a First in Human (FIH), double-blind, randomised, placebo-controlled study designed to evaluate safety, tolerability and pharmacokinetics (PK) of single and multiple ascending oral doses of AM1476 in healthy subjects.

Detailed description: Part A (SAD); In the SAD part of the study, single oral doses of AM1476 will be administered in up to 9 sequential groups, each consisting of 8 subjects randomised to receive either AM1476 or placebo in a 3:1 ratio. The first 2 subjects in each group will be dosed in a sentinel fashion, 1 subject will receive AM1476 and the other will receive placebo as randomised.

Part B (MAD); The MAD part of the study will explore multiple ascending dosing of AM1476 for 10 days. AM1476 will be administered in up to 6 sequential groups, each consisting of 8 subjects randomised to receive either AM1476 or placebo in a 3:1 ratio.

Eligibility criteria: Inclusion Criteria:

1. Males or females, of any race, between 18 and 60 years of age, inclusive.
2. A body mass index (BMI) between 18.0 and 32.0 kg/m2, inclusive.
3. In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital signs measurements, and clinical laboratory evaluations (congenital non-haemolytic hyperbilirubinemia \[eg, suspicion of Gilbert's syndrome based on total and direct bilirubin\] is not acceptable) at Screening and/or Check-in (Day -1) as assessed by the Investigator (or designee).
4. Females will not be pregnant or lactating, and females of childbearing potential and males will agree to use contraception as detailed in Appendix 4.
5. Able to comprehend and willing to sign an ICF and to abide by the study restrictions.

Exclusion Criteria

1. Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, haematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the Investigator (or designee).
2. History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the Investigator (or designee).
3. History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (uncomplicated appendectomy and hernia repair will be allowed).
4. Any of the following observed in at least 2 of 3 ECG measurements performed:

   1. QTcF \> 450 msec.
   2. QRS duration \> 110 msec.
   3. PR interval \> 220 msec.
   4. findings which would make QTc measurements difficult or QTc data uninterpretable.
5. Any history of additional risk factors for torsades de pointes (eg, heart failure, hypokalaemia, family history of long QT syndrome).
6. Any history or current controlled or uncontrolled hypertension or systolic blood pressure \> 140 mmHg or diastolic blood pressure \> 90 mmHg confirmed by repeat measurement.
7. History of alcoholism or drug/chemical abuse within 2 years prior to Check-in (Day -1).
8. Alcohol consumption of \> 21 units per week for males and \> 14 units per week for females. One unit of alcohol equals ½ pint (285 mL) of beer or lager, 1 glass (125 mL) of wine, or 1/6 gill (25 mL) of spirits.
9. Positive alcohol breath test result or positive urine drug screen (confirmed by repeat) at Screening or Check-in (Day -1).
10. Positive hepatitis panel and/or positive human immunodeficiency virus test (Appendix 2).
11. Participation in a clinical study involving administration of an investigational drug (new chemical entity) in the past 90 days prior to dosing.
12. Use or intend to use any medications/products known to alter drug absorption, metabolism, or elimination processes, including St. John's Wort, within 30 days prior to dosing, unless deemed acceptable by the Investigator (or designee).
13. Use or intend to use any prescription medications/products other than hormone replacement therapy, oral, implantable, transdermal, injectable, or intrauterine contraceptives within 14 days prior to dosing, unless deemed acceptable by the Investigator (or designee).
14. Use or intend to use slow release medications/products considered to still be active within 14 days prior to Check-in (Day -1), unless deemed acceptable by the Investigator (or designee).
15. Use or intend to use any non-prescription medications/products including vitamins, minerals, and phytotherapeutic/herbal/plant-derived preparations within 7 days prior to Check-in (Day -1), unless deemed acceptable by the Investigator (or designee).
16. Use of tobacco- or nicotine-containing products within 3 months prior to Check-in (Day -1) or positive cotinine at Screening or Check-in (Day -1).
17. Ingestion of poppy seeds, Seville orange, or grapefruit-containing foods or beverages within 7 days prior to Check-in (Day -1).
18. Subjects who are vegetarians, vegans, or are unable to consume the high-fat breakfast (subjects who will participate in a food-effect evaluation only).
19. Receipt of blood products within 2 months prior to Check-in (Day -1).
