Detailed Description
This is a Phase 1, 2 part, fixed-sequence open-label, crossover study to evaluate the potential CYP1A2-mediated drug-drug interactions (DDI), safety, and tolerability of ABX464 combined with a known CYP1A2 substrate (caffeine) and a known CYP1A2 inhibitor (fluvoxamine).
Sixty (60) healthy adult male and female subjects 18 to 55 years of age are planned to participate in the study.
Separate cohorts of subjects will be enrolled for Part A (24 subjects) and Part B (36 subjects).

- Subject with a body mass index (BMI) of 18.5-30 kilogrammes per square metre (kg/m²).
- No clinically significant history of previous allergy / sensitivity to ABX464 or any of the excipients within the IMP.

- Donation of 450 millilitres (mL) or more blood within the 3 months before the first dose of IMP.
- Users of nicotine products i.e., current smokers or ex-smokers who have smoked within 6 months prior to first dose administration with the study medication or users of cigarette replacements (i.e., e-cigarettes, nicotine patches or gums).
- Total serum bilirubin, alkaline phosphatase (ALP), aspartate transaminase (AST) / serum glutamic-oxaloacetic transaminase (SGOT) and alanine transaminase (ALT) / Serum glutamic pyruvic transaminase (SGPT) > 1.5 x upper limit of normal (ULN).
Experiences regular headaches (i.e., experiences headaches more than weekly).
Part B Only:
- Meets Diagnostic and Statistical Manual of Mental Disorders (5th Edition) criteria for moderate or severe substance use disorder within 6 months before Screening.
- Reports having experienced suicidal ideation (Type 4 or 5 on the Columbia-Suicide Severity Rating Scale [C-SSRS]) within 30 days prior to Screening, any suicidal behaviour within 2 years prior to Screening (Any "Yes" answers on Suicidal Behaviour section of C-SSRS), and/or the Investigator assesses the subject to be a safety risk to him/herself or others;
- Clinically significant history of depression or anxiety.

Other: Evaluation of CYP1A2 inhibition and induction potential by ABX464
Using a fixed-sequence crossover study design, the Pharmacokinetics (PK) of caffeine (50 milligrams (mg) single oral dose) will be evaluated in the absence and presence of ABX464 (50 mg once daily for 14 days) in 24 healthy subjects.
Caffeine will be administered on Day 1 in the absence of ABX464, on Day 4 simultaneously with ABX464 to evaluate potential CYP1A2 inhibition by ABX464, and on Day 17 simultaneously with ABX464 following 14 days of once daily dosing of ABX464 to evaluate potential CYP1A2 induction by ABX464.

Other: Evaluation of ABX464 as a substrate for CYP1A2
