Description of intervention(s) / exposure
This study will be conducted in four independent Parts as follow:
Part 1(Tinlarebant+Omeprazole): 12 participants will take tinlarebant (5 mg) on Day 1 and Day 22, and take Omeprazole(40 mg) once daily on each Day 18-26.
Part 2 (Tinlarebant+Itraconazole): 12 participants will take tinlarebant (5 mg) on Day 1 and Day 22, and take Itraconazole (200 mg) twice daily on each Day 17-26.
Part 3 (Tinlarebant+Rifampin): 12 participants will take tinlarebant (5 mg) on Day 1 and Day 22, and take Rifampin (600 mg) once daily on each Day 14-26.
Part 4 (Food Effect): 12 participants will be randomized into two treatment sequences:
Sequence 1: to take tinlarebant (5mg) on Day 1 under fasted condition, and Day 22 under fed condition.
Sequence 2: to take tinlarebant (5mg) on Day 1 under fed condition, and Day 22 under fasted condition.
- Fasted condition: minimum 10 hour fast, water allowed until 1 hour before study drug administration.
- Fed condition: participants will have a standard high fat, high calorie meal includes: 2 eggs fried in butter, 2 rashers of bacon, 2 slices of toast with 16 g butter per slice, 125 g of hash browns and 240 mL of full cream milk.
All the study drug all be administrated orally, and recorded in dosing diaries at home or Electronic Medical Record on site.

To investigate the safety and tolerability of tinlarebant, Safety endpoints include:
• Incidence, severity, and relationship of adverse events (AEs) and serious adverse events (SAEs) (including withdrawals due to AEs).
• Change from baseline in vital sign measurements (systolic and diastolic blood pressure (BP), heart rate (HR), respiratory rate, and body temperature).
• Change from baseline in electrocardiogram (ECG) parameters.
• Change from baseline in clinical laboratory parameters (haematology, coagulation, serum chemistry, and urinalysis).
Query!
Assessment method [2]
430194
0
Safety endpoints will be evaluated by performing physical examinations, vital signs measurements, ECGs, clinical laboratory tests, and monitoring AEs.
Full physical examinations will include, at a minimum, assessment of the following: General appearance, HEENT (includes head, ears, eyes, nose, throat), Neck (includes Thyroid and Nodes), Cardiovascular, Respiratory, Gastrointestinal, Renal, Neurological, Musculoskeletal, Skin and any other focused assessments suggested by the presence of specific symptoms.
Vital signs assessments will include systolic and diastolic blood pressure by blood pressure monitor, heart rate by 12-lead ECG, body temperature by thermometer (tympanic temperature accepted), and respiratory rate assessed as per clinical site standard ranges.
For clinical laboratory tests, blood samples for haematology, coagulation, and serum chemistry as well as urine samples for urinalysis will be collected.
Expected AEs from tinlarebant include delayed dark adaptation, xanthopsia and headache. Expected AE from those comedications are listed in their package insert, such as stomach pain, headache and dizziness. These will be monitored by PI via clinical examinations.
