Description of intervention(s) / exposure
Subjects fulfilling the eligibility criteria will be enrolled sequentially into one of two cohorts, to receive either AK0529 and itraconazole or AK0529 and fluoxetine. A total of 28 healthy volunteers will be enrolled, 14 in each cohort. The two cohorts are parallel cohorts investigating the effect of multiple doses of itraconazole and fluoxetine on the PK parameters of a single dose of AK0529, respectively.
Subjects in Cohort 1 will receive a single oral dose of AK0529 on Day 1 and, after a wash-out period of 4 days a single oral dose of itraconazole once daily on Days 5-12, with co-administration of AK0529 on Day 8. Subjects will be admitted to the clinical research unit (CRU) on Day -1 before AK0529 dosing and remain in the CRU for a period of 21 days, during which the study personnel will dispense drugs on each administration day and monitor the subject's adhernece to study interventions, until all safety assessments have been completed on Day 20.
Subjects in Cohort 2 will receive a single oral dose of AK0529 on Day 1 and, after a wash-out period of 4 days a single oral dose of fluoxetine once daily on Days 5-17, with co-administration of AK0529 on Day 14. Subjects will be admitted to the CRU on Day -1 before AK0529 dosing and remain in the CRU for a period of 26 days, during which the study personnel will dispense drugs on each administration day and monitor the subject's adhernece to study interventions, until all safety assessments have been completed on Day 25.
The detailed treatment drugs information is as below:
1. AK0529 (Ziresovir)
100mg/capsule, oral administration
2. Itraconazole
Oral solution, 10mg/ml, 20ml (200mg)

Incidence rates of adverse events (AEs) prior to, during, and after administration of treatments. Adverse events can be spontaneously reported by the subject, observed by the Investigator (either directly or by laboratory or other assessments) or elicited by general questioning. For example, headache and dizziness can be assessed via subject’s self-report, while blood creatinine phosphokinase increased can be assessed via laboratory results.

Summary
Brief summary
This Phase I study will evaluate the drug-drug interaction of the investigational medicinal and substrate product AK0529, when administered with either itraconazole, a strong cytochrome P450 3A4 and P-glycoprotein inhibitor (Cohort 1) or fluoxetine, a strong cytochrome P450 2D6 (Cohort 2) inhibitor in healthy adult subjects. The primary objective of this study is to evaluate the effect of multiple doses of itraconazole and fluoxetine on the pharmacokinetics of a single dose of AK0529. This is a two part, open-label, fixed sequence study to be conducted at a single clinical research centre.
