A Study of AK0529 to Evaluate Pharmacokinetics and Safety in Chinese Healthy Volunteers
A Study of AK0529 to Evaluate Pharmacokinetics and Safety in Chinese Healthy Volunteers
This study will characterize the pharmacokinetics (PK) of AK0529, the effect of food and
 evaluate the safety of AK0529 in healthy Chinese adult subjects. 50 subjects will be
 randomized to receive a dose level of AK0529 or placebo in five groups. The total study
 duration will be approximately 18-27 days for each subject.
This is a randomized, double-blind, placebo-controlled, single-center, Phase I study in
 healthy Chinese subjects. The objectives of the study are to evaluate the safety of AK0529,
 characterize the PK of AK0529 and to evaluate the effect of food in healthy Chinese subjects.
 50 healthy Chinese subjects will be randomized to orally receive one of four dose levels of
 AK0529 (single dose:100 mg and 300 mg, Multiple dose: 600 mg, Cross-over Food Effect: 300 mg)
 or placebo. The total duration of the study will be approximately 18 to 27 days for each
 subject.
Inclusion Criteria:

 -  Male or female participants between 18 and 45 years of age, inclusive.

 -  Have a body weight ≥45 kg (Female) or ≥50 kg (Male), and a body mass index (BMI)
 between 19 and 26 kg/m^2, inclusive.

 -  Participants are in good health without any significant clinical abnormalities as
 determined by the investigator on the basis of medical history, physical examination
 (including vital signs) and baseline test results (hematology, blood chemistry, blood
 coagulation, urinalysis and 12-lead electrocardiogram (ECG)).

 -  Participants and the spouses who are willing to use a medically accepted method of
 contraception (e.g. placement of an intrauterine device or intrauterine system,
 contraceptive drugs, using condom) during the study period and for one month
 thereafter.

 -  Participants who are willing to sign and date the approved informed consent form
 (ICF).

 Exclusion Criteria:

 -  Female subjects of childbearing potential have positive serum pregnancy test results
 or are lactating at screening.

 -  Subjects who have their daily cigarette smoking to five or more for 3 months prior to
 screening.

 -  History of severe or multiple drug allergies.

 -  History of alcohol abuse in the past 3 months prior to screening (Alcohol consumption
 >14 units per week: 1 unit = 10 mL alcohol, 250mL of 4 degrees beer, 25 mL of 40
 degrees spirit or 75 mL of 13 degrees wine).

 -  History of any drug abuse, or have a positive urine drug screen result at screening,
 or history of any psychotropic medication abuse within 5 years prior to screening.

 -  Previous exposure to any other Investigational Medicinal Product (IMP) or
 participation in any clinical trial within 3 months prior to screening.

 -  Donation or loss of blood over 450 mL within 3 months prior to screening.

 -  Use of any prescription, over-the-counter, herbs, or medications which can change the
 pH values of gastrointestinal tracts (e.g. antacids, H2 receptor inhibitors and/or
 proton-pump inhibitors) within 28 days prior to screening.

 -  Receiving caffeine-containing food or drinks, or alcohol-containing products within 24
 hours prior to study drug administration.

 -  Smoking and use of any nicotine-containing products within 24 hours prior to study
 drug administration.

 -  Have swallowing problems, or any gastrointestinal diseases or history of surgery (e.g.
 subtotal gastrectomy) that could possibly affect drug absorption.

 -  Clinically relevant abnormalities in the ECG results.

 -  Clinically significant abnormalities in the lab test results of biochemistry,
 hematology, blood coagulation or urinalysis above the upper limit of normal (ULN)
 ranges as judged by the investigator.

 -  Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab),
 human immunodeficiency virus (HIV-1 or HIV-2 antibody) or syphilis results.

 -  Evidence of clinical significant digestive, urological, neurological,hematological,
 endocrine, oncological, pulmonary, immunological, cardiovascular, or psychiatric
 disease at screening.

 -  ECG results with the QT interval, corrected for heart rate by Bazett's formula (QTcB)
 of > 450 msec in the supine position at screening.

 -  Systolic blood pressure (SBP) > 140 mmHg or < 90 mmHg, and/or diastolic blood pressure
 (DBP) > 90 mmHg or < 60 mmHg in the seated position at screening.

 -  Subjects are lactose intolerant.

 -  Inability to meet the study requirements in the opinion of the investigator.
