• Percentage of Subjects with Adverse Events (AEs)

  An adverse event can be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product.

  From baseline up to approximately 6 weeks

Study Arms (6)

AK0529 100 mg, Pilot

EXPERIMENTAL

This is an open pilot arm and male subjects enrolled into this arm will be only administered with an oral single dose of 100 mg AK0529. The dose group begins treatment on Day 1.

Drug: AK0529

AK0529 100 mg

EXPERIMENTAL

Subjects will be administered with an oral single dose of 100 mg AK0529 or placebo. The dose group begins treatment on Day 1.

Drug: AK0529; Other: Placebo

AK0529 300 mg, food effect

EXPERIMENTAL

A 3x3 cross-over study is designed in this group to evaluate the food effect following a standard Chinese meal or a high fat meal in the same subjects, comparing with the PK profile of AK0529 under fasted condition. Subjects will be administered with an oral dose of 300 mg AK0529 or placebo on Day 1 of each cycle.

Drug: AK0529; Other: Placebo

AK0529 600 mg

EXPERIMENTAL

Subjects will be administered with an oral single dose of 600 mg AK0529 or placebo. The dose group begins treatment on Day 1.

Drug: AK0529; Other: Placebo

AK0529 300 mg, MAD

EXPERIMENTAL

Subjects will be administered with the multiple doses of 300 mg AK0529 or placebo on Day 1-7.

Drug: AK0529; Other: Placebo

Placebo

OTHER

For assessment of the Adverse Event (AE) profile, there are placebo controls in each dose group (except the pilot group). The placebo is administered at the same time (and of the same dosage) as the AK0529 subjects.

Other: Placebo
