Brief summary: This is a single center, randomized, double-blind, placebo-controlled, dose escalation study in healthy subjects to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of ICP-022 following oral single and multiple escalating dose administration.

Detailed description: This is a single center, randomized, double-blind, dose escalation, placebo-controlled, first-in-humans phase 1 study to investigate the safety and tolerability of single and multiple escalating doses of ICP-022 in healthy volunteers. 40 healthy male participants (aged between 18 and 55 years of age inclusive) will be enrolled into Part 1 (single escalating dose administration) of this study, and additional 24 male subjects will be enrolled in Part 2 (multiple escalating dose administration). Part 1a consists of 5 cohorts of 8 participants each, while Part 2 includes 3 cohorts of 8 participants each.

Part 1a consists a treatment period with single oral dosing, and a safety follow-up to 7 days after dosing. Cohort 4 of Part 1a will return on Day 8 to repeat the study under fed condition in Part 1b.

Part 2 consists a treatment period with multiple dosing (once per day for 14 consecutive days), and a safety follow-up until 28 days after dosing. All subjects will receive either ICP-022 or placebo.

Subjects must be willing to use a condom during sexual intercourse whether or not their partner is of child-bearing potential from screening until 90 days after their final study visit.
* Normal electrocardiogram (ECG), blood pressure, and heart rate, unless the investigator considers any abnormality to be clinically irrelevant

* Positive test for human immunodeficiency virus (HIV)
* Positive test for hepatitis B (surface antigens HBs), or C (antibody HCs), unless caused by immunization
* Positive urine drug screen within 1 year before randomization
* Positive alcohol screen or active alcoholism
* Mental condition rendering the subject incapable to understand the nature, scope, and possible consequences of the study
* Subject has difficulty swallowing or is unable to swallow a tablet
* Unlikely to comply with the clinical study protocol eg, uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study
* Investigator, or any sub-investigator, research assistant, pharmacist, study coordinator, other staff directly involved in the conduct of the protocol, or first degree relative thereof
* Subject requires anticoagulation treatment in the past 30 days
