Brief summary: The purpose of this study is to evaluate the safety and tolerability of a single dose of HMPL-689 in healthy volunteers To determine the pharmacokinetic profile of single oral doses of HMPL-689 in healthy volunteers

Detailed description: Subjects will receive a single dose of HMPL-689 or matching placebo during Day 1. The planned dose levels are: 1, 2.5, 5, 10, 20, 25 and 30 mg (about 7 cohorts of 8 subjects). In each dose cohort, 8 subjects will be randomized to receive HMPL-689 (6 subjects) or placebo (2 subjects) under fed condition with a standard meal.

For the first dose Cohort (1 mg), a sentinel group of 2 subjects (1 HMPL-689 and 1 placebo) will be dosed 24 hours prior to the planned dosing of the remaining six subjects. The decision of dose escalation or study termination will be made jointly by the principal investigator and the sponsor based on the clinical data (safety, tolerability, available PK data and clinical laboratory values). Any dose level may be repeated, reduced or split into 2 doses if deemed appropriate by the Principal Investigator and Sponsor's medical Expert.

13. Presence or sequelae of gastrointestinal, liver or kidney disease, or other conditions known to interfere with the absorption, distribution, metabolism, or excretion of drugs
14. Chronic constipation or diarrhea, irritable bowel syndrome, inflammatory bowel disease, hemorrhoids or anal diseases with regular or recent presence of blood in feces
15. History of significant allergic disease (e.g. allergic to medications) and acute phase of allergic rhinitis in the previous 2 weeks before randomization/ enrollment or any food allergy
16. Clinically significant history of liver disease, including cirrhosis, current alcohol abuse, or current known active infection with HIV, hepatitis B virus (HBV), or hepatitis C virus (HCV)
17. Current evidence of drug abuse or history of drug abuse within one year before randomization/ enrollment
18. Mental condition rendering the subject incapable to understand the nature, scope, and possible consequences of the study
19. Unlikely to comply with the clinical study protocol; e.g. uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study
20. Subject is the investigator or any sub-investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the protocol
