Study Overview
=================
Brief Summary
-----------------
This is a Phase I Randomized,Double-Blind,Placebo-controlled Trial in Healthy Male Voluteers To Examine the Safety,Tolerability,and Pharmacokinetics of HMPL-011 After A Single Dose.

Detailed Description
-----------------
Eligible subjects will randomly recieve 1200 mg tablets (600 mg tablet X 2) or 1200 mg capsules (200 mg capsule X 6) of HMPL-011 under fed and fed circumstance in part 1. In part 2, eight subjects will be enrolled and given 800 mg tablets (400 mg/tablet X 2) every 8 hours daily for 6 days (morning dose only on Day 6).
