A Study of HMPL-689 in Healthy Volunteers

Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: HMPL-689; Drug: HMPL-689 placebo

• Registration Number: NCT02631642
• Lead Sponsor: Hutchison Medipharma Limited

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.

Group	Intervention	Description
HMPL-689	HMPL-689	Subjects will receive a single dose of HMPL-689 or matching placebo on Day 1. The planned dose levels in ascending order are: 1, 2.5, 5, 10, 20, 25 and 30 mg (7 dose cohorts with 8 subjects in each cohort). Within each cohort, randomization ratio of 3:1 is followed to dose 6 subjects with HMPL-689 and 2 subjects with placebo.
