Study Description

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

Condition or disease	Intervention/treatment	Phase
Healthy Volunteers	Drug: HMPL-689; Drug: HMPL-689 placebo	Phase 1

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.

Arms and Interventions

Arm	Intervention/treatment
Experimental: 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.	Drug: HMPL-689; selective PI3Kδ inhibitor; Other Name: Huchison Medipharma
Placebo Comparator: HMPL-689 placebo; 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.	Drug: HMPL-689 placebo; placebo of HMPL-689; Other Name: Huchison Medipharma

Outcome Measures

Primary Outcome Measures :

1. dose limited toxicities evaluated with NCI CTCAE v4.03 [ Time Frame: within 28 days after the first dose ]
   Incidence of dose limited toxicities and associated dose of HMPL-689

Secondary Outcome Measures :

1. maximum plasma concentration calculated with Blood samples [ Time Frame: within 29 days after the first dose ]
   Blood samples will be taken to measure the levels of study drug
2. time to reach maximum concentration calculated with Blood samples [ Time Frame: within 29 days after the first dose ]
   Blood samples will be taken to measure the levels of study drug
