简要总结
To assess the safety and tolerability of single and multiple doses of HMPL004-6599 in healthy male volunteers
详细描述
This is a Phase I study with two parts:
Part A: Double blind, randomized, placebo-controlled, dose-escalating, single dose study in healthy volunteers.
Subjects will receive a single dose of up to 1800 mg HMPL004-6599 or matching placebo on Day 1. The planned dose levels are: 600, 1200, and 1800 mg under fed conditions with a standard meal, according to the randomization schedule. Dose levels may be repeated, or reduced if deemed appropriate by the Safety Monitoring Committee (SMC).
Part B: Double blind, randomized, placebo-controlled, dose-escalating, multiple dose study in healthy male volunteers.
Dose levels in Part B for 14 days are planned as 200mg TID, 400mg TID, 600mg BID and 600mg TID. These dose were jointly decided by the PI, SMC and the Sponsor based on the results from Part A. On day 14, only one dose in the morning will be administrated for all cohorts. Dose levels may be repeated, or reduced if deemed appropriate by the Safety Monitoring Committee (SMC).

主要结局
Incidence of Treatment-Emergent Adverse Events
时间窗: Part A: single dose; Part B: 21 days
A primary objective of this study is to assess the safety of a single dose of up to 1800 mg in Part A (evaluated in planned steps of 600, 1200, and 1800 mg HMPL004-6599 under fed conditions of a standard meal), followed by multiple doses of up to 1800mg in Part B (evaluated in planned steps of 200mg TID, 400mg TID, 600mg BID and 600mg TID HMPL004-599 under fed conditions of a standard meal for 14 days ) in healthy male volunteers. The occurrence of Serious Adverse Events and Adverse Events will be evaluated during the study in order to determine this primary objective.
Incidence of Participants with Abnormal Laboratory Values
时间窗: Part A: single dose; Part B: 21 days
A further primary objective of this study is to assess the tolerability of a single dose of up to 1800 mg in Part A (evaluated in planned steps of 600, 1200, and 1800 mg HMPL004-6599 under fed conditions of a standard meal), followed by multiple doses of up to 1800mg in Part B (evaluated in planned steps of 200mg TID, 400mg TID, 600mg BID and 600mg TID HMPL004-599 under fed conditions of a standard meal for 14 days ) in healthy male volunteers. The occurrence of abnormal laboratory values will be reviewed during the study in order to determine this primary objective.
