Basic Information

• Recruitment Status: NOT_YET_RECRUITING
• Clinical Phase: PHASE1
• Total Enrollment: 78 participants

Brief Summary

The goal of this clinical trial is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and food effect of single and multiple ascending doses of QLS1410 in healthy Chinese adults and participants with mild essential hypertension

Detailed Description

This study consists of three parts, as follows:

Part A is a randomized, placebo-controlled, double-blind single ascending dose (SAD) study in healthy Chinese adults, consisting of 5 cohorts. Starting dose of 0.5 mg by oral administration are planned. Once sufficient safety and PK data are obtained from the SAD cohorts, the SMC will determine the dosage of initial cohort in Part B and Part C.

Part B is a randomized, open-label, two-cycle, crossover food effect (FE) study under fasting and fed (high-fat meal) conditions.

Part C is a randomized, placebo-controlled, double-blind multiple ascending doses (MAD) study in participants with mild essential hypertension, consisting of 3 cohorts.

Study Groups

QLS1410

Part A: Healthy adults will be randomized (6:2) to receive a single dose (1.5 mg ~ 20 mg) of QLS1410 or placebo,especially, the starting dose will be 0.5 mg of QLs1410

Part B: QLS1410 will be administered under the fasted or fed conditions in two different periods separated by a wash-out interval of 14 days. The dose of QLS1410 or placebo is based on upcoming data from SAD part.

Part C: Hypertensive participants will be randomized (8:2) to receive QLS1410 or placebo QD for 14 continuous days. The starting dose of QLS1410 or placebo is based on upcoming data from SAD part.
