Official title

A Single-Center, Double-Blind, Placebo-Controlled, Dose-Escalating Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, and QT Interval Effects of Oral FXS5626 Tablets in Healthy Chinese Participants

Overview

The purpose of this study is to evaluate the Exposure-Response Relationship Between the Plasma Drug Concentrations and the Change From Baseline in QTc interval of a single oral dose of FXS5626 in healthy subjects.

Interventions

  • Drug FXS5626 tablet
    FXS5626 75mg、250mg、400mg, single dose, oral
  • Drug Placebo tablet
    single dose, oral

Primary outcome measures

  • Effect on QTcF between baseline and post-dose treatment of FXS5626 [Time frame: 45 min before administration and 24 hours after administration]
  • To access the incidence and severity of adverse events (AEs), serious AEs and abnormalities on laboratory tests [Safety and Tolerability] of single ascending oral dose of FXS5626 in healthy adults. [Time frame: Approximately 1 week]
Secondary outcome measures (1)
  • Plasma concentration and pharmacokinetic parameters [Time frame: 10 min before administration and 48 hours after administration]
