A Study to Evaluate Pharmacokinetics, Safety and Tolerability of Single and Multiple Intravenous Doses of N-acetylcysteine (NAC) in Chinese Healthy Volunteers

Zambon SpA24 enrolled

Overview

This is a single and multiple dose, single centre, open-label, one-way, pharmacokinetics, safety and tolerability clinical trial of Phase I to be performed in Chinese healthy male and female volunteers. Twenty-four (24) healthy male and female Chinese volunteers will be included in the study. Drop-out subjects will not be replaced. The study has been designed in agreement with the Chinese Technical Guideline on Clinical Pharmacokinetic Research of Chemical Drugs, 18 March 2005 and the European Guideline on the Investigation of Bioequivalence. No randomisation will take place in this study. All the participant will receive the same treatment with the investigational medicinal product (IMP), i.e. NAC, 300 mg/ 3 mL solution for injection.
