NCT06099873•Nanjing Zenshine Pharmaceuticals

View on ClinicalTrials.gov

Summary

The primary object of this study is evaluating the efficacy of ZX-7101A tablets versus placebo in the treatment of uncomplicated simple influenza in adolescents. The seongdary object is evaluating the safety of ZX-7101A tablet in the treatment of uncomplicated simple influenza in adolescents.

Detailed Description

In this study, adolescents aged 12 and \< 18 with uncomplicated influenza are selected as subjects. Typical systemic and/or respiratory influenza symptoms were required, and the time interval between the first onset of influenza symptoms and random enrollment was less than 48 hours. This study is divided into screening/treatment period (D1) and observation period (about 2 weeks). You will be eligible before starting study therapy on day 1 (D1). Participants were randomly assigned 1:1 to ZX-7101A group (dose 40 mg, administration once) or placebo group (dose 1 placebo tablet, administration once), with 180 participants planned to be included in each group, for a total of about 360 participants.
