About this study

Official title: A Randomized, Single-blind, Placebo-controlled Clinical Trial to Evaluate the Efficacy and Safety of Anti-COVID-19 Antibody SA58 Nasal Spray, Among Close Contact With COVID-19 People

This is a randomized, single-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of SA58 nasal spray in close contact with COVID-19 people.

Read the detailed description

This study is a randomized, single-blind, placebo-controlled clinical trial in close contacts to COVID-19. The investigational drug was manufactured by Sinovac Life Sciences Co. , Ltd.The purpose of this study is to estimate the efficacy and safety of SA58 nasal spray in close contacts to COVID-19. A total of 2900 subjects were planned to be enrolled,including 2300 subjects who were non-continuous exposed to COVID-19 in group A,600 subjects who were continuous exposed to COVID-19 in group B. All subjects started medication on the day of enrollment. During the medication period, the subjects were given nasal spray once every 3 hours,about 5-6 times a day.

    Measured: Up to 30 days(during case surveillance period)

Secondary outcomes (6)
  1. Incidence of symptomatic COVID-19 cases confirmed by RT-PCR in subjects stratified by different Ct values at the time of diagnosis of primary cases(≤30, >30)

    Incidence of symptomatic COVID-19 cases confirmed by RT-PCR when groups were stratified according to different Ct values at the time of diagnosis of primary cases(≤30, >30) during case surveillance period.

    Measured: Up to 30 days (during case surveillance period)

  2. Incidence of symptomatic COVID-19 cases confirmed by RT-PCR in subjects stratified by actual dosing interval

    Measured: Up to 30 days (during case surveillance period)

  3. The infection rate of asymptomatic COVID-19 infected people confirmed by RT-PCR

    The infection rate of asymptomatic COVID-19 infected people confirmed by RT-PCR during the case surveillance period.

    Measured: Up to 30 days (during case surveillance period)

  4. The incidence rate of symptomatic COVID-19 cases (mild, normal, severe and critical)
