Brief Summary:
This study is a global multicenter, randomized, double-blind, placebo -controlled, adaptive designed phase Ⅲ clinical trial, in order to evaluate the efficacy, safety and immunogenicity of Recombinant Novel Coronavirus Vaccine (Adenovirus Type 5 Vector) in adults 18 years old and above.

Condition or disease Intervention/treatment Phase
COVID-19 Biological: Recombinant Novel Coronavirus Vaccine (Adenovirus Type 5 Vector) Biological: Placebo Phase 3

Detailed Description:

This is a global phase III clinical trial to evaluate efficacy,safety, immuogenicity of Ad5-nCoV manufactured by Cansino and Beijing Institute of Biotechnology in health adults aged 18 years old and above.

The study will be double-blind, placebo-controlled trial with participants randomly allocated 1:1 to placebo and experimental vaccine cohorts.

The immunization schedule is one doses intramuscular injections (deltoid).

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence of COVID-19 cases [ Time Frame: day 28 to 12 months post vaccination ]
    The efficacy of Ad5-nCoV in preventing virologically confirmed (PCR positive) COVID-19 disease

  2. Incidence of SAE [ Time Frame: Within 12 months ]
    Evaluate the incidence of severe adverse events (SAE)


Secondary Outcome Measures :
  1. Incidence of severe COVID-19 cases [ Time Frame: Day 14 to 12 months post vaccination ]
    Evaluate the efficacy of Ad5-nCoV in preventing severe COVID-19 disease caused by SARS-CoV-2 infection

  2. Incidence of solicited adverse reactions [ Time Frame: Day 0-7 post vaccination ]
    Incidence of solicited adverse reactions within 7 days after vaccination, in a subset

  3. Incidence of unsolicited adverse events [ Time Frame: Day 0-28 post vaccination ]
    Incidence of unsolicited adverse events within 28 days after vaccination in a subset

  4. Immunogencity of S-RBD IgG antibody (ELISA method) [ Time Frame: Day 28 post vaccination ]
    The seroconversion rate of S-RBD IgG antibody post vaccination

  5. Immunogencity of neutralizing antibody [ Time Frame: Day 28 post vaccination ]
    The seroconversion rate of neutralizing antibody

  6. Cell-mediated immune profile [ Time Frame: Day 28 post vaccination ]
    Number of cell-mediated immune response against SARS-CoV-2
