June 30, 2020 updated by: CanSino Biologics Inc.
A Randomized, Observer-Blind, Dose-escalation Phase I/II Clinical Trial of Ad5-nCoV Vaccine in Healthy Adults From 18 to <85 Years of Age in Canada
This study is a phase I /II adaptive clinical trial to evaluate the safety, tolerability and the Immunogenicity of Ad5-nCoV in healthy adults from 18 to <55 and 65 to <85 years of age,with the randomized, observer-blind, dose-escalation design

Detailed Description
A total of 96 healthy adult volunteers will be vaccinated in phase I stepwised according to the dose-escalation design from the younger adults(18 to <55) to the older adults(65 to <85).
There are 2 dosage level used in this phase: 5E10vp and 10E10vp, and 2 dose schedules: single dose and 2 dose.
According to the pre-defined adaptive design standards, the trial will moved from Phase I to Phase II.
In the phase II portion, A total of 600 healthy adult volunteers will be vaccinated according to the dose-escalation design from the younger adults(18 to <55) to the older adults(55 to <85).
There are 2 dosage levels and schedules used in this phase,and will determine a final dose and schedule by the end.
Some cohorts in the phase II trial will be included in the subsequent phase III trial.
