Phase 1, Open Label Study to Evaluate the Safety and Immunogenicity of ChAd68 and AdHu5 Vector-based Trivalent COVID-19 Vaccines Delivered Via Inhaled Aerosol
In Brief
A Phase 1 clinical trial evaluating Ad5-triCoV/Mac and ChAd-triCoV/Mac for COVID-19 and SARS-CoV2 Infection. Completed, enrolled 36 participants across 1 site.
Detailed Summary
This is a phase 1 study in healthy volunteers who have received at least three doses of an mRNA COVID-19 vaccine, to evaluate the safety and immune responses that develop in the blood and lungs following the administration by aerosol of either Ad5-triCoV/Mac or ChAd-triCoV/Mac, new experimental adenovirus-based vaccines expressing SARS-CoV-2 spike, nucleocapsid and RNA polymerase proteins.
Study Details
Timeline
Interventions
Ad5-triCoV/Mac is a recombinant type 5 human adenovirus vector which has been engineered to express our trivalent SARS-CoV-2 transgene cassette under the control of an MCMV promoter, and is followed by an SV40 polyA signal. The adenovirus construct is E1 and E3 deleted.This trivalent transgene cassette consists of the S1 region of SARS-CoV-2 spike protein (aa 47-716), full-length SARS-CoV-2 nucleoprotein (N) fused to a highly conserved portion of the SARS-CoV-2 polymerase (RdRp or POL).
ChAd-triCoV/Mac is an E1 and E3 deleted chimpanzee adenovirus serotype 68 where the trivalent SARS-CoV-2 transgene cassette is under the control of an HCMV promoter and is followed by an SV40 polyA signal. The trivalent transgene cassette consists of the S1 region of SARS-CoV-2 spike protein (aa 47-716), full-length SARS-CoV-2 nucleoprotein (N) fused to a highly conserved portion of the SARS-CoV-2 polymerase (RdRp or POL).
