Plain English Summary

Background and study aims
COVID-19 is a condition caused by the coronavirus (called SARS-CoV-2) that was first identified in late 2019. This virus can infect the respiratory (breathing) system. Some people do not have symptoms but can carry the virus and pass it on to others. People who have developed the condition may develop a fever and/or a continuous cough among other symptoms. This can develop into pneumonia. Pneumonia is a chest infection where the small air pockets of the lungs, called alveoli, fill with liquid and make it more difficult to breathe.
Valneva’s COVID-19 vaccine candidate is called VLA2001. The aim of this study is to compare the immune response to the VLA2001 vaccine to the AZD1222 vaccine in adults aged 30 and older, and to evaluate the safety and tolerability of VLA2001 in adults aged 18 and older.

Who can participate?
Adults aged 18 and older who have not received any COVID-19 vaccination yet, regardless of whether they had been infected by SARS-CoV-2 before or not. Please visit https://www.ukcovid19study.com for more information.

What does the study involve?
Participants are randomly allocated to receive either the VLA2001 or AZD1222 vaccine. The participants and treating doctors will not know which of the two vaccines will have been given. The aim is to compare the immune response and safety of the two vaccines, and to establish a robust safety database for VLA2001. Participants will receive VLA2001 at the dose selected based on the results of the first study. The vaccination schedule will be aligned between the two vaccines, i.e. vaccinations will occur on Days 1 and 29, and follow-up visits will be conducted for 1 year.

What are the possible benefits and risks of participating?
This is the second study in human participants and the clinical benefits of VLA2001 have not yet been established. Although the vaccine might induce immune responses that may be protective, participants might not experience any direct benefit from taking part in this study. The information obtained from this study may help prevent future participants from contracting COVID-19 and will provide important information about how well people respond to VLA2001. There may be risks to being in this study from the study vaccine or from some of the procedures or tests carried out in this study.

Where is the study run from?
Valneva (Austria)

When is the study starting and how long is it expected to run for?
July 2020 to June 2022

Who is funding the study?

Scientific titleA randomized, observer-blind, controlled, superiority study to compare the immunogenicity against COVID-19 of the VLA2001 vaccine and the AZD1222 vaccine in adults
Study acronymCOV-COMPARE
Study hypothesisThe purpose of this study is to compare the immunogenicity of the VLA2001 vaccine to the AZD1222 vaccine in adults aged 30 years and older; and to evaluate the safety and tolerability of VLA2001 in adults aged 18 years and older.
Ethics approval(s)Approved 20/04/2021, North West - Greater Manchester South Research Ethics Committee (3rd Floor, Barlow House, 4 Minshull Street, Manchester, M1 3DZ, UK; +44 (0)207 104 8221, +44 (0)207 104 8063; gmsouth.rec@hra.nhs.uk), REC ref: 21/NW/0125
ConditionCOVID-19 (SARS-CoV-2 infection)
InterventionAbout 3000 participants aged 30 years and above will be randomized via an Interactive Response System (IRS) in a 2:1 ratio to receive two intramuscular recommended doses of either VLA2001 (n=2000) or AZD1222 (n=1000). In addition, approximately 1000 subjects aged 18-29 years will participate in this study in a non-randomized, open-label fashion to receive VLA2001. The two doses of vaccination for both vaccines will be administered 28 days apart on Days 1 and 29.

Participants will be followed up in the study for approximately 11 months after their second vaccination.
Intervention typeBiological/Vaccine
Pharmaceutical study type(s)
PhasePhase III
Drug / device / biological / vaccine name(s)VLA2001, AZD1222
Primary outcome measureImmunogenicity:
1. Immune response after completion of a two-dose immunization schedule, as determined by the geometric mean titer (GMT) of SARS-CoV-2-specific neutralizing antibodies measured using a neutralization assay on Day 43

Safety:
2. Frequency and severity of any Adverse Events (AE) collected during study visits up to Day 43 post-vaccination
Secondary outcome measuresImmunogenicity:
1. Proportion of participants with seroconversion measured using a neutralization assay on Day 8 (age 55+ only), Day 29, Day 43, Day 71, Day 208 and Day 365
2. Immune response, as determined by the GMT of SARS-CoV-2-specific neutralizing antibodies measured using a neutralization assay on Day 8 (age 55+ only), Day 29, Day 71, Day 208 and Day 365
3. Immune response, as determined by the GMT of IgG antibodies to SARS-CoV-2 S-protein measured using an Enzyme-Linked Immunosorbent Assay (ELISA) on Day 8 (age 55+ only), Day 29, Day 43, Day 71, Day 208 and Day 365
4. T-cell responses assessed using T-spot assay and/or intracellular cytokine staining at selected timepoints (yet to be defined) in a subset of participants

Safety:
5. Frequency and severity of solicited injection site and systemic reactions captured using electronic diaries within 7 days after each and after any vaccination
6. Frequency and severity of any AE collected during study visits during the entire study period
