About this study

Official title: A Phase I Study to Determine the Safety and Immunogenicity of the Candidate Middle East Respiratory Syndrome Coronavirus (MERS-CoV) Vaccine ChAdOx1 MERS in UK Healthy Adult Volunteers

This is a clinical trial in which healthy volunteers will be administered an experimental MERS vaccine. The vaccine ChAdOx1 MERS will be administered alone both as a single administration and with a homologous prime-booster.

Read the detailed description

All vaccinations will be administered intramuscularly. In Groups 1-3, each volunteer will receive one vaccination in total. In Groups 4 and 5, each volunteer will receive two vaccinations in total.

There are five different vaccine schedules:

Group 1 (n=6) will receive 5 x 10^9 vp ChAdOx1 MERS .

Group 2 (n=9) will receive 2.5 x 10^10 vp ChAdOx1 MERS.

Group 3 (n=9) will receive 5 x 10^10 vp ChAdOx1 MERS.

Group 4 (n=6-12) will receive 2.5 x 10^10 vp ChAdOx1 MERS at week 0 followed by a boost of 2.5 x 10^10 vp ChAdOx1 MERS at week 26.

Group 5 (n=6-12) will receive 2.5 x 10^10 vp ChAdOx1 MERS at week 0 followed by a boost of 2.5 x 10^10 vp ChAdOx1 MERS at week 4.

The study will assess the safety of the vaccines, and the immune responses to the vaccinations. Immune responses are measured by tests on blood samples.

Healthy adult volunteers will be recruited in Oxford, England.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ChAdOx1 MERSBiological

    The ChAdOx1 MERS vaccine consists of the replication-deficient simian adenovirus vector ChAdOx1, containing the MERS Spike protein antigen.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Occurrence of solicited and unsolicited local and systemic adverse events

    The specific endpoints for safety and reactogenicity will be actively and passively collected data on adverse events. Change from baseline for safety laboratory measures will also be collected. Occurrence of serious adverse events will be collected during the whole study duration

    Measured: up to 28 days following vaccination

Secondary outcomes (1)
  1. Measures of immunogenicity to the ChAdOx1 MERS vaccine

    ELISA to quantify antibodies to MERS Spike protein antigen Ex vivo ELISpot responses to MERS Spike protein antigen

    Measured: 12 months

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted16 Jan 2018
  2. Study start14 Mar 2018
  3. Primary completion17 Sep 2021
  4. Study completion17 Sep 2021

Why it stopped: The scientific questions proposed remain relevant, but will now be addressed in a larger phase II immunogenicity trial of the ChAdOx1 MERS vaccine given at 2 doses.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ChAdOx1 MERS in people with MERS (Middle East Respiratory Syndrome), run by University of Oxford at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: The scientific questions proposed remain relevant, but will now be addressed in a larger phase II immunogenicity trial of the ChAdOx1 MERS vaccine given at 2 doses.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of solicited and unsolicited local and systemic adverse events (time frame: up to 28 days following vaccination). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03399578, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2021.
