Trial summary

Respiratory tract infections, e.g. caused by SARS-CoV-2, disproportionately affect elderly. Vaccination has shown to be the most cost-effective approach to prevent infections. However, older adults often fail to induce a potent immune response to vaccines, as was also seen recently for COVID-19 mRNA vaccines. Read more about this study

About this study

Respiratory tract infections, e.g. caused by SARS-CoV-2, disproportionately affect elderly. Vaccination has shown to be the most cost-effective approach to prevent infections. However, older adults often fail to induce a potent immune response to vaccines, as was also seen recently for COVID-19 mRNA vaccines. This is likely due to immune dysfunction as a consequence of aging. To potentiate a stronger immune response, vaccine administration into the papillary dermis (intradermal, ID) has been proposed as an alternative strategy to intramuscular (IM) administration.

Vaccination through the ID route has shown to be safe and equally or more effective than IM vaccination with a wide variety of vaccines. Recently, ID administration has been tested with two COVID-19 mRNA vaccines (Spikevax, Moderna and Comirnaty, Pfizer/BioNTech) in reduced (fractional) doses of the standard IM dose.

To ease ID administration and thereby facilitate the implementation of this route, silicon-based microneedles have been developed. These needles have shown to allow ID administration of the Spikevax vaccine with equal safety and immunogenicity profiles as the traditional Mantoux approach in young adults.

In the present study, we will investigate the immunogenicity of a 20 mcg dose of the COVID-19 mRNA Comirnaty vaccine through ID administration with silicon microneedles in elderly people (75 years and older), and compare this to immunogenicity of IM administration of a 20 mcg dose and a 30 mcg (standard IM) dose.

What is being measured

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

  1. Concentrations of SARS-CoV-2-Spike protein specific IgG antibodies in serum for the different intervention groups

    Measured: at 28 days after vaccination

Secondary outcomes (2)
  1. Titers of SARS-CoV-2 specific neutralising antibodies in serum of the different intervention groups

    Measured: at 28 days after vaccination

  2. The percentage of participants with local and systemic adverse events

    • Solicited adverse events (AEs): local reactions, reaction of regional lymph nodes, and systemic reactions up to 14 days following vaccination
    • Unsolicited AEs up to 28 days following vaccination
    • Serious AEs (SAEs) up to 28 days following vaccination
    • Use of antipyretics and analgesics up to 14 days following vaccination

    Measured: up to 28 days after vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Comirnaty in people with Vaccination; Infection and COVID-19, run by Radboud University Medical Center at 1 site in Netherlands.

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 11 inclusion and 11 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 28 Mar 2024. 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 Netherlands. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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: Recruitment rate dropped because of national COVID-19 vaccination campaign taking place parallel to this study.). 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?

Concentrations of SARS-CoV-2-Spike protein specific IgG antibodies in serum for the different intervention groups (time frame: at 28 days after vaccination). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Mar 2024.
