About this study

Official title: VOICES: Vaccine Observation to Include All Communities for Equitable Science

VOICES is a longitudinal, prospective, observational study that will enroll up to 10,000 subjects of diverse racial backgrounds being administered an emergency use authorized COVID-19 vaccine, for collection and analysis of stool and blood samples. It has recently been shown that the gut microbiome, the collection of microbes that line our GI tract, play a significant role in vaccine immune response and severe complications from COVID-19. The identification of biomarkers may aid in predicting response to vaccination and are critical towards improving vaccine-induced immunity. These real-world patient derived biomarkers could be used as interventional targets for the design of innovative adjuvant co-therapies that can boost an effective immune response to the vaccine, enhancing efficacy for a broader population, including those at most risk.

Subjects who meet the entry criteria will provide two samples each of blood, one prior to and one following vaccine administration. Follow-up questionnaires will be sent at 3, 6, 9, and 12 months to determine if participants have contracted COVID-19 or have experienced any adverse effects of the vaccine. Nasal swab samples will also be collected from participants that have contracted COVID-19. The samples will be analyzed to determine the impact of gut microbiome composition and function on the immune system and vaccine efficacy.

What is being measured

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

  1. Determine whether the microbiome composition can predict effectiveness of vaccine.

    Whole genome sequencing and metabolomics will be used to characterize the patient's microbiome, and whether there is any correlation with subjects who contract COVID-19 post-vaccination

    Measured: 6-12 months

Secondary outcomes (3)
  1. Identify correlations between microbiome composition and immune system response to the vaccine

    Immune cell profile and cytokine analysis will be performed on the blood samples to characterize the patient's immune phenotype, and determine how it correlates to microbiome composition

    Measured: 3-6 months

  2. Track coronavirus variants of any individuals infected

    Any subject who contracts COVID-19 after vaccination will provide a nasal swab, which will be subject to viral sequencing to determine whether vaccinated individuals are more susceptible to certain variants

    Measured: 6-12 months

  3. Build a library of samples and data for future research

    Samples will be stored and data saved in a HIPAA-compliant database. Samples will be linked to patient metadata

    Measured: 6-24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Vaccine Response Impaired and Vaccine Adverse Reaction, run by Persephone Biosciences at 1 site in United States.

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 2 inclusion and 3 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 5 Apr 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 United States. 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.

Are results available for this study?

The study was stopped early (reason given: No longer of interest to the company). 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?

Determine whether the microbiome composition can predict effectiveness of vaccine. (time frame: 6-12 months). 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 5 Apr 2024.
