About this study

Official title: Phase I Study Evaluating the Safety and Efficacy of the Protective Adjuvanted Inactivated Vaccine Developed Against SARS-CoV-2 in Healthy Participants, Administered as Two Injections Subcutaneously in Two Different Dosages.

This phase I study is designed as double-blinded, randomised, placebo controlled, three-armed study composed of two different dose arms of protective adjuvanted inactivated vaccine against SARS-CoV-2 in dose escalations (first low dose group, followed by high dose group) and placebo arm.

Read the detailed description

This phase I study is designed as double-blinded, randomised, placebo controlled, three-armed study composed of two different dose arms of protective adjuvanted inactivated vaccine against SARS-CoV-2 in dose escalations (first low dose group, followed by high dose group) and placebo arm. Each dose of vaccine will be defined as a cohort in itself, with vaccine administration to 20 participants and placebo administration to 5 participants. After completion of low-dose group, decision of switch to high-dose will be taken by the Independent Data Monitoring Committee and will continue accordingly.

In the study, 50 healthy participants of 18-45 years of age will be recruited.

All injections will be done subcutaneously.

Injections will be administered at 1 and 21 days.

The participants will be followed for 6 months and the study will be completed in 12 months.

What is being measured

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

  1. Acute adverse events (AEs)

    Frequency of acute adverse events in all dosage groups

    Measured: 24 hours

  2. Solicited local and systemic adverse events (AEs)

    Frequency of local and systemic AEs in all dosage groups

    Measured: 15 days

  3. Unsolicited local and systemic adverse events (AEs)

    Frequency of local and systemic AEs in all dosage groups

    Measured: 28 days

Secondary outcomes (2)
  1. Neutralizing antibody response

    Immunogenicity response by measuring neutralizing antibody titer (anti-spike and anti-RBD) developed against SARS-CoV-2 (by ELISA)

    Measured: Before first dose administration, on Day 21-28-35 and Month 3 and Month 6 after first dose administration.

  2. Cellular immune response

    Interferon-γ (IFN-γ) positive cell level (by ELISPOT)

    Measured: Before first dose administration, on Day 21-28-35 and Month 3 and Month 6 after first dose administration.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SARS-CoV-2 vaccine in people with Covid19, run by Osman ERGANIS, PhD, Prof at 1 site in Turkey (Türkiye).

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 12 inclusion and 18 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 18 Apr 2023. 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 Turkey (Türkiye). 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. Some participants in this study may receive a placebo. 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: Although cellular responses to virus were satisfactory, neutralizing titres against virus were lower then expected levels). 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?

Acute adverse events (AEs) (time frame: 24 hours). The study lists 3 primary outcomes in all. 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 18 Apr 2023.
