About this study

Official title: A Phase III, Parallel Group, Prospective, Randomized, Double-blind, Active-controlled, Two-arm, Multi-center Study to Evaluate the Immunogenicity, Safety, and Tolerability of MVC-COV1901 Compared to AZD1222 in Adults of 18 Years and Above

The purpose of this study is to assess the immunogenicity and safety of MVC-COV1901 vaccine compared to AZD1222 in heathy adults.

Read the detailed description

The primary objective of the study is to measure the anti-SARS-CoV-2 neutralizing antibody titers in adult participants so as to demonstrate immunogenic superiority of MVC-COV1901 to the active control, AZD1222 vaccine, in terms of the GMT ratio of neutralizing antibodies at 14 days after the second dose of study intervention. This study also assesses the safety and tolerability of the study intervention and explores the immunogenicity in terms of anti-S IgG as well as the potential efficacy of MVC-COV1901 in preventing COVID-19.

What is being measured

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

  1. Immunogenicity of neutralizing antibody (GMT ratio)

    To demonstrate the immunogenic superiority of MVC-COV1901 to AZD1222 in terms of neutralizing antibody titers at 14 days after the second vaccination

    -GMT ratio

    Measured: Day 1 to Day 43

  2. Incidence of Adverse Event within 28 days post the second study intervention

    To evaluate the safety and tolerability of MVC-COV1901 compared to AZD1222 from Day 1 to 28 days after the second vaccination

    The number and percentage of participants with the occurrence of:

    • Solicited local AEs
    • Solicited systemic AEs
    • Unsolicited AEs
    • Medically attended AEs (MAAEs)
    • AESIs
    • VAED
    • SAEs

    Measured: Day 1 to Day 57

Secondary outcomes (4)
  1. Immunogenicity of neutralizing antibody (GMT)

    To evaluate the immunogenicity of MVC-COV1901 compared to AZD1222 in terms of neutralizing antibody titers from Day 29 to Day 209

    • GMT

    Measured: Day 29 to Day 209

  2. Immunogenicity of neutralizing antibody(SCR)

    To evaluate the immunogenicity of MVC-COV1901 compared to AZD1222 in terms of neutralizing antibody titers from Day 29 to Day 209

    • SCR

    Measured: Day 29 to Day 209

  3. Immunogenicity of neutralizing antibody(GMT ratio)

    To evaluate the immunogenicity of MVC-COV1901 compared to AZD1222 in terms of neutralizing antibody titers from Day 29 to Day 209

    • GMT ratio

    Measured: Day 29 to Day 209

  4. Incidence of Adverse Event throughout study conduct

    To evaluate the safety of MVC COV1901 compared to AZD1222 over the study period

    The number and percentage of participants with the occurrence of:

    • MAAEs
    • AESIs
    • VAED
    • SAEs

    Measured: Day 1 to 180 days after second vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing MVC-COV1901 and AZD1222 in people with Covid19 Vaccine, run by Medigen Vaccine Biologics Corp. at 2 sites in Paraguay.

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 8 inclusion and 17 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: finished, as of the sponsor's last update on 30 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Paraguay. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Immunogenicity of neutralizing antibody (GMT ratio) (time frame: Day 1 to Day 43). The study lists 2 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 30 Sep 2022; AzTrials last refreshed its copy on 7 Nov 2026.
