About this study

Official title: Randomized, Open-label, Adaptive, Controlled, Phase III Clinical Trial to Evaluate the Efficacy, Safety and Immunogenicity of Reimmunization With Third Dose of Homologous vs. Heterologous Vaccine Against COVID-19 in Patients Undergoing Solid Organ Transplantation: Liver, Heart, Kidney and Lung.

Patients undergoing solid organ transplantation randomly selected from those who have received two doses of Spikevax (Moderna) vaccine, provided that a minimum of 8 weeks have elapsed from the second dose to the time of the start of the trial. It is planned to include 386 patients.

Read the detailed description

The main objective of this trial is to evaluate the immunogenicity of reimmunization against SARS-CoV-2 in patients undergoing solid organ transplantation with heterologous revaccination, testing whether in patients who received two doses of Spikevax Moderna vaccine there is a significant increase at 28 days in their antibody titers against SARS-CoV-2 after receiving a dose of Janssen.

The secondary objectives of this trial are:

  1. To evaluate the efficacy of reimmunization against SARS-CoV-2 in subjects undergoing solid organ transplantation, in terms of incidence of infection and severity of COVID-19 after revaccination in the transplanted patient.
  2. To gain insight into the humoral and cellular immune response conferred by the sequential combination of both homologous and heterologous vaccination over one year, as well as its duration in subjects undergoing solid organ transplantation.
  3. To evaluate the safety of vaccines against SARS-CoV-2 in subjects undergoing solid organ transplantation.
  4. To determine the potential existence of differences in humoral (Anti S Ac) and cellular immune response depending on the immunosuppression regimen.
  5. To evaluate the occurrence of side effects, including rejection and anti-HLA and DSA antibodies after revaccination.

What is being measured

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

  1. Changes in the production of anti-S1-RBD IgG antibodies.

    Positivity for comparison before and after revaccination and according to homologous or heterologous vaccination will be quantified in the laboratory method units.

    Measured: 28 days

Secondary outcomes (4)
  1. Change in the presence of activated T cells specific for SARS-CoV-2 (Sprotein).

    T-cell response to SARS-CoV-2 will be analyzed by flow cytometry.

    Measured: 1 year

  2. Changes in the phenotype of effector/memory/virgin B and T cell populations and subtypes of Th and NK cell populations.

    T-cell response to SARS-CoV-2 will be analyzed by flow cytometry.

    Measured: 1 year

  3. Incidence of symptomatic/asymptomatic COVID infection after revaccination.

    Confirmed COVID-19 is defined as the presence of at least one of the following symptoms: fever, new onset or increased cough, new onset or increased shortness of breath, chills, new onset or increased muscle pain, loss of taste or smell, sore throat, diarrhea or vomiting, combined with a respiratory specimen, obtained during the symptomatic period, positive for SARS-CoV-2 by nucleic acid amplification (PCR)-based testing or antigen testing.

    Measured: 1 year

  4. Number of patients with hospital admissions and/or visits to the emergency department for severe symptoms related to COVID-19 infection.

    Confirmed COVID-19 is defined as the presence of at least one of the following symptoms: fever, new onset or increased cough, new onset or increased shortness of breath, chills, new onset or increased muscle pain, loss of taste or smell, sore throat, diarrhea or vomiting, combined with a respiratory specimen, obtained during the symptomatic period, positive for SARS-CoV-2 by nucleic acid amplification (PCR)-based testing or antigen testing.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Janssen vaccine and Spikevax (Moderna) vaccine in people with Covid19, run by Instituto de Investigación Marqués de Valdecilla at 1 site in Spain.

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 4 inclusion and 9 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: withdrawn, as of the sponsor's last update on 2 Mar 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 Spain. 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 was withdrawn before enrolling participants, so there are no results.

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?

Changes in the production of anti-S1-RBD IgG antibodies. (time frame: 28 days). 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 2 Mar 2023.
