About this study

Official title: Randomized, Comparative and Prospective Clinical Trial Evaluating Efficacy and Safety of a Dose of Seasonal Flu Vaccine Compared to Two Doses of Vaccine for Prevention of Influenza in Solid Organ Transplant Recipients

Randomized, multicenter, open label trial to compare safety and efficacy of two doses stationary flu vaccination vs one doses in Solid Organ Transplant Recipients.

Read the detailed description

The purposes of this study are:

  1. Evaluate the efficacy and safety of a double dose of seasonal flu vaccine compared to a single dose.
  2. Determine the specific cellular immune response produced after the first and second vaccine doses of seasonal flu vaccine by in vitro stimulation of specific memory cells (A and B flu viruses).
  3. Evaluate the humoral immune response produced after one dose vs two doses of seasonal flu vaccine by the measure of serum antibody levels.
  4. Evaluate clinical efficacy of stationary flu vaccine in solid organ transplant recipients.
  5. Evaluate a long term cellular and humoral response(1 year) of seasonal flu vaccine.
  6. Characterize the genetic expression profile of immune response after the flu vaccine in solid organ transplant recipients by means of a genetic sub-study.
  7. Characterize the flu vaccine effect (one dose and two doses) through the antibody anti-HLA(human leukocyte antigen), and its influence on the rejection rate in solid organ transplant recipients, by means of immunologic sub-study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Influenza vaccineBiological

    Patients will be randomized at 1:1 rate and open label fashion, according to centers, and time elapsed since transplant and type of organ transplanted to one of this two interventions :

    A arm (usual treatment): Influenza vaccine (split virion, inactivated) suspension for injection 0.5ml at the baseline.

    B arm (experimental branch): Influenza vaccine (split virion, inactivated) suspension for injection 0.5ml at the baseline and 5 weeks after the first dose.

    The follow-up of both arms will be at 5, 10 and 15 weeks and one year after the baseline.

What is being measured

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

  1. Seroconversion rates

    Difference in seroconversion rates in both treatment groups at 5, 10, 15 weeks, and 12 months after the first vaccine dose (percent of patients with 4 x increase in the pre-vaccination titers).

    Measured: At 5, 10, 15 weeks, and 12 months after the first vaccine dose

Secondary outcomes (6)
  1. Postvaccination antibody titers

    Geometric average postvaccination antibody titers and rate of increase between pre-and post-vaccination geometric mean, post-vaccination seroprotection rate (or percentage of individuals with a titer 1 / 40 as measured by RIH).

    Measured: At 5, 10, 15 weeks, and 12 months after the first vaccine dose.

  2. Safety.

    Occurrence of grade 3 or 4 toxicity, death, hospitalization, retransplantation, acute rejection and chronic rejection

    Measured: At 5, 10, 15 weeks, and 12 months after the first vaccine dose

  3. Efficacy

    Detection of clinical cases of influenza following immunization. Nasal swabs to confirm infection with influenza virus by RT-PCR (Reverse transcription polymerase chain reaction).

    Measured: At 5, 10, 15 weeks, and 12 months after the first vaccine dose

  4. Antibody anti-HLA

    Characterize the flu vaccine effect (one dose and two doses) through the antibody anti-HLA levels, ant its influence on the rejection rate in solid organ transplant recipients, by means of immunologic sub-study.

    Measured: At 5, 10, 15 weeks, and 12 months after the first vaccine dose

  5. Cellular response

    Determination of the T cells specific immune response measured by production of INFg, IL-2 and IL-4 in the cytoplasm of CD4+ and CD8 + (mononuclear cells) specific for influenza virus by direct immunofluorescence and flow cytometry analysis.

    Measured: At 5, 10, 15 weeks, and 12 months after the first vaccine dose

  6. Clinical complications

    Clinical severity (hospitalization, ICU admission, death, rejection). Time to clinical stability will be register.

    Measured: At 5, 10, 15 weeks, and 12 months after the first vaccine dose

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Influenza vaccine in people with Infection in Solid Organ Transplant Recipients, run by Fundación Pública Andaluza Progreso y Salud at 12 sites 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 5 inclusion and 5 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 1 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites 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 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?

Seroconversion rates (time frame: At 5, 10, 15 weeks, and 12 months after the first vaccine dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01761435, which also lists 2 linked publications.

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 1 May 2015.
