Trial summary

Measles is a vaccine-preventable disease, which can be life-threatening in immunosuppressed children. Currently, measles vaccine is not recommended in pediatric orthotopic liver transplant recipients, because it is a live-attenuated vaccine. Read more about this study

About this study

Official title: Induction and Maintenance of Immunity Against Measles in Pediatric Orthotopic Liver Transplantation Recipients: a Prospective Nationwide Study in Switzerland

Measles is a vaccine-preventable disease, which can be life-threatening in immunosuppressed children. Currently, measles vaccine is not recommended in pediatric orthotopic liver transplant recipients, because it is a live-attenuated vaccine.

We want to assess the influence of immunosuppression on immunity against measles in previously vaccinated children and to evaluate the induction of B cell and T cell response against measles elicited by vaccination in children at least 12 months after transplantation.

Read the detailed description

Eligible children in Group 2 will receive a standard dose (0.5 ml) of MMR vaccine during the first medical visit (V1). The lot number and the expiration date will both be recorded on the patient's case report form (CRF). A serological evaluation 4-8 weeks after MMR will identify children requiring an additional dose given 1-2 months apart, as currently recommended for subjects 1 year-old or with limited immune competence (i.e. HIV-infected children). Serological evaluation 4-8 weeks after the second dose or at the one-year follow-up will identify eventual non-responder requiring a third dose. Three will be the maximal number of administrated dose according to this protocol. The persistence of measles-specific antibodies will be assessed yearly, when patients come for their routine visit to the transplant center.

Children who do not need MMR immunization because of protective levels will be monitored yearly for maintenance of antibody levels during routine yearly visits/ blood samplings and will not have further intervention.

    Unprotected children will be vaccinated with two MMR vaccines

Receives: Biological: MMR vaccination

What is being measured

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

  1. serologic response to MMR vaccine in seronegative transplant recipients

    Pediatric transplant recipients will be vaccinated with MMR vaccine (previously seronegative) and their seroresponse will be measured 2 months later

    Measured: 2 months after vaccination

Secondary outcomes (1)
  1. Persistance of seroresponse to MMR vaccine

    Seroresponse to MMR vaccine will be followed over time in pediatric transplant recipients

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing MMR vaccination in people with Measles, run by Klara M. Pósfay Barbe at 1 site in Switzerland.

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 7 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: status not confirmed, as of the sponsor's last update on 18 Sep 2020. 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 Switzerland. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

serologic response to MMR vaccine in seronegative transplant recipients (time frame: 2 months after vaccination). 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 NCT01770119, 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 18 Sep 2020.
