Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 12 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: 1. Any adult, or young person over 12 years old, with a functioning transplant who has received at least 3 vaccines, will be eligible to participate. 2. People with rare autoimmune diseases, many of whom are on immunosuppressants, have validated disease diagnoses, and those treated with Rituximab who are most at risk of lack of seroconversion following COVID-19 vaccination. 3. People ≥18 years of age with a haematological malignancy who have received at least 3 vaccines will be eligible.

Who may be able to join

  • Adults and young people over 12 years of age, and are classified as being part of one of the following patient groups:
  • A solid organ transplant recipient (n=12,000)
  • Patients with a rare autoimmune disease (n=12,000)
  • Patients with lymphoid malignancies (n=12,000) -

About this study

Official title: Mass Evaluation of Lateral Flow Immunoassays for the Detection of SARS-CoV-2 Antibody Responses in Immunosuppressed People (The MELODY Study)

DESIGN Observational epidemiological study

AIMS - To determine:

  1. The proportion of immunosuppressed people who have detectable SARS-CoV-2 antibodies following a primary vaccine course (3 doses), and the demographic, disease, and treatment characteristics that influence antibody status.
  2. If the detection of antibodies inversely correlates with subsequent risk of severe acute respiratory syndrome coronavirus-2 infection and/or severity of disease in immunosuppressed people.
Read the detailed description

The aim of this proposal is to assess at a population level; 1) the proportion of immunosuppressed people who have detectable SARS-CoV-2 antibodies following a primary vaccine course (3 doses), and the sociodemographic, disease, and treatment characteristics that influence antibody status; 2) if the detection of antibodies inversely correlates with subsequent risk of SARS-CoV2 infection and/or severity of disease in immunosuppressed individuals.

The investigators aim to target patient groups least likely to mount an immune response to vaccination; a) solid organ transplant recipients; b) patients with a rare autoimmune disease c) patients with haematological malignancies, specifically lymphoid malignancies. The investigators will use comprehensive registries to identify and recruit patients from these groups, and utilise the existing linkages these registries already have to obtain COVID-19 outcome information.

The investigators hypothesise that a sizeable proportion of immunosuppressed people will have no detectable SARS-CoV-2 antibodies following a three vaccine doses, and that this cohort is particularly susceptible to SARS-CoV-2 infection and death.

What participants receive

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

  • self-administered lateral flow assaysDiagnostic test

    The lateral flow device to be used is the Fortress COVID-19 Total Antibody Device for the detection of IgM and IgG SARS-CoV-2 against the spike protein. The device has been evaluated for use in detecting anti-S in transplant patients and found to have a sensitivity of 92% and specificity of 95%.

What is being measured

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

  1. The Proportion of Participants With and Without Antibodies to SARS-CoV-2

    1. The proportion of with and without antibodies to SARS-CoV-2 at 21 - 90 days post three vaccine doses will be presented.

    Measured: 21 - 90 days post 3rd vaccine

  2. The Proportion of Participants With and Without Antibodies to SARS-CoV-2

    1. The proportion of participants with and without antibodies to SARS-CoV-2 at 21 - 90 days post four vaccine doses will be presented.

    Measured: 21 - 90 days post 4th vaccine

  3. The Incidence of Participants Having at Least One RT-qPCR Proven Infection in the 6-month Follow-up Period After 3rd or 4th Vaccine

    The incidence of participants having at least one RT-qPCR proven infection in the 6-month follow-up will be presented for those with and without antibodies to SARS-CoV-2 after 3rd or 4th vaccine.

    Measured: 6-month follow-up period from registration. Reporting of this is delayed following difficulties with collection of data from national bodies.

  4. The Incidence of Participants Hospitalised Due to COVID-19 and Deaths Due to COVID-19

    The incidence of participants hospitalised due to COVID-19 and deaths due to COVID-19 by 6 months will be presented for those with and without antibodies to SARS-CoV-2 following 3rd or 4th vaccine

    Measured: 6-month follow-up period from registration. Reporting of this is delayed following difficulties with collection of data from national bodies.

  5. Rates of Those With and Without Antibodies to SARS-CoV-2 After 3rd or 4th Vaccine

    Rates of those with and without antibodies to SARS-CoV-2 after 3rd or 4th vaccine will be presented for different clinical characteristics and sociodemographic factors.

    Measured: Antibodies at 21 - 90 days after 3rd or 4th vaccine

Questions about this trial

What is this clinical trial studying?

An observational study of Solid Organ Transplant Recipients and Autoimmune Diseases, run by Imperial College London at 4 sites in United Kingdom.

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 1 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 9 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United Kingdom. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Dec 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

The Proportion of Participants With and Without Antibodies to SARS-CoV-2 (time frame: 21 - 90 days post 3rd vaccine). The study lists 5 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 9 Dec 2024.
