About this study

Official title: COVID-19 Antibody Responses in Cystic Fibrosis: CAR-CF

Coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres in Europe. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments.

Associations will be examined between socio-demographic and clinical variables and serologic testing. The effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points will be examined to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time will be performed.

Read the detailed description

This is a prospective, longitudinal cohort study in people with Cystic Fibrosis (pwCF) that involves repeated serial sampling of participants. This study design was chosen to provide comprehensive information on SARS-CoV-2 seroprevalence changes over time and the subsequent clinical impact on pwCF. The study will be conducted at participating CF centres over a 3-year period. Study participants will include paediatric and adult pwCF. Participating investigators can enrol all eligible pwCF over a 12-month period. Participants are then followed up for 24 months. Participants will donate blood samples at their routine clinic visits. Blood samples will be collected at Day 0 (baseline), at Months 6, 12, 18 and 24 (to coincide with routine clinical reviews). Additional blood samples will be taken opportunistically every time the participant visits the clinic for blood draws. These blood samples could be related to, routine care, annual review visits, pulmonary exacerbations (PEx), CF complications or when initiating new treatments (e.g. CFTR modulators).

Serum from blood samples will be shipped to a central laboratory (Queen's University Belfast) for standardized measurement of SARS-CoV-2 antibodies.

Alongside the blood samples the investigators will also collect clinical data from the patient's health records and will input this data into the case report form (CRF). Clinical data will be collected in conjunction with routine care visits, according to local clinical practice. Investigators will collect data elements from information routinely recorded in the patients' medical records. Data will be collected at baseline, month 6, 12, 18 and 24 as per the study schedule, and at additional blood sampling timepoints as previously explained above. Data collection will include routine data available from CF clinic follow-ups including background demographic information, CF medical history, medications, exacerbation information, sputum microbiology and clinical and lung function parameters. Information on SARS-CoV-2 infection history and vaccine receipt will also be collected.

The maximum follow-up duration of participation in the study for each patient will be 24 months. This study duration (24-month follow-up) is justified as it provides sufficient time to observe changes in antibody prevalence over the course of the COVID-19 pandemic as well as sufficient time to determine long term clinical outcomes for pwCF who are SARS-CoV-2 seropositive. Furthermore, we anticipate the 2-year study follow-up period will provide sufficient time to observe the impact of vaccination on antibody levels given that a number of vaccines are now commercially available.

The investigators will compare the level of antibody responses between natural COVID-19 infection and vaccination in pwCF and how this varies over time. This will be achieved by analyzing seroprevalence and antibody levels according to natural infection and vaccination status and according to time of sample post infection or post vaccination, if known.

What is being measured

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

  1. SARS-COV-2 seroprevalence

    Proportion of pwCF with at least 1 seropositive result over the study period and the difference in this proportion by age, geographical area and over time.

    Measured: 3-year period (comprising a 1-year enrollment period and a 2-year follow-up)

  2. Association of SARS-CoV-2 seropositivity, clinical symptoms and clinical outcomes in pwCF

    Incidence of symptomatic COVID-19 over the study period and severity; proportion of seropositive pwCF with subsequent CF exacerbation compared to pwCF who are seronegative; death rate in pwCF with at least one seropositive result compared to pwCF who are seronegative.

    Measured: 3-year period (comprising a 1-year enrollment period and a 2-year follow-up)

  3. Longitudinal comparison of the detection of anti-SARS-CoV-2 antibodies in pwCF following natural infection and SARS-CoV-2 vaccination

    Measuring detectable antibody levels for each study participant at baseline and at each study time point including 6,12, 18 and 24 months post enrollment with additional samples if participant has blood drawn for other clinical care reason.

    Measured: 3-year period (comprising a 1-year enrollment period and a 2-year follow-up)

Questions about this trial

What is this clinical trial studying?

An observational study of Cystic Fibrosis and COVID-19, run by Children's Health Ireland at 2 sites in Ireland.

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 1 inclusion and 2 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 17 Jan 2024. 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 Ireland. 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?

Results are not available in the source record.

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?

SARS-COV-2 seroprevalence (time frame: 3-year period (comprising a 1-year enrollment period and a 2-year follow-up)). The study lists 3 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 17 Jan 2024.
