About this study
Official title: A Pilot Study of 18FDG-PET Imaging to Detect Changes in Airways Inflammation in Cystic Fibrosis Patients After Treatment for a Pulmonary Exacerbation
The purpose of this study is to determine if 18Fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) imaging can detect changes in airways inflammation in Cystic Fibrosis (CF) patients after treatment for a pulmonary exacerbation.
Read the detailed description
Neutrophils play a key role in the pathogenesis of CF lung disease. We know that neutrophilic inflammation is related to a decline in pulmonary function. Therefore, early anti-inflammatory intervention is an opportunity to slow this irreversible pulmonary destruction. However, the development of sensitive, non-invasive diagnostic tools of airways inflammation is essential to the study and implementation of anti-inflammatory therapies. Our current armentarium of measures of airways inflammation is limited. BAL is invasive and not clinically acceptable as a tool for the serial measurement of inflammation. Sputum samples are highly variable and not reliable.
18FDG-PET is a promising tool because it is non invasive, has been shown to quantify the amount and location of neutrophilic inflammation and has the potential to be used to track inflammation over time. Therefore, the goal of this research study is to evaluate the ability of 18FDG -PET imaging to detect changes in airways inflammation in CF patients in response to conventional treatment for a pulmonary exacerbation

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing 18-FDG in people with Cystic Fibrosis, run by The Hospital for Sick Children at 1 site in Canada.
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 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: finished, as of the sponsor's last update on 5 Oct 2018. 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 Canada. 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?
Change in airways inflammation detected by 18FDG -PET from baseline (time frame: Measured at end of treatment (day 14)). 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 5 Oct 2018.
