About this study
Official title: Nasal Potential Difference Testing: Evaluation of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) Function in Children With Primary Sclerosing Cholangitis (PSC)
The investigators hypothesize that PSC in children is associated with mutations and functional changes of the cystic fibrosis (CF) gene.
Read the detailed description
The purpose of this protocol is to perform Nasal Transepithelial Potential Difference (NTPD) testing to assess the function of the cystic fibrosis gene product, a chloride channel referred to as CFTR, in patients diagnosed with PSC and/or inflammatory bowel disease in childhood and currently 12 years of age and greater.
Dr. Freedman's laboratory has shown that there is an increased prevalence of CFTR abnormalities in adults with PSC as demonstrated by genotype and phenotype analysis. We hypothesize that abnormalities in CFTR based on exhaustive genotype and phenotype assessments are associated with the presence of PSC in children. We would like to enroll patients with inflammatory bowel disease and no PSC to use as a "control group".
Subjects with PSC and/or inflammatory bowel disease diagnosed in childhood, currently aged 12 years and above, will be enrolled in study protocols at Children's Hospital in Boston, which will have received their local IRB approval. The only role for BIDMC will be to perform NTPD testing on these subjects. No other assessment or testing will be performed at our site. We will not be involved in any other aspect of care for these subjects.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Who may be eligible to take part?
The sponsor lists 4 inclusion and 0 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 13 Dec 2017. 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 United States. 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?

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?
CFTR DNA analysis. 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 13 Dec 2017.
