Trial summary

Cystic fibrosis (CF) is the most common lethal, inherited disorder among Caucasians. Choline is an essential vitamin and as a methyl donor is critically needed to support the normal metabolism. Our previous studies have demonstrated that children with CF have depleted levels of choline. Read more about this study

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 5 to 17 years
  • All sexes
  • Healthy volunteers accepted
  • Child

Who may be able to join

  • children aged 5-17 yr with proven CF and known genotype
  • with stable pulmonary disease, are outpatients with no hospitalizations or changes to antibiotic regiment during the previous 1 month and not receiving any parenteral nutrition
  • are non-smokers without asthma, may be taking routine fat soluble vitamins but must not be taking any supplemental fish oil, docosahexanoic acid (DHA) or choline containing compounds, experimental drugs or any aerosol or oral interventions designed to deliver or increase glutathione or receiving oral or parenteral corticosteroidal medications. E.g prednisone.

Who cannot join

  • are not 5-17 years of age, do not have CF or have the medical condition trimethylaminuria.
  • have CF, but have allergies to any of the ingredients in the choline supplements; are hospitalized; have asthma or are smokers; are taking oral or parenteral corticosteroidal medications or any intravenous nutritional support; have kidney or liver disease; or have a baseline FEV 1 of less than 50% predicted value (which at our clinic means they are likely hospitalized or about to be admitted to hospital).

About this study

Cystic fibrosis (CF) is the most common lethal, inherited disorder among Caucasians. Choline is an essential vitamin and as a methyl donor is critically needed to support the normal metabolism. Our previous studies have demonstrated that children with CF have depleted levels of choline. The purpose of this study is to supply a choline supplement to children with CF to see if their nutrition and methyl status can be improved.

Read the detailed description

This will be a prospective, repeated measures study involving 34 children with CF who will take a supplement of water soluble choline bitartrate, 2 gm/day with meals for 6 months. The baseline (day 0) results for each child will serve as his/her own control, and assessments will be made at 3 months and 6 months choline supplementation and again 3 months after stopping choline.

The supplement will be provided as capsules containing 250 mg choline bitartrate. 4 capsules will be taken with or immediately before each of two meals per day: breakfast and dinnertime meals, providing 1 gm of supplemental choline each day.

The children will be enrolled by description of the project to the child and their parent(s) at a CF clinic appointment. Body weight, height and blood pressure will be measured and routine blood work including liver enzymes, hematology, serum zinc, selenium and vitamins A and E will be completed as part of the clinic appointment. The hematology and clinical chemistry will be done by the Hematopathology and Clinical Chemistry labs at the B.C.'s Children's Hospital. CF genotype, gender, birth date, hematology, clinical chemistry, anthropometry, nutritional measures, pulmonary function test results, chest X-Ray and/or CT scans, pancreatic function test results (fecal elastase, chymotrypsin or secretin-CCK), medications and supplements (including enzymes, vitamins, minerals, nutrition supplements \& Natural Health Products) and where available, liver ultrasound and biopsy reports will be collected from chart data. Information in the subject's medical charts relating to antibiotic therapy, duration of illnesses, hospitalization and diagnosis will be reviewed to ensure the inclusion/exclusion criteria are met.

Assessment of pulmonary function by computer assisted spirometry which includes the measures of forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and forced mid-expiratory flow (FEF 25-75) is completed for all children as part of each regularly scheduled clinic visit and the results collected for this study.

What participants receive

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

  • Vitamin: Choline Bitartrate (2-hydroxyethyl) trimethylammonium salt 1:1Dietary supplement

    This is a prospective, repeated measures study involving children with Cystic Fibrosis. Children will be assessed (1) before starting the choline supplement, (2) after taking the supplement for 6 months and after the supplement has been discontinued for 3 months.

Questions about this trial

What is this clinical trial studying?

A study testing Vitamin: Choline Bitartrate (2-hydroxyethyl) trimethylammonium salt 1:1 in people with Cystic Fibrosis, run by University of British Columbia 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 3 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: finished, as of the sponsor's last update on 18 Feb 2010. 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.

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?

plasma choline, SAM, SAM/SAH ratio, homocysteine, GSH and the GSH/GSSG (time frame: 9 months). 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 18 Feb 2010.
