Pilot Study of the Navigator Continuous Glucose Monitor Phase 2, Phase 3 60 At-Home

Completed
Clinical Trial NCT00166673 was an interventional study for Diabetes Mellitus, Insulin-Dependent that is now completed. The study started on 1 August 2005, with plans to enroll 60 participants. Led by Jaeb Center for Health Research, the expected completion date was 1 August 2007. The latest data from ClinicalTrials.gov was last updated on 5 September 2016.
Brief Summary
This study is being done to find out how accurate the Navigator continuous glucose monitor is in children. It is also being done to see if use of the Navigator can improve blood sugar control and help prevent low blood sugar events. This study has three basic parts: Use of the Navigator at home for one week without being able to see the blood sugar readings; a Baseline visit or a 24-hour admission to a research unit ...Show More
Detailed Description
Approximately 60 children will be recruited from five centers in the United States to participate in this study. The information gained from this study will be used to plan a larger study in which half of the patients will use the Navigator and half will not. Children who participate in this study will not be eligible to take part in the larger study.

The Navigator provides a glucose reading every 60 seconds (or 144...

Eligibility Criteria

Eligible Ages
Child
Minimum Age
3 Years
Eligible Sexes
All
  • Clinical diagnosis of type 1 diabetes and using daily insulin therapy for at least one year The diagnosis of type 1 diabetes is based on the investigator's judgment; C peptide level and antibody determinations are not needed.
  • Age 3.0 years to less than 18.0 years
  • Subject has used a downloadable insulin pump or Lantus with MDI of a short-acting insulin (e.g. Humalog or Novolog) for at least 6 months
  • Parent/guardian and subject understand the study protocol and agree to comply with it
  • Subjects >9.0 years old and primary care giver (i.e., parent or guardian) comprehend written English
  • Subject has a home computer with email access
  • For females, subject not intending to become pregnant during the next 3 months
  • No expectation that subject will be moving out of the area of the clinical center during the next 3 months
  • Informed Consent Form signed by the parent/guardian and Child Assent Form signed by the subject

  • The presence of a significant medical disorder that in the judgment of the investigator will affect the wearing of the sensors or the completion of any aspect of the protocol.

  • The presence of any of the following diseases:

    • Asthma if treated with systemic or inhaled corticosteroids in the last 6 months
    • Cystic fibrosis
    • Other major illness that in the judgment of the investigator might interfere with the completion of the protocol (Adequately treated thyroid disease and celiac disease do not exclude subjects from enrollment)
  • Inpatient psychiatric treatment in the past 6 months for either the subject or the subject's primary care giver (i.e., parent or guardian).
