This study is conducted in the United States of America (USA). The aim of the study is to assess longitudinal variation of immune biomarkers in subjects at risk for development of type 1 diabetes (T1D).

Condition Intervention
Diabetes Mellitus, Type 1
Other: No treatment given

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: The Longitudinal Diabetes Biomarker Study: An Observational Study to Assess Longitudinal Variation of Immune Biomarkers in Subjects at Risk for Development of Type 1 Diabetes

Further study details as provided by Novo Nordisk A/S:

Primary Outcome Measures:
  • Fluctuation in islet autoantibodies titers [ Time Frame: One-two years dependent on sampling frequency ]

Secondary Outcome Measures:
  • Fluctuation in islet autoantibody isotypes [ Time Frame: One-two years dependent on sampling frequency ]
  • Fluctuation in T-cell specificity profiling (mainly for CD8 (cluster of differentiation 8) T-cells) [ Time Frame: One-two years dependent on sampling frequency ]

Biospecimen Retention:   Samples With DNA
Blood sampling for biomarkers. A portion of each sample collected will be tested for five different islet autoantibodies (presence and precise titers). The remaining portion of each sample will be coded and then assessed for autoantibody isotypes, phenotyping of peripheral blood mononuclear cells (PBMC), and profiling of cytokines, and pharmacogenetic markers.

Enrollment: 40
Study Start Date: May 2013
Study Completion Date: September 2015
Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
All participants Other: No treatment given
The participants will not receive any treatment.


Ages Eligible for Study:   4 Years to 40 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
Subjects who are at risk for developing T1D either by genetic testing or due to family history and identified with one or more islet autoantibodies).

Inclusion Criteria:

  • Subjects with general good health as judged by the investigator
  • Participant tested positive at above or equal to 99th percentile for one or more of three islet antibodies (GAD (glutamic acid decarboxylase), IA2 (islet antigen-2), IAA (insulin autoantibody))

Exclusion Criteria:

  • Any chronic disorder (diabetes at enrolment) or severe disease which, in the opinion of the investigator, might jeopardize subject's safety or compliance with the protocol
  • Female of child-bearing potential who is pregnant, breast-feeding, or intends to become pregnant
