The TODAY study group has prepared a protocol with the primary objective of collecting blood and phenotypic information to be used to explore relationships between candidate genes and type 2 diabetes (T2D), as well as obesity, insulin resistance, and cardiovascular complications of insulin resistance. Participation in the genetics study includes a blood draw for analysis of diabetes type and DNA extraction, as well as collection of basic family and medical history. Appropriate informed consent and assent are obtained from all participants to extract DNA and send blood, genetic material, and medical history to the Central Repository of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH). The data are kept indefinitely by the Central Repository. The NIDDK will issue requests for proposals (RFP) throughout the scientific community for research that may help in the development of new diagnostic tests, new treatments, and new ways to prevent diabetes and other related comorbidities.

Type 2 Diabetes

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Cross-Sectional
Official Title: Studies to Treat Or Prevent Pediatric Type 2 Diabetes (STOPP-T2D) Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) Genetics Study

Further study details as provided by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK):

Primary Outcome Measures:
  • Blood draw to be processed and analyzed to yield genetic data. [ Time Frame: Blood is drawn at the single study visit. ] [ Designated as safety issue: No ]
    Blood is sent to the DNA processing center identified by NIDDK for processing and shipment to the NIDDK Repository.

Secondary Outcome Measures:
  • Phenotype data. [ Time Frame: Collected at single study visit. ] [ Designated as safety issue: No ]
    Demographic, medical history, and other data about participant and family, by self-report.

  • Laboratory values. [ Time Frame: Single study visit. ] [ Designated as safety issue: No ]
    Serum glucose, C-peptide, and pancreatic autoimmunity antibodies determined by study central laboratory.

Biospecimen Retention:   Samples With DNA

Collect 27 mL of blood to send (1) for extraction of DNA to the NIDDK Central Repository and (2) for measurement of glucose, C-peptide, and autoantibody analysis to a central blood laboratory.

Estimated Enrollment: 2500
Study Start Date: August 2008
Estimated Study Completion Date: February 2015
Estimated Primary Completion Date: February 2015 (Final data collection date for primary outcome measure)

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

Recruitment is conducted within a 'catchment' area that includes (a) the patient pools of the 15 TODAY clinical centers and (b) collaborating clinics and physicians who either refer subjects to a TODAY site or obtain IRB approval to conduct the protocol at their own locale.


Inclusion Criteria:

  • Diabetes by ADA criteria (laboratory determinations of fasting glucose ≥ 126 mg/dL, random glucose ≥ 200 mg/dL, or two-hour oral glucose tolerance test (OGTT) glucose ≥ 200 mg/dL) documented and confirmed in medical record or a laboratory determination of HbA1c ≥ 7%. For asymptomatic patients diagnosed with diabetes with a normal fasting glucose but an elevated two-hour glucose during an OGTT, the HbA1c must be ≥ 6%.
  • BMI ≥ 85th percentile documented at time of diagnosis or at screening.
  • Age < 18 at time of diagnosis.
  • Signed informed consent and assent forms as appropriate.

Exclusion Criteria:

  • Genetic syndrome or disorder known to affect glucose tolerance other than diabetes.
  • Patient on medication known to affect glucose tolerance, insulin sensitivity or secretion within 60 days of the time of diagnosis. If diagnosis is confirmed after the patient has been off the medication for 60 days, the patient may be included. Exclusionary medications include but are not limited to

    1. inhaled steroids at dose above 1000 mcg daily fluticasone equivalent,
    2. oral glucocorticoids,
    3. antirejection or chemotherapy agents (e.g., tacrolimus, L-asparaginase),
    4. atypical antipsychotics.
