TODAY Genetics Study

July 28, 2021 updated by: National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)

Studies to Treat Or Prevent Pediatric Type 2 Diabetes (STOPP-T2D) Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) Genetics Study

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

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.

Description

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.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Blood draw to be processed and analyzed to yield genetic data.
Time Frame: Blood is drawn at the single study visit.
Blood is sent to the DNA processing center identified by NIDDK for processing and shipment to the NIDDK Repository.
Blood is drawn at the single study visit.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2008

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
