Pre-diabetes in Subject With Impaired Fasting Glucose (IFG) and Impaired Glucose Tolerance (IGT) (NCT02969798)

Preservation of Beta Cell Function in Pre-diabetes in Subject With Impaired Fasting Glucose (IFG) and Impaired Glucose Tolerance (IGT)

🟢 Recruiting Observational / Diagnostic 💊 Investigational Drug / Biologic Sponsor: The University of Texas Health Science Center at San Antonio

🩺 Plain-English Summary (8th-Grade Level)

HYPOTHESIS: Impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) have distinct pathophysiologic etiologies. Therefore, therapeutic interventions designed to correct the specific underlying pathogenic abnormalities in IGT and IFG will be required to optimally prevent the progressive beta cell failure and development of overt type 2 diabetes.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (16 items) and avoid the listed exclusions (21 items).

Location: The University of Texas Health Science Center at San Antonio — San Antonio, Texas

Age range: 18 Years to 65 Years

Instant Checklist

Check every box below. If you can check all of them, you may meet the study's basic screening requirements (final eligibility is confirmed by the site team).

Usually NOT eligible if any of the following apply:

  • Exclusion Criteria:
  • Recent (i.e., within three (3) months prior to Screening) evidence or medical history of unstable concurrent disease such as: documented evidence or history of clinically significant hematological, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, immunological, or clinically significant neurological disease.
  • Subjects with a family history of diabetes in a first degree relative
  • BMI of less than 24 or greater than 40 kg/m2
  • Unstable body weight (change of greater than ±4lbs over the preceding 3 months
  • Subjects participating in an excessively heavy exercise program
  • Subject with a feeding/sleeping schedule different from a daytime feeding/night time sleeping schedule
  • Subjects taking medications known to alter glucose metabolism (with the exception of metformin and/or pioglitazone) or which effect brain neurosynaptic function are excluded.
  • Subjects with evidence of major organ system disease as determined by physical exam, history, and screening laboratory data
  • Pregnant subjects or subjects unwilling to use birth control during their study enrollment
  • Blood donation of approximately 1 pint (500 mL) within 8 weeks prior to Screening.
  • Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study
