Reducing Risk of Type 2 Diabetes: Hydroxychloroquine Use in Pre-Diabetes
Mechanisms of Action of Hydroxychloroquine in Reducing Risk of Type 2 Diabetes

The purpose of this study is to determine the short-term effects of the antimalarial medication, hydroxychloroquine (HCQ), compared with placebo using frequently sampled intravenous glucose tolerance testing (FSIGTT) methodology to study changes in insulin secretion and glucose tolerance in subjects at risk for developing Type 2 diabetes.

Diabetes is approaching epidemic proportions in the United States. Efforts to implement effective strategies for diabetes prevention have been limited by poor long term adherence to lifestyle modifications and potential side effects and costs of pharmacologic interventions. This study evaluates the mechanisms of action of a generic drug that may be a useful alternative to existing interventions to prevent the development of Type 2 diabetes mellitus.

  8. Inability to comply with visit schedule and protocol requirements
  9. Inability to manage and take medication as instructed
  10. Current or planned pregnancy in upcoming 12 months
  11. Inability or unwillingness to use reliable method of contraception (for women of childbearing years, men, or men's partners with childbearing potential), such as oral contraceptive pills, barrier method (diaphragm and condom with spermicide), intrauterine device, or depo-provera injections for 3 months prior to enrollment
  12. Anemia (HGB < 9)
  13. Any history of bariatric (weight loss) surgery
  14. Current use of the medication Glucophage (metformin)
  15. Weight changes of 6 pounds or more in the past 4 weeks
  16. Any other underlying or concomitant condition, which in the opinion of the principal investigator, could confound the results of the study or put the subject at undue risk
