NCT01326533

Brief Summary

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.

You may qualify if:

  • Age \> or = 18, able to provide informed consent
