Summary

This trial is testing whether metreleptin, a medication used to treat patients with leptin deficiency, will improve glycemia control in patients with genetic defects of the insulin receptor. The primary endpoint is hemoglobin A1c and the trial will enroll 20 patients at the NIH Clinical Center.

Who is the study for?
This trial is for males and females over the age of 5 with severe insulin resistance due to insulin receptor mutations. Participants must have diabetes as defined by ADA criteria, with fasting insulin >30 micro U/ml or glucose levels indicating diabetes. Pregnant women, those not using birth control, or with certain infections like HIV are excluded.
What is being tested?
The study tests if metreleptin therapy (0.2 mg/kg/day) can improve blood sugar control in patients with genetic defects in the insulin receptor over a year. It's an open-label study at NIH Clinical Center focusing on changes in Hemoglobin A1c and other blood sugar markers.
What are the potential side effects?
Potential side effects of metreleptin may include allergic reactions (especially in those sensitive to E. Coli proteins), weight loss, headaches, abdominal pain, and low blood sugar events.
