- Generalized lipodystrophy can cause high blood fat levels and resistance to insulin. This can lead to health problems including diabetes. Researchers have found that the drug metreleptin improves health in people with this disease.
- To test the safety and effectiveness of metreleptin.
- People ages 6 months and older with generalized lipodystrophy who:
- have received metreleptin through NIH studies AND
- cannot get it through approved or compassionate use mechanisms in their home country.
- Participants will come to NIH approximately every 6 months during year one, then every 1 2 years. Financial assistance may be available for travel within the U.S.
- At visits, participants will get a supply of metreleptin to take home for daily injections. They will have:
- plastic catheter placed in an arm vein.
- blood tests, urine collection, and physical exam.
- oral glucose tolerance test, drinking a sweet liquid.
- ultrasound of the heart, liver, uterus, and ovaries. A gel and a probe are placed on the skin and pictures are taken of the organs.
- echocardiogram, which takes pictures of the heart with sound waves.
- Resting Metabolic Rate taken. A plastic hood is worn over the head while the oxygen they breathe is measured.
- Participants will have up to 3 DEXA scan x-rays per year.
- Participants may have:
- annual bone x-rays.
- liver biopsies every few years. A needle will be inserted into the liver to obtain a small piece. Participants will sign a separate consent for this.
- Participants must be seen regularly by their local doctors and have blood tests at least every 3 6 months at home.

|Lipodystrophy Diabetes Hyperlipidemia||Drug: Metreleptin||Phase 3|
Leptin is an adipocyte-derived hormone that can be thought of as a signal from adipose tissue to the rest of the body conveying information about long-term nutritional status. Patients with the very rare condition of generalized lipodystrophy have leptin deficiency secondary to lack of adipose tissue. The combination of leptin deficiency and ectopic lipid deposition in patients with lipodystrophy leads to metabolic complications including severe insulin resistance and diabetes, hypertriglyceridemia, nonalcoholic steatohepatitis, and polycystic ovarian syndrome. Between 2000 and 2014, the NIDDK IRP conducted an open-label clinical trial of the recombinant human leptin analog, metreleptin, in patients with generalized and partial forms of lipodystrophy. This study showed that metreleptin ameliorates metabolic and endocrine abnormalities in lipodystrophy, including reducing food intake, improving insulin resistance and diabetes, reducing ectopic lipid, and normalizing reproduction. Based on these data, metreleptin was approved by the FDA in February, 2014, for patients with generalized, but not partial, lipodystrophy.
Currently, metreleptin is not available as an approved drug outside the US and Japan, and it is available on a compassionate use basis only in a few additional countries. The purpose of this study is twofold:
- To provide access to metreleptin to patients with generalized lipodystrophy, including those who have previously received metreleptin through NIH studies (protocols 02-DK-0022 and 13-DK- 0057) AND/OR who cannot obtain metreleptin through approved or compassionate use mechanisms in their home country
- To continue to collect data on the long-term efficacy of metreleptin in ameliorating the metabolic complications of generalized lipodystrophy.
Metreleptin will be given at doses of less than or equal to 0.24 mg/kg/day, adjusted based on body weight and metabolic control. Patients will be seen approximately once per year at NIH for evaluation, and potentially less frequently for those who are medically stable and have difficulty traveling to the US. Laboratory evaluation will be obtained more frequently by the patient s home providers as clinically indicated. The primary outcomes of the study are improvements in serum triglycerides and hemoglobin A1c levels. Secondary outcomes include measures of steatohepatitis and ectopic lipid, body composition, bone mineral density and bone mineral metabolism, and pituitary and reproductive function.
Metreleptin is supplied by Aegerion Pharmaceuticals. Neither the NIH nor Aegerion Pharmaceuticals can guarantee that leptin will be available for these patients indefinitely and/or after the study ends.
