Efficacy of Leptin Replacement in Treatment of Genetic and Acquired Lipodystrophies
The study will be conducted as an open-label observational study to test the safety and potential efficacy of long term leptin replacement in patients with partial lipodystrophy.Following a screening evaluation, patients who qualify will be continued on leptin. eligible patients will be treated with metreleptin initially for a period of 12 months, during which they will be evaluated at yearly intervals. if the patient maintains improvements in his/her metabolic parameters while on metreleptin, the patient will be invited to continue taking the study medication as long as astra Zeneca is willing to continue providing drug. During the long term extension, metabolic parameters will be monitored every 12 months.
