Official Title  ICMJE Open Label Single Center Pilot Study to Study Teh Effects of Metreleptin Administration in Patients With Type 1 Diabetes Mellitus ( T1DM ).
Brief Summary This study will add leptin therapy to the current insulin therapy of Type 1 Diabetics with the aim of lowering the total insulin requirements and suppressing the steep fluctuations typically associated with Type 1 Diabetes.
Detailed Description The adipocyte hormone, leptin, has been shown to restore the health and glucoregulation of near-death, insulin deficient diabetic rodents. This makes leptin the only hormone, since the discovery of insulin in 1922, with this capability. Leptin normalizes the hyperglucagonemia of diabetes and reduces lipogenesis and cholesterologenenesis. Treatment of diabetic rodents with a combination of leptin and insulin, leads to a stable pattern of glucose control with reduced insulin requirements, as opposed to the high glucose variability that characterizes the treatment of type 1 diabetes with supraphysiologic doses of insulin alone. As such, we will initiate a pilot clinical trial to test combination leptin and insulin therapy in type 1 diabetes. Fifteen leptin sensitive patients (body mass index <27 kg/m²) with uncontrolled diabetes (HbA1c 7.0 to 10.0 %) will be treated with slightly supraphysiologic doses of recombinant human leptin (Amylin Pharmaceuticals). Subjects will be compared to themselves before and after treatment with leptin. Endpoint variables include HbA1c, change in daily insulin dose, mean and standard deviation of blood glucose from inpatient glucose monitoring and glucose meter download. We will also assess effects of leptin therapy on energy intake as assessed by 3-day food record and body weight and fat by DEXA. Intramyocellular and intrahepatic lipid concentration by 1H-MRS will be assessed before and after 3 months of metreleptin therapy. A satiety analysis will be employed. In addition, plasma hormones and inflammatory biomarkers will be assayed during the course of this study.

Eligibility Criteria  ICMJE

Inclusion Criteria:

All of the following criteria are to be fulfilled for inclusion of an individual in the study. An eligible individual:

  1. Is male or female and is 18 to 50 years of age
  2. Has been diagnosed with T1DM for at least 1 year. Diagnosis of T1DM will be based on clinical criteria including: insulin-dependence within 6 months of the onset, history of prior episode of ketoacidosis, previous documentation of positive serum islet cell autoantibodies or low or undetectable serum C-peptide levels.
  3. Has an HbA1c 7.0 to 10.0 %, inclusive
  4. Currently on insulin pump or on a combination of basal (long-acting insulin preparation) and pre-prandial (short-acting insulin preparation) insulin therapy
  5. Is male, or if female of childbearing potential, is non-lactating, and has a negative pregnancy test (human chorionic gonadotropin, beta subunit [βhCG]) result at screening (Visit 1) and Visit 2 regardless of menopausal status (If female and of childbearing potential [including peri menopausal women who have had a menstrual period within one year], must practice and be willing to continue to practice appropriate birth control [defined as a method which results in a low failure rate, i.e., less than 1% per year, when used consistently and correctly, such as implants, injectables, oral contraceptives, some intrauterine contraceptive devices, sexual abstinence, tubal ligation, or a vasectomized partner] during the entire duration of the study.)

    • Clinically significant malignancies within 5 years of screening (Visit 1)
