Brief Summary

The purpose of this study is to determine whether administration of an investigational medication called leptin (r-metHuLeptin) in replacement doses can improve bone health, reproductive function, hormone levels, immune function, and overall sense of well-being in women with hypothalamic (exercise-induced) amenorrhea (HA) who are being treated with oral contraceptive pills (OCPs), compared to placebo. Women with hypothalamic amenorrhea have low leptin levels. This study is based on the hypothesis that the relative leptin deficiency in women with hypothalamic (exercise-induced) amenorrhea may be the reason for the lack of menstrual cycles, hormone abnormalities, and bone loss associated with this condition.

Detailed Description

Leptin is a hormone secreted by fat cells under normal conditions and acts in the brain to regulate energy usage and hormone levels. Women with HA who do not have regular periods have low leptin levels and may also have other hormone abnormalities as well as loss of bone density (osteopenia or osteoporosis). This study will evaluate how leptin (a fat cell hormone that normally circulates in the blood) affects bone density, menstrual periods, hormone levels, bone metabolism (how bone forms and turns over), immune function (how well the body can fight infection), metabolic rate (how many calories are used at rest), and overall sense of well-being and appetite in women with HA (i.e. no regular menstrual periods due to low levels of pituitary hormones that regulate estrogen production from the ovary). It will also investigate whether leptin replacement can be used as an adjunct to the current standard of care for HA patients, i.e. OCPs.

Part A is a Randomized, placebo-controlled 36-week study. Part B is an Optional open-label 52-week study. There will also be an optional Reward Sub-study, including healthy controls, designed to investigate leptin's relation to reward processing by collecting participants' brain and behavioral responses to images (e.g., pictures of food vs. non-food). Brain responses will be collected and will also be assessed via functional Magnetic Resonance Imaging (fMRI).

Comparison: Part A = leptin-treated group to placebo-treated group and Part B optional sub study = leptin-treated group to health controls

• Conditions that are contraindicated for oral contraceptive use:
• Thrombophlebitis or thromboembolic disorders
• A past history of deep vein thrombophlebitis or thromboembolic disorders
• Cerebral vascular or coronary artery disease
• Known or suspected carcinoma of the breast
• Carcinoma of the endometrium or other known or suspected estrogen-dependent neoplasia
• Undiagnosed abnormal genital bleeding
• Hepatic adenomas or carcinomas
• Cholestatic jaundice of pregnancy or jaundice with prior OCP use
• Other endocrine causes of amenorrhea, e.g.
• hyperprolactinemia
• hypothyroidism or hyperthyroidism
• Cushing's syndrome
• congenital adrenal hyperplasia (elevated 17 OH progesterone)
