NCT00001181 ↗	Testolactone for the Treatment of Girls With LHRH Resistant Precocious Puberty	Completed	Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)	Phase 2	1982-10-01	The normal changes of puberty, such as breast enlargement, pubic hair and menstrual periods, usually begin between the ages of 9 and 15 in response to hormones produced in the body. Some children's bodies produce these hormones before the normal age and start puberty too early. This condition is known as precocious puberty. The hormones responsible for the onset of puberty come from the pituitary gland and the ovaries. The hormones from the pituitary gland act on the ovaries to produce different hormones that cause the breasts to grow, pubic hair to develop, and menstruation. Many children with precocious puberty can be treated with a medication known as lutenizing hormone-releasing hormone analog (Lupron, Histerelin, Deslorelin). This drug is made in a laboratory and is designed to act like the natural hormone LHRH, which is made in the pituitary gland. The drug causes the pituitary gland to decrease the amount of hormones it is releasing and thereby decrease the amount of hormones released by the ovaries. However, some girls already have low levels of pituitary hormones and yet their ovaries still produce hormones. Researchers do not believe that LHRH analog therapy will work for these children. Testolactone is a drug that acts directly on the ovary. It works by preventing the last step of estrogen production in the ovary. The goal of this treatment is to stop estrogen production and delay the onset of puberty until the normal age. Researchers will give patients with LHRHa resistant precocious puberty Testolactone for six months. If the initial treatment is successful and patients do not experience very bad side effects, they will continue to receive the medication until puberty is desired. Throughout the therapy patients will receive frequent monitoring of their general state of health, hormone levels, and medication levels.
NCT00001259 ↗	A Treatment Study for Premenstrual Syndrome (PMS)	Completed	National Institute of Mental Health (NIMH)	Phase 1	1992-08-11	This study examines the effects of estrogen and progesterone on mood, the stress response, and brain function and behavior in women with premenstrual syndrome. Previously this study has demonstrated leuprolide acetate (Lupron (Registered Trademark)) to be an effective treatment for PMS. The current purpose of this study is to evaluate how low levels of estrogen and progesterone (that occur during treatment with leuprolide acetate) compare to menstrual cycle levels of estrogen and progesterone (given during individual months of hormone add-back) on a variety of physiologic measures (brain imaging, stress testing, etc.) in women with PMS. PMS is a condition characterized by changes in mood and behavior that occur during the second phase of the normal menstrual cycle (luteal phase). This study will investigate possible hormonal causes of PMS by temporarily stopping the menstrual cycle with leuprolide acetate and then giving, in sequence, the menstrual cycle hormones progesterone and estrogen. The results of these hormonal studies will be compared between women with PMS and healthy volunteers without PMS (see also protocol 92-M-0174). At study entry, participants will undergo a physical examination. Blood, urine, and pregnancy tests will be performed. Cognitive functioning and stress response will be evaluated during the study along with brain imaging and genetic studies.
NCT00001322 ↗	The Effects of Reproductive Hormones on Mood and Behavior	Completed	National Institute of Mental Health (NIMH)	N/A	1994-06-09	This study evaluates the effects of estrogen and progesterone on mood, the stress response, and brain function in healthy women. The purpose of this study is to evaluate how low levels of estrogen and progesterone (that occur during treatment with leuprolide acetate) compare to menstrual cycle levels of estrogen and progesterone (given during individual months of hormone add-back) on a variety of physiologic measures (brain imaging, stress testing, etc.) in healthy volunteer women without PMS. This study will investigate effects of reproductive hormones by temporarily stopping the menstrual cycle with leuprolide acetate and then giving, in sequence, the menstrual cycle hormones progesterone and estrogen. Tests (such as brain imaging or stress testing, etc.) will be performed during the different hormonal conditions (low estrogen and progesterone, progesterone add-back, estrogen add-back). The results of these studies will be compared between women without PMS and women with PMS (see also protocol 90-M-0088). At study entry, participants will undergo a physical examination. Blood, urine, and pregnancy tests will be performed. Cognitive functioning and stress response will be evaluated during the study along with brain imaging and genetic studies.
