| NCT00001202 ↗ | Treatment of Boys With Precocious Puberty | Completed | Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) | Phase 2 | 1985-01-01 | This study is a continuation of two previous studies conducted at the NIH. The first study , "Treatment of True Precocious Puberty with a Long-Acting Lutenizing Hormone Releasing Hormone Analog (D-Trp(6)-Pro(9)-Net-LHRH)" had less than optimal results. Some patients, all of whom were diagnosed with familial isosexual precocious puberty, had an inadequate response to the medication and were observed to have high levels of testosterone, advanced bone aging, and other complications of the disease. As a result these patients were enrolled in a second study In the second study, "Spironolactone Treatment for Boys with Familial Isosexual Precocious Puberty", - the patients received another medication, spironolactone (Aldactone). The drug blocked the effects of testosterone, -but bone age advancement did not improve. Some patients began experiencing gynecomastia (an abnormal growth of the male breasts). Researchers believe these may be the effects of elevated levels of estrodiol (a form of the female hormone, estrogen). In the present study, testolactone is added to the drug regimen to block the production of estrogen. The study therefore uses spironolactone to prevent the action of the male hormones (androgen) and testolactone to block the production of female hormones (estrogen). Deslorelin, an LHRH analog which works by turning off true (central) puberty, is added to the drug regimen once true puberty begins. This is because it is know that boys with familial male precocious puberty go into true puberty too early (despite treatment with spironolactone and testolactone), and when that happens, the spironolactone and testolactone are no longer as effective. The goal of the treatment is to delay sexual development until a more appropriate age and prevent short adult stature (height). |
| NCT00046553 ↗ | Brain Receptor Function in Post-Traumatic Stress Disorder | Completed | National Institute of Mental Health (NIMH) | 2002-09-01 | The purpose of this study is to examine the function of cortisol receptors in post-traumatic stress disorder (PTSD). Patients with PTSD have neurobiological dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis function. High corticotrophin releasing hormone (CRH) levels and decreased hippocampal volume are major features of the disorder. The mechanisms responsible for these alterations are not known. This study will evaluate the function of cortisol receptors to determine their roles in maintaining PTSD HPA axis dysregulation. Three groups of subjects will take part in the study: Patients with PTSD, healthy control subjects who were exposed to trauma in the past and remained healthy and healthy control subjects who were never traumatized At study entry, the cerebral spinal fluid (CSF) of all participants will be sampled and evaluated. Participants will also undergo a magnetic resonance imaging (MRI) scan of the brain as well as eye blink trace conditioning and neuropsychological tests. Participants will be admitted to the Clinical Center for two nights on three different occasions. At each overnight visits, blood levels of stress hormones will be measured every hour for 26 hours after medication or placebo are given. This will be the end of the study for both groups of healthy control subjects, with the exception that they may be asked to repeat neuropsychologic and eye blink tests after 12 weeks. Participants with PTSD will receive paroxetine for 10 weeks. After 10 weeks these participants will be reevaluated in exactly the same way as before treatment (except they will not repeat the MRI scan). | |
| NCT00123955 ↗ | PIE II: Pharmacological Intervention in the Elderly II | Completed | National Institute on Aging (NIA) | Phase 3 | 2005-04-01 | The purpose of this study is to examine whether spironolactone will improve exercise tolerance and quality of life in elderly patients with heart failure preserved ejection fraction (HFPEF). |
| NCT00123955 ↗ | PIE II: Pharmacological Intervention in the Elderly II | Completed | Wake Forest School of Medicine | Phase 3 | 2005-04-01 | The purpose of this study is to examine whether spironolactone will improve exercise tolerance and quality of life in elderly patients with heart failure preserved ejection fraction (HFPEF). |
