There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This randomized phase III trial is studying high dose interferon alfa to see how well it works compared to observation only in treating patients with stage II or stage III melanoma that has been completely removed by surgery.
This research study evaluates an experimental device for the treatment of the depressed phase of Bipolar Disorder Type II. Repetitive Transcranial Magnetic Stimulation (rTMS) is an experimental procedure where a device delivers an alternating magnetic field to a focal area of the brain. When the coil is placed against the scalp on the left frontal area of the head, the magnetic field is focused to a region of the brain that is thought to be involved in depression. This study is intended to test if rTMS can affect this region of the brain in a way that improves the symptoms of depression related to Bipolar Disorder Type II. The purpose of this study is to obtain safety and efficacy information regarding the use of rTMS(Repetitive Transcranial Magnetic Stimulation) for patients in the depressed phase of Bipolar Disorder Type II.
Primary Objective: 1. To study ex-vivo purging of autologous hematopoietic stem cells that will be used to support high-dose chemotherapy in patients with chronic myelogenous leukemia (CML). Major endpoints are neutrophil engraftment and survival. Secondary Objectives: 1. To evaluate the toxicity of ex-vivo purged autologous cells when used to support high-dose chemotherapy. 2. To evaluate the rate and duration of cytogenetic remissions achieved with this strategy. 3. To determine the time to platelet recovery to 20,000/mm3. 4. To determine the one-year survival rate.
RATIONALE: Stereotactic radiation therapy may be able to send x-rays directly to the tumor and cause less damage to normal tissue. Giving stereotactic radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase I trial is studying the side effects and best dose of stereotactic radiation therapy in treating patients with kidney tumors.
The exposure of human beings to markedly altered environments (ambient pressure and inhaled gas mixtures) has profound effects on their innate immune capacity to effectively combat viral illnesses. This Phase IIA clinical trial examines the effects of an exposure to a 4 atmospheric environment has on HIV-infected humans whose clinical condition has progressed to formal AIDS status.
The principal investigator hypothesizes that participants receiving NSAID drugs with dyspeptic symptoms have increased production of gastric levels of free radicals. The primary objective of the study is to determine if Esomeprazole Magnesium increases gastric total antioxidant capacity and decreases gastric free radical production in humans. Participants (age 18 years and older) with no history of upper GI bleeding who are receiving non-steroidal anti-inflammatory drugs and then develop dyspepsia will be recruited from our primary care clinic in Washington, DC. All eligible participants will undergo biopsies of antrum and corpus. The participants will be randomized to receive either Zantac OTC or Nexium for 15 days. On day 15, all participants will undergo repeat upper endoscopy to obtain biopsies of antrum and corpus. Tissue samples will then be extracted to determine total antioxidant capacity and lipid peroxide levels (as an indirect marker of free radical production).
The purpose of this research study is to determine whether Carvedilol, an FDA approved beta blocker, when administered for an 8-week period to veterans currently undergoing treatment for methamphetamine dependence (1) improves their ability to stay in treatment longer, (2)eases the aversive symptoms that accompany stimulant withdrawal, and (3) increases the time they remain abstinent from methamphetamine.
Preeclampsia is a hypertensive disorder of pregnancy and a leading cause of fetal and maternal morbidity and mortality. Recent findings indicate preeclampsia is an inflammatory disorder associated with increased expression of COX-2. This study will test the hypothesis that treatment of women with a COX-2 inhibitor, celecoxib, will stop the inflammatory process and reverse symptoms of preeclampsia.
Individuals with schizophrenia frequently have impairments in attention. These impairments have been shown to be related to overall functioning. Some research suggests that Olanzapine may be associated with improvement in various aspects of attention. The primary purpose of this study is to determine whether switching from a typical antipsychotic to Olanzapine improves task engagement. Individuals who taking typical antipsychotics will be randomly assigned to either 1) remain on their typical antipsychotic medications, or 2) be switched from their typical antipsychotic medications to Olanzapine. All participants will be enrolled in a twice-weekly 20 session cognitive training program that is specifically designed to target attention deficits and promote active engagement. Improvements in attention will be compared between individuals who remained on their typical antipsychotic medications and those that were switched to Olanzapine.
The purpose of the study is to find out the effect of replacing testosterone in the form of a gel (Androgel®) on the amount of fat mass in males with low testosterone and diabetes.
