NCT01317147
The morbidly obese frequently present with mood and anxiety disorders, which are often treated with serotonin reuptake inhibitors (SRI) antidepressant drugs. The investigators hypothesized that gastric bypass surgery would decrease the absorption of SRI. The investigators also wished to determine whether a reduction in SRI levels would increase the likelihood of worsening depressive symptoms.
NCT01049126
The purpose of this study is to assess the relationship of assay sensitive patients versus assay resistant patients with progression free survival.
NCT00000979
To compare the effectiveness and toxicity of didanosine (ddI) and zidovudine (AZT) in patients with AIDS, advanced AIDS-related complex (ARC), or asymptomatic infection with CD4 counts \< 200 cells/mm3. AZT is effective in reducing mortality in patients with AIDS who receive the drug after the first episode of Pneumocystis carinii pneumonia (PCP) and in patients with advanced ARC. However, AZT therapy has been associated with significant toxicities. In addition, the effectiveness of AZT appears to decrease during the second and third years of therapy. For these reasons, the development of alternative therapy that would be at least as effective but less toxic is of great importance. The drug ddI is an antiviral agent that inhibits replication (reproduction) of HIV with less apparent toxicity than AZT.
NCT00000672
AMENDED: 8/29/90 Inclusion of asymptomatic patients with CD4 counts less than 200 cells/mm3. Standardization of baseline evaluation schedule to allow 14 days prior to study dosing. Reduction in frequency and intensity of follow-up evaluations. Standardization of study endpoints. Inclusion of toxicity scoring and management for amylase and triglyceride elevations. Clarification of concomitant medication use. Original design: To determine the effectiveness of didanosine (ddI) in patients with AIDS or advanced AIDS related complex (ARC) who have documented hematologic intolerance to zidovudine (AZT) therapy. To determine if the efficacy of ddI increases with increasing doses. AZT is effective in reducing mortality in patients with AIDS who receive the drug after the first episode of Pneumocystis carinii pneumonia (PCP) and in patients with advanced ARC. However, AZT therapy has been associated with significant toxicities. In addition, the effectiveness of AZT appears to decrease during the second and third years of therapy. For these reasons, the development of alternative therapy that would be at least as effective but less toxic is of great importance. The drug ddI is an antiviral agent that inhibits replication (reproduction) of HIV with less apparent toxicity than AZT. The major dose-limiting toxicities found in the Phase I studies have been pains in the feet and legs of 2 patients initially receiving 12 mg/kg/day and 12 patients receiving daily doses of 25.8 to 51.2 mg/kg; symptoms began 8 to 27 weeks after initiating ddI treatment. These neuropathy-like symptoms have generally not been associated with significant abnormalities in nerve conduction studies and patients have reported marked improvement in symptoms within 1 to 2 weeks of discontinuing ddI. Some patients have resumed ddI treatment at a reduced dose after resolution of their symptoms. Studies indicate that ddI remains active in the body for at least 12 hours. This indicates that benefits of ddI might be achieved with a low frequency of drug administration.
NCT00000671
To compare the effectiveness and toxicity of didanosine (ddI) and zidovudine (AZT) in patients with AIDS or advanced AIDS-related complex (ARC) who have tolerated AZT therapy for 12 months or longer. Per amendment, asymptomatic patients with CD4 counts less than 200 cells/mm3 are eligible. AZT is effective in reducing mortality in patients with AIDS who receive the drug after the first episode of Pneumocystis carinii pneumonia (PCP) and in patients with advanced ARC. However, AZT therapy has been associated with significant toxicities. In addition, the effectiveness of AZT appears to decrease during the second and third years of therapy. For these reasons, the development of alternative therapy that would be at least as effective but less toxic is of great importance. The drug ddI is an antiviral agent that inhibits replication of HIV with less apparent toxicity than AZT. Studies indicate that ddI remains active in the body for at least 12 hours; thus benefits of ddI might be achieved with a low frequency of drug administration.
NCT00123890
The purpose of this study is to determine eligibility for one of three treatment studies of the CCR5 antagonist GW873140 or an observational study without GW873140. No investigational treatment will be administered through this study.
NCT00739739
The purpose of this study is to determine whether PD 0299685 is effective in the treatment of symptoms associated with interstitial cystitis/painful bladder syndrome, such as pain, urinary urgency and frequency. At the same time assess the drug's safety and tolerability.
NCT00468286
The study will have two treatment groups, evaluating two Degarelix doses. First dose is the initial dose followed by a maintenance dose given every three months. The initial dose given to suppress the testosterone level and the three month maintenance dose to maintain the suppressed testosterone level over one year of treatment.
NCT00001017
To compare the safety and effectiveness of a new drug, fluconazole, with that of the usual therapy, amphotericin B, in the prevention of a relapse of cryptococcal meningitis (CM) in patients with AIDS who have been successfully treated for acute CM in the last 6 months. Cryptococcal meningitis is a life-threatening infectious complication of AIDS. Because relapse after treatment occurs in over 50 percent of cases, chronic maintenance therapy with intravenous (IV) amphotericin B is usually given. However, amphotericin B is not always effective, has toxic effects, and must be given by the intravenous route. Fluconazole is an antifungal agent that can be given orally and has been shown to be effective against cryptococcal infections in animals and against acute CM in a few AIDS patients. Also, the side effects experienced by over 2000 patients or volunteers given fluconazole have seldom been severe enough to require withdrawal of the drug.
NCT00025558
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation or bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combining temozolomide, thiotepa, and carboplatin followed by peripheral stem cell transplantation or bone marrow transplantation in treating patients who have brain cancer.
NCT00000982
AMENDED 07/07/93: To evaluate whether continuous infusion AZT will impact neurodevelopmental deficits associated with HIV infection or alter rate of encephalopathy progression in children who have failed to improve or shown progression of these deficits despite optimal AZT therapy. AMENDED: To assess whether didanosine (ddI) will be better tolerated than AZT administered by either continuous intravenous delivery or oral administration (ddI arm removed per amended version).To determine whether ddI will achieve comparable clinical efficacy as the continuous intravenous route of delivery of AZT, and to assess whether either or both of these regimens are superior to that achieved with an intermittent AZT dosage schedule. To determine whether there are differences in patient or parent (guardian) compliance between the three treatment regimens. Original design: To determine whether the pharmacokinetic profile (bloodstream levels) of zidovudine (AZT) influences its effectiveness on HIV infection in children. That is, the study seeks to find out whether there is a difference in the effect of AZT when given as a continuous intravenous infusion (and, if available, an oral sustained release dose) compared to an intermittent (not continuous) dose given orally every 6 hours. The study also plans to determine (1) whether there are differences in the tolerance and side effects associated with AZT when given on an intermittent schedule as opposed to a steady-state schedule; (2) the extent of variation from patient to patient in AZT levels and whether the plasma and cerebrospinal fluid levels of AZT are related to the degree of therapeutic effectiveness; and (3) whether there are differences in the response of children who acquired HIV infection perinatally (just before, during, or just after the time of birth) versus those who acquired HIV infection by transfusion. One of the most serious effects of HIV disease in children is neuropsychological deterioration (relating to mental and nervous system functioning). This complication affects the vast majority of HIV infected children. A previous study of continuous intravenous administration of AZT in pediatric patients with HIV infection showed consistent and dramatic improvements of symptoms in all patients that had shown neurodevelopmental deficits or abnormalities. These improvements were seen within 3 to 4 weeks after AZT treatment was started. Neurodevelopmental improvements have been sustained on AZT, usually showing steady improvement which, in some patients, was associated with restoration of pre-HIV intellectual and neurological function. This study also showed an increase in the IQ scores of children receiving continuous infusion of AZT who did not have overt clinical evidence of encephalopathy (disease of the brain). Thus changes in cognitive function may be among the earliest signs of AIDS encephalopathy and underscores the need to start therapies that will treat the central nervous system in patients who appear to be clinically intact. A study comparing continuous infusion to intermittent dosing of AZT showed a significant increase in IQ scores for those children receiving the continuous dose compared to those treated with the intermittent schedule. Although a portable infusion pump allows patients to receive continuous infusion of AZT, a sustained release oral formulation that could provide a continuous release of AZT into the bloodstream would be highly desirable.
NCT00000688
To provide information about the usefulness and safety of giving injections of ganciclovir (DHPG) for treating peripheral cytomegalovirus (CMV) retinitis. CMV retinitis is an important sight-threatening opportunistic infection which affects 1 to 2 out of every 10 patients with AIDS. Results from an earlier study suggest that about 80 percent of patients with CMV retinitis will be helped by receiving intravenous doses of DHPG.
