NCT02931539
The purpose of this study is to compare the efficacy of maribavir to investigator-assigned anti-Cytomegalovirus (CMV) therapy in CMV viremia clearance in transplant recipients who are refractory or resistant to prior anti-CMV treatment.
NCT00485264
Integrase is 1 of 3 HIV (Human Immunodeficiency Virus)-1 enzymes required for viral replication. Raltegravir is a drug that prevents integrase from working properly. This drug has been tested for safety and efficacy in adults, but this is the first study to examine raltegravir in children and adolescents. The purpose of this study was to determine the appropriate dose for raltegravir across the pediatric age range from 4 weeks to 18 years of age, by acquiring short and long term safety data, intensive and population pharmacokinetic (PK) data, and efficacy experience with raltegravir in HIV-infected children and adolescents.
NCT00000651
To evaluate the safety of zalcitabine (dideoxycytidine; ddC) alone and in combination with zidovudine (AZT) versus AZT alone when administered to asymptomatic patients with a CD4 count = or \< 200 cells/mm3 and symptomatic patients with a CD4 count = or \< 300 cells/mm3. To compare the effectiveness of ddC alone and in combination with AZT versus AZT alone. ddC has been shown to demonstrate an antiviral effect. AZT has been shown to significantly decrease mortality and reduce the frequency of opportunistic infections in patients with AIDS or advanced ARC. After 1 year of AZT therapy, the effectiveness tends to diminish and patients progress with more opportunistic infections and higher mortality rates. Because of the demonstrated antiviral activity, absence of hematologic toxicity, and lack of cross tolerance in laboratory studies of ddC, a study to investigate the long-term effectiveness of ddC in patients with HIV infection who have received AZT therapy is warranted.
NCT00458393
The purpose of this study is to determine whether daily use of emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) can prevent HIV infection in men who also receive HIV counseling, condoms, and treatment for other sexually transmitted infections (STIs).
NCT00000696
To evaluate the anti-HIV effect of single agent versus combination therapy with zidovudine (AZT) and interferon alfa-2a (IFN-A2a), as measured by p24 protein expression, viral growth and infectivity in patients with symptomatic HIV disease. To assess the safety of low dose schedules of AZT and IFN-A2a, alone and in combination, as measured by neutrophil counts and hepatic transaminase levels. To evaluate the comparative effects of single agent versus combination therapy with AZT and IFN-A2a on CD4 cell counts and skin test reactivity. AZT is known to be an effective treatment for HIV infection. However, patients may develop reactions to AZT when it is administered for long periods of time. Combining AZT with another drug at lower doses might reduce toxicity in patients and prevent the development of drug resistant strains. IFN-A2a can reduce the growth of HIV in test tube experiments and recent studies have shown that when AZT and IFN-A2a are used together they reduce the growth of HIV more effectively than when either drug is used alone. This study will examine the effectiveness and safety of these drugs when they are given together and compare these results with the effectiveness and safety of the drugs when they are used alone.
NCT00140842
This study will examine hormonal differences in ghrelin and growth hormone in obese and normal weight adolescents and their relationship to body composition and insulin resistance. The study will also investigate the effect of the macronutrient composition of a meal on postprandial ghrelin levels and whether ghrelin responses will predict the degree of hunger and caloric intake at a subsequent meal.
NCT03337542
This study is enrolling participants by invitation only. This is an open-label, safety extension study for subjects who participated in the ARC007 study.
NCT01461096
Men who have sex with men (MSM) have an increased risk of developing anal human papillomavirus (HPV) infections, which can be a risk factor for anal cancer. HIV-infected women are also at risk of anal cancer. This study will evaluate the effectiveness of the Food and Drug Administration (FDA)-approved quadrivalent HPV vaccine, Gardasil, at preventing anal HPV infection in HIV-infected MSM and HIV-infected women.
NCT02965781
This study evaluates the safety and efficacy of SADBE in the prevention of recurrent herpes labialis in adults. Two-thirds of the participants will receive a SADBE solution, while the other third will receive only the vehicle as a placebo control. The solutions will be administered topically to the patient's arms. The study will compare a single-arm application versus a two-arm application versus two placebo doses on the arm.
NCT00088153
This study is to determine the effects of anorexia nervosa on bone mass and hormone levels in adolescents. Whether administration of estrogen, a normal hormone present during puberty, can help maintain bone development in girls with anorexia nervosa will be determined.
NCT00000625
To determine the efficacy and safety of zidovudine ( AZT ) versus didanosine ( ddI ), AZT plus ddI, and AZT plus zalcitabine ( ddC ) in preventing disease progression in HIV-infected patients with CD4 counts of 200-500 cells/mm3.
NCT00082498
New treatment options are critical for treatment-experienced HIV infected patients with drug resistance. HIV entry inhibitors have been shown effective in patients with resistance to other anti-HIV drugs. This study will test the safety and effectiveness of three different doses of vicriviroc (formerly known as Schering D, SCH-D, or SCH 417690) in HIV infected patients.
NCT00125099
The purpose of this study is to evaluate whether the HIV vaccine VRC-HIVDNA009-00-VP will be safe in individuals who started antiretroviral therapy during acute HIV-1 infection. The study will also test whether the vaccine can increase the immune system function in these participants.
NCT00031044
Even though powerful anti-HIV drug combinations have been successful in patients with little or no prior anti-HIV therapy, studies have shown that these treatments are less effective in patients who have been treated with nucleoside analogues. This study will test the safety and effectiveness of adding one or two new drugs to a personalized anti-HIV regimen for patients whose previous HIV treatments have failed.
NCT00075829
The study is designed as a Phase III, multi-center trial of tandem autologous transplants versus the strategy of autologous followed by Human Leukocyte Antigen (HLA)-matched sibling non-myeloablative allogeneic transplant. Study subjects will be biologically assigned to the appropriate arm depending on the availability of an HLA-matched sibling. There is a nested randomized phase III trial of observation versus maintenance therapy following the second autologous transplant for patients on the tandem autologous transplant arm.
NCT03694210
A prospective, single arm, open label, multi-center, trial to evaluate the safety and effectiveness of the Interscope EndoRotor® Resection System in subjects requiring direct endoscopic necrosectomy (DEN) with walled off pancreatic necrosis (WOPN).
NCT00107549
The purpose of this study is to determine the safety of two recombinant HIV vaccines in HIV infected young adults on stable anti-HIV therapy.
NCT01276249
The Aptus Endosystems STAPLE International Post-Market Registry is intended to expand the clinical knowledge base by including 'real world' subjects.
NCT03480763
This study is designed 1) to evaluate the safety, tolerability, and immunogenicity of V114 and Prevnar 13™, 2) to describe the safety of sequential administration of V114 or Prevnar 13™ followed by PNEUMOVAX™23, and 3) to evaluate the immune responses to the 15 serotypes contained in V114 when PNEUMOVAX™23 is given approximately 12 months after receipt of either V114 or Prevnar 13™ in healthy adults 50 years of age or older. There was no formal hypothesis testing.
NCT02698475
