NCT00000893
Cohort I: The purpose of this study is to see how safe it is to combine 2 anti-HIV medications, efavirenz (EFZ) and nelfinavir (NFV) to treat HIV-positive children and to find an appropriate dose of EFZ to use in combination with NFV. Cohort II: The purpose of this study is to see how safe it is to give EFZ syrup combined with NFV and to measure the levels of EFZ and NFV in the blood. (This purpose reflects a change from the original since there are now 2 different cohorts of patients.) EFZ is an effective anti-HIV medication that easily can be combined with other drugs to treat HIV. This is an early study to determine a safe and effective dose for HIV-positive children. This study also will examine the correct dose of NFV to use in combination with EFZ.
NCT00000849
The purpose of this study is to determine the safety and maximum tolerated dose (the highest dose that can be given safely) of recombinant Interleukin-2 (rIL-2) in HIV-infected children. This study also evaluates the effect of rIL-2 on the immune system of these patients. IL-2 is a substance naturally produced by the body's white blood cells that plays an important role in helping the body fight infection. HIV-infected patients do not produce enough IL-2, and it is hoped that the use of rIL-2 may improve immune system function in these patients. First, it is necessary to determine the safety and effectiveness of this drug in HIV-infected children.
NCT02273726
The primary objective of this study is to evaluate the efficacy and safety of roxadustat compared with active control (epoetin alfa) for the maintenance treatment of anemia in participants with ESRD on dialysis.
NCT04531592
The purpose of this study is to find out if a drug called valproic acid (VPA) will protect organs (like the kidneys) from harmful effects caused by the temporary drop and then rise of blood flow and oxygen (called ischemia reperfusion (I/R) injury that sometimes happens during liver transplant surgery. VPA is an approved drug for treating conditions such as seizures and migraines for many years. However, it is not approved for use at the higher dose that will be used in this study or for protecting organs from I/R injury. This study will enroll liver transplant patients and randomly assign them to receive either VPA diluted in salt water or salt water without VPA (placebo) and then follow the patients and compare their organ function and overall outcome. This study is masked meaning that the patients, doctors, and nurses will not know which patient received which treatment. The study treatment will be given in addition to the care that liver transplant patients normally receive. The researchers doing this study believe that VPA will lessen organ injury caused by I/R, meaning that patients who receive VPA will experience less kidney injury when compared to patients who receive the placebo.
NCT00304395
The purpose of this research is to identify cases from patients who have been referred for consultation to the Infectious Disease Section at the VAMC, Houston, and to compare them with other cases of CAP in order to determine whether there are features that might enable non-CAP cases to be distinguished from CAP.
NCT00000815
To compare measles seroconversion rates (development of antibodies) at 13 months of age in HIV-infected and uninfected children on one of two immunization schedules: attenuated measles/mumps/rubella virus (M-M-R II) vaccine at 12 months versus attenuated measles vaccine (Attenuvax) at 6 months plus M-M-R II vaccine at 12 months. Recommendations for the age at vaccination should balance the need to minimize the risk of morbidity and mortality with the benefit of achieving the highest seroconversion rates. Immunizing a more intact immune system at an earlier stage of HIV infection may in turn achieve better and long-lasting measles protection. This study will help define a more effective measles vaccine regimen for children diagnosed with HIV infection and will provide greater insight into the functional status of the HIV-infected children's humoral immune system.
NCT01189266
This phase I/II trial studies the side effects and best dose of vorinostat and to see how well it works when given together with radiation therapy followed by maintenance therapy with vorinostat in treating younger patients with newly diagnosed diffuse intrinsic pontine glioma (a brainstem tumor). Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving vorinostat together with radiation therapy may kill more tumor cells.
NCT03897257
The study is being done to determine and compare the safety and effectiveness of an investigational combination therapy (low and high concentrations) versus mono-therapy (low and high concentrations) or mono-therapy (fixed concentration) in subjects with moccasin type tinea pedis.
NCT03797521
The purpose of this study is to explore the safety, tolerability and activity of SXC-2023 when dosed for 6 weeks versus placebo in adult patients with moderate to severe Trichotillomania.
NCT04718636
The purpose of this study is to evaluate the effect of CC-99677 coadministration on the pharmacokinetics (PK) of an oral contraceptive (OC).
NCT03324581
A trial to assess the safety and efficacy of OPC-64005 in the treatment of adult attention-deficit/hyperactivity disorder.
NCT00816062
The purpose of this study is to examine, through the endpoints established in this protocol, the long-term safety and effectiveness of the Talent Abdominal Stent Graft System, in a post-approval environment.
NCT00000839
To assess the pharmacokinetics, safety, and toxicity of intravenous and oral didanosine (ddI) administration in third trimester pregnant women who are HIV positive but are either intolerant or resistant to zidovudine (AZT). To collect data on infant toxicity following maternal treatment with ddI during the third trimester of pregnancy. AZT may not be the optimal antiretroviral agent for all pregnant women requiring therapy for HIV infection. Although ddI has been approved for use in HIV-infected adults and older children, the safety and pharmacokinetics of ddI in pregnant women has not yet been determined.
NCT00000793
To assess the efficacy, safety, and tolerability of amitriptyline hydrochloride versus mexiletine hydrochloride in reducing pain intensity in patients with HIV-related painful peripheral neuropathy. No large-scale controlled clinical trials of symptomatic therapy for painful HIV-related neuropathy have been attempted. Both amitriptyline and mexiletine have been useful in the management of painful neuropathies; however, both are associated with certain toxicities. In this comparative study of amitriptyline and mexiletine, benztropine mesylate also will be included as an active placebo to mimic the side effects of the study drugs.
NCT00000952
The study examines the safety and effectiveness of ritonavir (an anti-HIV drug), alone and in combination with other anti-HIV drugs, in HIV-positive children under 2 years of age. This study will also determine the most effective doses of ritonavir for future pediatric HIV studies. Infants infected with HIV by their mothers experience faster disease progression than adults or older children. Treatment with anti-HIV drugs administered at an early age may slow disease progression in infant populations.
NCT00000887
The purpose of this study is to see if giving nelfinavir (NFV) plus zidovudine (ZDV) plus lamivudine (3TC) to HIV-positive pregnant women and their babies is safe. This study will also look at how long these drugs stay in the blood. ZDV has been given to mothers in the past to reduce the chances of passing HIV on to their babies. However, better treatments are needed to further reduce these chances and to better suit the treatment needs of mothers and their children. Taking a combination of anti-HIV drugs during pregnancy may be an answer.
NCT00000773
To determine the safety, tolerance, and pharmacokinetics of a new improved microparticulate suspension formulation of atovaquone administered at one of two dose levels (per 09/30/94 amendment, a third dose level was added) daily for 12 days in HIV-infected and perinatally exposed (per 8/9/95 amendment) infants and children who are at risk of developing Pneumocystis carinii pneumonia (PCP). Atovaquone has shown prophylactic potential in adults in the treatment of PCP but is poorly absorbed in tablet form. To improve the bioavailability of atovaquone, a new formulation has been prepared as a microparticulate suspension. Since studies in adults have demonstrated substantial safety of this drug, evaluation in children is being pursued.
NCT00000807
To assess the toxicity, tumor response rate, and effect on quality of life of daily low-dose etoposide administered for 7 consecutive days every other week in patients with AIDS-related Kaposi's sarcoma that has relapsed or progressed after systemic chemotherapy. Etoposide may be at least as, or even more, effective and less myelotoxic when given in low doses over prolonged periods of time.
NCT00000864
The purpose of this study is to determine the safety, tolerance, and metabolism of single-dose and multiple-dose abacavir (ABC) in HIV-exposed infants receiving standard postnatal treatment with zidovudine (ZDV). This study also evaluates the correct dosages of ABC to be used in future studies. Early aggressive therapy may be the best chance to slow disease progression in infants who may have been infected with HIV by their mothers. Early HIV suppression may significantly reduce viral levels and allow for restoration of the immune system, providing improved control over HIV infection. Therefore, it is important that the safety and tolerance of ABC in combination with ZDV be examined as potential early therapy in newborn and young infants.
NCT02950012
The purpose of this study is to investigate the effects of OPTI-BIOME™ (Bacillus subtilis MB40), a probiotic supplement, on bloating, gas and abdominal discomfort symptoms in otherwise healthy adults.
