NCT00002441
The purpose of this study is to see if an HIV vaccine, AIDSVAX B/B, can protect adults who are at risk from becoming infected with HIV. Patients who become infected despite immunization will be studied to see if receiving the vaccine before becoming infected will help keep HIV levels (viral load) low.
NCT00002156

NCT00006439
Adherence to complex medication regimens is critical to successful treatment of HIV infection. Unfortunately, adherence to medical regimens with conventional interventions averages 50% in chronic disease. We have observed that adherence barriers that were unrecognized by providers in the clinic setting have been detected during home visits. It is possible that recognition and interventions to resolve adherence barriers observed during home visits may improve adherence. This proposal will test the hypothesis that home-visits which identify previously unrecognized adherence barriers and provide support and education will increase medication adherence among children and youth with HIV infection and improve the patient/health care provider relationship. Specific aims of the study are: 1. Determine the impact of a series of home-visits on adherence to medication regimens for HIV infected youth and children. 1a. Adherence to medical regimens will be assessed before and after the series of home-visits using a self-report questionnaire and Microelectronic Monitoring System (MEMS) or in-home pill count. 1b. For each of these measures a percentage of adherence will be calculated and compared from a baseline to after the final home visit and after the six month follow up period. 2. Assess the changes in patient satisfaction from baseline to after the home-visits using a questionnaire completed by the patient/family. 3. Incorporate a pilot study to assess the changes in the provider's knowledge of the patient's family characteristics and home circumstances relevant to adherence following the home visits.
NCT00000780
PRIMARY: To identify, characterize, and co-enroll HIV-infected adolescents into existing and future ACTG (or other NIH-sponsored) HIV treatment protocols through the systematic and recurrent assessment of eligibility. To assess the ability of adolescents enrolled in ACTG 220 to adhere to ACTG (or other NIH-sponsored) HIV treatment protocols; and to define factors that influence the adolescent's ability to enter or adhere to study protocols. SECONDARY: To describe the nature, stage, and progression of HIV infection in adolescents. Little is known about HIV-infected adolescents as a group and, as a result, small numbers of them are currently enrolled in ACTG drug studies. Creative approaches are needed to encourage enrollment of HIV-infected adolescents whose socio-demographic profile has made access to NIH-sponsored research unlikely.
NCT00002234
The purpose of this study is to see if it is safe and effective to give HIV-infected patients a new combination of anti-HIV drugs taken once daily.
NCT00002378
To determine the proportion of patients whose plasma HIV-1 RNA level falls below the level of detection (\< 400 copies/ml) at week 24 of study therapy. To determine the absolute change in plasma HIV-1 RNA during the 24 weeks of study treatment. To collect safety data on the treatment regimens. AS PER AMENDMENT 12/12/97: To compare the virologic response of Fortovase (FTV) (Saquinavir) Soft Gel Capsule (SGC) tid plus nucleoside reverse transcriptase inhibitors (NRTIs) versus FTV bid plus NRTIs. Further, to compare the virologic response of FTV tid plus NRTIs versus FTV bid plus Nelfinavir bid plus a NRTI with respect to: the percentage of patients whose plasma HIV-1 RNA level falls below the Amplicor assay level of detection (\< 400 copies/ml) at week 24 and week 48.
NCT00002330
To compare the time to progression of Cytomegalovirus (CMV) retinitis among each of three doses of oral ganciclovir, as well as to intravenous therapy, when given as maintenance for 26 weeks. To compare the safety and tolerance among oral doses of ganciclovir at the study doses, as well as to intravenous therapy, when administered as maintenance for 26 weeks.
NCT00000155
To describe the clinical course of keratoconus and to describe the relationships among its visual and physiological manifestations, including high- and low-contrast visual acuity, corneal curvature, slit lamp biomicroscopic findings, corneal scarring, and quality of life. To identify risk factors and protective factors that influence the severity and progression of keratoconus.
NCT00008554
The purpose of this study is to compare GW433908 and nelfinavir when each is given with abacavir and lamivudine to HIV patients who have not taken antiretroviral drugs.
NCT00001995
To determine if a drug regimen containing rifabutin will eradicate or decrease the numbers of Mycobacterium avium complex (MAC) organisms in blood, improve the symptoms associated with MAC infection, and increase survival in patients with AIDS. To assess the safety of the drug regimen.
NCT00032279
The purpose of this phase II study is to evaluate an investigational monoclonal antibody for the treatment of glucocorticoid-refractory Graft Versus Host Disease (GVHD). Patients diagnosed with GVHD who have not responded satisfactorily to, or are intolerant of, treatment with standard agents will be considered for entry. Patients will be allowed to continue on their other immunosuppressive drugs at stable doses during the trial. The research is being conducted at up to 20 clinical research sites in the US.
NCT00002265
To demonstrate that zalcitabine (dideoxycytidine; ddC) monotherapy is safe and tolerable in the treatment of patients with AIDS or advanced AIDS related complex (ARC) who previously demonstrated intolerance to zidovudine (AZT) treatment while in Protocol N3300 (NIAID ACTG 114) or N3492 (NIAID ACTG 119). NOTE OF CAUTION FOR CONCOMITANT MEDICATIONS ON STUDY: Patients on amphotericin, pyrimethamine, sulfadiazine, trimethoprim/sulfamethoxazole, ganciclovir, intravenous pentamidine, intravenous acyclovir or oral acyclovir or other bone marrow or renal toxic drugs may not tolerate concomitant ddC. If these drugs are given concomitantly with ddC, patients should have frequent clinical and laboratory assessments, as appropriate. Drugs that are nephrotoxic or have the potential to cause peripheral neuropathy might be expected to cause increased toxicity when co-administered with ddC. Drugs that could cause serious additive toxicity when co-administered with study medication will be allowed for treatment of an acute intercurrent illness or opportunistic infection at the discretion of the investigator. Their use may be allowed with interruption of study drug for up to 35 days per episode, for a total of 90 days for the study. If the patient's condition requires chronic administration of these medications, the patient will be discontinued from study medication and followed.
NCT00008489
The purpose of this study is to compare gastrointestinal (stomach and intestines) side effects of 2 forms of Videx in HIV-infected patients. Videx can be an effective anti-HIV treatment but many patients will not take the medication due to its side effects. Videx EC is a capsule form of the drug and may have fewer side effects. Also, patients would not have to take as many pills since patients taking Videx EC would have to take only 1 capsule per day instead of 2 tablets per day. This study will see if patients taking Videx EC have fewer side effects.
NCT00001018
To determine the pharmacokinetic profile of single doses of letrazuril in patients with AIDS-related cryptosporidial diarrhea; to determine the dose proportionality of single escalating doses of letrazuril; to determine steady-state concentrations of letrazuril; to evaluate the safety and efficacy of escalating doses of letrazuril, compared with placebo, for patients with AIDS-related cryptosporidial diarrhea. Letrazuril, the p-fluor analog of diclazuril, has been shown in an animal model to prevent infections by organisms closely related to the intracellular parasite Cryptosporidium. Reliable data are needed to show the effectiveness of letrazuril in treating AIDS-related cryptosporidial diarrhea.
NCT00002213
The purpose of this study is to see if it is safe and effective to give 1592U89 plus 141W94 plus DMP 266 to patients with HIV who have developed resistance to indinavir, ritonavir, saquinavir, or nelfinavir after at least 20 weeks of protease inhibitor treatment. This study also examines how long this combination therapy is effective before patients develop resistance to it.
