NCT00053638
This is a 48-week study to evaluate the safety and efficacy of a new tablet formulation containing two FDA-approved drugs in HIV-infected patients who have not received prior therapy. This tablet will be taken with one of two FDA-approved drugs as a once-daily regimen. Study physicians will evaluate subjects to determine if they have certain medical conditions, laboratory test values, medication use, or drug allergies that would exclude them from the study.
NCT01026727
This phase 2b study is designed to assess the long-term efficacy (24 weeks) of MPC-4326 in combination with a 2-3 drug optimized background regimen (OBR) relative to the efficacy of a 3-4 antiretroviral (ARV) regimen in treatment experienced, HIV-1 infected subjects.
NCT00244712
This study was designed to test the safety and effectiveness of EPZICOM(abacavir/lamivudine) and TRUVADA (emtricitabine/tenofovir) for the treatment of HIV infection when both are used in combination with KALETRA (lopinavir/ritonavir) over 96 weeks
NCT00135395
The purpose of this study is to compare the anti-HIV efficacy, safety and effect of serum lipids of two boosted protease inhibitor-based HAART regimens (ARV/RTV v. LPV/RTV) in HIV-1 infected subjects who have experienced their first virologic failure while receiving a NNRTI-containing HAART regimen.
NCT00120393
Patients with HIV who are virologically suppressed on a lopinavir/ritonavir combination highly active antiretroviral therapy (HAART) regimen but with elevated non-HDL cholesterol are randomized to remain on lopinavir/ritonavir or change to atazanavir/ritonavir in combination with current nucleoside reverse transcriptase inhibitors (NRTIs).
NCT00511368
The purpose of this study is to evaluate antiretroviral activity of up to five different oral doses administered for two weeks of bevirimat versus placebo in HIV treatment experienced patients, who have documented genotypic resistance to at least one major mutation from the IAS-USA list (2007)of resistance mutations for NRTIs, NNRTIs, or PIs. Patients will also be monitored for side effects, and the pharmacokinetics of bevirimat will be determined.
NCT00321438
The purpose of this study is to measure viral tropism over time in subjects with X4-tropic or non-phenotypeable virus while receiving standard of care therapy. This is an observational study. No investigational treatment will be administered through this study.
NCT00408538
This study is the first to try this product in the rectum of humans. This study is only to find out if the gel is safe for use in the rectum, not to see if the gel works. Information gathered from this study will help investigators decide whether this gel is safe enough to move onto the next phase of studies. Information gathered from this study will also help investigators determine what participants did and did not like about the product and what types of products people might want to use in the future. Currently condoms and abstinence are the only methods proven to prevent the spread of HIV sexually.
NCT00342602
This study will identify genetic factors associated with the development of progressive multifocal leukoencephalopathy (PML) in patients with acquired immunodeficiency syndrome (AIDS). PML is a life-threatening infection of the brain that affects about 5 percent of untreated patients with AIDS. Its symptoms include mental deterioration, vision loss, speech disturbances, ataxia (inability to coordinate movements), paralysis, and coma. PML is caused by a polyomavirus called the JC virus. It is estimated that up to 80 percent of the human population has been exposed to the JC virus, but the disease is very rare. The virus only becomes active in people who have compromised immune systems, such as those undergoing immune suppressive chemotherapy for cancer and those with damaged immune systems due to HIV. Patients who have participated in the Multicenter AIDS Cohort Study may be eligible for this study, as well as healthy normal volunteers who will serve as controls. The study will review clinical information from patients and analyze genetic factors from both patients and control subjects to investigate genes associated with AIDS and JC virus infection.
NCT00000751
To evaluate the effect of anti-HIV immune serum globulin (HIVIG) versus immune globulin (IVIG) administered during pregnancy and to the newborn, in combination with zidovudine (AZT) administered intrapartum and to the newborn, on incidence of HIV infection in infants born to HIV-infected women who received AZT during pregnancy for medical indications. Vertical transmission of HIV from mother to child may occur before, during, or after parturition (via breast-feeding). It is believed that therapy administered both during pregnancy and intrapartum may help prevent vertical transmission. Additionally, adjunctive short-term antiretroviral therapy for the newborn, following the intensive viral exposure presumed to occur at birth, may be necessary.
NCT00004736
The purpose of this study is to see if a type of anti-HIV therapy called HAART is effective in lowering levels of HIV and boosting the immune system in HIV-infected patients with tuberculosis (TB). HIV-infected patients with TB have higher levels of HIV and lower CD4 cell counts (cells in the body that fight infection) than HIV-infected patients without TB. HAART has been effective in reducing HIV levels and increasing CD4 cells in patients without TB. However, its effects in HIV-infected patients with TB are unknown.
NCT00001132
The purpose of this study is to see if adding 1 drug to an anti-HIV drug combination early in treatment against HIV can lower the viral load (amount of HIV in the blood) to a level so low that it cannot be measured (undetectable). The drug that will be added to a treatment is abacavir (ABC). Many patients who take 3 anti-HIV drugs together are able to achieve very low viral loads, for example, viral loads below 50 copies/ml. However, some patients taking only 3 drugs are not able to achieve a viral load this low. Doctors hope that, by adding the drug ABC to a current treatment, a viral load below 50 copies/ml can be achieved. Doctors would like to find out if it is effective to start patients on 3 drugs and then add another drug (treatment intensification) if the treatment is not working as well as hoped.
NCT00000966
To evaluate the effectiveness and toxicity of oral azithromycin and pyrimethamine as acute therapy for toxoplasmic encephalitis in AIDS patients. To assess the toxicity and effectiveness of azithromycin alone as maintenance therapy. Encephalitis caused by Toxoplasma gondii is the most frequent cause of focal central nervous system infection in patients with AIDS. Untreated, the encephalitis is fatal. Standard treatment for toxoplasmic encephalitis is associated with serious adverse effects. Thus, alternative treatments are needed.
NCT00075062
Microbicides are drugs that destroy microbes such as viruses and bacteria. Rectal microbicides may be able to prevent transmission of HIV during anal intercourse. The purpose of this study is to obtain rectal samples from men to learn information that may be valuable in future clinical trials of rectal microbicides.
NCT00000778
To evaluate the methodology for rapidly determining the early bactericidal activity (EBA), tolerance, and pharmacokinetics of isoniazid and levofloxacin in the treatment of pulmonary tuberculosis (TB). Traditionally, in trials for treatment of TB, a new drug is administered in combination with two or more other antituberculous agents of known effectiveness over a long period of time. In this setting, it is difficult to determine the effect of any single drug or dose level. Development of new agents for the treatment of TB may be accelerated by a methodology in which a new agent could be evaluated for activity by administering it as a single agent over a short time period. This study utilizes a method to measure the amount of bacteria present each day in the lungs.
NCT00001117
This study evaluates patients infected with both HIV and Hepatitis C virus (HCV) who are receiving anti-HIV drugs. The purpose of this study is to learn more about HCV infection in patients whose HIV blood level decreases to less than 500 copies/ml.
NCT00000917
The purpose of this study is to set up a blood bank for infants who have HIV-positive mothers. This blood may be used in the future to treat the child if he/she turns out to be HIV-positive. Blood from the umbilical cord contains a certain kind of cell called a stem cell. Stem cells eventually turn into one of the many types of blood cells. If HIV infection can be prevented in these stem cells, then, when these stem cells are injected back into the infant, the new cells that develop will also be protected from HIV. This study will provide the blood needed to test whether this type of gene therapy is safe and effective.
NCT00001109
The purpose of this study is to learn more about some of the immune cells in the blood (CD4 cells, for example) of healthy children in order to better understand the differences in the blood cells of children infected with HIV. Because children's bodies are still developing, their cells are different from those of adults, and their bodies respond differently to infections such as HIV. In order to understand how immune cells grow and mature so that they can fight HIV, it is important to see how these cells behave in normal children.
NCT00002418
The purpose of this study is to see if it is safe and effective to give a new anti-HIV drug combination to HIV-infected patients who have never taken nonnucleoside reverse transcriptase inhibitors (NNRTIs) and who have failed to respond to protease inhibitors (PIs). The drug combination will contain didanosine (ddI) plus stavudine (d4T) plus nevirapine (NVP) plus MKC-442. Hydroxyurea (HU) may be added.
NCT00002420
The purpose of this study is to see if it is safe and effective to give MKC-442, didanosine (ddI), stavudine (d4T), and delavirdine (DLV) to HIV-positive patients.
