Active clinical trials for "HIV Infections"

GSK has in-licensed a novel NNRTI-class candidate (GSK2248761, IDX12899) for the treatment of subjects with HIV-1 infection from Idenix Pharmaceuticals. Idenix Pharmaceuticals completed a proof-of-concept study evaluating GSK2248761 monotherapy over seven days in forty treatment-naïve subjects infected with HIV-1. GSK2248761 doses sequentially evaluated were 800 mg QD, 400 mg QD, 200 mg QD and 100mg QD. This study will evaluate a lower dose, or doses, of GSK2248761 to better characterize the dose-response and concentration-response curves. The results from this study will be used to select doses for future clinical studies in HIV-1 infected subjects.

This single arm study will evaluate the efficacy, safety and tolerability of a new investigational protease inhibitor (PI) plus background antiretrovirals plus Fuzeon (90mg sc bid) in HIV-1 infected, triple-class treatment-experienced, Fuzeon-naive adults. The new investigational PI will be administered according to the procedures of the early access program in which the patient is enrolled. The anticipated time on study treatment is 3-12 months, and the target sample size is approximately 120 individuals.

This study will investigate the safety and efficacy of raltegravir as a therapy for HIV-infected patients failing current therapy with 3-class antiviral resistance.

Human immunodeficiency virus (HIV)-1 infected participants receiving long-term therapy with lamivudine or emtricitabine (nucleoside reverse transcriptase inhibitors [NRTIs]) are at risk for the development of a mutation at position M184 on the HIV reverse transcriptase gene. This mutation confers resistance to both drugs (>100 fold increase in the concentration of drug producing 50% inhibition [IC50]). In-vitro studies with elvucitabine have shown that HIV-1 isolates with the M184V mutation show only a 10-fold increase in IC50 as compared to wild type HIV-1. Alexion Pharmaceuticals Inc. intention is to demonstrate that 10 milligrams (mg) of elvucitabine, administered once per day for 14 days with continued background anti-HIV-1 medications, will demonstrate a fall in HIV-1 ribonucleic acid (RNA) plasma levels, as compared to baseline. The data from this study will guide dosing in future long-term studies in HIV-1 infected participants with the M184V mutation.

This study will test whether a vaccination schedule of experimental HIV vaccines is safe and whether it causes side effects in healthy adult volunteers. It will also compare the effects of vaccine injected into the muscle (intramuscular), just under the skin (subcutaneous), or into the skin (intradermal) and will monitor the social impact of being in an HIV vaccine study. Healthy volunteers 18-50 years old may be eligible for this 42-week study. Participants are screened for antibodies to adenovirus, a common virus that causes upper respiratory infections, such as the common cold. Half of the participants selected will be positive and half will be negative for antibodies to the virus. The vaccines used in this study are known as VRC-HIVDNA016-00-VP (called the "DNA vaccine") and VRC-HIVADV014-00-VP (called the "rAd5 vaccine"). The DNA vaccine codes for four HIV proteins. The rAd5 vaccine is made using an adenovirus that has been modified to contain DNA that codes for three HIV proteins. These vaccines cannot cause HIV or adenoviral infections. Participants are randomly assigned to one of six possible vaccination schedules that include "prime" and "booster" vaccines. The first vaccinations prime the immune system and the immune response is then boosted later. The groups differ in the type of vaccines given (DNA vaccine prime with rAd5 booster or rAd5 prime with rAd5 booster), in how the vaccine is administered (intramuscularly, subcutaneously or intradermally) and in the schedule of administration. All shots are given in the upper arm. Subjects fill out a diary card at home for 5 days after each vaccination, recording their temperature and any symptoms. The cards are turned in to the clinic at the first visit after all 5 days are completed. Subjects return for clinic visits about 3 days after each prime vaccination and either come in or call the clinic about 7 days after the injection. They call a study nurse 1 or 2 days after the booster vaccination. Participants have 15-20 clinic visits during the course of the study, depending on their vaccination schedule. At each visit, they are checked for health changes or problems, asked how they are feeling and if they have taken any medications or other treatments, including over-the-counter medicines, herbal supplements, etc. Blood and urine samples are collected at some visits. Subjects are tested for HIV several times and asked questions about their sexual behavior and drug use. Throughout the stu...

The purpose of this study is to examine the efficacy of providing two levels of psychosocial support along with buprenorphine/naloxone (BUP) maintenance to opioid dependent patients receiving their care in an HIV clinical care setting.

The purpose of this study is to assess the safety and efficacy of tenofovir disoproxil fumarate (tenofovir DF; TDF) plus a genotype-guided optimized background regimen (OBR) compared to placebo plus OBR in the treatment of human immunodeficiency virus type 1 (HIV-1) infected antiretroviral treatment-experienced adolescents with plasma HIV-1 ribonucleic acid (RNA) levels greater than or equal to 1000 copies/mL.

Study the efficacy of Saquinavir/Ritonavir when given in single therapy as maintenance therapy, compared to standard HAART therapies.

Many patients who already harbor drug-resistant HIV require interruption of HAART due to poor compliance, poor quality of life, toxicity or development of resistance. In these patients interruption of HAART has a negative impact on patient immune status due to the reemergence of wild-type virus which is in general more pathogenic than HIV isolates containing resistance mutations. There is a need for "bridging" antiretroviral regimens that might prolong time off conventional HAART whilst waiting for a new regimen that is either fully suppressive or less toxic or less demanding for the patient.

Most anti-HIV regimens include a non-nucleoside reverse transcriptase inhibitor (NNRTI); however, some individuals fail on these regimens. The purpose of this study is to evaluate the safety and effectiveness of the protease inhibitor (PI) lopinavir/ritonavir (LPV/r) in HIV infected individuals who are failing an anti-HIV regimen that includes an NNRTI.
