Active clinical trials for "HIV Infections"

This study will evaluate the safety of and immune responses to a dendritic cell vaccination for HIV-1 infection. The vaccine will be made from a patient's own cells combined with small fragments of HIV-1 (made synthetically in a laboratory). These cells will be administered back to the patient either into a vein (intravenously) or the skin (subcutaneously).

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.

This study was designed to evaluate and compare safety, tolerability of subjects who successfully suppress HIV-1 on their first PI regimen to those who switch to fosamprenavir. This is a 48-week study, where subjects who were assigned to be in their original PI-group have the option of switching to fosamprenavir on week 24. Prior to being assigned their treatment group, subjects had to be suppressed for at least three months. All subjects also take a background regimen of two nucleoside/nucleotide reverse transcriptase inhibitors.

Androgen deficiency in HIV-infected women is associated with sarcopenia and may cause critical reductions in physical functioning and reduced bone density. The effects of long-term androgen therapy on lean body mass, bone density and other clinical endpoints including quality of life, functional status and neurocognitive function in HIV-infected women are not known.

It is probable that a mucosal approach is necessary for a prophylactic HIV vaccine protecting against sexually transmitted infection. Mucosal immune responses have been almost non-existent in trials of HIV vaccine candidates in which the antigen was delivered systemically. This study will test the safety and immune response of a recombinant HIV-1gp160 by nasal and mucosal routes alone or formulated with DC-Chol in healthy volunteers.

The purpose of this study is to evaluate virological efficacy and safety of two double protease inhibitor regimens: atazanavir/fosamprenavir/ritonavir 300 mg once daily/ 700/100 mg twice daily, versus atazanavir/saquinavir/ritonavir 300/1500/100 mg once daily in protease inhibitor naive HIV-1 patients.

This study will assess the safety and efficacy of once-daily administration of Fuzeon compared with twice-daily administration in HIV-1 infected patients who have received prior treatment. Patients will also receive an optimized treatment consisting of antiretroviral (ARV) therapy as determined by the treating physician. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are commonly included in anti-HIV drug regimens. However, HIV infected women who have previously taken the single dose NNRTI nevirapine (SD NVP) for the prevention of mother-to-child transmission (MTCT) of HIV may not respond as well to NNRTIs as women who have never taken NVP. Another class of anti-HIV drugs, protease inhibitors (PIs), may be more effective for women who have previously taken NNRTIs. This study will compare the effectiveness of NNRTI- and PI-based regimens in women who have taken NVP for prevention of MTCT of HIV. This study will also compare regimens including an NNRTI with regimens including a PI in women who have never taken NVP.

To investigate safety, tolerability and antiviral activity in Non-nucleoside reverse transcriptase inhibitor (NNRTI)-experienced HIV-1 infected patients

The purpose of conducting this already-FDA approved Phase I clinical trial is to evaluate the safety and efficacy of etanercept (Enbrel) on the response rate in HIV-infected subjects who have failed to respond to conventional antiretroviral (HAART) therapy and for whom no alternative therapy exists. The greatest challenge faced by HIV-treating clinicians today is the management of virologic failure and metabolic complications of anti-HIV treatment. Treatment failure can occur because of non-compliance, drug discontinuation, lack of drug potency, inadequate drug plasma concentration or drug resistance. Of these, drug resistance remains the single most important reason for virological failure and rapidly limits treatment options.
