HIV InfectionThe purpose of this study is to determinate the effectiveness, safety and tolerability (how well the body accepts the drug) of an investigational Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI) called TMC125.
Evaluation of Two Anti-HIV Treatment Strategies in Resource-Limited South African Communities
HIV InfectionsThe purpose of this study is to determine the effectiveness of several anti-HIV treatment strategies in resource-poor South African communities. The strategies being studied are using specially trained doctors or nurses to administer HIV care.
"The Once A Day Protease Inhibitor Regimens"
HIV InfectionsAtazanavir (ATV) and fosamprenavir (fAPV) are new protease inhibitors that can be administered once-a-day and boosted with ritonavir (r). Prior studies have demonstrated that both are effective in treatment of ARV-naïve HIV-infected people. This study was designed to demonstrate if a HAART regimen containing ATV/r is not inferior to a HAART regimen containing fAPV/r, in ARV-naïve patients over a 96-week period. This is a phase IV, single center, randomized, open label, 2-arm clinical trial in ARV therapy-naïve patients with HIV-1 RNA >1,000 copes/mL and CD4 cell count <350 cells/mm3. Patients will be randomized to receive tenofovir and emtricitabine plus either ATV (300mg qd) and ritonavir (100mg qd) or fAPV (1400mg qd) and ritonavir (200mg qd).

ARVs to Prevent Breastmilk HIV:Viral and Immune Responses
HIV InfectionsIdentifying new approaches for preventing breastmilk transmission of HIV-1 is an important research priority. To this end, clinical trials are underway to evaluate the efficacy of HAART (zidovudine, lamivudine, nevirapine) during late pregnancy/lactation versus zidovudine/nevirapine peripartum for prevention of breastmilk HIV-1 transmission. It is important to understand the mechanism of effect of these antiretroviral (ARV) strategies on prevention of breastmilk HIV-1 transmission. This phase II trial will compare HAART vs peripartum zidovudine/nevirapine for effect on breastmilk HIV-1, breastmilk HIV-1 specific immune responses, and infant HIV-1 specific immune responses. 100 pregnant HIV-1 seropositive women in Nairobi with CD4 counts between 200 to 500 who have chosen to breastfeed will receive either ARV regimen. Mother-infant pairs will be followed for 1 year after delivery. Home visits will be conducted in the first month (~10 visits) to collect 2-5 mls of breastmilk per visit. Mother-infant pairs will be seen in the study clinic with maternal blood and breastmilk and infant blood collected at months 1, 3, and 6 for HIV-1 and HIV-1 Elispot assays. Breastmilk HIV-1 RNA and DNA levels will be quantified in Dr. Overbaugh's laboratory in Seattle and Elispot assays conducted in Nairobi with validation of a subset in Dr. Rowland-Jones laboratory in Oxford. Viral loads, decay curves, half-life, and re-population following ARV cessation will be estimated for each regimen and regimens compared. These studies will provide insight into the viral and immune responses to ARV regimens proposed for prevention of breastfeeding HIV-1 transmission and will be important for rational design of future interventions. After taking into account, estimated loss to follow-up, the targeted sample size with outcome data was 80 women, 40 in each trial arm, estimating undetectable breast milk HIV-1 RNA levels in the HAART arm and median breast milk HIV-1 RNA levels of 3.0 log10 in women receiving ZDV/NVP.
Randomised Trial of Structured Treatment Interruption of HAART in HIV-Infected Adults in Abidjan...
HIV InfectionsInterrupting HAART during limited periods of time ("structured treatment interruption : STI") could entail benefits (better long term tolerance, lower drug-induced viral resistance, lower cost) but also concomitant risks (lower efficacy, higher drug-induced viral resistance). At present, the benefit/risk ratio of STI is unclear. Several STI trials are in progress in industrialised countries. This trial aim at assessing the benefits and risks of two different STI strategies in West Africa.
Induction-maintenance of Lopinavir/r in HIV-infected Subjects
HIV InfectionsThis study will assess the safety, tolerability and antiviral activity of a simplified PI-based treatment regimen (Kaletra,ä) compared to conventional HAART regimens in patients infected with HIV-1 who are on their first boosted-PI antiretroviral treatment regimen. The potency of the antiviral activity of Kaletra has been clearly demonstrated in a wide spectrum of patients in a number of different clinical trials.6-9 The durable viral suppression seen after 4 years of therapy10 proves that it can provide effective, long-term treatment for people with HIV-1. Data from one of these trials (M97-720),6 an ongoing Phase II study of lopinavir/ritonavir in combination with NRTIs suggests there may be a role for monoclass therapy with Kaletra in the treatment of HIV-1-infection.
Effect of Addition of Raltegravir (MK-0518) to PI- or NNRTI-Based ART Regimens in HIV Infected Subjects...
HIV InfectionsRaltegravir (MK-0518) is an HIV-1 integrase inhibitor with potent in vitro activity against HIV-1 strains including those resistant to currently available antiretroviral drugs. The purpose of this study is to assess the effectiveness of raltegravir in further reducing viral load in HIV infected patients that have already achieved viral suppression below the level of detection of standard viral load assays when added to antiretroviral therapy (ART).
