There are about 340 clinical studies being (or have been) conducted in Malawi. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to determine if extended antiretroviral regimens given to the infant during the first 14 weeks of age would decrease breast milk transmission of HIV.
The purpose of this study is to determine the best time to begin anti-HIV treatment in individuals who have HIV and tuberculosis (TB). Study hypothesis: Immediate antiretroviral therapy (ART), initiated after approximately 2 weeks of TB treatment, will reduce the frequency of other AIDS-defining illnesses and death in HIV-infected participants being treated for TB by at least 40% at week 48 when compared to deferred ART, initiated at after 8-12 weeks of TB treatment.
In clinical trials being conducted throughout the world, pregnant HIV-infected women are given anti-HIV drugs before, during, and after they give birth to prevent mother-to-child transmission of HIV. However, the effects of this anti-HIV treatment on infants is unknown. The purpose of this study is to determine the safety, toxicity, and potential side effects of maternal anti-HIV treatment on infants born to these HIV-infected women. Study hypothesis: Specific combination antiretroviral regimens used in clinical trials in diverse areas of the world are safe and well tolerated during pregnancy and breastfeeding periods, and are not associated with adverse side effects to the fetus, neonate, and/or breastfeeding infant. These regimens are associated with reduction of mother-to-child HIV transmission.
HIV infected pregnant women may take single-dose nevirapine (SD NVP) prior to giving birth to prevent mother-to-child transmission (MTCT) of HIV. However, SD NVP may cause NVP resistance in the mother, potentially ruling out some treatment options in the future. The purpose of this study is to determine which of three anti-HIV drug regimens most effectively reduces the development of maternal NVP resistance in HIV infected pregnant women. The effectiveness of short-term (7 day therapy) versus long-term (21-day therapy) regimens will also be compared. The study hypotheses are: 1) intrapartum SD NVP with a 21-day course of antiretroviral therapy (ART) results in less frequent selection of NVP-resistant HIV-1 variants than intrapartum SD NVP with a 7-day course of ART, and 2) a 7- or 21-day course of lamivudine/zidovudine (3TC/ZDV), emtricitabine/tenofovir disoproxil fumarate (FTC/TDF), or lopinavir/ritonavir (LPV/r) following SD NVP will not select nucleoside reverse transcriptase inhibitor (NRTI)- or protease inhibitor (PI)- resistant HIV-1 variants.
The purpose of this study is to determine how often dementia and other neurological problems occur in people with HIV. Participants of ACTG A5175 will enroll in this study.
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.
This study compared 3 different three-drug combinations in HIV infected individuals starting their first HIV treatment regimens. Participants were recruited from resource-limited areas in Africa, Asia, South America, Haiti, and also from the United States. The study hypothesis was each of the once daily combinations (PI based, or NNRTI based) would not have inferior efficacy compared to the twice daily NNRTI based combination.
This study will determine whether anti-HIV drugs can prevent the sexual transmission of HIV among couples in which one partner is HIV infected and the other is not.
The majority of HIV infected people worldwide became infected with the virus through heterosexual contact. BufferGel and PRO 2000 Gel are vaginal gels designed to prevent women from becoming infected with HIV during sexual intercourse with an HIV infected partner. This study will test the safety and effectiveness of these gels.
The study will determine whether a daily vitamin and mineral supplement (a multivitamin including Vitamin A) will improve health when added to standard chemotherapy for tuberculosis. This study will compare the effectiveness of the multivitamin in HIV infected and HIV uninfected patients.
