There are about 117 clinical studies being (or have been) conducted in Botswana. 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.
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.
The purpose of this study is to evaluate the safety of and immune response to an alphavirus replicon, HIV-1 subtype C gag vaccine, AVX101, in HIV uninfected adults in the United States, South Africa, and Botswana.
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.
Tuberculosis (TB) is highly endemic in sub-Saharan Africa. The increased burden of TB in settings with high prevalence of the Human Immunodeficiency Virus (HIV) is associated with high rates of transmission of Mycobacterium tuberculosis (M.tb) to both adults and children. Children infected with TB have a higher risk of developing severe disease than adults with TB. The purpose of this study was to determine if the antibiotic isoniazid (INH) prevented TB infection in infants born to HIV-infected mothers.
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 purpose of this study is to test the safety of an HIV DNA vaccine (EP HIV-1090) and to test whether or not the vaccine can stimulate immune system responses in HIV uninfected people. This vaccine uses only parts of the virus's DNA and cannot cause HIV infection.
IMPAACT P1026s is a Phase IV prospective clinical study to evaluate the pharmacokinetics (PKs) of antiretroviral (ARV) and tuberculosis (TB) medications in pregnant women and their infants. (Pharmacokinetics are the various interactions between a drug and the body.) This study also evaluated the PKs of certain ARVs in postpartum women before and after starting hormonal contraceptives. The PKs of these drugs were evaluated by measuring the amount of medicine present in blood and/or vaginal secretions.
