There are about 292 clinical studies being (or have been) conducted in Zambia. 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 whether the addition of tenofovir (TDF) and emtricitabine (FTC)to a standard PMTCT regimen containing single-dose nevirapine (NVP) can reduce the development of post-ingestion HIV resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs).
The University of Washington has received funding to conduct a proof-of-concept trial to assess the impact of suppression of genital herpes on HIV infectiousness. This study (the Partners in Prevention Study) will enroll HIV discordant heterosexual couples in which the HIV-infected partner is co-infected with herpes simplex virus type 2 (HSV-2) to test the efficacy of twice daily (bid) acyclovir (400 mg) given to the HIV-infected partner to prevent transmission to his/her HIV negative partner(s). This randomized, double-blind, placebo-controlled proof-of-concept trial will provide evidence for the efficacy of HSV-2 suppression with daily acyclovir on HIV transmission among HIV-discordant couples among whom the HIV-positive partner is also HSV-2 seropositive with CD4 >250. The researchers hypothesis is that, by decreasing the frequency and amount of genital HIV shedding, standard doses of daily acyclovir 400 mg bid will reduce the rate of HIV transmission by 50% in HIV-discordant couples among whom the HIV-infected partner is HSV-2 positive. Under the study protocol version 4.1.1, 3000 HIV-discordant heterosexual couples in which the HIV-positive partner is HSV-2 positive and has a CD4 count >250 will be recruited; participants will be followed for up to 2 years. A 4% per year HIV incidence in the placebo arm is assumed. The first study site began enrolling participants on 17 November 2005. As of September 2006, 14 sites in Eastern and Southern Africa had participated in recruiting the 2300 HIV-discordant couples enrolled to date.
This study assesses the efficacy and safety of olmesartan medoxomil in children ages 1-16 with high blood pressure. After a 5-week blinded treatment period of up to 5 weeks participants can continue to take olmesartan medoxomil (OM) for up to an additional 46 weeks.
In developing countries, neonatal death from birth asphyxia is a major problem. This study will be conducted in several countries to determine if the combined Neonatal Resuscitation Program/Essential Newborn Care Program compared to the new World Health Organization (WHO) basic perinatal care education of health care providers (Essential Newborn Care Program) results in reduced mortality due to perinatal asphyxia.
Smoking can contribute to many health problems for mothers and their babies. In developing countries, there is little information about the number of pregnant women that smoke and the reasons why some pregnant women choose to smoke. The purpose of this multi-site tobacco use survey is to obtain information on knowledge, attitudes and behaviors among pregnant women in diverse populations regarding tobacco products.
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.
Asphyxia is a leading cause of neonatal death in Zambia. This study will be conducted in two cities in Zambia to determine if the combined Neonatal Resuscitation Program/Essential Newborn Care Program compared to the new World Health Organization (W.H.O.) basic perinatal care education of health care providers (Essential Newborn Care Program) results in reduced mortality due to perinatal asphyxia.
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.
The primary objective is to confirm the hypothesis that azithromycin plus chloroquine is non-inferior to mefloquine for the treatment of symptomatic, uncomplicated malaria due to P. falciparum.
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.
