There are about 116 clinical studies being (or have been) conducted in Zimbabwe. 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 TAME study will evaluate four new approaches which will be compared against the standard care currently in use in the treatment of malnutrition enteropathy in children with severe acute malnutrition. A high pathogen burden causes damage to the intestinal mucosa which exacerbates nutritional impairment and leads to further susceptibility to infection and impaired epithelial regeneration. Enteropathy is characterised by multiple epithelial breaches, microbial translocation from gut lumen to systemic circulation and systemic inflammation.The trial will evaluate the potential impact of four interventions (colostrum, N-acetyl glucosamine, teduglutide, and budesonide) given for 14 days, which aim at mucosal restoration. The trial will determine if repairing damage to the small intestinal mucosa leads to the reduction of systemic inflammation and thus lessening the nutritional impairment, and so if this contributes to the reduction of mortality in children. In Zambia only, endoscopic biopsies and confocal laser endomicroscopy will be used to evaluate response and confirm safety at a mucosal level. Identifying an agent or agents which contribute most to mucosal healing will then ultimately lead to further large phase 3 trial in which the agent(s) will be further evaluated. The trial also anticipates to gain a more in depth understanding of pathophysiology and may identify where current management strategies of treating malnutrition enteropathy in children are failing.
The aim of the study is to examine the effect of a psychological intervention on antiretroviral therapy outcomes and symptoms of common mental health disorders among adults living with HIV and common mental disorders in rural Zimbabwe.
The MTN-041 study is a multi-site exploratory study using focus group discussions (FGDs) and in-depth interviews (IDIs) to identify individual, interpersonal, social and cultural factors that may affect potential uptake of two safe and effective HIV prevention products, the monthly dapivirine (DPV) vaginal ring (VR) and daily oral pre-exposure prophylaxis (PrEP), by pregnant and breastfeeding women in Africa.
This phase II clinical trial studies the side effects of pomalidomide and how well it works in treating patients with Kaposi sarcoma and human immunodeficiency virus (HIV) infection. Biological therapies, such as pomalidomide, may stimulate the immune system in different ways and stop tumor cells from growing and it may also block the growth of new blood vessels necessary for tumor growth.
Primary Objective The purpose of this study is to evaluate the impact of an interactive VMMC education session offered by a circumcised health worker and contribution to transport costs for accessing VMMC along with either (1) conditional economic compensation for wages or (2) lottery-based economic incentives on the uptake of VMMC. Hypothesis VMMC education session offered by a role model - a young male health worker who has been previously benefited from VMMC services in this community - addressing risks of HIV infection, benefits of VMMC, and the fear of pain associated with VMMC, with/without a conditional fixed or lottery-based financial incentives off-setting present-biased preferences, will improve risk perception and increase uptake of VMMC in HIV-negative young men. Study outcomes The primary outcomes for the study will be risk perception measured in a follow-up survey at 6 months and proportion of men taking up VMMC within 6 months measured through self-reports and matched to program records.
Primary Objective: The purpose of this trial is to evaluate the impact of an interactive tablet based counselling session correcting risk perception and addressing ambiguity around availability, usability and effectiveness of PrEP on PrEP uptake within 6 months in adolescent girls and young women (AGYW) aged 18-24 years. Hypothesis: Correcting misperceptions of risks of HIV infection and off-setting ambiguity effects about the availability, usability and efficacy of PrEP, through localized, interactive, tablet-based counselling, will increase uptake of PrEP in HIV-negative AGYW. Study outcomes: The primary outcomes for the study will be risk perception measured in a follow-up survey at 6 months and proportion of women taking up PrEP within 6 months measured with biomarkers of plasma antiretroviral (ARV) drug presence.
This study is a field experiment in peri-urban and rural communities near Harare, Zimbabwe, that seeks to estimate the likelihood that individuals will purchase HIV self-tests under various pricing and distribution strategies. About 4,000 adults will be randomly selected, administered a short questionnaire, and given vouchers that will offer them HIV self-tests at randomly allocated prices and distribution sites. The study will also test whether the provision of HIV self-tests can be targeted more cost-effectively to reach high-risk persons and non- recent testers. Last, the study will explore whether demand for repeated HIV self-testing is contingent on the price offered initially.
Background Postpartum haemorrhage (PPH) is a major cause of maternal mortality worldwide accounting for 25% of maternal deaths. In Zimbabwe PPH is the second most common cause of death. Tranexamic acid (TXA) is widely used to reduce blood loss in elective surgery, bleeding trauma patients, and menorrhagia. The investigators seek to determine the efficacy of TXA in reducing PPH during and after elective caesarean section. Methods and Design The investigators intend to perform an open label randomized control study of 1,162 women who are undergoing elective caesarean section. The participants will be randomly selected to receive an intravenous infusion of TXA 10 minutes prior to skin incision or not to receive the intervention. Prophylactic oxytocin will be administered to all the women. The primary outcome will be incidence of PPH defined by blood loss equal to or more than 1,000ml calculated by determining the difference in haematocrit values taken prior to and 48 hours after caesarean section. Discussion In addition to prophylactic uterotonic administration, TXA is a complementary component acting on the haemostatic process that can be used in the third stage of labour to prevent PPH. It is a promising intervention that is cheap, easy to administer and would be easy to add to routine delivery protocols in hospitals. It would also help to conserve precious resources by reducing the need for blood products, and expensive surgical interventions to manage PPH. This large adequately powered randomized study seeks to determine the efficacy of TXA to validate its routine use at caesarean section to prevent PPH.
The purpose of this study is to evaluate the pharmacokinetics, feasibility, acceptability, and safety of a fixed-dose combination of emtricitabine and tenofovir disoproxil fumarate (FTC/TDF) as oral daily pre-exposure prophylaxis (PrEP) to prevent HIV during pregnancy and postpartum in adolescents and young women and their infants.
Investigators propose to assess the sensitivity, specificity, positive and negative predictive value of an HIV Risk Screening Tool in identifying the risk of being HIV-infected among Orphans and Vulnerable Children (OVC) aged 2-18 years in a community setting.
