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.
This protocol concerns the implementation and evaluation of an intervention designed to realign the existing cadre of Community Health Workers (CHW) in Neno District, Malawi to better support the care needs of the clients they serve. The proposed intervention is a 'Household Model' where CHWs will be assigned to households, rather than HIV or TB specific patients, and will be trained to provide support for a wider range of conditions including HIV, hypertension, diabetes, and pediatric malnutrition. The new model is designed to improve retention in care for clients with chronic, non-communicable diseases, along with increased uptake of women's health services and treatment for pediatric malnutrition, while sustaining the high retention rates for clients in the HIV program. Eleven sites (health centres and hospitals) were arranged into six clusters by estimated size of the catchment area populations, with a population range of 11,680 to 26,260 and an average population of 20,400. The order in which the intervention will be rolled out across the sites will be randomized so that the intervention can be evaluated in a stepped-wedge cluster randomized controlled trial. These clusters were grouped based mostly on geographic location but also on catchment area sizes, in order to maximize feasibility of training for the CHW team and not overload CHW training sessions with too many trainees.
This is an unblinded cluster-randomized study to evaluate the effectiveness of two strategies for scripting/dispensing of antiretroviral therapy (ART) on retention, virologic suppression, and cost compared to the standard of care. The study will be conducted in Malawi and Zambia among approximately 8,200 HIV-1-infected adults (18 years or older) who are stable on ART. Clusters will be randomized to one of three study arms: (1) standard of care (SOC) ART scripting (varies by country, region, clinic, and/or provider), (2) three-month ART scripting, and (3) six-month ART scripting. 30 clusters will be selected for the study, 15 in Malawi and 15 in Zambia, and will be randomized to a study arm.
An appropriate balance of omega-6 and omega-3 fatty acids is important for support of neurocognitive development in healthy infants and toddlers. In young children recovering from severe acute malnutrition (SAM), excess omega-6 intake depletes omega-3 fatty acid status. This research will evaluate how novel ready-to-use therapeutic foods (RUTF) with balanced fatty acids improve the metabolic and neurocognitive effects in young children in Malawi recovering from SAM, yielding new knowledge that also has implications for development of well-nourished children.
This cluster-randomized controlled trial will evaluate the effectiveness of a four-day hospital-based intervention program for primary caregivers of children with severe malnutrition.
The primary purpose of this study is to assess the preventive vaccine efficacy (VE), safety and tolerability of a heterologous prime/boost regimen utilizing Ad26.Mos4.HIV and aluminum-phosphate adjuvanted Clade C gp 140 for the prevention of Human Immuno Virus (HIV) infection in HIV-seronegative women residing in sub-Saharan Africa from confirmed HIV-1 infections diagnosed between the Month 7 and Month 24 visits.
This project aims to evaluate the performance characteristics of rapid tests to differentiate bacterial from non-bacterial infection in febrile adults and children presenting at OPDs (outpatient departments) i.e.("fever triage assays") in three LMICs. The evaluation will include a different commercial biomarker combinations as well as individual biomarkers to assess their individual or combined value in the target population. Markers will be evaluated onsite in ELISA or RDT format, as appropriate. Further, this study aims to contribute to a centralized biobank of well-characterized specimens for use by IVD companies and academic institutions for the development and evaluation of emerging assays.
Over 1.5 billion people are infected with soil-transmitted helminths (STH). Global STH guidelines recommend MDA (mass drug administration) of albendazole or mebendazole to targeted populations, including pre-school age children and school-age children. However mathematical models suggests that current MDA strategies are not sufficient for interrupting disease transmission in most areas. Meanwhile many lymphatic filariasis (LF) programs have successfully treated entire populations with albendazole (in combination with ivermectin or diethylcarbamazine) and are transitioning to a state of post-MDA surveillance. This project will conduct a series of community-based cluster randomized trials in India, Malawi, and Benin to determine if maintaining three years of MDA with albendazole to entire communities following the cessation of LF programs can interrupt STH transmission in focal geographic areas. Additionally, this study aims to compare the efficacy of community-wide MDA versus targeted MDA of children in interrupting the transmission of STH. Nested implementation science research will be used to optimize the intervention, identify contextual factors influencing trial efficacy, and evaluate the feasibility of sustaining and scaling community-wide MDA for STH. These data will provide evidence necessary to inform future guidelines, policies, and operational plans as country partners engage in intensified approaches to eliminate these disabling diseases.
This study aims to compare the efficacy of monthly IPTp-DP with monthly IPTp-SP to determine if IPTp-DP is associated with a reduction in malaria infection at delivery among HIV-negative women in an area with high levels of SP resistance in Malawi.
The purpose of this study is to evaluate the impact of dextrose administration in severely sick children admitted to hospital with low-glycaemia. The problem: Mortality in children remains high in sub-Saharan African hospitals. While antimalarial drugs, antibiotics and other definitive treatments are well understood, the role of emergency care with supportive therapies such as maintaining normal glucose and electrolyte balances, has been given limited attention. Hypoglycaemia is common in children admitted to hospital in low-income settings. The current definition of hypoglycaemia is a blood glucose level of less than 2.5mmol/l. Outcomes for these children are poor, with a mortality rate of up to 42%. An increased mortality has also been reported among acutely ill children with low-glycaemia, defined as a blood glucose level of 2.5-5.0mmol/l. The reason for increased mortality rates is not fully understood. Study objective: To determine the impact on mortality of a raised treatment cut-off level for paediatric hypoglycaemia, from 2.5mmol/l to 5.0mmol/l. Methodology: Severely ill children admitted to two central Malawian hospitals; Queen Elisabeth Central Hospital, Blantyre and Zomba Central Hospital, with low-glycaemia (2.5-5.0mmol/l) will be randomised into intervention or control groups. The intervention group will be treated with an intravenous bolus of 10% dextrose 5ml/kg followed by a dextrose infusion in addition to standard care while the control group will receive standard care only. Children will be followed until discharge from hospital or death. Primary end-point is in-hospital mortality.
The goal of this evaluation is to assess the impact of a 3.5 year, World Food Program (WFP) supplemental child feeding and nutrition services program in reducing stunting and improving linear growth in children from 6 through 24 months of age in a rural district of Malawi.
