Clinical trials

The R-SWITCH intervention aims to address the low coverage of treatment for severe wasting (SAM) by leveraging existing community groups to deliver an integrated package focused on prevention, screening, referral, and treatment of SAM. It includes behavior change communication on child nutrition and health, active screening, improved passive screening at health posts, and follow-up of referred cases and those enrolled in outpatient treatment programs (OTP). The primary objectives of the R-SWITCH studies are to assess the intervention's impact on OTP coverage, identify implementation barriers and facilitators, and evaluate its cost-efficiency and cost-effectiveness.

Child wasting is a type of malnutrition which occurs when a child becomes too thin. This medical condition increases the risk of becoming sick or dying. A child with severe wasting needs to be seen in a medical consultation to check on health status and to receive some medicine and a medical food supplement for daily consumption until cured. Yet, only a small proportion of children suffering from severe wasting are presently receiving appropriate treatment. In Kenya, there is an opportunity to build on the existing network of community health promoters (CHPs) to increase the number of children with wasting who are identified and treated. In intervention areas, CHPs will be equipped with smartphones and an application which provides guidance on household members to visit and simple actions to take, related to health. CHPs will distribute color-coded mid-upper arm circumference tapes to households with young children and train caregivers on how to use it. After training, CHPs will send Short Message Services (SMS) to remind caregivers to regularly measure the arm circumference of the child. In addition, CHPs will receive a scale to measure the weight of children every month. Finally, wasted children registered in the treatment program who fail to attend a planned consultation will be flagged to their CHP through the phone application, and CHPs will conduct a specific home visit to investigate and help solve potential issues. The study will assess whether this community intervention (called SWITCH) allows to identify and treat more children suffering from severe wasting. Before the start of the intervention, the proportion of wasted children receiving treatment in 40 community units in Turkana South, Turkana East and Aroo will be assessed. After this survey, a computer will randomly select 20 community units where the intervention will be scaled up. The survey will be repeated after 2 years to assess if the proportion of severely wasted children receiving treatment is higher in the area where the intervention was scaled up compared to the area where it was not scaled up. In addition, after 1 year of implementation, the study will assess how the intervention was scaled up, what are the main challenges, and what are the overall perceptions on the intervention in the community among those who receive it and those who deliver it. Finally, costs of the various components of the intervention will be measured for all actors involved, including for caregivers.

This study aims to evaluate whether revised food voucher programs, combined with nutrition education sessions, can improve food security, dietary quality, nutrition knowledge, and nutritional outcomes among low-income households in the Philippines. Researchers will compare different monthly voucher amounts-Philippine Peso (PhP) 3,000, PhP 5,000, and PhP 8,000-with a no-voucher control group to determine which approach is most effective. The main questions the study aims to answer are: * Do food vouchers improve household food security, reduce hunger, and improve dietary quality and nutrient intake? * Do larger voucher amounts lead to greater improvements in nutrition and health outcomes? * Does enhanced nutrition education improve nutrition knowledge and healthy eating practices? Participants will: * Receive either a monthly food voucher or no voucher, depending on study group assignment * Attend nutrition education and Social and Behavior Change Communication (SBCC) sessions if assigned to a voucher group * Complete household interviews on food consumption, household expenditures, food security, and nutrition knowledge * Participate in dietary assessments and anthropometric measurements for women and children under 5 years of age

Severe acute malnutrition (SAM) places children at significant risk of mortality. Outpatient treatment programs are effective but there is a need to increase treatment coverage and reduce costs of treatment. Reducing the dosage of therapeutic food products and/or reducing visitation required by caregivers may be beneficial but evidence is limited on the treatment outcomes and costs of these approaches. This study will compare two dosage options (full vs reduced dosages) of the World Health Organization protocol for the treatment of SAM and high-risk moderate acute malnutrition (HR-MAM) to each other and to the Kenya national protocol (which involves reducing dosage, changing treatment product, and reducing visitation schedule during the course of the treatment once the SAM child reaches the criteria for moderate acute malnutrition before recovery), in terms of treatment performance and cost. We will conduct a cluster-randomized controlled trial including 45 facilities in Samburu, West Pokot, and Wajir sub-counties. Children 6-59 months old being admitted into outpatient treatment programs for SAM or HR-MAM will be enrolled. Outcomes will be recovery, default, death, transfer, and non-response rates; treatment adherence; mean amount of therapeutic products needed for recovery; mean length of stay; and anthropometry at discharge. We will conduct a costing study in which we will estimate the costs per child admitted into treatment and cost per treated child recovered. We will estimate the non-inferiority of each of the two WHO protocol dosage options (full vs reduced) compared to the Kenya national protocol, and of the two WHO protocol options compared to each other (full vs reduced). Enrollment will begin in early 2026, and continue for 10 months. We will also conduct an observational sub-study documenting outcomes on children with MAM but who are not considered high risk in a sub-set of study facilities. Evidence generated from the study will identify the optimal treatment strategy for better treatment performance and lower cost, providing policymakers in Kenya and across the globe with high-quality evidence to inform policy change.
