Clinical Trial Summary

This study aims to explore whether SMC is an effective intervention in the context of Northen Bahr el Gazal state, South Sudan. It also aims to assess the protective efficacy of the antimalarials used in SMC in the target population and investigate levels of parasite resistance in the study counties. If successful, this trial should provide the evidence for SMC to be included in malaria programming and policy in South Sudan. A Type II hybrid effectiveness-implementation study design will be used to evaluate the effects of a clinical intervention on relevant outcomes whilst collecting information on implementation. It is designed to determine feasibility and effectiveness of an innovative intervention, as well as the protective efficacy of the antimalarial drugs used. The study consists of five components: 1) A series of cross-sectional surveys establishing confirmed malaria cases in children; 2) A prospective cohort study to determine the protective efficacy of SPAQ (if SPAQ provides 28 days of protection from infection) and whether drug concentrations and/or resistance influence the duration of protection; 3) A resistance markers study in children 3-59 months in the research county; 4) Modelling the protective effect of SPAQ in South Sudan to determine where SMC could be a suitable malaria prevention strategy in other areas of the country, and 5) A process evaluation to understand feasibility and acceptability of the SMC intervention in South Sudan.


Clinical Trial Description

This is an implementation research study, using a Type II hybrid effectiveness-implementation study design, to evaluate the effects of a clinical intervention on relevant outcomes whilst collecting information on implementation. The study uses pragmatic implementation research with the objective of contributing to the development of practical recommendations for health policy, practice and potential scale up. It is designed as an implementation study to determine effectiveness and protective efficacy to gather evidence of its potential impact on health outcomes. Five monthly cycles of SMC will be implemented between June and October 2022 in one county, Aweil South, in Northern Bahr el Gazal state. The study will comprise the following six components : 1. Two cross-sectional surveys at the height of the malaria season to explore impact on malaria incidence 2. End-of-round survey 3. Prospective protective efficacy cohort study to determine if SPAQ provides 28 days of protection from infection and whether drug concentrations and/or resistance influence the duration of protection 4. Resistance markers study in children 3-59 months in the two research counties plus the two standard intervention counties to measure changes in resistance marker prevalence over time (pre and post within the same year and between years) ;
