Malaria Therapeutic Efficacy Study (TES) Kenya — Kenya-TES  

Uncomplicated Malaria Clinical Trial

Official title: Efficacy of Artemether Lumefantrine (AL) and Dihydroartemisinin-Piperaquine (DHP) for the Treatment of Uncomplicated Plasmodium Falciparum Malaria in Siaya and Bungoma Counties, Kenya

Status Completed

Clinical Trial Summary

WHO recommends that Therapeutic Efficacy Studies (TES) for 1st and 2nd line antimalarial medicines should be routinely carried out and data made available for decision-making due to the threat of emergence and spread of artemisinin resistance in malaria-endemic countries, especially in Africa. In line with this WHO recommendation, Kenya Ministry of Health (MOH) is conducting the TES to determine the efficacy of artemether lumefantrine (AL), and dihydroartemisinin-piperaquine (DHP), the first and second line treatment of uncomplicated malaria in Kenya. The objective of this study is to inform the decisions or actions made by a public health authority (Kenya Ministry of Health) to inform decision on revision of the antimalarial guidelines and policy in Kenya. Jhpiego's Impact Malaria project in Kenya, with funding and technical oversight from US President's Malaria Initiative (PMI) through USAID and CDC, will support the Kenya MOH in its effort to evaluate the efficacy of AL and DHP in the treatment of children with uncomplicated malaria. The study is being conducted by Kenya MOH, with technical support and funding by PMI-USAID through Jhpiego in Kenya.

Clinical Trial Description

WHO recommends that Therapeutic Efficacy Studies (TES) for 1st and 2nd line antimalarial medicines should be routinely carried out and data made available for decision-making due to the threat of emergence and spread of artemisinin resistance in malaria-endemic countries, especially in Africa. In its strategy to strengthen malaria surveillance, Kenya's Ministry of Health (MOH) National Malaria Program (NMP) planned to conduct TES every three years to ascertain continuing efficacy of the first and second-line treatments. The last TES for 1st line treatment of malaria in Kenya was done in Siaya county in 2016. In line with the WHO recommendation, Jhpiego Impact Malaria project in Kenya, with funding and technical oversight from Center for Disease Prevention and Control (CDC) will be supporting the Kenya MOH NMP to conduct a TES to assess the efficacy of the current first and second line treatment policy in Kenya. The study is being conducted by Kenya MOH NMP, with technical oversight and funding by CDC through the Jhpiego Impact Malaria project in Kenya. Objective: To assess the efficacy of Artemether Lumefantrine (AL) and Dihydroartemisinin-Piperaquine (DHP) for the treatment of uncomplicated P. falciparum malaria infections. Study Sites: One site will be selected in Siaya county and one site will be selected in Bungoma county (Kimilili Sub-County). Both sites will be Level-2 facilities (health centers) with high outpatient department attendance of patients with malaria. At each site, there will be two study arms: one arm for AL and one arm for DHP. Study Period: March 2021 to September 2021 Study Design: This surveillance study is a two-arm prospective study Patient population: Febrile patients aged between 6 months and 59 months, with confirmed uncomplicated P. falciparum monoinfection. Sample Size: At each site, at least 100 patients will be enrolled per drug (200 patients per site, 400 patients total). Treatment(s) and follow-up: Clinical and parasitological parameters will be monitored over a 28-day follow-up period to evaluate AL efficacy, and over a 42-day follow-up period to evaluate DHP efficacy. Primary endpoints: The proportion of patients with early treatment failure, late clinical failure, late parasitological failure or an adequate clinical and parasitological response as indicators of efficacy. Recrudescence will be distinguished from re-infection by polymerase chain reaction (PCR) analysis. Secondary endpoints: The frequency and nature of adverse events. Exploratory endpoints: to determine the polymorphism of molecular markers of drug resistance and evasion of diagnostic testing; to determine the blood concentration of AL ;
