NCT ID: NCT04829695 Not yet recruiting - Falciparum Malaria Clinical Trials

Efficacy and Safety of Artesunate-amodiaquine and Artemether-lumefantrine for the Treatment of Malaria in Cameroon

Start date: April 5, 2021
Phase: Phase 4
Study type: Interventional

Malaria remains a major public health concern in Cameroon especially among vulnerable groups such as children less than five years and pregnant women. Artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) have been used for the treatment of uncomplicated Plasmodium falciparum in Cameroon since 2004. Worldwide, several studies among children have reported high efficacy and safety of artemisinin-based combination therapies (ACTs). There is paucity of data to support the continuous use of ASAQ and AL in Cameroon. The main objective of this study is to assess the efficacy and safety of artesunate-amodiaquine and artemether-lumefantrine during a 28-day follow-up period in children with acute uncomplicated P. falciparum malaria in the Center Region of Cameroon. A randomized, open-labelled, controlled clinical trial comparing artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) will be carried out from 5th April to 31st December, 2021 at six hospitals in the Center Region of Cameroon. The study participants shall include febrile patients aged 6 months to 10 years with confirmed uncomplicated P. falciparum infection. Eligible children for whom parent/guardian informed consents are obtained will be randomized to receive either artesunate-amodiaquine (group A) or artemether-lumefantrine (group B) in the ratio 1:1. A minimum sample of 76 patients will be required for the study. With a 20 % increase to allow loss to follow-up and withdrawals during the 28-day follow-up period, 92 patients will be enrolled for each of the two study arms. The study will recruit a total of 184 patients. However, since 6 sites will be involved, a minimum of 30 participants shall be enrolled per site. Drug intake will be done under strict supervision on days 0, 1 and 2. Follow-up visits will be performed on days 3, 7, 14, 21, and 28 to evaluate clinical and parasitological resolution of their malaria episode as well as adverse events. Polymerase chain reaction (PCR) genotyping of merozoite surface proteins 1 and 2 (msp-1, msp-2) as well as glutamate rich protein (GLURP) will be used to differentiate between recrudescence and new infection.

Clinical Performance of the Histidine Rich Protein 2 (HRP2) Highly Sensitive Rapid Diagnostic Test (HS-RDT) for Malaria Diagnosis in Pregnant Women in Papua New Guinea

Start date: April 2018
Phase: N/A
Study type: Observational

Malaria during pregnancy remains an important public health issue in endemic countries. Most cases of malaria in pregnant women are asymptomatic, and can contribute to adverse outcomes, such as maternal and neonatal anaemia as well as low birth weight. Infections that do not cause symptoms (sub-clinical infections) - particularly in low transmission settings -remain difficult to diagnose during pregnancy but can contribute to adverse outcomes e.g. growth restriction, premature birth, miscarriage and stillbirth. The Bill & Melinda Gates Foundation (BMGF) has supported the development of an HRP2-based high sensitivity rapid diagnostic tests (HS-RDT) that has analytical sensitivity ten times better than current RDTs and a sensitivity near 80% when compared to the 'gold standard' of quantitative polymerase chain reaction (qPCR). In this regard, the new HS-RDT may be a promising diagnostic and screening test for subclinical malaria during pregnancy. The overall aim is to compare the performance of novel high sensitivity rapid detection tests with conventional rapid diagnostic tests for Plasmodium falciparum malaria infection in pregnant women in Papua New Guinea

NCT ID: NCT01361269 Not yet recruiting - Malaria Clinical Trials

Evaluation of Fosmidomycin and Clindamycin in the Treatment of Acute Uncomplicated Plasmodium Falciparum Malaria

Start date: June 2011
Phase: Phase 2
Study type: Interventional

Few efficient drugs for malaria treatment are available so far. Due to increased exposure of these drugs and due to the high risk of development of drug resistant strains of Plasmodium falciparum, new drug combinations have to be actively investigated. The investigators will test the efficiency, safety and tolerance of combined fosmidomycin and clindamycin treatment in acute uncomplicated malaria in children aged 3-10 years.
