Detailed Description
Brief title: Efficacy and safety of artesunate-amodiaquine and artemether-lumefantrine for the treatment of malaria in Cameroon.
Official title: Monitoring the efficacy and safety of artesunate-amodiaquine and artemether-lumefantrine for the treatment of uncomplicated Plasmodium falciparum malaria among children in the Center Region of Cameroon.
Purpose: To monitor the efficacy and safety of artesunate-amodiaquine and artemether-lumefantrine for the treatment of uncomplicated Plasmodium falciparum malaria among children in the Center Region of Cameroon.
Background: Malaria remains a major public health concern in Cameroon especially among vulnerable groups such as children less than 5 years and pregnant women. artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) are currently being used for the treatment of uncomplicated Plasmodium falciparum in Cameroon. 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.
Objective: To assess the efficacy and safety of artesunate-amodiaquine and artemether-lumefantrine during a 28-day follow-up period among children with acute uncomplicated P. falciparum malaria in Center Region of Cameroon.
Study sites: District Hospital Akonolinga, District Hospital Mfou, District Hospital Soa, District Hospital Mbalmayo, District Hospital Mbandjock, and District Hospital Ngog-Mapubi in the Center Region of Cameroon.
Study period: 5th April to 31st December, 2021. Study design: This surveillance study is a two arm, open label, randomized controlled clinical trial.
Patient population: 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.
Sample size: 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. At least 30 participants shall be enrolled at each of the six study sites.
Treatment (s) and follow-up: 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.
Classification of treatment outcomes: Classification of treatment outcomes will be done based on the WHO 2009 guidelines: treatment failure (Early Treatment Failure-ETF, Late Clinical failure-LCF and Late Parasitological Failure-LPF) and treatment success (Adequate Clinical and Parasitological Response-ACPR).

Description
Inclusion Criteria:
- Children of either gender, aged 6 months to 10 years will be recruited.
- Uncomplicated P. falciparum malaria confirmed by microscopy using Giemsa-stained thick film with an asexual parasite density within the range 1000 to 200000 parasites/μl.

- Willing and able to attend the clinic on stipulated regular follow-up visits.
Exclusion Criteria:
- Mixed or mono-infection with another Plasmodium species detected by microscopy.
- Children who are currently suffering or had the following within the last 2 months: tuberculosis, HIV, schistosomiasis, diabetes mellitus, cardiovascular disease, gout, rheumatoid arthritis, underlying chronic hepatic or renal disease, hypoglycaemia, jaundice, respiratory distress, and other inflammatory-related diseases.
Signs/symptoms indicating severe/complicated malaria" according to WHO criteria (WHO definition) such as:
