A Phase 4 interventional study of AL (Coartem) and AS-AQ (Carsucam) in Malaria, sponsored by Centro de Investigacao em Saude de Manhica. Completed at 5 sites in Mozambique. Open to participants aged 6 Months to 59 Months. Per ClinicalTrials.gov, last updated 2025-08-27.

This is a classical in vivo clinical trial, following World Health organization's recommendations, ran as a multisite study within Mozambique trying to assess the efficacy and safety in 5 sites of the four oral ACTS artemether-lumefantrine (AL), Amodiaquine-Artesunate (AQ-AS), Dihydroartemisinin-Piperaquine (DHP) and Pironaridine-Artesunate for the treatment of uncomplicated malaria in children aged\<5 years.
Eligible patients were consecutively assigned to the cohort and treated with AL (cohort 1), AQ-AS (cohort 2), DHP (cohort 3) and PA (cohort 4). AL (Coartem™) will be administered twice daily for three days (six doses in total) with dosage determined according to body weight: one tablet (20mg artemether and 120mg lumefantrine) for children 5 to \<15kg, two tablets per dose for those 15 to \<25kg, and three tablets per dose for those 25 to \<35kg. AQ-AS (Winthrop™) will be administered once daily according to body weight: one 25mg artesunate and 67.5mg amodiaquine tablet in children \<9kg, one 50mg artesunate and 135mg amodiaquine tablet in children 9-17.9kg; and one 100mg artesunate and 270mg amodiaquine tablet in children >18-35kg. DHP will be administered once daily according to body weight: half tablet (40mg dihydroartemisinin e 320 mg piperaquine) for children 5 to \< 10Kg, one tablet for per dose for those 10 \< 20Kg and 2 tablets for 20 or more Kg. PA (granules 60mg pirinaridine +/20mg artesunate) will administered once daily according to body weight: 1 granule per dose for children 5 to \< 8Kg, two for children 8 \< 15Kg, three for those 15 \< 20Kg. PA (180mg pyrinaridine+60 mg artesunate) one tablet for children 20 \< 24Kg and two tablets for those 24 \< 45Kg. All treatments will be directly observed for a minimum of 30 minutes. Vomiting occurring within the first 30 minutes implied the repetition of the full dose of treatment. For those patients living far away from the health facilities, and for which direct observation of the evening doses of AL was challenging, admission was offered for the first three days of the study.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Eligible patients will be consecutively assigned to the four cohorts. Rescue therapy according to national malaria treatment guidelines will be also administered in cases of early or late treatment failure. Follow-up visits will take place on days 1, 2, 3, 7, 14,21 and 28 after enrolment or at any time point whenever the child is sick. Adverse events will be recorded and assessed for severity and association with study medication. Thick and thin Giemsa-stained blood slides will be prepared before each dose to be administered and at every follow-up visit of days 2, 3, 7, 14, 21, 28, 35 and 42. Blood samples for PCR analysis will be collected from every patient at baseline and at days 7, 14, 28, and 42 day of treatment failure or at any other unscheduled visit. The Molecular markers associated with suboptimal response to ACTs will be investigated.

To measure the Day 28, PCR corrected cure rates of artemether-lumefantrine and Amodiaquine-artesunate.
This cure rate is defined as the proportion of patients with adequate clinical and parasitological response (ACPR) at Day 28, once PCR correction to differentiate recrudescences from new infections have been applied (and hence only considering as treatment failures those parasite recurrences confirmed as recrudescences).
Time frame: 28 days
To measure the Day 42, PCR corrected cure rates of Dihydroartemisinin-Piperaquine and Pironaridine-Artesunate
This cure rate is defined as the proportion of patients with adequate clinical and parasitological response (ACPR) at Day 42, once PCR correction to differentiate recrudescences from new infections have been applied (and hence only considering as treatment failures those parasite recurrences confirmed as recrudescences).
Time frame: 42 days
To evaluate the incidence of adverse events
Safety was assessed by administering a questionnaire about the nature and incidence of adverse events and serious adverse events. An adverse event is defined as any unfavorable, unintended sign, symptom, syndrome or disease that develops or worsens with the use of a medicinal product, regardless of whether it is related to the medicinal product.
Time frame: 28/42 days
To measure the Day PCR uncorrected cure rates of Artemether-Lumefantrine, Amodiaquine-Artesunate, Dihydroartemisinin-Piperaquine, and Pironaridine-Artesunate.
This cure rate is defined as the proportion of patients with adequate clinical and parasitological response (ACPR) at Day 28/42, without PCR correction to differentiate recrudescences from new infections and hence considering as treatment failures all parasite recurrences.
Time frame: 28/42 days
Evaluate the presence of Molecular Markers associated with sub optimum responses to ACTs
The presence of molecular marks is defined as presence of mutations in pfk13 and pfmdr1 (at codons 86, 184 and 1246) genes identified by Sanger sequencing of pre-treatment samples.
Time frame: 28/42 days
