Efficacy and safety of artemether-lumefantrine for the treatment of uncomplicated Plasmodium falciparum malaria in two sites in Yemen.

Phase 4
Completed
Conditions
Malaria
Infection - Studies of infection and infectious agents
Registration Number
ACTRN12617000283370
Lead Sponsor
Ministry of Public Health and Population
Brief Summary

A total of 110 patients were recruited, six were lost to follow-up. The remaining 104 cleared parasites by day 3 and achieved adequate clinical and parasitological response on day 28. None of the samples of the study patients carried K13 mutation, marker of artemisinin resistanace.

Primary Outcome Measures
NameTimeMethod
Percent of treatment failures (early treatment failure + late clinical failure +late parasitological failure). This is a composite primary outcome.<br><br>Enrolled patients will be assessed for parasitological (using microscopy) and clinical responses and treatment outcomes will be classified according to the latest WHO protocol. [At days 1, 2, 3, 7, 14, 21, 28 ]
Secondary Outcome Measures
NameTimeMethod
Percent of adverse event following treatment.<br>Atemether+lumefantrine are abdominal pain, asthenia, cough, diarrhoea, dizziness, fever, headache, joint and muscle pain, loss of appetite, rush, nausea, vomiting.<br><br>Parents or guardians of all enrolled children will be asked routinely about previous symptoms and about symptoms that have emerged since the previous follow-up visit. When clinically indicated, patients will be evaluated and treated appropriately. All adverse events will be recorded on the case report form. [At days 1, 2, 3, 7, 14, 21, 28 ];Prevalence of artemisinin resistance molecular markers (K13).<br><br>Parasite DNA extracted from the dried blood spots will be analyzed by PCR and sequencing for the presence of K13 (molecular marker for artemisinin resistance). [At day 0 (prior to initiation of the treatment. ]
