Brief summary

This study is a one-arm prospective evaluation of clinical and parasitological responses to directly observed treatment for uncomplicated malaria. People with uncomplicated malaria who meet the study inclusion criteria will be enrolled, treated on site with drug combination DHA-PIP, and monitored for 42 days. The follow-up will consist of a fixed schedule of check-up visits and corresponding clinical and laboratory examinations. On the basis of the results of these assessments, the patients will be classified as having therapeutic failure (early or late) or as having an adequate clinical and parasitological response. The proportion of patients experiencing therapeutic failure during the follow-up period will be used to estimate the efficacy of the study drug. PCR analysis will be used to distinguish between a true recrudescence due to treatment failure and episodes of reinfection.

Interventions

Oral tablets of drug contains DHA 40mg – PIP 320 mg will be administered at a dose of expressed as milligram base per kilogram body weight, one daily doses per day for three days. 5kg-9kg = 1/2 tablet once daily for 3 days 10kg- 19kg = 1 tablet once daily for 3 days 20kg-29kg = 1,1/2 tablet once daily for 3 days 30 kg - 39 kg = 2 tablets once daily for 3 days 40 kg- > 60kg = 3 tablets once daily for 3 days All doses of medicine will be administered under the supervision of a qualified member
