Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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 of staff designated by the principal investigator.

Outcomes
Primary outcome [1] 307516 0
The proportion of treatment success confirmed by using blood smears for microscopy and dry blood spot for Polymerase Chain-Reaction (PCR). For the purposes of this study, treatment success is defined as patients who have an adequate clinical and parasitological response to treatment.
Timepoint [1] 307516 0
42 days after treatment the primary timepoint patients will be assessed daily on Day0,1,2 and 3 and weekly thereafter ( D7,D14,D21,D28,D35) until Day 42
Secondary outcome [1] 352158 0
Evaluate safety by the incidence of adverse events assessed by clinical observation of symptoms. For example: vomiting, abdominal pain, and rashes
Timepoint [1] 352158 0
Any time adverse events occur between Day 0 and Day 7

- Presence of axillary temperature more than 37.5 °C or history of fever during the past 24 h;
- Ability to swallow oral medication;
- Ability and willingness to comply with the study protocol for the duration of the study and to comply with the study visit schedule;
- Informed consent from the patient or from a parent or guardian in the case of children aged less than 12 year old;

Key exclusion criteria
- presence of general danger signs in children aged under 5 months or signs of severe falciparum malaria according to the definitions of WHO
- weight under 5 kg;
- mixed or mono-infection with another Plasmodium species detected by microscopy;
- presence of severe malnutrition (defined as a child whose growth standard is below –3 z-score, has symmetrical oedema involving at least the feet or has a mid-upper arm circumference < 115 mm);
- presence of febrile conditions due to diseases other than malaria (e.g. measles, acute lower respiratory tract infection, severe diarrhea with dehydration) or other known underlying chronic or severe diseases (e.g. cardiac, renal and hepatic diseases, HIV/AIDS);

- history of hypersensitivity reactions or contraindications to any of the medicine(s) being tested or used as alternative treatment(s);
- Female patients of child-bearing age, defined as those who menstruate and who are sexually active, will be not included in the study, because they are always not honest to tell on their sexual intercourse experience, which also reflects local culture if they are not yet married.

Statistical methods / analysis
As the treatment failure rate to the DHA-PIP in the area is unknown, 5% has been chosen. At a confidence level of 95% and a precision around the estimate of 5%, a minimum of 50 patients must be included. With a 20% increase to allow loss to follow-up and withdrawals during the 42-day follow-up period, 100 patients should be included in the study for p.falciparum.

Summary
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.
