Study type
Interventional
Description of intervention(s) / exposure
The efficacy and safety of 3 drugs used by the control program as anti-malarial standard treatment, artesunate, DHA-PIP and CQ, will be assessed separately in 9 different groups of patients in 5 different study sites. Pf malaria patients in Binh Phuoc and Ninh Thuan sites will receive Artesunate for 7 days in 2008 and in Quang Tri site in 2009. Pf malaria patients in Quang Tri, Gia Lai sites will receive DHA-PIP for 3 days in 2008 and in Binh Phuoc, Dak Nong sites in 2009. Pv malaria patients in Ninh Thuan and Binh phuoc will receive CQ for 3 days in 2009.
- Oral artesunate (50 mg/tab) will be administered at a total dose of 16 mg/kgbw over 7 days (1st day: 4 mg/kgbw, 2nd to 7th days: 2 mg/kgbw/day).
- Oral dihydroartemisinin-piperaquine(DHA-PIP) will be administered at a dose of 2mg/kg/day DHA and 16mg/kg/day PIP for 3 days.
- Oral chloroquine will be administered at a total dose of 25mg/kgbw (10 mg/kgbw on day0, 10mg/kgbw on day1 and 5 mg/kgbw on day2).
The WHO 28 day in vivo protocol, used in this study, consists of parasite count and temperature measurements at baseline (day0 before dosing) and on days 1, 2, 3, 7, 14, 21 and 28.
