Molecular Surveillance of Artemisinin Resistance Malaria in Myanmar

Completed
Conditions
Drug Resistance
Plasmodium Falciparum Malaria
Interventions
Drug: First line antimalarial in Myanmar (artemether-lumefrantrine, dihydroartemisinin-piperaquine, and artesunate-mefloquine)
Registration Number
NCT02792816
Lead Sponsor
Department of Medical Research, Lower Myanmar
Brief Summary

Efficacy and safety of the artemisinin combination therapy (ACT) in uncomplicated falciparum malaria patients in Myanmar and artemisinin molecular markers analysis

Detailed Description

The investigators assessed the efficacy and safety of the ACT in uncomplicated falciparum malaria in different sentinel sites in Myanmar. The recruited patients were follow-up until day 28 or day-42 based on the ACTs. Day-0 samples were analysed for artemisinin molecular markers, (K13 kelch propeller, Pfmdr2, Pffd and Pfarps10).

Myawaddy SiteFirst line antimalarial in Myanmar (artemether-lumefrantrine, dihydroartemisinin-piperaquine, and artesunate-mefloquine)The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Myawaddy is one of the sentinel site and located at the northern part of the Southern Myanmar.
Kawthaung SiteFirst line antimalarial in Myanmar (artemether-lumefrantrine, dihydroartemisinin-piperaquine, and artesunate-mefloquine)The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Kawthaung is one of the sentinel site and located at the Southern Myanmar.
Thanbyuzayat SiteFirst line antimalarial in Myanmar (artemether-lumefrantrine, dihydroartemisinin-piperaquine, and artesunate-mefloquine)The efficacy and safety of the ACT in different sentinel sites will be assessed.

Thanbyuzayat is one of the sentinel site and located at the northern part of the Southern Myanmar.
Shwegyin SiteFirst line antimalarial in Myanmar (artemether-lumefrantrine, dihydroartemisinin-piperaquine, and artesunate-mefloquine)The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Shwegyin is one of the sentinel site and located at the southern part of the central Myanmar.
Magway SiteFirst line antimalarial in Myanmar (artemether-lumefrantrine, dihydroartemisinin-piperaquine, and artesunate-mefloquine)The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Magway is one of the sentinel site and located at the middle part of the central Myanmar.
Rakhine SiteFirst line antimalarial in Myanmar (artemether-lumefrantrine, dihydroartemisinin-piperaquine, and artesunate-mefloquine)The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Rakhine is one of the sentinel site and located at the western Myanmar.
Primary Outcome Measures
NameTimeMethod
Proportion of adequate clinical and parasitological response (ACPR)day 28 or day 42 after initial dose of ACT

For artesunate-mefloquine or dihydroartemisinin-piperaquine, 42 days follow-ups and for artemether-lumefrantrine combinations, 28 days followe-ups

Secondary Outcome Measures
NameTimeMethod
Proportion of the day-3 parasite positivity after ACT by microscopy3rd day after initial dose of ACT

72 hr after ACT is one of the indicator for delayed clearance of parasitaemia in falciparum malaria

Treatment failure rateanytime within observation period (28/42 days after treatment with one of ACTs)

Early Treatment Failure (ETF), Late Clinical Failure (LCF), Late Parasitological Failure (LPF) based on the WHO standard protocol and definitions

Mutant rateDay-0 samples

Day-0 samples were used to amplify the artemisinin resistance molecular markers to know the mutant rate in each study sites
