Study information

Scientific title

Assessment of efficacy, safety and population-pharmacokinetics of the fixed-dose combination of artesunate-mefloquine in the treatment of acute uncomplicated Plasmodium falciparum malaria in India


Study hypothesis

1. To evaluate the clinical and parasitological efficacy of artesunate-mefloquine fixed-dose combination in adult patients with uncomplicated falciparum malaria, by determining the proportion of patients achieving a negative parasitaemia without recrudescence by 63 days (cure rate)
2. To measure the parasite reduction ratio at 48 hours of treatment, parasite clearance time, fever clearance time, gametocyte carriage
3. To evaluate cure rate at 28 days
4. To evaluate the population-pharmacokinetics of artesunate-mefloquine in adult patients in India
5. To evaluate the incidence of adverse events
6. To collect information to enable the Ministry of Health to make informed decisions about the possible need for updating of the current national anti-malarial treatment guidelines

All patients recruited into the study will be given full, supervised treatment with oral artesunate-mefloquine 100 mg and 220 mg tablets (two tablets daily for three days). Total duration of treatment and follow-up is 3 days of treatment and 60 days of follow-up.

Intervention type



Phase III

Drug names

Artesunate, mefloquine

Primary outcome measure

Cure rate as determined by polymerase chain reaction (PCR)-corrected adequate clinical and parasitological response (ACPR) on day 63. Treatment success or failures will be classified according to WHO Guidelines 2005.

Secondary outcome measures

1. Pharmacokinetic parameters: population pharmacokinetic parameters for artesunate (AS), dihidroartemisinin (DHA), and mefloquine (MQ)
2. Parasite reduction ratio (PRR) at 48 hours: baseline parasite count/parasite count at 48 hours
3. Parasite clearance time (PCT): time in hours from the initiation of therapy until the first of two successive (within an interval of 8 to 24 hours) parasite negative smears are obtained
4. Fever clearance time (FCT): time in hours from the initiation of therapy until disappearance of fever for at least 24 hours
5. Gametocyte carriage: percentage of patients without gametocytes at day 28
6. Proportion of patients with early treatment failure, late treatment failure, and late parasitological failure
7. Proportion of patients with mixed infections in the follow-up assessments
8. Proportion of patients with development of symptoms of severe malaria
