Trial of Artesunate Combination Therapy in Pakistan
This study is an evaluation of the benefit of adding artesunate to existing first and second line antimalarial therapies in Pakistan.
A placebo controlled trial was carried out to assess two potential benefits of Artesunate Combination Therapy (ACT): efficacy and potential for transmission reduction.

A randomised, double-blind placebo controlled study of the efficacy of chloroquine or sulphadoxine-pyrimethamine alone and in combination with primaquine or artesunate for the treatment of uncomplicated falciparum malaria.
- CQ+ artesunate
Patients were allocated to treatment groups using a pseudo-randomised table split by age and sex.
- Clinical and parasitological cure/treatment failure by day 28.
- time to resolution of fever
- time to clearance of trophozoites
- time to clearance of gametocytes
- gametocyte carriage on or after day 7 after treatment
All clinical assessments and slide readings were carried out by staff blind to treatment arm. Slides were double read.
