Clinical Trial Summary

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.


Description:

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.

Arms:

1. CQ

2. CQ+primaquine

3. CQ+ artesunate

4. SP

5. SP+primaquine

6. SP+artesunate

Patients were allocated to treatment groups using a pseudo-randomised table split by age and sex.

Primary outcomes:

- Clinical and parasitological cure/treatment failure by day 28.

Secondary outcomes:

- 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.
