It follows an agreement to develop a new drug between GlaxoSmithKline and the World Health Organisation (WHO).
"It could be an important development in the fight against malaria," said Fatoumata Nafo-Traore of the WHO.
The WHO estimates that there are up to 500 million malaria cases each year - the leading cause of death in children in sub-Saharan Africa.
Some of the most frequently-used treatments for malaria are becoming less effective as the parasite can become resistant.
The new fixed-dose drug will combine chlorproguanil, dapsone and artesunate and it is hoped to be ready for regulatory approval in 2006.
