Condition oral treatment of acute uncomplicated plasmodium falciparum malaria
Treatment fosmidomycin-piperaquine
Phase phase 2
Sponsor Jomaa Pharma GmbH
Collaborator Centre de Recherches Medicales de Lambarene (CERMEL)
Start date March 2014
End date July 2014
Trial size 100 participants
Trial identifier NCT02198807, JP017


The objective of this study is to explore the role of fosmidomycin and piperaquine as non-artemisinin-based combination therapy for acute uncomplicated Plasmodium falciparum when administered over three days.

Together, fosmidomycin and piperaquine fulfil the WHO criteria for combination therapy by meeting the three key parameters of having different modes of action and different biochemical targets while exhibiting independent blood schizonticidal activity. Like the artemisinins, fosmidomycin is fast-acting, has an excellent safety record and is active against existing drug-resistant parasites. Piperaquine has a long half life protecting fosmidomycin as a much shorter lived molecule against selection of resistant parasites and will provide post-treatment prophylaxis.
