Condition(s) targeted: Oral Treatment of Acute Uncomplicated Plasmodium Falciparum Malaria

Intervention: Fosmidomycin-Piperaquine (Drug)

Phase: Phase 2

Status: Active, not recruiting

Sponsored by: Jomaa Pharma GmbH

Summary

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.
