The aim of this study is to evaluate the role of clindamycin and artesunate as possible combination partners for fosmidomycin to protect it from its susceptibility to recrudescent infections when used as monotherapy for acute Plasmodium falciparum malaria while retaining its excellent safety profile

Further study details as provided by Jomaa Pharma GmbH:

Primary Outcome Measures:
  • Efficacy of fosmidomycin and clindamycin/artesunate when co-administered to adults with acute uncomplicated P.f. malaria. [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • To determine the viability and infectivity of gametocytes induced by the co-administration of fosmidomycin with clindamycin or with clindamycin plus artesunate to adult subjects with acute uncomplicated Plasmodium falciparum malaria. [ Time Frame: 12 months ]

Estimated Enrollment: 40
Arms Assigned Interventions
No Intervention: single arm
Drug: Fosmidomycin
450 mg capsules, every 12 hrs for 3 days

Detailed Description:
The scientific rationale for the use of this combination is to inhibit the ability of the parasite to synthesise isoprenoids, as precursors of many essential compounds including sterols, carotenoids and ubiquinones. This is effected through blockade of the non-mevalonate pathway by fosmidomycin as a potent inhibitor of 1-deoxy-D-xylulose 5-phosphate reductoisomerase coupled with targeting of protein biosynthesis by azithromycin through binding to the 50S ribosomal subunit. This mode of action contrasts with the ability of the human host to utilise the mevalonate pathway for isoprenoid synthesis and accounts for the safety profiles of both drugs through the mechanism of selective toxicity. Moreover it affords protection against cross resistance with existing chemotherapeutic agents.
