Dose Ranging Study of Ferroquine With Artesunate in African Adults and Children With Uncomplicated Plasmodium Falciparum Malaria
- Conditions
- Plasmodium Falciparum Infection
- Interventions
- Registration Number
- NCT00988507
- Lead Sponsor
- Sanofi
- Brief Summary
Primary objective: To assess the Day 28 efficacy defined as the percentage of patients with no parasitic recrudescence, of 3 treatment groups - 3 dose levels of ferroquine associated with artesunate - for a 3-day treatment.
Secondary objectives:
* To assess the efficacy of ferroquine at one dose level alone for a 3-day treatment.
* To assess the clinical safety of 4 treatment groups - 3 dose levels of ferroquine associated with artesunate and one dose level of ferroquine alone.
* To assess pharmacokinetics parameters of ferroquine and its metabolites along sparse sampling schedules.
- Detailed Description
The overall study duration is 64 days, consisting of a screening period (less or equal 1 day), of a 3-day treatment period during which the patient is hospitalized for a maximum of 60 hours, and a follow-up period of 61 days.

The need for an efficient method will be reminded to the patient and the patient's legal guardian(s) by the investigator.
