MeasureTime frameDescription
Parasite Clearance Time (PCT)Day 29Parasite Clearance Time (PCT) is defined as the time from the first dose until the first total and continued disappearance of asexual parasite forms which remained at least a further 48 hours. In case a patient received rescue medication before (parasite) clearance, the time to event was censored at the first use of rescue medication.
Fever Clearance Time (FCT)Day 29Fever Clearance Time (FCT) is defined as the time from the first dose until the first time the axillary body temperature decreased below and remained below 37.5°C axillary or 38.0°C oral/tympanic/rectal for at least a further 24 hours. In case a patient received rescue medication before (fever) clearance, the time to event was censored at the first use of rescue medication.
Time to Recrudescence and Reinfection at Study Day 29Day 29Time to recrudescence is calculated from the date of first study medication to the date of first event. Participants without recrudescence/reinfection after Day 7 are censored at the time of treatment failure or at the time of last parasite assessment if no treatment failure occured.
Percentage of Participants With Polymerase Chain Reaction (PCR)-Corrected and Uncorrected Adequate Clinical and Parasitological Response (ACPR) at Day 15 and Day 29Day 15, Day 29PCR-corrected and PCR-uncorrected were evaluated at Days 15 and 29 (i.e., 14 and 28 days post-dose). The presence of parasitaemia after 7 days due to reinfection was considered as PCR-corrected ACPR. Missing blood smear data at Day 15 visit and thereafter were not considered as responder for the visit unless there was a later blood smear test indicating no parasitaemia.

Recruitment details

This study was conducted in 10 centers in 5 countries: Mali (2), Uganda (3), Ghana (2), Gabon (1), Rwanda (2).

Pre-assignment details

Approximately, 210 patients were planned to be randomized in six cohorts (KAE609: 150 and Coartem: 60). A total of 188 (KAE609: 137 and Coartem: 51) subjects were randomized in five cohorts. Cohort 6 was optional and never initiated. Two of the 188 randomized subjects were not treated and therefore were excluded from all analyses.

Time to Recrudescence and Reinfection at Study Day 29

Time to recrudescence is calculated from the date of first study medication to the date of first event. Participants without recrudescence/reinfection after Day 7 are censored at the time of treatment failure or at the time of last parasite assessment if no treatment failure occured.

Time frame: Day 29

Population: Full Analysis Set (FAS). Only participants with clearance of initial infection before Day 15 and recrudescence/reinfection are included in the analysis.
