E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of a 3-day regimen of artemether-lumefantrine dispersible in infants <5 kg of BW with acute uncomplicated P. falciparum malaria using the polymerase chain reaction (PCR)-corrected 28-day parasitological cure rate. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of a 3-day regimen of artemether-lumefantrine dispersible tablet in infants <5 kg of BW with acute uncomplicated P. falciparum malaria by other parameters as specified in section E.5.2.
To evaluate the safety of a 3-day regimen of artemether-lumefantrine dispersible tablet in infants <5 kg of BW with acute uncomplicated P. falciparum malaria, with respect to the incidence of serious adverse events (SAEs), adverse events (AEs) and routine safety laboratory assessments.
To investigate the PK of artemether-lumefantrine during and following treatment with a 3-day regimen of artemether-lumefantrine dispersible tablet in infants <5 kg of BW with acute uncomplicated P. falciparum malaria. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy variable is the PCR-corrected 28-day parasitological cure rate, defined as the proportion of patients with clearance of asexual parasites within 7 days of initiating study treatment without recrudescence at Day 28, corrected for re-infection by PCR assay.
Parasitaemia results will be taken from the central microscopy reading. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy variables are:
• PCR-corrected parasitological cure rate at Day 14 and Day 42 (based on central microscopy reading)
• Parasitological uncorrected cure rate at Day 3, Day 7, Day 14, Day 28, and Day 42 (based on central microscopy reading)
• Percent parasite reduction at 24 hours after treatment initiation (based on central microscopy reading)
• Number of patients with parasitaemia at 72 hours after treatment initiation greater than or equal to 25 percent of count at baseline (based on central microscopy reading)
• Number of patients with parasitaemia at 48 hours after treatment initiation greater than at baseline (based on central microscopy reading)
• Time to parasite clearance (PCT), defined as time from first dose until first total and
continued disappearance of asexual parasite forms which remains at least a further 48 hours (based on central microscopy reading)
• Time to fever clearance (FCT), defined as time from first dose until the first time the axillary body temperature decreased below and remained below 37.5° C for at least a further 48 hours
• Time to gametocyte clearance (GCT), defined as time from first dose until first total and continued disappearance of gametocytes which remains at least a further 48 hours (based
on central microscopy reading)
• Gametocyte carriage over time (based on central microscopy reading)
Safety endpoints are
• Incidence of serious adverse events
• Incidence of adverse events
• Routine safety laboratory assessments |
