Efficacy, Safety and Tolerability of KAF156 in Combination With Lumefantrine Solid Dispersion Formulation (LUM-SDF) in Pediatric Population With Uncomplicated Plasmodium Falciparum Malaria (KALUMI)
A Phase 2 Interventional, Multicenter, Randomized, Open-label Study in Three Age-descending Cohorts to Evaluate Efficacy, Safety and Tolerability of KAF156 and Lumefantrine-SDF Combination in the Treatment of Acute Uncomplicated Plasmodium Falciparum Malaria in a Pediatric Population

Detailed Description
This Phase 2 study aims to evaluate the efficacy, safety and tolerability of the investigational drug KAF156 and a Solid Dispersion Formulation of lumefantrine (LUM-SDF) when administered in combination in pediatric patients 6 months to < 18 years of age with uncomplicated Plasmodium falciparum malaria. In addition, pharmacokinetics (PK) of the drug combination will also be evaluated.
There will be three age-descending cohorts: Run-in Cohort, Cohort 1 and Cohort 2.
It is important to understand the impact of food on exposure. In adult healthy volunteers, LUM-SDF alone has shown a food effect whereas KAF156 does not have a food effect. This new study will first explore the effect of food on lumefantrine and KAF156 PK in malaria patients 12 to < 18 years old with malaria caused by P. falciparum before younger patients are assessed.
Then, efficacy, safety and tolerability of the combination of KAF156 and LUM-SDF will be evaluated in younger patients, first in Cohort 1 of patients 2 to < 12 years old and then in Cohort 2 of patients 6 months to < 2 years old.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
PCR-corrected adequate clinical and parasitological response (ACPR) at Day 29 (i.e., 28 days post-dose) (Cohorts 1 and 2 pooled).
Time Frame: Day 29
|
The primary efficacy variable is the PCR corrected Adequate Clinical and Parasitological Response (ACPR) at Day 29 (Cohorts 1 and 2 pooled).
In case that Cohort 2 stops early, such as after the first 24 patients, the study objectives will be assessed based on Cohort 1 data alone.
A patient is considered as PCR corrected ACPR at Day 29 if the patient does not meet any of the criteria of early treatment failure (ETF) (up to Day 4), late clinical failure (LCF) (Day 5 to Day 29) or late parasitological failure (LPF) (Day 8 to Day 29), and is absence of parasitaemia on Day 29 irrespective of axillary temperature unless the presence of parasitaemia after 7 days (Day 8 or later) is due to reinfection based on PCR genotyping.
A presence of parasitaemia after 7 days of treatment initiation is considered as a reinfection only if the parasitaemia is clear before Day 8 and none of the parasite strain(s) detected on Day 8 or later match with the parasite strain at baseline based on PCR genotyping.

Time to event (recrudescence or reinfection) will be calculated from the time of first study medication to the date of first event if a patient experiences the event and be censored at the time of last parasite assessment if a patient does not experience the event due to whatever reason. Reinfection is defined as appearance of asexual parasites after clearance of initial infection with a genotype different from those parasites present at baseline. Recrudescence is defined as appearance of asexual parasites after clearance of initial infection with a genotype identical to that of parasites present at baseline.
