Outcomes

Primary Outcome Measures

PCR-corrected adequate clinical and parasitological response (ACPR) at Day 29 (i.e., 28 days post-dose) (Cohorts 1 and 2 pooled).
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.

Secondary Outcome Measures

Percentage of Participants with Polymerase Chain Reaction (PCR)-corrected and uncorrected Adequate Clinical and Parasitological Response (ACPR) at Day 15 and 43
A blood draw will be performed at each collection time point for parasitemia assessment.

Proportion of patients with Late Parasitological Failure (LPF)
LPF is defined as the presence of parasitemia on any day from Day 8 to Day 43 and axillary temperature < 37.5oC without previously meeting any of the criteria of ETF or LCF
Incidence rate of recrudescence and reinfection
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. Reinfection and Recrudescence must be confirmed by PCR analysis.

5. Study Description

Brief Summary
This study aims to determine the efficacy, safety and tolerability of the investigational drug KAF156 in combination with a solid dispersion formulation of lumefantrine (LUM-SDF) in pediatric patients (6 months to < 18 years of age) with uncomplicated P. falciparum malaria. There is an unmet medical need for anti-malarial treatment with a new mechanism of action to reduce the probability of developing resistance.
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.

The investigator should make this determination in consideration of the patient's medical history and/or clinical or laboratory evidence of any of the following: AST/ALT > 3 x the upper limit of normal range (ULN), regardless of the level of total bilirubin AST/ALT > 1.5 and ≤ 2 x ULN and total bilirubin is > ULN Total bilirubin > 2 x ULN regardless of the level of AST/ALT Resting QT interval corrected by Fridericia's formula (QTcF) > 450 ms at screening Creatinine > 2 x ULN in the absence of dehydration. In case of dehydration, creatinine should be < 2 x ULN after oral/parenteral rehydration Any severe disease condition which might prohibit participation in this study Known chronic underlying disease such as sickle cell disease, and severe cardiac, renal, or hepatic impairment Known active or uncontrolled thyroid disease Inability to swallow oral medication (in tablet and/or liquid form) Patients with prior antimalarial therapy or antibiotics with antimalarial activity within minimum of their five (5) plasma half-lives (or within 4 weeks of screening if half-life is unknown) Use of other investigational drugs within 30 days of dosing or until the expected pharmacodynamic effect has returned to baseline, whichever is longer Patients taking medications prohibited by the protocol Previous participation in any malaria vaccine study or received malaria vaccine in any other circumstance within 3 months of dosing History or family history of long QT syndrome or sudden cardiac death, or any other clinical condition known to prolong the QTc interval, such as history of symptomatic cardiac arrhythmias, clinically relevant bradycardia or severe heart disease Use of agents known to prolong the QT interval unless it can be permanently discontinued for the duration of study History of hypersensitivity to any of the study drugs or its excipients or to drugs of similar chemical classes For the Run-in Cohort only: Pregnant or nursing (lactating) patients Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using basic methods of contraception during dosing of investigational drug. Basic contraception methods include: Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks before taking investigational drug. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment Male sterilization (at least 6 m prior to screening). For female patients on the study, the vasectomized male partner should be the sole partner for that patient Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps). Use of oral, (estrogen and progesterone), injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS) In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking investigational drug. Women are considered not of child bearing potential if they have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential. For Cohorts 1 and 2 only: Patients of child bearing potential, defined as all girls post first menarche (except for Run-in Cohort)
