E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy of KAF156 combined with LUM-SDF compared to Coartem® (non-inferiority trial) for the treatment of uncomplicated malaria caused by P. falciparum in children 6 months to < 12 years old |
|
E.2.2 | Secondary objectives of the trial |
1) To investigate the effect of food on lumefantrine bioavailability in patients 12 to < 18 years old (Run-in Cohort). 2) To investigate the effect of food on KAF156 bioavailability in patients 12 to < 18 years old (Run-in Cohort). 3) To evaluate safety and tolerability of KAF156/LUM-SDF in pediatric patients (6 months to <18 years old). 4) To assess PK of KAF156 and lumefantrine in pediatric patients (6 months to <12 years). 5) To evaluate the efficacy of KAF156 combined with LUM-SDF by assessing uncorrected and corrected adequate clinical and parasitological response (ACPR) at different time points as well as fever- and parasite- clearance times. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• In Run-in Cohort: Male and female patients 12 to < 18 years of age, with a body weight ≥ 35.0 kg; In Cohort 1: Male and female patients 2 to < 12 years of age, with a body weight ≥ 10.0 kg; In Cohort 2: Male and female patients 6 months to < 2 years of age, with a body weight ≥ 5.0 kg • Microscopic confirmation of P. falciparum by Giemsa-stained thick and thin films • P. falciparum parasitemia of ≥ 1,000 and ≤ 150,000 parasites/μL at the time of pre-screening for Run-in Cohort • P. falciparum parasitemia of ≥ 1,500 and ≤ 150,000 parasites/μL at the time of pre-screening for Cohorts 1 and 2 • Axillary temperature ≥ 37.5 ºC or oral/tympanic/rectal temperature ≥ 38.0 ºC; or history of fever during the previous 24 hours (at least documented verbally) • Written informed consent has been obtained from parent / legal guardian before any assessment is performed. If the parent / legal guardian is unable to read and write, then a witnessed consent according to local ethical standards is permitted. Patients who are capable of providing assent, must provide assent with parental/legal guardian consent or as per local ethical guidelines • The patient and his/her parent/legal guardian is able to understand and comply with protocol requirements, instructions and protocol-stated restrictions and is likely to complete the study as planned. |
|
E.4 | Principal exclusion criteria |
• Mixed Plasmodium infections as per light microscopy results • Signs and symptoms of severe malaria according to the World Health Organization (WHO 2015) • Patients with concurrent febrile illnesses (e.g., typhoid fever, known or suspected COVID19) • Repeated vomiting (defined as more than 3 times in the 24 hours prior to inclusion in the study) or severe diarrhea (defined as more than 3 watery stools in the 24 hours prior to inclusion in the study) • Clinically relevant abnormalities of electrolyte balance which require correction, e.g., hypokalemia, hypocalcemia or hypomagnesemia • Anemia (hemoglobin level < 7 g/dL) • Patients of child bearing potential, defined as all girls post first menarche (except for Run-in Cohort) • Pregnant or nursing (lactating) patients • Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of drugs (e.g., HIV patients on ART therapy or TB patients on treatment), or which may jeopardize the patient in case of participation in the study. 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: • Aspartate aminotransferase (AST)/alanine aminotransferase (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 • 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) • 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. |
