Written informed consent must be obtained before any study assessment is performed. If the patient is unable to write, then a witnessed consent according to local ethical standards is permitted. KEY Exclusion Criteria: 1. Mixed Plasmodium infections. 2. Signs and symptoms of severe malaria according to World Health Organization (WHO) 2016 criteria (WHO 2016). 3. Known liver abnormalities, liver cirrhosis (compensated or decompensated), known active or history of hepatitis B or C (testing not required), known gallbladder or bile duct disease, acute or chronic pancreatitis. 4. Clinical or laboratory evidence of any of the following: 5. AST/ALT > 1.5 x the upper limit of normal range (ULN), regardless of the level of total bilirubin 6. AST/ALT > 1.0 and = 1.5 x ULN and total bilirubin is > ULN 7. Total bilirubin > 2 x ULN, regardless of the level of AST/ALT 8. History of photodermatitis/increased sensitivity to sun. 9. Pregnant or nursing (lactating) women. 10. Known disturbances of electrolyte balance, e.g. hypokalemia, hypocalcemia or hypomagnesemia. 11. Moderate to severe anemia (Hemoglobin level <8 g/dL).

Outcome

Type Measure Description Time frame Safety issue
Primary Number of Participants With at Least 2 CTCAE Grades Increase From Baseline in Alanine Aminotransferase (ALT) or Aspartate Aminotransferase (AST) The occurrence of at least 2 CTCAE grades increase from baseline in ALT or AST during the 4 weeks study period was evaluated to characterize hepatic safety aspects of single and multiple ascending doses of KAE609 in adult malaria subjects for treatment of uncomplicated malaria caused by plasmodium falciparum. If 2 patients in a 10 patient cohort (Cohorts 1 and 2) or 3 patients in a 20 patient cohort (Cohorts 3, 4 and 5) had at least 2 CTCAE grades increase from Baseline in ALT or AST, recruitment was suspended and a review of liver safety (and any other relevant data) by safety review committee was initiated. Any further progression of the study was based on the decision by the safety review committee. Day 29
Secondary Percentage of Participants With Polymerase Chain Reaction (PCR)-Corrected and Uncorrected Adequate Clinical and Parasitological Response (ACPR) at Day 15 and Day 29 PCR-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. Day 15, Day 29
Secondary Parasite Clearance Time (PCT) Parasite 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. Day 29
Secondary Fever Clearance Time (FCT) Fever 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. Day 29
Secondary 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. Day 29
Secondary Maximum Peak Observed Concentration (Cmax) Maximum Peak Observed Concentration (Cmax) Day 1, Day 3
Secondary Tmax Tmax Day 1, Day 3
Secondary AUC0-24 AUC0-24 Day 1, Day 3
Secondary Half-life (T^1/2) Half-life (T^1/2) Upto day 15 post dose
