Safety of KAE609 in Adults With Uncomplicated Plasmodium Falciparum Malaria.

A Phase 2, Multi-center, Randomized, Open-label, Dose-escalation Study to Determine Safety of Single (QD) and Multiple (3 QD) Doses of KAE609, Given to Adults With Uncomplicated Plasmodium Falciparum Malaria.

KAE609 will be evaluated primarily for hepatic safety of single and multiple doses in sequential cohorts with increasing doses.This study aims to determine the maximum safe dose of the investigational drug KAE609 in malaria patients.

3. P. falciparum parasitaemia of 500 to 50 000 parasites/µL.
4. Axillary temperature ≥ 37.5ºC or oral/tympanic/rectal temperature ≥ 38.0ºC; or history of fever during the previous 24 hours.
5. 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.

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.
