Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

\- Healthy male subjects,aged 18 to 40 years of age included and in good health as determined by past medical history, physical examination, vital signs, ECG, and laboratory tests

Exclusion Criteria

* History of hypersensitivity to any of the study drugs or to drugs of similar chemical classes.
* Known history or current clinically significant ECG abnormalities or arrhythmias.
* Symptoms, physical signs and laboratory values suggestive of systemic disorders including renal, hepatic, cardiovascular, pulmonary, skin, immunodeficiency, psychiatric, or other conditions which could interfere with the interpretation of the study results or compromise the health of the subjects.
* Sexually active males must use a condom during intercourse while taking drug and for al least 4 weeks after stopping study medication and should not father a child during this period.
* History of malaria or residence in a malaria-endemic area over a period of 6 months before study entry. - Any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk or render the subject unable to meet requirements of the protocol.
