Limited use of other non-prescription medications or dietary supplements not believed to affect subject safety or the overall results of the study, may be permitted on a case-by-case basis following approval by the Sponsor in consultation with the Investigator.) (Note: diazepam interferes with the analysis of blood levels of SJ733 and thus should not have been used for at least 8 weeks prior to administration of the study drug).~* Known severe reaction to mosquito bites other than local itching and redness. Participants are requested to refrain from taking non-approved concomitant medication from recruitment until the conclusion of the study.~Participants who are excluded from participation on study days for any of the above reasons may be eligible to participate on a postponed schedule if the Investigator considers this appropriate.

Study Arms:
- first dose (Type: EXPERIMENTAL): The dose used in the first cohort was determined on the basis of the safety and PK data generated in the FIM study (NCT02661373) currently ongoing in United States (US) and will be 150 mg.
- second dose (Type: EXPERIMENTAL): Depending on the pharmacodynamics data (effect of SJ733 on parasitaemia) obtained from this first cohort, the dose in Cohort 2 may be adjusted but will not exceed 600 mg.

Based on this trial design, predict the completion outcome and termination type (if applicable).
