Eligibility criteria:
Inclusion Criteria:

Body weight between 40 kg and 90 kg inclusive
Presence of P. vivax or P. falciparum monoinfection confirmed by:
Fever, as defined by axillary temperature ≥37.5°C or oral/rectal/tympanic temperature ≥38°C, or history of fever in the previous 48 hours for P. vivax and 24 hours for P. falciparum and,
Microscopically confirmed parasite infection: 1,000 to 40,000 asexual parasite count/µL blood
Written informed consent provided by the patient in accordance with local practice. If the patient is unable to write, witnessed consent is permitted according to local ethical considerations.
Ability to swallow oral medication
The patient is able to understand and comply with protocol requirements, instructions and protocol-stated restrictions and is likely to complete the study as planned
Willing to be hospitalized for at least 72 hours or until malarial parasites are not detected by microscopy on 2 consecutive occasions whichever comes later and return to clinic for all follow-up visits
Women must be of non-childbearing potential (WNCBP) as per one of the following definitions:
postmenopausal defined as having age-appropriate, natural (spontaneous) amenorrhea for at least 12 months prior to screening in the absence of an alternative medical cause for the amenorrhea, or
premenopausal with irreversible surgical sterilization by hysterectomy and/or bilateral oophorectomy or salpingectomy at least 6 months prior to screening (as determined by subject medical history)
Sexually active men must agree to comply with strict appropriate contraception rules (barrier contraception, e.g. condom) or complete abstinence when this is in line with the preferred and usual lifestyle of the patient. The contraception coverage in this situation should ensure full elimination of MMV390048, i.e. until 120 days after MMV390048 administration to the enrolled male patient (covering a full sperm cycle of 90 days starting after 5 x t½ of the drug). Abstinent patients must agree to use the above-mentioned contraceptive methods if they start sexual relationships during the study, and to continue these methods until 120 days after study medication.

Exclusion Criteria:

any other disorder or condition that in the opinion of the investigator may render the patient unfit for participation in the trial, may limit his/her ability to provide informed consent, may interfere with protocol adherence or place the patient at increased risk through participation in the study
