      <intervention_model_description>MMV367 will be administered as a single oral dose, with different doses to be tested across and within cohorts. The highest dose of MMV367 administered in this study will be no more than 1500 mg, to determine the maximum parasite killing rate of MMV367. Doses to be tested in Cohort 1 will be 20mg, 90mg and 1500mg. Parasite regrowth following initial parasite clearance is required to effectively characterise PK/PD parameters such as the half maximum effective concentration of MMV367.The Safety Data Review Team will review all safety, PK, and PD data. Doses to be tested in Cohort 2 will be informed by the results obtained in Cohort 1, and will be selected to refine the PK/PD parameter estimates. The SDRT will meet following the completion of Cohort 2 to review all safety, PK, and PD data. If the SDRT deems sufficient data has been obtained to achieve the primary endpoint, a third cohort of participants will not be enrolled.</intervention_model_description>

            -  Normal ECG tracing unless the Principal Investigator or delegate considers an ECG&#xD;
               tracing abnormality to be not clinically relevant.&#xD;
  &#xD;
          Contraception 9. Women of childbearing potential (WOCBP) who anticipate being sexually&#xD;
          active with a male during the trial must agree to use a highly effective method of birth&#xD;
          control (see below) combined with a barrier contraceptive from the screening visit until 34&#xD;
          days after the last dose of MMV367 (covering a full menstrual cycle of 30 days starting&#xD;
          after 5 half-lives of last dose of MMV367) and have a negative urine pregnancy test result&#xD;
          prior to inoculation with the malaria challenge agent on Day 0.&#xD;
  &#xD;
            -  Highly effective birth control methods include: combined (oestrogen and progestogen&#xD;
               containing) oral/intravaginal/transdermal/implantable hormonal contraception&#xD;
               associated with inhibition of ovulation, progestogen-only oral/injectable/implantable&#xD;
               hormonal contraception associated with inhibition of ovulation, intrauterine device,&#xD;
               intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomised&#xD;
               partner, or sexual abstinence or same sex relationship.&#xD;
  &#xD;
            -  Female participants who are abstinent (from penile-vaginal intercourse) must agree to&#xD;
               start a double method if they start a sexual relationship with a male during the&#xD;
               study. Female participants must not be planning in vitro fertilisation within the&#xD;
               required contraception period.&#xD;
  &#xD;
          Women of non-childbearing potential (WONCBP) are defined as:&#xD;
  &#xD;
            -  Natural (spontaneous) post-menopausal defined as being amenorrhoeic for at least 12&#xD;
               months without an alternative medical cause with a screening follicle stimulating&#xD;
               hormone level (FSH) &gt;25 IU/L (or at the local laboratory levels for post-menopause).&#xD;
  &#xD;
            -  Premenopausal with irreversible surgical sterilization by hysterectomy and/or&#xD;
               bilateral oophorectomy or salpingectomy at least 6 months before screening (as&#xD;
               determined by participant medical history).&#xD;
  &#xD;
               10. Males who have, or may have, female sexual partners of childbearing potential&#xD;
               during the course of the study must agree to use a double method of contraception&#xD;
               including condom plus diaphragm, or intrauterine device, or stable&#xD;
               oral/transdermal/injectable/implantable hormonal contraceptive by the female partner,&#xD;
               from the time of informed consent through to 94 days after MMV367 administration. This&#xD;
               has been calculated based on 90 days (one cycle of spermatogenesis) plus 5 half-lives&#xD;
               of the IMP (4 days). Abstinent males must agree to start a double method if they begin&#xD;
               a sexual relationship with a female during the study and up to 94 days after the last&#xD;
               dose of MMV367. Males that are surgically sterile, or who have undergone sterilisation&#xD;
               and have had testing to confirm the success of the sterilisation, may also be included&#xD;
               and will not be required to use above described methods of contraception.&#xD;
  &#xD;
          Exclusion Criteria:&#xD;
  &#xD;

  &#xD;
            4. Presence of current or suspected uncontrolled chronic diseases that may impact&#xD;
               participant safety or interpretation of clinical trial results, such as (but not&#xD;
               limited to) cardiac or autoimmune disease, diabetes, progressive neurological disease,&#xD;
               severe malnutrition, hepatic or renal disease, epilepsy, or asthma.&#xD;

            8. A score of 20 or more on the Beck Depression Inventory-II (BDI-II) and/or a response&#xD;
               of 1, 2 or 3 for item 9 of this inventory (related to suicidal ideation).&#xD;
  &#xD;
               - The BDI-II will be used as a validated tool for the assessment of depression at&#xD;
               screening. Participants that meet criterion 8 will be referred to a general&#xD;
               practitioner or medical specialist as appropriate. Participants with a BDI-II score of&#xD;
               17 to 19 may be enrolled at the discretion of the Investigator if they do not have a&#xD;
               history of the psychiatric conditions mentioned in criterion 6 and their mental state&#xD;
               is not considered to pose additional risk to the health of the participant during the&#xD;
               trial or to the execution of the trial and interpretation of the data gathered.&#xD;
  &#xD;
            9. History of splenectomy.&#xD;
  &#xD;
           10. Symptomatic postural hypotension at screening (confirmed on two consecutive readings),&#xD;
               irrespective of the decrease in blood pressure, or asymptomatic postural hypotension&#xD;
               defined as a decrease of SBP of ≥20 mmHg after 3 min standing and/or a decrease of DBP&#xD;
               of ≥10 mmHg after 3 min standing. This 3 min standing period will commence after the&#xD;

  This is an open-label, adaptive study using the P. falciparum induced blood stage malaria
        (IBSM) model to characterise the pharmacokinetic/pharmacodynamic (PK/PD) profile and safety
        of MMV367 (the IMP). Up to 18 participants will be enrolled in cohorts of up to 6
        participants each. The study will proceed as follows for all participants:
  
          -  Screening period of up to 28 days to recruit healthy adult participants.
  
          -  Day 0: Intravenous inoculation with approximately 2,800 viable P. falciparum-infected
             red blood cells.
  
          -  Days 1-3: Daily follow up via phone call or text message.
  
          -  Days 4-7: Daily site visits for clinical evaluation and blood sampling to monitor
             malaria parasite numbers via quantitative polymerase chain reaction (qPCR).
  
          -  Day 7 PM: Start of confinement within the clinical trial unit.
  
          -  Day 8: Administration of a single oral dose of the IMP (MMV367). Different doses of
             MMV367 will be administered across and within cohorts in order to effectively
             characterise the PK/PD relationship.
  
          -  Days 8-11: Regular clinical evaluation and blood sampling while confined to monitor
             malaria parasite numbers and measure MMV367 plasma concentration.
  
          -  Day 11 AM: End of confinement within clinical trial unit.
  
          -  Days 12-23: Outpatient follow-up for clinical evaluation and blood sampling.
  
          -  Day 24: Initiation of compulsory definitive antimalarial treatment with Riamet®
             (artemether/lumefantrine) and/or other registered antimalarials if required. Treatment
             will be initiated earlier than Day 24 in the event of:
  
          -  Insufficient parasite clearance following IMP dosing
  
          -  Parasite regrowth following IMP dosing Characterising the
             pharmacokinetic/pharmacodynamic relationship of MMV367
  
          -  Participant discontinuation/withdrawal,
  
          -  Investigator's discretion in the interest of participant safety.
  
          -  Day 27: End of study visit for final clinical evaluation and to ensure complete
             clearance of malaria parasites.

             will be initiated earlier than Day 24 in the event of:
  
          -  Insufficient parasite clearance following IMP dosing (parasitaemia not reduced ≥10-fold
             by Day 10 compared with peak parasitaemia on Day 8).
  
          -  Parasite regrowth following IMP dosing (initial parasite clearance is followed by
             asexual parasite regrowth above 5000 parasites/mL).
  
        Characterising the pharmacokinetic/pharmacodynamic relationship of MMV367
  
          -  Participant discontinuation/withdrawal,
  
          -  Investigator's discretion in the interest of participant safety.
  
          -  Day 27: End of study visit for final clinical evaluation and to ensure complete
             clearance of malaria parasitaemia (at least one negative qPCR result required).
  allocation: N/A
  intervention model: Sequential Assignment
  intervention model description: MMV367 will be administered as a single oral dose, with different doses to be tested across and within cohorts. The highest dose of MMV367 administered in this study will be no more than 1500 mg, to determine the maximum parasite killing rate of MMV367. Doses to be tested in Cohort 1 will be 20mg, 90mg and 1500mg. Parasite regrowth following initial parasite clearance is required to effectively characterise PK/PD parameters such as the half maximum effective concentration of MMV367.The Safety Data Review Team will review all safety, PK, and PD data. Doses to be tested in Cohort 2 will be informed by the results obtained in Cohort 1, and will be selected to refine the PK/PD parameter estimates. The SDRT will meet following the completion of Cohort 2 to review all safety, PK, and PD data. If the SDRT deems sufficient data has been obtained to achieve the primary endpoint, a third cohort of participants will not be enrolled.
