New malaria shots could replace daily pills

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Weight ≥50 kg for males and ≥45 kg for females at screening Exclusion Criteria: 1. Serious adverse reaction or serious hypersensitivity to any drug or formulation excipients (Parts A and B), Wellvone®/Mepron® and/or Malarone® (Part B only) 2. Presence or history of clinically significant allergy requiring treatment, as judged by the investigator. Hay fever is allowed unless it is active 3. History of clinically significant cardiovascular, renal, hepatic, dermatological, chronic respiratory or GI disease, neurological or psychiatric disorder, as judged by the investigator 4. Family history of sudden death, or family history of clinically significant cardiovascular disease, as judged by the investigator 5. Systolic BP \>140 or \<90 mmHg, diastolic BP \>90 or \<50 mmHg, or heart rate (HR) (based on vital signs assessment) \>100 or \<45 bpm, confirmed by repeat assessment at screening 6. Any finding in the medical examination (including BP, HR or ECG) deviating from normal and assessed as clinically relevant by the investigator 7. History or presence of known structural cardiac abnormalities, family history of long QT syndrome, cardiac syncope or recurrent, idiopathic syncope, exercise related clinically significant cardiac events. Any clinically significant abnormalities in rhythm, conduction or morphology of resting ECG or clinically important abnormalities that may interfere with the interpretation of QT changes 8. Presence of sinus node dysfunction, clinically significant PR interval prolongation (\>220 msec), intermittent second- or third-degree atrioventricular block, complete bundle branch block, sustained cardiac arrhythmias including (but not limited to) atrial fibrillation or supraventricular tachycardia; any symptomatic arrhythmia with the exception of isolated extra systoles, abnormal T wave morphology which may impact on the QT/QTc assessment, or QTcF \>450 msec based on the mean of the triplicate values and confirmed by single repeat assessment at screening 9. Participants with a history of cholecystectomy or gall stones 10. Participants who do not have suitable veins for multiple venepunctures/cannulation as assessed by the investigator or delegate at screening 11. Participants with tattoos or scars or other significant dermatological conditions overlying the deltoid or gluteal region which may interfere with injection site assessments, as determined by the investigator or delegate at screening 12. Clinically significant abnormal clinical chemistry, haematology, coagulation or urinalysis as judged by the investigator (laboratory parameters are listed in the study protocol). Participants with Gilbert's Syndrome are not allowed 13. Dyslipidaemia (cholesterol and/or triglycerides) requiring pharmacological intervention or fasting triglycerides \>2.26 mmol/L, fasting cholesterol \>6.20 mmol/L, low density lipoprotein cholesterol \>3.75 mmol/L) 14. Fasting blood glucose ≥6.1 mmol/L 15. Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) 1 and 2 antibody results 16. Transaminases (ALT or AST) \>ULN 17. Females who are pregnant or lactating (all female participants must have a negative highly sensitive serum pregnancy test at screening and a negative urine pregnancy test at admission) 18. Part A only: females of childbearing potential. A woman is considered of childbearing potential unless she is permanently sterile (hysterectomy, bilateral salpingectomy, and bilateral oophorectomy) or is post-menopausal (had no menses for 12 months without an alternative medical cause and a serum follicle stimulating hormone \[FSH\] concentration ≥40 IU/L). 19. Participants who have received any IMP in a clinical research study within the 90 days prior to Day 1, or less than 5 elimination half-lives prior to Day 1, whichever is longer 20. Participants who have previously been administered MMV055 in this study 21. Participants who report to have previously received MMV371 22. Donation of blood or plasma within the previous 3 months or loss of greater than 400 mL of blood 23. Participants who are taking, or have taken, any prescribed or over-the-counter drug or herbal remedies (other than up to 4 g of paracetamol per day, up to 800 mg ibuprofen per day, hormonal contraception or HRT) in the 14 days before IMP administration (see study protocol). Exceptions may apply, as determined by the investigator, if each of the following criteria are met: medication with a short half-life if the washout is such that no pharmacodynamic activity is expected by the time of dosing with IMP; and if the use of medication does not jeopardise the safety of the trial participant; and if the use of medication is not considered to interfere with the objectives of the study. 24. Participants who are taking, or who have taken, rifampin/rifabutin, tetracycline and indinavir in the 30 days before IMP administration (Part B only) 25. Live vaccines within 30 days of IMP administration, or plans to receive such vaccines during the study 26. Participants who have had a COVID 19 vaccine within 14 days before dosing 27. History of any drug or alcohol abuse in the past 2 years 28. Regular alcohol consumption in males \>21 units per week and in females \>14 units per week (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 units = 125 mL glass of wine, depending on type) 29. A confirmed positive alcohol breath test at screening or admission 30. Current smokers and those who have smoked within the last 12 months 31. Current users of e-cigarettes and nicotine replacement products and those who have used these products within the last 12 months 32.
