Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
It is planned to enroll up to 6 sequential cohorts of 8 healthy male participants and healthy female participants of non-childbearing potential in Part A. In Part B, up to 3 sequential cohorts of 8 healthy male participants and healthy non-pregnant, non-lactating female participants will be enrolled. In each cohort, participants will be randomised in a ratio of 6 active investigational medicinal product (IMP) to 2 placebo.
Part A of the study will include two components, Parts A1 and A2. Part A1 includes two initial cohorts, with planned doses of 40 and 100mg, respectively. It is intended to document the human elimination T1/2 of MMV055, which will then be used to shorten the proposed End of Study (EOS) of 48 weeks, if possible.
All cohorts will follow a sentinel dosing design. On Day 1, two sentinel participants (sentinel group) will be randomly assigned to receive a single IM dose of either active IMP or placebo (1 participant each) to assess safety and tolerability (including ISRs).
The sentinel group will be dosed concomitantly at least 7 days prior to the rest of the cohort (main group). The main group will comprise 6 participants randomly assigned to receive a single IM dose of either active IMP or placebo in a 5:1 ratio to assess safety and tolerability (including ISRs).

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

3. Aged 18 to 60 years inclusive at the time of signing informed consent
4. Must agree to adhere to the contraception requirements defined in the study protocol
5. Healthy male or healthy WONCBP (Parts A and B), or healthy non-pregnant, non-lactating female participants (Part B only) according to the assessment of the investigator, as based on a complete medical history including a physical examination, vital signs, 12-lead ECG, and laboratory safety tests without any clinically significant abnormalities. Safety bloods, urinalysis, ECGs and vital signs to be re-checked at admission and/or pre-dose
6. Body mass index (BMI) of 19.0 to 30.0 kg/m2 as measured at screening
7. Weight ≥50 kg for males and ≥45 kg for females at screening
Exclusion Criteria
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
