• Consumption of alcohol within 72 hours before administration of the study drug

• Positive test results for drug of abuse during the Screening period or on Day -1

• The participant has a condition or is in a situation which, in the Investigator's opinion, may put the participant at significant risk, may confound the study results, or may interfere significantly with the participant's participation in the study

• Directly or indirectly involved in the conduct and administration of this study as an Investigator, Sub-investigator, study coordinator, or other study staff member; or employee of the Sponsor, or a first-degree family member, significant other, or relative residing with one of the above persons involved directly or indirectly in the study

• Female participant who is breastfeeding

• Evidence of a recent (within 6 months of Day 1) systemic fungal infection, requiring inpatient hospitalisation, and/or antifungal treatment

• Any infection requiring hospitalisation or treatment with IV anti-infectives (including anti-viral treatment) within 4 weeks prior to Screening

• Participant received a Bacille Calmette-Guérin vaccination within 12 months of Day 1 or any other live vaccine less than 4 weeks prior to Day 1 or is planning to receive any such vaccine over the course of the study

• Judgement by the Investigator that the participant should not participate in the study if they have any ongoing or recent (ie, during the Screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions, and requirements

• Vulnerable participants, eg, kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order

• Participants who cannot communicate reliably with the Investigator
