Brief Summary
Primary objective

Detailed Description
Screening: up to 56 days (Day -56 to Day -2). Treatment: 1 day (treatment on Day 1, study observation period from Day -1 to Day 3). Follow-up and end of study: 105 days after IMP administration (follow up visits from Day 5 to Day 78; End of study visit on Day 106). Total study duration for each participant: approximately 23 weeks.
