First-In-Human Study of Apramycin

Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: Apramycin injection; Drug: Placebo injection

• Registration Number: NCT04105205
• Lead Sponsor: Juvabis AG

Brief Summary

This is a first-in-human study to assess the safety, tolerability and pharmacokinetics of escalating single doses of apramycin. This trial will be conducted as a single ascending dose trial in up to 5 sequential dose cohorts (group-comparison). Each cohort will consist of 8 healthy subjects, 6 will receive apramycin and 2 placebo.
