A Dose Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of VEL-101

Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: VEL-101; Drug: Placebo

• Registration Number: NCT05238493
• Lead Sponsor: Veloxis Pharmaceuticals

Brief Summary

This study is primarily designed to assess the safety and tolerability of single doses of VEL-101 when administered subcutaneously (via injection into an area under the skin) or intravenously (via infusion into a vein). As each new group of participants is enrolled into the study, the dose administered to that group may be higher than a previous dose shown to be safe in other participants. The study is also designed to determine blood levels of VEL-101 and some substances produced by the immune system following VEL-101 administration. This information can provide insight into how quickly VEL-101 is eliminated from the body and some if its effects on the body.
