Study Description

Brief Summary:

The purpose of this study is to test the safety and tolerability of HFB30132A when it is given by intravenously to healthy participants. Blood tests will be done to check how much HFB30132A is in the bloodstream and how long the body takes to eliminate it. Participation may include up to ten visits to the study center.

Condition or disease	Intervention/treatment	Phase
Healthy	Drug: HFB30132A; Other: Placebo	Phase 1

Detailed Description:

This is a Phase I, first time in human, randomized, double-blind, placebo-controlled, and dose escalation study in healthy volunteers.

The study will comprise of:

1. A Screening Period of up to 30 days (Day -30 through Day -1);
2. A Treatment Period during which participants will be resident at the Observation Unit from Day -1, 1 day before Investigational Medicinal Product (IMP) administration (on Day 1) until at least 24 hours after IMP administration, will be discharged on Day 2 after all safety and/or pharmacokinetic (PK) evaluations have been completed, and
3. A Follow up Period lasting 180 days after the IMP dose. The study will be conducted at a single study center in Cincinnati.
