The goal of this interventional study is to evaluate the pharmacokinetics, safety, and tolerability of 101-PGC-005 in healthy, adult, human subjects. The main question it aims to answer is what are the single and multi-dose PK properties of 101-PGC-005 in the systemic circulation

Participants will receive a bolus injection of 101-PGC-005 administered intravenously once daily for 3 consecutive days. Blood and urine samples will be collected at predetermined timepoints for analysis.
