Clinical Trial Summary

This is a Phase 1a, randomized, double-blind, single ascending dose study, designed to assess the safety, tolerability, and PK of a single CSX-1004 injection, administered by IV infusion across a range of doses in healthy adult subjects. The study will have 3 phases: Screening, Inpatient Treatment, and Outpatient Follow-up.

The primary objective of the study is to determine the safety and tolerability of CSX-1004 Injection administered by intravenous (IV) infusion across a range of doses in healthy adult subjects.

The secondary objective of the study is to determine the pharmacokinetics (PK) of CSX-1004 Injection administered by IV infusion across a range of doses in healthy adult subjects.
