A Phase 1 interventional study of CSX-1004 and Placebo in Opioid Overdose and Opioid Use Disorder, sponsored by Cessation Therapeutics, Inc.. Completed at 1 site in United States. Open to participants aged 18 Years to 50 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-08-21.
Sponsored by Cessation Therapeutics, Inc. · Phase 1, Interventional, and Treatment
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.
