Phase 1 Study of HBN-1

Phase 1 First-in Human randomized, open-label, active control standard of care study of the safety of HBN-1 administered as pharmacologically induced hypothermia as an adjunct to standard of care targeted temperature management in adult patients who have experienced out-of-hospital-cardiac arrest. HBN-1 will be administered as an IV solution according to a weight-based escalating loading dose infusion rate scheme involving three sequential cohorts with a loading dose of HBN 1 administered over 60 minutes (Cohort A), 45 minutes (Cohort B), or 30 minutes (Cohort C). For all cohorts, the loading dose will be followed by a 12-hour maintenance infusion of HBN-1. Dosing cohorts will include a minimum of 6 subjects randomized in a 2:1 ratio of HBN-1 plus standard of care versus standard of care alone. Individual cohorts may be expanded to up to a maximum of 12 subjects . If the cohort is expanded, the additional subjects will receive HBN-1 + SOC. During the loading dose and maintenance infusion, physical exam, temperature, assessment of shivering, ECG, vital signs, clinical laboratory, blood alcohol level, and neurologic status will be monitored.
