Evaluation of CN-105 in Subject With Acute Supratentorial Intracerebral Hemorrhage

Summary

Phase 2, randomized, double-blind, placebo controlled study to evaluate the administration of CN-105 in patients with supratentorial intracerebral hemorrhage (ICH). Patients will be evaluated for eligibility within 12 hours of symptom onset. Eligible participants (30 active participants and 30 control participants) will receive CN-105 or placebo administered intravenously (IV) for a 30-minute infusion every 6 hours for up to a maximum of 3 days (13 doses) or until discharge (if earlier than 3 days). Participants will be monitored daily throughout the Treatment phase of the study (up to a maximum of 5 days) and will receive standard-of-care treatment for the duration of the study. Additional protocol assessments will be required during the Treatment phase as outlined in Section 7.5. After discharge from the hospital, participants will enter a 3-month Follow-up phase, with a clinic visit at 30 days and a follow-up telephone interview with telephone-validated mRS at 90 days after first dose of study agent.
