RECRUITING

NCT07384052

PHASE1

Safety and Feasibility of Intranasal Insulin in Patients With Spinal Cord Injury

Sponsor: HealthPartners Institute

View on ClinicalTrials.gov

Summary

The purpose of this study is to find out whether insulin, a drug approved by the FDA for the treatment of diabetes mellitus, is safe when administered as a nasal spray (intranasally) to people who have experienced a spinal cord injury. While insulin nasal spray has been shown to be safe in many patient populations, it has not yet been studied in people with spinal cord injury. This study would be the first step to developing insulin nasal spray as a treatment for spinal cord injury in the future. This study is recruiting up to 12 individuals who have experienced a spinal cord injury at least 4 months ago to administer either 76 IU insulin nasal spray or a placebo (inactive nasal spray) at home every day for up to 24 days. Participants will be asked questions about their health and symptoms related their spinal cord injury, and will have their blood collected throughout the study. Participants who are unable to administer the medication independently must have a study partner in order to participate.
