Overview

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.

Interventions

  • Drug Regular Insulin
    Administered Intranasally at 76 IU
  • Other 0.9 % Normal Saline
    Placebo Control

Primary outcome measures

  • Safety measured by number of serious adverse events (SAE) and adverse events (AE) [Time frame: 3 weeks]
Secondary outcome measures (5)
  • Treatment adherence as assessed by participant Daily Drug Diaries [Time frame: 3 weeks]
  • Feasibility of virtual training as assessed by the Virtual Training Compliance Checklist [Time frame: Baseline Visit]
  • Acceptability of virtual training as assessed by the Virtual Training and Feasibility and Acceptability Survey [Time frame: Baseline]
  • Feasibility of blood spot collection procedure as measured by a Blood Spot Procedure Compliance Checklist [Time frame: Screening Visit]
  • Acceptability of Blood Spot Procedure, as measured by a Blood Spot Procedure Post-Training Acceptability Survey [Time frame: Screening Visit]

Eligibility criteria

Inclusion criteria

  • Subject is ≥18 and <85 years of age
  • Subject has sustained a traumatic or non-traumatic spinal cord injury with American Spinal Injury Association (ASIA) rating A, B, C or D, complete or incomplete
  • Subject sustained spinal cord injury at least 4 months before baseline visit
  • Female subjects must have either: (1) a negative pregnancy test at the screening and treatment visits OR (2) be at least 2 years post-menopausal / surgically sterile
  • The subject must be proficient in English in order to comply with instructions and measures for the study
  • Subject is able to prepare and administer the study drug as outlined in the protocol or has a carer who is available to do so for the duration of the study

Exclusion criteria

  • Subject is dependent on a ventilator or has a patent tracheostomy site
  • Subject has recent history (within past 6 months) of recurrent autonomic dysreflexia, defined as a sudden rise in systolic BP greater than 20 mmHg or diastolic BP greater than 10 mmHg without rise in heart rate and accompanied by symptoms such as headache, facial flushing, sweating, nasal congestion, or blurry vision
  • Subject has medical history and/or clinically determined disorders: chronic sinusitis, previous nasal and/or oto-pharyngeal surgery and severe deviated septum and/or other anomalies
  • Subject has history of any of the following: active and significant central nervous system, psychiatric illness, pulmonary, or cardiovascular disorders or any other clinically relevant abnormality that inclusion would pose a safety risk to the subject as determined by investigator
  • Subject has participated in a clinical trial investigation within 3 months of this study
  • Subject has a history of allergy, hypersensitivity, or other significant adverse reaction to insulin
  • Subject is taking insulin for Type I or Type II diabetes
  • Subject is pregnant or breast feeding
  • Any other clinically relevant finding that would pose a safety risk to the subject as determined by the investigator
