Unable, as determined by the investigator, or unwilling to discontinue use of potent P-glycoprotein (P-gp) inhibitors for the first 35 days of the study 6. Unable, as determined by the investigator, or unwilling to discontinue use of potent cytochrome P450 (CYP) 3A4/5 inducers for the first 35 days of the study 7. Renal compromise (serum creatinine greater than 1.5 times the age- and sex-appropriate upper limit of normal [ULN]) at screening before the first dose of study drug 8. Severe Hepatic dysfunction (serum alanine transaminase [ALT], aspartate transaminase [AST], and/or gamma-glutamyltransferase [GGT] ALL greater than 2.5 times the age- and sex-appropriate ULN) or hepatic impairment (detectable ascites, serum bilirubin greater than 2 mg/dL, serum albumin less than 3.5 g/dL, and prothrombin time prolonged by more than 6 seconds above the ULN for the local laboratory in the absence of anticoagulant therapy) at screening before the first dose of study drug 9. Concomitant spinal cord injury or abnormality as determined by routine imaging: 1. Conclusive radiological evidence of complete spinal cord transection 2. Multiple injuries to the neurological spinal cord at different levels 10. History of symptomatic cervical spinal stenosis with myelopathy as a factor confounding participant assessment 11. Unlikely to be available for follow-up as specified in the protocol 12. Participated in a previous clinical study and received an investigational product within 30 days of screening 13. Previous exposure to SUN13837 14. Allergy to SUN13837 or any of its excipients 15. Any other issue which, in the opinion of the investigator, made the participant unsuitable for study participation.

Outcome

Type Measure Description Time frame Safety issue
Primary Total Spinal Cord Independence Measure, Version III (SCIM III) Score Following Treatment With SUN13837 Injection or Placebo in Adult With Acute Spinal Cord Injury The SCIM III is a comprehensive rating scale that measures the ability of participants with spinal cord injury to perform everyday tasks. The SCIM III has 19 items that assess 3 domains: Self-Care (6 items, scores range from 0 to 20), Respiration and Sphincter Management (4 items, scores range from 0 to 40), and Mobility (9 items, scores range from 0 to 40). The total SCIM score ranges from 0 to a maximum of 100 points in an individual with a fully functional spinal cord. A score of 0 indicates a worse outcome and a score of 100 indicates a better outcome. An improvement of at least 4 points of the total SCIM showed a small significant improvement, and 10 points showed a substantial improvement. Week 2, week 4, week 8 and week 16 post dose.
Secondary Sensitivity Analyses of Total Spinal Cord Independence Measure, Version III (SCIM III) Score at Week 16 by Treatment Group The SCIM III is a comprehensive rating scale that measures the ability of participants with spinal cord injury to perform everyday tasks. The SCIM III has 19 items that assess 3 domains: Self-Care (6 items, scores range from 0 to 20), Respiration and Sphincter Management (4 items, scores range from 0 to 40), and Mobility (9 items, scores range from 0 to 40). The total SCIM score ranges from 0 to a maximum of 100 points in an individual with a fully functional spinal cord. A score of 0 indicates a worse outcome and a score of 100 indicates a better outcome. An improvement of at least 4 points of the total SCIM showed a small significant improvement, and 10 points showed a substantial improvement. Week 16 post dose
Secondary Change From Baseline of Total Motor Score (TMS) of International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) Following Treatment With SUN13837 Injection or Placebo in Adult With Acute Spinal Cord Injury TMS was the sum of the overall Upper Extremity Motor Score (UEMS) and the overall Lower Extremity Motor Score (LEMS) of ISNCSCI. The score on the scale runs from a minimum value of 0 to a maximum of 100 points in an individual with a fully functional spinal cord. A score of 0 indicates a worse outcome and a score of 100 indicates a better outcome. The UEMS was defined as the sum of the motor function scores in the cervical spinal segments C5, C6, C7, C8, and T1. A separate sum was obtained for the right and left sides (a maximum of 25 points each) and for an overall score (with a maximum score of 50). The LEMS was defined as the sum of the motor function scores in the spinal segments lumbar level 2, lumbar level 3, lumbar level 4, lumbar level 5, and sacral level 1. A separate sum was obtained for the right and left sides (a maximum of 25 points each) and for an overall score (with a maximum score of 50). Baseline to Day 3, Week 2, Week 4, Week 8, and Week 16 post dose.
Secondary Self-Care and Mobility Subscale Scores of Spinal Cord Independence Measure, Version III (SCIM III) Score Following Treatment With SUN13837 Injection or Placebo in Adult With Acute Spinal Cord Injury The SCIM III is a comprehensive rating scale that measures the ability of participants with spinal cord injury to perform everyday tasks. The SCIM III has 19 items that assess 3 domains, two of which are Self-care and Mobility. The self-care domain is a subscale of 6 items and scores range from 0 to 20 (higher scores indicate a better outcome). The mobility domain consists of 9 items with subscale scores range from 0 to 40 (higher scores indicate a better outcome). The score for the combined Self-Care and Mobility subscale ranges from 0 - 60 points; higher scores indicate a better outcome Week 2, Week 4, Week 8, and Week 16 post dose.
Secondary Upper Extremity Motor Scores (UEMS) of International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) Following Treatment With SUN13837 Injection or Placebo in Adult With Acute Spinal Cord The UEMS was defined as the sum of the motor function scores in the cervical spinal segments C5, C6, C7, C8, and T1. A separate sum was obtained for the right and left sides (a maximum of 25 points each) and an overall score of 0-50 with a maximum score of 50. A higher score indicates a better outcome. Baseline to Day 3, Week 2, Week 4, Week 8, and Week 16 post dose.
Secondary Lower Extremity Motor Scores (LEMS) of International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) Following Treatment With SUN13837 Injection or Placebo in Adult With Acute Spinal Cord Injury The LEMS was defined as the sum of the motor function scores in the spinal segments lumbar level 2, lumbar level 3, lumbar level 4, lumbar level 5, and sacral level 1. A separate sum was obtained for the right and left sides (a maximum of 25 points each) and for an overall score with a maximum score of 50. A higher score indicates a better outcome. Baseline to Day 3, Week 2, Week 4, Week 8, and Week 16 post dose.
Secondary Incidence of Adverse Events Reported in = 20% of Participants Following Treatment With SUN13837 Injection or Placebo in Adult With Acute Spinal Cord Injury The protocol defined an adverse event (AE) as any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. Baseline up to approximately Day 182 post dose.
