A Safety Study for Cethrin (BA-210) in the Treatment of Acute Thoracic and Cervical Spinal Cord Injuries

Phase 1

Completed

• Conditions: Spinal Cord Injury
• Interventions: Drug: Cethrin

• Registration Number: NCT00500812
• Lead Sponsor: Vertex Pharmaceuticals Incorporated

Brief Summary

This trial is a multi-center, open-label, dose-escalation study designed to evaluate the safety, tolerability and pharmacokinetics of Cethrin in two types of spinal cord injury patients: those with a complete cervical injury or a complete thoracic injury. Dose levels from 0.3 mg - 9 mg of Cethrin will be administered.

Inclusion Criteria

Patients will be enrolled in this study only if they meet all of the following criteria:

• Informed Consent Form signed by the patient or patient's legal representative.
• Male or female, aged 16-70 years, inclusive.
• For Group 1, patients with acute thoracic (T2-T12) spinal cord injury; for Group 2, patients with acute cervical (C4-T1) spinal cord injury. The site of surgery should be able to accommodate a minimum volume of 2 mL of fibrin sealant.
• Scheduled to undergo spinal decompression surgery or other interventional spinal surgery (e.g., fixation) within 7 days of injury.

Exclusion Criteria

Patients will not be enrolled in this study if they meet one of the following criteria:

• Use of any experimental drug, or participation in any clinical trial, within 30 days prior to surgery.

• History of adverse reaction to fibrin sealant.

• History of hypersensitivity to bovine products.

• Any medical condition that may interfere with the ASIA assessments.

• Clinically significant neurological, cardiac, respiratory, hepatic, or renal disease or malignancy.

• Hemophilia or other bleeding abnormality as defined by:

  • Platelet level lower than 100 X 109/L
  • Activated partial thromboplastin time or international normalized ratio higher than the upper limit of normal
  • Baseline hematocrit lower than 0.25

• Gunshot wound as the presenting injury, or any evidence of transecting injury to the spinal cord (e.g., by stab wound).

• Cognitive impairment which may preclude accurate neurological assessments (e.g. traumatic head injury with GCS of less than or equal to 14).

• Ankylosing Spondylitis.

• Diabetes mellitus requiring insulin therapy.

• Known immunodeficiency, including Acquired Immune Deficiency Syndrome or use of immunosuppressive or cancer chemotherapeutic drugs.

• Pregnancy or breastfeeding during the study. A serum pregnancy test will be performed at Screening for female patients of childbearing potential. In addition, patients who are considered likely to be pregnant may be excluded at th Investigator's discretion.

• Any condition or situation likely to cause the patient to be unable or unwilling to participate in study procedures or participate in all scheduled study assessments, including follow up through Month 6.

• Any condition likely to result in the patient's death within the next 6 Months.

• Any other condition that, in the opinion of the Investigator, would preclude the patient's participation in the study.

• Previous participation in this study.

• Use of intravenous heparin in previous 48 hours, thrombolytics and/or aspirin containing products in the previous 10 days.

• Non-traumatic causes of spinal cord injury (e.g. transverse myelitis, acute disc herniation, etc...).
