Study Type: Interventional

Official Title: A Multi-Center, Randomized, Controlled, Trial of Cerebrospinal Fluid Drainage (CSFD) in Acute Spinal Cord Injury

Brief Summary: The purpose of this Phase IIB randomized controlled trial is to evaluate the safety and efficacy of CSFD and to provide a preliminary clinical efficacy evaluation of the combination of CSFD and elevation of mean arterial pressure (MAP) in patients with acute spinal cord injury (SCI). The objectives of the trial are to evaluate (i) efficacy of reducing intrathecal pressure (ITP) by CSFD in patients with acute SCI; (ii) preliminary efficacy of combination of CSFD and elevation of MAP compared to elevation of MAP alone in improving neurologic motor outcomes in patients with acute SCI; and, (iii) safety of intensive CSFD in acute SCI patients.

Detailed Summary: Acute spinal cord injury (SCI) affects 10,000-14,000 persons per year in the United States (Burke, Linden et al. 2001). There are 150,000-300,000 persons living with significant disabilities from SCI at any given time (Bernhard, Gries et al. 2005). The average age of incident cases of SCI is 47 years and about 78% of the cases are males (DeVivo and Chen 2011). Estimates of the lifetime costs to care for someone with a SCI range from $325,000 to $1.35 million and the yearly cost to society reaches $8 billion (Sekhon and Fehlings 2001). With better long term care technologies, these costs are expected to continue to rise. Although there have been significant advances in accessibility for people with disabilities, the goal of medical science is to overcome the physiological barriers imposed by the injury itself and allow these individuals to regain their pre-injury level of neurological function (Rowland, Hawryluk et al. 2008). The injury to the spinal cord occurs in two phases. The first phase is the primary physical damage due to the impact energy of the compressive nature of the injury. The damage can be very complex with shearing of the axons, destruction of the cell bodies and disruption of the microvasculature at the site of injury. The secondary phase of the injury begins soon after the primary injury has occurred and can be influenced by many factors such as hypoxia, hypotension, and the extent of the primary injury. Spinal cord ischemia post-injury causes a significant increase in cell death and more significant neurological disability. Limiting tissue hypoperfusion post-injury can decrease the amount of cell death and axonal damage. Lumbar cerebrospinal fluid drainage (CSFD) together with increased mean arterial blood pressure (MAP) in the immediate post-injury period can reduce spinal cord tissue hypoperfusion. By reducing spinal cord hypoperfusion through elevation of MAP, less cell death and axonal damage will occur, leading to an improvement in neurologic

Current Primary Outcome:

  • Change in ITP [ Time Frame: 120 hours ]
    ITP will be measured in both groups every hour for the duration of study treatment for a total of 121 measurements consisting of one pre-treatment measurement (time 0 hours) and 120 measurements during the treatment (time 1—120 hours).
  • Change in International Standards for Classification of Spinal Cord Injury Motor Score (ISNCSCI, formerly ASIA) [ Time Frame: 180 days ]
    ISNCSCI Motor Score will be obtained at hospital arrival (baseline), 72 hours post-injury, 84 days and 180 days post-treatment. The primary endpoint is difference between the Motor Score at 180 days and baseline.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • ISNCSCI Grade [ Time Frame: Change in ISNCSCI grade between 180 days and baseline ]
  • ISNCSCI Sensory Scores [ Time Frame: Change in ISNCSCI Sensory Scores (Light Touch and Pin Prick) between 180 days and baseline ]
  • ISNCSCI Upper Extremity Motor Score [ Time Frame: Change in ISNCSCI Upper Extremity Motor Score between 180 days and baseline ]
  • ISNCSCI Lower Extremity Motor Score [ Time Frame: Change in ISNCSCI Lower Extremity Motor Score between 180 days and baseline ]
  • Spinal Cord Independence Measure (SCIM) [ Time Frame: Spinal Cord Independence Measure (SCIM) at 180 days ]
  • Pain [ Time Frame: Pain Numeric Rating Scale (NRS) at 180 days ]


Original Secondary Outcome: Same as current
