Primary Outcome Measures:
  • Performance of I-020805 in prevention of CSF leakage [ Time Frame: Intraoperative on the day of sugery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Incidence of CSF leakage [ Time Frame: Within 7 days after surgery or prior to discharge ] [ Designated as safety issue: No ]
  • CSF leakage or pseudomeningocele related surgical intervention [ Time Frame: Within 90 days following surgery ] [ Designated as safety issue: No ]
  • CSF leakage confirmed by clinical evaluation or diagnostic testing [ Time Frame: Within 90 days following surgery ] [ Designated as safety issue: No ]
  • Surgical infection and unexpected neurological signs [ Time Frame: Post-operative and within 7 days and 90 following surgery ] [ Designated as safety issue: Yes ]
  • Wound healing impairment [ Time Frame: Throughout study up to 90 days following surgery ] [ Designated as safety issue: Yes ]
  • Incidence of all and treatment emergent adverse events [ Time Frame: Throughout study up to 90 days following surgery ] [ Designated as safety issue: Yes ]

Enrollment: 41
