TASALL - TachoSil® Against Liquor Leak
TachoSil® Versus Current Practice in Dura Sealing Techniques for the Prevention of Post-operative Cerebrospinal Fluid (CSF) Leaks in Patients Undergoing Skull Base Surgery: An Open Label, Randomised, Controlled, Multi-centre, Parallel Group Efficacy and Safety Trial.
The primary objective is to demonstrate superiority of TachoSil® compared to current practice as an adjunct in sealing the dura mater. The efficacy of the dura mater sealing must be evaluated post-operatively. The secondary objective is to evaluate the safety of TachoSil® as an adjunct in sealing the dura mater.
The trial population will consist of 726 randomised (1:1) patients elected for skull base surgery. The trial duration consists of screening, surgery, efficacy follow-up after 7±1 weeks and safety follow-up 28±2 weeks after surgery.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Main Inclusion Criteria (Positive response):
• Is the surgical approach/procedure consistent with skull base surgery? I.e. one of the following:
- Lateral approach to the foramen magnum: Far lateral, extreme lateral, anterolateral, posterolateral
- Approach to the jugular foramen: Infratemporal, juxta condylar, transjugular
- Approach to the cerebello pontine (CP) angle and petrous apex retrosigmoid
- Approach to the middle fossa: Subtemporal (+/- petrous apex drilling), pterional approach (any fronto temporal approach +/- orbitozygomatic deposition)
- Approach to the anterior fossa: Subfrontal (uni or bilateral)
- Approach to the midline posterior fossa
Main Exclusion Criteria (Negative response):
- Has the patient been subject to neurosurgery involving opening of the dura mater within the last 3 months?
- Is the patient anticipated to undergo any additional neurosurgery involving opening of the dura mater which may affect the efficacy evaluation (e.g. re-operation or anticipation to undergo several neurosurgeries) before the Efficacy Follow-up Week 7±1 week?
- Is the patient anticipated to undergo any additional neurosurgery involving opening of the dura mater which may affect the safety evaluation (e.g. re-operation or anticipation to undergo several neurosurgeries) before the Safety Follow-up Week 28±2 weeks?
The surgical approach/procedure is consistent with any transcranial or transfacial or combination of transcranial - transfacial approaches with wide defect in the skull base? I.e. any of the following:
- Trans basal approach
- Total petrosectomy
- Trans facial approach
- Trans sphenoidal approach
- Endoscopic procedures
- Trans oral approach (and any extension: Le Fort, mandibulotomy)
The surgical approach is consistent with one of the following approaches?
- Translabyrinthine approach
- Retrolabyrinthine approach
- Transcochlear (limited transpetrosal) approach
- Did the arachnoid membrane and the CSF containing system remain intact during surgery?
- Does the patient have more than one dura opening (not including dura openings from extraventricular or lumbar drains)?
- Has TachoSil, fibrin or polymer sealants been used during the current surgery prior to randomization?

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Clinically Evident Verified Post-Operative Cerebrospinal Fluid Leak or Clinically Evident Pseudomeningocele or Treatment Failure
Time Frame: Up to 8 Weeks (7 Weeks ± 1 Week)
|
An assessment was performed daily from randomization to Day of Discharge and at the Efficacy Follow-up visit at week 7 ± 1 week.
Clinically evident cerebrospinal fluid leak was confirmed by: 1. Glucose concentration test and/or 2. β-2-transferrin test.
A clinically evident pseudomeningocele was considered to be present post-operatively if the following criteria were fulfilled: 1.
A subcutaneous, visible/palpable fluctuant fluid accumulation was noted at the site of the surgical incision or adjacent to it; 2. It is suspected the fluid accumulation is cerebrospinal fluid.
A treatment failure was defined as application of a new and/or different treatment after application of the study treatment or a third application of (or part of) the selected study treatment on the outside of the dura.

Up to 8 Weeks (7 Weeks ± 1 Week)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Post-Surgical Non-Clinically Evident Post-Operative Pseudomeningocele
Time Frame: Assessment at least once prior to discharge from neurosurgical ward, with the expected discharge from neurosurgical ward after an average of 10 days (Up to 28 Weeks)
|
Non-clinically evident pseudomeningocele was defined as a cerebrospinal fluid accumulation found on a postoperative computerized tomography (CT) or magnetic resonance imaging (MRI) scan which fulfilled the following criteria according to the radiologist assessment before Day of Discharge: CT Scan-Fluid accumulation seen as Hypodense signal, MRI Scan-Fluid accumulation seen as Hypointense signal in T1-weighted image and/ OR Fluid accumulation seen as Hyperintense signal in T2-weighted image.
