Further study details as provided by Nordic Drugs AB:

Primary Outcome Measures:
  • Clinical evaluation of fistula healing, change from baseline [ Time Frame: week 8 and 24 ]
    Fistula assessed as healed/not healed

Secondary Outcome Measures:
  • Anal ultrasonography, change from baseline [ Time Frame: week 8 and 24 ]
    Healed/not healed

  • Patient assessment of Symptoms and Impact on Daily Function, change from baseline [ Time Frame: week 8 and 24 ]
    By the use of VAS scales and questionnaires the patients subjective evaluations of symptoms and impact on daily living will be assessed

  • Safety, change from baseline [ Time Frame: week 2, 8, 24 ]
    Standard collection of adverse events and adverse device effects.

Enrollment: 28
Study Start Date: December 2011
Study Completion Date: January 2013
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: KULIST
Medical Device, Activated carbon
Device: KULIST
Twice daily dosing for 8 weeks

Detailed Description:

Patients with chronic uncomplicated perianal fistulas located below levator ani will be treated twice daily with KULIST for 8 weeks. The efficacy will be evaluated by means of an overall clinical evaluation of fistula closure, as well as by anal ultrasonography.

Also changes in Patient Assessment of Symptoms and Impact on Daily Function will be evaluated. Safety will be evaluated by standard adverse event /adverse device effects reporting.
