Randomized, Double-blind, Placebo-controlled Study in Patients With Fistulizing Crohn's Disease
A Randomized, Double-blind, Placebo-controlled Phase I/IIa Study in Patients With Abdominal or Perianal Fistulizing Crohn's Disease to Explore the Safety, Tolerability and Preliminary Efficacy of Locally Administered DLX105.
The primary objective of this study is to investigate the safety and tolerability of locally administered DLX105 in treating enterocutaneous fistulas in Crohn's Disease patients.
The study will consist of a screening period of approx. 2 weeks, a 4-week treatment period and a 2-week follow-up period. An end-of study visit is scheduled on Day 43, 2 weeks after the last study visit.

|
Local Tolerability
Time Frame: each study visit after randomization over a period of 4 weeks
|
Investigator and Patient will assess the local tolerability of DLX105 for each treated fistula using a 10-cm visual analogue scale (VAS) at each study visit.
Changes from Baseline will be reported descriptively.

Reduction of Number of draining fistulas
Time Frame: Day 29 and Day 43 after randomization
|
Reduction of number of draining fistulas of 50% from baseline observed at Visit 10 and confirmed at End of Study Visit.
|
Day 29 and Day 43 after randomization
