ADAPT Adacolumn Pediatric Trial in Ulcerative Colitis

Study Overview
=================
Brief Summary
-----------------
Children aged up to 18 years with moderately active Ulcerative Colitis (PUCAI:35-64) will receive one weekly Adacolumn® apheresis treatment over 5 consecutive weeks, followed by up to 3 optional Adacolumn® apheresis treatments over 3 consecutive weeks. Primary end point is PUCAI at Week 12. The main part of the clinical investigation will be continued by a one year follow up for responders.

Detailed Description
-----------------
The individual clinical investigation period will be 12 weeks per patient. If the patient will take part in the follow up, the individual clinical investigation period will be 64 weeks. Patients receive one weekly Adacolumn® apheresis over 5 consecutive weeks. The treating investigator may decide to add up to 3 treatments based on his judgment. Treatment details Day -07: Screening; Day 00 Baseline: 1st Adacolumn® apheresis; Day 07: 2nd Adacolumn® apheresis; Day 14: 3rd Adacolumn® apheresis; Day 21: 4th Adacolumn® apheresis; Day 28: 5th Adacolumn® apheresis; Week 12:Final evaluation

Arms and Interventions

| Intervention/Treatment |
| --- |
|Device: Adacolumn®|The medical device Adacolumn® (CE-Mark Certificate G1 07 01 366 76013) is an adsorptive type extracorporeal apheresis column. It has been shown to effectively improve clinical and endoscopic signs and symptoms in UC in adults by removing granulocytes and monocytes and by changing the Cytokine production.|
