Study of Allogenic Adipose-derived Stem Cells in Crohn's Fistula (ALLO-ASC)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

Adipose-derived stem cells have properties of differentiation to various types of cells, immunomodulatory effects. adipose-derived stem cells (ASCs) show also low immunogenicity.

Anterogen has developed ANTG-ASC(Autologous ASC) which has shown good efficacy and safety in Phase I and II study on the patients with Crohn's fistula.

However, Crohn's patients are sometimes not fat enough to extract fat tissue for culturing ASCs. Therefore the investigators have planned to study allogenic ASCs for safety and efficacy in patients with Crohn's fistula.

Condition Intervention Phase
Crohn Biological: Allogenic human adipose-derived stem cells Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase I Study of Dose Escalation of Human Allogenic Adipose-derived Stem Cells (ALLO-ASC) to Evaluate Safety and Efficacy in Patients With Crohn's Fistula

Primary Outcome Measures:
  • General safety (Laboratory screening, adverse effects, immunological response, local tolerance) [ Time Frame: Week8 ]

Secondary Outcome Measures:
  • Proportion of patients with sustained efficacy [ Time Frame: Month 8 ]
    Proportion of patients with more than 50% healed fistula at Month 8 Following up whether there is a recurrence at Month 8

  • Proportion of patients with adverse effects [ Time Frame: at month 8 ]
    Evaluate the safety at 8 months whether any kind of AE occurs.

Estimated Enrollment: 6
Study Start Date: September 2011
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment
For ALLO-ASC 1xE7 cells/ml,3 patients are to be enrolled. If there is no safety issue, 3 more patients will be enrolled to be treated with ALLO-ASC 3xE7 cells/ml.
Biological: Allogenic human adipose-derived stem cells
ALLO-ASC 1xE7 cells/mL is injected once along the fistula. If there is no safety issue for 4 weeks, 3 more people could be enrolled who are subject to ALLO-ASC 3xE7 cells/mL.
Other Name: ALLO-ASC
