Management for PAF
      
                        Treatment of perianal Crohn's disease has been a major problem till now. There are number of treatment modalities available including medical and surgical procedures such as:

              Antibiotics: Provide transient relioefe with 90% recurrence

              Immunosuppresents: Lack of robust clinical data and high side-effects
      
                                    
                                Image
              Anti-TNF: Strong evidence, early and sustained remission but multiple injections required with higher cost
      
                                    
                                Image
              Surgical drainage is the last resort with temporary improvement and high relapse rate
      
                                    
                                Success rates with any modality reach approximately 50% and 70% relapse on discontinuation of treatment. Surgical therapies associated with high recurrence rate and side effects like sphincter dysfunction.
      
                                
            Mechanism of action of Stempeucel
      
             Immunoregulatory activity reduces inflammation, which allows the tissues around the fistula tract to heal.

              Clinical Trial Design - Perianal fistulizing Crohn's disease
      
                An open label, single arm, investigator initiated Phase I/II study to assess the safety and efficacy of local administration of Stempeucel® in Patients with perianal fistulizing Crohn's disease.
Total Patients: 10 in single site (AIIMS, New Delhi) Investigator : Dr Vineet Ahuja, AIIMS
To evaluate the safety of perianal administration of Stempeucel®
- The type of adverse events AE(s), number of AE(s) and proportion of patients with AE(s)
 - Assessment of clinical laboratory parameters
 - Physical examination findings and assessment of vital signs
 - Assessment of electrocardiogram (ECG) parameters
 
To assess the efficacy of perianal administration of Stempeucel®
- Remission of draining fistula at week 24, defined as the clinical closure of all treated external openings that were draining at baseline, and the absence of collections larger than 2 cm in MRI
 - Remission of draining fistula at week 104, defined as the clinical closure of all treated external openings that were draining at baseline, and the absence of collections larger than 2 cm in MRI
 - Changes in the Perianal Disease Activity Index (PDAI).
 - Change in IBD control quality of life questionnaire scores
 - Change in Crohn's Disease Activity Index (CDAI)
 - Change in MRI scores (Van Assche index)
 - Time to remission / Time to response / Time to relapse
