Study on the Treatment of Anal Fistulas Using Alofisel Versus Fat Autologous Stem Cells (CHAZAM)
Pilot Study on the Treatment of Anal Fistulas in Crohn's Disease Patients Using Alofisel Versus Fat Autologous Stem Cells
One of the newest and most innovative medicinal approaches is cell therapy. Several clinical trials and experimental investigations have looked into the feasibility of treating CD-related fistulas with stem cells.
The current indication for ALOFISEL® (active ingredient: Darvadstrocel) is the treatment of difficult perianal Crohn's fistulas that have not responded well to at least one conventional therapy or biotherapy.
This brand-new cell therapy medication is created using amplified allogeneic human adult mesenchymal stem cells from adipose tissue (ADSC). The supplier mandates that two patients be booked for a single dose of ALOFISEL® due to the medication's expensive price-roughly €54,000 for a single dose of 120 million-which cannot be stored once thawed.
Only one of the two patients receives therapy; the other serves as the backup patient. By doing this, another "back-up" patient who might receive no care at all is avoided.
An developing alternate approach to allogeneic ADSC injection for the treatment of complicated anal fistulas in CD is autologous fat injection. In recent years, autologous fat grafts have been the subject of in-depth research. They are popular because it is simple to get clinical samples (lipoaspirate, adipose tissue), and because there are a lot of ADSCs in adipose tissue. Additionally, ADSCs show strong immunomodulatory and regenerative capacities.
We would wish to compare the effectiveness of these two injection kinds on perianal fistulas as part of our care of CD.

Conditions
Intervention / Treatment
Detailed Description
The trial will be made available to patients who are scheduled for perianal surgery with ALOFISEL® or backup (fat injection). The history and signs of perianal fistula will be noted if the patient doesn't object.
Two visits that correspond to typical follow-up visits for patients will be noted:
Visit following surgery: fistula clinical evaluation, analgesic use, etc. and six months after : clinical assessment, MRI

Comparing the efficacy of Alofisel treatment versus fat grafting in Crohn's disease complex perianal fistulae
Time Frame: 1 month after the surgery

At 1 month, the percentage of healing is defined as the clinical closure of the orifice and the lack of pus draining by pressure on the borders of the fistula scar.
