Long-term Follow-up with Darvadstrocel for Perianal Fistula
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to assess the long-term effects and symptom improvement of Darvadstrocel, a cell therapy, in people with complex perianal fistulas. Participants will not receive new treatment during this trial; instead, researchers will observe outcomes from previous treatments. The trial seeks individuals who completed the ADMIRE-CD II study within the last three months. As a Phase 3 trial, this study represents the final step before potential FDA approval, offering participants a chance to contribute to the validation of a promising treatment.
Will I have to stop taking my current medications?
The trial does not specify whether you need to stop taking your current medications, but since participants will not receive any drug in this study, it seems unlikely that you would need to stop.
Is there any evidence suggesting that Darvadstrocel is likely to be safe for humans?
Research has shown that darvadstrocel is generally safe for treating complex perianal fistulas. Studies indicate that people tolerate it well. For instance, one study found that symptom relief lasted up to 104 weeks after treatment. Another study reported no major safety issues for up to 156 weeks. Additionally, a long-term follow-up study found no new safety concerns three years after treatment. Overall, these findings suggest that darvadstrocel is a promising and safe treatment option.12345
Why are researchers excited about this trial?
Unlike the standard treatments for perianal fistulas, which often involve antibiotics or surgery, Darvadstrocel offers a novel approach by using stem cells. Researchers are excited about Darvadstrocel because it utilizes expanded adipose-derived stem cells (eASCs) to potentially promote healing from within. This method targets the underlying issue by harnessing the regenerative power of stem cells, which is different from simply addressing symptoms or removing damaged tissue. This innovative approach could lead to more effective and less invasive treatment options for patients.
What evidence suggests that Darvadstrocel is effective for perianal fistula?
Research shows that darvadstrocel may help treat complex perianal fistulas in people with Crohn's disease. In earlier studies, about half of the patients who received darvadstrocel experienced significant symptom improvement or resolution. Predictions based on trial data and real-world evidence suggest these benefits could last up to 104 weeks. This trial will observe participants who previously received darvadstrocel for long-term efficacy and safety. Overall, darvadstrocel appears to be generally well-tolerated and may provide lasting symptom relief.26789

Interventions
- Darvadstrocel
Trial Overview
The trial is not testing a new treatment but is focused on long-term follow-up to monitor side effects and symptom improvement in patients who were treated with Darvadstrocel for complex perianal fistula.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Placebo Group
Participants who received a single dose of darvadstrocel, 120 million cells, intralesionally previously in the ADMIRE-CD II study were observed for efficacy and safety. No drug was administered in this study.
Participants who received darvadstrocel placebo-matching expanded adipose-derived stem cells (eASCs) intralesional injection previously in the ADMIRE-CD II study were observed for efficacy and safety. No drug was administered in this study.
