What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to determine if endothelial cells derived from human umbilical vein are safe for use in conjunction with fistulotomy for the treatment of simple anal fistulas. Endothelial cells are a special kind of cell in the body that line the inside surface of blood vessels. The goal of the study is to evaluate the preliminary safety of human umbilical vein cells in anal fistula healing.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are on ongoing steroid treatment or have been treated with steroids in the last 4 weeks.

What data supports the effectiveness of the treatment E-CEL UVEC, AB-207 for anal fistulas?

Research shows that using stem cells from fat tissue has been promising in treating complex perianal fistulas, which are similar to anal fistulas. This suggests that E-CEL UVEC, which may involve similar cell therapy, could be effective for anal fistulas.12345

Are You a Good Fit for This Trial?

Adults with simple anal fistulas, not exceeding 2 tracts or 3 inches in length, without Crohn's disease/Ulcerative Colitis. Participants must be able to consent and agree to a fistulotomy surgery. They should not have certain health conditions like severe renal or hepatic impairment, active infections, or recent major surgeries. Contraception use is required for those who can conceive.

Inclusion Criteria

Maximum tract length of 3 inches
Subject must be willing to use a highly effective method of contraception from the start of the screening period throughout the study period
For female subjects of childbearing potential: A negative serum or urine pregnancy test at screening is required prior to enrollment

Published Research Related to This Trial

Mesenchymal stromal cells (MSCs) from adipose tissue can effectively adhere to suture filaments, promoting better healing of enterocutaneous fistulas (EF) in a rat model, as confirmed by microscopy techniques.
In a study involving 22 Wistar rats, the group treated with suture filaments attached to MSCs showed a significantly greater reduction in fistula size (90.34%) compared to those receiving MSC injections (71.80%) or no treatment (46.54%), suggesting that this method could be a promising new approach for EF treatment.
Mesenchymal stromal cells from adipose tissue attached to suture material enhance the closure of enterocutaneous fistulas in a rat model.Volpe, BB., Santos Duarte, Ada S., Ribeiro, TB., et al.[2018]
In a study of 8 patients with complex fistulas, all 4 enterocutaneous fistulas (ECFs) treated with vacuum-assisted closure (VAC) therapy closed spontaneously, demonstrating its efficacy in managing this challenging condition.
VAC therapy not only promotes skin healing but also aids in the management of enteroatmospheric fistulas (EAFs), with 3 out of 4 EAFs transitioning to ECFs and one closing spontaneously, suggesting its versatility in treating different types of fistulas.

The use of adult stem cells (ASCs) combined with fibrin glue for treating perianal fistulas demonstrated a strong safety profile, with only two unrelated adverse events reported among 34 patients over a follow-up period averaging 38 to 42 months.
However, only 7 out of 12 patients treated with ASCs plus fibrin glue remained free of fistula recurrence after more than 3 years, indicating that while the treatment is safe, its long-term efficacy in preventing recurrences may be limited.
