About

Safety and Efficacy of ECMT-100 for the Treatment of Anorectal Fistulas

Full description

ECMT-100 is a colloidal hydrogel derived from extracellular matrix (ECM), formulated to adhere to sub-epithelial soft tissue and allow for filling of anorectal fistulas to reinforce and promote fistula tract closure. ECMT-100 is a medical device and should be administered via catheter within the fistula tract following curettage of the tract, with draining setons used preoperatively.

ECMT-100 is a mucoadhesive hydrogel composed of ECM formulated to adhere to the gastrointestinal mucosa, fill the transsphincteric fistula tract, and promote tract closure by allowing for timely host tissue integration without fecal incontinence.

• Autoimmune disease that is not stable.
• Subjects who are immunocompromised such as known human immunodeficiency virus (HIV) or currently receiving chemotherapy or radiation therapy.
• Ongoing use of antiplatelet drugs. Subjects may be included in the study if antiplatelet drugs have been stopped for 5 to 7 days prior to surgery.
