Clinical Trial: Stem Cell Fistula Plug in Cryptoglandular Perianal Fistulas (MSC-AFP)
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Interventional
Official Title: A Phase I Study of Autologous Mesenchymal Stromal Cell Coated Fistula Plug in Patients With High, Transsphincteric Cryptoglandular Perianal Fistulas
Brief Summary: The investigators propose to study the safety of autologous mesenchymal stromal cell transfer using a biomatrix (the Gore Fistula Plug) in a Phase I study using a single dose of 20 million cells. 15 adult patients, ages 18 years and older with cryptoglandular fistulas will be enrolled. Subjects will undergo standard adjuvant therapy including drainage of infection and placement of a draining seton. Six weeks post placement of the draining seton, the seton will be replaced with the MSC loaded Gore Fistula Plug; fistula plug as per current clinical practice. The subjects will be subsequently followed for fistula response and closure for 24 months. This is an autologous product derived from the patient and used only for the same patient.
Detailed Summary: The investigators propose to study the safety of autologous mesenchymal stromal cell transfer using a biomatrix (the Gore® Bio-A® Fistula Plug) in a Phase I study using a single dose of 20 million cells. 15 adult patients (age > 18 years) with cryptoglandular fistulas will be enrolled. Subjects will undergo standard adjuvant therapy including drainage of infection and placement of a draining seton. Six weeks post placement of the draining seton, the seton will be replaced with the MSC loaded Gore® fistula plug as per current clinical practice. The subjects will be subsequently followed for fistula response and closure for 24 months. Study visits are Day 1, Week 2, Week 4, Week 8, Week 12, Week 24, Week 52, and Week 104. This is an autologous product derived from the patient and used only for the same patient.
