Safety of Allogeneic Human Umbilical Cord Mesenchymal Stem Cells (UC-MSCs) to Treat Perianal Fistulas w/ Crohn's Disease

Phase 1RecruitingNCT05039411

CryoCord Sdn Bhd5 enrolled

Overview

Objectives: Primary: To demonstrate the safety of allogeneic UC-MSCs administered by injection for complex perianal fistulas in patients with Crohn's disease Secondary: To determine the efficacy of a single/multiple allogeneic UC-MSCs injection in improving complex perianal fistula complications and (re-epithelialization of the external openings).

Design and Investigation: Number of Patients: 5 (including a consideration of 20% \[1 patient\] dropout from the trial) Dosage and mode of administration Dosage: A total of 60 million PF2020-CELL (UC-MSCs) will be injected locally around the fistula tract, with a separation of 1 cm between injections. All patients will receive a total of 60 million cells per visit for 5 visits, with a 6 - 12 weeks interval between the injections. If the patient is completely healed during any course of stem cell injections, subsequent stem cell treatments can be discontinued. However, patients will still be required to undergo regular follow-up examinations, including physical examinations and other medical tests, until the study is completed. Mode of administration: The procedure involves localizing the fistulous tract, performing curettage and closing the internal opening, and the injection of PF2020-CELL (UC-MSCs). The indicated dose of PF2020-CELL (UC-MSCs) will be injected starting from the tissues around the internal orifice or orifices and then progressing towards the external opening.

Outcomes

Primary Outcomes

No incidence of treatment-emergent adverse events (TEAEs)

example of TEAEs are pyrexia (non-persistent fever, \<38.5°C), infection, perianal abscess, enlargement of fistula \& allergic reaction.

Time frame: Throughout study completion, an average of 1.5 year

Secondary Outcomes

Clinical healing

Mainly on re-epithelialization of external opening

Time frame: Visits 5, 9, 13, 17, 21 (approximately 6 to 12 weeks between visits)
