About this study
Official title: A Phase IB/IIA Study of Ossium Vertebral Bone Marrow Derived Mesenchymal Stem Cells (vBM-MSC) for the Treatment of Ileal Anal Anastomosis and Ileal Pouch Fistulas in the Setting of Crohn's Disease of the Pouch
The purpose of this study is to determine the safety and feasibility of using Ossium vertebral Bone Marrow Derived Mesenchymal Stem Cells (vBM-MSC) to treat people with an ileal pouch anal anastomosis (IPAA) who develop a fistula in the setting of Crohn's disease of the pouch.
Read the detailed description
Proctocolectomy with ileal pouch anal anastomosis (IPAA) remains the procedure of choice for patients with ulcerative colitis (UC). IPAA allows at risk tissue to be removed with restoration of intestinal continuity while maintaining favorable long-term functional outcomes and quality of life.1 2 While less than 30% of patients experience short-term postoperative morbidity following IPAA,3-5 up to 15% of pouches will ultimately fail due to technical or inflammatory complications, the majority of which manifest as a fistula from the pouch to the perianal or vaginal locations.1,2,6-8 Pouch failure due to a fistula tract is notoriously difficult to treat. Despite immunosuppressive medications and attempts at local repair, most patients will end up with a pouch excision and permanent ostomy. This can be a devastating outcome in some patients as it impacts body image and quality of life.1
Given the high safety profile, and relative success in treating perianal disease, we sought to use a GMP grade allogeneic bone marrow derived MSCs to establish safety and secondarily monitor for healing in patients with ileal anal anastomosis and ileal pouch fistulas. This trial will use allogeneic bone marrow derived mesenchymal stem cells (MSCs) to produce regenerative signals.
This study will enroll adult men and women who have undergone IPAA at least six months prior and now have a peri-pouch fistula related to Crohn's disease of the pouch. Subjects who are refractory to conventional medical therapy will be considered. Subjects enrolled will be those that meet current indications.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Ossium vBM-MSC in people with Pouch, Ileal and Fistula, run by Anthony Lembo at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 16 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: PI left institution). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Treatment related adverse events (time frame: Month 6). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05075811, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2026.
