Brief Summary
OSSM-001 will be evaluated in a double blind, randomized phase I safety study of a single injection of 100 and 300 million bone marrow derived MSCs in 16 patients with refractory perianal fistulas in ...
Eligibility Criteria
Inclusion
- Men and Women 18-75 years of age with a diagnosis of unhealing perianal fistulas in the setting of Crohn's disease and must be on maximal standard of care therapy (e.g., antibiotics, 5-ASA, and immunomodulator, anti-TNF, anti-integrin, and anti-interleukin therapies) for at least six months duration.
- Presence of perianal fistula with maximum of two internal fistula tracts and a maximum of three external openings based on clinical assessment and MRI. Fistula must have been draining for at least 6 weeks prior to the screening visit.
- Medically refractory perianal fistulizing Crohn's disease (i.e., standard of care such as antibiotics, immunosuppressives)
- Have no contraindications to MR evaluations: e.g., pacemaker or magnetically active metal fragments, claustrophobia
- Ability to comply with protocol
- Competent and able to provide written informed consent
- Concurrent Crohn's-related therapies with stable doses corticosteroids, 5- ASA drugs, immunomodulators, anti-TNF therapy, anti-integrin and anti-interleukin therapies are permitted.
- A female participant and of childbearing potential must have a negative serum or urine pregnancy test at time of screening, and must not plan to become pregnant during the study.
Exclusion
- Inability to give informed consent.
- Clinically significant medical conditions within the six months before administration of MSCs: e.g. myocardial infarction, active angina, congestive heart failure or other conditions that would, in the opinion of the investigators, compromise the safety of the patient.
- Specific exclusions: Hepatitis B or C, HIV, Abnormal AST or ALT at screening
- History of cancer including melanoma (with the exception of localized skin cancers) in the past five years
- Received treatment with an investigational drug or device within 60 days of randomization or have not completed 5 half-life washout (whichever is later) for drugs or biologics. If the half-life of the product is not known, then subjects cannot be randomized within 6 months of investigation drug treatment.
- Participated in a cell therapy-based trial within 6 months before randomization
- Participated in Crohn's/ulcerative colitis or any fistulizing Crohn's study within 6 months before randomization
- Pregnant or breast feeding or trying to become pregnant.
- Presence of a rectovaginal or perineal body fistula
- Change in Crohn's immunosuppressive regimen prior to enrollment. Subjects should be on stable, maximal medical therapy for 4 months prior to enrollment.
- Uncontrolled intestinal Crohn's disease which will require escalation for medical therapy or surgery within 3 months of enrollment
- Severe anal canal disease that is stenotic and requires dilation or severe proctitis making difficult to the surgery
- A female or male participant unwilling to agree to use acceptable contraception methods during participation in study. Acceptable contraception methods include: Implants, injectables, combined oral contraceptives, an intrauterine device, a bilateral tubal ligation, a vasectomy, a vasectomized partner for female participant, double-barrier methods, and physical barrier if male participant is not vasectomized
- Associated perianal abscess(es).
- Laboratory exclusions: Serum creatinine levels \>1.5 times the upper limit of normal (ULN). Total bilirubin \>1.5 × ULN. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \>5.0 × ULN. Hemoglobin \<10.0 g/dL for females or \<11.0 g/dL for males. Platelets \<75.0 × 109/L.
- Any contraindications to MRI or surgical or anesthetic procedure(s)
- Any major GI surgery or major perianal local surgery within 6 months of randomization
