Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This intervention requires a single procedure of allogeneic human amnion epithelial cells (hAEC) obtained from the placentas of consenting healthy donors delivering at-term healthy babies at Monash Health, obtained under Good Manufacturing Practice-like conditions for clinical trial use. 20 million to 60 million cells will be administered per patient in 4-12 injections into the rectum (based on the baseline length of disease) during colonoscopy by a specialist gastroenterologist in our endoscopy suite at our quaternary Australian hospital. The overall estimated duration of injection will be approximately 30 minutes. The anaesthesia administered will be deep sedation as per routine general colonoscopy. The entire endoscopic procedure will be recorded and read by the endoscopist and a central reader as well as recorded in a procedural report.

Outcomes
Primary outcome [1] 337991 0
The primary outcome is safety with an adverse event defined as any of the following 1) worsening (change in nature, severity or frequency) of ulcerative proctitis present at the time of the study based on the Modified Mayo Score, 2) intercurrent illness based on patient self-reporting, 3) abnormal laboratory values (FBE, UEC, LFT, CRP) defined as clinically significant shifts from baseline within the range of normal that the investigator considers to be clinically significant or 4) clinically significant abnormalities in physical examination, vital signs, weight and drainage for the perianal fistulas. A causality assessment will be performed regarding adverse events and defined as one of the following: unrelated, unlikely, possible or probable.

The severity of AEs will be graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), v5.0. A serious adverse event (SAE) is any untoward medical occurrence that occurs at any dose. An AE in a clinical trial is designated to be serious if it results in death, is life-threatening, requires inpatient hospitalisation, or prolongs existing hospitalisation, results in persistent or significant disability or incapacity.
Timepoint [1] 337991 0
The primary outcome timepoint is assessed at week 12 after administration of intervention.
Secondary outcome [1] 434038 0
Feasibility of route of stem-like cell administration based on a specifically designed questionnaire for investigator completion.
Timepoint [1] 434038 0
The secondary outcome timepoint is assessed at week 12 after administration of intervention.
Secondary outcome [2] 434039 0
Efficacy of treatment
This will be assessed based on symptoms (stool frequency, rectal bleeding) using the Modified Mayo Score and the baseline and week 12 Mayo endoscopic subscore as a composite outcome.
Timepoint [2] 434039 0
The secondary outcome timepoint is assessed at week 12 after administration of intervention compared with baseline assessment of symptoms and endoscopic subscore.
Secondary outcome [3] 434040 0
Health-related quality of life assessed by the Short Inflammatory Bowel Disease Questionnaire
Timepoint [3] 434040 0
The secondary outcome timepoint is assessed at week 12 after administration of intervention.

Summary
Brief summary
Apart from topical aminosalicylates and steroids, there is limited local treatment available for ulcerative proctitis, a incurable relapsing inflammatory condition of the bowel. This study aims to assess the safety of using locally injected stem cells derived from healthy placentas to treat ulcerative proctitis. Participants will receive a single injection of cells during routine colonoscopy and undergo assessment using routine colonoscopy, blood tests and stool tests. We hypothesise that these placental-derived stem cells will be safe and well-tolerated and that local injection is feasible.
