- Any uncontrolled or unstable disorder (at the Investigator’s discretion, e.g., unstable Primary Sclerosing Cholangitis), including any clinically significant abnormality identified at Screening (e.g., safety lab parameters, physical exam) that may, according to the Investigator, put the subject at risk or interfere with the study procedures or reliability of study assessments to be done
-Prior use (since IPAA) of any biological treatment, including ustekinumab, anti-TNF agents (e.g., infliximab or adalimumab) or anti-integrin antibodies (e.g., vedolizumab), or treatment with small molecules such as ozanimod or any Janus kinase inhibitor (e.g., tofacitinib)

- Concomitant use, during the study, of any prohibited medication: any anti-inflammatory agents (e.g., 5-ASA or systemically available corticosteroids), biologicals, immunosuppressants, DMARDs, Live
Biotherapeutic Products (LBPs, other than MH002), probiotics, prebiotics, antibiotics, Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) (low dose aspirin excepted), investigational medicinal product (other than MH002) or investigational medical device, opioids or any rectally
administered medication
- Conditions linked to severe immunosuppression (e.g., related to human immunodeficiency virus, malignancies, liver cirrhosis, systemic chemotherapy)
- Increased risk of developing infectious endocarditis including:
-Prosthetic cardiac valves including transcatheter-implanted prostheses and homografts,
-Prosthetic material used for cardiac valve repair such as annuloplasty rings and chords,
-Previous infectious endocarditis,
-Unrepaired cyanotic congenital heart disease or repaired congenital heart disease, with residual shunts or valvular regurgitation at the site of or adjacent to the site of a prosthetic patch or prosthetic device
- Any contraindication for pouch endoscopy
- Subject not being able, according to the Investigator, to reliably meet study requirements, e.g., planned major surgery or travelling during the study, or alcohol/illicit drug dependence |

E.5 End points |
E.5.1 | Primary end point(s) |
• Incidence of treatment-emergent Adverse Events (AEs) and treatment-emergent Adverse Reactions (ARs), i.e., AEs occurring after treatment initiation that are considered to be at least possibly associated with MH002 treatment.
• Laboratory safety parameters: hematology (platelet and RBC count, hemoglobin, hematocrit, WBC count & differential), chemistry (ALT, AST, GGT, LDH, ALP, bilirubin, creatinine, urea, uric acid, albumin, glucose, CRP, total cholesterol, triglycerides, creatin kinase, ionogram (Na, K, Ca, Cl, Phosphate)), urinalysis (blood, protein, glucose, pH (microscopy if clinically indicated)). Clinically significant lab abnormalities will be recorded as AEs |

Visit 1, 2, 3, 4, 5 and 4 Safety follow-up phone calls |
|
E.5.2 | Secondary end point(s) |
• Modified Pouchitis Disease Activity Index (mPDAI) total score, assessing signs and symptoms, and macroscopic appearance of mucosa for inflammation during endoscopy (using Mayo's Stool Frequency scores).
• mPDAI subscores, i.e., endoscopic mucosal appearance, (Mayo) stool frequency, rectal bleeding, fecal urgency/abdominal cramps, fever.
• Total number of ulcerations observed during endoscopy.
• Rate of “clinical response”, defined as a mPDAI total score <5 and a decrease of ≥2 on the mPDAI total score at week 8.
• Rate of “clinical remission”, defined as a mPDAI total score <5, a decrease of ≥2 in mPDAI total score, and a mPDAI endoscopic score <2 at week 8.
• Physician’s Global Assessment (PGA).
• Severity of urgency based on Urgency Scoring Scale (USS) (diary).
• Daily (24h) stool frequency count (diary).
• Blood and fecal inflammatory markers, including CRP, TNF-α, interleukin (IL)-1β, IL-6 and IL-10 in blood and fecal calprotectin.
• Histological assessment of mucosal biopsies using the PDAI histology and Geboes scoring system.
• Differential expression of genes involved in the maintenance of mucosal barrier integrity and those involved in the modulation of inflammation and immunity |
