Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age: 18 to 75 years
• A diagnosis of PSC based on cholangiographic evidence of PSC in accordance with American Association for the Study of Liver Diseases (AASLD) guidelines
• ALP >1.5 times the ULN at screening
• PSC with or without IBD, such as ulcerative colitis or Crohn's disease
• If patients are being administered biologic or advanced therapeutic treatments, immunosuppressants, systemic corticosteroids, obeticholic acid, fibrates, or statins, they must be on a stable dose for ≥3 months prior to, and including, Day 0 and plan to remain on a stable dose throughout the study
• If patients are receiving ursodeoxycholic acid, they must be on a stable dose (not exceeding 23 mg/kg/day) for >3 months prior to screening
• Patient agrees to stop all probiotics for at least 2weeks prior to treatment
• Patient is unable to conceive and/or patient who's partner is unable to become pregnant and/or agree to use effective methods of contraception when engaging in heterosexual intercourse

You may not qualify if…

• Treatment with any investigational agents within 3 months or 5 half-lives, whichever is longer prior to treatment or during the study. Gene therapy or other long-lasting investigational agents with unknown half-life is not allowed
• History of a liver transplant or anticipated need for a liver transplant within 1 year
• Patients who show evidence of significant worsening of hepatic function will be excluded.
• Evidence of compensated or decompensated cirrhosis based on histology, relevant medical complications, or laboratory parameters
• Model for end-stage liver disease (MELD) score as below, unless the MELD is driven by anticoagulant therapy, vitamin deficiency, or kidney disease:
• MELD Score of >12 (decompensated cirrhosis) for Part 1 of the study
• MELD Score of >12 for Part 2 of the study
• Small-duct PSC (in the absence of large duct PSC)
• Secondary causes of sclerosing cholangitis including IgG4 associated sclerosing cholangitis
• Any history of cholangiocarcinoma, gallbladder cancer, or hepatocellular carcinoma
• History of any malignancy with lymph node or regional metastases within 5 years or current malignancy undergoing active treatment
• Patients who require chronic use of antibiotics, received antibiotics in the last 1 month, or received Rebyota or Vowst (applicable for patients with Clostridioides difficile infection)
• In patients with ulcerative colitis, partial Mayo score of >6 or, patients with Crohn's disease if CDAI of >220
• Chronic kidney injury
• Recent acute cholangitis (within 90 days)
• Patients with indwelling biliary drain (or stent), total proctocolectomy with ileal anal pouch, partial large bowel resections or history of small bowel resection
• Other causes of liver disease, such as autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), AIH/PSC overlap syndrome, alpha-1-antitrypsin deficiency, viral hepatitis, iron overload syndrome, Wilson disease, nonalcoholic steatohepatitis, and/or alcohol related liver disease. Additionally, positive serology for hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (anti HCV) (detectable HCV RNA in the serum), or human immunodeficiency virus antibodies (anti HIV)
• Active drug (known or suspected use of illicit drugs or drugs of abuse) or alcohol abuse disorder
• Female patients who are pregnant, nursing, or planning to become pregnant during the study
• Clinically significant and/or active infection
• Subjects with a greater degree of immunosuppression, as evidenced by Alsolute neutrophil count <500 cells/mL or in the investigator's judgement immunosuppressed and at higher risk of infection
