Who can take part

You may be able to join if

Male or female participants must be 18 to 75 years of age inclusive, at the time of signing the informed consent.
Participants with a diagnosis of PSC as demonstrated by the presence of the following, and in the absence of apparent causes of secondary sclerosing cholangitis: i) Historical evidence of an elevated ALP >ULN since at least 6 months prior to SV1. ii) Cholangiogram (e.g. magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC) with features compatible with large duct PSC.
ALP ≥1.5x ULN during screening (with variability ≤40% based on two consecutive values). The interval between the two measurements should be of at least 2 weeks (and up to 4 weeks). The baseline value will be the average of all values obtained during screening plus the baseline visit measurement (obtained prior to treatment initiation). • If the mean value of both ALP values is ≥1.5x ULN and the variability between values is ≤40%, the participant is eligible (even if one of the two values is <1.5x ULN). • In cases where one of the two values is >1.5x ULN, but the mean value is <1.5x ULN, or if the variability between values is >40%, an additional value during screening may be obtained at least 2 weeks (and up to 4 weeks) after the previous measurement during screening. • In cases where an additional value is checked, the participant will be eligible if the variability between the second and the third value is ≤ 40%, and the mean value of all ALP values during screening is ≥1.5x ULN. • Once the two consecutive values have been checked as per the above, if the ALP variability for a participant is >40% but ≤45%, and the fluctuations are deemed to be consistent with the historical laboratory values of the participant based on the clinical judgment of the investigator, the participant may be eligible. In this case, the investigator should provide a summary of the case and their assessment in writing to both the CRO’s medical monitor and sponsor’s medical representative for review and sponsor agreement. • In cases of ineligibility, the candidate may be subsequently rescreened at investigator’s discretion as per Section 5.4, and enrolled if stable qualifying values are demonstrated. • All ALP values during screening should be analysed via the central laboratory.
Total bilirubin ≤2.0x ULN at SV1.
If taking UDCA, the participant should have: i) Total daily dose ≤23 mg/kg/day. ii) Minimum of 6 months of stable treatment prior to screening period and expected to remain on stable dose through the 12-week DBP.iii) Minimum of 3 months off treatment prior to screening period if UDCA was recently discontinued.
For participants with IBD: i) Participants with Crohn’s disease must be in remission based on the investigator’s clinical assessment and should be on stable treatment prior to randomisation and during screening. ii) Participants with ulcerative colitis must be in remission or have low activity disease as per the judgement of the investigator and should be on stable treatment prior to randomisation and during screening. iii) Current treatment for IBD is permitted, if the participant has been well controlled for ≥3 months prior to the screening period and is anticipated to remain on a stable dose of drugs for IBD treatment, including biologics, immunosuppressants, immunomodulators, or systemic corticosteroids. This provision regarding stability of IBD treatment applies to the following, among others: • 5-aminosalicylic acid drugs. • Azathioprine; 6-mercaptopurine; methotrexate. • Budesonide (within recommended doses for management of IBD). In addition to oral formulation, topical application of budesonide (rectal foam or enema) is allowed. • Other systemic corticosteroids. • Biologics (e.g. anti-tumour necrosis factor or anti-integrin therapies). • Other immunosuppressants or immunomodulators used for IBD treatment. iv) Participants with IBD should have a colonoscopy performed within two years prior to the screening period showing no evidence of dysplasia or cancer
