Brief summary

The purpose of this study is to assess the safety and efficacy of GKT13783 in patients with Primary Biliary Cholangitis (PBC) who are taking a stable dose of ursodeoxycholic acid (UDCA) treatment, and have persistently high levels of a liver enzyme called Alkaline Phosphatase (ALP).

Detailed description

Primary biliary cholangitis (PBC) is a disease of the liver. It is caused a sustained attack by the body's immune system on the bile ducts (canals) inside the liver. This continuous assault leads to their gradual destruction and eventual disappearance. This results in obstruction to the flow of bile which gets worse with disease progression. Once the bile duct injury has been established, the disease progresses due to ongoing obstruction of bile flow, inflammation and scarring of the liver tissue(fibrosis). The liver eventually fails. This research is looking into whether the study drug is better than a dummy drug when given to patients with PBC. This trial will monitor the patients taking part with regular blood tests and ultrasound liver scans before, during, and at the end of the trial. These measures will allow for the ongoing assessment of liver function, and liver stiffness. It is hoped that in patients in whom the study drug is beneficial, the liver function or stiffness may progress at a slower pace, or may even improve during or at the end of the trial. Liver injury, inflammation and fibrosis Participants will be randomly assigned to 1 of 3 treatment groups (active drug once daily, active drug twice daily or placebo). This is a double blinded study so neither the participants nor the staff responsible for their care will know which group they have been assigned to. During the treatment period, participants will take 4 capsules orally at home in the morning and 4 capsules in the evening for 24 weeks. Participants will be in the trial for 32 weeks in total (about 8 months) and will attend approximately 8 clinic visits.

Masking description

This is a double-blind study: the Sponsor, subjects, investigator staff, persons performing the assessments and data reviewers and statisticians will remain blinded to the identity of the study treatments.

Intervention model description

This will be a double-blind, randomized, placebo-controlled, multicenter, parallel group phase 2 trial. A total of 102 subjects will be randomized and allocated to placebo or one of the 2 active treatment arms, according to a 1:1:1 randomization ratio, stratified at study entry by disease severity defined as baseline serum gamma glutamyl transferase (GGT) \< 2.5 x ULN or ≥ 2.5 x ULN). Accordingly, approximately 34 subjects will be allocated to each of the 3 treatment arms.

Inclusion criteria

1. Male or female aged 18 to 80 years, inclusive. 2. Willing and able to give written informed consent and to comply with the requirements of the study. 3. PBC diagnosis as demonstrated by the presence of ≥ 2 of the following 3 diagnostic factors: * History of elevated ALP levels (\> ULN) for at least 6 months * Positive anti-mitochondrial antibody (AMA) titer or if AMA negative or in low titer (\< 1:80) PBC-specific antibodies (anti-GP210 and/or anti-SP100 and/or antibodies against the major M2 components \[PDC-E2, 2-oxo-glutaric acid dehydrogenase complex\]) * Liver biopsy consistent with PBC (based on historic liver biopsy), including non-suppurative, destructive cholangitis affecting mainly the interlobular and septal bile ducts. 4. Serum ALP ≥ 1.5 x ULN. 5. Serum GGT ≥ 1.5 x ULN. 6. UDCA treatment for at least 6 months and stable dose for at least 3 months prior to Visit 1. 7. Subjects being treated for pruritus with colestyramine must be on a stable dose of colestyramine for at least 8 weeks prior to baseline/Day 1 (Visit 2). Subjects must be willing and able to take colestyramine at least 2 hours before or after study medication. 8. Female subjects of childbearing potential must use a highly effective method of contraception to prevent pregnancy for 4 weeks before randomization and must agree to continue strict contraception for 90 days after last administration of investigational medicinal product (IMP). Male participants with female partners of childbearing potential must be willing to use a condom and require their partner to use an additional form of adequate contraception as approved by the Investigator. This requirement begins at the time of informed consent and ends 90 days after the last administration of IMP. Male study participants must also not donate sperm from baseline until 90 days after the last administration of IMP.

Treatment with any investigational agent within 4 weeks of Visit 1 or 5 half-lives of the investigational medicinal product (whichever is longer). 13. A history of long QT syndrome. 14. Evidence of any of the following cardiac conduction abnormalities during the screening period: * A QTc Fredericia interval \>450 milliseconds for males and \>470 milliseconds for females. * A second or third degree atrioventricular block not successfully treated with a pacemaker. 15. History of cancer in the preceding 5 years, except adequately treated non-melanoma skin cancer, carcinoma in situ of the cervix, in situ prostate cancer, in situ breast ductal carcinoma, or superficial bladder cancer stage 0). 16. The occurrence of any acute infection requiring systemic antibiotic therapy within the 2 weeks prior the Screening Visit (Visit 1), or human immunodeficiency virus (HIV) infection. 17.
