E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This is a Phase 2 study that is divided into 2 parts. Part 1 is an open-label, proof-of-concept study. Part 2 is a multi-center, randomized, double-blind, placebo-controlled, parallel-group study evaluating the efficacy and safety of ustekinumab in subjects with PBC who had an inadequate response to UDCA.
PART 1: Open Label
Primary Objectives:
• To evaluate the efficacy of ustekinumab in reducing alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin in subjects with PBC.
• To determine the ustekinumab regimen(s), based on safety and efficacy, for development in Part 2.
PART 2: Double-blind
Primary Objectives:
• To evaluate the efficacy of ustekinumab in achieving ALP response (a decrease from baseline of > 40% in ALP) in subjects with PBC who had an inadequate response to UCDA.
• To evaluate the safety of ustekinumab in subjects with PBC. |
|
E.2.2 | Secondary objectives of the trial |
PART 2: Double-blind
Secondary Objectives:
• To evaluate the efficacy of ustekinumab in reducing ALP, ALT, AST, and total bilirubin.
• To evaluate improvement in liver fibrosis as measured by the Enhanced Liver Fibrosis (ELF) test.
• To evaluate improvement in liver histology as measured by the modified Hepatic Activity Index (HAI).
• To evaluate the efficacy of ustekinumab in reducing cholestasis as measured by serum bile acid concentrations.
• To evaluate pharmacokinetics, immune response (IR), and pharmacodynamics of ustekinumab.
• To evaluate ustekinumab in improving fatigue, pruritus, and quality of life.
• To evaluate the effect ustekinumab has on long-term disease progression (death, transplant, cirrhosis, doubling of bilirubin). |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Have proven or are likely to have PBC; Be on a stable dose of ursodeoxycholic acid for at least 6 months prior to Week 0;Have screening ALP level > 1.67 ULN; Have screening laboratory test results within protocol-specified limits; Have no history of latent or active TB prior to screening and no signs or symptoms suggestive of active TB upon medical history and/or physical examination. |
|
E.4 | Principal exclusion criteria |
Has history of gastrointestinal bleeding, secondary to portal hypertension, hepatic encephalopathy, or ascites requiring treatment with diuretics; Has a screening direct bilirubin > 1.0 mg/dL; Has a previous liver histology with a diagnosis of steatohepatitis or has a high risk of nonalcoholic steatohepatitis; Has a previous liver histology with a diagnosis of chronic autoimmune hepatitis or has a high risk of autoimmune hepatitis overlap syndrome; Testing positive for surface antigen (HBsAg+), regardless of the results of other hepatitis B tests; Have used colchicine, methotrexate (MTX), azathioprine (AZA), or systemic corticosteroids within 3 months prior to the first administration of study drug. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is ALP response at Week 28 as defined by a decrease from baseline of > 40% in ALP. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
The major secondary endpoints by order of importance are:
1. Modified Corpechot Response at Week 28 as defined by ALP ≤ 3 x ULN, AST ≤ 2 x ULN, total bilirubin ≤ 1 mg/dL for subjects with a total bilirubin ≤ 1 mg/dL at baseline, and > 40% decrease from baseline in ALP. Subjects with total bilirubin >1 mg/dL at baseline will only be considered responders provided that the direct bilirubin value does not increase;
2. Change from baseline in ELF score at Week 28;
3. Change from baseline in the modified HAI at Week 28, in subjects with biopsies;
4. Change from baseline in the total serum bile acid concentrations at Week 28. |
