To evaluate the efficacy of 3 doses of RhuDex vs placebo for the treatment of PBC in patients with an inadequate response to UDCA.

E.2.2

Secondary objectives of the trial

- To identify efficacious RhuDex dose(s) for the treatment of PBC for further evaluation in phase III
- To study safety and tolerability of RhuDex

E.2.3

Trial contains a sub-study

E.3

Principal inclusion criteria

1. Patient is able to understand the information on the trial and has signed the informed consent form,
2. Male or female patients ≥ 18 and < 75 years,
3. PBC verified by at least 2 out of the following 3 criteria (consistent with The European Association for the Study of the Liver practice guidelines [2017]) :
• Chronic cholestatic disease (e.g. elevated serum alkaline phosphatase [ALP]) of at least 6 months duration,
• Positive anti-mitochondrial antibody titer or presence of PBC-specific antibodies,
• Liver biopsy compatible with the diagnosis of non-cirrhotic PBC,
4. UDCA treatment for at least 6 months (with a stable dose for ≥ 3 months of at least 12 mg/kg/day) prior to baseline and no foreseen changes of the dosing regimen throughout trial participation
5. Inadequate response to UDCA treatment defined by serum ALP levels between 1.5x and 10x the upper limit of normal (ULN) at screening,
6. Women of childbearing potential agree to use during the entire duration of the trial and until 4 weeks following the last dose of trial treatment a highly effective method of birth control, defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptive methods, some intrauterine devices, sexual abstinence, or vasectomised partner. Women of non-childbearing potential (surgically sterile [e.g. hysterectomy, bilateral salpingectomy, bilateral oophorectomy], or postmenopausal with at least 2 years without spontaneous menses) may be included. The investigator is responsible for determining whether the patient uses adequate birth control for trial participation.

E.4

Principal exclusion criteria

- History or presence of other relevant concomitant liver diseases

- Liver cirrhosis

- History or presence of hepatic decompensation (e.g. variceal bleeding hepatic encephalopathy or poorly controlled ascites),

- Serum albumin less than 3.2 g/dL, at screening,

- Any known relevant infectious disease (e.g. active tuberculosis, acquired immunodeficiency syndrome [AIDS]-defining diseases),

- Abnormal renal function (glomerular filtration rate estimated from cystatin C < 60 mL/min) at screening visit,

- Thyroid-stimulating hormone (TSH) > ULN at screening (elevated levels [4.2-10 μU/mL] are acceptable if free thyroxine 4 (fT4) is measured and within the normal range),

- Current history of significant alcohol consumption (> 30 g/day in men, > 20 g/day in women on average) for a period of more than 3 consecutive months within 1 year prior to screening,

- Any illness or medical conditions that are unstable or could jeopardise the safety of the patient and his/her compliance in the trial or might interfere with the trial results,

- Previous and concurrent HIV infection,
- Previous or concurrent cancer except cervical carcinoma in situ, treated basal cell carcinoma, or any cancer curatively treated < 3 years before trial entry,

- Existing or intended pregnancy or breast-feeding.
