Exclusion criteria

Exclusion criteria: Subjects not able to give consent ? Subjects without legal capacity who are unable to understand the nature, scope, significance and consequences of this clinical study ? Simultaneous participation in another clinical study or participation in any clinical trial involving an investigational medicinal product or treatment within 30 days prior to beginning of this study ?

Design outcomes

Primary

MeasureTime frame
•Mean Cumulative pain index: AUC of pain scores rated every 4 weeks until death or end of study using numeric rating scale (NRS, 0= no pain, 10 = worst pain) divided by number of multiples of 4 weeks since randomization

Secondary

MeasureTime frame
• Average pain on NRS at 24 weeks • Time until definitive deterioration (TUDD) defined as increase of average pain on NRS of 3 points over baseline sustained over 4 weeks. • Biliary complications defined as cholangitis or post-hepatic cholestasis requiring drainage. • Nutritional status measuring bioimpedance-derived phase angle (BIA) every 12 weeks • Death from any cause • Treatment toxicity according to CTCAE v5.0 • Quality of life (EQ-5D-5L, FACT-Hepatobiliary Symptom Index – FHSI-8)
