Clinical trials

This study will evaluate the efficacy and safety of daridorexant, a dual orexin receptor antagonist, in adults with liver cirrhosis and sleep disturbance, including participants with or without covert hepatic encephalopathy. Sleep disturbance is common in people with liver cirrhosis and may affect quality of life and cognitive function. Participants will be randomly assigned to receive either daridorexant or a matching placebo for 30 days. Neither participants nor study investigators will know which treatment is assigned during the study, except when unblinding is medically necessary. Sleep and cognitive function will be assessed during the study using sleep monitoring, the Psychometric Hepatic Encephalopathy Score (PHES), and the Stroop EncephalApp, together with other clinical and laboratory assessments. The main purpose of the study is to determine whether daridorexant improves sleep efficiency compared with placebo after 30 days. The study will also evaluate changes in sleep quality, sleep structure, cognitive function, the occurrence or improvement of covert hepatic encephalopathy, and the safety of daridorexant. A total of 180 participants are planned to be enrolled at multiple participating hospitals and will be randomly assigned in a 1:1 ratio to daridorexant or placebo.
