About this study

Official title: An Observational Study to Evaluate the Efficacy of Nalfurafine Hydrochloride in Patients With Primary Biliary Cholangitis

Nalfurafine hydrochloride is a selective kappa-opioid receptor agonist developed in Japan, and in May 2015 the use of nalfurafine hydrochloride was officially approved in Japan for pruritus in patients with chronic liver diseases including PBC. In the current study, the investigators aimed to assess pruritus and overall QOL before and after administration of nalfurafine hydrochloride in patients with PBC. Furthermore, the investigators took serum sample from the enrolled patients and examine the association of pruritus with possible biomarkers.

Read the detailed description

Primary biliary cholangitis (PBC, formally known as primary biliary cirrhosis) is a chronic cholestatic liver disease. Taking advantage of ursodeoxycholic acid (UDCA), the outcome of patients with PBC has been improved, comparable to those in general population. However, pruritus, which is often a persisting and annoying symptom, may decrease the quality of life (QOL) of patients with PBC. Although anti-histamines are administered for this the efficacy is limited, and no drugs which was clearly proved to be effective for suppressing pruritus have been developed worldwide.

Nalfurafine hydrochloride is a selective kappa-opioid receptor agonist developed in Japan, and in January 2009 approved for pruritus in patients with renal failure and under hemodialysis. A phase 3 trial of nalfurafine hydrochloride for pruritus in patients with chronic liver diseases was completed, indicating the efficacy as well as safety was confirmed. Therefore, in May 2015 the use of nalfurafine hydrochloride was officially approved in Japan for pruritus in patients with chronic liver diseases including PBC. However, only 59 patients with PBC were included and therefore it is still unclear whether nalfurafine chloride is effective in all PBC patients or a part of them, whether the effect of this drug depends on coadministered drugs or other complications, or whether this drug may improve QOL overall in patients with PBC.

In the current study, the investigators aimed to assess pruritus and overall QOL before and after administration of nalfurafine hydrochloride in patients with PBC, to answer the clinical questions described above. Furthermore, the investigators took serum sample from the enrolled patients and examine the association of pruritus with possible biomarkers.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of patients with improvement of pruritus measured by PBC-40

    PBC-40 is a self-report questionnaire for the pruritus as well as health-related QOL in patients with PBC

    Measured: 3 months after administration of nalfurafine

Secondary outcomes (1)
  1. Proportion of patients with improvement of overall health-related QOL measured by PBC-40

    overall HRQOL is measured by SF-36

    Measured: 3 months after administration of nalfurafine

Questions about this trial

What is this clinical trial studying?

An observational study of Primary Biliary Cirrhosis, run by Teikyo University at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients with improvement of pruritus measured by PBC-40 (time frame: 3 months after administration of nalfurafine). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Apr 2018.
