Trial summary

This Pilot study will enable development \& assessment of a Polycystic Liver Disease-specific patient reported outcomes questionnaire (PLD-Q). Polycystic liver disease (PLD) is characterized by the formation of numerous cysts in the liver, and can lead to severe symptomatic hepatomegaly. Read more about this study

About this study

Official title: Development and Assessment of the Psychometric Properties of a Polycystic Liver Disease-specific Patient Reported Outcomes Questionnaire (PLD-Q).

This Pilot study will enable development \& assessment of a Polycystic Liver Disease-specific patient reported outcomes questionnaire (PLD-Q). Polycystic liver disease (PLD) is characterized by the formation of numerous cysts in the liver, and can lead to severe symptomatic hepatomegaly. It is common in patients with autosomal dominant polycystic liver disease (ADPLD) and autosomal dominant polycystic kidney disease (ADPKD).

Read the detailed description

As liver function is preserved, quality of life is the main outcome in PLD. Patient reported outcomes are increasingly utilized to assess treatment efficacy \& can include any endpoint derived from patient reports \& are usually assessed by questionnaire. Several existing generic questionnaires assess gastrointestinal symptoms, but include irrelevant items for polycystic liver disease (PLD) \& do not examine relevant extra-abdominal symptoms. Also, a questionnaire that assesses the full range of PLD related problems is more likely to be responsive to changes after treatment initiation. Therefore, a tool that accurately detects changes in PLD symptoms is required.

The development and first steps of validation of this questionnaire are already completed in Netherlands. We will further develop this questionnaire for English speaking patients and validate it in Mayo Clinic cohorts.

The study contains three phases. Phase 1: pilot testing of the directly translated questionnaire (from dutch into english) in a small group of polycystic liver disease (PLD) patients. We will include both symptomatic \& asymptomatic patients (i.e. from mild to severe PLD). Phase 2: further refinement of the questionnaire using the results of the pilot test and input of Mayo patient and clinician focus groups. Phase 3: Further validation in a large cohort of 200 PLD patients with (1) comparison with 200 controls without PLD, (2) cross-sectional correlation with total liver (TLV) \& kidney volumes (TKV), (3) comparing ADPKD patients with \& without PLD (5) against other validated questionnaires (e.g. SF36) \& (5) development of a custom "Worry Questionnaire" examining disease-related worries \& concerns. Finally, longitudinal analyses will be performed to assess PLD-Q sensitivity to change in symptoms. Statistical \& psychometric analyses will be provided by Mayo Clinic quality of life Research group, \& developed in accordance with Food and Drug Administration (FDA) guidance on patient-reported outcome measures in consultation with their Study Endpoints \& Labeling Development Division.

Questions about this trial

What is this clinical trial studying?

An observational study of Polycystic Liver Disease, run by Mayo Clinic at 1 site in United States.

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 2 inclusion and 6 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 19 Sep 2024. 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 United States. 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?

Polycystic Liver Disease-specific patient reported outcomes questionnaire (PLD-Q) total score (time frame: baseline to 6 months). 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 19 Sep 2024.
