About this study

Hereditary Haemorrhagic Telangiectasia (HHT) is a rare inherited genetic disease of autosomal dominant inheritance with a prevalence of 1/6000. It is manifested by haemorrhages, mucocutaneous telangiectasias and visceral arteriovenous malformations. These symptoms significantly affect the daily lives of patients, their social relationships and their working lives.

HAS (Haute Autorité de Santé) national recommendations focus on assessing and improving the quality of life (QOL) of patients. Many scales for measuring QOL exist but they are most often general and therefore have the disadvantage of not taking into account the particularities of pathologies and their symptoms and do not allow to have a precise vision of their impact on QOL.

It is important to be able to evaluate this impact, to determine its nature and to quantify it so that health professional can adapt their proposal for the management of HHT patients. And only the development of a specific and validated QOL measurement scale will allow them to access this information.

The aim of this study is to develop a scale of measurement of quality of life in HHT disease and to validate it, a scale specific to HHT, simple and fast to fill by the patients themselves.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Phase 1 : fill out 1 scaleOther

    Patients will be asked to complete questionnaires.

    Group 1: the purpose is to simplify a 75 items scale by a statistical analysis of the data collected from 400 patients. The statistical purification will allow to finalize an abbreviated scale (20-25 items).

    Doctors specialized in Hereditary Haemorrhagic Telangiectasia may suggest that patients enter the study. After submission of the information notice and collection of their non-opposition, patients will have the choice to fill out the paper version or the electronic version of the scale and questionnaires.

  • Phase 2 : fill out 1 scale and 4 questionnairesOther

    Patients will be asked to complete questionnaires.

    Group 2: the purpose is to validate the abbreviated scale by a statistical analysis of the data collected from 200 patients. The statistical validation will allow to check the consistency and correlation of the abbreviated scale with other scales: a general Quality Of Life scale (SF36), an anxiety and depression scale (HAD), a social support scale (SSQ6) and a scale of regulation emotional (CERQ) and to test and re-test to check fidelity of the abbreviated scale.

    Doctors specialized in Hereditary Haemorrhagic Telangiectasia may suggest that patients enter the study. After submission of the information notice and collection of their non-opposition, patients will have the choice to fill out the paper version or the electronic version of the scale and questionnaires.

What is being measured

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

  1. Validity of the factor structure of the developed measurement scale.

    Saturation coefficients of the exploratory factor analysis observed on the sample of 400 participants, confirmatory factor analysis (CFA) adjustment indices on the sample of 200 participants, and factorial weights observed on the AFC will be combined to evaluate the structural validity of the measurement scale.

    Measured: 1 hour

  2. Validity of the reliability of the developed measurement scale.

    Cronbach alphas coefficients, composite reliability values (rho) and percentages of extracted variance will be combined to assess the Reliability of the measurement scale.

    Measured: 1 hour

Questions about this trial

What is this clinical trial studying?

An observational study of Hereditary Hemorrhagic Telangiectasia, run by Hospices Civils de Lyon at 1 site in France.

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 4 inclusion and 1 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 8 Feb 2021. 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 France. 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?

Validity of the factor structure of the developed measurement scale. (time frame: 1 hour). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03695874, which also lists 1 linked publication.

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 8 Feb 2021.
