Study summary

Observational study looking at the burden of illness in achondroplasia subjects aged 5-70. The study will include a 5 year review of historical clinical data as well as a single point collection of questionnaire data to look at the impact on the following in individuals with achondroplasia versus a normative population:

  • Quality of life
  • Clinical burden
  • Healthcare resource use
  • Socio-economic burden
  • Psychosocial burden

Up to 300 subjects will be included in sites in Germany, Spain, Italy, Sweden, Austria and Denmark

Read the detailed description

This is a multinational, epidemiological, observational, retrospective, cross-sectional study of individuals with achondroplasia (subjects). This study will be conducted at up to approximately 20 sites in European countries.

Subjects will be invited to enroll via 3 routes:

  1. During routine hospital visits
  2. From subject lists of those previously treated but no longer followed at the study site.
  3. Through collaboration of the Investigator with achondroplasia patient organizations, other achondroplasia-related organizations, other healthcare professionals in their country and achondroplasia-related social media sites. A recruitment flyer will be provided to these organizations, healthcare professionals and social media sites and will to be distributed to potential subjects.

Data will be collected over a minimum of the five years prior to the date of enrolment. Clinical and healthcare resource use data will be collected from medical records. For each subject enrolled, data from medical records will be collected and entered onto an electronic case report form (eCRF) at each site. Data collection from medical records will be supplemented by records provided by the subject and, if necessary, confirmed by the family doctor.

Data about QoL, psychosocial burden, socioeconomic burden and healthcare resource use will be collected via a booklet of validated and structured questionnaires.

Characteristics of subjects with achondroplasia (QoL scores, healthcare resource use, educational level, family status, employment status) will be compared with those of the general population, where available.

As this is an observational study, participation will not affect the subject/Investigator relationship, nor influence Investigator's treatment, therapeutic or other management of the subject.

What researchers measure

Primary outcomes

  1. Healthcare resource use

    Healthcare resource use will be collected from medical records and through patient questionnaires. Data collection from medical records will be supplemented by records provided by the subject and, if necessary, confirmed by the family doctor. Healthcare resource use will be collected via a booklet of validated and structured questionnaires

    Time frame: Once at start of study per subject through completion of questionnaires and via retrospective review of historical data. These will be assessed at interim analysis November 2018 and again at end of study with final Clinical Study Report March 2020

Secondary outcomes

  1. Socio-economic burden (educational, personal, employment and financial impact)

    Data about socio-economic burden will be collected via a booklet of validated and structured questionnaires specifically the Work and Productivity and Activity Impairment (WPAI-SHP)

    Time frame: Outcomes will be collected once at start of study per subject through completion of questionnaires. These will be assessed at interim analysis November 2018 and again at end of study with final Clinical Study Report March 2020

  2. Pediatric Functional Independence Measure (WeeFIM)

    The WeeFIM measures the need for assistance and the severity of disability in children between six months and seven years of age. The instrument consists of 18 items covering three domains: self-care, mobility, and cognition. The mean total score within each domain and the overall total score will be summarized.

    Time frame: Data will be collected once at start of study per subject through completion of questionnaires. These will be assessed at interim analysis November 2018 and again at end of study with final Clinical Study Report March 2020

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 5, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
