Lifetime Impact Study for Achondroplasia

BioMarin Pharmaceutical173 enrolled

Overview

Observational study looking at the burden of illness in achondroplasia subjects aged 3 and above. The study will include a 3 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 175 subjects will be enrolled in sites in Argentina, Colombia and Brazil.

This is a multinational, epidemiological, observational, retrospective, cross-sectional study of individuals with achondroplasia (subjects). This study will be conducted at up to approximately 4 sites in Latin American Countries - Brazil, Argentina and Colombia. Subjects will be identified for participation in the study via three routes: 1. During routine hospital visits 2. From clinic 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 distributed to potential subjects. Data will be collected over a minimum of the three 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, mobility, psychosocial burden, socio-economic 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. Subject participation onto the study will be voluntary, without financial support to the subject.

Outcomes

Primary Outcomes

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 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 end of study with the final Clinical Study Report, May 2020

Secondary Outcomes

Socio-economic burden

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

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. The study will be assessing subjects aged from 3 to 17 years

Adolescent Pediatric Pain Tool (APPT)

The APPT is an instrument for self-reporting of pain by children and adolescents aged 8-17 years. Five subscale scores will be summarized on the analysis population
