Understanding the Spectrum of ENPP1 Deficiency and Acute ABCC6 Deficiency

Inozyme Pharma38 enrolled

Overview

To date, the investigators lack characterization of, the burden of, and the systemic progression of disease in ENPP1 deficiency and ABCC6 deficiency from a patient and/or parent perspective. This study aims to document this characterization, progression as well as the burden of disease. Link to the study registration- https://www.engagehealth.com/survey/TakeSurvey.aspx?SurveyID=8252n62

This will be a comprehensive, cross-sectional study conducted in approximately 60 individuals (or representative parents of patients) affected by ENPP1 deficiency and the acute form of ABCC6 deficiency. All study participants will complete the RSVP, PRO tools and upload a proof of disease form, followed by an interview conducted by a trained interviewer. It is estimated that each respondent will need up to 60 minutes for the entire process; 20 minutes to complete the RSVP, PRO tools and to upload proof of diagnosis of ENPP1 deficiency or the acute form of ABBC6 deficiency, and approximately 40 minutes to complete the interview and address any follow-up questions if needed.

Outcomes

Primary Outcomes

To improve the understanding of the characterization and burden of disease in ENPP1 deficient, and acute ABCC6 deficient, patients who are still growing and those who are done growing

The burden of disease through the eyes/voice of the patient and or caregiver will be collected and analyze for improved understanding

Time frame: Data will be collected during a 45 minute interview. This will be a patient or parent report of events that occurred from birth to the patient's current age which will differ for all respondents.

To collect information regarding disease burden, in the patient's / families own terms

Data will be collected in terms used by the patient and or caregiver

To build a foundation of evidence to contribute to the dossier, used for many purposes, including reimbursement and regulatory bodies.

Data will be collected and analyzed to be able to draw meaningful conclusions regarding burden of disease in the voice of patients and caregivers
