International Congenital Central Hypoventilation Syndrome (CCHS) REDCap Registry and CCHS Secure Health-hub Advancing Research Efforts

CCHS is a disorder characterized by alveolar hypoventilation with a control of breathing deficit, and symptoms of autonomic nervous system (ANS) dysregulation (ANSD). This study aims to develop a patient registry for CCHS, which will provide crucial insight into disease development, improving outcome in these children through improving early recognition of the disorder, understanding the phenotypic spectrum, and evolution of CCHS natural history. Data will be stored in REDCap (Research Electronic Data Capture) system a secure web application designed exclusively to support data capture for research studies in a secure manner. The REDCap server is hosted securely at Northwestern University, behind a firewall, with virus protection, and using Secure Socket Layer (SSL) authentication to encrypt communication between a user and the server. Protected Health Information (PHI) will be labeled as such in the database and access to it will be restricted to the Principal Investigator (PI) and key personnel participating in the consent process and follow up contact of participants.

Participants in the International CCHS REDCap Registry will be identified and recruited from CAMP's registry of new, current, and past CCHS referrals, including CCHS patients referred for PHOX2B testing and/or consultation. Additionally, patients may also be recruited via the internet using emails, Facebook pages, and mailing lists for family groups. Anyone interested will be offered inclusion into the International CCHS Registry. Participants will be able to participate remotely, from their homes or locations where they have internet, phone, and computer access.

Data collected through the REDCap registry will be de-identified and analyzed. Patients enrolled in this study will be offered participation in CCHS-SHARE and the NIH Global Rare Disease Registry (GRDR). These are both optional parts of the study, and are not required for inclusion. The CCHS-SHARE is a data repository that houses de-identified clinical and registry data on CCHS patients, empowering data sharing across the CCHS research community. The GRDR is established by the NIH Office of Rare Disease Research. The goal of the GRDR is to establish a data repository of de-identified patient data, aggregated in a standardized manner, using Common Data Elements (CDEs) and standardized terminology. De-identification of patient's data will utilize the Global Unique Identifiers (GUID) system. Lurie Children's Hospital will retain ownership of all data shared with CCHS-SHARE and the GRDR. The de-identified data in CCHS-SHARE and GRDR will be available to all investigators to enable analyses across many rare diseases and to facilitate various biomedical studies, including clinical trials, in pursuit of developing drugs and therapeutics to improve the healthcare and the quality of life for the many millions of people who are diagnosed with rare diseases.

Any patient agreeing to be part of CCHS-SHARE and/or GRDR will have their data de-identified and this de-identified data exported and shared with CCHS-SHARE and the GRDR. These participants are also given the option to be contacted for participation in clinical trials. If this option is chosen, any researcher accessing de-identified information through CCHS-SHARE and GRDR and planning to conduct a clinical trial will be allowed to contact the CAMP project coordinator to ask that patients fitting the profile of needed participants be contacted and offered inclusion. No de-identified information will be shared with researchers outside of CAMP, rather the CAMP project coordinator will contact identified patients fitting participation criteria to share contact information and details for the clinical trial. Interested patients will then be given to the option to contact researchers conducting clinical trials at their discretion.
