OxalEurope keeps the biggest online web-secured database of patients with Primary Hyperoxaluria worldwide, with more than a thousand patients already registered. The OxalEurope Registry (OER) is a result of a collaborative project between partners and their efforts to provide health and wellness to patients suffering from Primary Hyperoxaluria.

The OxalEurope Registry uses Castor Electronic Data Capture system (based in Amsterdam, The Netherlands) as a cloud-based clinical data management platform. Data entry and data collection are accomplished with on-line forms that contain the requisite data fields. The information introduced in this registry follows the General Data Protection Regulation (EU) 2016/679, and has been approved by Ethical Committees at local sites. If you are interested in becoming a participant site for registering data in our database, either as European or non-European partner, you can contact the principal and coordinating sites, which will guide you on the procedure.

Researchers from Academia and Industry are welcome to apply for data access, on an anonymized basis, upon request to the OxalEurope registry board. The application form designated is available below. The OxalEurope registry board will review these proposals and provide feedback in a time frame of two weeks. Send your request to registry@oxaleurope.org. Data access policy of OxalEurope registry is available here.
