Some of the documents and data contain personal data, including health data, of the persons who participated in the clinical trials. Surrendering these documents to DiaMedica would qualify as a data transfer between joint data controllers under the General Data Protection Regulation (GDPR). DiaMedica has a legimite interest in obtaining documents containing this personal data, but a transfer of personal data to a third country (Diamedica is based outside the European Union) is only allowed where the European Commission has decided that the third country in question ensures an adequate level of protection (Article 45 of the GDPR) or where the controller or processor has provided appropriate safeguards (Article 46 of the GDPR). Currently, there is no EC Decision regarding transfer of personal data to the US and the NCC is not satisfied that protection of the participants’ health data can be guaranteed by providing safeguards. As a consequence the relevant personal data are to remain within the European Union for the time being. Therefore, the NCC orders DiaMedica to designate a representative within the European Union under Article 27 GDPR, where the documents containing the participant’s personal and health data are to be sent.
