Abstract
On 1st of September 2023, the new Federal Act on Data Protection (nFADP) came into force. The revision improves the processing of personal data and grants Swiss citizens new rights. The nFADP applies to all Swiss-based and international companies that provide goods or services to Swiss citizens and to organizations that process sensitive data, such as medical records and genetic material. This short guide shall help you to understand whether the nFADP is relevant for your clinical research project and what the most important changes are as compared to the old FDAP.
