The French Sunshine Act, initially established to promote transparency in healthcare professionals' agreements, has undergone significant interpretation changes by the Directorate General of Health, leading to increased disclosure obligations for foreign companies contracting with French healthcare professionals. A recent decision by the French Supreme Administrative Court expanded these obligations, requiring alignment in reporting for various industries and the disclosure of healthcare professionals' remuneration. Ongoing legal instability and the potential effects on liability and industry participation in drug and device evaluation are critical concerns as further changes to the law are anticipated.
