This editorial discusses the International Committee of Medical Journal Editors’ (ICMJE) proposal to require authors of clinical trials to share de-identified individual patient data (IPD) within six months of publication. While intended to enhance transparency, validate research findings, and expand scientific collaboration, the proposal raises complex ethical, legal, and practical concerns. Supporters argue that IPD sharing enables independent reanalysis, corrects misleading conclusions, and improves evidence-based decision-making, citing past instances where re-evaluation altered drug safety and efficacy assessments. Critics caution against risks such as data misuse, distorted reanalyses, loss of intellectual investment for original researchers, and the potential emergence of “data pirates.” The editorial situates this debate within broader issues of research waste, incomplete publication of clinical trial results, and the need to protect patient confidentiality. Ultimately, the article underscores the importance of establishing fair, secure, and enforceable mechanisms for data sharing. It calls on clinicians to remain vigilant, informed, and engaged as the scientific community navigates the evolving landscape of clinical trial transparency.
