The Clinical Study Data Request Program's portal collects anonymized clinical trial data from study sponsors and shares this data with participating researchers online. Data is accessed via a password-protected online platform allowing researchers to combine data from different studies, conduct research on the site and download their analyses. Access to the platform is provided for 12 to 24 months. The portal places controls to protect patient-level data and the research participants' privacy and confidentiality. These controls also help ensure the data are used for the agreed research purpose. The portal allows researchers to safely and efficiently access multiple sources of clinical data provided by the portal's partners, helping to advance medical science and improve patient care. It helps ensure data provided by research participants is used to maximum effect in health research.
