The eTMF module is the result of the evolution of traditional paper-format Trial Master Files into electronic format. Using eTMF enables those involved in a project (Sponsors, CROs/laboratory or site Investigators) to simplify the management/input of documents relevant to the clinical trial, thanks to a pre-organized filing structure. Speed and ease of consultation throughout the module from any terminal saves time and lowers costs in storage space and staff, and in editing and maintaining documentation. Security and access to documentation stored in eTMF are guaranteed, thanks to user permissions profiling in the upload, download, and consultation functionalities.
