  • Subject narratives, describing individual subject experiences that need an in-depth description, are an important part of properly reporting what happened during a trial, and need to be presented within the Clinical Study Report (CSR).
  • For best readability, narratives should have a common format – concisely laying out the experiences of the particular subjects in an easily comparable manner. But they must also tell the story of each subject’s situation, so a reviewer can adequately assess how the drug may have played a role in the events that took place.
  • Trilogy draws on huge experience in preparing hundreds of subject narratives, and is familiar with the reporting expectations of regulators and the need for consistent presentation.
  • Trilogy writers can work with your clinical teams to develop a format and template for your narratives to ensure they convey key information in an easy to find manner and effectively describe the subject events.
