Skills and Services:

At Trilogy, medical writing is our passion. As specialists in regulatory documentation, we provide a service that is more than just writing. We have been helping pharmaceutical companies of all sizes, worldwide, to streamline their documentation processes for 20 years. Our writers are integral parts of our clients’ teams: proactively planning, coordinating and writing their regulatory documents to meet timelines, with a readability that reduces the time for review and approval.

Our writers are trained to think about the data available and work with the client teams to pull out the messages and present them as clearly as possible, so that a reviewer can quickly find the information they are looking for and easily understand the story to be told. Our approach to writing regulatory documentation ideally results in a minimum of clarifying questions from reviewers, speeding the process of review and ultimately leading to faster approval.
