Skills and Services:

At Trilogy, medical writing is our passion. As specialists in clinical regulatory documentation, we provide a service that is more than just writing. Our writers are integral parts of our clients’ teams: proactively planning, coordinating and writing their clinical documents to meet timelines, with a readability that reduces the time for review and approval. We have been helping pharmaceutical companies and clinical research organizations of all sizes, worldwide, to streamline their documentation processes for over 15 years – either as support on a one-off document or the entire clinical development programme.

We provide our clients with a constructive advice on their projects: we guide our clients’ teams through the writing process and ask them the right questions in order to produce documents that communicate effectively. Our writers are trained to understand that our job is not to produce a data dump: it is to think about the data available and work with the team 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 clinical documentation ideally results in a minimum of clarifying questions from reviewers, speeding the process of review and ultimately leading to faster approval.

Trilogy currently has more than 40 writers, who are located in Trilogy’s 3 offices: Frankfurt in Germany (HQ), Cambridge in the UK, and Durham, North Carolina in the US. We pride ourselves on our “dedicated team” approach when developing documents, which greatly reduces the time needed for production and ensures much greater levels of continuity throughout an entire development programme.
