Regulatory documents are read by people looking for reasons to ask questions. Good medical writing removes those reasons: every claim is traceable, every number matches, and the story is the same from the summary to the appendix.
Principles that hold across document types
- Write to the template and the guideline that governs the document, such as ICH E3 for clinical study reports.
- Give every statement a source, and keep a source-to-text trace for QC.
- Keep numbers, abbreviations and terminology identical wherever they recur.
- State limitations plainly. Reviewers trust documents that do.
ECP’s writers prepare clinical study reports, investigator brochures, protocol and summary documents, and review existing documents for regulatory readiness.
