Clinical Study Report (CSR)
A Clinical Study Report (CSR) is the comprehensive scientific document, structured per ICH E3, that describes the conduct, methods, and results of a completed clinical trial and is submitted to regulatory authorities to support marketing applications.
A typical Phase III CSR runs 300; 1,500 pages plus appendices and takes 4; 8 months to author manually. Sponsors writing 10+ CSRs per year face significant medical-writing capacity constraints.
ICH E3 prescribes the CSR's structure, from Synopsis through Discussion to References and Appendices. Modern AI-assisted CSR authoring (Kitsa KScribe) auto-generates the data-driven sections (demographics, disposition, exposure, efficacy, safety tables) directly from SDTM/ADaM datasets, leaving medical writers to focus on interpretation, narrative, and discussion; compressing CSR timelines by 40; 60%.
