What is a Clinical Study Report (CSR)?

A CSR, also referred to as a Clinical Trial Report (CTR), is a comprehensive, integrated document describing the design, conduct, results, and interpretation of a clinical trial, following the guidance provided in ICH E3. It includes clinical and statistical descriptions, tables, figures, and appendices.

When should writing of the CSR begin?

CSR development should begin as soon as clinical data are available, or even earlier, to avoid inefficiencies caused by team members moving on and to prevent retrospective misinterpretation of trial details. Don’t forget you can populate the methodology sections of the CSR template with information from the protocol, statistical analysis plan and other sources before data become available to save time.

What key documents are needed before starting a CSR?

Essential items include the protocol and amendments, the trial procedures manual, the Statistical Analysis Plan (SAP), clinical data tables/figures/listings (TFLs), ethics documentation, and an ICH-compliant CSR template.

What types of CSRs exist and when are they used?

There are four main types:
- Full CSR – required for regulatory submissions and product approval.
- Supplemental CSR – for additional or delayed analyses.
- Abbreviated CSR – for trials not supporting primary efficacy claims.
- Synoptic CSR – acceptable for early safety, discontinued, or limited-scope trials.

Can AI be used to help write a CSR?

Yes—but only for limited, non-interpretive tasks such as formatting, consistency checks, or draft text based strictly on structured sources. AI cannot interpret data, assess safety or efficacy, or replace human authors; full scientific accountability remains with qualified experts.
