Study report anonymisation is the removal of patient identifiers from the document and its appendices. It supports MHRA clinical-trial transparency and ICH E6(R2). anonym.plus runs offline and keeps the results narrative readable.
When this applies
A sponsor must share the report after approval. Subject listings and case narratives in the appendices still carry names and dates.
How anonym.plus handles it
- Open the document (PDF or DOCX) in anonym.plus on your machine.
- The tool scans the body and appendices for direct identifiers.
- Local OCR reads any scanned listing or signature page.
- Confirm the flagged names, dates, and centre codes.
- Replace each with a steady token across the whole file.
- Save the cleaned version locally with no upload.
What you need to provide
- The document (PDF, DOCX, or scan).
- An operator: Replace for tokens, Redact for whole listings.
- Optional: a token map for consistent labels across volumes.

Compliance achieved
- Supports sharing under MHRA / ICH E6(R2) transparency requirements.
- Stays offline, so no cloud data-processor contract is needed.
- On-device AES-256-GCM protects the working copy.
- Aligns with UK GDPR Recital 26 when the result no longer identifies anyone.

Limitations & cautions
The appendices are where the risk lives. Patient listings and case narratives hold the most direct identifiers. The tool scans them, but MHRA transparency also wants a documented risk assessment of rare values before you publish.
Frequently asked questions
What is a clinical study report?
It is the full account of a trial’s design, conduct, and results, filed with the MHRA. After approval, the regulator may require sharing. The appendices carry patient-level detail that must be anonymised first.
Which part needs the most attention?
The appendices. Patient listings and individual case narratives hold names, dates, and centre codes. The body text usually holds aggregate figures only.
Will the results still read clearly?
Yes. Efficacy and safety tables stay. Only direct identifiers in listings and narratives are swapped for steady tokens.
