Use of clinical study data in medicine evaluation

Clinical study data refer to individual patient data from clinical studies. The European Medicines Agency (EMA) aims to assess whether using clinical study data can help speed up and improve the medicine-evaluation process.

Pilot on using clinical study data in medicine evaluation

Through a proof-of-concept pilot, selected applicants can submit clinical study data to EMA as part of their initial and post-authorisation marketing authorisation applications.

Clinical study data refer to individual patient data from clinical trials. These include:

  • Clinical laboratory results
  • Imaging data
  • Patient medical charts

Currently, applicants are submitting data in an aggregated format as clinical summaries or as individual patient data in PDF listings. This can hinder data analysis and slow down the evaluation process.

In contrast, clinical study data are stored in electronic structured format. This enables regulators to more easily visualise and analyse the data if needed.

The pilot aims to assess whether using clinical study data can help speed up and improve the medicine-evaluation process. The goal of this is to allow patients faster and better informed access to innovative medicines.

EMA launched the pilot in July 2022. It was initially referred to as the 'raw data' pilot.

The pilot is a key activity under the priority recommendations of the former HMA-EMA Big Data Task Force, which has been replaced by the HMA-EMA Big Data Steering Group. It refers to the priority of building network capability to analyse data.

For any queries and to apply to take part in the pilot, write to rawdatapilot@ema.europa.eu.

Pilot extension

EMA and HMA decided to extend the duration of this pilot based on the insights it generated so far. 

As a result, expressions of interest will continue to be accepted until further notice.

Support for pharmaceutical companies

Further information is available to support pharmaceutical companies with their participation in EMA's clinical study data pilot.

The documents include:

  • a questionsandanswers document on the clinical study data pilot;
  • a participation letter to confirm pilot participation for a specific regulatory procedure;
  • a cover letterfor pilot participants to attach to their data packages.

Interim report on using clinical study data in medicine evaluation

An interim report is available on the European medicines regulatory network's experience with analysing patient-level clinical study data submitted voluntarily by marketing authorisation applicants and holders.

This report: 

  • offers preliminary insights into the regulatory benefits of including clinical study data in the marketing authorisation application dossier, potentially leading to earlier opinion and authorisation of medicines;
  • examines the operational and technical practicalities for future systematic submission of clinical study data as part of the marketing authorisation dossier.

It includes experience gained with submission and analysis of patient-level data from clinical studies conducted between September 2022 and December 2023.
