Support for industry on clinical data publication

The European Medicines Agency (EMA) has developed detailed guidance for pharmaceutical companies on the requirements to comply with its policy on the publication of clinical data.

EMA intends to gradually resume clinical data publication from September 2023, having temporarily suspended this activity for all products except .

For more information, see: 

• Clinical data publication
• Clinical Data Publication (Policy 0070) re-launch - EMA webinar

EMA will recommence sending 'invitation letters' to stakeholders and will contact applicants individually prior to the re-launch of clinical data publication.

• External guidance on the implementation of the European Medicines Agency policy on the publication of clinical data for medicinal products for human use

EMA first published guidance in March 2016 and is updating it on a regular basis. Current and past versions of the guidance as well as the list of changes between published versions can be found below:

• External guidance on the implementation of the European Medicines Agency policy on the publication of clinical data for medicinal products for human use

The external guidance provides further information on:

• the scope of the policy as regards clinical reports submitted as part of other regulatory procedures, informed consent applications and duplicate marketing authorisations, as well as definitions (in chapter 1);
• the procedural aspects related to the submission of clinical reports (in chapter 2);
• anonymising clinical reports (in chapter 3), including a template for the anonymisation report (in annex 1.2);
• how to identify and redact commercially confidential information in clinical reports (in chapter 4).

Companies should provide justifications for redactions of commercially confidential information by using the following template:

• Justification table templates

EMA has developed a question-and-answer (Q&A) document to expand on issues addressed in the external guidance and in discussions with applicants. It addresses a number of questions concerning procedural matters including timelines, commercially confidential information and the anonymisation process. For more information, see:

• External guidance on clinical data publication: questions and answers

It will be revised regularly to reflect updates.

EMA held a series of briefings and consultations to support stakeholders in implementing the policy:

Micro, small and medium-sized enterprises (SMEs) are entitled to a free redaction tool license valid for a period of 12 months to allow companies enough time to prepare the final redacted version. The application letter template for the free redaction tool is available in annex 1 of the external guidance.

SMEs should contact the SME office 5 months prior to the CHMP opinion to apply for the free redaction tool license. The SME office can also provide further guidance on the EMA's policy on the publication of clinical data.
