EMA Reasons for Rejection of CCI

New data from European Medicines Agency (EMA) confirms the tough position EMA is taking in regard to commercially confidential information (CCI). According to the European Medicines Agency’s “EMA Update on Clinical Data Publication” published on 29 January, 2018, 76% of CCI instances were rejected in 2017. Interestingly, the EMA has provided further insight on how they are considering CCI by citing five reasons for rejection.

EMA Reasons for Rejection of CCI

1. In the public domain

Information is not confidential when already in the public domain or publicly available. Some examples of this include publication on company websites, scientific guidelines, clinical trial registries, scientific literature, and patent applications.

2. No innovative feature

Information that does not bear any innovative features is not considered CCI.

3. Public interest

This reason for rejection pertains to the following types of information that, in the Agency’s view, do not constitute CCI:

  • General or administrative information: names of all CROs and vendors in trial-related duties and functions
  • Some/certain quality related information: temperature, humidity, parameters and storage duration as applied in stability tests
  • Non-Clinical related information: quantification range (lower and upper quantification limits) of pharmacokinetic and pharmacology tests/methods; information concerning a generally-0used/well-known immunohistochemistry method
  • Clinical related information: statistical methods (including imputation methods used for missing data); protocol and protocol amendments.

4. Insufficient justification

If the Agency considers the justification insufficient, then additional clarifications are requested in a justification table. This includes justifications that the Agency finds too vague or not sufficiently specific.

5. Irrelevant justification

If the Agency considers the justification irrelevant, then additional clarifications are requested in a justification table.


The most common EMA reasons for rejection of CCI included ‘insufficient justification,’ which was at least one reason sited on 63% of all instances rejected. This was closely followed by ‘in the public domain,’ which was at least one reason on 50% of all instances rejected.
