EU: Quality of Drug Substance in the Dossier –
Revised CPMP Guidelines

 
The revised Note for Guidance on the European Drug Master File Procedure was adopted by CPMP/CVMP in January/February 2004 and came into operation on 31 August this year. What's new compared to the drafted guideline, we commented about on 23 August 2002

Quality of Drug Substance in the dossier for an application of a marketing authorisation

Since 01 July 2003 the harmonised format of the CTD (Common Technical Document) is mandatory in the EU for all types of marketing authorisations irrespective of procedure (national, Mutual Recognition Procedure or centralised) or whether they are based on a full or abridged applicaton.
The CTD is an internationally agreed upon format for the preparation of a presentation for applications to be submitted to the regulatory authorities.

The CTD is organized into 5 modules. Chemical, pharmaceutical and biological documentation is provided by Module 3, the 'Quality Part' that is subdivided into the drug substance ('S') and the drug product ('P') part.

According to the revised Guideline on Summary of Requirements for Active Substances in the Quality Part of the Dossier (CHMP/QWP/297/97 Rev 1 corr - EMEA/CVMP/1069/02) that will be coming into operation on 01 February 2005, there are 4 feasible ways to submit the required information for the drug substance:
2.1 Certificate of Suitability to the Monograph of the European Pharmacopoeia
     (CEP)
2.2 Active Substance Master File (ASMF) Procedure
2.3 Full details of manufacture
2.4 Other supportive data in consideration of the qualification of impurities

Details about the CEP procedures are laid down in Resolution AP-CSP (99) 4. The revised Guideline on Active Substance Master File Procedure (EMEA/CVMP/134/02 - CPMP/QWP/227/02) that is coming into operation on 31 August this year is intended to help applicants for human and veterinary medicinal products, when using the European Drug Master File (EDMF) procedure for active substances in the preparation of a dossier for an application to a marketing authorisation.

Adopted Note for Guidance on the European Drug Master File Procedure

The draft revision of the NfG on the European Drug Master File Procedure (EMEA/CVMP/134-02-CPMP/QWP/227/02-Consultation, February 2002) proposed to make the CEP procedure mandatory for those existing active substances described in the European Pharmacopoeia. This proposal was not agreed upon in the adopted version, where the EDMF procedures can still be used for all active substances, i.e.:

  • New active substances
  • Existing active substances not included in the European Pharmacopoeia (Ph.Eur.) or the pharmacopoeia of an EU Member State
  • Pharmacopoeial active substances included in the Ph.Eur. or in the pharmacopoeia of an EU Member State
  • Additionally, the adopted version clarifies the cases where the EDMF holder may have an EDMF as well as a CEP for a single substance: "(…) Generally, it is however not acceptable that the Applicant/MA holder refers to an EDMF as well as to a CEP for a single active substance of a particular MAA. In cases where the CEP contains too little information (e.g. stability) the Competent Authorities/EMEA may decide that additional information should be provided in the dossier. In such case it may be acceptable to refer both to an EDMF and a CEP (…)"
       

    Recommendation for an ECA Education Course
