For more details and understanding on ASMF read below:

Active Substance Master File (ASMF) or Drug master file (DMF) or CEP is the set of series of information for an Active Pharmaceutical Ingredient (API) or Drug substance brought together in CTD format as per regulatory requirements. ASMF and CEP provide confidential detailed information about facilities, processes, or articles used in the manufacturing, processing, packaging, and storing of one or more human drugs.

CEP is the dossier submitted to EDQM and undergoes review process for its approval before referencing in the MAA.

ASMF are submissions to European regulatory agencies across Europe in all individual countries used to provide confidential, detailed information about facilities, processes, or articles used in the manufacturing, processing, packaging, and storing of human drug products. ASMF is never approved nor disapproved, but is reviewed everytime it is referenced in the MAA application unlike CEP is approved.

ASMF constitutes of two parts, Applicants Part (AP) and Restricted Part (RP).

Applicant’s part has the information on chemistry manufacturing and control (CMC) information of API included in it for the customer reference for its inclusion in its Marketing Authorization Application (MAA) Dossier. Which is further submitted to various European agencies through National, Mutual Recognition Procedure (MRP) or Repeat Use Procedure (RUP) and Decentralized Procedure (DCP) procedures.

Restricted Part alsohas the information on chemistry manufacturing and control (CMC) information of API included in it for the regulatory health authority reference for its evaluation against the Dossier submitted in MAA to various European agencies through National, MRP/RUP and DCP procedures.


  • Allow parties to reference material without disclosing restricted part of ASMF contents to those parties.
  • Are not required by statute or regulation.
  • Are neither approved nor disapproved. Instead, euorpean regulatory health authorities reviews the technical contents of ASMF in connection with the review of MAA that reference them (e.g. All MAA filed under Article 10.1, 10.3, 10.a and so on).
