Biological Active Substances
Excipients including novel excipients
AS mixed with an excipient unless necessary for the
stability of the active substance e.g. nitroglycerin
Plastic materials

EU ASMF: Principle


Marketing Authorisation Holder (MAH):
Full responsibility for the medicinal product and the
quality and quality control of the active substance
Active Substance Manufacturer (ASM):
Allowance of valuable confidential intellectual property
of know how to be protected


Applicants Part (AP)
Restricted Part (RP)
8
Restricted (confidential) Part



Manufacture
 Detailed description
 Control of Materials
 Control of critical steps and intermediates
 Process Validation
 Manufacturing Process Development
Impurities: for those impurities which do not need to be
controlled in the final active substance and which are related to
detailed description of the manufacturing process.
Justification of specification: for information related to detailed
description of manufacturing process, control of materials and
process validation.

Restricted (confidential) Part (2)

Exceptions

Validation data of sterilisation process may be required
in Applicant’s part when no further sterilisation process
of the final product
10
Procedure - Use




ASMF can only be submitted in relation with a MA
Can also be used when no confidentiality issue between
MAH and ASM
MAA: either CEP or ASM should be submitted
Additional information might be requested from the
Applicant by the Authorities in addition to the ASMF:
e.g. particle size (when not present in a ASMF)
11
Procedure – Use (2)

ASMF holders → Applicant/MA Holder
Copy of latest version of the AP
 Copy of QOS (latest version of AP)
 Letter of access:
Permission of ASMF holder to competent Authorities to
access the data in the ASMF in relation to a specific
application (Annex).

12
Procedure – Use (3)


ASMF holder → Competent Authorities
 The ASMF (applicant + restricted part) either once or
for each MA (depends on national requirements)
 Letter of access
Discussion between ASMs and competent authorities/
EMEA related to ASMF “legally” not possible however
………..
13
General considerations (1)



Responsibility of ASMF holder:
 One identical ASMF in EU for same API (for different
applications in different member states)
 Version number AP MP dossier should be most recent
and identical to version number AP ASMF: responsibility
of the applicant
 Request for harmonisation requested by member states
possible
Update of ASMF
 Responsibility of ASMF holder
 Information to applicant and competent authority
Full supplier chain described in finished product file
14
General considerations (2)




The quality control methods should be kept in line with the
current regulatory and scientific requirements
Compliance with GMP
 Responsibility of Manufacturing Authorisation Holder
(finished product)
MAH can use different QC methods
 full description needed in application file
In case of more than one supplier, there should be one
single compiled specification for each supplier:
responsibility MAH
15
General considerations (3)



MA holder legally bears full responsibility MP on the market
 MA holder also responsible for the active substance
 MA holder cannot share this responsibility with ASMF
 MA holder responsible that active substance from any source is
continuously manufactured and controlled in conformity with MPD
 Thus variations to ASMF can legally only be initiated by MA
holder
 Thus ASMs should continuously inform MA holders of any
changes
New Variation Regulation in EU: Classification guideline not yet
definitively adopted by EU Commission
ASMF holders should precisely know with MA holders are linked to
their ASMFs!
16
Recommendation to API industry




Keep the information the same for all MA-holders
Keep a clear administration of MA holders/countries
connected to a certain ASMF
Inform MA-holders and authorities in case of
variations directly
“As for medicinal products, EDMF holders should
keep the content of their EDMFs updated with respect
to the actual synthesis/manufacturing process”

Conclusion


ASMF: one possibility to submit information on the
API to Competent Authorities
Preferred option of authorities:

CEPs
