GMP issues in Q assessment

Assessor
6th CPH assessment training workshop,
May 2014
2. 2
Outline
Regulatory strategy- reminder
GMP documentations in Q dossier
Mfg license
GMP certificate
CPP
Dossier documentation that must be QA approved and
signed
Assessor-inspector communication
Possible scenarios
3. 3
Regulatory strategy-
Risk reduction
One does not make sense
without the others!
One assumes that the
others are being met
• assumptions are verified
through the life cycle of
the product
There may be overlaps in
certain aspects e.g.
review/inspection of
process validation data
Post approval
regulatory
activities
Dossier
review Inspection
of mfg,
testing and
clinical sites
Product
Variations, compliant
handling, quality
surveillance,
Vigilance, safety update
etc..
- Readiness for
commercial mfg
- Conformity to
dossier info
- Dossier data
integrity audit
4. 4
GMP documentation in dossiers- provide
minimum basis for review
Manufacturing license
issued by national competent authority
usually certifies that a given site has been
authorized to perform the claimed duties
may or may not specify specific products but at
least the authorized dosage form/line
important to establish the basic legal and
regulatory status of the manufacturer
5. 5
GMP documentation- Contd
GMP certificate
Certifies that a given site has been inspected by
the national inspector (in accordance with local
requirements) and deemed to be of acceptable
compliance.
• Local requirement may make reference to WHO
GMP requirements but does not mean that the
site has been inspected by WHO
In some jurisdictions, GMP certification is part of
the manufacturing license
6. 6
GMP documentation- Contd
Certificate of Pharmaceutical Product
WHO format, comprehensive
issued to a specific formulation
certifies whether the formulation has been reviewed/licensed by the
country of origin and whether it is on the market
includes composition of the approved formulation
states all sites involved in manufacturing of the FPP but may not
state API sites
may include summaries as approved by the issuing agency
• Product information
• Summary of basis of approval (similar to public assessment reports)
7. 7
Certificate of Pharmaceutical Product-contd
Primarily intended to promote faster approval and speedy
access to medicines by helping recipient countries to depend
on sending authorities marketing authorization
Being also used in various other ways
• As a key criteria for registration even though the
application is supported by full dossier data
• As supporting document for tenders
• As a substitute for mfg license and GMP certificates
WHO’s blue book provides recommendations on appropriate
use of CPP in various scenarios
9. 9
Implementation in PQ
Full dossier route SRA route
If available, CPP, should be submitted
- As a minimum, manufacturing license for
the specific sites involved in manufacturing
activities should be submitted
CPP as issued by the reference SRA
should be submitted
Registration or marketing in the country of
origin is not a requirement
- As we are fully reviewing and assuring
the quality, safety/efficacy as well as
compliance of CROs and manufacturing
sites
Registration and marketing in the country
of origin is a requirement
GMP certificate may be submitted to
support the application
- In any case, the site’s compliance status
needs to be confirmed by our inspectors
GMP certificate may be submitted to
support the application
- In any case, the site’s compliance status
needs to be confirmed by our inspectors
10. 10
Documents that must be signed by QA, dated
and/or version tracked
Cover and undertaking letter
Application form- not applicable for PQ except variations and
amendments
Letters of authorization
CEP/API PQ confirmation document
Filled and Blank BMRs
Process validation and stability protocols
Specifications
Commitments
11. 11
Assessor-inspector communication
Via common databases
Easy traceability of all sites related to a given application
Via summary dossier information (QIS)
A quick but critical summary for inspection preparation
Assessment reports and inspection reports
e.g. summarized stability data with assessor’s interpretation
Inspection report from a previous inspection may tell compliance status of a
given QC lab within a manufacturing site
Specific recommendations/feedbacks
Recommendation for inspection of raw data
The need for re-review of bioequivalence data
At the time of PQ
PQ decision form to be signed in by assessment and inspection heads
12. 12
Examples of possible recommendations from
assessors
Instances of unsolicited major changes in QA signed
documentations (e.g. Specs, batch records)
Questions document approval procedure within the company
Instances of failure to investigate OOS or clear OOT results
Indicates a possible breach in quality system
Instances of “never completed” studies
e.g. stability studies that are claimed to have been interrupted
13. 13
Examples- contd
Unaccounted deviations in batch records
Questions reliability of the batch record and the whole quality system
Failure to comply with written commitments
Seen during variation applications
Specific critical steps that may not be immediately visible in
flow charts/method description but considered critical by
assessors
e.g. steps that may involve or result in potential change in polymorph
form
will help inspectors to factor in that in their inspection risk
assessment
14. 14
Example-contd
Inconsistent responses
e.g.- “ we have data” but then fails to provide the data
or they may state “ we do not have data” but then after a while “
we had the data”
“We did that” and after a while “ it was a typo”
Data that looks too good compared to prior experiences
(“surprising results”)
for example, absence/ND levels of a major and common
degradation product
15. 15
Example-contd
Several versions of specifications and BMRs
Matters that may better be resolved by being at the
site
e.g. issues related to media fill validation data
• extent of simulation of interventions
• extent of environmental control
e.g. release assay results close to limit, with no mass balance and
with no other explanation
16. 16
Example-contd
Very similar batch to batch results, as in the case of
dissolution profiles
Too clean trend or too variable data
Unusual large number of rejects
Unusual large number of repeat analysis (BE)
Unaccounted protocol deviations (BE)
Significantly different pK values compared to literature
reported values (BE)
