Pharmaceutical R&D Challenges – especially in bio
“THE fundamental
question is whether
it is still worthwhile
to invest in
pharmaceutical
science”
Drug making is “so crude”, he argues, that
half of all known diseases cannot be
treated at all, and the drugs for the other
half work properly only half the time and
with huge side effects.
“Imagine a car that starts only half
the time, and whose brakes often
don’t work,” he says.
He sees this sorry state of affairs as a huge
business opportunity. In particular, he is
convinced that rapid advances in
diagnostics, genomics and biotechnology
will bring “a brand new revolution” in
personalised medicine.

Quality Target Product Profile (QTPP)
• Summary of the quality characteristics of a drug product to ensure
•
patient safety and efficacy
Includes, but not limited to:
• Dosage form
• Route of administration
• Pharmacokinetic characteristics (e.g. dissolution)
• Quality characteristics for intended use (e.g. sterility, purity)
“Begin with the end in mind”
13
Example of a QTPP elements for a MAb
Ref: A-Mab, ISPE, PQLI 2009
14
CQA – Critical Quality Attribute
• A physical, chemical, biological or microbiological property or
•
•
•
characteristic that should be within an appropriate limit, range, or
distribution to ensure the desired product quality (Q8)
Relates to the finish product (the patient)
Quantifiable – directly (eg assay) or indirectly (eg dissolution)
Examples of CQAs
• Oral solid dosage: Identity (the right API), dose (right active content –
efficacy/safety), purity (safety), dissolution (efficacy)
• mAb
15
Ref: A-Mab, ISPE, PQLI 2009
CPP – Critical Process Parameter
• A process parameter whose
•
•
variability has an impact on a CQA
and therefore should be monitored
or controlled to ensure the process
produces the desired quality (Q8)
CPPs has a direct impact on the
CQAs
A process parameter (PP) can be
measured and controlled
(adjusted)
• Examples of CPPs: temperature,
pressure, compression force,
humidity, rotation speed, addition
rate, flow rate, air shift rate,..
16
Material Attribute
• Material Attribute: A physical,
chemical, biological or
microbiological property or
characteristic of a material that
has a direct impact on the CQA
• A Material Attribute (MA) can
•
be quantified
Typically fixed per batch, but
can sometimes be changed
during processing (eg PSD –
milling)
• Examples of MAs: PSD,
Impurity profile, porosity, mass,
volume, heat capacity, moisture
level, sterility
17
Connection between CQA, MA and CPPs
• The multidimensional combination and interaction of input variables
(e.g., material attributes) and process parameters that have been demonstrated
to provide assurance of quality. (ICH Q8)
• A CQA is dependant on both material attributes and critical process parameters
CQA = f(MA1, MAi, CPP1, CPP2, CPPj)

Control Strategy
• A planned set of controls, derived from current product and process
•
•
•
•
•
•
•
19
understanding, that assures process performance and product quality
The controls can include parameters and attributes related to drug
substance and drug product materials and components, facility and
equipment operating conditions, in-process controls, finished product
specifications, and the associated methods and frequency of monitoring
and control. (ICH Q10)
All products should have a control strategy (in the minimal approach it is
end-product testing)
The control strategy should ensure operation within the design space
The Control Strategy described in Q8 and Q10 is related to CQAs
It can be simple or more advanced
When implemented into manufacturing other controls has to be included
as well, e.g. Control of non-criticals, Operator Heath and Safety
controls, Environmental Controls, Business driver controls, Equipment
controls, Facility controls etc

Integrated functions
• QbD & PAT is a team effort
• Can not be done in silos
• Requires a cross functional teams
• R&D
• Manufacturing
• Process engineer
• Process analyser experience
• Chemometrician
• QA
• QC
• IT
• Regulatory Affaires
• Working differently by combining &
•
28
sharing the different capabilities and
skills within a company
Project organisation must support the
teams
Investing in QbD during development, how can
that pay back during commercial manufacturing?
R&D Savings
• New ways of work
• New skills – also in
manufacturing
• PAT – nice to have on-line
analysers, MVA data analysis
software but a lot can be done
without expensive tools
• More involvement with regulators
upfront
• Software
• No extended time to market
29
Commercial savings
• Secured manufacturability
because of more robust
process
• Supply security
• Higher yield, less scrap
• Reduced cost of qualification
and validation
• Reduced COGS
Will it be mandatory anyway?
Old
“Process validation is establishing
documented evidence which provides a
high degree of assurance that a specific
process will consistently produce a
product meeting its pre-determined
specifications and quality
characteristics”
Process Validation Guide
May, 1987 FDA CDER, CBER, CDRH
30
NEW
“Process validation is the collection
and evaluation of data, from the
process design stage throughout
production, which establishes
scientific evidence that a process is
capable of consistently delivering
quality products.”
Draft Process Validation Guide
Nov, 2008 FDA CDER, CBER

QbD as enabler for e.g. continuous processing technologies
Lower working capital or investment in capital equipment
Common language and QbD tools
Concept also being implemented in Biopharmaceuticals and Vaccine, leveraging
platform technologies

Advanced Monitoring & Control
Use of Multivariate Data Analysis for Process Control
• Traditonal manufacturing
facilities rely on univariate data
visualisation
• Many parameters have to be
observed and interpreted
• Manufacturing is complex and
there is regularly no single
point of failure (2 or more
parameters often compound to
give failure)
• This is reflected in batch
failure rate and variable yields
32
Advanced Monitoring & Control
Use of Multivariate Data Analysis for Process Control
• Multivariate data visualisation
based on process models has
significant advantages
• Multivariate models can assign
single AND compounded
causes to manufacuring
deviations
• Corrective actions can be taken
to save batches and make
consistant quality product
33
Advanced Monitoring & Control
How it works
• Process signatures or ’Golden’ batches
are built using data from previous batches
• These sigantures are simple 2D
representation of many parameters at the
same time
• The multivariate model enables the correct
weight of the parameter
• A process signature with +/-3 SD action
limits can be used in manufacturing
• When an action event is triggered the
multivariate model can be used to find the
1, 2 or more parameters contrubuting to
the deviation
34
Advanced Monitoring & Control
Operability
• 1st Generation
• Used by expert scientists to study batches
• Little or no visibility outside of core
scientific clique
• 2nd Generation
• Plasma screens rolled out to factory floor
• Visibility throughout the facility
