PROCESS VALIDATION
CURRENT REGULATORY ASPECTS
2. LIFECYCLE APPROACH OF
PHARMACEUTICAL PROCESS
The lifecycle approach is applied linking product and
process development, validation of the commercial
manufacturing process, and maintenance of the process
in a state of control (continued process verification)
during routine commercial production.

10. PROCESS VALIDATION AND DRUG QUALITY
Effective process validation contributes significantly to assuring
drug quality. The basic principle of quality assurance is that a drug
should be produced that is fit for its intended use. This principle
incorporates the understanding that the following conditions exist:
• Quality, safety, and efficacy are designed or built into the
product.
• Quality cannot be adequately assured merely by in-process and
finished-product inspection or testing.
• Each step of a manufacturing process is controlled to assure
that the finished product meets all quality attributes including
specifications.
9
11. PROCESS VALIDATION DEFINITION
US FDA 1987 definition of PV:
“…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 attributes”
(old definition – Focusing exclusively on the qualification effort without
understanding the process and ensuring the process is maintained in a state of
control may not lead to adequate assurance of quality.)
10
12. FDA PROCESS VALIDATION DEFINITION
“Collection and evaluation of data,
from the process design stage
throughout commercial
production, which establishes
scientific evidence that a
process is capable of
consistently delivering quality
products. Process validation
involves a series of activities
over the lifecycle of the product
and process.”
(FDA Guidance to Industry Jan 24, 2011-Focus
on understanding and data collection as well as
analysis)
US FDA 2011 definition of PV:
11
13. FDA PROCESS VALIDATION GUIDANCE
(General Considerations for Process Validation )
• “Before …commercial distribution to consumers, a
manufacturer should have gained a high degree of assurance
in the performance of the manufacturing
process…consistently produce …”
• Manufacturers should: Understand the sources of variation
• Detect the presence and degree of variation
• Understand the impact of variation on the process and
product attributes
• Control the variation in a manner commensurate with risk
to process and product.”
“…to justify commercial distribution of the product.”
“… use ongoing programs to collect and analyze product
and process data … state if control of the process.”
12
14. FDA PROCESS VALIDATION GUIDANCE
(General Considerations for Process Validation )
• Good project management and good archiving to capture
scientific knowledge.
• Integrated team approach: Process engineering,
industrial pharmacy, analytical chemistry, microbiology,
statistics, manufacturing, and quality assurance.
• Scientific studies throughout the product lifecycle planned,
documented, and approved.
• Greater control over higher-risk attributes.
• Reevaluate risks throughout product/process lifecycle.
• Homogeneity with batch and consistency between
batches are goals of process validation.
13
15. FDA PROCESS VALIDATION GUIDANCE
(Phases of Process Validation)
FDA current thinking on PV revolves around :
• Stage 1 - Process Design -Development
and scale up activities
• Stage 2 - Process Qualification -Demonstrate
reproducible manufacturing through
conformance of PPQ lots
• Stage 3 - Continued Process Verification -
Routine manufacturing and monitoring
of performance
STAGE 1 AND STAGE 3 EMPHASIS – NEW PARADIGM
14
16. STAGE 1, PROCESS DESIGN
(Phases of Process Validation)
Information from product and process development
and scale up activities forms a basis for defining
commercial manufacturing process. It is expected
that manufacturers:
1. Build and capture process knowledge and understanding
2. Establishing a strategy for process control.
15
17. STAGE 1, PROCESS DESIGN
(Phases of Process Validation)
• Defining commercial manufacturing process
• API and excipient pharmaceutics
• Quality attributes
• Variability by different component lots, production operators,
environmental conditions, and measurement systems
• Use risk analysis tools to screen variables
• Define unit operations and process parameters
• Lab scale and pilot scale experiments
• Design of experiments (DoE)
• Identify critical process parameters
• Design space
• Normal operating range
• In-process controls
• Establish a strategy for process control
• Process analytical technology (PAT)

20. QbD EXAMPLE
Assumptions, Literature Review & Prior Knowledge
• API is designated as Amokinol
– Single, neutral polymorph
– Biopharmaceutical Classification System (BCS) class II – low solubility & high
permeability
– API solubility (dissolution) affected by particle size
• Crystallization step impacts particle size
– Degrades by hydrolytic mechanism
• Higher water levels and elevated temperatures will increase degradation
• Degradates are water soluble, so last processing removal point is the aqueous
extraction step
• Degradates are not rejected in the crystallization step
• In vitro-in vivo correlation (IVIVC) established – allows dissolution to be used
as surrogate for clinical performance
• Drug product is oral immediate release tablet

QTPP
20
22. QbD EXAMPLE
Rationale for Formulation & Process Selection
• Amokinol characteristics
– BCS class II (low solubility, high permeability)
– Susceptible to hydrolysis
– 30 mg per tablet (relatively high drug loading)
• Direct compression process selected
– Wet granulation increases risk of hydrolysis of Amokinol
– High drug loading enables content uniformity to be achieved without dry granulati
on operation
– Direct compression is a simple, cost-effective process
• Formulation Design
– Excipient compatibility studies exclude lactose due to API degradation
• Consider particle size aspects of API and excipients
– Dual filler system selected and proportions optimised to give good dissolution and
compression (balance of brittle fracture and plastic deformation consolidation mec
hanisms)
– Conventional non-functional film coat selected based on prior knowledge
21
25. QbD EXAMPLE
• Impact of formulation and process unit operations on Tablet
CQAs assessed using prior knowledge
– Also consider the impact of excipient characteristics on the CQAs

– Test to be performed and acceptance criteria
– Sampling plan – sampling points, number of samples, frequency
– Statistical methods used
– Statistical confidence levels (Process Capability)

information that has bearing on the validity of the
process.
51

–decide on the use of appropriate statistical methods for measuring process
stability and capability
–carry out trending and analysis of process data
–wherever possible, quantitative tools should be used
• Annual Product Review (establish process history based on ongoing process
performance)
• Trend and assess data
• Study OOS and OOT (Out of Trend) data
• Timely monitoring of critical operating and performance parameters.
• Monitor product characteristics, materials, facilities, equipment, and SOP changes
