ICH Q8- Pharmaceutical Development

Intended to provide a comprehensive understanding of the product and manufacturing process for reviewers and inspectors

Indicates areas where the demonstration of greater understanding of pharmaceutical and manufacturing sciences can create a basis for flexible regulatory approaches

The degree of regulatory flexibility is based on the level of relevant scientific knowledge provided (not the volume of data)


August 6, 2009

ICH Q8- Pharmaceutical Development

Goal: design a quality product and its manufacturing process to consistently deliver the intended performance of the product.

Information and knowledge gained from development studies and manufacturing experience provide:• Scientific understanding to support the

establishment of the design space, specifications, and manufacturing controls.

• Basis for risk management


August 6, 2009

ICH Q8(R1)- Pharmaceutical Development Revisions 1

Pharmaceutical development should include, the following elements:• Defining the target product profile as it relates to Q, S and E• Identifying critical quality attributes (CQAs) of the drug

product, so that those product characteristics having an impact on product quality can be studied and controlled

• Determining the quality attributes of the drug substance, excipients etc. to deliver drug product of the desired quality

• Selecting an appropriate manufacturing process • Identifying a control strategy


August 6, 2009

FDA Challenge to Industry

At the end of the cGMP initiative, the pharmaceutical community has arrived at a crossroad: one path leads towards the desired state* and the other maintains the current state

The path towards the desired state is unfamiliar to many while the current state provides the comfort of predictability

FDA hopes the pharmaceutical industry will choose to move towards the desired state

Approaches to Pharmaceutical Development

Minimal Approach (current)

Development • Mainly empirical• Developmental research often

conducted one variable at a time

Manufacturing Process• Fixed • Validation primarily based on initial

full-scale batches • Focus on optimization and

reproducibility

Enhanced (QbD) Approach (desired)

Development • Systematic, relating mechanistic

understanding of input material attributes and process parameters to drug product CQAs

• Multivariate experiments to understand product and process

• Establishment of design space • PAT tools utilized

Manufacturing Process• Adjustable within design space • Lifecycle approach to validation and,

ideally, continuous process verification

• Focus on control strategy and robustness

• Use of statistical process control methods

ICH Q8(R1)- Appendix 1


August 6, 2009

Benefits of the “Enhanced Approach”

• Post- approval CMC regulatory submissions

• Recalls and manufacturing failures

ICH Q9- Quality Risk Management

Outlines approaches for producing quality pharmaceutical products using science and risk management Intended to provide a practical risk management toolbox implementation of the pharmaceutical development (Q8) and quality systems (Q10)• to evolve a more harmonized and flexible quality oversight processApplies to drug substances, drug products, biological and biotechnological products Supports science-based decision making throughout the product lifecycle• Effective and consistent risk-based decisions

− “Can improve decision making if a quality problem arises”• Regulatory authorities and industry

− Provides regulators with greater assurance of a company’s ability to mitigate potential risks

− Impacts direct regulatory oversight- extent and level


August 6, 2009

ICH Q9- Principles Of Quality Risk ManagementRisk- combination of the probability of occurrence of harmand the severity of that harm

Principles:

• The evaluation of the risk to quality should be based on scientific knowledge and ultimately link to the protection of the patient

• The level of effort, formality, and documentation of the quality risk management process should be commensurate with the level of risk

− Aseptic processing- usually high risk− Stable API with minimal degradation in product formula-

probable low risk for stability

Quality by Design

(QbD)


August 6, 2009

Definitions

Critical Quality Attribute (CQA): A physical, chemical, biological or microbiological property orcharacteristic that should be within an appropriate limit, range, or distribution to ensure the desired product quality

Critical Process Parameter: A process parameter whose variability has an impact on a critical quality attribute and therefore should be monitored or controlled to ensure the process produces the desired quality

Proven Acceptable Range: A characterized range of a process parameter for which operation within this range, while keeping other parameters constant, will result in producing a material meeting relevant quality criteria

Quality by Design: A systematic approach to development that begins with predefined objectives and emphasizes product and process understanding and process control, based on sound science and quality risk management

Real-time release: The ability to evaluate and ensure the acceptable quality of in-process and/or final product based on process data, which typically include a valid combination of assessed material attributes and process controls.



August 6, 2009

Quality by Design is

• Designing and developing a product and associated manufacturing processes that will be used during product development to ensure that the product consistently attains a predefined quality at the end of the manufacturing process

• Quality by design, in conjunction with a quality system, provides a sound framework for the transfer of product knowledge and process understanding from drug development to the commercial manufacturing processes and for post-development changes and optimization

Guidance for Industry: Quality Systems Approach to Pharmaceutical Current Good Manufacturing Practice Regulations Sept 2006

QbD is a systematic approach to development


August 6, 2009

Quality by Design is

“…products and processes that make them are designed in advance to meet their product quality specifications and process control requirements.”“…is based on solid science, valid statistical tools, and sound management techniques that have proven their industrial value for many decades.”This includes:Product profilingExperimental designProcess mappingRisk assessment Automated process controls

Torbeck and Branning BioPharm Int’l May 2009

Goal: to apply these tools in a structured manner


August 6, 2009

Quality by Design Approach

A systematic evaluation, understanding and refining of the formulation and manufacturing process, including: • Identifying, through e.g., prior knowledge, experimentation, and risk

assessment, the material attributes and process parameters that can have an effect on product CQAs

• Determining the functional relationships that link material attributes and process parameters to product CQAs

Using the enhanced process understanding in combination with quality risk management to establish an appropriate control strategy which can, for example, include a proposal for design space(s) and/or real-time release

As a result, this more systematic approach could facilitate continual improvement and innovation throughout the product lifecycle (See ICH Q10 Pharmaceutical Quality System).

QbD Structure

Establishing the relationship between quality attributes and clinical performance

Allows more effective dialogue between industry and regulator during review process*• Shows the connection between Design Space,

Criticality and Control Strategy• Reducing change filings snags

*“PQLI Design Space” ISPE May 2008-John Lepore & James Spavins


August 6, 2009

Regulatory Flexibility: Why?

Facilitate continuous improvement and innovation to improve quality, efficiency, knowledge, and availability

High level of process understanding and control capability can further improve our ability to ensure quality on every batch • compared to a validated process with insufficient

understanding and for which “state of control" is based primarily on compendial testing

August 6, 2009

Regulatory Flexibility: How?

Quality by design• Structured product and process development• Process understanding and control capability• Design space

Integration of prior knowledge and pharmaceutical development into C, M, C submission and review• Present the knowledge gained to provide a more comprehensive

understanding of the product and manufacturing process for reviewers and inspectors

• Risk based assessment and investigations and knowledge sharing (over a product’s life cycle)

Risk Management

• Risk Assessment

• Risk Control

• Risk Communication

• Risk Review

1. What might go wrong?

2. What is the likelihood (probability) it will go wrong?

3. What are the consequences (severity)?

Quality by Design Concept

• Quality cannot be tested into products.

• It has to be built in by design

ICH Q8, Pharmaceutical Development, May 2006

This design incorporates knowledge of the product and the process to ensure all critical quality parameters are adequately controlled.

Barry Cherney, Deputy Director, DTP/OBP/CDER, Oral Presentation, Quality by Design: A Perspective From the Office of Biotechnology Products, PDA Annual Meeting, April 2006


August 6, 2009

“Design Space”

The established range of process parameters that has been demonstrated to provide assurance of quality

Working within the design space is not generally considered as a change of the approved ranges for process parameters…

Movement out of the design space is considered to be a change and would normally initiate a regulatory post-approval change process

ICH Q8, Pharmaceutical Development, May 2006


August 6, 2009

Design Space…

“Is linked to criticality through the results of risk assessment, which differentiates between those product attributes and process parameters that are critical to product quality”

Once Critical Quality Attributes and Critical Process Parameters are identified and understood, they will need to be controlled

“PQLI Design Space” ISPE May 2008-John Lepore & James Spavins


August 6, 2009

A Process is well understood when…

All critical sources of variability are identified and explained

Variability is managed by the process

Product quality attributes can be accurately and reliably predicted over the design space …

The PAT Guidance


August 6, 2009

Process Robustness

• The ability of a process to demonstrate acceptable quality and performance while tolerating variability in inputs

• Requires − Robustness/characterization studies utilizing DoE− Understanding manufacturing capabilities in

development• Enables definition of “design space”


August 6, 2009

Process Robustness/Characterization Studies

These studies provide a further understanding of the relationship between process and product • identify critical parameters• identify limits of each parameter• test to limits• test to failure, where appropriate• results not predefined

Where are we today?

*Early development: Knowledge for QbD is very limited or nonexistent

Licensed products: Knowledge is often limited for many biotech products

Quality by design is NOT quality by control

Quality by design enables rational design• e.g., protein engineering

**The QbD approach is still eyed with caution. Many voiced concerns that they would invest time and resources in a QbD approach and regulators would still rigidly link specifications to clinical experience.

“We have very little experience with QbD, but we are interested in getting some.” Steve Kozlowski, MD, CDER, FDA

QbD Case Study- Regulatory Emphasis & Lifecycle Validation Thinking

A firm recently received an FDA injunction.

Judge’s order: “defendant shall establish and follow scientific product development and manufacturing process design procedures…to control all significant variables, including material attributes and processing parameters, affecting the process materials and final drug product specifications and quality attributes. ”

Demonstration of a firm manufacturing multiple products not in a state of control.

Key is lack of process validation and related issues-• Development, science, technology, use of investigations,

handling deviations, etc.FDA CDER Official ISPE Conference June 2009International Pharmaceutical Quality May/June 2009

ICH Q7A

GMP Guidance for Active Pharmaceutical Ingredients


August 6, 2009

ICH Q7A Objective

Provide guidance regarding good manufacturing practice (GMP) for the manufacturing of active pharmaceutical ingredients (APIs) under an appropriate system for managing quality.

Define manufacturing operations to include:• Receipt of materials• Production• Packaging • Repackaging• Labeling and relabeling• Quality control • Release• Storage• Distribution of APIs and the related controls


August 6, 2009

ICH Q7A- Section 18

SPECIFIC GUIDANCE FOR APIs MANUFACTURED BY CELL CULTURE/FERMENTATION

Covers cell culture, fermentation (CCF), tissue or animal sources including transgenic animals

Early process steps may be subject to GMP but are not covered by Q7A (e.g., cell banking)

Vaccines are not included

Should not use as a stand-alone section


August 6, 2009

ICH Q7A- Section 18: Cell Culture and Fermentation

All previous sections apply to CCF but some issues not in adequate detail

Complexity:• Inherent heterogeneity• Full characterization is difficult• Contamination potential with infectious agents• Sensitivity to subtle or minor process changes

− Changes in the process, facilities or equipment may lead to unexpected product quality

• Manufacturing process contributes to product definition• Process includes facility, equipment, quality of materials


August 6, 2009


Doesn’t cover:• Cell bank creation (ICH Q5D)• Nature of the organism used in manufacturing or

herd maintenance differences• Descriptions of different systems (roller bottles,

fermentors, bioreactors, etc.) transfer methods or monitoring information

• Custom features- inducible or selection systems


August 6, 2009


Greater controls• To prevent (and detect) contamination

− Monitor endotoxin & bioburden for materials and/or process o Manufacturer defines acceptable limits at each stage

− Design adequate ventilation and exhaust systems• For biotechnology products than classical fermentation • For classified environments and EM programs• Validated reprocessing steps• Equipment sterilization between batches (cleaning validation section 12.7)• Water quality (Purified Water or WFI)• Viral removal/inactivation

− Critical steps should be under validated parameters − Pre and post inactivation activities clearly defined (SOPs, equipment,

segregation) − Go to Q5A


August 6, 2009

ICH Q7A- Section 19

APIs FOR USE IN CLINICAL TRIALS

Why is there a special section?• Processes and controls change during

development • Few batches may be identically produced• Batches frequently produced in small non-

commercial scale equipment
