ICH Q8 Guidance
• Provide guidance on Pharmaceutical Development
• Describe good practice for pharmaceutical product development
• Introduce the concepts of:– Designe Space
– Flexible regulatory approaches
– Quality Risk Management (Q9)

QbD Definition (ICH Q8(R))
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
M. Nebuloni - April 23, 2015
![Page 6: Marino Nebuloni Quality by Design - Federchimica](https://reader030.vdocument.in/reader030/viewer/2022040702/624c34ea2fca703eb258a27f/html5/thumbnails/6.jpg)
Why QbD ?
• High level of assurance of product quality
• Cost saving and efficiency for industry– Increase efficiency of manufacturing process– Minimize/eliminate potential compliance actions– Provide opportunities for continual improvement– Facilitate innovation
• More efficient regulatory oversight– Enhance opportunities for first cycle approval– More focused PAI and post approval cGMP
inspections

Crystallization Development
Strategy
Exploration: Existing Knowledge not sufficient to solve the problem identified.
New knowledge needs to be created and acquired to
contribute to the existing body of knowledge
Exploitation: Utilization of existing knowledge for innovative problem solving

CQAs & CPPs in Crystallization
• Critical Quality Attribute (CQAs)
– A CQA is a physical, chemical, property or characteristic that should be within an appropriate limit, range, or distribution to ensure the desired product quality.
– API Particle Size, Purity, dissolution, polymorphism, stability, ……
• Critical Process Parameter (CPPs)
– A process parameter, e.g. temp, time, speed, when variable it can affect the CQA of a product or process
– Critical Process Parameters (CPP) identified using a risk analysis investigated extensively using a DOE.
• Non-Critical Process Parameters
A process parameter identified as low risk which leads to low probability of product failure

Results of Investigation
Critical Parameters (CQAs) and Process Parameters (CPPs)
to be strectly controlled in the Storage solution before and after filtration:
1. Reduce the solution evaporation (fix the concentration limits-range)
2. Define the filtration temperature
3. Control the filtration time and the presence of crystals traces (< 3 microns) by on line method
4. Control the final pH before the dispensing.
5. Avoid any cooling conditions yhay induces nucleation -definition of Temperature limits

Is QbD really a new concept in
crystallization?
• QbD is not a new concept from the technology perspective
• QbD is new relative to regulatory review and submission
• QbD is optional and should not become a regulatory requirement as agreed to in ICH Q8
• QbD will not necessarily be included in all submissions
• Generation of QbD information during the process phases should be at industry benefict

FDA: What is the advantage of QbD?
Emphasizes product and process understanding and process control

Conclusion
Full implementation of Quality by Design is a
benefit for:
�Manufacturers – less regulatory examination and lower manufacturing costs
�Regulators – less regulatory severity without sacrificing quality
�Patients – increase in availability of high quality pharmaceuticals
