Quality: A New ParadigmM iMain message

Science is no longer isolated; it is living across the lifecycle

of the product/process within a Quality Management System

Quality: A New Paradigm

The new paradigm emphasizes:

1. Quality must be mainly built in during pharmaceutical development and it will not only improve by additional testing

2. Better utilization of modern science throughout product lifecycle

3. Quality Risk Management is a key enabler throughout product lifecycle

4 Robust Pharmaceutical Quality System with appropriate knowledge4. Robust Pharmaceutical Quality System with appropriate knowledge management, assures quality throughout product life cycle

5. An integrated approach to development, manufacturing and quality for both g pp p , g q yindustry and regulators

ICH guidelines: Q8 Pharmaceutical DevelopmentExample QbD Approach

Quality Target Product Profile (QTPP)

Determine “potential” critical quality attributes (CQAs)

Link raw material attributes and process parameters to CQAs and perform risk assessment

Develop a design space (optional and not required)

Design and implement a control strategy (relate CQAs and Critical Processing Parameters)

Manage product lifecycle, including continual improvement

Quality by designSome definitions

_ Quality Target Product Profile (QTPP): the critical quality attributes to be achieved by the product to meet the needs of the intended end use.

Ri k t id tif i t i l tt ib t d t_Risk assessment: identifying material attributes and process parameters as CQAs and CPPs (by means of Failure Mode Effects Analysis or other tools).

_Critical Quality Attribute (CQA): the quality of ingredients and intermediates required to assure the Quality Target Product Profile

_Critical Process Parameter (CPP): the process parameters required to assure the Quality Target Product Profile

- The contents of ICH Q8 Pharmaceutical Development is reflectedThe contents of ICH Q8 Pharmaceutical Development is reflected in the CTD chapter 2

- ICHQ9 and Q8 are strongly linked to enable a risk-based approach to development (in addition to science based)

However, some points are not clarified yet:

- How to integrate the post-approval phase with Continuous Verification & Improvement in the CTD (i.e. control strategy with IPCs and release

testing might change)?
