The five key steps of the QbD systematic approach for drug development are as follows:
The QTPP forms the basis of design for the development and should consider the intended clinical use, dosage strength, container closure system, as well as all the drug product quality criteria/attributes appropriate for the intended type of medicine (e.g. dissolution, sterility, purity, stability and drug release).
A CQA is a physical, chemical, biological, or microbiological property that is considered critical to obtain the desired quality profile, and therefore should remain within an appropriate limit, range, or distribution (e.g., disintegration time and dissolution are CQAs for tablets, such as aerodynamic properties and sterility for parenteral and inhaled products, respectively).
CQAs play a pivotal role for product and process development, becoming the reference to identify at an early stage any potential quality issue in the manufacturing and/or control process. In line with ICH Q9 and Q10, CQAs are derived from QTPP and identified by the application of quality risk management through an iterative process, assessing the extent to which their variation can impact the drug product quality profile.
Risk assessment is guided by ICH Q9 and typically performed early in the pharmaceutical development to identify which material attributes and/or process parameters could affect CQAs (e.g., for tablets, the dissolution CQA could be affected by the particle size distribution of the drug substance and/or excipients). The list of potential parameters could be quite extensive, so risk assessment methods are adopted to explore and rank them based on prior knowledge and experimental data. Once identified, they can be further studied to achieve a higher level of process understanding, setting the stage for the establishment of the design space.
The risk assessment and process development experiments (design of experiments) lead to a strong understanding of the linkage and effect of some process parameters/material attributes on product CQAs, enough to identify ranges within which consistent quality can be achieved (i.e., design space ranges). These parameters/attributes can then be selected for inclusion in the design space, and their operating range can vary within the enhanced design space ranges approved by competent authorities without any regulatory action, improving manufacturing flexibility.
As a European-based company with experience in delivering advice and regulatory compliance services for development of pharmaceutical products, ProductLife Group can support you at all stages of the Quality by Design development process, offering strategic advice, resources, and expertise to support drug development as well as regulatory/CMC submissions.
