Pharmaceutical “Quality by Design” (QbD): An Introduction, Process Development and Applications

Quality means fitness for intended use. Pharmaceutical quality refers to product free of contamination and reproducibly delivers the therapeutic benefit promised in the label to the consumer. The Quality of the pharmaceutical product can be evaluated by in vivo or in vitro performance tests.

Quality by design assures in vitro product performance and In vitro product performance provides assurance of in vivo product performance. The pharmaceutical Quality by Design QbD is 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.

Quality by Design QbD is emerging to enhance the assurance of safe, effective drug supply to the consumer, and also offers promise to significantly improve manufacturing quality performance. They are not check-box requirements. Quality by End Product Testing.

Quality by Design. Ex: Manufacturing changes within the approved design space without further regulatory review. While QbD will provide better design predictions, there is also a strong recognition that industrial scale-up and comercial manufacturing experience provides new and very important knowledge about the process and the raw materials used therein.

FDA is aware that knowledge is not static and builds throughout the manufacturing lifecycle. This vigilant and nimble approach is explained by FDA to be essential to best protect the consumer patient. For an NDA, the target product profile is under development while for the ANDA product the target product profile is well established by the labeling and clinical studies conducted to support the approval of the reference product.

USA: Definition The pharmaceutical Quality by Design QbD is 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.

QbD development process include: Begin with a target product profile that describes the use, safety and efficacy of the product Define a target product quality profile that will be used by formulators and process engineers as a quantitative surrogate for aspects of clinical safety and efficacy during product development Gather relevant prior knowledge about the drug substance, potential excipients and process operations into a knowledge space. Use risk assessment to prioritize knowledge gaps for further investigation Design a formulation and identify the critical material quality attributes of the final product that must be controlled to meet the target product quality profile.

Design a manufacturing process to produce a final product having these critical material attributes. Identify the critical process parameters and input raw material attributes that must be controlled to achieve these critical material attributes of the final product. Use risk assessment to prioritize process parameters and material attributes for experimental verification. Combine prior knowledge with experiments to establish a design space or other representation of process understanding.

The control strategy should encompass expected changes in scale and can be guided by a risk assessment. Continually monitor and update the process to assure consistent quality. Less batch failure. More efficient and effective control of change. Additional opportunities: An enhance QbD approach to pharmaceutical development provides opportunities for more flexible regulatory approaches.

Reduction of post-approval submissions. Better innovation due to the ability to improve processes without resubmission to the FDA when remaining in the Design Space. More efficient technology transfer to manufacturing.

Greater regulator confidence of robust products. Risk-based approach and identification. Innovative process validation approaches. Less intense regulatory oversight and less post-approval submissions. For the consumer, greater drug consistency.

More drug availability and less recall. Improved yields, lower cost, less investigations, reduced testing, etc. Time to market reductions: from 12 to 6 years realized by amongst others. First time right: lean assets management. Continuous improvement over the total product life cycle i. Absence of design freeze no variation issues. Less validation burden. Real time controls less batch controls. Realistic risk perceptions. Contributes substantially to realize the better, cheaper and safer mandate.

Implementation of a pilot program to allow manufacturers in the pharmaceutical industry to submit information for a new drug application demonstrating use of QbD principles, product knowledge, and process understanding.

International Conference on Harmonization. Conclusion Ensures robust commercial manufacturing methods for consistent production of quality drugs. Ensures the consumers that therapeutic equivalent generics are manufactured every single time. Offers the agency that quality applications are submitted to improve the review efficiency and to reduce the application approval times.

QbD methodology helps in identifying and justifying target product profiles, product and process understanding. Helps in continuous improvement. There is a need for vigorous and well funded research programs to develop new pharmaceutical manufacturing platforms. Have a question?

This review further clarifies the concept of pharmaceutical quality by design QbD and describes its objectives. QbD elements include the following: 1 a quality target product profile QTPP that identifies the critical quality attributes CQAs of the drug product; 2 product design and understanding including identification of critical material attributes CMAs ; 3 process design and understanding including identification of critical process parameters CPPs , linking CMAs and CPPs to CQAs; 4 a control strategy that includes specifications for the drug substance s , excipient s , and drug product as well as controls for each step of the manufacturing process; and 5 process capability and continual improvement.

Quality by design QbD is a concept first outlined by quality expert Joseph M. Juran in publications, most notably Juran on Quality by Design. While quality by design principles have been used to advance product and process quality in industry, and particularly the automotive industry , they have also been adopted by the U. The Juran Trilogy [2] defines the word "quality" as having two meanings: first, the presence of features that create customer satisfaction; second, the reliability of those features. Failures in features create dissatisfactions, so removing failures is the purpose of quality improvement, while creating features is the purpose of quality by design.

A review on: Applications of pharmaceutical quality by design in product development

Understanding pharmaceutical quality by design.

Она услышала, что в кабине работает вентиляция. Лифт. Почему же не открывается дверца. Вглядевшись, она как в тумане увидела еще одну панель с буквами алфавита от А до Z и тут же вспомнила, что нужно ввести шифр. Клубы дыма начали вытекать из треснувших оконных рам. Сьюзан в отчаянии колотила в дверную панель, но все было бесполезно.

Сохраняя ледяное спокойствие, Сьюзан ткнула указательным пальцем в твердокаменную грудь Хейла и заставила его остановиться. Хейл в шоке отпрянул, поняв, что она не шутит: Сьюзан Флетчер никогда еще до него не дотрагивалась, даже руки не коснулась. Правда, это было не то прикосновение, какое он рисовал в воображении, представляя себе их первый физический контакт, но все же… Хейл долго с изумлением смотрел на нее, затем медленно повернулся и направился к своему терминалу.

Охранник пожал плечами. - Через сорок пять минут. Беккер замахал руками. Ну и порядки. Звук мотора, похожий на визг циркулярной пилы, заставил его повернуться. Парень крупного сложения и прильнувшая к нему сзади девушка въехали на стоянку на стареньком мотоцикле Веспа-250.

Pharmaceutical Quality by Design: Product and Process Development, Understanding, and Control

Кокетка до мозга костей, трижды разведенная, Мидж двигалась по шестикомнатным директорским апартаментам с вызывающей самоуверенностью. Она отличалась острым умом, хорошей интуицией, частенько засиживалась допоздна и, как говорили, знала о внутренних делах АНБ куда больше самого Господа Бога. Черт возьми, - подумал Бринкерхофф, разглядывая ее серое кашемировое платье, - или я старею, или она молодеет. - Еженедельные отчеты.  - Мидж улыбнулась, помахивая пачкой документов.

Он… это кольцо… он совал его нам в лицо, тыкал своими изуродованными пальцами. Он все протягивал к нам руку - чтобы мы взяли кольцо. Я не хотела брать, но мой спутник в конце концов его. А потом этот парень умер.
