CMC-IM working group published a QbD case study on Acetriptan or “ACE Tablets” in 2008. Find out why the FDA, Merck, and Medtronic are using QbDWorks. Therefore, CPPs must be monitored to enable early and accurate detection of deviations outside acceptable limits that will impact product quality. QbD began in order to provide quality drugs to the patients. Parts geometry and tooling geometry are pre-specified and should be a source of variation. QbD Definitions QbD Definitions. This is very good resource! Most QbD case studies typically follow this format: ACE Tablets case study is no exception and follows this outline. The loading rate determines the maximum temperature achieved, and the unloading rate will affect the creation of cracks. Crucially, those measurements should be in real-time. Next step is to link the QTPP – CQA – CPP/CMA through QbD Risk Assessment. I named it,  “ACE Tablet.”. To clearly understand the manufacture processes, FDA generalized Quality by Design (QbD) in the field of pharmacy, which is based on the thorough understanding of how materials and process parameters affect the quality profile of final products. Quality by design (QbD) is a systema c approach to product development that begins with predefined ... (CPP): A CPP of manufacturing process are the parameters which, when changed, can poten ally impact product CQA and may result in failure to meet the limit of the CQA. Ryan, Thanks for your comment! Next step is to link the QTPP – CQA – CPP/CMA through QbD Risk Assessment. Process parameters from Roller compaction are:  Feed Rate, Roller Pressure, Roll Speed, Gap Size, Humidity and API particle size, Magnesium Stearate level, Croscarmellose Sodium. CQAs, CPPs, and CMAs. INTRODUCTION Pharmaceutical industry is constantly searching the ways to ensure and enhance product safety, quality and efficacy. What Matters to Patients? (2012)”. Applying QbD for a legacy product and achieving real time release testing by a design space approach with supportive PAT and soft sensor based models: Challenges in the Implementations . By now we should know the clear difference between QTPP and CQA. The identification of CQAs typically takes place during the first stage of process validation. Another question is whether the development press has the same stiffness as the production press. The aim of PAT testing is to ensure consistent product quality standards while also making the testing process more efficient. 3 4. After initial risk assessment, co-authors select 2 CPP’s: % CV and Moving Window Size. The FDA (US Food and Drug Administration) says the QTPP should also consider the “safety and efficacy” of the product. Post was not sent - check your email addresses! Pharm, sg… If you are not, the OS dependent code in time.cpp will fall back on an inefficient default timer. The end result is a pharmaceutical product that meets predefined quality standards from the start. The critical steps are blending, dry granulation and compression. I summarized the processes in the Lean QbD Software: Uniformity is the main quality attribute for the blending process. You then document these sources of variability as well as determining how you will manage them.

The FDA says CQAs apply to any “physical, chemical, biological, or microbiological property or characteristic” that must be within a limit or range to ensure the pharmaceutical product meets the required quality standard. For those who’d like to take advantage of the ACE Template, you can get it here. Quality by Design for Biotech, Pharmaceutical and Medical Devices. Highlighted with red are the high risk parameters: API, MCC, Relative Humidity, Blender Type, and Number of Revolutions. Of course, not all process parameters are the same as some will have a greater impact on CQAs than others. CQAs are those that impact key aspects of product performance, such as safety, efficacy, and stability. Pharmaceutical quality refers to product free of contamination and reproducibly delivers the therapeutic benefit … QbD and PAT. •Continuous Improvement is the last component of the QbD Process •CPV provides the “feedback” loop in the control of our processes •Process Monitoring and Evaluation Q&A: Containment In Tablet Press Suite 1. Dermot is SL Controls' Compliance Director. Sorry, your blog cannot share posts by email. If problems are detected using the QbT approach, it is usually too late to fix the current batch. •Prioritization in QbD cell line & process development •clone and process selection establishing and justifying analytical program ... (CPP) Parameter of the process that must be maintained in a narrow range to ensure acceptable product quality. CQA is chemical, physical, biological or microbiological properties or characteristics of pharmaceutical product (in-process or finished) that must be within appropriated specifications to ensure quality. This stands for Critical Material Attributes. Quality Target Product Profiles (QTPP) are patient and clinical outcome metrics.

Keywords: Quality by Design (QbD), Target Product Quality Profile (TPQP), Critical Quality Attribute (CQA), Critical Process Parameter (CPP), Quality Risk Management (QRM). Lean QbD is the smartest QbD Risk Assessment tool that connects process parameters to your patients. Critical Quality Attributes (CQA) are  drug product/substance quality metrics. Even to this day, few QbD case studies make this distinction clearly. All the above abbreviations describe steps taken during process validation, all of which are essential in terms of regulatory compliance. While technically working, it does not produce smooth results. Risk Assessment is the backbone of QbD. You can see  the QTPP’s in Lean QbD Risk Assessment template for ACE Tablets below. (2012)”, extracting QTPP’s, CQA’s, CPP’s and CMA’s, Lean QbD Risk Assessment template for ACE Tablets, Immediate Relased Dosage Form Dissolution Testing and Specifications 2015. As a result, it is important to prioritise CPPs over other process parameters as they will have the most impact. Granule Surface Area, Granule Moisture Content, Granule Uniformity of Content are in-process quality attributes. 28-29 January 2014, London, UK This leads to recognize the impact of raw materials (CMA, CPP) on the CQAs and identification and control sources of variability. Next, we go to the process map or process flow diagram. 12345677 Productivity also improves because product quality becomes more consistent which minimises the volume of rejected products. Using Correlation Matrix and FMECA to calculate the risk of Quality Target Product Profile, Critical Quality Attributes, Critical Process Parameters and Critical Material Attributes, the software works in the background so you can focus on what's important - connecting science to patients. Make sure you are building with C++11. Well Controlled CPP . Following blending with extragranular excipients, the manufacturing process utilizes a compression step to produce tablets. It should also include considerations such as purity, stability, and sterility. In the Milling unit operation, CPP are Mill Speed and Screen Size. 10 tablets are packaged into 30cc HDPE bottles containing cotton wadding and a heat-induction seal, closed with polypropylene caps and 6 tablets per blister with push-through foil lidding. Hi Bharka, Lean QbD users have made an oral suspension template for their drug. You then document these sources of variability as well as determining how you will manage them. ####HELP WANTED:#### If anyone can provide an XCode project that's set up to build, that'd be great! Now that we’ve done all of the hard work we can summarize the CPPs and CMAs into the Lean QbD table below. Here’s the summary shot – Processes and the associated CPPs and CMAs nested within each process. I opted for this three-layered approach to incorporating QbD … Joint Regulators/Industry QbD Workshop . Introduction Concepts and Background of QBD Advantages of QBD Objectives of QBD Key Aspects of QBD Significance of QBD Conclusion Reference 2 3. In practice, this means identifying the sources of variability that could possibly affect a process. However, do not underestimate the power required in a Compaction Simulator to create a “knowledge space” for a modern production press. QbD: “A systematic approach to development that begins with predefined objectives and emphasises product and process understanding and process control, based on sound science and quality risk management.” ICH Q8(R1, 2008) PAT is one of the many tools or enablers of QbD. (For more ideas on CQA regarding dissolution on Immediate Release Dosage Forms, See FDA guidances: Immediate Relased Dosage Form Dissolution Testing and Specifications 2015 , Immediate Relased Dosage Form Dissolution Testing and Specifications 1997. Your email address will not be sold or shared with anyone else. The first step of the QbD process was to establish a Quality Target Product Profile (QTPP) for the core tablets. It involves taking measurements of the attributes described in the terms above, i.e. Do you have a case study like this for oral suspension? In the compression process, you have press speed, but the rate of load increase and relaxation, is equally dependent on the press stiffness. Risk Assessment is what links QTPP-CQA-CPP to Control Strategy. A CPP is a variable that can impact the CQA (defined above). According to the FDA, it is essential for “designing, analyzing, and controlling manufacturing”. ... (CPP) are process . It's like the 3D Game Engine, except in C++. Since ACE Tablet case study did not provide QTPP’s, I recommend beginning from the same set from the  the Immediate Release Tablet case study. Implementing QbD calls for identification of both critical quality attributes (CQAs) and critical process parameters (CPPs). If you are willing to share your processes, PAT can be an invaluable tool through life cycle management. The second step was to determine the Critical Quality Attributes (CQA) of the core tablets. Process Parameters for the compression are: Pre-compression force, Compression Force, Press Speed, Die Fill Depth, Feeder Speed, Ejection Force, and Height of Drop. Hi Jose, You can find further info at http://leanqbd.com, Enjoy the QbD Risk Assessment! To organize the information, I will use the Lean QbD software. Continuous Biomanufacturing of Therapeutic Mabs Smaller equipment and facilities More flexible operation Reduced inventory Lower capital costs, less work-in-progress materials Smaller ecological footprint Integrated processing with fewer steps. This second revision, Q8(R2), The compression process flow is as follows. Both these could cause standard problems of phase transformation, fragility, and changes to dissolution. Main attributes associated with this process would be stability.

Followed by Roller Compaction is Milling. This is another aspect of QbD for tablets and is simple to deal with if you are forewarned and have the equipment. ie loading rate = K x (press speed x press stiffness). This is then followed by compression on a rotary tablet press. A CMA relates to input materials and their chemical, physical, biological, or microbiological properties. Excipients include microcrystalline cellulose, lactose monohydrate, croscarmellose sodium, magnesium stearate and talc. As the first step in QbD, if Risk Assessment is not a pleasant experience for the team, you will lose scientists’ support and the QbD momentum may fizzle. Here’s an Input-Process-Output diagram for the compression unit operation. In a QBD approach to manufacturing a pharmaceutical product, you consider the quality of the product at the earliest possible stage rather than simply testing the product for quality towards to the end. Dermot is a validation specialist and has extensive experience leading validation projects for clients in Ireland and internationally, particularly in the multinational pharmaceutical and medical device sectors. Powerpoint TemplatesPage 1Powerpoint TemplatesROLE OF QUALITY BY DESIGN (QbD)IN QUALITY ASSURANCE OFPHARMACEUTICAL PRODUCTPresented by:Dimple lodhaM. CPPs are the process variables that control CQAs during manufacture. For example, Target Product Profile and Quality Attributes were treated as same entities (see Table 1). From knowledge of data process desired attributes may be constructed. (p)CPP, (p)CMA – A process parameter or material 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 (( p) = potential). QbD is an emerging idea which offers pharmaceutical manufacturer with increased self-regulated flexibility while maintaining tight quality standards and real time release of the drug product. Press speed, press stiffness are good parameters to think about for dissolution, etc. We do have internal case studies but it’s not public. ACE Tablets’ QTPP, CQA, CPP, CMA are all here. One of the main QbD tools is statistical Design of Experiments (DoE), which enables to perform the necessary experiments in an efficient and structured way. Martin, Thanks for sharing your compaction experience. This dynamic summary of desired product attributes is used to enhance dialogue between a sponsor and regulatory agencies. In a QBD approach to manufacturing a pharmaceutical product, you consider the quality of the product at the earliest possible stage rather than simply testing the product for quality towards to the end. When I began extracting QTPP’s, CQA’s, CPP’s and CMA’s I noticed that the definitions of QTPP, CQA, CPP, CMA were not well defined. For those who’d like to take advantage of the ACE Template, you can get it here. Pharmaceutical “Quality by Design” (QbD): An Introduction, Process Development and Applications 8 years ago Quality means fitness for intended use. Examples of CPPs include temperature, pH, cooling rate, rotation speed, etc. It establishes the foundation for a quality target product profile (QTPP), which is a summary of a product’s quality characteristics. QULITY – “Quality can not be tested into products; it has to be built in by design” 3 4. Another term often used when determining CPPs and their impact on CQAs is CMA. These quality characteristics are essential to ensure the finished product meets the required standard of quality. This approach ensures the proper identification of the root causes of quality issues. In this article, I will focus on constructing a for a QbD Risk Assessment template by extracting the necessary QTPP, CQA, CPP and CMA. The ACE tablets case study does not mention much about the CPP’s related to the packaging process. Lama Sargi, ANSM . This assessment really depends on the capability of the manufacturing facility and the staff’s knowledge. Quality by Test was the only way to guarantee quality of drug products before FDA launched current Good Manufacturing Practice. Many companies are challenged by Monitoring Critical Process Parameters (CPP) and Critical Quality Attributes (CQA). Manufacturing process involves a pre-blending step, roller compaction of the acetriptan with microcrystalline cellulose, croscarmellose sodium, magnesium stearate and lactose monohydrate, then milling to produce granules before blending with magnesium stearate, and talc. Main quality attribute is the ribbon density and associated CQA is dissolution. There are only two process parameters identified for Lubrication: Revolutions and Fill Volume. Then join our newsletter! Introduction . Now let’s extract QTPP, CQA, CPP and CMA from the ACE Tablets case study. Finally, ACE Tablets’ QTPP, CQA, CPP, CMA are all here. This leads to recognize the impact of raw materials [critical material attributes (CMA), critical process parameters (CPP) on the CQAs and identification and control sources of variability. It is a typical set of 6 unit operations for tablets: (1) Blending, (2) Dry Granulation, (3) Milling, (4) Lubrication, (5) Compression, and (6) Packaging. Cause and Effect or Fishbone Diagram (Figure 11) shows all of the process parameters and variation sources for the blending process. Despite its early QbD days, the approach is similar to the “Quality by Design for ANDAs:An Example for Immediate-Release Dosage Forms. Keywords: QbD, design and development, ICH Q8, Pharmaceutical risk mana gement, DOE. So, what is your opinion on the “ACE Tablets QbD Case study?” How close is it to your QbD approach? The production press will probably be stiffer, therefore more prone to cause process changes. This is the ideal time to establish acceptable limits and ranges as well as establishing protocols for measurement, data collection, and data analysis. Quality-by-Design (QbD) Historical background of Quality-by-Design (QbD) Traditional product development and manufacturing methods are based on a philosophy of Quality-by-Testing (QbT).In QbT, the quality is assessed after the product has been designed and manufactured. In the QbD paradigm, development starts with a target product profile (TPP). we’d be happy to collaborate on making one available. For a complete or nearly complete project, the submission could incorporate QbD metrics (QTPP, CQA, CMA and CPP) and present existing data in the suggested/requested format to facilitate the regulatory review process. How to define “Critical” discussion happens during the Risk Assessment. Where are with QbD US FDA has required sponsors to use QbD in drug development and submissions since January 1, 2013 Typically full-blown QbD is not used in pre- clinical or Phase I stage Often platform technologies available in- house are used, with little or no change in parameters Key aspects of QbD like TPP, CQA and CPP are Do you have a case study for aseptic manufacturing process? The third step incorporated a risk assessment exercise to identify the Critical Processing Parameters (CPP). guidance and describes the principles of quality by design (QbD). We hate spam. Things that are considered when creating a QTPP include the dosage strength, delivery system, dosage form, container system, and more. This assessment really depends on the capability of the manufacturing facility and the staff’s knowledge. However, going through these steps also delivers productivity and efficiency benefits to production lines. DSp – The multidimensional combination and interaction of input variables (e.g., Let me see if they have a publicly shareable version. Of all process parameters, CPPs must be the most rigorously controlled. PAT refers to a method or system of testing. It’s good to test these assumptions at the development stage. Understanding these terms and abbreviations is important given the crucial role process validation plays in relation to compliance, product quality, and production line productivity. In practice, this means identifying the sources of variability that could possibly affect a process. The Q8(R1) document issued in June 2009 includes the Q8 parent guidance and the annex. First, let’s create a new drug profile. He is responsible for the company's quality management systems and maintaining high compliance standards. Also in many cases, the compaction equipment parameters are treated as fixed variables (or noise variables) based on previous products. Under the concept of QbD throughout designing and development of a product, it is essential to define desire product performance profile (TPP, TPQP), Target and identify CQA. This is the process design stage. Let’s continue on with the process map to extract process parameters. Next, we look at the Dry Granulation (Roller Compaction) process. Quality-by-Design (QbD): 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 Critical Quality Parameter (CPP):- a process parameter whose variability has an impact on a critical quality attribute and therefore should be monitored or controlled to … If you are in the generics industry, you should know about the QbD case study on ACE Tablets. Then you can customize from there. ACE tablets are white, biconvex, round tablets containing 20 mg of acetriptan (ACE) with “ACE” and “20” debossed on one side, in cartons containing a blister pack of 6 tablets, or in polypropylene bottles containing 10 tablets. To achieve positive performance testing. No manual handling, increased safety Shorter processing times Increased efficiency This should be documented too. QTPP is a summary of the quality characteristics of a pharmaceutical product. Contribute to BennyQBD/3DEngineCpp development by creating an account on GitHub. Thanks for the case study. This approach ensures the proper identification of the root causes of quality issues. Here’s a summary shot of QTPP’s and CQA’s. Following the roller compaction and milling, the milled granulation is blended with extragranular excipients in a second blending operation. inputs that have a direct and significan t influen ce . However what counts are the details on how they executed each step. Do you know a good QbD case study for Oral Suspension? This should be documented too. The pharmaceutical industry is trying to embrace quality by design (QbD) methodologies provided by the FDA’s process validation (PV) guidance and International Conference on Harmonization (ICH) Q8/Q9/Q10. However I have not seen much focus on getting the right QTPP. Quality Target Product Profile is where everything begins. Want More Tips from QbD Practitioners? Brief introduction on Quality by Design (QbD) Example approach to identify critical quality attributes (CQA) Example approach to identify critical material attributes (CMA) and critical process parameters (CPP) Illustrative examples Concluding remarks 2 There are a lot of terms and abbreviations used when discussing process validation, with some more common than others.
