A Case Study in Application of the Risk Knowledge Infinity Cycle.

The Risk Knowledge Infinity (RKI) Cycle Framework was featured as part of the ICH-sanctioned training materials supporting the recent issuance of ICH Q9(R1) Quality Risk Management To support ICH Q9(R1) understanding and adoption, this paper presents a case study on the application of the RKI Cycle, based on an underlying out-of-specification investigation. This case study provides a stepwise walk-through of the cycle to illustrate how key concepts within the ICH Q9(R1) revision can be achieved through better connecting quality risk management and knowledge management with a framework such as the RKI Cycle.

A comprehensive quality control and cost comparison study of branded and generic angiotensin receptor blockers.

This study was designed to assess both the quality and cost aspects of various branded and generic formulations of angiotensin receptor blockers, specifically Irbesartan, Losartan Potassium, Olmesartan Medoxomil, Telmisartan, and Valsartan. The collected samples underwent distinct quality evaluations using the methods outlined in different global Pharmacopoeias (British Pharmacopoeia/European Pharmacopoeia, Indian Pharmacopoeia and United States Pharmacopoeia). These drugs were characterized using Fourier-Transform Infrared Spectroscopy and Nuclear Magnetic Resonance techniques, while their quality and concentration were analysed using High Performance Liquid Chromatography. The release profile of the drugs was examined through dissolution testing. Additionally, a cost comparison analysis was carried out by determining the prevailing market prices of the drugs. The evaluated branded and generic angiotensin receptor blockers were found to meet the established standards for impurities, active drug content, and dissolution as set by these Pharmacopoeias, indicating their optimal quality. Notably, the generic drugs exhibited significantly lower costs compared to their branded counterparts. This study confirms that the quality of generic angiotensin receptor blockers is equivalent to that of their branded counterparts. Consequently, these findings support the practicality of utilizing generic drugs as a more economically sustainable and cost-effective approach to managing diseases, especially those of chronic nature.

Design, Characterization, and Bioanalytical Applications of Green Terbium- and Nitrogen-Doped Carbon Quantum Dots as a Fluorescent Nanoprobe for Omadacycline Analysis.

Terbium- and nitrogen-doped carbon quantum dots (Tb,N@CQDs) were greenly created employing microwave synthesis from plum juice with terbium nitrate. The synthesis of Tb,N@CQDs was fast (7 min) with a high quantum yield (35.44%). Tb,N@CQDs were fully characterized using transmission electron microscopy, Zeta potential analysis, fluorescence, and ultraviolet spectroscopy. Omadacycline (OMC) is a broad-spectrum tetracycline that has been recently approved by the United States Food and Drug Act (FDA) in October 2018. OMC is the first oral aminomethylcycline class antibiotic drug that was authorized for the treatment of acute skin structure infections and community-acquired pneumonia. Tb,N@CQDs exhibited emission at 440 nm after excitation at 360 nm, where their fluorescence intensity showed a reduction upon addition of OMC. The experimental parameters were further studied and optimized. The linear range was between 40 and 60 parts per billion (ppb), with (limit of quantitation) equal to 34.78 ppb. The proposed approach was validated for bioanalytical purposes using FDA guidelines and proved to be straightforward, cheap, highly sensitive, and very selective, which can be used in clinical studies. The developed approach proved to be green using some current assessment metrics and was applied successfully for the determination of OMC in human plasma, milk, and pharmaceutical formulations as well as pharmacokinetic study.

Creating an Assessment Indicator of Quality Culture Development in the Generic Pharmaceutical Industry in Japan.

In the past few years, there have been several instances of illicit pharmaceutical manufacturing in Japan, and there is a growing awareness of the importance of corporate compliance and pharmaceutical manufacturing and quality controls. One cause of illicit manufacturing is the inadequate development of quality culture. This study focuses on the degree of quality culture development in Japanese pharmaceutical companies manufacturing generic drugs. Because no evaluation index for Japan can visualize the degree of quality culture development in each company, this study sought to establish this index to utilize it as a tool for evaluating the degree of quality culture development that would enable each company to continuously monitor and improve its own. We conducted a questionnaire survey among Japan Generic Medicines Association members to evaluate the degree of their quality culture development. The questionnaire contained 28 questions in five evaluation categories. Potential indicators of quality culture development included "Employee growth and satisfaction"; "Management commitment"; "Improvement activities"; "Communication"; and "Environment, health, and safety." We obtained 294 responses from 37 Marketing Authorization Holder (MAH) and 61 manufacturing sites. Respondents were classified by roles of management, manager, and nonmanager. The results confirmed the current status of quality culture development efforts, showing that important messages such as the corporate philosophy as communicated by the management is well known, awareness of quality culture development level differs by role, and appropriate resources are not adequately allocated to employees or facilities. Based on the results, use of the index of quality culture development helped to make relative comparisons and visualize the areas to be addressed for quality culture development. This study established and visualized the index for the degree of quality culture development in domestic generic drug manufacturing companies and we hope this indicator becomes a useful tool for evaluating a company's quality culture development level.

3BP-3940, a highly potent FAP-targeting peptide for theranostics - production, validation and first in human experience with Ga-68 and Lu-177.

Hardly any new tracers attracted more attention in nuclear medicine in the last couple of years than radiolabeled fibroblast activation protein inhibitors (FAPi's). Molecules targeting cancer-associated fibroblasts (CAFs) or disease-associated fibroblasts in benign disorders (DAFs) gave rise to a new class of radiopharmaceuticals widely applicable for imaging and with the desired use as therapeutic compounds. Despite displaying benefits in diagnostic sensitivity over FDG, most FAP-targeting compounds in today's clinical routine continue to lack therapeutic utility due to short tumor retention. In this study, we evaluated 3BP-3940, specifically designed for achieving prolonged tumor retention and remarkably low uptake in healthy tissues. We herein present the automated manufacturing of gallium-68 (Ga-68) and lutetium-177 (Lu-177)-labeled 3BP-3940, their respective in vitro stability, validation of an automated production process, and validation of an analytical HPLC method for quality control. Finally, we give a first insight into the clinical utility of the two compounds.

Quality of New Domestic Hand Sanitizer Drug Product Manufacturers During COVID-19.

The FDA initiated a cross-sectional, statistically based sampling and testing study to characterize the quality of marketed alcohol-based hand sanitizer (ABHS) by evaluating the alcohol content and impurities present in ABHS products manufactured by establishments that registered with the FDA during March-April 2020. A stratified sampling design divided the population of manufacturers into independent groups based on each establishment's level of experience with FDA oversight and its geographic location. ABHS products were collected and analyzed by spatially offset Raman spectroscopy and gas chromatography with mass spectrometry (GC-MS). The GC-MS results for 310 products, from 196 newly registered domestic manufacturers, showed that 71.6% (± 5.7%) of these manufacturers had violative products. In 104 (33.5%) cases, the alcohol content did not meet label claim assay specifications but still fell within CDC efficacy ranges. Ethanol ABHS products failed more often overall (assay and impurities) (84.3%) and for impurities (84.3%), than isopropanol ABHS products (11.2% and 6.2%, respectively). Differences in test results across active ingredients were statistically significant. Ethanol ABHS products often (63.5% of cases) failed due to the presence of acetal or acetaldehyde, particularly in products with pH ≤ 6. Other impurities were also detected in several ABHS products, suggesting the use of low-grade alcohol in the manufacture of these products. Evidence was insufficient to conclude that having experience manufacturing FDA-regulated products, or lack thereof, influenced product-level violative results. This study highlights the importance of sourcing and testing active pharmaceutical ingredients to produce quality drug products.

Real-time algorithmic exchange and processing of pharmaceutical quality data and information.

Herein, a modern method is proposed for exchanging and processing real-time medicinal product information using Health Level 7 International's (HL7) Fast Healthcare Interoperability Resources (FHIR®) standard, Application Programming Interfaces (API), digitization and artificial intelligence. FHIR is presently in use largely to facilitate interactions between patient-facing healthcare institutions, such as hospitals, doctor's offices, and laboratories, for electronic health record management and exchange. There are several ongoing efforts to adapt the FHIR standard for regulatory use cases to support the needs of the global biopharmaceutical industry, including the exchange of Electronic Product Information (ePI); chemistry, manufacturing, and controls (CMC) data; and adverse event reporting. Once in place, this new method of data exchange is expected to (1) improve efficiency by reducing the time and effort needed to manage regulatory information; (2) accelerate decision making; (3) encourage innovation in pharmaceutical manufacturing; (4) improve the ability and agility of information exchange. Currently, the end-to-end timescale for the pharmaceutical regulatory workflow is measured in months and years. This new paradigm will use FHIR APIs and other supporting technologies to reduce the potential time for data exchange from months to days, hours, minutes, and eventually sub-seconds. With such drastic improvements in speed provided by digitization, automation, and interoperability, the biopharmaceutical industry can reach more patients, and more quickly than at any time in the industry's 100+ year history. The present work will focus on examining specific real-world implementation examples for using FHIR to support exchange of CMC information within and across the biopharmaceutical industry.

Quality Culture and Knowledge Management in the Japanese Pharmaceutical Industry-A Cross-Sectional Study and Case Report.

In the past few years, there have been several instances of illicit pharmaceutical manufacturing in Japan. Insufficient good manufacturing practice compliance and lack of quality culture in some pharmaceutical companies have been suggested as the underlying reasons for such cases. We aimed to focus on knowledge management and fostering of quality culture in pharmaceutical companies in Japan to understand their current situation and find a strategy for the availability of high-quality reliable pharmaceutical products. A wide-ranging questionnaire survey was conducted to understand the issues related to knowledge management and fostering of quality culture across pharmaceutical companies in Japan. A published investigation report on an illicit manufacturing case was closely examined by organizing the available facts using the diagram. Based on 395 responses to the questionnaire survey, we found that although pharmaceutical companies understand the importance of knowledge management and quality culture, issues exist in their operational methods. A total of 94% of the respondents agreed that they mentioned "knowledge management" as an enabler of the Pharmaceutical Quality System of ICH Q10, and 98% of the respondents accepted that insufficient fostering of quality culture leads to corporate risk. However, the survey revealed that many companies are struggling with this approach. Based on a report on an illicit manufacturing case, we analyzed the direct causes of misconduct and prepared a systematic summary that can be easily comprehended. Comparison of the illicit manufacturing case report with our questionnaire results suggests that many pharmaceutical companies do not regard the misconduct case as a situation that could occur in their company. With the revision of the Pharmaceuticals and Medical Devices Act and good manufacturing practice Ministerial Ordinance, we advocate the need for all employees of pharmaceutical companies to reconsider the priorities of their companies from the patient perspective.

Development and Validation of Green and High-Throughput Microwell Spectrophotometric Assay for the Determination of Selective Serotonin Reuptake Inhibitors in Their Pharmaceutical Dosage Forms.

This study describes the development and validation of a new green and high-throughput microwell spectrophotometric assay (MW-SPA) for the determination of three selective serotonin reuptake inhibitors (SSRIs) in their pharmaceutical dosage forms. These SSRIs are fluoxetine, fluvoxamine, and paroxetine, the most prescribed drugs for the treatment of depression. The proposed assay was based on the formation of orange-colored N-substituted naphthoquinone derivatives upon the reaction of SSRIs with 1,2-naphthoquinone-4-sulphonate (NQS) in alkaline media. The assay was conducted in 96-microwell assay plates, and the absorbances of the reaction products were measured by a microplate reader at their maximum absorbance wavelengths. The optimum conditions of the reaction were refined and established. Under these conditions, calibration curves were generated, and linear regression equations were computed. The linear relations between the absorbances and drug concentrations were linear with good correlation coefficients (0.9992-0.9997) in the range of 2-80 µg/mL. The assay limits of detection were in the range of 1.5-4.2 µg/mL. The precision was satisfactory as the values of relative standard deviation did not exceed 1.70%. The accuracy of the assay was ≥98.2%. The proposed MW-SPA was successfully applied to the analysis of the SSRIs in their pharmaceutical dosage forms with acceptable accuracy and precision; the label claims were 99.2-100.5% (±0.96-1.35%). The results of the proposed MW-SPA were compared with those of the official/pre-validated assays by statistical analysis with respect to the accuracy (by t-test) and precision (by F-test). No significant differences were found between the calculated and theoretical values of the t- and F-tests at the 95% confidence level, proving similar accuracy and precision in the determination of SSRIs by both assays. The greenness of the proposed assay was confirmed by two metric tools. In addition, the assay is characterized with a high-throughput property which enables the simultaneous analysis of many samples in a short time. Therefore, the assay is a valuable tool for rapid routine application in pharmaceutical quality control units for the determination of the investigated SSRIs.

An Adequate Pharmaceutical Quality System for Personalized Preparation.

The pharmacy compounding of personalized preparations has evolved a great deal, and with it, the way of working and the legal requirements have also evolved. An adequate pharmaceutical quality system for personalized preparations presents fundamental differences with respect to the system designed for industrial medicines since the size, complexity, and characteristics of the activity of the manufacturing laboratory and the applications and uses of the manufactured medicines must be taken into account. Legislation must advance and adapt to the needs of personalized preparations, filling the deficiencies currently found in this field. The limitations of personalized preparation in its pharmaceutical quality system are analysed and a method based on a proficiency testing program specially designed to overcome these limitations is proposed: the Personalized Preparation Quality Assurance Program (PACMI). This method makes it possible to expand the samples and destructive tests, and dedicate more resources, facilities, and equipment. It allows for more in-depth knowledge of the product and the processes used, and for proposed improvements that increase the overall quality for improved patient health. PACMI introduces tools used in risk management in order to guarantee the quality of an essentially heterogeneous service: personalized preparation.

Regulatory Experiences with Root Causes and Risk Factors for Nitrosamine Impurities in Pharmaceuticals.

N-Nitrosamines (also referred to as nitrosamines) are a class of substances, many of which are highly potent mutagenic agents which have been classified as probable human carcinogens. Nitrosamine impurities have been a concern within the pharmaceutical industry and by regulatory authorities worldwide since June 2018, when regulators were informed of the presence of N-nitrosodimethylamine (NDMA) in the angiotensin-II receptor blocker (ARB) medicine, valsartan.  Since that time, regulatory authorities have collaborated to share information and knowledge on issues related to nitrosamines with a goal of promoting convergence on technical issues and reducing and mitigating patient exposure to harmful nitrosamine impurities in human drug products. This paper shares current scientific information from a quality perspective on risk factors and potential root causes for nitrosamine impurities, as well as recommendations for risk mitigation and control strategies.

Lessons from CDER's Quality Management Maturity Pilot Programs.

Between October 2020 and March 2022, FDA's Center for Drug Evaluation and Research (CDER) completed two pilot programs to assess the quality management maturity (QMM) of drug manufacturing establishments. Mature quality systems promote proactive detection of vulnerabilities, prevent problems before they occur, and foster a culture that rewards process and system improvements. A CDER QMM program may help to advance supply chain resiliency and robustness and mitigate drug shortages. One pilot program evaluated seven establishments located within the U.S. that produce finished dosage form products marketed in the U.S. A second pilot program evaluated eight establishments located outside the U.S. that produce active pharmaceutical ingredients used in drug products marketed in the U.S. The execution of these pilot programs afforded FDA the opportunity to learn important lessons about the establishment QMM assessment process, scoring approach, assessor behaviors, and perceptions of the assessment questions, reports, and ratings. Many of the participating establishments reported that the QMM pilot assessments helped to identify their strengths, weaknesses, and new areas for improvement which they had not previously identified through internal audits or CGMP inspections. There has been a great deal of interest in the outcomes of CDER's QMM pilot programs and this paper describes, for the first time, the lessons CDER learned and will continue to heed in the development of a QMM program.

Steps toward nebulization in-use studies to understand the stability of new biological entities.

The need for novel biological drugs against respiratory diseases has been highlighted during the Coronavirus (COVID-19) pandemic. The use of inhalation presents challenges to drug product stability, which is especially true for delivery using nebulizers (jet versus mesh technologies). The late-stage process of drug development in the pharmaceutical industry requires the investigation of in-use stability. In-use studies generate data that are guided by the requirements of regulatory authorities for inclusion in the clinical trial application dossier. In this review, I introduce the initial aspects of in-use stability studies during the development of an aerosol formulation to deliver biologics with a nebulizer. Lessons learned from this experience can guide future development and planning for formulation, analytics, material compatibility, nebulization process, and clinical trial preparations.

Quality by design (QbD) approach in marketing authorization procedures of Non-Biological Complex Drugs: A critical evaluation.

The emergence of innovator-driven complex drug products, such as Non-Biological Complex Drugs (NBCDs), has provided disruptive advances in the Nanotechnology and Biotechnology fields. However, the design and development of NBCDs can be particularly challenging due to some unresolved scientific and regulatory challenges associated with the pharmaceutical quality assessment. The application of a more holistic, systematic, integrated science and risk-based approach, such as Quality by Design (QbD), is essential to address key scientific, technological, and regulatory constraints in the research and development of the NBCDs. The deeper product and process understanding derived from the implementation of the QbD approach ensures consistent, reliable, and high-quality pharmaceutical products. Furthermore, this approach promotes innovation and continuous improvement in the entire product lifecycle. Regulatory authorities highly recommend QbD-based submissions to successfully translate NBCDs from laboratory-scale research to the pharmaceutical market with the required quality, safety, and efficacy standards. The main aim of this article is to obtain a comprehensive and in-depth investigation into the state of implementation of the QbD approach in the pharmaceutical development and marketing authorization of NBCDs in Europe and the United States, through the analysis of the available data from their regulatory dossiers. In addition, it aims to understand and discuss how the QbD approach is used and implemented for complex drug products in the pharmaceutical industry, highlighting the gaps and challenges involved with its implementation. An analysis is held regarding QbD's advantages in terms of knowledge growth, regulatory flexibility, and the speed of development based on big data science, along with the reduction of regulatory failures and market withdrawals.

Considerations for the chemistry, manufacturing and Controls (CMC) - quality package for COVID-19 vaccines- interim lessons learnt by the European medicines Agency (EMA).

The European Medicines Agency (EMA) has approved five pandemic COVID-19 vaccines (prior to April 2022) and many others are in the pipeline. The commentary describes how timely approval and rapid manufacturing capacity scale up could be achieved from our perspective. The commentary considers the need for: early, continuous engagement with the regulator for COVID-19 vaccines; understanding key Chemistry, Manufacturing and Controls (CMC) challenges in order to build a successful COVID-19 vaccine CMC dossier; investing in production and testing site readiness for COVID-19 vaccines; CMC Lifecycle and post-approval planning for COVID-19 vaccines as well as future directions including international regulatory cooperation. EMA's experience of the CMC scientific considerations, which facilitated both timely approvals (as Conditional Marketing Authorisations) and rapid increase in production capacity and supply, is of interest to healthcare professionals, academia, pharmaceutical industry and global regulators to communicate the flexibility and agility applied to COVID-19 vaccines by the EU regulatory system and how these activities can be optimised while complying with the strict quality standards in the EU.

Microbiological Quality of Selected Local and Imported Non-Sterile Pharmaceutical Products in Dar es Salaam, Tanzania.

Background: Pathogenic and non-pathogenic microbial contaminants can cause physical-chemical alterations of pharmaceuticals and medicine-related infections. This study aimed to examine the microbiological quality of selected local and imported non-sterile pharmaceutical products in the Dar es Salaam market and the antibiogram of the isolated microorganisms. Methods: Samples were collected between April and June 2021 and analysed for microbial content as per the harmonised methods of the European Pharmacopoeia (EP). Antibiotic susceptibility of the microbial isolates was studied using Kirby-Bauer disc diffusion method. Results: Fifty percent (50%) of the samples failed both bacterial and fungal enumeration tests. In this study, local products recorded lower microbial counts than imported products. Major bacterial contaminants isolated were P. aeruginosa (45.5%), S. epidermidis, (45.5%) and K. pneumoniae, while major fungal contaminants were A. flavus (58.3%), followed by A. fumigatus (25%) and Penicillium spp (16.7%). The isolated bacterial contaminants recorded high resistance levels to commonly used antibiotics. Conclusion: The tested products were contaminated with microorganisms at different levels, most of them exceeding the maximum acceptable colony counts. Syrups or suspensions were more contaminated than tablets and capsules. The isolated bacterial contaminants were highly resistant to commonly used antibiotics. Recommendations: We recommend that pharmaceutical manufacturers abide by good manufacturing, distribution and storage practices to limit contamination and cross-contamination of products. Responsible drug regulatory authorities should heighten the frequency of inspection of manufacturing facilities and regularly conduct post-marketing surveillance (PMS) of registered products to assess continued conformity to GMP guidelines. Future studies should involve samples collected directly from manufacturing sites.

Meeting report: an exploration into the scientific and regulatory aspects of pharmaceutical drug quality in the United States.

INTRODUCTION: The University of Florida College of Pharmacy, Department of Pharmaceutical Outcomes and Policy hosted a seminar 6-7 March 2021, on the quality of pharmaceutical products in the United States. This meeting report summarizes the topics presented at the seminar and highlights the expert opinions offered by the presenters. AREAS COVERED: The seminar, held virtually due to the COVID-19 pandemic, included slide presentations and faculty-moderated panel discussions from experts in the field. These experts from regulatory, academic, and private sectors discussed bioequivalence standards, existing and emerging efforts to promote quality in brand and generic manufacturing, as well as market-based solutions throughout the drug supply chain. EXPERT OPINION: The time spent understanding bioequivalence standards during the seminar felt especially important and relevant in our current pandemic environment, given the present need to have confidence in the science of drug development and to advocate for the safety of pharmaceuticals. Also an important point to emphasize from the seminar, was that every stakeholder along the drug supply chain has a responsibility to do their part to maintain its quality. And those in attendance, many of whom were students of healthcare sciences, were encouraged to be leaders in their fields and develop strategies to advance innovative improvements.

Pharmaceutical quality evaluation of marketed vildagliptin tablets in Bangladesh based on the United States Pharmacopeia specifications.

Continuous monitoring of pharmaceutical products is vital because it matters to human health. Here we aimed to assess the quality parameters of commercially available vildagliptin tablets in Bangladesh. We tested the tablets for the content uniformity, hardness, friability, disintegration, dissolution, and potency. Then, we fitted the dissolution data with kinetic models to investigate the release pattern of the studied brands. Moreover, we applied a mathematical model-independent approach to compare the dissolution profiles of the brands. The interchangeability was determined using difference and similarity factors. Weight variation, friability, and hardness were between 150.35±1.26 to 230.8±1.98 mg, 0 to 0.88%, and 47.3±5.09 to 108.1±1.92 N, respectively. All tablets disintegrated within 0.54±2.85 to 7.69±2.14 min in distilled water. The potency of tablets in 0.1 N HCl and PBS (pH 6.8) were between 97.67±2.58 to 105±0.95% and 99±4.63 to 105±1.65%, respectively. The drug release (%) in 0.1 N HCl and phosphate-buffered saline (PBS) (pH 6.8) after 60 min were between 99.37±1.80 to 111.09±0.64% and 96.59±3.52 to 109.57±0.53%, respectively. All the brands complied with the United States Pharmacopeia (USP) specification for physicochemical properties. Also, we observed the drug release patterns of vildagliptin tablets matched with different kinetic models. We found only one substitutable brand with the standard product regardless of the dissolution medium. In-vitro chemical equivalence is not always consistent with bioequivalence. Therefore, continuous evaluation of marketed products is essential to ensure the desired quality.

A strategy for population pharmaceutical quality assessment based on quality by design.

From a regulatory perspective, drug quality consistency evaluation must concern different processes used for the same drug. In this study, an assessment strategy based on quality by design (QbD) was developed for population pharmaceutical quality evaluation. A descriptive analysis method based on QbD concept was first established to characterize the process by critical evaluation attributes (CEAs). Then quantitative analysis method based on an improved statistical process control (SPC) method was established to investigate the process indicators (PIs) in the process population, such as mean distribution, batch-to-batch difference and abnormal quality probability. After that rules for risk assessment were established based on the SPC limitations and parameters. Both the SPC parameters of the CEAs and the risk of PIs were visualized according to the interaction test results to obtain a better understanding of the population pharmaceutical quality. Finally, an assessment strategy was built and applied to generic drug consistency assessment, process risk assessment and quality trend tracking. The strategy demonstrated in this study could help reveal quality consistency from the perspective of process control and process risk, and further show the recent development status of domestic pharmaceutical production processes. In addition, a process risk assessment and population quality trend tracking provide data-based information for approval. Not only can this information serve as a further basis for decision-making by the regulatory authority regarding early warnings, but it can also reduce some avoidable adverse reactions. With continuous addition of data, dynamic population pharmaceutical quality is meaningful for emergencies and decision-making regarding drug regulation.

ICH Q10 Pharmaceutical Quality System Guidance: Understanding Its Impact on Pharmaceutical Quality.

The International Council for Harmonization (ICH) "Q10 Pharmaceutical Quality Systems" (ICH Q10) guidance was introduced to address the growing gap between current good manufacturing practices and pharmaceutical manufacturing quality systems. This study evaluated the impact of the ICH Q10 guidance on the PQS of pharmaceutical manufacturers. Data were obtained from the enabler questionnaire from pharmaceutical manufacturers surveyed by the St. Gallen OPEX Benchmarking Program. These results represent the degree of implementation for enabler-focused questions based on a 5-point Likert scale self-assessment. Data analysis included a comparison of means and medians before and after the release of the ICH Q10 guidance and annual changes. There was a statistically significant difference for enabler implementation as a whole (p value < 0.0000), before and after the release of ICH Q10. Furthermore, statistically significant differences were observed for four of the five enabler categories (p values <0.05). In particular, the EMS enabler category showed a decrease in mean enabler score, suggesting the Management Responsibilities ICH Q10 PQS element was not effectively described or implemented. These results indicate that the release of ICH Q10 had a positive impact on the PQSs of pharmaceutical manufacturers. This was driven primarily by the changes observed in the TQM and JIT enabler categories and complimented by the TPM and BE categories. This would suggest that the Management Review, Change Management System, and Process Performance and Product Quality Monitoring System ICH Q10 PQS elements were all effectively described and implemented.
