Evaluation of a Novel LC-MS/MS Based Analytical Method for the Risk Assessment of Nitrosamines in Pharmaceutical Products and Packaging Materials

The detection of nitrosamine impurities, particularly small dialkyl types, which are frequently known to be potent mutagenic carcinogens, in some Sartan group active pharmaceutical ingredients (APIs) and finished drug products caused global regulatory organizations to have concerns. Accordingly, Registration Holders/Applicants, API manufacturers, and their raw material suppliers are required to check the presence of nitrosamines in their products and carry out risk assessments using the quality risk management principles specified in the ICH Q9 guide. In this context, a new LC-MS/MS method has been developed and validated for the simultaneous determination of NDMA, NDEA, NMBA, NDIPA, NEIPA, NDBA, and MeNP nitrosamine compounds in API and finished products as well as in primary packaging materials, one of the risk sources. This validated method was applied to check the nitrosamine content may occur from canister, blister, printed aluminum foil, nasal spray, and eye drop packaging materials as part of the Extractables & Leachables studies arising from interactions between the product and the primary packaging. For the determination and quality control of nitrosamines in sartan group pharmaceutical products and packaging materials, the developed LC-MS/MS analytical method offers highly reliable, fast, high accuracy, good sensitivity and simultaneous detection even at low concentrations.

Multivariate Analysis and Computational Predictability of Modified Release Formulation of Chirally Pure Metoprolol Succinate

This study employs computational techniques to predict the performance of a modified-release matrix formulation of chirally pure S (-) Metoprolol Succinate, using a Quality by Design (QbD) approach. The research defines the Quality Target Product Profile (QTPP) and Critical Quality Attributes (CQAs) of the S (-) Metoprolol Succinate matrix formulation. To assess risks, an Ishikawa diagram and Failure Mode Effect Analysis (FMEA) following ICH Q8 guidelines were conducted. The formulation screening process utilized Plackett–Burman design, followed by optimization through Box–Behnken design. The modified-release formulation was developed using high shear granulation, incorporating a combination of high and low viscosity Hydroxypropyl Methylcellulose (HPMC) polymers along with other excipients. The impact of polymer composition and stearic acid on the release profile of S (-) Metoprolol Succinate was investigated, revealing their significant influence on the drug delivery system's desired effect. Specifically, the variables X1: HPMC K4M and X2: HPMC K100M were identified as key factors affecting drug release (Y1). Statistical analysis (ANOVA) confirmed the significance of the selected model, with predicted outcomes aligning well with observed results, comparable to the reference product Seleken® XL range. Both drug content and release performance were found to be similar to the innovator formulation. In summary, this investigation underscores the potential of employing a QbD approach with a combination of low and high viscosity HPMC polymers to achieve precise single-dose delivery of S (-) Metoprolol Succinate.

Identifying design spaces as linear combinations of parameter ranges for biopharmaceutical control strategies

According to ICH Q8 guidelines, a biopharmaceutical manufacturer may submit a design space (DS) definition as part of the regulatory approval application, in which case process parameter (PP) deviations within this space are not considered changes and do not trigger a regulatory post approval procedure. A DS can be described by non-linear PP ranges, i.e., the range of one PP conditioned on specific values of another. However, independent PP ranges (linear combinations) are often preferred in biopharmaceutical manufacturing due to their operational simplicity, as mentioned in the guideline. While statistical software such as Modde supports the calculation of a DS comprised of linear combinations, their algorithms are generally based on discretizing the parameter space - an approach that suffers from the curse of dimensionality as the number of PPs increases. Here, we introduce a novel method for finding linear PP combinations using a numeric optimizer to calculate the largest design space within the parameter space that results in critical quality attribute boundaries within acceptance criteria, predicted by a regression model. A precomputed approximation of tolerance intervals is used in inequality constraints to facilitate fast evaluations of this boundary using a single matrix multiplication. The correctness of the method was validated by comparing results to that of a grid-based approach and, in a simple case, to an analytically defined ground truth. In the examples investigated, the volume of the resulting DS was significantly larger than that of the grid method, with the improvement being proportional to the granularity of the grid and the number of parameters involved. Furthermore, computational time for the optimization-based approach is several orders of magnitude faster in higher dimensions. In addition, a proposed weighting scheme can be used to favor certain PPs over others and therefore enabling a more dynamic approach to DS definition and exploration. The increased PP ranges of the larger DS provide greater operational flexibility for biopharmaceutical manufacturers.

Soft Gelatine Capsules- Critical Quality Attributes of Chosen Excipients and Capsules Parameters Following the Quality by Design Concept

Soft gel capsules are a common form of medicine and food supplements. Quality, productivity and manufacturing time is crucial for producers during their development and industrial operations. To ensure the best quality of the product, it is necessary to know all critical process steps and parameters. The use of QbD elements is to ensure the quality of the drug product throughout its "life cycle". Quality by design (QbD) and its elements are described by the International Council of Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) and in their guideline - chapter ICH Q8 (Pharmaceutical Development). One of the first steps in pharmaceutical product development is to prepare Quality Target Product Profile (QTPP) and analyse Critical Material Attributes (CMAs) and Critical Quality Attributes (CQAs) of excipients, active pharmaceutical ingredient (API) and final product. During this research, we investigated the CQAs of the excipients used in vitamin D3 soft gelatin capsules containing high doses of cholecalciferol, from 10 000 to 200 000 IU per capsule. We considered the viscosity of the gelatin mass, the effect of the addition of dye on the viscosity, and the impact of the colour of the gelatin mass on the active substance content in the final capsules. It was also investigated oily carriers (medium chain triglycerides and safflower oil) and antioxidants (alpha-tocopherol acetate vs butylhydroxytoluene), and their effect on API concentration in the capsule.

The Role of the Geometric Configuration of Diethylaminoethanol Derivative in the Pharmaceutical Development of a Dosage Form Based on It

Introduction. A comprehensive study of the active pharmaceutical ingredient (API) molecule is one of the defining criteria for pharmaceutical development according to the Quality by Design (QbD) concept and the ICH Q8 framework. The spatial arrangement of atoms in the molecule often has a significant impact on the physicochemical and technological properties of API, and hence on the method of producing dosage form based on it.Aim. To study some properties of substances, geometrical isomers of the molecule, which is a derivative of diethylaminoethanol (DEAE), as well as to compare the selected technologies for the preparation of dosage form.Materials and methods. The objects of the study were two substances, spatial isomers of the molecule, a derivative of DEAE, possessing neuroprotective, antiastenic and antioxidant effects. The study of properties of API and the obtained tablets was carried out in accordance with the requirements of the State Pharmacopoeia of the Russian Federation XIV edition, the Pharmacopoeia of the Eurasian Economic Union, as well as the European Pharmacopoeia 9.0 edition. In this research were used substances that have not expired at the time of the study, as well as authorized for medical use.Results and discussion. The geometrical configuration of the DEAE derivative influences the properties of the API, which has an impact on the stages of pharmaceutical development, especially on the development of the technology and formulation of dosage form. The use of cis-DEAE significantly simplifies the technological process and improves the quality of the resulting drug, and as a consequence, better stability and longer shelf life of dosage form may be achieved.Conclusion. In the course of the study, some properties of cis-DEAE API were studied and compared with similar properties of trans-DEAE. A comparison of tablet preparation technologies based on the two mentioned configurations of the DEAE derivative molecule has been carried out. It was found that the isomers have different technological properties and also differ significantly in moisture adsorption capacity. This property determines the approach to tablet preparation. The technology of tablets based on cis-DEAE appears to be simpler, and dosage form based on it is more stable.

Biopharmaceutics Risk Assessment-Connecting Critical Bioavailability Attributes with In Vitro, In Vivo Properties and Physiologically Based Biopharmaceutics Modeling to Enable Generic Regulatory Submissions.

Quality risk assessment following ICH Q9 principles is an important activity to ensure optimal clinical efficacy and safety of a drug product. Typically, risk assessment is focused on product performance wherein critical material attributes, formulation variables, and process parameters are evaluated from a manufacturing perspective. Extending ICH Q9 principles to biopharmaceutics risk assessment to identify factors that can impact in vivo performance is an upcoming area. This is evident by recent regulatory trends wherein a new term critical bioavailability attributes (CBA) has been coined to identify such factors. Although significant work has been performed for biopharmaceutics risk assessment for new molecules, there is a need for harmonized biopharmaceutics risk assessment workflow for generic submissions. In this manuscript, we attempted to provide a framework for performing biopharmaceutics risk assessment for generic regulatory submissions. A detailed workflow for performing biopharmaceutics risk assessment includes identification of initial CBA (iCBA), their confirmatory evaluation followed by definition of the control strategy. Tools for biopharmaceutics risk assessment, i.e., bio-discriminatory dissolution method and physiologically based biopharmaceutics modeling (PBBM) were discussed from a practical perspective. Furthermore, a case study for CBA evaluation using PBBM modeling for an extended-release product for regulatory submission has been described using the proposed workflow. Finally, future directions of integrating CBA evaluation, biopharmaceutics risk assessment to the FDA Knowledge Aided Structured Assessment (KASA) initiative, the necessity of risk assessment templates, and knowledge sharing between industry and academia are discussed. Overall, the work described in this manuscript can facilitate and provide guidance for biopharmaceutics risk assessment for generic submissions.

Quality culture and knowledge management in the Japanese pharmaceutical industry - A cross-sectional study and case report.

Illicit pharmaceutical manufacturing, affecting the quality of drug products, has been frequently reported 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.

Risk Assessment for a Twin-Screw Granulation Process Using a Supervised Physics-Constrained Auto-encoder and Support Vector Machine Framework.

Quality risk management is an important task when it pertains to the pharmaceutical industry, as this is directly related to product performance. With the ICH Q9 guidelines, several regulatory bodies have encouraged the pharmaceutical industry to implement risk management plans using scientific and systemic approaches such as quality-by-design to asses product quality. However, the implementation of such methods has been challenging as assessment of risks requires accurate quantitative models to predict changes in quality when variations occur. This study describes a framework that quantitatively assesses risk for a twin screw wet granulation process. This framework consists of a physics-constrained autoencoder system, whose outputs are constrained using physics-based boundary conditions. The latent variables obtained from the auto-encoder are used in a support vector machine-based classifier to understand the granule growth behavior occurring within the system. This framework is able to predict the process outcomes with 86% accuracy and classify the granule growth regimes with a true positive rate of 0.73. Based on the classification the risk associated with the process can be estimated.
