Quality-by-Design Is a Tool for Quality Assurance in the Assessment of Enantioseparation of a Model Active Pharmaceutical Ingredient.

ABSTRACT: The design of experiments (DoE) is one of the quality-by-design tools valued in analytical method development, not only for cost reduction and time effectiveness, but also for enabling analytical method control and understanding via a systematic workflow, leading to analytical methods with built-in quality. This work aimed at using DoE to enhance method understanding for a developed UHPLC enantioseparation of terbutaline (TER), a model chiral drug, and to define quality assurance parameters associated with using chiral mobile phase additives (CMPA). Within a response surface methodology workflow, the effect of different factors on both chiral resolution and retention was screened and optimized using Plackett-Burman and central composite designs, respectively, followed by multivariate mathematical modeling. This study was able to delimit method robustness and elucidate enantiorecognition mechanisms involved in interactions of TER with the chiral modifiers. Among many CMPAs, successful TER enantioresolution was achieved using hydroxypropyl ?-cyclodextrin (HP-?-CD) added to the mobile phase as 5.4 mM HP-?-CD in 52.25 mM ammonium acetate. Yet, limited method robustness was observed upon switching between the different tested CMPA, concluding that quality can only be assured with specific minimal pre-run conditioning time with the CMPA, namely 16-column volume (60 min at 0.1 mL/min). For enantiorecognition understanding, computational molecular modeling revealed hydrogen bonding as the main binding interaction, in addition to dipole-dipole inside the CD cavity for the R enantiomer, while the S enantiomer was less interactive.

Project description:An environmental risk assessment is presented for mycophenolic acid (MPA), an immunosuppressive pharmaceutical used for prevention of organ rejection, and its prodrug mycophenolate mofetil (MPM). Mycophenolic acid will not significantly adsorb to activated sludge. In activated sludge, 14 C-MPA attained >80% degradation, supporting an older environmental fate test with the same compound. Based on n-octanol/water distribution coefficient (log DOW ) values of 2.28, 0.48, and ≤-1.54 at pH 5, 7, and 9, respectively, MPA is not expected to bioaccumulate. Sales amounts of MPA+MPM in Europe were used to derive predicted environmental concentrations (PECs) in surface waters; PECs were refined by including expected biodegradation in sewage treatment, average drinking water use, and average dilution of the effluents in the receiving waters per country. In addition, the exposure to pharmaceuticals in the environment (ePiE) model was run for 4 European catchments. The PECs were complemented with 110 measured environmental concentrations (MECs), ranging from below the limit of quantitation (<0.001 µg/L) to 0.656 µg/L. Predicted no-effect concentrations (PNECs) were derived from chronic tests with cyanobacteria, green algae, daphnids, and fish. The comparison of PECs and MECs with the PNECs resulted in a differentiated environmental risk assessment in which the risk ratio of PEC/PNEC or MEC/PNEC was <1 in most cases (mostly >90%), meaning no significant risk, but a potential risk to aquatic organisms in generally <10% of instances. Because this assessment reveals a partial risk, the following questions must be asked: How much risk is acceptable? and Through which measures can this risk be reduced? These questions are all the more important in view of limited alternatives for MPM and MPA and the serious consequences of not using them. Environ Toxicol Chem 2019;38:2259-2278. © 2019 The Authors.

Project description: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.

Project description:Today, a combination of globalization of pharmaceutical production, lack of regulatory harmonization, and weakness of Medicines Regulatory Authorities, creates the "perfect conditions" for poor-quality medicine to circulate in the global market and to penetrate the less-regulated countries. Medicines regulation is the responsibility of the national regulatory authorities in the recipient country, but in the poorer countries, in practice, the responsibility of supply of quality-assured medicines is often taken by Non-Governmental Organizations and other implementers. But with some notable exceptions, many donors lack a pharmaceutical procurement policy with adequate quality requirements; and many implementers lack the skills and expertise needed to orient themselves in the complex web of global pharmaceutical supply. Thus, patients served by humanitarian or development programs may remain exposed to the risk of poor-quality medicines. When public money is used to purchase medicines for medical programs to be carried out overseas, adequate policies should be in place to assure that the same quality requirements are set that would be required for medicines marketed in the "donor" country. We will describe here a policy recently adopted in Belgium, i.e. the "Commitment to Quality Assurance for Pharmaceutical Products", signed in October 2017 by the Vice Prime Minister and Minister for Development Cooperation and 19 Belgian implementing agencies. By signing the new policy, the counterparts committed to ensure quality of medicines in the programs funded by Belgium's Official Development Assistance, and to build quality-assurance capacity in the recipient countries. Implementers are requested to integrate in their financing applications a section for pharmaceutical quality assurance, with a justified budget. They are also invited to consider how costs could be rationalized and mutualized by aligning the strengths of the various implementers. This model policy has the potential to be considered for adoption by other donors, to help to reduce the current multiple standards in pharmaceutical quality, and to contribute to protect vulnerable communities from the plague of poor-quality medicines.Electronic additional filesThe online version of this article (10.1186/s40545-018-0136-z) contains an additional file, which is available to authorized users.
