Out of the boxes, out of the silos: The need of interdisciplinary collaboration to reduce poor-quality medical products in the supply chain.

In this paper, we argue that understanding and addressing the problem of poor-quality medical products requires a more interdisciplinary approach than has been evident to date. While prospective studies based on rigorous standardized methodologies are the gold standard for measuring the prevalence of poor-quality medical products and understanding their distribution nationally and internationally, they should be complemented by social science research to unpack the complex set of social, economic, and governance factors that underlie these patterns. In the following sections, we discuss specific examples of prospective quality surveys and of social science studies, highlighting the value of cross-sector partnerships in driving high-quality, policy-relevant research in this area.

Collaborative study for the establishment of Ph. Eur. Human albumin (molecular size) Biological Reference Preparation batches 1, 2 and 3.

To comply with European Pharmacopoeia (Ph. Eur.) monograph Human albumin solution (0255), albumin solutions have to be tested for molecular-size distribution by size-exclusion chromatography (SEC). However, differences in interpretation of the test results continue to be observed among albumin manufacturers in Europe. A collaborative study was run by the European Directorate for the Quality of Medicines & HealthCare (EDQM), under the aegis of the Biological Standardisation Programme (BSP), to support the revision of Ph. Eur. monograph 0255 and to establish a Biological Reference Preparation (BRP) for use in the molecular-size distribution test. In 2019, Ph. Eur. Expert Group 6B proposed to include an analytical improvement of the SEC procedure in the monograph, which was then submitted for public enquiry. This publication describes the evaluation of three candidate BRPs to serve as a tool for both the system suitability test (SST) and albumin monomer and dimer peak identification according to the proposed revised methodology. Three Official Medicines Control Laboratories (OMCLs) involved in the official batch release of human albumin solution took part in the study. Based on the study results, the candidate BRPs were found suitable for purpose and were adopted by the Ph. Eur. Commission as Ph. Eur. Human albumin (molecular size) BRP batches 1, 2 and 3 concomitantly with the revised monograph Human albumin solution (0255) in November 2020.

Assessments of the quality systems of pharmaceutical distributors: a remote approach to be applied in times of COVID-19 and beyond.

BACKGROUND: Adequate quality systems throughout pharmaceutical supply chains are crucial to protect individuals and communities from substandard and falsified medical products. Thus, pharmaceutical distributors are regularly assessed by qualified experts. Since the COVID-19 pandemic has forced a suspension of normal activities, remote assessments via videoconferencing may represent a temporary alternative to on-site audits. We exploratorily evaluated the feasibility of remote assessments of pharmaceutical distributors, located in a low- or middle-income country hard-to reach during the COVID-19 pandemic. METHODS: We conducted pilot remote assessments of four conveniently selected distributors. The expert was remotely connected via videoconference, and supported by an in-country assessment facilitator (ICAF), who had received ad hoc training and was present at the assessed facility. First, the remote expert assessed the quality assurance (QA) activities and rated their compliance with the standards of the World Health Organization Good Storage & Distribution Practices (GSDP), as per routine practice. Second, s/he assessed the completeness, clarity and accuracy of data collected remotely, first per distributor, and then in aggregated form. RESULTS: Data completeness was assessed by the expert as excellent, while clarity and accuracy were good. Overall data quality (a combination of completeness, clarity and accuracy) was good, with no major differences across QA activities, nor across distributors. Contextual limitations included poor internet connection, language barriers, and distributors' lack of familiarity with QA terminology. CONCLUSIONS: Our findings are exploratory and cannot be extrapolated to other contexts, nor to other types of audits. Nonetheless, this pilot experience suggests that a well-planned remote assessment of pharmaceutical distributors, conducted with the support of a well-trained onsite ICAF, can provide data of acceptable quality, allowing to assess GSDP-compliance and to make temporary decisions about licensing or purchasing. Purchasers and policy makers should read the results of remote assessments in light of their intrinsic limitations. At the moment, onsite assessments remain the gold standards, but this could change in the longer term, with improved information technology and in light of the need to avoid unnecessary travels. Furthermore, remote assessments could be considered for routine pre-screening candidates for on-site assessments, and for targeted follow-up of on-site assessment.

QUALITY ASSURANCE OF MEDICINES: THE STATE AND TRENDS OF THE EUROPEAN UNION AND UKRAINE LEGISLATION DEVELOPMENT.

OBJECTIVE: The aim: Scientific substantiation of the state and tendencies of development at the present stage of the legislation of the European Union and Ukrainian legislation on quality assurance of medicines. PATIENTS AND METHODS: Materials and methods: Using the biblio-semantic, systematic-review, analytical, formal-legal and comparative-law methods, the individual regulatory sources of pharmaceutical legislation of the EU and Ukraine were studied. CONCLUSION: Conclusions: The paper identifies that pharmaceutical legislation of the EU and Ukraine on quality assurance of medicines at the present stage of their development have common features, which include the number, disorder of existing legal acts, which creates conflicts between them and the potential for gaps in regulation. The main trend in the development of this legislation in the EU and Ukraine is the disparity of legal acts and the lack of significant legislative efforts to codify them.

Transfusion medicine: Overtime paradigm changes and emerging paradoxes.

This essay aims to discuss some aspects of blood transfusion in the perspective of the changes that occurred over time as well as modifications of the paradigms that transformed the activities and the organization of blood transfusion services. Without specific knowledge, pioneers envisioned precision and personalized medicine, rendering transfusion medicine operational. Transfusion medicine is like The Picture of Dorian Grey: always young despite being old and sometimes appearing old-fashioned. Over the years, the transfusion medicine discipline has evolved, and major progress has been achieved, despite some troublesome periods (for example, the tainted blood scandal, and-at the time being-the offending plasma market and the selling of human parts). Transfusion medicine has at all times implemented the rapidly developing biomedical technologies to secure blood components. The safety of blood components has now reached an exceptional level in economically wealthy countries, especially compared to other health care disciplines. Strengthening of the safety has mandated that blood donors and recipients are unrelated, an issue which has eased preservation and fractionation practices; blood is no longer arm-to-arm transfused and neither is whole blood, the commonest component. However, it is interesting to note that a revival is occurring as whole blood is back on stage for certain specific indications, which is one among the many paradoxes encountered while studying this discipline.

PATIENTS AND METHODS: Materials and methods:Scientific works that are devoted to the outspread of digital technologies in healthcare, the provisions of the European Convention on Human Rights, the ECHR's practice on the protection of human rights to privacy, the provisions of the EU secondary legislation that regulate the supply of medicines are studied. The methodology of this article is based on comparative and legal analysis techniques and includes system-structural method, method of generalization, method of analysis and synthesis as well. CONCLUSION: Conclusions:The blockchain technology in medicine and pharmacology will increase the level of protection of human rights to healthcare quality.

Institutional barriers and enablers to implementing and complying with internationally accepted quality standards in the local pharmaceutical industry of Pakistan: a qualitative study.

Complying with good manufacturing practices (GMP) and ensuring a quality system is integral to production and supply of quality medicines and achieving universal health coverage. This study focus on the local production of medicines in Pakistan, a lower middle-income country that has observed considerable growth in the number of pharmaceutical companies over the past two decades. Against this background, we investigated: (1) How is quality assurance (QA) and GMP compliance understood and acted upon by local pharmaceutical manufacturers?; (2) What are the institutional barriers and enablers for QA and GMP compliance in the local pharmaceutical sector from the perspective of key stakeholders?; and (3) What are the institutional barriers and enablers for strengthening local regulatory capacity to improve QA in the industry in the long term? We used a qualitative study design involving 22 interviews of the drug regulatory bodies (n = 9), academia (n = 3) and local manufacturers (n = 10), identifying key themes in data by thematic analysis. Document analysis was used to collect additional information and supplement the interview data. We identified that manufacturing facilities operated under different GMP standards and interpretations, pointing towards an absence of harmonization in quality standards across the industry. Views diverged about the status of GMP compliance, with interviewees from academia presenting a more critical view compared with regulators who promoted a more positive story. Among the barriers explaining why companies struggled with quality standards, the lack of a mindset promoting quality and safety among profit-oriented manufacturers was prominent. At the federal level, DRAP's establishment represented an institutional improvement aiming to promote QA through inspections and guidance. While some positive measures to promote quality have been observed, the need for DRAP to strengthen its technical and regulatory capacity, enhance its engagement in international collaboration and learning, and improve transparency and accountability were highlighted. Overall, since the challenges in Pakistan are shared with other low- and middle-income countries with local production, there is a need to commit to international collaborative mechanisms, such as those lead by WHO, on this issue.

Issues on medicine toward realizing Universal Health Coverage / 国際保健医療

  Health service provision is one of the components in Universal Health Coverage (UHC). Medicines are vital for health services, and they should be affordable and accessible for safe and appropriate usage for everyone.  This article is a report on the symposium “Medicines for UHC,” held in the academic meeting of the Japanese Association of International Health in December 2017.  In Lao PDR, a study was conducted in urban and rural hospitals examining lists of available medicines, as well as their usage, distribution, and prices. The study showed that neurological medicines including anesthetics made up 29% of all medicines used in the urban central hospital, as it was one of the few hospitals that provided complex surgeries in Laos, resulting in a high concentration of patients. Anti-tuberculosis, ARV, and anti-Malaria medicines, as well as vaccines, were provided by Global Fund, GAVI, and other organizations, so that their costs were not included in the hospital’s procurement lists. While anti-microbial medicines only accounted for 13% of the medicines used at the urban central hospital, they accounted for 43% of those in rural hospitals, where most patients presented with upper respiratory and digestive infections. While the Ministry of Health sets the standards for evaluating and regulating the quality and cost of medicine, individuals can purchase medicines from private pharmacies without prescriptions, making it difficult to evaluate appropriate usage.  Regarding the quality of medicines, distribution companies, health workers, and patients cannot distinguish between authentic and falsified or substandard medicines. As an example, after a study in Cambodia revealed the existence of inappropriate medicines, the Cambodian government required companies to provide results of dissolution tests.  As the limitations on pharmaceutical regulatory authorities and their staff in developing countries impact their capabilities, we recommend supporting them in establishing effective pharmaceutical regulations internationally.

Quality of medicines in resource-limited settings: need for ethical guidance.

The quality of medicines is generally adequately assured by manufacturers and regulatory authorities for well-resourced settings, while the implementation of existing quality standards is challenged in many low- and middle-income countries. This situation of multiple pharmaceutical standards raises the question whether it could ever be ethically justified to compromise on the quality assurance of medicines depending on what individuals, communities, or societies can afford. In this paper, we contend that ethically, any unjustified exceptions to medicines' quality assurance represents a violation of the principles of beneficence and non-maleficence. Exceptions are only acceptable in exceptional and temporary circumstances, if based on a meaningful quality risk assessment, guided by a rigorous ethical framework built on the principles of independence, technical competence, transparency, and accountability. We also discuss how such exceptional and temporary circumstances should be defined/justified. Finally, we propose that empirical bioethics should acknowledge the existence of these dilemmas in public health, and help to build a normative approach to dealing with them. Ideally, an international group of experts in quality assurance/regulatory affairs and health ethicists should be set up to take up this topic and formulate a Guide to Ethical Principles of Quality Assurance of Medical Products.

The Belgian commitment to pharmaceutical quality: a model policy to improve quality assurance of medicines available through humanitarian and development programs.

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.

Fighting poor-quality medicines in low- and middle-income countries: the importance of advocacy and pedagogy.

The globalization of pharmaceutical production has not been accompanied by a strengthening and harmonization of the regulatory systems worldwide. Thus, the global market is characterized today by a situation of multiple standards, and patients in low- and middle-income countries are exposed to the risk of receiving poor-quality medicines. Among those who first raised the alarm on this problem, there were pioneering humanitarian groups, who were in a privileged position to witness the gap in quality of medicines between high-income countries and low- and middle-income countries. Despite an increasing awareness of the problem and the launch of some positive initiatives, the divide in pharmaceutical quality between the North and the South remains important, and insufficiently addressed. More advocacy is needed for universal access to quality-assured medicines. It should target all those who are strongly "involved" with medicines: regulators, international organizations, journalists, purchasers, prescribers, program managers, policy makers, public health actors and the patients. Advocacy should be based on evidence from research and monitoring programs, and technical concepts should be translated in lay language through communication tools that address all the stakeholders. The fight to ensure universal access to quality medicines needs the participation of all, and can only be successful if grounded in common understanding.

Standardization of allergen products: 2. Detailed characterization of GMP-produced recombinant Phl p 5.0109 as European Pharmacopoeia reference standard.

BACKGROUND: The Biological Standardization Programme of the European Directorate for Quality of Medicines and Healthcare (EDQM) aims at the establishment of well-characterized reference standards based on recombinant allergens and validated assays for the quantification of major allergen content. The objective of this study was to examine the detailed physicochemical and immunological characterization of recombinant Phl p 5.0109, the second available allergen reference standard. METHODS: Recombinant Phl p 5.0109 PP5ar06007 was produced under GMP conditions and analyzed by an array of physicochemical and immunological methods for identity, quantity, homogeneity, and folding stability in bulk solution, as well as thermal denaturation, aggregation state, and biological activity when formulated for long-time storage. RESULTS: PP5ar06007 revealed as a highly homogeneous, monomeric, well-folded preparation of rPhl p 5.0109, as documented by mass spectrometry, SDS-PAGE, isoelectric focusing, size-exclusion chromatography with light scattering, circular dichroism, and infrared spectroscopy. Upon storage at +4°C, PP5ar06007 retained the monomeric state for at least 2 months. A protein quantity of 1.56 ± 0.03 mg/ml was determined by amino acid analysis in PP5ar06007, and its biological activity was shown to be comparable to natural Phl p 5 in terms of basophil activation and T-cell reactivity. CONCLUSIONS: Recombinant Phl p 5.0109 PP5ar06007 was characterized extensively at the physicochemical and immunological level. It revealed to be a highly stable, monomeric, and immunologically equivalent of its natural counterpart. PP5ar06007 is now available as European Pharmacopoeia allergen reference standard for grass pollen products.

Aseptic preparation of parenteral medicinal products in healthcare establishments in Europe.

In many cases, parenteral medicines with a marketing authorisation cannot be administered directly to patients, that is, they are not presented in ready-to-administer form. Before administration to patients, these medicines have to be reconstituted. Reconstitution has a special position; it can neither be seen as industrial manufacture nor as 'regular' pharmacy preparation. There are other processes in healthcare establishments (eg, parenteral nutrition), related to the reconstitution process, where the requirements of national quality assurance standards for the safe preparation of sterile products are equally important and have to be fulfilled. In European healthcare establishments, aseptic preparation of parenteral medicinal products is considered to be a process of crucial importance for patient safety because errors in the preparation of these medicines may lead to a product that can cause immediate damage to patients. Aseptic preparation of medicinal products is carried out in hospital pharmacies as well as in clinical areas in healthcare establishments. The Committee of Experts on Quality and Safety Standards for Pharmaceutical Practices and Pharmaceutical Care (Council of Europe; hereafter: Committee of Experts), supported by the European Directorate for the Quality of Medicines & Healthcare, is undertaking work on the topic of aseptic preparation of medicines. The work is carried out in cooperation with the European Association of Hospital Pharmacists on the basis of a Resolution CM/Res AP(2011)1 on Quality and Safety Assurance requirements for Medicinal Products prepared in Pharmacies for the Special Needs of Patients, which was adopted by the Committee of Ministers on 19 January 2011. The Resolution includes some recommendations and an outlook to further work on reconstitution of parenteral medicines. A survey that was sent to the different European countries demonstrated that there is no or just limited regulation concerning reconstitution in Europe. This article describes the risks associated with poor reconstitution practices and the previous work as well as the ongoing activities concerning reconstitution at the European level. The article emphasises the need for regulation in this area, which is missing at present. It is expected that consensus can be reached on a guidance document for reconstitution at the European level.

A multi-dose serological assay suitable to quantify the potency of inactivated rabies vaccines for veterinary use.

The mouse vaccination-challenge test, which is the most widely used method for determining the potency of inactivated rabies vaccines, is imprecise, time-consuming, and causes severe distress to the test animals. An alternative single-dose serological method has been implemented in the European Pharmacopoeia Monograph 0451 to replace the mouse challenge test for batch release. This single-dose limit method provides semi-quantitative results, but is not suitable for quantifying potency. We have now extended this serological method to a multi-dose format which allows a quantification of vaccine potency. In studies including all rabies vaccine strains relevant for Europe, we found dose-dependency for all vaccines and standard preparations. We have demonstrated that the multi-dose serological approach provides reliable quantitative potency results and is more precise than the mouse vaccination-challenge test. We have shown that adjuvanted vaccines can be calibrated against non-adjuvanted material, and that reference material can be calibrated against the International Standard. The method is therefore capable of assigning potency with the additional advantage of requiring fewer animals and reducing distress. Once the applicability of the method has been further verified in a collaborative study, it can complement the single-dose assay and eventually eliminate the need for the mouse challenge test.

Genetic strain modification of a live rabies virus vaccine widely used in Europe for wildlife oral vaccination.

In Europe, the main reservoir and vector of rabies has been the red fox (Vulpes vulpes). Oral immunization of foxes with live vaccines, using attenuated rabies strains (SAD B19, SAD Bern), apathogenic mutants of an attenuated strain (SAG2) and the vaccinia-rabies glycoprotein recombinant virus vaccine (V-RG), has been shown to be the most effective method for the control and elimination of rabies. Among all vaccines currently used for wildlife oral vaccination, one vaccine (marketed as SAD Bern strain) has been widely used in Europe since 1992 with the distribution of 17million of baits in 2011. Because of the potential environmental safety risk of a live virus which could revert to virulence, the full genome sequencing of this vaccine was undertaken and the sequence was characterized and compared with those of referenced rabies viruses. The vaccine showed higher similarity to the strains belonging to the SAD B19 vaccine virus strains than to the SAD Bern vaccines. This study is the first one reporting on virus strain identity changes in this attenuated vaccine.

Qualidade de cápsulas de fluoxetina disponibilizadas pelo Sistema Único de Saúde: estudo in vitro das condições do ensaio de dissolução / Quality of fluoxetine capsules available from the Sistema Único de Saúde: in vitro study of conditions used in dissolution test

A fluoxetina é um antidepressivo amplamente prescrito, assim torna-se importante verificar a qualidade das cápsulas, principalmente, por ser um medicamento disponibilizado à saúde pública através do Sistema Único de Saúde. A qualidade das cápsulas de fluoxetina fornecidas pelo SUS foi avaliada conforme a Farmacopeia Brasileira, quanto à determinação do tempo de desintegração, peso, teor e uniformidade de conteúdo. Devido a ausência de harmonização entre os compêndios oficiais de análise mais utilizados no Brasil, quanto às condições do ensaio de dissolução, avaliou-se a influência do meio de dissolução (HCl 0,1 mol L-1 e água destilada) e do sistema de agitação (pá e cesta) no desempenho das cápsulas através do perfil de dissolução. Para o doseamento aplicou-se o método espectrofotométrico co-validado em nosso laboratório. As cápsulas apresentaram peso ± 2,2 % (limite de variação ± 10%) e 1,49 % CV, desintegração 5’45” (máx. 45’), uniformidade de conteúdo 3,47 (< L1 = 15) e teor 102,13 % (90 % - 110 %). As variações nas condições do teste de dissolução não influenciaram o comportamento da fluoxetina nas cápsulas nesse teste (p > 0,05). Os demais ensaios indicam qualidade adequada do medicamento disponibilizado pelo SUS.

Fluoxetine is a widely prescribed antidepressant, so it is important to check the quality of the capsules, especially since it is a medicine made available to the public throughout Brazil by the free Sistema Único de Saúde (SUS). The quality of fluoxetine capsules provided by the SUS was assessed in conformity with the Brazilian Pharmacopoeia, by determining the disintegration time, weight, assay and uniformity of dosage units. Given the lack of harmonization, among the official compendia of analytical methods commonly used in Brazil, on the conditions to be used in the dissolution test, we tested the influence of the dissolution medium (0.1 mol L-1 HCl or distilled water) and stirring system (paddle or basket) on the dissolution performance of the capsules. To assay the drug we used the spectrophotometric method co-validated in our laboratory. The capsule weight varied ± 2.2% (limits of variation ± 10%), with RSD 1.49%, and disintegration 5’45” (max. 45’); uniformity of dosage units acceptance value was 3.47 ( 0.05). This and the other tests indicated that the quality of the generic product provided by the SUS is adequate.
