RESUMEN
Recent advances in synthetic drug manufacturing have introduced a new dynamic to the European regulatory system, with chemically synthesized polypeptide products using biological originator products as their reference medicine. Whereas biosimilars are subject to a dedicated regulatory framework in the EU, synthetically produced follow-on products are not eligible for assessment through this pathway, requiring approval via the traditional generic pathway under Article 10 (1), or via the hybrid pathway under Article 10 (3). This review presents an overview of recent developments in the field of synthetic peptides referencing biological originators in the EU. The use of different regulatory procedures can have potential implications for regulatory assessments, clinical practice and pharmacovigilance. As more complex synthetic products referencing recombinant originator products are expected in the coming years, this study promotes more transparency as well as global alignment about regulatory procedures for chemically synthesised products referencing biological originator products to ensure approval of safe and high-quality generics.
RESUMEN
BACKGROUND: Current knowledge is limited about which manufacturers are active in the global field of biopharmaceutical product development and how many unique follow-on biologics are approved in global markets. OBJECTIVE: This study aimed to provide a cross-sectional overview of manufacturers of follow-on biologics approved in 15 large countries from different regions of the world, as well as in five major biosimilar markets with long established biosimilar frameworks. METHODS: We screened national drug databases to identify follow-on biologics and their manufacturers approved in 15 countries in Asia, Africa, Latin America and the rest of the world, as well as five major biosimilar markets: the European Union (including the UK), USA, Canada, Australia and Japan. RESULTS: This study identified a total of 304 follow-on biologics from different manufacturers for 18 active substance classes included in the analysis. Of these, 67 products are approved as biosimilars in at least one of the five major biosimilar markets. A total of 140 (46%) follow-on biologics are manufactured in India or China, of which only eight (seven from India and one from China) are approved as biosimilars in any of the five major biosimilar markets. This study found that the majority of follow-on biologics are only approved in the respective country of manufacturing. A small number of manufacturers, primarily from India and Argentina, supply their products to other regions in the world. As some countries have less stringent regulatory approaches for biosimilars, or have only recently implemented biosimilar guidance in line with World Health Organization standards, follow-on biologics could have been approved that would not be considered biosimilars according to the World Health Organization standards. CONCLUSIONS: With this study, we try to contribute to discussions on creating more transparency about global approvals of follow-on biologics and promoting access to high-quality biosimilars in countries around the world.

The future of medicines is likely determined by an array of scientific, socioeconomic, policy, medical need, and geopolitical factors, with many uncertainties ahead. Here, we report from a scenario project, analyzing various trends, crucial and complex developments in the medicines' space. From a range of 'critical uncertainties' we derived two scenario drivers: global convergence, ranging from very high (trust and solidarity), to very low (fragmented ecosystems); and disease orientation, ranging from public health first to interceptive medicine. This resulted in four contrasting portraits of the future of medicines and social policy: deprioritizing the high-end; sustainable flow; transformative healing; and global divide. All those involved in drug discovery and development can use these for strengthening preparedness for the crucial challenges ahead.

Containing the COVID-19 pandemic requires rapidly identifying infected individuals. Subtle changes in physiological parameters (such as heart rate, respiratory rate, and skin temperature), discernible by wearable devices, could act as early digital biomarkers of infections. Our primary objective was to assess the performance of statistical and algorithmic models using data from wearable devices to detect deviations compatible with a SARS-CoV-2 infection. We searched MEDLINE, Embase, Web of Science, the Cochrane Central Register of Controlled Trials (known as CENTRAL), International Clinical Trials Registry Platform, and ClinicalTrials.gov on July 27, 2021 for publications, preprints, and study protocols describing the use of wearable devices to identify a SARS-CoV-2 infection. Of 3196 records identified and screened, 12 articles and 12 study protocols were analysed. Most included articles had a moderate risk of bias, as per the National Institute of Health Quality Assessment Tool for Observational and Cross-Sectional Studies. The accuracy of algorithmic models to detect SARS-CoV-2 infection varied greatly (area under the curve 0·52-0·92). An algorithm's ability to detect presymptomatic infection varied greatly (from 20% to 88% of cases), from 14 days to 1 day before symptom onset. Increased heart rate was most frequently associated with SARS-CoV-2 infection, along with increased skin temperature and respiratory rate. All 12 protocols described prospective studies that had yet to be completed or to publish their results, including two randomised controlled trials. The evidence surrounding wearable devices in the early detection of SARS-CoV-2 infection is still in an early stage, with a limited overall number of studies identified. However, these studies show promise for the early detection of SARS-CoV-2 infection. Large prospective, and preferably controlled, studies recruiting and retaining larger and more diverse populations are needed to provide further evidence.

The COVID-19 pandemic required urgency in the development and delivery of effective vaccines and therapeutics; meanwhile, ongoing clinical research, regulation and supply for other much-needed therapeutics and vaccines needed to be sustained. In Europe, the European Commission, the European Medicines Agency (EMA) and the national regulatory agencies (NRAs) responded by issuing guidance outlining regulatory flexibilities mainly directed at COVID-19 vaccines and, belatedly, therapeutics. Using a survey methodology, this study gathered the views of the R&D based pharmaceutical industry in May-June 2021 on the value of these flexibilities for continued use in the post-pandemic era as well as for future use in health emergency situations. Findings indicate that many flexibilities were foreseen to have value beyond the pandemic, particularly where EU and Member States aligned closely to provide a singular, streamlined regulatory environment. Digitalization was a notable driver of these flexibilities, but innovations in regulatory process (e.g. rolling reviews, flexible Scientific Advice) improved the process and outcomes measurably. Finally, the rapid reaction of the EU regulatory system and extensive efforts by all involved in providing innovative therapeutics and vaccines to patients in need provides learnings for the upcoming overhaul of the pharmaceutical acquis.

Aims: Recently, the use of novel remote monitoring technologies (RMTs) in trials has gained much interest. To facilitate regulatory learning, we evaluated qualification opinions (QOs) and advices (QAs) and scientific advices (SAs) of the Committee for Medicinal Products for Human Use (CHMP) to gain insight in the types of devices that are intended to be used in clinical trials for supporting/submitting application for obtaining marketing authorization (registration trials) and the main recommendations of the CHMP. Methods: QOs, QAs, and SAs of the CHMP that assessed RMTs between 2013 and 2019 were eligible for our study. The following information was extracted from the documents: year of advice/opinion, device and endpoints used, type of endpoint (primary, secondary, exploratory, or safety), and main recommendations of the CHMP. Results: In total two QOs, four QAs, and 59 SAs were included in our study (total of SAs between 2013 and 2019 = 4,054). In the SAs, accelerometers to measure activity and/or sleep parameters (n = 31) were the most frequently used devices, followed by mobile applications (n = 6) and glucose monitoring devices (n = 6). Usually, these measures were proposed as secondary or exploratory endpoints (n = 32). The main recommendations of the CHMP were related to relevance of the (novel) outcome measure; validation; precision, accuracy, sensitivity, and specificity; compliance; sampling interval; and data handling and privacy. Conclusions: Although there was a trend toward an increased use over time, the use of RMTs in registration trials is still relatively rare. In the absence of formal European regulatory guidance on mHealth technologies, insight in the main recommendations of the CHMP may stimulate the use of novel RMTs in a regulatory context.
RESUMEN
The continuous scientific, societal, and technological advancements have shifted drug development toward increasingly complex and ever more targeted treatments. This creates new and unprecedented challenges for global regulatory systems. To address the increased risks and uncertainties of increasingly complex medicine, we advocate for a more tailored and flexible regulatory approach, which is explained here with the concept of 'regulatory density'. In the context of this paper, 'regulatory density' describes the relative amount of obligatory standards, measures and procedures applied to certain medicinal products or product classes and the resources required to meet these requirements. Given that risk and uncertainty are dynamic variables that can change over time, with this paper, we want to stimulate (re)thinking of regulatory approaches for managing the challenges of future complex medicines.

BACKGROUND: As regulatory agencies come under increased pressure to review medicines of critical importance through efficient regulatory systems to provide equitable access, the benefits of using expedited review pathways are being explored. These facilitated regulatory pathways (FRPs) provide a variety of review strategies that can also expedite assessments. Stringent regulatory authorities (SRAs) use primary FRPs to accelerate development or to shorten review time. Some emerging national regulatory authorities can implement primary FRPs but are more likely to use secondary FRPs that rely on or recognize an SRA or reference agency decision, the World Health Organization Collaborative Prequalification of Medicines Programme, "altruistic" reviews, or collaborative work sharing. Despite their availability, there are no formal guidelines or consensus for the definition, basic elements, or best practices for FRPs. METHODS: Herein, we present a 4-step pragmatic approach to a framework designed to help agencies determine how best to use FRPs. Each step is based on characteristics identified through research, surveys, literature assessments, regulatory capacity categorization analyses, and practical experience. RESULTS: Step 1 assesses 4 domains of the environment preparedness, step 2 offers process criteria that should be in place to effectively use an FRP, step 3 tiers agencies through a self-assessment of readiness and capacity, and step 4 provides a pathway for agencies to determine the most relevant FRP for their use. Target timelines are proposed for FRPs. CONCLUSIONS: This framework represents the first endeavor to holistically address the multifaceted aspects that should be considered for the effective use of an FRP.

INTRODUCTION: Due to the complexity of biologics and the inherent challenges for manufacturing, it is important to know the specific brand name and batch number of suspected biologics in adverse drug reaction (ADR) reports. OBJECTIVE: The aim of this study was to assess the extent to which biologics are traceable by brand name and batch number in UK hospital practice and in ADRs reported by patients and healthcare professionals. METHODS: We performed an online hospital pharmacist survey to capture information on how specific product details are recorded during the processes of prescribing, dispensing and administration of biologics in routine UK hospital practice. We also assessed the proportion of ADR reports specifying brand name and batch number from electronic ADR reports submitted to the UK national spontaneous reporting database, the Yellow Card Scheme, between 1 January 2009 and 30 September 2017. RESULTS: Brand name recording in routine hospital processes ranged from 79 to 91%, whereas batch numbers were less routinely recorded, ranging from 38 to 58%. Paper-based recording of product details was more commonly used for recording information. A total of 6108 electronic ADR reports were submitted to the Yellow Card Scheme for recombinant biologics, of which 38% and 15%, respectively, had an identifiable brand name and batch numbers. Whereas batch number traceability in electronic ADR reports improved slightly after the implementation of the European Union pharmacovigilance legislation in 2012, no improvement of brand name traceability was observed. CONCLUSION: Brand name and batch number traceability for biologics in UK ADR reports are generally low. Shortcomings in the systematic recording of product details in UK clinical practice may contribute to the limited traceability.

Regulating drugs does not end when market access has been granted. Monitoring drugs over the life cycle has become state of the art, inherent to evolving legislation and societal need. Here, we explore how the drug label could move along in a changing playing-field and become a sustainable label for the future. A dialogue between academia, government, the pharmaceutical industry and patient/societal organizations was organized by the Regulatory Science Network Netherlands. This is their view.

Progress in cell biology, genetics, molecular, and systems pharmacology is the driving force behind a current paradigm shift in drug research. This paradigm shift shapes new avenues for advanced treatments that are commonly referred to as 'systems therapeutics'. Systems therapeutics differ in many ways from current drugs because they target biological networks rather than single transduction pathways, and affect disease processes rather than physiological processes. Here, we examine how the paradigm shift towards systems therapeutics will change current scientific concepts of the interactions between drugs and diseases, the organization of research and development, as well as the clinical use and therapeutic evaluations of therapeutic interventions.

This article provides an overview of the current situation regarding the traceability of medicinal products, with a focus on drug safety and biologics. Limited traceability of biologics, in particular with regard to the batch number, is associated with incomplete recording of exposure information in clinical practice. The current pharmaceutical barcode standards in the EU do not support the automatic recording of dynamic product information, such as batch numbers and expiry dates, by means of electronic barcode scanning in clinical practice. New barcode requirements, such as the 2D DataMatrix with encoded batch numbers and expiry dates, provided on both the primary and the secondary package, can facilitate routine barcode scanning at all points in the supply chain in different healthcare settings. To build a full track-and-trace system for medicines with electronic capture of relevant exposure information, alignment with other topics, such as the Falsified Medicines Directive and initiatives to reduce medication errors, is needed to increase the buy-in from all stakeholders and to solve multiple issues with a joint effort.

Concerns have been expressed that large numbers of nonvalue-added reports have been accumulating in adverse drug reaction (ADR) databases, for example, via patient support programs. We performed an assessment of the impact of such reports, which we refer to as "precautionary reports," on safety signal detection in the Netherlands. The case narratives of ADR reports of three case products were screened with text-mining algorithms to identify those reports that lack a causal relationship with the suspected medicinal product. We demonstrate that precautionary reports impede the optimal use of the pharmacovigilance system by, on the one hand, masking safety signals and, on the other hand, creating spurious signals. The precautionary reporting bias and its suppressing effect on statistical signal detection results in an altered adverse event safety profile. The findings from this study highlight the need for a better alignment between regulatory authorities and marketing authorization holders regarding pharmacovigilance guidelines.

The US Food and Drug Administration (FDA) has four facilitated regulatory pathways (FRPs): Fast Track (FT), Breakthrough Therapy (BTD), Priority Review (PR), and Accelerated Approval (AA). Only PR specifies an expedited review timeline (6 months). We sought to determine to what extent the combination of two or more FRPs influenced development and approval times. We developed a "metro map" to illustrate FRP elements and their influence on review times. We assessed 125 new active substances (approved January 2013 to December 2015) 74 of which used one or more FRPs. For these 74, development times ranged from 1,458 (BTD + PR + AA) to 3,515 days (PR). PR alone had a median approval time of 242 days. The most common combination was FT + PR (median approval 292 days, n = 21). The fastest approval times were for PR + FT + BTD + AA (145 days) and PR + BTD + AA (166 days). Our findings support the combination of FRPs for shortening development and review times beyond that provided by PR alone.
RESUMEN
There is growing interest in characterising factors associated with positive regulatory outcomes for drug marketing authorisations. We assessed empirical studies published over the past 15 years seeking to identify predictive factors. Factors were classified to one of four 'factor clusters': evidentiary support; product or indication characteristics; company experience or strategy; social and regulatory factors. We observed a heterogeneous mix of technical factors (e.g., study designs, clinical evidence of efficacy) and less studied social factors (e.g., company-regulator interactions). We confirmed factors known to be of relevance to drug approval decisions (imperative) and a cohort of less understood (compensatory) social factors. Having robust supportive clinical evidence, addressing rare or serious illness, following scientific advice and prior company experience were associated with positive outcomes, which illustrated the multifactorial nature of regulatory decision making and factors need to be considered holistically while having varying, context-dependent importance.

OBJECTIVES: To illustrate how pragmatic trial design elements or inserting explanatory trial elements in pragmatic trials affect validity, generalizability, precision, and operational feasibility. STUDY DESIGN AND SETTING: From illustrative examples identified through the IMI Get Real Consortium, we selected randomized drug trials with a pragmatic design feature. We searched all publications on these trials for information on how pragmatic trial design features affect validity, generalizability, precision, or feasibility. RESULTS: We present examples from the Salford lung study, International Suicide Prevention Trial, Sequenced Treatment Alternatives to Relieve Depression, and Cluster Randomized Usual care vs. Caduet Investigation Assessing Long-term-risk trial. These examples show that incorporating pragmatic trial design elements in trials may affect generalizability, precision and validity and may lead to operational challenges different from traditional explanatory trials. Inserting explanatory trial elements into pragmatic trials may also affect validity, generalizability, and operational feasibility, especially when these trial elements are incorporated in one arm of the trial only. Design choices that positively affect one of these domains (e.g., generalizability) may negatively affect others (e.g., feasibility). CONCLUSION: Consequences of incorporating pragmatic or explanatory trial design elements in pragmatic trials should be explicitly considered and balanced for all relevant domains, including validity, generalizability, precision, and operational feasibility. Tools are needed to make these consequences more transparent.

OBJECTIVES: We assessed the characteristics of currently implemented expedited (facilitated) regulatory pathways (FRPs) used by national regulatory authorities (NRAs) in emerging economies to speed access to important new medicines. METHODS: We identified NRAs with FRPs through Thomson Reuters Cortellis Regulatory Intelligence and through agency Websites. We developed a list of 27 FRP characteristics. We categorised characteristics as procedural or substantive and based them on five sequential regulatory activities. FINDINGS: We assessed 29 countries with 33 FRPs. The regions with the characteristics described most extensively by their FRPs were the Middle East/North Africa and Eastern Europe. The Sub-Saharan African region included the FRPs that were least specific in describing characteristics. Overall, FRPs presented at least twice as many procedural as substantive characteristics. CONCLUSIONS: We observed diversity by region in FRP characteristics, suggesting a role for further engagement with emerging NRAs in their design and implementation. Common processes could advance regulatory alignment initiatives and help the WHO inform the development of novel, globally aligned accelerated development and regulatory pathways for products that fulfil serious unmet public health needs.Journal of Public Health Policy advance online publication, 10 March 2016; doi:10.1057/jphp.2016.8.
RESUMEN
INTRODUCTION AND OBJECTIVE: Pharmacovigilance requirements for biologics mandate that EU Member States shall ensure that any biologic that is the subject of a suspected adverse drug reaction (ADR) is identifiable by brand name and batch number. Recent studies showed that brand name identification is well established, whereas batch numbers are (still) poorly reported. We evaluated information-recording systems and practices in the Dutch hospital setting to identify determinants for brand name and batch number recording as well as success factors and bottlenecks for traceability. METHODS: We surveyed Dutch hospital pharmacists with an online questionnaire on systems and practices in hospitals for recording brand names and batch numbers. Additionally, we performed an analysis of the traceability of recombinant biologics in spontaneous ADR reports (received between 2009 and 2014) from the Netherlands Pharmacovigilance Centre Lareb. RESULTS: The survey showed that brand names are not routinely recorded in the clinical practice of Dutch hospitals, whereas batch numbers are poorly recorded. Seventy-six percent of the 1523 ADR reports for recombinant biologics had a traceable brand name whereas 5% of these reports contained a batch number. The results suggest a possible relationship between the availability of brand and batch number information in clinical practice and the inclusion of this information in ADR reports for biologics. CONCLUSION: The limited traceability of brand names and batch numbers in ADR reports may be primarily caused by the shortcomings in the recording of information in clinical practice. We recommend efforts to improve information-recording systems as a first step to improve the traceability of biologics in ADR reporting.

BACKGROUND AND OBJECTIVE: Biological medicinal products (biologics) are subject to specific pharmacovigilance requirements to ensure that biologics are identifiable by brand name and batch number in adverse drug reaction (ADR) reports. Since Member States collect ADR data at the national level before the data is aggregated at the European Union (EU) level, it is important that an unambiguous understanding of which medicinal products belong to the biological product category exists. This study aimed to identify the level of consistency between Member States regarding the classification of biologics by national authorities responsible for ADR reporting. METHODS: A sample list of recombinant biologics from the European Medicines Agency database of European Public Assessment Reports was created to analyze five Member States (Belgium, the Netherlands, Spain, Sweden, and the UK) according to which products were classified as biologics by each Member State. We calculated the Fleiss kappa value to analyze interrater reliability. RESULTS: A considerable divergence was identified regarding the classification of the 146 recombinant biologics from the sample list: one Member State classified 100 % of the recombinant biologics from the sample list as biologics, whereas the classification rates in the remaining four Member States ranged between 70 and 88 % for products available on the national market. The interrater reliability for 87 products available on the market in all five Member States was considered poor. CONCLUSION: Discrepancies exist between Member States in the classification of biologics; less divergence exists for common well-known biologics. These findings highlight the need to think about the best approaches to translate EU legislation into national practices. Additionally, we recommend a publicly available and frequently updated list of centrally authorized biologics.

BACKGROUND: Guidance and exploratory evidence indicate that the type of endpoints and the magnitude of their outcome can define a therapy's clinical activity; however, little empirical evidence relates specific endpoint properties with regulatory outcomes. MATERIALS AND METHODS: We explored the relationship of 3 endpoint properties to regulatory outcomes by assessing 50 oncology marketing authorization applications (MAAs; reviewed from 2009 to 2013). RESULTS: Overall, 16 (32%) had a negative outcome. The most commonly used hard endpoints were overall survival (OS) and the duration of response or stable disease. OS was a component of 91% approved and 63% failed MAAs. The most commonly used surrogate endpoints were progression-free survival (PFS), response rate, and health-related quality of life assessments. There was no difference (p = .3801) between the approved and failed MAA cohorts in the proportion of hard endpoints used. A mean of slightly more than four surrogate endpoints were used per approved MAA compared with slightly more than two for failed MAAs. Longer OS and PFS duration outcomes were generally associated with approvals, often when not statistically significant. The approved cohort was associated with a preponderance of statistically significant (p < .05) improvements in primary endpoints (p < .0001 difference between the approved and failed groups). CONCLUSION: Three key endpoint properties (type of endpoint [hard/surrogate], magnitude of an endpoint outcome, and its statistical significance) are consistent with the European Medicines Agency guidance and, notwithstanding the contribution of unique disease-specific circumstances, are associated with a predictable positive outcome for oncology MAAs. IMPLICATIONS FOR PRACTICE: Regulatory decisions made by the European Medicines Agency determine which new medicines will be available to European prescribers and for which therapeutic indications. Regulatory success or failure can be influenced by many factors. This study assessed three key properties of endpoints used in preauthorization trials (type of endpoint [hard/surrogate], magnitude of endpoint outcome, and its statistical significance) and whether they are associated with a positive regulatory outcome. Clinicians can use these properties, which are described in the publicly available European public assessment reports, to help guide their understanding of the clinical effect of new oncologic therapies.
