The Impact of the COVID-19 Pandemic on the Future of Science Careers.

As COVID-19 swept across the world, it created a global pandemic and an unpredictable and challenging job market. This article discusses the future of the 2020-2021 job market in both academia and industry in the midst and aftermath of this pandemic.

Current Practice for Therapeutic Drug Monitoring of Biopharmaceuticals in Spondyloarthritis.

Treatment of spondyloarthritis (SpA) has greatly improved in the biopharmaceutical era. These compounds, primarily tumor necrosis factor inhibitors, are effective, but some patients may show poor response, sometimes due to the presence of antidrug antibodies (ADAs). In some instances, clinicians may increase or taper the dose, depending on the clinical response. Besides the current clinical practice, a tailored strategy based on drug monitoring is emerging as a way to improve the use of these drugs. However, the relevance of this therapeutic drug monitoring of biopharmaceuticals for SpA is still unknown. In this literature review, we examined the most relevant articles dealing with the concentration-response relation, ADA detection, and pharmacokinetics in SpA treated with biopharmaceuticals. ADAs were associated with low or undetectable concentration of monoclonal antibodies. The relation between drug concentration and clinical response in SpA is debated, some studies showing an association and others not. Therefore, therapeutic drug monitoring of biopharmaceuticals for SpA requires a better understanding of the association among the pharmacokinetics, pharmacodynamics, and immunogenicity of these drugs.

Current Practice of Therapeutic Drug Monitoring of Biopharmaceuticals in Psoriasis Patients.

The high prevalence of psoriasis and the high spending on pharmaceuticals motivate a more evidence-based and cost-effective usage of biopharmaceuticals. A growing body of evidence exists that the implementation of therapeutic drug monitoring for biopharmaceuticals in psoriasis patients optimizes patient management and clinical outcome and enhances their efficacy. Therefore, the aim of this review was to give an overview of the literature on therapeutic drug monitoring of biopharmaceuticals in the treatment of psoriasis and to provide the useful information to dermatologists to improve health care in psoriasis patients.

Current Practice for Therapeutic Drug Monitoring of Biopharmaceuticals in Rheumatoid Arthritis.

The treatment of rheumatoid arthritis (RA) has largely improved in the biopharmaceutical era. These compounds, primarily tumor necrosis factor (TNF) inhibitors, are effective, but some patients may show poor response, sometimes because of the presence of antidrug antibodies (ADAs). In some instances, clinicians may increase or taper the dose depending on the clinical response. Besides the current clinical-based practice, a tailored strategy based on drug monitoring has emerged as a way to improve the use of these drugs. However, the relevance of this therapeutic drug monitoring (TDM) of biopharmaceuticals in RA is still unknown. In this literature review, we examine the most relevant articles dealing with the concentration-response relationship, ADA detection and pharmacokinetics in RA patients receiving biopharmaceuticals. A concentration-response relationship was clearly established for TNF inhibitors. Moreover, ADA positivity was associated with low drug concentrations, poor clinical outcome, and reduced drug survival for TNF-inhibitor monoclonal antibodies. Concomitant use of disease-modifying antirheumatic drugs, especially methotrexate, is associated with good clinical outcome, increased drug concentrations, and reduced immunogenicity. Strategies based on TDM of TNF inhibitors seem promising for RA, but randomized controlled trials are required to support this. A concentration-response relationship may exist with tocilizumab, and immunogenicity seems rare. Finally, the relevance of TDM for RA patients receiving rituximab and abatacept remains unclear.

The transgenic animal platform for biopharmaceutical production.

The recombinant production of therapeutic proteins for human diseases is currently the largest source of innovation in the pharmaceutical industry. The market growth has been the driving force on efforts for the development of new therapeutic proteins, in which transgenesis emerges as key component. The use of the transgenic animal platform offers attractive possibilities, residing on the low production costs allied to high productivity and quality of the recombinant proteins. Although many strategies have evolved over the past decades for the generation of transgenic founders, transgenesis in livestock animals generally faces some challenges, mainly due to random transgene integration and control over transgene copy number. But new developments in gene editing with CRISPR/Cas system promises to revolutionize the field for its simplicity and high efficiency. In addition, for the final approval of any given recombinant protein for animal or human use, the production and characterization of bioreactor founders and expression patterns and functionality of the proteins are technical part of the process, which also requires regulatory and administrative decisions, with a large emphasis on biosafety. The approval of two mammary gland-derived recombinant proteins for commercial and clinical use has boosted the interest for more efficient, safer and economic ways to generate transgenic founders to meet the increasing demand for biomedical proteins worldwide.

Clinical development and trial design of biosimilar products: a Japanese perspective.

In recent years, development of biosimilar products has attracted considerable attention. Because of the structural complexity of biologics, it is difficult to demonstrate that a biosimilar product is identical to the reference product. Therefore, for the development of biosimilar products, we need to adopt an approach that is different from generic product development. In this article, we discuss the guidelines for the development of biosimilar products along with the case examples of biosimilar product development in Japan. In addition, we discuss several issues of clinical trial design for demonstrating biosimilarity to a reference product.

Biosimilars: where we were and where we are.

Recent progress in biosimilars development is overviewed, with attention to the history of issues and processes leading to current regulations, and to scientific considerations, including progress on design and operational implementation issues that arise and are peculiar to biosimilars trial design and implementation.

Emergence of biopharmaceutical innovators in China, India, Brazil, and South Africa as global competitors and collaborators.

Biopharmaceutical innovation has had a profound health and economic impact globally. Developed countries have traditionally been the source of most innovations as well as the destination for the resulting economic and health benefits. As a result, most prior research on this sector has focused on developed countries. This paper seeks to fill the gap in research on emerging markets by analyzing factors that influence innovative activity in the indigenous biopharmaceutical sectors of China, India, Brazil, and South Africa. Using qualitative research methodologies, this paper a) shows how biopharmaceutical innovation is taking place within the entrepreneurial sectors of these emerging markets, b) identifies common challenges that indigenous entrepreneurs face, c) highlights the key role played by the state, and d) reveals that the transition to innovation by companies in the emerging markets is characterized by increased global integration. It suggests that biopharmaceutical innovators in emerging markets are capitalizing on opportunities to participate in the drug development value chain and thus developing capabilities and relationships for competing globally both with and against established companies headquartered in developed countries.

Experimental models for the investigation of high-density lipoprotein-mediated cholesterol efflux.

Reduction of low-density lipoprotein cholesterol by statin therapy has only modestly decreased coronary heart disease (CHD)-associated mortality in developed countries, which has prompted the search for alternative therapeutic strategies for CHD. Epidemiologic and interventional studies have clearly established an inverse association between plasma levels of high-density lipoprotein (HDL) cholesterol and incidence of atherosclerosis. The atheroprotective benefits of HDL are not only dependent on HDL concentrations (quantity), but also on HDL function (quality). Therefore, several techniques have been recently developed to assess the different properties of HDL. Because reverse cholesterol transport (RCT) is considered a key player in the beneficial action of HDL, this review focuses on the different methods used to evaluate cholesterol efflux. Measuring the in vivo function of HDL could be of significant importance for both the clinical evaluation of an individual patient and to evaluate the effectiveness of different RCT-enhancing therapeutic approaches.

Progress in phage display: evolution of the technique and its application.

Phage display, the presentation of (poly)peptides as fusions to capsid proteins on the surface of bacterial viruses, celebrates its 25th birthday in 2010. The technique, coupled with in vitro selection, enables rapid identification and optimization of proteins based on their structural or functional properties. In the last two decades, it has advanced tremendously and has become widely accepted by the scientific community. This by no means exhaustive review aims to inform the reader of the key modifications in phage display. Novel display formats, innovative library designs and screening strategies are discussed. I will also briefly review some recent uses of the technology to illustrate its incredible versatility.

Analysis, biomedicine, collaboration, and determinism challenges and guidance: wish list for biopharmaceuticals on the interface of computing and statistics.

I have personally witnessed processing advance from desk calculators and mainframes, through timesharing and PCs, to supercomputers and cloud computing. I have also witnessed resources grow from too little data into almost too much data, and from theory dominating data into data beginning to dominate theory while needing new theory. Finally, I have witnessed problems advance from simple in a lone discipline into becoming almost too complex in multiple disciplines, as well as approaches evolve from analysis driving solutions into solutions by data mining beginning to drive the analysis itself. How we do all of this has transitioned from competition overcoming collaboration into collaboration starting to overcome competition, as well as what is done being more important than how it is done has transitioned into how it is done becoming as important as what is done. In addition, what or how we do it being more important than what or how we should actually do it has shifted into what or how we should do it becoming just as important as what or how we do it, if not more so. Although we have come a long way in both our methodology and technology, are they sufficient for our current or future complex and multidisciplinary problems with their massive databases? Since the apparent answer is not a resounding yes, we are presented with tremendous challenges and opportunities. This personal perspective adapts my background and experience to be appropriate for biopharmaceuticals. In these times of exploding change, informed perspectives on what challenges should be explored with accompanying guidance may be even more valuable than the far more typical literature reviews in conferences and journals of what has already been accomplished without challenges or guidance. Would we believe that an architect who designs a skyscraper determines the skyscraper's exact exterior, interior and furnishings or only general characteristics? Why not increase dependability of conclusions in genetics and translational medicine by enriching genetic determinism with uncertainty? Uncertainty is our friend if exploited or potential enemy if ignored. Genes design proteins, but they cannot operationally determine all protein characteristics: they begin a long chain of complex events occurring many times via intricate feedbacks plus interactions which are not all determined. Genes influence proteins and diseases by just determining their probability distributions, not by determining them. From any sample of diseased people, we may more successfully infer gene probability distributions than genes themselves, and it poses an issue to resolve. My position is supported by 2-3 articles a week in ScienceDaily, 2011.

Survey results on the use of the tissue cross-reactivity immunohistochemistry assay.

A multinational pharmaceutical and biotechnology company survey was conducted to gain a better understanding of the use and value of the tissue cross-reactivity (TCR) assay in the development of biotherapeutic molecules. The majority of the molecules did not use TCR data as the only basis for determining species selection for toxicity studies (73%). For 95% of the molecules, the TCR data had no impact on the development strategy. For 2% of the molecules (1/56), TCR data was the sole source of information indicating a potential risk to patients. Unexpected or off-target binding was seen with 35% of the molecules, with the majority of this binding occurring in the CNS and reproductive organs. Tissues that were known or presumed to contain the target stained positively in 22% and 10% of molecules tested in non-human primate and human tissues, respectively. Tissues that were known or presumed to lack the target were negative for staining in 39% and 50% of molecules for non-human primate and human tissue, respectively. For 5% (6/110) of all the molecules, companies stated that toxicities would have been missed in animal studies or the clinic (i.e., not identified by clinical signs, histopathology, etc.) if the TCR studies had not been performed.

Engineering microbial factories for synthesis of value-added products.

Microorganisms have become an increasingly important platform for the production of drugs, chemicals, and biofuels from renewable resources. Advances in protein engineering, metabolic engineering, and synthetic biology enable redesigning microbial cellular networks and fine-tuning physiological capabilities, thus generating industrially viable strains for the production of natural and unnatural value-added compounds. In this review, we describe the recent progress on engineering microbial factories for synthesis of valued-added products including alkaloids, terpenoids, flavonoids, polyketides, non-ribosomal peptides, biofuels, and chemicals. Related topics on lignocellulose degradation, sugar utilization, and microbial tolerance improvement will also be discussed.

Pharmaceutical strategies in the emerging era of antibody-based biotherapeutics for the treatment of cancers overexpressing MET receptor tyrosine kinase.

Pharmaceutical innovation in the development of novel antibody-based biotherapeutics with increased therapeutic indexes makes MET-targeted cancer therapy a clinical reality.

From drug delivery systems to drug release, dissolution, IVIVC, BCS, BDDCS, bioequivalence and biowaivers.

This is a summary report of the conference on drug absorption and bioequivalence issues held in Titania Hotel in Athens (Greece) from the 28(th) to the 30(th) of May 2009. The conference included presentations which were mainly divided into three sections. The first section focused on modern drug delivery systems such as polymer nanotechnology, cell immobilization techniques to deliver drugs into the brain, nanosized liposomes used in drug eluting stents, encapsulation of drug implants in biocompatible polymers, and application of differential scanning calorimetry as a tool to study liposomal stability. The importance of drug release and dissolution were also discussed by placing special emphasis on camptothecins and oral prolonged release formulations. The complexity of the luminal environment and the value of dissolution in lyophilized products were also highlighted. The second session of the conference included presentations on the Biopharmaceutics Classification Scheme (BCS), the Biopharmaceutics Drug Disposition Classification System (BDDCS), and the role of transporters in the classification of drugs. The current status of biowaivers and a modern view on non-linear in vitro-in vivo (IVIVC) correlations were also addressed. Finally, this section ended with a special topic on biorelevant dissolution media and methods. The third day of the conference was dedicated to bioequivalence. Emphasis was placed on high within-subject variability and its impact on study design. Two unresolved issues of bioequivalence were also discussed: the use of generic antiepileptic drugs and the role of metabolites in bioequivalence assessment. Finally, the conference closed with a presentation of the current regulatory status of WHO and EMEA.

Current status and future opportunities for incorporation of dissolution data in PBPK modeling for pharmaceutical development and regulatory applications: OrBiTo consortium commentary.

In vitro dissolution experiments are used to qualitatively assess the impact of formulation composition and process changes on the drug dosage form performance. However, the use of dissolution data to quantitatively predict changes in the absorption profile remains limited. Physiologically-based Pharmacokinetic(s) (PBPK) models facilitate incorporation of in vitro dissolution experiments into mechanistic oral absorption models to predict in vivo oral formulation performance, and verify if the drug product dissolution method is biopredictive or clinically relevant. Nevertheless, a standardized approach for using dissolution data within PBPK models does not yet exist and the introduction of dissolution data in PBPK relies on a case by case approach which accommodates from differences in release mechanism and limitations to drug absorption. As part of the Innovative Medicines Initiative (IMI) Oral Biopharmaceutics Tools (OrBiTo) project a cross-work package was set up to gather a realistic understanding of various approaches used and their areas of applications. This paper presents the approaches shared by academic and industrial scientists through the OrBiTo project to integrate dissolution data within PBPK software to improve the prediction accuracy of oral formulations in vivo. Some general recommendations regarding current use and future improvements are also provided.

Biopharmaceutical innovation and industrial developments in South Korea, Singapore and Taiwan.

South Korea, Singapore and Taiwan are well known as export-oriented developmental states which for decades employed industrial policy to target particular industries for government support. In the past fifteen years, these three countries all identified the biopharmaceutical industry as a strategic sector. This article explores, through economic analysis, the rationale for this decision and the strategies chosen for linking into the global bio-economy with the objective of catching up in biopharmaceuticals. The paper identifies three comparative advantages enjoyed by these countries in the biopharma sector: (1) public investments in basic research; (2) private investments in phase 1 clinical trials; and (3) a potentially significant contract research industry managing latter-stage clinical trials. Governments employ a range of industrial policies, consistent with these comparative advantages, to promote the biopharmaceutical industry, including public investment in biomedical hubs, research funding and research and development (R&D) tax credits. We argue that the most important feature of the biopharmaceutical industry in these countries is the dominant role of the public sector. That these countries have made progress in innovative capabilities is illustrated by input measures such as R&D expenditure as share of gross domestic product, number of patents granted and clinical trials, and volume of foreign direct investment. In contrast, output indicators such as approval of new chemical entities suggest that the process of catching up has only just commenced. Pharmaceutical innovation is at the stage of mainly generating inputs to integrated processes controlled by the globally incumbent firms.

Continuous In-Line Virus Inactivation for Next Generation Bioprocessing.

Viral inactivation plays a critical role in assuring the safety of monoclonal antibody (mAb) therapeutics. Traditional viral inactivation involves large holding tanks in which product is maintained at a target low pH for a defined hold time, typically 30-60 min. The drive toward continuous processing and improved facility utilization has provided motivation for development of a continuous viral inactivation process. To this end, a lab-scale prototype viral inactivation system was designed, built, and characterized. Multiple incubation chamber designs are evaluated to identify the optimal design that enables narrow residence time distributions in continuous flow systems. Extensive analysis is conducted supporting rapid low pH viral inactivation and included evaluations with multiple viruses, a range of pH levels, buffer compositions, mAb concentrations, and temperatures. Multiple test conditions are evaluated using the in-line system and results compared to traditional batch-mode viral inactivation. Comparability in kinetics of virus inactivation suggests equivalency between the two approaches.

[Transition of the Field from Biochemical Engineering to Pharmaceutical Sciences during 40 Years of the Research].

This review reflects back over almost 40 years of the author's basic research conducted at Graduate School of Pharmaceutical Sciences, Osaka University, Japan. After performing postdoctoral research in USA, the author became a research associate at Prof. Yoshiharu Miura's lab and started research on Biochemical Engineering in 1984. At that time, the main research purpose was to solve global environmental issues for maintaining human health. The author's achievements included novel useful material production system under inorganic conditions and genetically engineered whole-cell bacterial sensors detecting arsenite by naked eye without a detecting device. Another theme in the lab was to construct bioartificial liver support system. Various scaffolds for hepatocytes were newly prepared for constructing the compact reactor. Besides the bioreactor study, the author conducted cell transplantation research for the treatment of chronic liver diseases. It was shown that mesenchymal stem cells derived from third molars (wisdom teeth) could differentiate into hepatocytes and exhibit therapeutic effects in liver-damaged animals. After 2006, the lab started research on drug delivery systems, including noninvasive delivery of drugs such as peptides and nucleic acids by regulating epithelial tight junctions. Many substances enabling drug delivery through "paracellular" route were newly prepared. The author started basic research on Biochemical Engineering in the 1970s. Although these studies eventually shifted into the pharmaceutical field, the underlying concept was based on "engineering" throughout a 40-year research period. The author cordially thanks all colleagues for supporting engineering research in our lab.
