Ethics and regulatory considerations for the clinical translation of somatic cell human epigenetic editing.

Altering the human epigenome with gene-editing technology in attempt to treat a variety of diseases and conditions seems scientifically feasible. We explore some of the ethical and regulatory issues related to the clinical translation of human epigenetic editing arguing that such approaches should be considered akin to somatic therapies.

Ethical, Legal, and Social Issues (ELSI) in Clinical Genetics Research.

ELSI (Ethical, Legal, and Social Issues) is a widely used acronym in the bioethics literature that encompasses a broad range of research examining the various impacts of science and technology on society. In Canada, GE3LS (Genetics, Ethical, Economic, Environmental, Legal, Social issues) is the term used to describe ELSI studies in the context of genetics and genomics research. It is intentionally more expansive in that GE3LS explicitly brings economic and environmental issues under its purview. ELSI/GE3LS research is increasingly relevant in recent years as there has been a greater emphasis on "translational research" that moves genomic discoveries from the bench to the clinic. The purpose of this chapter is to outline a range of ELSI-related work that might be conducted as part of a large scale genetics or genomics research project, and to provide some practical insights on how a scientific research team might incorporate a strong and effective ELSI program within its broader research mandate. We begin by describing the historical context of ELSI research and the development of GE3LS research in the Canadian context. We then illustrate how some ELSI research might unfold by outlining a variety of GE3LS research questions or content domains and the methodologies that might be employed in studying them. We conclude with some practical suggestions about how to build an effective ELSI/GE3LS team and focus within a broader scientific research program.

Evidence-Based Decision-Making 8: A Primer on Health Policy for Researchers.

There is a growing expectation that research will be used to inform decision-making. It is important for researchers to understand how health policy is developed and the different ways they can influence the development of policy.Public policy is developed to resolve identified problems. Health policy is a subset of public policy and is typically concerned with issues related to the health of populations either from a service delivery perspective or from a broader public health and social determinants of health perspective. The policy planning algorithm is well established and follows the basic decision-making framework: problem identification, policy formulation, implementation, and evaluation. A variety of government and nongovernment stakeholders engage in complex debates to identify and resolve policy issues. In this chapter, we explore how researchers can use their research to influence the development of health policy. Knowledge translation strategies focused on communicating research to policy-makers require considerable thought and planning.

Strengthening regulatory science in academia: STARS, an EU initiative to bridge the translational gap.

Truly disruptive medicine innovation and new treatment paradigms tend to start in non-commercial research institutions. However, the lack of mutual understanding between medicine developers and regulators when it comes to medicine development significantly delays or even prevents the access of patients to these innovations. Here, we outline what regulatory-related barriers hamper the translational development of novel products or new treatment paradigms initiated in academia, and propose key steps towards improved regulatory dialogue among academia, funding bodies and regulatory authorities. Moreover, we briefly describe how the STARS (Strengthening Training of Academia in Regulatory Science) project aims to reach out to medicine innovators in academia to bridge the regulatory knowledge gap and enhance this dialogue to facilitate the implementation of academic research findings in clinical practice.

Tradition, not science, is the basis of animal model selection in translational and applied research.

National and international laws and regulations exist to protect animals used for scientific purposes in translational and applied research, which includes drug development. However, multiple animal models are available for each disease. We evaluated the argumentation behind the selection of a specific animal model using thematic content analysis in project applications issued in 2017-2019 in the Netherlands. In total, 125 animal models for translational and applied research from 110 project applications were assessed. Explanations to select a specific model included: the model's availability (79%); the availability of expertise (62%); and the model showing similar disease pathology/symptoms (59%) to humans. Therefore, current selection of a specific animal model seems to be based on tradition rather than its potential predictive value for clinical outcome. The applicants' explanations for the implementation of the 3R prin­ciples (replacement, reduction and refinement) as to the animal model were unspecific. Replacement was achieved by using data from prior in vitro studies, reduction by optimal experimental design and statistics, and refinement by reducing discomfort. Additionally, due to the stated need for a test model with high complexity (47%) and intactness (30%), the full replacement of animal models with alternative (non-live animal) approaches was thought unachievable. Without a clear, systematic and transparent justification for the selection of a specific animal model, the likelihood of poorly trans­latable research remains. It is not only up to the researcher to demonstrate this, as ethical committees and funding bodies can provide positive stimuli to drive this change.

The Progression of Regenerative Medicine and its Impact on Therapy Translation.

Despite regenerative medicine (RM) being one of the hottest topics in biotechnology for the past 3 decades, it is generally acknowledged that the field's performance at the bedside has been somewhat disappointing. This may be linked to the novelty of these technologies and their disruptive nature, which has brought an increasing level of complexity to translation. Therefore, we look at how the historical development of the RM field has changed the translational strategy. Specifically, we explore how the pursuit of such novel regenerative therapies has changed the way experts aim to translate their ideas into clinical applications, and then identify areas that need to be corrected or reinforced in order for these therapies to eventually be incorporated into the standard-of-care. This is then linked to a discussion of the preclinical and postclinical challenges remaining today, which offer insights that can contribute to the future progression of RM.

Ethical, Legal and Regulatory Issues of Paediatric Translational Research. Call for an Adequate Model of Governance.

The lack of paediatric medicines, including innovative and advanced ones, is a long-lasting and well-known problem at European and international levels. Despite the existing legal frameworks and incentives, children remain deprived of many kinds of therapy because of challenges faced in appropriately study and tailoring medicinal and other products for them. In this context, the necessity to foster paediatric research addressing unsolved and uncovered issues within a 'translational approach' has appeared. This article, after having clarified the concept of translational research in the perspective of the establishment of a European paediatric research infrastructure (RI), will identify and point out ethical, legal and regulatory issues particularly relevant in a children's rights perspective. It concludes asking for the setting up of an adequate model of governance within a future RI, including adequate and independent ethical oversight and a pluridisciplinary common service dealing with ethical, legal and societal issues relevant for children.

Translating Immuno-oncology Biomarkers to Diagnostic Tests: A Regulatory Perspective.

The rapid development of effective immunotherapy using immune-checkpoint inhibitors (ICIs) against many different cancer types opened a new front in cancer treatment. Immunotherapy is undoubtedly one of the biggest breakthroughs in cancer therapy within the past decade. The identification of predictive biomarkers to select the patients most likely to respond to ICI monotherapies or emerging combination therapies remains one of the major unmet needs for the oncology community.This chapter provides an overview of existing and emerging biomarkers associated with ICI response. Additionally, using several case studies of FDA approved or authorized in vitro diagnostic oncology devices, this chapter also provides an overview of analytical and clinical validation considerations of diagnostic tests for immuno-oncology biomarkers.

A few ethical issues in translational research for gene and cell therapy.

BACKGROUND: Although translational research for drug development can provide patients with valuable therapeutic resources it is not without risk, especially in the early-phase trials that present the highest degree of uncertainty. With the extraordinary evolution of biomedical technologies, a growing number of innovative products based on human cells and gene therapy are being tested and used as drugs. Their use on humans poses several challenges. METHODS: In this work, we discuss some ethical issues related to gene and cell therapies translational research. We focus on early-phase studies analysing the regulatory approach of Europe and the United States. We report the current recommendations and guidelines of international scientific societies and European and American regulatory authorities. RESULTS: The peculiarity of human cell- or tissue-based products and gene therapy has required the development of specific regulatory tools that must be continually updated in line with the progress of the research. The ethics of translational research for these products also requires further considerations, particularly with respect to the specificity of the associated risk profiles. CONCLUSIONS: An integrated ethical approach that aims for transparency and regulation of development processes, the support of independent judgment in clinical trials and the elimination of unregulated and uncontrolled grey areas of action are necessary to move gene and cell therapy forward.

Prioritizing research challenges and funding for allergy and asthma and the need for translational research-The European Strategic Forum on Allergic Diseases.

The European Academy of Allergy and Clinical Immunology (EAACI) organized the first European Strategic Forum on Allergic Diseases and Asthma. The main aim was to bring together all relevant stakeholders and decision-makers in the field of allergy, asthma and clinical Immunology around an open debate on contemporary challenges and potential solutions for the next decade. The Strategic Forum was an upscaling of the EAACI White Paper aiming to integrate the Academy's output with the perspective offered by EAACI's partners. This collaboration is fundamental for adapting and integrating allergy and asthma care into the context of real-world problems. The Strategic Forum on Allergic Diseases brought together all partners who have the drive and the influence to make positive change: national and international societies, patients' organizations, regulatory bodies and industry representatives. An open debate with a special focus on drug development and biomedical engineering, big data and information technology and allergic diseases and asthma in the context of environmental health concluded that connecting science with the transformation of care and a joint agreement between all partners on priorities and needs are essential to ensure a better management of allergic diseases and asthma in the advent of precision medicine together with global access to innovative and affordable diagnostics and therapeutics.

DOHaD - the challenge of translating the science to policy.

The DOHaD Society has passed its 10th birthday, so it seems an appropriate time to reflect on what has been achieved and the Society's aspirations. At the 10th International Congress in Rotterdam in November 2017, Peter Gluckman (the Society's first President) delivered a plenary lecture entitled 'DOHaD - addressing the science-policy nexus: a reality check'; in opening the Congress, Mark Hanson (second, and outgoing President) not only highlighted the success of the Society but also the challenges it now faces in achieving impact for its work in the global health arena, that is beyond the research agenda; and in assuming the role of third President, Lucilla Poston highlighted the need for the Society to grasp opportunities to change healthcare policy, while persevering with basic research and well-planned intervention studies. In this review we summarize the points made in these three presentations and issue a call to action to the membership to take up the challenge of taking the Society's work to the next level of translating science to policy.

Clinical translation of theranostic radiopharmaceuticals: Current regulatory status and recent examples.

With the development of ever more radiopharmaceuticals suitable for theranostic applications, translation of novel compounds from the preclinical stage towards clinical application becomes a bottleneck for the advances in Nuclear Medicine. This review article summarizes the current regulatory framework for clinical trials with radiopharmaceuticals in the European Union, provides a general overview of the documentation required, and addresses quality, safety, and clinical aspects to be considered. By using a recent successful example of translating a theranostic peptide radioligand, namely 111 In-CP04, which targets receptors expressed in medullary thyroid carcinoma, the pathway from the preclinical development over establishing the required pharmaceutical documentation to designing and submitting a clinical trial is reviewed. Details regarding preclinical data, generation of the documentation, and final successful application are described. This article should provide an insight in an ever more complex process to bring innovations in the field of radiopharmaceuticals into patients.

Biospecimens, Research Consent, and Distinguishing Cell Line Research.

Newly revised regulations for human research affecting translational oncology will become effective in January 2019. A substantial component of the debate leading to this revision was how to regulate biospecimen research; specifically, whether all biospecimens should be considered inherently "identifiable," thereby necessitating informed consent for use in research. The famous cases seminal to this discussion involve cancer cell lines, but the unique features of this kind of biospecimen research were largely missing from the regulatory deliberation. However, special aspects of cell line research-at the stages of procurement, generation, evolution, and sharing-alter how society should balance participant interests against the goals of research. Recommendations are offered to cancer researchers and policymakers going forward to enable ethically appropriate regulation of biospecimen research across its diverse spectrum.

Refinement, Reduction, and Replacement (3R) Strategies in Preclinical Testing of Medical Devices.

The U.S. Food and Drug Administration Center for Devices and Radiological Health (FDA/CDRH) has recently published several in vivo test guidance documents that mention refinements, reductions, or replacement animal testing strategies to facilitate the leveraging of data from large animal safety tests for conventional rodent testing. In response to the recently enacted Food and Drug Administration Safety and Innovation Act Section 907, which facilitates expedited access to novel therapies commonly described as Breakthrough Therapy Designation, FDA/CDRH has discussed efficient regulatory strategies for first-in-human investigation, including early feasibility study guidance. Large gains in humane care and translational research could also be attained by examples in FDA's Guidance for the Use of International Organization for Standardization 10993-1, which states that large animal safety studies may be considered as replacement rodent tests if the scientific principles, methods, and end points (SPME) are considered and applied. This article discusses SPME for the replacement of conventional rodent testing by the inclusion and integration of clinical, diagnostic, and pathologic data obtained from well-designed large animal studies. The recommendations include consideration for study designs that utilize methods for an overall more comprehensive interrogation of animal systems.

Surviving in the Valley of Death: Opportunities and Challenges in Translating Academic Drug Discoveries.

With pharmaceutical companies shrinking their research departments and exiting out of efforts related to unprofitable diseases, society has become increasingly dependent on academic institutions to perform drug discovery and early-stage translational research. Academic drug discovery and translational research programs assist in shepherding promising therapeutic opportunities through the so-called valley of death in the hope that a successful new drug will result in saved lives, improved health, economic growth, and financial return. We have interviewed directors of 16 such academic programs in the United States and found that these programs and the projects therein face numerous challenges in reaching the clinic, including limited funding, lack of know-how, and lack of a regional drug development ecosystem. If these issues can be addressed through novel industry partnerships, the revision of government policies, and expanded programs in translational education, more effective new therapies are more likely to reach patients in need.

Proceedings of the signature series symposium "cellular therapies for orthopaedics and musculoskeletal disease proven and unproven therapies-promise, facts and fantasy," international society for cellular therapies, montreal, canada, may 2, 2018.

The Signature Series Symposium "Cellular Therapies for Orthopaedics and Musculoskeletal Disease Proven and Unproven Therapies-Promise, Facts and Fantasy" was held as a pre-meeting of the 26th International Society for Cellular Therapy (ISCT) annual congress in Montreal, Canada, May 2, 2018. This was the first ISCT program that was entirely dedicated to the advancement of cell-based therapies for musculoskeletal diseases. Cellular therapies in musculoskeletal medicine are a source of great promise and opportunity. They are also the source of public controversy, confusion and misinformation. Patients, clinicians, scientists, industry and government share a commitment to clear communication and responsible development of the field. Therefore, this symposium convened thought leaders from around the world in a forum designed to catalyze communication and collaboration to bring the greatest possible innovation and value to patients with musculoskeletal conditions.

Mind the Gap: From Tool to Knowledge Base.

With the ethical, legal, and societal issues (ELSI) Knowledge Base, we introduce a key element of the Biobanking and Biomolecular Resources Research Infrastructure-European Research Infrastructure Consortium (BBMRI-ERIC) Common Service ELSI, which provides ethical, legal, and societal support for researchers and biobankers involved in transnational research. In contrast to the customized support provided by the ELSI Helpdesk, the ELSI Knowledge Base will be available to the user on a self-serve basis. The information that is made available through a knowledge base comes from multiple sources, usually from several expert contributors who are well versed in the subject matter. The knowledge base provides users with a first orientation on the subject matter, as well as allowing them to explore more detailed information if desired in a self-service manner. It is crucial that the information and knowledge provided are shared in a manner that is user friendly. Long lists of links, legalistic language, and multiple links have to be avoided wherever possible. The long-term sustainability and accuracy of a knowledge base need to be ensured by placing its expert curation and technical maintenance under the responsibility of an organization rather than a research consortium. In its core, it builds on a scenario-based approach using a nonlegalistic language. In addition, the knowledge base connects to frequently asked questions, promotes contract and informed consent templates, how-to-guides, best-practice models, and scripts. The ELSI Knowledge Base is a key element of the BBMRI-ERIC Common Service ELSI, which currently serves biobanks but will be enlarged to serve the biological and medical sciences community. In contrast to the ELSI Helpdesk, which provides customized support, the ELSI Knowledge Base is available to the user on a self-serve basis. The conceptualization of the ELSI Knowledge Base builds on assessments of several ethical, legal, and societal guidance tools that favor a single sustainable knowledge base for closing the knowledge gap by providing practical hands-on guidance for researchers. Ultimately, the ELSI Knowledge Base aims at promoting practical know-how and skills for conducting responsible research.

A European regulatory perspective on cystic fibrosis: current treatments, trends in drug development and translational challenges for CFTR modulators.

In this article we analyse the current authorised treatments and trends in early drug development for cystic fibrosis (CF) in the European Union for the time period 2000-2016. The analysis indicates a significant improvement in the innovation and development of new potential medicines for CF, shifting from products that act on the symptoms of the disease towards new therapies targeting the cause of CF. However, within these new innovative medicines, results for CF transmembrane conductance regulator (CFTR) modulators indicate that one major challenge for turning a CF concept product into an actual medicine for the benefit of patients resides in the fact that, although pre-clinical models have shown good predictability for certain mutations, a good correlation to clinical end-points or biomarkers (e.g. forced expiratory volume in 1 s and sweat chloride) for all mutations has not yet been achieved. In this respect, the use of alternative end-points and innovative nonclinical models could be helpful for the understanding of those translational discrepancies. Collaborative endeavours to promote further research and development in these areas as well as early dialogue with the regulatory bodies available at the European competent authorities are recommended.

Clinical translation and regulatory aspects of CAR/TCR-based adoptive cell therapies-the German Cancer Consortium approach.

Adoptive transfer of T cells genetically modified by TCRs or CARs represents a highly attractive novel therapeutic strategy to treat malignant diseases. Various approaches for the development of such gene therapy medicinal products (GTMPs) have been initiated by scientists in recent years. To date, however, the number of clinical trials commenced in Germany and Europe is still low. Several hurdles may contribute to the delay in clinical translation of these therapeutic innovations including the significant complexity of manufacture and non-clinical testing of these novel medicinal products, the limited knowledge about the intricate regulatory requirements of the academic developers as well as limitations of funds for clinical testing. A suitable good manufacturing practice (GMP) environment is a key prerequisite and platform for the development, validation, and manufacture of such cell-based therapies, but may also represent a bottleneck for clinical translation. The German Cancer Consortium (DKTK) and the Paul-Ehrlich-Institut (PEI) have initiated joint efforts of researchers and regulators to facilitate and advance early phase, academia-driven clinical trials. Starting with a workshop held in 2016, stakeholders from academia and regulatory authorities in Germany have entered into continuing discussions on a diversity of scientific, manufacturing, and regulatory aspects, as well as the benefits and risks of clinical application of CAR/TCR-based cell therapies. This review summarizes the current state of discussions of this cooperative approach providing a basis for further policy-making and suitable modification of processes.
