Precision Medicine in Non-Communicable Diseases.

The increase in life expectancy during the 20th century ranks as one of society's greatest achievements, with massive growth in the numbers and proportion of the elderly, virtually occurring in every country of the world. The burden of chronic diseases is one of the main consequences of this phenomenon, severely hampering the quality of life of elderly people and challenging the efficiency and sustainability of healthcare systems. Non-communicable diseases (NCDs) are considered a global emergency responsible for over 70% of deaths worldwide. NCDs are also the basis for complex and multifactorial diseases such as hypertension, diabetes, and obesity. The epidemics of NCDs are a consequence of a complex interaction between health, economic growth, and development. This interaction includes the individual genome, the microbiome, the metabolome, the immune status, and environmental factors such as nutritional and chemical exposure. To counteract NCDs, it is therefore essential to develop an innovative, personalized, preventative, early care model through the integration of different molecular profiles of individuals to identify both the critical biomarkers of NCD susceptibility and to discover novel therapeutic targets.

Time for Change? The Why, What and How of Promoting Innovation to Tackle Rare Diseases - Is It Time to Update the EU's Orphan Regulation? And if so, What Should be Changed?

Since developments are global in the healthcare arena, more should be done to align EU and other big markets' regulatory practices for rare disease patients. Notwithstanding efforts and cooperation between the US and EU aimed to harmonize their strategic plans in the field of orphan drugs, regulatory criteria and procedures to gain the designation, terms and classifications should be still harmonised. Aligning the criteria of prevalence and support to orphan medicines in the various jurisdictions internationally, would facilitate patient recruitment eventually at global level, so as to gain the data and the biological insights required to identify biomarkers and appropriate endpoints needed for progressing clinical development. A conducive regulatory environment can further support the development of medicines to treat rare diseases. Overall there is a need for joined-up regulatory process coordination. Better integration of regulatory pathways and better integration of regulatory systems, such as scientific tools and methods to generate evidence, would be helpful. There is a need to revise and agree the current frameworks to be improved which will take into account the considerations and challenges to diagnose and treat different rare diseases and improve quality of life. Deliberative processes with multi-stakeholders' involvement for reimbursement should be considered. This paper explores the successes and limitation of both the regulation and its implementation mechanisms in the current regulatory context, and suggests some improvements that could maximise its benefits and boost rare disease research even further.

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.

Nanomedicines in the EU-Regulatory Overview.

This article provides an overview of the European Union (EU) framework for the marketing authorisation of medicinal products, at both European and National level, and aims to demonstrate the current position and experience with nanomedicines. It will be described how the EU promotes the development of new nanomedicines by publishing guidance, providing scientific advice and engaging with multiple regions for the convergence of scientific requirements to support the quality, safety and efficacy of nanomedicines. It will also be highlighted the regulatory challenges deriving from the use of an innovative technology that crosses different platforms and the importance of overcoming challenges for the benefit of public health.

Changes and determination of dosing recommendations for medicinal products recently authorised in the European Union.

INTRODUCTION: The quantity and quality of data for determining the dose and treatment schedule of medicinal products is directly related to how safe and efficacious these medicines are and how successful they can be used to treat patients. AREAS COVERED: This review provides an analysis of dose-related label modifications of recently approved drugs. It shows which areas could benefit from a better dose-exposure-response understanding, both during initial assessment and after marketing authorisation. This analysis highlights regulators' considerations in dosage evaluations and provides reflections for drug developers on how to ensure best possible dose selection in the interest of the patients. EXPERT OPINION: Using modelling and simulation, pharmacogenomics, population pharmacokinetics, physiologically based pharmacokinetic models and drug-drug interaction studies in conjunction with well-designed clinical trials will improve the understanding of the pharmacology of medicines, of the physiology of the disease and of the dose-exposure-response relationship during drug development. More focus should be given to the investigation of dose and regimens for special populations before applying for marketing authorisation. Consequently, regulators could review dose-exposure-response data with more certainty and better define dose recommendations in the label.

White spots in pharmaceutical pipelines-EMA identifies potential areas of unmet medical needs.

Unmet medical needs are a priority for organizations such as the WHO and major public-private initiatives, such as Innovative Medicines Initiative, were established to speed up the development of better and safer medicines for patients. To assist such projects, the EMA in its 'Road Map to 2015' considered the mapping of unmet medical needs as a priority. This study has identified medical conditions for which the EMA could not identify developments in the pharmaceutical pipelines, that is, 'white spots'. Our analysis was made using external data sources as well as mining data of the EMA. The main areas for white spots were oncology, infectious diseases and certain psychiatric conditions. According to our data and a review of literature, in a number of these white spots, diagnostic tools may even be missing. The identification of those conditions will benefit stakeholders, including regulators, research funding bodies and patients' organizations.

European Medicines Agency initiatives and perspectives on pharmacogenomics.

Pharmacogenomics, the study of variations of DNA and RNA characteristics as related to drug response, has become an integral part of drug development and pharmacovigilance, as reflected by the incorporation of pharmacogenomic data in EU product information. In this short review article, we describe recent European Medicines Agency initiatives intended to support further the implementation of pharmacogenomics in drug development and surveillance so that patients and the public can benefit from advances in genomic science and technology.

Pharmacogenetics in the evaluation of new drugs: a multiregional regulatory perspective.

Pharmacogenetics, one of the cornerstones of personalized medicine, has the potential to change the way in which health care is offered by stratifying patients into various pretreatment categories, such as likely responders, likely non-responders or likely to experience adverse drug reactions. In order to advance drug development and regulatory science, regulatory agencies globally have promulgated guidelines on pharmacogenetics for nearly a decade. The aim of this article is to provide an overview of new guidelines for the implementation of pharmacogenetics in drug development from a multiregional regulatory perspective - encompassing Europe, the United States and Japan - with an emphasis on clinical pharmacokinetics.

Renal biomarker qualification submission: a dialog between the FDA-EMEA and Predictive Safety Testing Consortium.

The first formal qualification of safety biomarkers for regulatory decision making marks a milestone in the application of biomarkers to drug development. Following submission of drug toxicity studies and analyses of biomarker performance to the Food and Drug Administration (FDA) and European Medicines Agency (EMEA) by the Predictive Safety Testing Consortium's (PSTC) Nephrotoxicity Working Group, seven renal safety biomarkers have been qualified for limited use in nonclinical and clinical drug development to help guide safety assessments. This was a pilot process, and the experience gained will both facilitate better understanding of how the qualification process will probably evolve and clarify the minimal requirements necessary to evaluate the performance of biomarkers of organ injury within specific contexts.

Clinical trials for registration in the European Union: the EMEA 5-year experience in oncology.

The evaluation of quality, safety and efficacy of medicinal products by regulatory agencies is a necessary step for obtaining marketing authorisation in the European Union (EU). The objective of this paper is to outline some key aspects of the EU regulatory system relevant to the field of oncology. Regulatory standards in oncology and the experience with anti-neoplastic and endocrine therapy agents in the centralised EU review system are presented. Also, the most common pitfalls encountered with oncology applications that were rejected are illustrated. The review is based on the first 5 years (1995-1999) of operation of the European Agency for the Evaluation of Medicinal Products (EMEA). Nineteen out of 30 different oncology drugs submitted during this period were approved, based on the recommendations of the Committee for Proprietary Medicinal Products (CPMP), which is the main scientific body within the EMEA responsible for evaluating medicines for human use. Although, in general, randomised trials to test the benefit of the new drug are a prerequisite for approval, this series showed that in strictly defined situations, approval could be obtained based on non-randomised trials measuring surrogate endpoints, provided the applicant agreed to the completion of a further programme of studies. These situations were the majority in our series and the CPMP has produced a guideline in oncology to address these specific requirements. Eleven out of the 30 oncology applications did not establish a positive benefit/risk profile of the drug in the proposed therapeutic indication, and were therefore rejected. Failure generally occurred because applications were based on too small series of patients or relied on the results of exploratory analyses after pre-defined analyses had failed to produce the expected results or, particularly for diagnostic agents, due to the fact that the effect of the agent had been measured only in terms of endpoints that were of unclear relevance.
