Clinical Development and Commercialization of Advanced Therapy Medicinal Products in the European Union: How Are the Product Pipeline and Regulatory Framework Evolving?

The research and development of advanced therapy medicinal products (ATMPs) has been active in Europe and worldwide during recent years. Yet, the number of licensed products remains low. The main expected legal change in the near future in the European Union (EU) concerns the regulation on clinical trials (536/2014), which will come into force in 2018. With this new framework, a more harmonized and swift process for approval of clinical trials is anticipated, which is expected to support the entry of new innovations into the EU market. A survey on ATMPs in clinical trials during 2010-2015 in the EU was conducted in order to study the trends of ATMP development since the earlier survey published in 2012. According to the results, the number of clinical trials using ATMPs is slowly increasing in the EU. Yet, the focus is still in early development, and the projects are mainly carried out by small and medium-sized enterprises, academia, and hospitals. Oncology is the main area of clinical development. Yet, the balance between cell-based products and gene therapy medicinal products in this area may be changing in the future due to the new T-cell technologies. Many limitations and challenges are identified for ATMP development, requiring proportionate regulatory requirements. On the other hand, for such a novel field, the developers should be active in considering possible constraints and actively engage with authorities to look for solutions. This article provides up to-date information on forthcoming regulatory improvements and discusses the main challenges hampering the commercialization of ATMPs in the EU.

The Quality of Rare Disease Registries: Evaluation and Characterization.

BACKGROUND: The focus on the quality of the procedures for data collection, storing, and analysis in the definition and implementation of a rare disease registry (RDR) is the basis for developing a valid and long-term sustainable tool. The aim of this study was to provide useful information for characterizing a quality profile for RDRs using an analytical approach applied to RDRs participating in the European Platform for Rare Disease Registries 2011-2014 (EPIRARE) survey. METHODS: An indicator of quality was defined by choosing a small set of quality-related variables derived from the survey. The random forest method was used to identify the variables best defining a quality profile for RDRs. Fisher's exact test was employed to assess the association with the indicator of quality, and the Cochran-Armitage test was used to check the presence of a linear trend along different levels of quality. RESULTS: The set of variables found to characterize high-quality RDRs focused on ethical and legal issues, governance, communication of activities and results, established procedures to regulate access to data and security, and established plans to ensure long-term sustainability. CONCLUSIONS: The quality of RDRs is usually associated with a good oversight and governance mechanism and with durable funding. The results suggest that RDRs would benefit from support in management, information technology, epidemiology, and statistics.

Rare disease registries classification and characterization: a data mining approach.

BACKGROUND: The European Commission and Patients Organizations identify rare disease registries (RDRs) as strategic instruments to develop research and improve knowledge in the field of rare diseases. Interoperability between RDRs is needed for research activities, validation of therapeutic treatments, and public health actions. Sharing and comparing information requires a uniform and standardized way of data collection, so levels of interconnection between RDRs with similar aims and/or nature of data should be identified. The objective of this study is to define a classification and characterization of RDRs in order to identify different profiles and informative needs. METHODS: Exploratory statistical analyses (cluster analysis and random forest) were applied to data derived from the EPIRARE project ('Building Consensus and Synergies for the EU Rare Disease Patient Registration') survey on the activities and needs of RDRs. RESULTS: The cluster analysis identified 3 main typologies of RDRs: public health, clinical and genetic research, and treatment registries. The analysis of the most informative variables, identified by the random forest method, led to the characterization of 3 types of RDRs and the definition of different profiles and informative needs. CONCLUSIONS: These results represent a useful source of information to facilitate the harmonization and interconnection of RDRs in accordance with the different profiles identified. It could help sharing the information between RDRs with similar profiles and, whenever possible, interconnections between registries with different profiles.

Resveratrol: Antioxidant activity and induction of fetal hemoglobin in erythroid cells from normal donors and ß-thalassemia patients.

Thalassemia and sickle-cell anemia (SCA) present a major public health problem in countries where the number of carriers and affected individuals is high. As a result of the abnormalities in hemoglobin production, cells of thalassemia and SCA patients exhibit oxidative stress, which ultimately is responsible for the chronic anemia observed. Therefore, identification of compounds exhibiting both antioxidant and hemoglobin-inducing activities is highly needed. Our results demonstrate resveratrol to be such a compound. This was shown both in the human K562 cell line, as well as in erythroid precursors derived from normal donors and ß-thalassemia patients. Resveratrol was shown to exhibit antioxidant activity and to stimulate the expression of the γ-globin genes and the accumulation of fetal hemoglobin (HbF). To the best of our knowledge, this is the first report pointing to such a double effect of resveratrol. Since this natural product is already marketed as an antioxidant, future investigations should concentrate on demonstrating its potential to augment HbF production in experimental animal models (e.g., thalassemia and SCA mice) as well as in patients. We believe that the potential of clinical use of resveratrol as an antioxidant and HbF stimulator may offer a simple and inexpensive treatment to patients.
