ECLIM-SEHOP, a new platform to set up and develop international academic clinical trials for childhood cancer and blood disorders in Spain
Cancer and blood disorders in children are rare. The progressive improvement in survival over the last decades largely relies on the development of international academic clinical trials that gather the sufficient number of patients globally to elaborate solid conclusions and drive changes in clinical practice. The participation of Spain into large international academic trials has traditionally lagged behind of other European countries, mainly due to the burden of administrative tasks to open new studies, lack of financial support and limited research infrastructure in our hospitals.
The objective of ECLIM-SEHOP platform (Ensayos Clínicos Internacionales Multicéntricos-SEHOP) is to overcome these difficulties and position Spain among the European countries leading the advances in cancer and blood disorders, facilitate the access of our patients to novel diagnostic and therapeutic approaches and, most importantly, continue to improve survival and reducing long-term sequelae. ECLIM-SEHOP provides to the Spanish clinical investigators with the necessary infrastructural support to open and implement academic clinical trials and registries.
In less than 3 years from its inception, the platform has provided support to 20 clinical trials and 8 observational studies, including 8 trials and 4 observational studies where the platform performs all trial-related tasks (integral support: trial setup, monitoring, etc.) with more than 150 patients recruited since 2017 to these studies. In this manuscript, we provide baseline metrics for academic clinical trial performance that permit future comparisons.
ECLIM-SEHOP facilitates Spanish children and adolescents diagnosed with cancer and blood disorders to access state-of-the-art diagnostic and therapeutic strategies.
KeywordsPediatric hematology and oncology Clinical trials Drug development Clinical research
In Spain, a new case of cancer is diagnosed annually for every 6500 children under 15 years of age. This represents 1100 new cases between 0 and 14 years and 450 between 15 and 19 , only a small fraction of the nearly quarter of million new invasive cancer diagnosed in our country every year for the whole population if we include adults and the elderly . Cancer represents the first cause of death due to disease in children. Nonetheless, survival has considerably improved within the past 30 years and current overall survival in Spain is 80% at 5 years . These survival figures are still lower than data available for other countries of Western Europe such as Germany or France (> 85% at 5 years) . Despite important reductions in mortality, childhood cancer survivors still face an unacceptable burden of long-term toxicities and sequelae .
Role of the Spanish Society of Pediatric Hematology and Oncology (SEHOP)
In Spain, the Registro Español de Tumores Infantiles (RETI) was created in 1979, a milestone in Spanish pediatric oncology that has collected data on more than 26,000 patients . In 2008, the Sociedad Española de Oncología Pediátrica (SEOP) and the Sociedad Española de Hematología Pediátrica (SEHP) merged into SEHOP bringing together 250 members (mainly pediatricians, hematologists, pediatric surgeons and radiotherapists) from more than 40 centers distributed throughout the national geography. The aim of SEHOP (http://www.sehop.org) is, on one hand, to promote the development of pediatric hematology and oncology in Spain in its facets of prevention, best medical care, training, teaching and research; and, on the other hand, to ensure the right that every child and adolescent have to be assisted in institutions that have the necessary means and sufficiently qualified health personnel using therapeutic schemes that are nationally or internationally recognized .
Role of clinical trials in pediatric oncology
International collaboration and collaborative clinical trials are the main factors contributing to the major improvements in survival for many childhood cancers [7, 8, 9]. For children and adolescents with cancer, participation in international clinical trials has become the standard of care, improving and ensuring the quality of the treatment received, as well as greatly increasing the scientific value of the work at a global level . As stated in the document European Standards of Care for Children with Cancer : “All children with cancer should be treated according to the best available treatment protocols. There is general agreement that this is best provided within units that are active in clinical research and cancer registration processes. When available, children should be offered the opportunity to participate in relevant clinical trials that aim to improve the optimal treatment for all children”.
Pediatric international clinical trials in Spain: current situation
The transition from individual Spanish institutional efforts to open large international trials, to a central Spanish pediatric infrastructure for implementing and developing international clinical trials, first created in 2014 and named ARCAHI (Armonización en el tratamiento del cáncer infantil y las hemopatías en España), and from 2017 further developed into the ECLIM-SEHOP platform (Ensayos Clínicos Internacionales Multicéntricos-SEHOP).
The progressive incorporation of five large pediatric Spanish centers from 2010 onwards into the Innovative Therapies for Children with Cancer Consortium (ITTC) (http://www.itcc-consortium.org), a European network focused on early phase clinical trials of new drugs whose aim is to develop novel therapies for the treatment of pediatric and adolescent cancers in cooperation with regulatory bodies, pharmaceutical companies, parents and patients.
The close collaboration between SEHOP and other Spanish cancer research collaborative groups, such as the Grupo Español de Investigación en Sarcomas (GEIS, http://www.grupogeis.org), that has opened the door to pediatric cancer units to adhere to large international trials that might not been possible otherwise (e.g., Euroewing 2012, IS-GEIS-OS-02).
The changes in 2007 in the European legislation favoring the development of new anticancer agents in children by means of the pediatric investigational plan (PIP) requisite for pharmaceutical companies  and the implementation in Spain in 2015 of the updated clinical trial regulation (Real Decreto 1090/2015, 4th December)  that facilitates the administrative burden and reduces the costs for opening new academic studies, among other changes;
The increasing active partnership of the SEHOP working groups with International Collaborative Groups trial such as SIOPEN, Euronet, SIOP-BTG, SIOPEL, I-BFM, EICNHL or the Histiocyte Society and the leadership of Spanish investigators in European networks [e.g., the LINES trial (NCT01728155) in neuroblastoma being the first international trial in pediatric oncology sponsored by a Spanish institution (IIS La Fe, Valencia)].
The objective of this manuscript is to report the setup of the new collaborative platform ECLIM-SEHOP, as well as establishing baseline metrics for academic clinical trial performance that permits future comparisons.

Setup of ECLIM-SEHOP
Following on the initial work of the ARCAHI initiative and the clinical trials office of SEHOP, the ECLIM-SEHOP platform was started in 2017 and fully established from 2018 onwards. The initial setup phase comprised the establishment of the platform organigram, development of SOPs for defining the evaluation and selection criteria for the studies to support and defining the roles of the members of the platform (Supplementary Document 1), and lastly the review and approval of the structure and SOPs by the SEHOP Executive Board. To have the capacity and expertise to perform all trial-related tasks required by international sponsors, an agreement with a contract research organization (CRO) experienced in the conduct of academic clinical trials was sought (http://www.sofpromed.com).
Objectives of ECLIM-SEHOP
To establish the infrastructure to allow the participation of Spain into international academic collaborative clinical trials.
To increase the number of academic international clinical trials open in Spain.
To improve the setup (timelines) and conduct (quality control) of academic and international clinical trials open in Spain.

Clinical trials are used to determine the most effective and safe treatments for a given disease. In childhood cancer, each trial aims at improving survival, reducing side effects or long-term sequelae of treatment. In some countries of Western Europe, participation in clinical trials has become the standard of care in children and adolescents with cancer.
To date, infrastructure and support to facilitate participation in academic international multicenter collaborative clinical trials in pediatric cancer in Spain has not matched the same standards than other European countries such as France, Germany or the United Kingdom. Initiatives like SCReN (Spanish Clinical Research Network, http://www.scren.es) provide excellent support to some clinical trials, but so far, have had limited resources and could not cover all the needs from the pediatric oncology community.
Historically, Spain has not been able to participate in multiple international clinical trials because of the above-mentioned lack of resources and infrastructure to adapt to modern regulatory standards and provide good quality data. For some other studies, the time to setup the trials in our country has been so long due to administrative barriers that the trials were completed or nearly completed internationally by the time the trials were open.
The participation of our country in international clinical trials makes a huge contribution to our society for several reasons: (1) clinical trials evaluate more novel strategies and offer access to new treatments, (2) treatment within clinical trials is always done in centers with proven experience, with less variability and greater control of toxicities that may appear, being safer than being treated outside trials, (3) clinical trials allow to advance scientific knowledge and improve results of childhood cancer therapy and (4) collaboration at national and international level is essential to improve the results in such a significant group of rare diseases.
In our country, survival of childhood cancer has improved significantly in recent years, but the data are still below that of other neighboring countries in Western Europe such as France, the United Kingdom or Italy. For example, in the case of lymphoblastic leukemia, the EUROCARE5 study and a national study of the Registro Nacional de Tumores Infantiles (RETI-SEHOP) have reported lower survival rates in Spain (83%) compared to France (90%), Germany (90%), Italy (89%) or United Kingdom (88%) [4, 18].
With the implementation of the first European Clinical Trial Directive in 2001, the development and conduct of academic clinical trials entailed a significant burden of administrative duties at the international, national and local levels. These tasks surely exceed the capacity of individual clinical investigators in charge of each study as national coordinators. It was, therefore, necessary to provide support for all the new international clinical trials that are being implemented and maintain a stable and organized infrastructure to carry out these activities.
Since 2004, there has been a progressive improvement in our performance metrics as a country in clinical trial setup and conduct . This positive change is due, among other factors, to changes in current legislation, learning curve of participating institutions and ethics committees.
Most of the activity in oncology clinical trials carried out in Spain is dependent on the pharmaceutical industry, which is surely more focused on new drug development, rather than on standard clinical practice, procedures such as transplant or surgery, radiotherapy or medical devices, and does not necessarily respond to the capabilities and opportunities of the clinical and academic research ecosystem, nor to the epidemiological reality of cancer in our country . In Spain, 76% of this activity is industry sponsored, compared to that of 49% in France, 56% in the Netherlands, 62% in Italy or 65% in the United Kingdom. To improve our capacity to innovate in the field of clinical research, and achieve the goal that every child and adolescent in our country can potentially be included in a clinical trial, it is necessary for the Spanish public institutions to have greater funding and capabilities to develop more academic trials and implement collaborative international plans. ECLIM-SEHOP is supported with funds from competitive grants from the Asociación Española Contra el Cancer (AECC) and Fundación Inocente as well as other non-competitive contributions from non-profit organizations, mainly Federación Española de Padres de Niños con Cáncer, Asociación Pablo Ugarte y Fundación Mar, and, therefore, in constant need of identifying financial resources to make it sustainable. Still, our clinical trial setup metrics can be improved by far. Hopefully, the data provided here will serve as a baseline for future comparisons and, with time, the timelines to open clinical trial will shorten, so that these new advances reach our patients as soon as possible.
In summary, thanks to the enormous work and generosity of SEHOP members that are leading on these clinical trials and all stakeholders involved in this process, including parents, patients and other healthcare professionals, together with the help of the ECLIM-SEHOP platform we will facilitate Spanish children and adolescents diagnosed with cancer and blood disorders to access state-of-the-art diagnostic and therapeutic strategies, and in this way continue to improve survival rates and decreasing the side effects of long-term treatment.
We would like to thank all children and parents who participate in clinical trials and the clinical staff, research nurses, and research assistants of the different institutions. We thank the members of the technical secretariat of the Sociedad Española de Hematología y Oncología Pediátrica (SEHOP) and Fundación SEHOP, particularly Inmaculada Toledano and Falastin Eljishi for their continued work, support and enthusiasm. We thank Patricio Ledesma, Head of Clinical Operations as well as all the staff at Sofpromed Investigación Clínica, for the close and fruitful collaboration in building up ECLIM-SEHOP. We are grateful to our colleagues of SEHOP and their teams (physicians, nurses, study coordinators, etc.) for their interest and commitment on clinical research to improve care for children with cancer and hematological diseases. We would specially like to thank Dr. Tomás Acha who, during his term as president of SEHOP, was the first to propose that a platform to support Spanish physicians and investigators was necessary to foster clinical research in pediatric cancer and blood disorders so that Spanish children had the same treatment opportunities as their peers in other European countries; he set up the foundations for the current ECLIM-SEHOP platform to be developed, together with the help of the SEHOP Executive Committee.
