Resumen del contexto y de los objetivos generales del proyecto

Cancer is one of the main causes of death within Europe. Given the aging of the population it can be expected that the number of Europeans suffering cancer will increase in the coming years. It is therefore important to develop and optimize anti-cancer therapies. Recently, immunotherapy against cancer, based on using a patient’s own immune system to eradicate cancers, was introduced into the clinic. This approach has provided a qualitative change in the treatment of various cancers, leading to long term survival of patients whose life expectancy with more traditional therapies (radio- and chemotherapy) was much more limited. This therapy is still at its very early stages of development and needs to be optimized to reduce side effects and be expanded to more types of tumors. Europe is lagging as compared to the USA and China in the development of these therapeutic approaches, thereby missing out on important clinical and economic opportunities. The EN-ACTI2NG network (European Network on Anti-Cancer ImmunoTherapy Improvement by Modification of CAR and TCR Interactions and Nanoscale Geometry) trains 10 early stage researchers (ESRs) in the development of immunotherapy approaches centered on genetic modification of the patient’s white blood cells with receptors that can recognize the tumors. Scientific projects are aimed at 1) understanding the molecular mechanisms underlying the function of these receptors, in order to develop more rational ways of designing such receptors, 2) optimizing function by defining new formats and altering interaction modes of these receptors and 3) to isolate receptors recognizing new targets on the tumor cells, thereby expanding the clinical reach of this therapy. Via additional training in research techniques, career planning and communication skills and by performing secondments with research groups and companies that have complementary approaches the early stage researchers should receive a multidisciplinary education that should allow them to embark on a successful professional career in development or implementation of immunotherapy.

The scientific achievements at the end of this project include the development of new formats of cancer-specific immune receptors that have shown improved response to tumors in pre-clinical models of cancer immunotherapy, isolation and characterization of new immune receptors specific for certain types of leukemia, and new tools and findings that help us understand how these cancer-specific immune receptors work. The 10 ESRs have completed their scientific and complementary training program and will prepare and defend their PhD dissertation over the course of the next two years, providing them with a solid education and preparedness to further academic, industrial or regulatory careers in cancer immunotherapy or related research areas. As a matter of fact, the first ESR to graduate this spring will join a recently founded cancer immunotherapy company to head a R&D laboratory on CAR-T cell development.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

The outcome of the research performed under the EN-ACTI2NG program includes the development of new techniques and devices that allow very detailed and efficient analysis of the mechanisms underlying tumor-specific antigen receptor signaling, generation of new tumor-specific receptors that will be tested in the clinic and various approaches that improve cellular anti-tumor therapy: generation of immune cells that rely on the activity of two different receptors to attack the tumor, thereby enhancing the specificity of these cells for tumor cells; co-receptors that can enhance the usually weak anti-tumor responses of immune cells; inclusion of new signaling domains in tumor-specific recombinant receptors that have shown promise in preclinical models of cancer immunotherapy; and a completely new class of RNA based co-stimulators that can enhance weak immune cell responses and that have been successfully tested in pre-clinical models of infection and anti-tumor responses.

Ten articles describing this research have been published in peer-reviewed journals at the closing date of this project and more manuscripts are under review or are being prepared for submission. Three patent applications have been filed and licensing agreements have been reached that should facilitate the further development of these findings into applications that improve treatment and outcome for patients. Findings of the EN-ACTI2NG network and other groups in the field of cancer immunology have been shared via Twitter (@enacti2ng) and Facebook (The EN-ACTI2NG Initial Training Network), students have shared their experience as young researchers via blogs and podcasts and interviews (see http://www.enacti2ng-itn.eu/ and our social media channels) and an animation video explaining cellular cancer immunotherapy and the role of the EN-ACTI2NG network in the development of this important clinical approach has been made (https://www.youtube.com/watch?v=zo8LCn79QQc).

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

The actions developed under the EN-ACTI2NG project have provided various unique approaches to improving the cellular antitumor response, not only working on new designs of current tumor-specific immune receptors but also introducing completely new ways of boosting these responses with additional receptors and pharmacological agents. The already established procedures and infrastructure to move cancer-specific immune receptors to clinical trials and the clinic allow that these improvements and innovations could make it to their therapeutic application within a relatively short time frame. The licensing of a patent on a new leukemia-specific receptor isolated during the course of this action is a clear example of the relevance of our findings and the socio-economic impact it will likely have. Finally, EN-ACTI2NG educated a group of smart, ambitious and enthusiastic researchers coming from 10 different countries with knowledge and skills that can in their further career strongly contribute to the development and implementation of new clinical approaches to cancer in academia, clinics and companies in Europe and the world.
