Meyer-Lindenberg A, Leweke FM. EU - Europäische Union 241909: EU-GEI: European Network of National Schizophrenia Networks Studying Gene-Environment Interactions. 05/2010-04/2015.

The aim of EU-GEI is to identify, over a 5-year period, the interactive genetic, clinical and environmental determinants involved in the development, severity and outcome of schizophrenia. In order to identify these interactive determinants, EU-GEI will employ family-based, multidisciplinary research paradigms, which allow for the efficient assessment of gene-environment interactions. In order to go beyond old findings from historical convenience cohorts with crude measures of environmental factors and clinical outcomes, the focus in EU-GEI will be on recruitment of new, family-based clinical samples with state-of-the-art assessments of environmental, clinical and genetic determinants as well as their underlying neural and behavioural mechanisms. New statistical tools will be developed to combine the latest multilevel epidemiological with the latest genome-wide genetic approaches to analysis. Translation of results to clinical practice will be facilitated by additional experimental research and risk assessment bioinformatics approaches. This will result in (i) the identification of modifiable biological and cognitive mechanisms underlying gene-environment interactions and (ii) the construction of Risk Assessment Charts and Momentary Assessment Technology tools which can be used for (i) early prediction of transition to psychotic disorder in helpseeking individuals with an at-risk mental state and (ii) early prediction of course and outcome after illness onset. In order to reach these goals, EU-GEI has assembled a multidisciplinary team of top schizophrenia researchers who have the range of aim of EU-GEI is to identify, over a 5-year period, the interactive genetic, clinical and environmental determinants involved in the development, severity and outcome of schizophrenia.

Meyer-Lindenberg A, Rietschel M. DFG - Deutsche Forschungsgemeinschaft SFB 636: TP B07: Plastizität präfrontaler Netzwerke beim Menschen: Genetische Variation, zelluläre Mechanismen und Modulation durch Neurofeedback. 01/2012-12/2015.

Das Arbeitsprogramm beinhaltet drei Experimente an gesunden Kontrollprobanden, die mit der in der gegenwärtigen Förderperiode entwickelten Methode durch repetitive transkranielle Magnetstimulation und multimodale Bildgebung in Hinblick auf ihre präfrontale Plastizität und Konnektivität charakterisiert werden. Im ersten Experiment werden die Auswirkungen genomweit signifikanter Risikogenvarianten auf die präfrontale Plastizität und Konnektivität untersucht, indem mit Methoden der „Imaging genetics“ die Assoziation dieser Genotypen mit den multimodalen Bildgebungsdaten in der Gesamtgruppe untersucht werden. Im zweiten Experiment werden neuronal-synaptische Marker der Plastizität bestimmt und mit den Bildgebungsdaten in Beziehung gesetzt. Dazu werden aus Hautbiopsien induzierte pluripotente Stammzellen gewonnen, neuronal differenziert und charakterisiert, und mit Bildgebungsparametern der Plastizität korreliert. Im dritten Experiment wird die Frage untersucht, ob die in der gegenwärtigen Förderperiode identifizierten neuronalen Interaktionen durch Neurofeedback veränderbar sind. Dazu wird ein zusätzliches Konnektivitäts-Echtzeit-funktionell-magnetresonanztomographisches Experiment durchgeführt, in denen die Probanden lernen, präfrontal-hippokampale und zingulär-amygdaläre Konnektivität zu modulieren.

Meyer-Lindenberg A. EU - Europäische Union 115008: IMI JU NEWMEDS: Novel Methods Leading to New Medications in Depression and Schizophrenia. 09/2009-08/2014.

Despite remarkable advances in molecular and imaging technologies and nearly 15,000 articles on schizophrenia and depression (S&D) every year, there have been few truly innovative new chemical entities (NCEs) which have made it to the clinic. While there has been a tremendous explosion of new knowledge: dozens of single-nucleotide polymorphisms linked to disease, hundreds of new molecules and pathways identified, numerous imaging findings differentiating patients from controls, yet, it has been hard to take these findings from the bench to the clinic. We think there are three major bottlenecks that are holding the field back: i) a lack of pathophysiologically-accurate animal models guiding the drug discovery of NCEs; ii) a lack of tools and tests in healthy volunteers that can provide early indication of efficacy; and iii) the reliance of clinical trials on symptom-based DSM-categories which inevitably lead to biologically heterogeneous groups of patients. To overcome these limitations, we have brought together a consortium of six leading European and an Israeli academic institution (which bring expertise in animal models, genetics, functional MRI and PET imaging, clinical settings and analysis methods) and two SMEs (which bring expertise in high-throughput genetics, transcriptomics and proteomics) who will partner with the dozen EFPIA partners in the NEWMEDS consortium. To specifically target the challenges identified in Call 10, the NEWMEDS consortium will: a) develop animal models that focus on reliable cross-species endophenotypes (e.g., cognitive function, electrophysiology) and use crossspecies methods (small-animal MRI, EEG and micro-PET) to bring animal models closer to clinical endpoints; b) validate the use of fMRI-based paradigms as early and surrogate markers for efficacy; and to combine this with PET approaches for measuring changes in endogenous transmitters – thus providing new methods that can be implemented in small Phase 1B studies in healthy volunteers to provide guidance for drug development; and c) identify pharmacogenetic biomarkers that can be used to stratify patients within an umbrella DSM-diagnosis, thus allowing for targeted clinical trials, individualized treatment and back-translation of subgroup-specific biomarkers into preclinical drug discovery. To increase the chance of a breakthrough we will implement new analytical approaches – the use of support vector machine learning algorithms for image analyses; the use of Bayesian and growth mixture models for more meaningful analyses of clinical trial data. The project will be delivered through a series of integrated workpackages organized in three clusters – preclinical models, imaging methods, and biomarker development as exemplified in Figure 1. Our consortium has achieved its 1:1 in-kind match, indicative of the involvement and commitment of all EFPIA partners. One of Europe’s leading scientific management SMEs (GABO:mi) will facilitate the management of NEWMEDS and a distinguished international Scientific Advisory Board will provide input and guidance. To ensure that we maximally integrate with other ongoing international initiatives, we have commitments of collaborations from several international consortia and experts (e.g. MATRICS, NIH Biomarkers Consortium). By the end of the 5 year project we expect to provide ready to use new cross-validated animal models, new fMRI methods with dedicated analysis techniques, new PET radioligands, as well as new genetic and proteomic biomarkers for patient-segmentation or individual response prediction. These tools should provide our EFPIA partners with an added competitive advantage in developing new drugs for S&D.

Meyer-Lindenberg A. EU - Europäische Union 115300: EU-AIMS - European Autism Interventions – A Multicentre Study for Developing New Medications. 04/2012-03/2017.

There are no effective pharmacological treatments for the core symptoms of autism spectrum disorder (ASD), and our understanding of the pathophysiology of the disease is poor. Research is hampered by a lack of valid and reliable cellular assays and animal models; an absence of tests that demonstrate efficacy in healthy volunteers from childhood to adulthood; and the reliance of clinical trials on biologically heterogeneous groups of patients as operationally-defined by DSM/ICD10 categories. Further, even if novel treatments were developed, there is no EU platform to test them clinically. Despite these limitations, the recent identification of genetic risk factors for ASD provides unique opportunities to substantially improve this situation. We therefore propose an integrated, translational, effort to achieve key objectives for ASD research, which will deliver new research tools and standards for clinical development, and pave the way for drug discovery and clinical trials. To implement this integrated effort, 13 leading ‘hubs’ in European institutions (with linked ‘satellites’ across the EU) have partnered with Autism Speaks (the world’s leading Autism Research Charity), three SMEs and EFPIA to: a) develop cellular assays and animal models based on confirmed genetic risks, and utilize these models to focus on translational endophenotypes for facilitating new drug discovery; b) validate biomarkers and patient group stratification to optimize conditions for clinical trials; and c) develop a sustainable EU-wide clinical infrastructure to promote research and development of new drugs. We will couple this integrated research effort with the development of new training opportunities and the implementation of new analytical approaches. One of Europe’s leading scientific management SMEs (GABO:mi) will facilitate the management of EU-AIMS and a distinguished international Scientific Advisory Board will provide input and guidance to ensure that we integrate effectively with other ongoing international initiatives, and collaborate constructively with patient groups and international consortia and experts. For example, we will actively collaborate with the patient group, Autism Europe, and the Autism Genetic Resource Exchange (AGRE). Thus, we propose an innovative program that will have genuine impact on academic, pharmaceutical, and regulatory stakeholders in the field of ASD. By the end of the 5 year project we expect to provide novel validated cellular assays, animal models, new fMRI methods with dedicated analysis techniques, new PET radioligands, as well as new genetic and proteomic biomarkers for patient-segmentation or individual response prediction. We will provide a research network that can rapidly test new treatments in man. These tools should provide our EFPIA partners with an added competitive advantage in developing new drugs for ASD.

Meyer-Lindenberg A. EU - Europäische Union 282586: ROAMER: A Roadmap for Mental Health Research in Europe. 10/2011-09/2014.

On the regional level, Europe has one of the highest levels of resources for mental health care. Despite this, the high burden and impact of mental disorders in Europe is expected to rise. “ROAdmap for Mental health Research” (ROAMER) is designed to develop a comprehensive, consensus-based roadmap to promote and integrate mental health and well-being research in Europe. Research advances and innovations are to be devoted to decreasing the burden of mental disorders and increasing the mental health and well-being of Europeans. ROAMER will combine a neutral, fact-based methodology with extensive stakeholder involvement in consultation and dissemination. During the kick-off phase, the methodology (including comprehensive EU-wide indicators to assess the current state of the art, gaps and advances) and the desired situation (scoping and objectives) will be finalised. Secondly, the current state of the art will be examined, using these tools. In the third phase, the desired situation will be compared with the current situation to identify gaps and advances. Phase four prioritises these gaps and advances, as well as solutions. In the fifth phase, this information is translated into roadmaps covering infrastructures, capacity building and funding strategies for scientific areas relevant to mental health and well-being: biomedical, psychological, social, economic and public health. Geographical, interdisciplinary, developmental, gender and age perspectives will be taken into account. To achieve consensus among a broad group of scientists, service users, carers, government and funding institutions and other stakeholders, ROAMER uses web-based survey’s, scientific workshops, scientific advisory board meetings, stakeholder meetings, consensus meetings, and policy meetings. The consortium consists of leading experts in the field, and is well balanced in terms of geographical distribution and complementary expertises across all relevant aspects of mental health research.

Schilling C. Ruprecht-Karls-Universität Heidelberg : Olympia Morata Programm: Neurobiologische Entstehungsmechanismen der psychophysiologischen Insomnie. 04/2010-03/2012.

Schizophrenie und Borderline Persönlichkeitsstörung sind psychiatrische Erkrankungen, die mit Defiziten sozialer Kognitionen einhergehen. Das vorliegende Projekt dient der Erforschung möglicher kausaler „Bottom-up“ und „Top-Down“ Faktoren. Zu diesem Zweck sollen sowohl neuronale Korrelate von Gesichtsimitation als auch die Beeinflussbarkeit sozial-kognitiver Prozesse durch Induktion von emotionaler Valenz und Arousal bei Schizophrenie und Borderline Persönlichkeitsstörung untersucht werden. Der Vergleich beider Patientengruppen ermöglicht die Identifikation von sowohl störungsübergreifenden, als auch störungsspezifischen Pathomechanismen sozialer Kognition.

Schizophrenia patients suffer from a broad variety of cognitive deficits that are very often resistant to antipsychotic treatment and interfere with the social and vocational rehabilitation. An international consensus initiative elaborated a comprehensive set of neuropsychological tests, the MATRICS battery (Measurement And Treatment Research to Improve Cognition in Schizophrenia) in order to improve treatment research (1). Besides the domains represented in the MATRICS battery, it has been shown that metacognitive capacities are impaired in schizophrenia, leading to a reduced ability to select appropriate responses, to appraise and weigh information effectively and to cope with cognitive limitations. Metacognitive impairments, (2) such as a self-serving attributional bias, hasty decision making (jumping to conclusion: JTC), a bias against disconfirmatory evidence (BADE) (3), overconfidence in errors, metamemory alterations (4;5), and finally deficits in mentalizing and social cognition („theory of mind“: ToM) (6;7), are thought to contribute to development and maintenance of delusions (8-10). Specific therapeutic interventions to improve metacognitive functions have been developed and tested in several controlled trials (11). In the present application, we mainly focus on ToM-deficits and the JTC-bias.
