IMPRESS

The GENIUS II (Generating Evidence-Based Pharmaceutical Targets and Drugs for Atherosclerosis) consortium is dedicated to studying atherosclerosis, the primary pathological condition underlying cardiovascular diseases. The consortium aims to translate identified druggable targets for atherosclerosis intervention into clinical applications. Gender specificity is a key consideration in all our studies. Our consortium's talent program is structured to provide young researchers with insights into the opportunities and challenges of cardiovascular drug development. The Research GENIUS II research integrates knowledge of dyslipidemia and associated immune responses. Our work is organized into distinct work packages that correspond to the logical steps in drug development. Each selected target from GENIUS I is strategically incorporated into this framework. Our investigations encompass in vitro and in vivo analyses to understand mechanisms, druggability, and effects on atherosclerosis. In addition to building upon GENIUS I drug targets and leads, we leverage recent innovative advancements to identify new druggable targets within male and female atherosclerotic lesions, as well as in circulating cells. State-of-the-art molecular biology techniques, including single cell sequencing and immunophenotyping, are actively employed to dissect immunometabolic processes within atherosclerotic plaques and patients. These studies will enable us to monitor the presence of drug targets at disease sites, expediting drug design and potentially identifying gender-specific biomarkers to aid disease progression monitoring and diagnosis. Subsequent studies involve testing the efficacy of small molecules, monoclonal antibodies, and siRNA against pre-selected targets from GENIUS I. We have identified small molecules and monoclonal antibodies for five targets, which will undergo toxicity and proof-of-pharmacology studies to progress towards drug development for cardiovascular patients. We have also identified three drugs affecting primary targets from GENIUS I and are assessing their potential to reduce atherosclerotic parameters in First-In-Human clinical trials. Origin This consortium was funded through the Impulse Grant program by the Dutch Heart Foundation. The GENIUS II consortium builds on the most promising targets identified in the GENIUS I consortium, with the goal of advancing these targets towards clinical application.

In preceding decades, conventional therapies have notably enhanced the survival rates of heart failure (HF) patients. However, a subset of individuals, particularly younger patients afflicted with dilated cardiomyopathy (DCM) or arrhythmogenic cardiomyopathy (ACM), still confront disease progression despite these treatments. This underscores the necessity for innovative approaches. The ARENA-PRIME initiative aims to address this gap by focusing on the development of novel gene therapies tailored to the specific disease mechanisms underlying DCM, attributed to mutations in the RBM20 and LMNA genes, as well as ACM, and associated with mutations in the DSGL2 and PKP2 genes. The goal is to progress towards first-in-human clinical trials, particularly focusing on LMNA disease, and to establish preclinical proof-of-concept for ACM therapies targeting DSGL2 and PKP2. The Research The ARENA-PRIME researchers utilize insights from previous programmes on cardiac gene therapies (e.g., inhibitory RNAs such as allele-specific short hairpin RNAs, antimiRs, etc.) and gene editing technologies (e.g., base- and prime editing) to develop novel treatments for dilated cardiomyopathy (DCM) and arrhythmogenic cardiomyopathy (ACM). This effort is supplemented by advanced research on adeno-associated viral vectors and the integration of heart tissue collections with cutting-edge sequencing technologies (like single-cell sequencing) to further explore disease mechanisms. At the beginning of the ARENA-PRIME programme, a (end-) user committee has been established, making sure that (end-)users are  closely involved in the design of the studies and the implementation of the co-created studies and deliverables. This committee meets annually alongside the program's research meetings to provide guidance to investigators on optimizing the program's outcomes for (end-) users. It addresses all feedback, inquiries, and recommendations, whether requested or spontaneous. This committee meets once per year in conjunction with the programme’s research meetings and advises the investigators about the course of the programme and what actions need to be taken in order to maximise the probability that the (end-) users will be able to utilize and/or benefit from the results. This committee addresses any comments, remarks, questions and advice they may have, solicited or otherwise. The members of the ARENA-PRIME user committee include cardiomyopathy patients and their relatives, clinicians (e.g. cardiologists), representatives from related research programs (e.g., RegMedXB, H2020-TRAIN-HEART), and industry stakeholders including biotech and pharma company representatives and venture capitalists. Supporting Young Investigators The programme prioritizes attracting and nurturing young talent, providing hands-on training and fellowship awards to facilitate their career development. Over 20 young investigators participate, benefiting from exposure to collaborative research environments. To further support this career development, five fellowship awards of 50.000€ have been granted the past three years to junior postdoctoral researchers in the laboratories of the Hubrecht Institute, University Medical Center Utrecht, Amsterdam UMC (location VUmc and AMC) and Maastricht University. Origin The former CVON-ARENA programme (2012-2017) advanced understanding of cardiac RNA species in heart failure (microRNAs, lncRNAs and circular RNAs). The CVON-ARENA programme (2012-2017) advanced understanding of cardiac RNA species, such as microRNAs, lncRNAs, and circular RNAs, in various forms of heart failure (HF). This subsequent ARENA-PRIME programme (2018-2023), funded by the Dutch Heart Foundation, targets treatment-resistant HF forms, particularly in younger patients with dilated cardiomyopathy (DCM) or arrhythmogenic cardiomyopathy (ACM). In 2023 ARIME-PRIME received a matching grant from the Dutch Heart Foundation to work on their research together with a private partners, so that they can achieve their ambitions and objectives more quickly.
