ARENA-PRIME

2018

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.

LoDoCo2

2016
The aim of the LoDoCo2 (Low Dose Colchicine for secondary prevention of cardiovascular disease) trial was to investigate the effect of low dose colchicine (0,5 mg once daily) on the risk of myocardial infarction (fatal or non-fatal), stroke, or the need for coronary bypass or stent placement. While the precise mechanism through which colchicine mitigates major cardiovascular events remains incompletely understood, it is hypothesized that its anti-inflammatory effects contribute to risk reduction among patients with established atherosclerotic disease. LoDoCo2 stands out in several respects. It represents a large-scale randomized clinical trial conducted entirely by a non-academic network of cardiologists and a consortium of pharmaceutical companies with a focus on drug repurposing. This trial underscores the potential value of older, often cost-effective medications in advancing the development of new innovative drugs. The Research Following a median follow-up period of 3 years, the addition of colchicine to standard treatment resulted in a 30% reduction in risk of myocardial infarction (fatal or non-fatal), stroke, or the need for coronary bypass or stent placement. Patients treated with colchicine exhibited similar side effects compared to those receiving a placebo. Furthermore, no interactions were found with other commonly used drugs such as (potent) statins. In 2021, certain international guidelines had already incorporated colchicine into the secondary prevention of atherosclerotic cardiovascular disease (ASCVD). Subsequently, in 2023, the Food and Drug Administration (FDA) approved Lodoco® (colchicine) for reducing the risk of myocardial infarction (MI), stroke, coronary revascularization, and cardiovascular (CV) death in adult patients with established atherosclerotic disease or multiple risk factors for CV disease. This approval was based on published data regarding the effects of colchicine on cardiovascular events, along with insights from the LoDoCo2 trial. The LoDoCo2 investigators anticipate that colchicine will become the standard treatment for patients with coronary artery disease. The origin The LoDoCo2 trial is based on based on LoDoCo, a small Australian trial that assessed the benefits of administration of a low dosis colchicine on coronary artery disease (CAD). Colchicine is a relatively inexpensive medication commonly used for the treatment of inflammatory disease, e.g. gout. The LoDoCo2 trial was executed with a similar protocol in Australia and the Netherlands. LoDoCo2 is special in many ways; it is a large randomised clinical trial fully run by a non-academic network of cardiologists (WCN), funded by The Dutch Heart Foundation and ZonMw (Goed Gebruik Geneesmiddelen) and a consortium of pharmaceutical companies with focus on drug repurposing. Although the recruitment of patients already started before the start of the DCVA, the DCVA always has provided strong support, also in the route towards implementation. This drug-repurposing clinical trial shows that a collaborative statement from the DCVA and its partners is needed to change rules and regulations in order to make this effective, safe and cheap old treatment available for patients.

Delta Plan Heart Failure

2023
Heart failure is a severe and chronic condition were the heart is unable to pump blood around the body properly, due to a structural and/or functional abnormality of the heart. It has many different causes, with the most common being hypertension and coronary artery disease. Heart failure is an unpredictable condition with sudden exacerbations of the disease, hospitalization, and will ultimately lead to death. Proper (and early) treatment may improve the symptoms of health failure and may lead to a relatively longer and better quality of life. The origin On the cardiovascular disease research agenda, as drawn up at the initiative of the Dutch Heart Foundation in 2014 and revised in 2020, the themes “Earlier recognition of cardiovascular disease” and “Heart failure” have been placed on the agenda. The DCVA also announced the Delta Plan Heart Failure in the 2022 annual plan. This resulted in the Delta Plan Heart Failure, which is initiated and financed by the Hartstichting, the Netherlands Heart Institute, and the Dutch Cardiovascular Alliance. In this national project, healthcare professionals, researchers, and patients have joined forces and will focus on the entire continuum of the disease from prevention to palliative care. The research We expect that burden of disease can largely be reduced by addressing the following key-points: Increasing public awareness of heart failure Early detection of heart failure Stimulating the collaboration among all (different) disciplines within the field of health failure Initiation of research consortia for innovative treatment and management of heart failure patients Furthermore, this project will not only focus on positively influencing survival but also on optimizing the patient’s quality of life and will pursue a strategic and operational approach.
