Holland Hybrid Heart

2023

In the Netherlands, there are 250,000 patients with heart failure. Half of these patients die within five years. The best treatment: a donor heart. But: there is a great shortage of these. The Holland Hybrid Heart consortium is therefore working on an alternative: a robot heart, made of soft materials.

The research

We envision the treatment of patients with heart failure (HF) in such a way that the survival and quality of life of HF patients drastically increases. We aim to achieve this by developing a unique bioinspired total artificial heart that integrates soft robotics and tissue engineering (TE). In the long term, we foresee that this pioneering technology allows us to develop and bring to the clinic a full set of artificial motile organs and tissues that seamlessly integrate with the human body. This will be possible as the novel and exciting technologies underlying the artificial heart developed in this project - soft robotics and in situ TE - can be used to generate a broad range of artificial motile organs such as muscle structures (e.g., limbs), bowels or lungs:

The motility and flexibility in shape and size of soft robots make them suitable for mimicking motile organs. Actuators can be embedded within the elastomeric matrix of these robots without compromising their malleable properties. In addition, embodied intelligence provides direct feedback on shape and force, enabling natural behaviour.

Biocompatibility of these artificial organs is provided by TE inside the body (in situ) using biodegradable coatings or scaffolds. Such TE scaffolds are cell-free synthetic bio-resorbable implants or linings that can recruit or interact with cells from the bloodstream, leading to gradual replacement of the scaffold by fully endogenous, and thus biocompatible, tissue. Importantly, the cell-free and thus off-the-shelf availability of these scaffolds avoids the high costs and complex logistics inherent to pre-implantation in vitro TE.

The Holland Hybrid Heart (HHH) consortium will push the development of these newly emerging technologies forward and combines soft robotics and in situ TE to generate the first biocompatible, soft actuated heart. This project will deliver Proof-of-Principle for full in vivo cardiac functionality of the artificial HHH in large animals. If successful, the HHH will be available for translation to the clinic as an effective treatment for advanced HF in patients and a valid alternative for moderately effective current HF therapies. This is a quantum leap forward in the treatment of HF.

Origin

A photo in the newspaper inspired Rotterdam heart specialist Jolanda Kluin to develop a robot heart. Kluin immediately contacted the interviewee in the article, Bas Overvelde, head of the Soft Robotic Matter group at Amolf, which develops soft robots. Could he perhaps also make a heart using soft robot techniques? Overvelde believed in it and a collaboration was born. Five years ago, they received a European subsidy of more than 3 million euros. This grant started the previous EU consortium, the EU Hybrid Heart.

Last December (2023), Kluin received another 11 million euros from the Dutch government to continue the Holland hybrid heart project. The Holland Hybrid Heart has pivoted to meet the demands of that new grant and now only contains 15 Dutch consortium partners. The consortium is funded by NWA-ORC and the Dutch Heart Foundation. In-kind contributions are also provided by the DCVA, the Dutch Heart Foundation, TrailBlazers, SBMC, EVOS and EE-Labels. The executing academic partners are Erasmus MC, Amolf, TU Eindhoven, University of Twente, TU Delft and Saxion Applied University. This research is driven by patient needs and the Harteraad and Stichting Pulmonale Hypertensie will provide the connections to these patients.

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.

LEEFH

2013

Familial Hypercholesterolemia (‘FH’) is the most prevalent genetic cause of premature atherosclerotic cardiovascular disease (ASCVD). FH has an estimated prevalence of 1:300 in the general population in the Netherlands.
FH is characterized by lifelong elevation of LDL cholesterol, resulting in a profoundly increased risk of coronary heart disease (CHD) and premature death. Early identification of FH and intensive LDL cholesterol management are essential to minimize the lifetime cumulative cholesterol burden and associated risks.
FH is inherited. Typically, parents with one pathogenic mutation have a 50% chance of passing down the condition to each child. Therefore, it is essential to screen first degree relatives (children, parents, brothers & sisters) of an individual diagnosed with FH, to detect other family members who may have inherited FH.
LEEFH network
In the Netherlands we have long track record with FH index identification, cascade screening of first degree relatives and associated research activities. Stichting LEEFH support healthcare professionals pro-actively to pursue cascade screening, aiming to identify FH-patients as early as possible. LEEFH works in a voluntary network with 39 hospitals (LEEFH centres) to optimize FH care and cascade screening.
Over the years, an active database has been built up with approximately 7,000 family pedigrees and more than 37,000 FH positive tested patients. Annually, we detect ~ 300 FH+ indexes (new FH families) and 500 FH+ family members by cascade screening. A unique example of early prevention.
The Research
LEEFH supports research activities in the field of FH detection and treatment with its acquired knowledge, database and network. Recent examples of this include FH identification via central laboratory data, electronic health records and general practitioners.
We also participate in research projects with other genetic disorders in order to further improve cascade screening through knowledge sharing (for example in the consortium ‘eCG Family Clinic’ (e-Cardiovascular Genetics Family Clinic).
The Orgin
The LEEFH network is a voluntary partnership since 2013. 39 hospitals are now affiliated. Each hospital (LEEFH center) has a number of healthcare professionals with a great deal of knowledge and affinity with FH.
The LEEFH network aims to prevent (unnecessary) cardiovascular diseases by a) detecting FH family members through cascade screening and b) creating more awareness about FH.
We do a lot of knowledge sharing about FH, both among ourselves and also through regional meetings with families and general practitioners.
We have signed network agreements with ‘who’ does ‘what’ and ‘when’ in the cascade screening . The aim is to inform and support each family in the right way in the cascade screening.
The DNA diagnostics are carried out by the Amsterdam UMC. Application forms and test packages are available via Stichting LEEFH.
