Pulmonary Hypertension (PH), particularly Pulmonary Arterial Hypertension (PAH), presents a fatal complication in chronic diseases, affecting 1 in 50,000 individuals, predominantly at a young age and more often in females. The underlying genetic link involves mutations in the bone morphogenetic protein receptor type 2 (BMPR2) gene, disrupting BMP signaling. The PHAEDRA-IMPACT consortium aims to understand PH and PAH. The Research The research focuses on understanding PAH through the transforming growth factor-β (TGFβ) signaling pathway, particularly influenced by mutations in the bone morphogenetic protein receptor type 2 (BMPR2) gene, prevalent in heritable and some non-hereditary PAH cases. The PHAEDRA initiative identified compounds that modulate the TGFβ/BMP balance, showing efficacy in restoring endothelial function and reversing pulmonary vascular remodeling in preclinical models, though not curing PAH, making early detection crucial. PHAEDRA has identified biomarkers for timely diagnosis and personalized treatment. PHAEDRA-IMPACT will enhance early detection using non-invasive risk assessments, imaging, and biomarker profiling to detect pre-capillary PH. Precision medicine will guide tailored therapies based on advanced imaging and biomarker analyses, addressing disease progression variability among predisposed individuals. Additionally, patient-derived induced pluripotent stem (iPS) cells will be used in 3D culture models of lung and heart tissues to uncover PAH mechanisms and identify therapeutic targets. This comprehensive approach aims to advance our understanding of PAH pathogenesis, accelerate drug development, and enable personalized treatment and preventive strategies for individuals at risk or affected by PH.

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.
