The European Rare Diseases Research Alliance (ERDERA) aims to improve the health and well-being of the 30 million people living with a rare disease in Europe, by making Europe a world leader in Rare Disease (RD) research and innovation, to support concrete health benefits to rare disease patients, through better prevention, diagnosis and treatment. This Partnership will deliver a RD ecosystem that builds on the successes of previous programmes by supporting robust patient need-led research, developing new diagnostic methods and pathways, spearheading the digital transformational change connecting the dots between care, patient data and research, while ensuring strong alignment of strategies in RD research across countries and regions. Structuring goal-oriented public-private collaborations targeted at interventions all along the R&D value chain will ensure that the journey from knowledge to patient impact is expedited, thereby optimising EU innovation potential in RD. To support its ambition and missions ERDERA has been designed as a comprehensive and integrated ecosystem of which structure can be compared to an institute encompassing three main parts: (i) funding, (ii) internal (in house) Clinical Research Network that implements research activities targeting clinical trial readiness of RDs and accelerating diagnosis and translation of research discovery into improved patient care, and (iii) related supporting services (Data, Expertise, Education and Training) as well as an acceleration hub that serve external and internal RD community, all supported by all-embracing coordination and strategy and foundational (inter)national alignment.

There is an increasing prevalence of chronic diseases caused by undesired immune reactions (>10%) with high burden for the both patients (chronicity, organ failure, early death, decreased QoL) and society (EU:>100 bn €/a direct health costs) as current therapies are limited in efficacy and do not reshape sustainably the disturbed immune balance. Our ultimative goal is to develop a safe and efficient cell therapy based on genome-edited T cells with redirected specificity to sustainably combat IgA nephropathy (IgAN) - the most common glomerulonephritis and one of the most common causes of end-stage renal disease with unmet medical need. Our specific cell therapy approach is also suitable for other diseases with selective B-cell pathogenesis, such as IgA myeloma, IgA related celiac disease and rheumatoid arthritis, but as a blueprint also for diseases of other Ig classes (e.g. IgG4). Our novel concept offers a specific form of immunosuppression via Ig-(sub)class targeting & glycosylation targeting with redirected T cells in autoimmune diseases. Methodically, we benchmark three promising genome editing technologies, develop new standards for safety assessment and preclinical performance evaluation. At the end we will have a lead candidate of a new "living drug" product envisioned as a one-time treatment for IgAN and other IgA-associated that will be ready to enter clinical FIH trials (entry into TRL6). In addition, geneTIGA delivers enabling technology toolboxes with exploitation options beyond of the core project. They might de-risk and accelerate the development of next-generation gene and cell products in general. The project has thus, besides its scientific value, a high impact not only on the affected patients with IgAN and related immune diseases, but also for the European society by reducing the health economic burden caused by progressive chronic kidney disease, as well as by triggering innovation and business options in Europe's biotech and pharma field.
