It is expected that certain existing assets will be used as background in this action. Such background assets may include, but are not limited to, cell manufacturing technologies, gene editing platforms, scaffold materials, encapsulation systems, and delivery and release technologies, among others. The exact nature of the background to be brought into the project will depend on the proposals presented by the public consortia. Therefore, beneficiaries intending to participate in this action need to be comfortable with the principle that ownership of specific deliverables / project results which would be considered direct improvements to a beneficiary’s background asset, will need to be transferred back to the beneficiary who contributed the background asset to the project. Provision for and conditions relating to such transfers should be specified in the project’s consortium agreement.
Scope:
Challenges and Background
T1D is an autoimmune disease that destroys insulin-producing pancreatic beta-cells, leading to lifelong insulin dependence. Despite advances in technology, achieving stable blood glucose levels remains challenging, which increases the risk of severe complications, and this in turn impacts negatively on daily life, work productivity, and mental health, and contributes to stress, anxiety, and depression.
Beta-cell replacement therapy offers a promising path towards a functional cure, but critical challenges must be addressed, including the need for renewable cell sources, optimised islet preparations, standardised manufacturing protocols, robust monitoring tools, sustainable reimbursement models, and trained healthcare professionals to manage complex treatments. These challenges align with key priorities from the Draghi Report , emphasising harmonised regulatory pathways, early engagement with HTA bodies, standardised manufacturing processes, and patient-centred clinical endpoints. Without urgent action, the full potential of beta-cell therapies will remain unrealised.
Key Objectives:
1) Establishing standardised criteria and analytical methods:This objective aims at developing standardised criteria and analytical methodologies to detect, quantify, and characterise unintended bystander cells and impurities in stem cell-derived or beta-cell therapies for T1D. This work is intended to support the field at large by generating reference materials, optimising detection technologies, and defining regulatory-compliant thresholds that can inform future research and development—not to advance a specific product. The focus is on creating translatable, broadly applicable tools and standards that ensure safety, consistency, and quality. Engagement with the European Medicines Agency (EMA) is encouraged to facilitate the regulatory relevance and potential adoption of these methodologies in preclinical and clinical research settings.
2) Enhancing graft survival and immune tolerance:This objective aims at developing immune-modulating strategies that support the long-term survival of beta-cell grafts and promote immune tolerance. This work is intended to generate insights, tools, and models that advance scientific understanding and inform future therapeutic approaches. Activities will include retrospective analyses of human cadaveric islet transplantation cohorts from different European countries and healthcare systems to support biomarker discovery and predictive modelling. Key biomarkers – such as continuous glucose monitoring (CGM) metrics, C-peptide levels, HbA1c, inflammatory cytokines, immune cell subsets, beta-cell-specific autoantibodies, and gene expression profiles – will be explored to identify indicators of graft survival, immune tolerance, and beta-cell function. In addition, a prospective study may be designed to identify novel biomarkers related to glycaemic variability, immune regulation, insulin independence, beta-cell regeneration, and inflammatory pathways. These efforts are aimed at supporting the development of robust monitoring tools and decision-making frameworks, not at advancing a therapeutic candidate toward clinical use.
3) Advancing manufacturing and quality control:The objective is to establish robust cryopreservation techniques that preserve the viability and functionality of beta-cells post-thaw, with an emphasis on the identification and validation of biomarkers to guide and assess these processes. Building on this, the applicants should aim to develop and optimise scalable, cost-effective manufacturing methodologies and quality control frameworks that support the production of consistent, high-quality beta-cell therapy materials in a research and innovation context. The goal is to generate foundational knowledge, technical standards, and reference systems, not to develop specific commercial products. Additionally, the consortium should work toward establishing standardised criteria for the production and quality control of excipient raw materials used in beta-cell therapy delivery systems, to ensure their stability, safety, and suitability for future clinical applications.
4) Streamlining preclinical and clinical development:This objective aims at enhancing preclinical models for allogeneic cell therapies, ensuring standardised approaches and consistent methodologies in transplantation science and surgery. The focus is on harmonised regulatory approval, defining patient demographics for broader accessibility, and tailoring treatment requirements for personalised care. Establishing definitions for insulin independence, investigating and working toward the regulatory acceptance of clinically meaningful endpoints, such as ‘Time in Range (TIR)’ and ‘Time in Tight Range (TiTR)’, and optimising clinical trial design for allogeneic therapies are essential components of the future project.
5) Implementing advanced monitoring and artificial intelligence (AI)-driven predictive tools:Leveraging real-time monitoring technologies like continuous glucose monitoring (CGM) and biosensors to assess transplant success and metabolic function, this objective aims to integrate advanced techniques from various fields, including oncology. Specifically, immune monitoring strategies used in oncology, such as immune checkpoint inhibitors and tumour biomarker profiling, will be explored to enhance the understanding of immune responses in beta-cell transplantation. AI-powered predictive models will personalise treatment plans and optimise immunosuppression regimens. Additionally, non-invasive imaging techniques, such as magnetic resonance imaging (MRI) and positron emission tomography (PET), will track graft survival and immune responses, ensuring better monitoring and management of beta-cell therapies. The action should also reinforce transparency requirements, including model interoperability, data provenance, and traceability of AI decision-making processes.
6) Defining clinically meaningful and patient-centred endpoints using real-world evidence:This objective aims at leveraging real-world data to define clinically meaningful endpoints that capture quality of life and disease burden in T1D. This includes identifying surrogate endpoints to enable clinical trials that demonstrate long-term benefits without requiring extended study durations. Additionally, generating data on the advantages of achieving normoglycemia in individuals already within target glucose ranges will help refine treatment goals and support regulatory decision-making. A small pilot study must be conducted to test these endpoints and gather initial data on their feasibility and impact.
7) Exploring reimbursement models for beta-cell therapies:This objective aims at developing initial cost-effectiveness models that highlight the potential financial and healthcare benefits of beta-cell therapies, focusing on key aspects like reduced complications and improved quality of life. Early-stage collaboration with health technology assessment (HTA) bodies, payers, and policymakers must be sought to help build a foundation for understanding the value of these therapies, laying the groundwork for future integration into healthcare systems across Europe.
8) Integration of cell therapy into diabetes care and collaborative networks:Beta-cell therapies should be integrated into standard diabetes care through specialised training for healthcare providers and the creation of a network of multidisciplinary centres across Europe. Clinical guidelines should be put in place to ensure a smooth transition from current treatments. Additionally, a network of European innovation hubs must be established to foster collaboration, knowledge exchange, and harmonised regulatory approaches, accelerating the development and clinical application of beta-cell therapies. It will also be crucial to collaborate with professional societies to define a clear clinical pathway, ensuring alignment with best practices and optimising patient outcomes across the region.
