The research and innovation (R&I) priorities focus on enhancing satellite communication (SatCom) and Earth Observation (EO) capabilities through advanced technologies. For SatCom, this includes end-to-end mission capabilities such as seamless integration with terrestrial networks, inter-satellite connectivity, reconfigurable payloads, and interoperability with 5G/6G networks. Emphasis is placed on building flexible testbeds and ensuring satellites can act as nodes in distributed systems. For EO, key areas include on-board processing using AI and machine learning for multi-spectral image analysis, improved data transmission, and standardized ground segment interfaces. Digitalisation of EO instruments and miniaturization of equipment are also important. Cross-cutting innovations for both EO and SatCom involve developing secure, flexible, and environmentally efficient systems, with a focus on shared resources, intelligent data fusion, and high-performance processing technologies.

Advancing innovative interventions for mental, behavioural and neurodevelopmental disorders
ClosedCode: 37593 | Identifier Code: HORIZON-HLTH-2025-03-DISEASE-02-two-stage | Programme name: 2939 | Sub-program: Health (Cluster 1) (2021-2027) | Start submission calls: 22/05/2025 | End submission calls: 16/09/2025
Mental, behavioural and neurodevelopmental disorders, that include for example severe depression, anxiety, schizophrenia, psychosis, post-traumatic stress disorder (PTSD), addictive behaviours (drugs, alcohol, gaming and others), obsessive-compulsive disorder, eating disorders and autism spectrum disorder are a high burden for patients, health systems and society, and remain unmet medical needs.
More innovative, safer and more effective therapeutic and relapse-preventing solutions based on active substances are required, as for example for mental disorders many available treatments show modest efficacy, non-negligible side effects, discontinuation problems and high relapse rates

Advancing cell secretome-based therapies
ClosedCode: 37580 | Identifier Code: HORIZON-HLTH-2025-01-TOOL-02 | Programme name: 2939 | Sub-program: Health (Cluster 1) (2021-2027) | Start submission calls: 22/05/2025 | End submission calls: 16/09/2025
Secretome-based therapies have emerged as a promising alternative to cell-based therapies.
The secretome of cells is defined as the repertoire of molecules and biological factors that are secreted into the extracellular space and has been shown to be a key factor for therapeutic activity due to its paracrine effects.
The potential to manufacture, store and use secretome factors as off-the-shelf products, while maintaining the therapeutic benefits of cells but with fewer safety concerns, has placed the secretome at the forefront of regenerative medicine. Different cell secretomes or parts thereof have been the subject of clinical trials, but there is currently no regulatory-approved secretome-based therapy owing to several challenges.
Currently, for the majority of secretome-based therapies, the main bottlenecks are: the incomplete understanding of their mode of action, their reproducibility due to a lack of standardised manufacturing processes and a lack of potency- and quality assurance assays. Additional limitations are the characterisation of the bioactive factors and the optimisation of the delivery strategies.

Enhancing cell therapies with genomic techniques
ClosedCode: 37577 | Identifier Code: HORIZON-HLTH-2025-01-TOOL-01 | Programme name: 2939 | Sub-program: Health (Cluster 1) (2021-2027) | Start submission calls: 22/05/2025 | End submission calls: 16/09/2025
Therapies based on cells, stem cells or somatic cells, have been shown to be highly effective as therapeutics for a variety of health conditions.
However, bottlenecks remain which currently hamper their safe and efficient application on a large scale.
Genome- and epigenome editing have great potential to overcome some of these bottlenecks and to lead to the next-generation of cell-based therapies.
Advancing the frontier of cell-based therapy with these tools and further translation of such research into clinically viable solutions may open up a new era of innovative therapies.

Digitalisation of conformity assessment procedures of medical devices and in vitro diagnostic medical devices
ClosedCode: 37574 | Identifier Code: HORIZON-HLTH-2025-01-IND-02 | Programme name: 2939 | Sub-program: Health (Cluster 1) (2021-2027) | Start submission calls: 22/05/2025 | End submission calls: 16/09/2025
The regulations on Medical Devices (MDR) and In Vitro Diagnostic Medical Devices (IVDR) have introduced stricter regulatory requirements in view of ensuring a high level of patient safety and public health. The implementation of the new regulatory requirements still remains a challenge for manufacturers.
SMEs face particular challenges as they have limited resources to adapt to the new framework.
One of the main issues reported by manufacturers is the complexity and perceived unpredictability of the conformity assessment procedure involving a Notified Body.

Tackling high-burden for patients and under-researched medical conditions
ClosedCode: 37565 | Identifier Code: HORIZON-HLTH-2025-01-DISEASE-07 | Programme name: 2939 | Sub-program: Health (Cluster 1) (2021-2027) | Start submission calls: 22/05/2025 | End submission calls: 16/09/2025
A number of medical conditions fail to be recognised and/or be correctly diagnosed in a significant proportion of patients.
As a consequence, they are inadequately treated and often can become a chronic and high burden for the patient.
These medical conditions, including:
- myalgic encephalomyelitis/chronic fatigue syndrome,
- autism,
- gynaecological diseases,
- low back pain,
- other,
may be insufficiently researched even though they manifest with high prevalence.

Development of antibodies and antibody-derived proteins for the prevention and treatment of infectious diseases with epidemic potential
ClosedCode: 37534 | Identifier Code: HORIZON-HLTH-2025-01-DISEASE-03 | Programme name: 2939 | Sub-program: Health (Cluster 1) (2021-2027) | Start submission calls: 22/05/2025 | End submission calls: 16/09/2025
As shown by the COVID-19 pandemic, infectious diseases remain a major threat to health and health security in the EU and globally.
Viral disease emergence is expected to accelerate due to among other, climate change, and thus a proactive approach to the development of antiviral prophylactics and therapeutics in preparedness for future infectious disease outbreaks is needed.
The availability of antibodies and antibody-derived proteins would provide a critical preparedness measure against future health threats, due to infectious disease epidemics or pandemics.
