Four perspectives, one shared goal
Clinical care, patient experience, research and institutions work together in One4 with clearly defined roles, rights and transparent data access.
For treatment centers and researchers
Complex diseases require structured, long-term care across many centers, many patients and many years.
One4Care brings care, documentation and research onto one shared platform without centers giving up control over their data.

Care, studies and monitoring in one place
One4 enables participating centers to follow up patients according to agreed care plans, without duplicate documentation in registries or secondary study platforms. Governed by medical societies, One4 offers a fully integrated system that brings together follow-up care, documentation, regulatory needs, studies and internal research, always under full data sovereignty and control of participating centers.
Central digital processes
Digital workflows bundle care, documentation, study readiness and exchange in one shared workflow.
- Structured care-plan management and appointment coordination
- Systematic ePROM collection fully integrated into routine care
- Study recruitment via the platform: identify patients, obtain consent, support participation
- Cross-center expert exchange and therapy recommendation boards
For patients and families
Living with a complex disease means more than appointments and therapy plans. It means everyday life, uncertainty and experiences that no laboratory result can fully capture.

Developed together with patients and families, not just for them
The One4 App enables direct communication with the treatment team, appointment management, study access, community exchange, tracking and much more.
You can actively change something
Clinical studies are the path through which new knowledge about disease courses and therapies emerges. Those who participate help future patients and often benefit themselves. Bring in your perspective.
You stay in control
Consent is digital and blockchain-secured through eConsent. You can see at any time which data you have shared for which purpose and can withdraw consent just as easily.
For life-science partners
Innovative therapies need evidence from clinical development through long-term post-approval evaluation.
One4 is not a registry. One4 is a data ecosystem for all phases of the medical product lifecycle, fully integrated into routine care. This saves resources and enables innovative, future-ready study design.

Data access is rule-based and predictable
Defined by a public charter and a transparent partner contribution model, with no bilateral price negotiations for data packages.
Partners actively contribute to data standards and governance and can view recruitment, performance and safety events through their own dashboard at any time.
Become part of an ecosystem that does not sell evidence, but builds it together.
For health institutions
Health-policy decisions and regulatory evaluations require reliable, real-world data. One4 Health creates the infrastructure that provides this data basis.

Robust evidence for faster therapy development
Innovative therapies reach care faster today than the surrounding structures can grow. A gap opens between approval, reimbursement and care reality, and it can only be closed with reliable data from actual treatment settings.
A shared knowledge base
One4 Health builds the infrastructure that creates this data basis: independent, interoperable and aligned with regulatory requirements. Health-policy steering, regulatory evaluation and needs-based care all require the same foundation: robust, practical evidence. One4 Health provides it and understands itself as part of an international real-world-evidence infrastructure, complementary to existing processes.
This creates a shared knowledge base that all stakeholders can rely on, from drug safety and benefit assessment to care steering.
