The Challenge
Transforming Care for Rheumatoid Arthritis Patients with Multi-Drug Resistance

Rheumatoid Arthritis (RA) is the most common chronic inflammatory joint disease, affecting approximately 1% of adults worldwide—that's over 22 million people globally and 7 million in the EU alone. The societal burden is immense, with RA responsible for over 10,000 disability-adjusted life years (DALYs) and costing the EU an estimated €55 billion each year.
Despite significant advances in therapy, about one-third of RA patients are forced to give up work within five years of diagnosis—primarily because their disease does not respond to available treatments. This phenomenon, known as multi-drug resistance (MDR), leaves many patients facing disability, unemployment, and ongoing pain.
Our Mission: Tackling Multi-Drug Resistant RA
The MDR-RA project aims to revolutionize the way we understand and manage RA patients with multi-drug resistance.
Our objective is to:
- Identify the clinical and molecular phenotypes that lead to MDR in RA, allowing us to predict, prevent, or better manage resistance.
- Integrate cutting-edge molecular pathology with clinical, psychosocial, pain perception, and imaging data from existing clinical cohorts.
- Develop holistic, predictive models (iCare-RA) to support personalized treatment decisions and improve patient outcomes.Pioneering Research, Real-World Impact
MDR-RA will test the transformative potential of the iCare-RA model in a prospective randomized trial, comparing it directly with the current standard of care. We will also explore the future implementation of iCare-RA with early economic modelling to ensure sustainability and value for society.
Advancing Science and Care—Together
With a robust management and communication strategy, MDR-RA is committed to:
- Driving scientific discovery beyond the project’s duration
- Facilitating adoption by patients, healthcare professionals, policymakers, and regulators
- Shaping a future where no RA patient is left behind due to treatment resistance
Join us in transforming the future of Rheumatoid Arthritis care.
The Project
MDR-RA: Advancing Treatment for Drug-Resistant Rheumatoid Arthritis

MDR-RA is a European research initiative tackling multi-drug resistant rheumatoid arthritis—an under-researched, high-burden condition. The project aims to uncover the roots of treatment resistance and develop personalized care strategies to improve patient outcomes and redefine RA management.
By uniting academia and industry, MDR-RA drives innovation in diagnostics and therapies while building a lasting resource for future research. Through strong stakeholder engagement and targeted communication, the project ensures its breakthroughs reach clinicians, researchers, industry, and patients.
We are developing a robust dataplatform to harmonize and integrate diverse rheumatoid arthritis datasets,continuously updated with new data from ongoing studies. Using advancedanalytics and data science, we ensure high-quality, standardized, and interoperabledata—laying the foundation for predictive modelling and breakthrough MDR-RAresearch.

The Output
Tackling Multi-Drug Resistant Rheumatoid Arthritis (MDR-RA)

Multi-DrugResistantRheumatoid Arthritis (MDR-RA) affects around 1.5 million people in the EU, with up to 50% experiencing treatment failure and annual costs soaring. The MDR-RA project offers a comprehensive, evidence-based response to this urgent healthcare challenge.
ATwo-Phase MDR-RA Approach
Observational Phase
Interventional Phase
Holistic, AI-Enabled Decision Support
Powered by Collaboration from synergies from four Horizon Europe consortia to ensure robust integration and broader impact across the EU healthcare ecosystem.
A Two-Phase Approach
Observational Phase: Building the Foundation
In Phase 1, MDR-RA draws onEurope’s largest clinical and molecular data sets—over 25,000 RA patients from16 centers—to tackle treatment resistance.
Alongside this, we’re enrolling anew observational cohort of 80 RA patients and using specialized bio banks to deepen insights.
FocusAreas:
- Clinical & Imaging Models: Identifying early predictors of resistance.
- Molecular Subtypes: Defining biological profiles from blood and tissue samples.
- iCare-RAIntegration: Merging data into a predictive tool for personalized care.
This phase lays the scientific foundation for smarter, earlier intervention in RA.
Interventional Phase: Validating iCare-RA in Practice
Building on observational insights,MDR-RA moves into clinical validation to test iCare-RA in real-world care.
We’ll run a pilot randomized controlled trial with 100s of RA patients, comparing standard care toiCare-RA-supported treatment.
Objective:
- Validate iCare-RA: Assess how well the tool supports personalized treatment decisions and improves outcomes in MDR-RA compared to usual care.
This phase is key to proving iCare-RA’s real-world value in transforming RA management.
iCare-RA:Smarter Decisions, Better Outcomes
iCare-RA is an AI-powered tool that combines clinical, imaging, and molecular data to help clinicians:
- Predict treatment failure early
- Personalize therapy for each patient
- Minimize ineffective treatments and drug overuse
Validated in real-world care, iCare-RA aims to transform decision-making for complex RA cases.
Impactful Outputs
DrivingLasting Impact in RA Care
MDR-RA goes beyond patient-level care to support system-wide change in managing multi-drug resistant RA.
KeyGoals:
- Economic Modeling: Assess cost savings, treatment efficiency, and long-term outcomes with iCare-RA.
- ImplementationFramework:Develop a roadmap for clinical adoption, with training and stakeholder strategies.
- OpenBiomedical Resource: Share a rich dataset of clinical, imaging, and molecular profiles to drive future research and innovation.
These efforts ensure MDR-RA delivers sustainable tools, scalable solutions, and lasting value for health systems and RA care across Europe
The Impact
MDR-RA is transforming care—offering real hope to patients, families, and healthcare systems across Europe.

MDR-RA targets a major challenge in rheumatoid arthritis: multi-drug resistance. By uncovering why treatments fail and closing clinical gaps, it aims to transform care and reduce disease burden.
Key Impacts:
- Scientific breakthrough:Advances understanding of treatment-resistant RA and boosts translational research.
- Improved care:Supports accurate diagnosis and tailored therapies for better outcomes.
- Economic impact:Optimizes treatment use—potentially saving €10 billion and 2,000 DALYs annually in Europe.
- Stronger networks:Forges lasting ties across research, industry, and patient communities.
- Sustainable tools:Provides valuable data and resources for future innovation.
MDR-RA paves the way for truly personalized RA treatment—with lasting benefits for patients and health systems.
WhyMDR-RA Matters
RA affects over 7 million people in the EU and is a top cause of disability, with one in three unable to work within five years—costing Europe €55 billion annually.
Around20% of patients have multi-drug resistant (MDR) RA, facing double the costs and a 30% drop in quality of life.
MDR-RA tackles this urgent issue by identifying what drives treatment resistance and developing iCare-RA—a personalized care algorithm to match patients with effective therapies and prevent long-term damage.
The project also supports smarter use of expensive drugs, informs new treatments ,and guides sustainable health policy—backed by early economic modeling.
Impact on Patients and Society
MDR-RA brings real, lasting benefits by advancing precision medicine in rheumatoid arthritis. It aims to improve treatment response, avoid harmful drug exposure, and prevent long-term disability from delayed disease control.
For patients, this means quicker access to effective therapies, fewer trial-and-error cycles, and better protection of mobility and quality of life.For society, it means reducing wasteful healthcare costs and improving the efficiency of national health systems.
The project also drives innovation by identifying new drug targets and diagnostics.With patient voices from the EULAR-PARE Network guiding the work, MDR-RA ensures that care remains truly patient-centered.
