The SQUEEZE consortium comprehensively addressed how biomarkers can be used to optimize disease modifying antirheumatic drugs (DMARDs) for rheumatoid arthritis (RA). RA is a chronic immune-mediated disease with enormous health-related quality of life and socioeconomic impact. Through nine dedicated work packages SQUEEZE integrates to validate clinical, laboratory, molecular, digital and behavioural biomarkers to enable the recognition of patients with high likelihood of response to treatment and the selection of the drug with highest chance of benefit for an individual patient; and as such improve efficacy and safety of existing therapies (by squeezing the most out of existing drugs) in synergy with other EU-wide activities.
