EULAR Recommendations: EULAR/ACR Collaborative Projects
For initiatives with international relevance, the relevant EULAR Committee seeks collaboration with the Quality of Care committee of the American College of Rheumatology (ACR). This cooperation includes the development and validation of criteria sets for the development of recommendations regarding conducting clinical trials.
EULAR and ACR strive for a transparent and collaborative relationship in order to avoid overlaps and to identify and promote synergies.
2022-2023 ACR/EULAR Collaborative Criteria Projects call for proposals is now open.
