Improvement of international stroke research networks can increase efficiency and reduce waste in clinical trials of stroke treatments.
Conducting investigator-led randomised trials is becoming increasingly complex, due to the need for large sample sizes and growing complexity of the regulatory and funding environment. This complex context poses a serious risk of inefficiency in stroke research, unless initiatives to increase collaboration among European stroke researchers are undertaken.
Considering this, the ESO Trials Network Committee established a structure to improve multinational European stroke research collaboration for the long-term – the ESO Trials Alliance (ESOTA).
The management of trials is not performed by ESOTA, but remains with individual investigators and their teams.
