What is PROST?
PROST is a multicentre, randomized, open-label, blinded outcome, adaptive, non-inferiority trial comparing the pRESET stent-retriever with the Solitaire stent-retriever for large vessel occlusion stroke treatment.

PROST is the first randomized clinical trial aiming to compare a novel versus an established stent-retriever technology, establishing a new scientific benchmark for stroke device trials.
Thrombectomy with the pRESET stent-retriever was found to be non-inferior to thrombectomy with the Solitaire stent-retriever in terms of flow restoration and disability reduction in patients with large vessel occlusion stroke (LVOS).
The PROST Trial led to the FDA clearance of the pRESET device on January 20th 2023 with labels for improvements in both revascularization and clinical outcomes.
