PROOF
Penumbral Rescue by Normobaric O=O Administration in Patients With Ischaemic Stroke and Target Mismatch ProFile: A Phase II Proof-of-Concept TrialThe PROOF project now seeks to demonstrate that NBHO (high-flow 100% oxygen at >45 L/min via a non-rebreather mask, or FiO2=1.0 for intubation/ventilation) reduces infarct growth from baseline to 24 hours compared to standard treatment if administered at 3 hours after onset of anterior circulation IS, in patients with proximal vessel occlusion and salvageable tissue at risk. The study is multi-center, adaptive phase-IIb, randomized, open-label with blinded-endpoint (PROBE design).
The primary efficacy criterion will be infarct growth from baseline to 24 hours. Secondary endpoints will be NIHSS 24h, categorical shift in the pre-stroke modified Rankin Score, QoL and cognition at day 90. Potential surrogate biomarkers, health economics and societal impacts will be assessed. If NBHO proves its neuroprotective potential in this selected population, phase-III trials in all IS patients may be undertaken. Considering its low costs and ease of use, NBHO may impact stroke care worldwide.
