- <i>Background:</i> Ischemic stroke is the leading cause of mortality worldwide and a major contributor to neurological disability and dementia. Terutroban is a specific TP receptor antagonist with antithrombotic, antivasoconstrictive, and antiatherosclerotic properties, which may be of interest for the secondary prevention of ischemic stroke. This article describes the rationale and design of the Prevention of cerebrovascular and cardiovascular Events of ischemic origin with teRutroban in patients with a history oF ischemic strOke or tRansient ischeMic Attack (PERFORM) Study, which aims to demonstrate the superiority of the efficacy of terutroban versus aspirin in secondary prevention of cerebrovascular and cardiovascular events. <i>Methods and Results:</i> The PERFORM Study is a multicenter, randomized, double-blind, parallel-group study being carried out in 802 centers in 46 countries. The study population includes patients aged ≥55 years, having suffered an ischemic stroke (≤3 months) or a transient ischemic attack (≤8 days). Participants are randomly allocated to terutroban (30 mg/day) or aspirin (100 mg/day). The primary efficacy endpoint is a composite of ischemic stroke (fatal or nonfatal), myocardial infarction (fatal or nonfatal), or other vascular death (excluding hemorrhagic death of any origin). Safety is being evaluated by assessing hemorrhagic events. Follow-up is expected to last for 2–4 years. Assuming a relative risk reduction of 13%, the expected number of primary events is 2,340. To obtain statistical power of 90%, this requires inclusion of at least 18,000 patients in this event-driven trial. The first patient was randomized in February 2006. <i>Conclusions:</i> The PERFORM Study will explore the benefits and safety of terutroban in secondary cardiovascular prevention after a cerebral ischemic event.

- The benefit of endovascular thrombectomy for acute ischemic stroke with M2 segment middle cerebral artery occlusion remains controversial, with uncertainty and paucity of data specific to this population.ObjectiveTo compare outcomes between M1 and M2 occlusions in the Analysis of Revascularization in Ischemic Stroke with EmboTrap (ARISE II) trial.MethodsWe performed a prespecified analysis of the ARISE II trial with the primary outcome of 90-day modified Rankin Scale score of 0–2, which we termed good outcome. Secondary outcomes included reperfusion rates and major adverse events. The primary predictor was M2 occlusion, which we compared with M1 occlusion.ResultsWe included 183 patients, of whom 126 (69%) had M1 occlusion and 57 (31%) had M2 occlusion. There was no difference in the reperfusion rates or adverse events between M2 and M1 occlusions. The rate of good outcome was not different in M2 versus M1 occlusions (70.2% vs 69.7%, p=0.946). In a logistic regression model adjusted for age, sex, and baseline National Institutes of Health Stroke Scale score, M2 occlusions did not have a significantly different odds of good outcome compared with M1 occlusions (OR 0.94, 95% CI 0.47 to 1.88, p=0.87).ConclusionIn ARISE II, M2 occlusions achieved a 70.2% rate of good outcome at 90 days, which is above published rates for untreated M2 occlusions and superior to prior reports of M2 occlusions treated with endovascular thrombectomy. We also report similar rates of good outcome, successful reperfusion, death, and other adverse events when comparing the M1 and M2 occlusions.

- The goal of the analysis of revascularisation in ischaemic stroke with EmboTrap study (ARISE I) was to demonstrate the effectiveness of EmboTrap. Methods ARISE I was an open label, single arm, multicentre, prospective study for the treatment of acute stroke due to large vessel occlusion. The primary outcome was revascularisation of the target vessel as measured by the modified thrombolysis in cerebrovascular infarction (mTICI) score of at least 2b following thrombectomy with EmboTrap. For comparison of the ARISE I results a meta-analysis of eight randomised controlled trials was performed. Results ARISE I enrolled 40 patients. Their baseline characteristics that are predictors of stroke outcome and procedure timings in ARISE I were similar to those reported in recent randomised controlled trials. The primary outcome, good revascularisation rates (mTICI 2b/3 scores) after three or fewer passes with EmboTrap were 75% (95% confidence interval (CI) 62–88%), which is the same as 74% found in randomised controlled trials (difference of 0.8%, P = 0.95). After additional EmboTrap passes or the use of another device mTICI 2b/3 scores rose to 85% (95% CI 74–96%), which was also similar to the randomised controlled trials (difference 11%, P = 0.38). The high revascularisation rates in ARISE I converted into 64% good clinical outcomes (modified Rankin scale ≤2) compared to 50% in randomised controlled trials (difference 14%; 95% CI –13.7–41.7%; P = 0.32). Conclusions ARISE I demonstrates that thrombectomy using the EmboTrap stent retriever yields similar results to devices that were used in recent randomised controlled trials for the treatment of stroke due to large vessel occlusions.

- A considerable proportion of stroke patients have unfavorable outcomes despite substantial reperfusion during mechanical thrombectomy for large vessel occlusion. This study aimed to determine predictors of unfavorable outcomes despite substantial reperfusion (modified thrombolysis in cerebral infarction score of ≥2b). Methods We conducted a post hoc analysis of Analysis of Revascularization in Ischemic Stroke With EmboTrap, a prospective, multicenter study on the efficacy of the EmboTrap revascularization device. We included patients with anterior large vessel occlusion, substantial reperfusion within three passes, and 3-month follow-up. Univariate and multivariate logistic regression analyses were performed to determine independent predictors of dependency or death (modified Rankin Score 3–6) at 90 days. Results Of the 176 patients included in the study, 124 (70.45%) achieved modified Rankin Score of 0–2 at 90 days and 52 (29.6%) had modified Rankin Score of 3–6. On univariate analysis, patient age and initial National Institutes of Health Stroke Scale score were significantly higher in the modified Rankin Score of 3–6 groups (71.4 ± 11.3 years vs. 66.0 ± 13.1 years, 0.01; 18.9 ± 4.13 vs. 14.6 ± 4.36, p < 0.01, respectively). Mean number of passes and symptomatic intracranial hemorrhage were also higher in patients with modified Rankin Score of 3–6 (2.46 ± 1.42 vs. 1.65 ± 0.9, p < 0.01; 13.5% vs. 2.4%, p = 0.008). On multivariate analysis, initial National Institutes of Health Stroke Scale score and mean number of passes and were independent predictors of modified Rankin Score of 3–6 at 90 days. Conclusion More severe initial neurologic deficit and higher number of passes in patients with substantial reperfusion were independent predictors of dependency or death. These findings highlight a reduction in the number of passes required to achieve reperfusion as a therapeutic target to improve the outcome after thrombectomy.

- First-pass effect (FPE), restoring complete or near complete reperfusion (modified Thrombolysis in Cerebral Infarction (mTICI) 2c-3) in a single pass, is an independent predictor for good functional outcomes in the endovascular treatment of acute ischemic stroke. The economic implications of achieving FPE have not been assessed.ObjectiveTo assess the economic impact of achieving complete or near complete reperfusion after the first pass.MethodsPost hoc analyses were conducted using ARISE II study data. The target population consisted of patients in whom mTICI 2c–3 was achieved, stratified into two groups: (1) mTICI 2c–3 achieved after the first pass (FPE group) or (2) after multiple passes (non-FPE group). Baseline characteristics, clinical outcomes, and healthcare resource use were compared between groups. Costs from peer-reviewed literature were applied to assess cost consequences from the perspectives of the United States (USA), France, Germany, Italy, Spain, Sweden, and United Kingdom (UK).ResultsAmong patients who achieved mTICI 2c–3 (n=172), FPE was achieved in 53% (n=91). A higher proportion of patients in the FPE group reached good functional outcomes (90-day modified Rankin Scale score 0–2 80.46% vs 61.04%, p<0.01). The patients in the FPE group had a shorter mean length of stay (6.10 vs 9.48 days, p<0.01) and required only a single stent retriever, whereas 35% of patients in the non-FPE group required at least one additional device. Driven by improvement in clinical outcomes, the FPE group had lower procedural/hospitalization-related (24–33% reduction) and annual care (11–27% reduction) costs across all countries.ConclusionsFPE resulted in improved clinical outcomes, translating into lower healthcare resource use and lower estimated costs.
