ANNEXA-I secondary analyses: andexanet benefit amplifies in highest-risk HE quartiles (NNT ~4) without amplifying thrombotic-event risk; authors propose an 11-to-1 rule.
Argatroban+DAPT vs DAPT alone in high-risk branch atherosclerosis disease (n=100): END 20.4% vs 47.1% (P=0.006), mRS 0–1 87.8% vs 68.6% (P=0.025), no excess bleeding.
JX10 phase 2a (n=90) — late-window (5–12h) thrombolytic met its primary safety endpoint (0% sICH vs 2.6% placebo) and showed a day-90 mRS 0–1 signal (40.4% vs 18.4%, P=0.03).
ANNEXA-I biomarker substudy: 1-hour reduction in anti-FXa (OR 0.69/100 ng/mL) and rise in ETP (OR 0.94/100 nmol/L-min) both predict fewer hematoma expansions; the ETP rise also independently predicts more thrombotic events (OR 1.08).
Post-hoc analysis of MR CLEAN-MED + MR CLEAN-NO IV: perforator-territory infarcts after LVO thrombectomy (n=397) triple the odds of worse 90-day mRS without affecting 24-h NIHSS.
MR CLEAN Registry M2 analysis (n=539): bridging IV thrombolysis before EVT improves 90-day mRS vs direct EVT (aOR 1.52, P=0.03); sICH and recanalization similar.
ETLAS-2 phase II: tadalafil 20 mg daily for 3 months in CSVD fails feasibility (compliance 68% vs 94% placebo) with 2-fold more AEs; per-protocol WMH volume trend suggests mechanistic signal at lower doses.
OPTIMAS subgroup analysis: in 3,619 stroke patients with AF, neither the time of AF diagnosis nor AF subtype modifies the effect of early DOAC initiation versus delayed initiation.
ZODIAC phase III RCT (n=92, stopped early for efficacy): 0° vs 30° head-of-bed positioning before thrombectomy — END HR 34.40 (95% CI 4.65–254.37), P<0.001; exploratory mortality P=0.03.
T-FLAVOR Japanese phase 2 (n=218): tenecteplase vs low-dose alteplase for LVO bridging — substantial reperfusion 10.3% vs 3.6% (90% CI 0.89–12.1; 95% CI −0.19% to 13.2%; mRS shift favors TNK numerically).
