BACKGROUND: Intravenous thrombolysis is a standard treatment of acute ischemic stroke. The efficacy and safety of combining intravenous thrombolysis with argatroban (an anticoagulant agent) or eptifibatide (an antiplatelet agent) are unclear.
METHODS: We conducted a phase 3, three-group, adaptive, single-blind, randomized, controlled clinical trial at 57 sites in the United States. Patients with acute ischemic stroke who had received intravenous thrombolysis within 3 hours after symptom onset were assigned to receive intravenous argatroban, eptifibatide, or placebo within 75 minutes after the initiation of thrombolysis. The primary efficacy outcome, the utility-weighted 90-day modified Rankin scale score (range, 0 to 10, with higher scores reflecting better outcomes), was assessed by means of centralized adjudication. The primary safety outcome was symptomatic intracranial hemorrhage within 36 hours after randomization.
RESULTS: A total of 514 patients were assigned to receive argatroban (59 patients), eptifibatide (227 patients), or placebo (228 patients). All the patients received intravenous thrombolysis (70% received alteplase, and 30% received tenecteplase), and 225 patients (44%) underwent endovascular thrombectomy. At 90 days, the mean (±SD) utility-weighted modified Rankin scale scores were 5.2±3.7 with argatroban, 6.3±3.2 with eptifibatide, and 6.8±3.0 with placebo. The posterior probability that argatroban was better than placebo was 0.002 (posterior mean difference in utility-weighted modified Rankin scale score, -1.51±0.51) and that eptifibatide was better than placebo was 0.041 (posterior mean difference, -0.50±0.29). The incidence of symptomatic intracranial hemorrhage was similar in the three groups (4% with argatroban, 3% with eptifibatide, and 2% with placebo). Mortality at 90 days was higher in the argatroban group (24%) and the eptifibatide group (12%) than in the placebo group (8%).
CONCLUSIONS: In patients with acute ischemic stroke treated with intravenous thrombolysis within 3 hours after symptom onset, adjunctive treatment with intravenous argatroban or eptifibatide did not reduce poststroke disability and was associated with increased mortality.
