Summary
Multicenter, randomized, placebo-controlled, double blind, phase 2b trial of acute stroke patients treated with mechanical thrombectomy (MT), in which two therapies are compared: rt-PA or placebo. Allocation at each center will account for 1 stratum: use of alteplase (yes vs. no) before MT. Subjects will be followed up to 90 days post-randomization.

Outcome
Met primary endpoint
paper 59.0% (36/61) with alteplase and 40.4% (21/52) with placebo (adjusted risk difference, 18.4%; 95% CI, 0.3%-36.4%; P = .047). PMID 35143603 ↗
paper the use of adjunct intra-arterial alteplase compared with placebo resulted in a greater likelihood of excellent neurological outcome at 90 days. PMID 35143603 ↗
