In acute ischemic stroke
Activase (Alteplase) makes a positive
clinical difference*
See how Activase (t-PA) may reverse neurologic impairment*
This hypothetical representation of 16 patients treated with Activase (t-PA) vs 16 patients treated with placebo is based on NINDS results at 3 months.1
In this illustration, 1 of the mortalities in the Activase (t-PA) group could be due to SICH.
Patients treated with Activase (t-PA)
Patients treated with placebo
Patients with symptomatic intracranial hemorrhage (SICH)†
- Outcomes reflect data reported in Figure 2 of Part 2 of the NINDS study, applied to this hypothetical patient population1
- Assignment to disability levels is based on average percentage per group on all 4 assessment scales (NIHSS, Barthel Index, Modified Rankin Scale, and Glasgow Outcome Scale)
NINDS study design: The National Institute of Neurological Disorders and Stroke (NINDS) rt-PA Stroke Study was a randomized, double-blind, placebo-controlled study of patients with acute ischemic stroke treated with intravenous recombinant tissue plasminogen activator (t-PA) or placebo. At 3 months (N=333), a global test statistic was used to assess clinical outcomes. Favorable outcome was defined as NIHSS, <1; Barthel Index, 95 or 100; Modified Rankin Scale, 0 or 1; and Glasgow Outcome Scale, 1.
In NINDS, when eligible patients were treated with Activase (t-PA) compared with placebo1:
- More stroke victims sustained minimal to no disability (31% vs 20%†)
- Fewer had moderate-to-severe disability (52% vs 59%†)
- There was no statistically significant difference in overall mortality (17% vs 21%; P=0.30)
- Approximately half of patients experiencing SICH had nonfatal outcomes at 36 hours
- – 55% (11 of 20) of patients treated with Activase (t-PA) and 50% (1 of 2) of patients given a placebo
- – The rate of SICH among patients treated with Activase (t-PA) was 6.4% vs 0.6% with placebo (P<0.001) at 36 hours
