Brief summary
The purpose of the study is to evaluate whether desmoteplase is safe and tolerated when given to Japanese patients with acute ischemic stroke
Detailed description
The study is a safety and tolerability study of desmoteplase in Japanese patients with acute ischemic stroke. The study will test two doses
Interventions

1 bolus injection of placebo IV

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the safety and tolerability of desmoteplase doses of 70 µg/kg and 90 µg/kg in Japanese patients with acute ischemic stroke as measured by the presence of symptomatic intracranial haemorrhage (sICH) within 72 hours after IMP | 90 days |
Secondary
| Measure | Time frame |
|---|---|
| To explore the predictive value of different volumes of absolute mismatch for the clinical response and other objectives | Day 90 |
| To evaluate the clinical improvement at Day 90 after administration of Investigational Medicinal Product (IMP) as measured by modified Rankin Scale (mRS) | 90 days |
| To evaluate the clinical improvement at Day 7 and 30 after administration of IMP as measured by modified Rankin Scale (mRS) | Day 7 and Day 30 |
| To evaluate the immunogenicity of desmoteplase | Day 7, Day 30, Day 90 |
| To evaluate change in infarct size at 18±6 hr relative to pre-treatment infarct size | 18±6 hr after administration |
| To evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of desmoteplase | 0.5 - 9 hr |
| To evaluate recanalisation at 18±6 hr after administration of IMP | 18±6 hr after administration of IMP |
