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

Condition or disease Intervention/treatment Phase
Acute Ischemic Stroke Drug: Desmoteplase Other: Placebo Phase 2

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

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 48 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Randomised, Double-blind, Placebo-controlled, Dose-escalation Study of Desmoteplase in Japanese Patients With Acute Ischemic Stroke
Study Start Date : August 2010
Actual Primary Completion Date : August 2013

Arm Intervention/treatment
Experimental: Desmoteplase 70 µg/kg Drug: Desmoteplase
1 bolus injection of desmoteplase 70 µg/kg intravenous (IV)

Experimental: Desmoteplase 90 µg/kg Drug: Desmoteplase
1 bolus injection of desmoteplase 90 µg/kg (IV)

Placebo Comparator: Placebo Other: Placebo
1 bolus injection of placebo IV

Primary Outcome Measures :
  1. 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 [ Time Frame: 90 days ]

Secondary Outcome Measures :
  1. To evaluate the clinical improvement at Day 90 after administration of Investigational Medicinal Product (IMP) as measured by modified Rankin Scale (mRS) [ Time Frame: 90 days ]
  2. To evaluate the clinical improvement at Day 7 and 30 after administration of IMP as measured by modified Rankin Scale (mRS) [ Time Frame: Day 7 and Day 30 ]
  3. To evaluate recanalisation at 18±6 hr after administration of IMP [ Time Frame: 18±6 hr after administration of IMP ]
  4. To evaluate change in infarct size at 18±6 hr relative to pre-treatment infarct size [ Time Frame: 18±6 hr after administration ]
  5. To evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of desmoteplase [ Time Frame: 0.5 - 9 hr ]
  6. To evaluate the immunogenicity of desmoteplase [ Time Frame: Day 7, Day 30, Day 90 ]
  7. To explore the predictive value of different volumes of absolute mismatch for the clinical response and other objectives [ Time Frame: Day 90 ]
