Clinical Study of Desmoteplase in Japanese Patients With Acute Ischemic Stroke (DIAS-J)

This study has been completed.
Information provided by (Responsible Party):
Lundbeck Japan K. K. Identifier:
First received: April 8, 2010
Last updated: October 14, 2015
Last verified: October 2015
The purpose of the study is to evaluate whether desmoteplase is safe and tolerated when given to Japanese patients with acute ischemic stroke

Condition Intervention Phase
Acute Ischemic Stroke Drug: Desmoteplase Other: Placebo Phase 2

Study Type: Interventional
Study Design: 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

Further study details as provided by Lundbeck Japan K. K.:

Primary Outcome Measures:
  • 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:
  • 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 ]
  • 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 ]
  • To evaluate recanalisation at 18±6 hr after administration of IMP [ Time Frame: 18±6 hr after administration of IMP ]
  • To evaluate change in infarct size at 18±6 hr relative to pre-treatment infarct size [ Time Frame: 18±6 hr after administration ]
  • To evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of desmoteplase [ Time Frame: 0.5 - 9 hr ]
  • To evaluate the immunogenicity of desmoteplase [ Time Frame: Day 7, Day 30, Day 90 ]
  • To explore the predictive value of different volumes of absolute mismatch for the clinical response and other objectives [ Time Frame: Day 90 ]

Enrollment: 48
