Outcome Measures
Primary Outcomes (1)
Summary of Treatment-Emergent Adverse Event Reported by >10% of Participants Following Ascending Doses of DS-1040b and a Placebo in Participants With Acute Ischemic Stroke
Treatment-emergent adverse event (TEAE) is defined as an adverse event that emerges during the treatment period (from first dose date until 30 days after the last dosing date), having been absent at predose; or reemerges during treatment, having been present at baseline but stopped prior to treatment; or worsens in severity after starting treatment relative to the pre-dose state, when the adverse event is continuous.
Baseline up to 90 days post last dose, up to 3 years 11 months
Secondary Outcomes (6)
Summary of Pharmacokinetic (PK) Parameter Maximum (Peak) Observed Plasma Concentration (Cmax) of DS-1040b Following Ascending Doses in Participants With Acute Ischemic Stroke
Predose, 0.5, 3, 6, 9, 12, 24, 48, 72, and 96 hours postdose
Summary of Pharmacokinetic Parameter Area Under the Concentration Versus Time Curve From Zero to Last Quantifiable Concentration Sampling Point (AUClast) of DS-1040b Following Ascending Doses in Participants With Acute Ischemic Stroke
Predose, 0.5, 3, 6, 9, 12, 24, 48, 72, and 96 hours postdose
Summary of Pharmacokinetic Parameter Terminal Half-life (t1/2) of DS-1040b Following Ascending Doses in Participants With Acute Ischemic Stroke
Pre-dose, 0.5, 3, 6, 9, 12, 24, 48, 72, and 96 hours post-dose

Eligibility Criteria
You may qualify if:
- Has a clinical diagnosis of acute ischemic stroke (including lacunar stroke/infarct) supported by computed topography or magnetic resonance imaging to rule out alternative cause for presenting symptoms
- Has onset of stroke symptoms within 4.5 to 12 hours before initiation of study drug administration - for subjects with a stroke upon waking, time of symptom onset is the last time the subject was known to be well
- Has a NIHSS score of ≥ 2 (for Cohorts 1-5) and ≥ 5 (for Cohort 6)
- Has Low dose heparin or low molecular weight heparin at a preventive dose are allowed from 24 hours after treatment start completion and after confirmation of no intracranial bleeding on the 24-hours repeat brain imaging.
- Is a Cohort 6 participant who is treated or anticipated to be treated with intra-arterial therapy (IAT) for ischemic stroke at the time of randomization (for enrollment in the IAT subgroup)
- Has given written informed consent to participate in the study prior to participating in any study-related procedures - depending on country-specific practice, written informed consent may be acceptable from legally authorized representative
- Has given a separate written informed consent for collecting a blood sample for genotyping
You may not qualify if:
- Is a Cohort 1-5 participant who has been treated or is going to be treated with tissue plasminogen activator (tPA) and/or endovascular thrombectomy during current stroke
- Is a Cohort 6 participant treated or anticipated to be treated with tPA during current stroke
- Has evidence of intracranial hemorrhage on non-contrast computed tomography (CT/CAT) scan or magnetic resonance imaging (MRI)
- Has symptoms of subarachnoid hemorrhage, even with normal imaging
- Has an Alberta Stroke Program Early CT Score (ASPECTS) \<6
- Has prior non-traumatic intracranial hemorrhage (excluding microhemorrhages observed in imaging)
- Has known arteriovenous malformation or aneurysm
- Has evidence of active bleeding
- Has platelet count less than 100,000
- Has International Normalized Ratio greater than 1.7
- Has used unfractionated heparin within 24 hours prior to treatment and has an elevated partial thromboplastin time
- Has used a non-vitamin K antagonist oral anticoagulant such as dabigatran, rivaroxaban, apixaban, or other factor Xa inhibitors within 24 hours before treatment
- Has used fondaparinux or low molecular weight heparin at an anticoagulation dose within 24 hours prior to treatment
- Has anticipated use of an anticoagulation dose of heparin, or fondaparinux or low molecular weight heparin, or nonvitamin K antagonist oral anticoagulant such as dabigatran, rivaroxaban, apixaban, or other factor Xa inhibitors within 48 hours after completion of study drug treatment (low dose heparin or low molecular weight heparin at a preventive dose are allowed from 24 hours after treatment completion and after confirmation of no intracranial bleeding on the 24 hours repeat brain imaging. In Cohort 6, heparin treatment associated with IAT is allowed.)
- Has blood pressure \> 185/110 mmHg, or requires aggressive medication to maintain blood pressure below this limit (routine medical treatment including IV drug treatment is allowed to lower the blood pressure below this limit)
