Outcomes
Primary outcome [1] 0 0
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
Assessment method [1] 0 0
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.

Assessment method [1] 0 0
The PK parameter of Maximum (Peak) Observed Plasma Concentration (Cmax) of DS-1040b was calculated from the plasma concentrations of DS-1040b using non-compartmental analysis

Assessment method [2] 0 0
The PK parameter of Area Under the Concentration Versus Time Curve from Zero to Last Quantifiable Concentration Sampling Point of DS-1040b was calculated from the plasma concentrations of DS-1040b using non-compartmental analysis

Assessment method [3] 0 0
The PK parameter of Terminal Half-life of DS-1040b was calculated from the plasma concentrations of DS-1040b using non-compartmental analysis in patients with available sample for the analysis.
Timepoint [3] 0 0
Pre-dose, 0.5, 3, 6, 9, 12, 24, 48, 72, and 96 hours post-dose

The enzymatic activity of thrombin-activatable fibrinolysis inhibitor was assessed using the Stago Coagulation Analyzer.
Timepoint [4] 0 0
Baseline and 6 hours postdose
Secondary outcome [5] 0 0
Summary of Changes From Baseline at Day 30 in National Institute of Health Stroke Scale (NIHSS) Score Following Ascending Doses of DS-1040b and a Placebo in Participants With Acute Ischemic Stroke
Assessment method [5] 0 0
The National Institute of Health Stroke Scale (NIHSS) quantifies stroke severity based on weighted evaluation findings. The score for each ability is a number between 0 and 4, with 0 being normal functioning and 4 being completely impaired. The patient's NIHSS score is calculated by adding the number for each element of the scale; 42 is the highest score possible. In the NIHSS, the higher the score indicates more impairment (worse outcome) in a stroke patient.
Timepoint [5] 0 0
30 days post dose
Secondary outcome [6] 0 0
Percentage of Participants With a Modified Rankin Scale (mRS) Score of 0 to 2 Following Ascending Doses of DS-1040b and a Placebo in Participants With Acute Ischemic Stroke
Assessment method [6] 0 0
The modified Rankin scale (mRS) is a commonly used disability scale derived from the Rankin scale that is used to measure the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. The level of disability following a stroke is assessed via a scale from 0 to 6, where 0 is no symptoms at all and 6 indicates death. Higher scores indicate worse outcome. The percentage of participants with an mRS score of 0 to 2 at Day 5 (baseline) and Day 90 is being reported.
Timepoint [6] 0 0
Day 5 (baseline) and Day 90 post dose
