Endpoints
Safety parameters will include; adverse events occurrence,
physical examination findings, vital sign measurements,
standard clinical laboratory parameters (including serum
chemistry, hematology, urinalysis, and coagulation
parameters), and electrocardiogram (ECG) parameters.
Other safety parameters will include bleeding events and
neurologic function. Bleeding events will be assessed and
categorized as symptomatic intracranial hemorrhage
(sICH), any intracranial hemorrhage (ICH), or non-ICH
major bleeding. Neurologic function will be measured
using the NIHSS.
Pharmacokinetic Parameters:
The PK parameters that will be calculated from the plasma
concentrations of DS-1040a using non-compartmental
analysis are the area under the concentration-versus-time
curve, from time 0 to the last quantifiable concentration
sampling point (AUClast), maximum (peak) observed
plasma concentration (Cmax), and time of maximum
observed concentration (tmax). If data permit, the following
parameters will be estimated: the area under the
concentration-versus-time curve from time 0 extrapolated
to infinity (AUC0-inf), half-life (t1/2), clearance, and the
volume of distribution at terminal elimination phase.
The PK parameters that will be calculated from urinary
concentrations of DS-1040a are the amount of drug
excreted in urine from 0 to 24 hours (Ae0-24), the renal
clearance (CLR), and the percentage of the dose
administered excreted in urine from 0 to 24 hours
(%Fe0-24).
Pharmacodynamic Parameters:
Pharmacodynamic analysis for thrombin-activatable
fibrinolysis inhibitor (TAFI) antigen, clot lysis (an
exploratory biomarker), D-dimer, and total TAFIa activity
will be performed. Remaining blood samples will be used
for post-hoc TAFIa inhibition-related coagulation
biomarker assessments.
Recanalization will be assessed by CT (or MR)
angiography at predose baseline and 24 hours after the start
of treatment using modified Arterial Occlusive Lesion
(mAOL) scores in the subjects with visible occlusion at
predose.
Functional Outcome Parameter:
Functional outcome will be assessed using mRS.
Inclution Criteria
included in the study:
1. Men and women 18 years of age and older.
2. Subjects have a clinical diagnosis of acute ischemic
stroke (including lacunar stroke) supported by
computed topography or magnetic resonance
imaging.
3. Subjects have stroke symptoms onset within 4.5 to
12 hours before initiation of study drug
administration. For subjects with a wake-up stroke,
symptoms onset time refers to the last time the
subject was known to be well.
4. Subjects have a NIHSS score of ≥ 2.
5. Subjects (or their legally authorized representativewhere applicable and based on country-specific
practice), must give written informed consent to
participate in the study prior to participating in any
study-related procedures. A separate written
informed consent is required for collecting a blood
sample for genotyping.
Exclusion Criteria
disqualified from entering the study:
1. Subjects have been treated or are anticipated to be
treated with tissue plasminogen activator and/or
endovascular thrombectomy during current stroke.
Eligible subjects declining these treatments can be
enrolled to this study.
2. Subjects have evidence of intracranial hemorrhage
on non-contrast computed tomography (CT) (or
magnetic resonance [MR]).
3. Subjects have symptoms of subarachnoid
hemorrhage, even with normal CT.
4. Subjects have an Alberta Stroke Program Early CT
Score (ASPECTS) <6.
5. Subjects have prior non-traumatic intracranial
hemorrhage (excluding microhemorrahages
observed in imaging).
6. Subjects have known arteriovenous malformation or
aneurysm.
7. Subjects have evidence of active bleeding.
8. Subjects have platelet count < 100,000.
9. Subjects have International Normalized Ratio > 1.7.
10. Subjects have used unfractionated heparin within 24
hours prior to treatment and have an elevated partial
thromboplastin time.
11. Subjects have used a nonvitamin K antagonist oral
anticoagulant such as dabigatran, rivaroxaban,
apixaban, or other factor Xa inhibitors within
24 hours prior to treatment.
12. Subjects have used fondaparinux or low molecular
weight heparin at an anticoagulation dose within
24 hours prior to treatment.
13. Subjects with 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 of randomization. Low dose heparin or low
molecular weight heparin at a preventive dose are
allowed from 24 hours after treatment start and after
confirmation of no intracranial bleeding on the
24-hours repeat brain imaging.
14. Subjects have blood pressure > 185/110 mmHg, or
require aggressive medication to maintain blood
pressure below this limit (routine medical treatment
is allowed to lower the blood pressure below this
limit).
15. Subjects have had intracranial surgery, clinically
significant head trauma (in the opinion of Principal
Investigator), Alteplase treatment, or a previous
stroke within 1 month.
16. Subjects have had major surgery within 14 days.
17. Subjects have had gastrointestinal or genitourinary
bleeding in the last 21 days.
18. Subjects have had a lumbar puncture (or epidural
steroid injection) within 14 days.
19. Subjects have a preexisting disability classified by
mRS > 2.
20. Subjects have an estimated glomerular filtration rate
(using Modification of Diet in Renal Disease
equation) < 60 mL/min/1.73 m2
.
21. Subjects have baseline hemoglobin < 10.5 g/dL.
22. Subjects have a positive pregnancy test. Serum or
urine pregnancy tests will be performed (according
to site-specific practice) in women of childbearing
potential (childbearing potential is assumed in
women up to 55 years of age).
23. Subject is currently participating in another
investigational study or has participated in an
investigational drug study within 30 days or
5 half-lives of that investigational drug prior to
administration of the study drug.
24. Subject is an employee or an immediate family
member of an employee of the Sponsor, the CRO
(INC Research), or the Site.
25. Any other reason, in the opinion of the Investigator,
which precludes subject participation in the study.
