Daiichi Sankyo Announces Phase 3 Study Results for Prasugrel Antiplatelet Agent in Thrombotic Stroke Patients
Tokyo, Japan (July 21, 2020) - Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) today announced the achievement of the primary endpoint in the Japan PRASTRO-III phase 3 study (hereafter, the study) of the antiplatelet agent, prasugrel hydrochloride (hereafter, prasugrel), in thrombotic stroke patients.
The study was carried out in a double-blind comparative manner to examine the efficacy and safety of prasugrel and clopidogrel in 234 thrombotic stroke patients with one or more risk factors for the recurrence of ischemic stroke.
The incidence of cerebral cardiovascular events (such as ischemic stroke, myocardial infarction, and other vascular deaths) was lower in the prasugrel group than in the clopidogrel group, thus achieving the primary endpoint in the study. Furthermore, no additional safety concerns were identified.
The results of the study will be announced in detail through future academic conferences and publications.
Daiichi Sankyo will continue efforts to provide new treatment options for thrombotic stroke patients.
Although ischemic stroke is caused by various conditions, thrombotic stroke is characterized by occlusion of cerebral blood vessels by platelet thrombi mainly due to arteriosclerosis.
