Key result

Blocking the EP3 receptor with DG-041 reduced platelet aggregation without significantly altering cutaneous bleeding time in healthy patients, and inhibited atherothrombosis in mice.

Why the study?

Does DG-041 reduce thrombosis without impairing haemostasis in murine models and healthy patients?

Population

Murine models of thrombosis and atherosclerosis, human atherosclerotic plaques and blood, and healthy human…

Overview

EP3 blockade may enable antithrombotic effects without bleeding liability; leaves open confirmation in cardiovascular patients.

Structured PICO

Does DG-041 reduce thrombosis without impairing haemostasis in murine models and healthy patients?

P
Population
Murine models of thrombosis and atherosclerosis, human atherosclerotic plaques and blood, and healthy human patients
I
Intervention
DG-041 (EP3 receptor blocking agent)
O
Outcome
Thrombosis (murine models) and platelet aggregation (human)surrogate

Blocking the EP3 receptor with DG-041 reduces thrombosis and enhances clopidogrel efficacy without increasing bleeding risk in preclinical models and healthy volunteers.

Cite This Study

Tilly et al. (2013) studied Healthy volunteers and murine models. DG-041 was evaluated on Platelet aggregation and cutaneous bleeding time. Blocking the EP3 receptor with DG-041 reduced platelet aggregation without significantly altering cutaneous bleeding time in healthy patients, and inhibited atherothrombosis in mice.
