What does this research mean for the field?

In a murine stable arterial thrombosis model, cangrelor and GR 144053 induce complete thrombus disaggregation, while heparin and rtPA induce destabilization, and aspirin, UFH, or hirudin show no effect on pre-formed thrombi.

Key result

Cangrelor achieves complete thrombus disaggregation and vessel recanalization in a murine thrombosis model.

P=0.002

Why the study?

Existing arterial thrombosis models are limited by biphasic thrombus dynamics, which prevents assessing thrombus destabilization, disaggregation, or thrombolysis after pharmacological treatment.

Comparison

Various antithrombotic agents administered 15 min after initiation of thrombosis

Design

Implication

Extends antithrombotic testing to preformed stable thrombi in mice; leaves open translation to human arterial thrombosis.

Does post-onset administration of antithrombotic agents disaggregate or destabilize a pre-formed stable thrombus in a murine FeCl3-induced carotid artery thrombosis model?

Population

C57BL6-J mice aged 7-10 weeks were used to develop and validate a stable arterial thrombosis model using FeCl3 injury on the carotid artery.

Intervention

Intravenous injection of antithrombotic agents 15 minutes after initiation of thrombosis, including Cangrelor (1 mg/kg), GR 144053 trihydrochloride (10 mg/kg), heparin (50 IU/kg), rtPA (10 mg/kg), TNK (10 mg/kg), aspirin (8 mg/kg), UFH (100 IU/kg), or hirudin (10 mg/kg).

Comparator

Intravenous injection of saline 15 minutes after initiation of thrombosis.

Outcome

Thrombus area and flow dynamics (disaggregation or destabilization) measured by intravital fluorescence microscopy and Doppler probe over 45 minutes.surrogate

Main Result

p-value: p=0.002

A novel 2-spot FeCl3-induced murine stable thrombosis model successfully allows for the evaluation of the curative effects of antithrombotic and thrombolytic agents on preformed arterial thrombi.

Limitations

Interspecies differences between mice and humans in platelet biology and coagulation may influence translational relevance.
Absence of exposure of subendothelial matrix proteins may underestimate mechanisms driven by vascular wall injury.
The thrombin-dependent nature of the model could bias responses toward therapies targeting thrombin generation or activity.
Relatively short observation period (30 minutes) after drug administration precludes investigation of long-term thrombus remodeling.
Did not evaluate the impact of embolization resulting from vessel recanalization.

Fauth et al. (2026) studied Arterial thrombosis. Antithrombotic agents (Cangrelor, GR 144053 trihydrochloride) vs. Saline was evaluated on Thrombus area (Area Under the Curve) (p=0.002). In a novel murine stable thrombosis model, administration of cangrelor or GR 144053 trihydrochloride 15 minutes after injury induced complete thrombus disaggregation and vessel recanalization.
