a multicentre, prospective, randomised, open-label, blinded-endpoint, superiority, phase 3 trial

Yunyun Xiong, Fana Alemseged, Zhixin Cao et al. - The Lancet

The TRACE-5 trial demonstrated that intravenous tenecteplase within 24 hours improved functional outcomes in Chinese patients with ischemic stroke due to basilar artery occlusion. The results support thrombolysis as an effective treatment for this devastating posterior circulation stroke subtype.

Summary

In this trial involving Chinese patients with ischaemic stroke due to basilar artery occlusion, tenecteplase within 24 h after stroke onset improved functional outcome compared with standard medical treatment. The incidence of symptomatic intracranial haemorrhage and death was similar.
