Patients who meet inclusion criteria with anterior circulation LVO stroke and successful reperfusion will be randomised to receive IA tenecteplase or best medical management at 1:1 ratio.Results The primary endpoint is a 90-day excellent outcome defined as modified Rankin Scale (mRS) 0–1. The primary safety endpoint is symptomatic intracranial haemorrhage within 48 hours from randomisation. Secondary endpoints include 90-day ordinal mRS, mRS 0–2, mRS 0–3, all-cause mortality and any intracranial haemorrhage.Conclusion In patients with anterior circulation LVO stroke, the ANGEL-TNK trial will inform whether adjunct IA tenecteplase administered after successful thrombectomy reperfusion improves patient outcomes.Trial registration number NCT05624190.Data are available upon reasonable request.
