Summary

The Tenecteplase Treatment in Acute Ischemic Stroke (TETRIS) Registry is multicenter ambispective observational study of patients with acute ischemic stroke who received intravenous thrombolysis with Tenecteplase

Detailed description

Acute ischemic stroke management has considerably evolved over the last 20 years with the development of reperfusion treatments: intravenous thrombolysis (IVT) with alteplase, which is effective for AIS within 4.5 hours from symptoms onset and up to 9 hours in some cases; and mechanical thrombectomy (MT), in AIS with large vessel occlusion (LVO) within 24 hours from symptoms onset, either after IVT (bridging therapy) or alone in case of IVT contra-indication. Alteplase is a recombinant form of tissue plasminogen activator (rtPA) that, when bound to fibrin, will activate plasminogen and lead to fibrinolysis and clot dissolution. It is administered at a dose of 0.9 mg/kg (maximum 90 mg) with an intravenous bolus (10% of the dose) followed by a one-hour infusion. Tenecteplase is a genetically modified form of alteplase with greater fibrin specificity and a longer half-life, which allows a simpler one bolus administration at a dose of 0.25 mg/kg (maximum 25 mg). In the Tenecteplase versus Alteplase before Endovascular Therapy for Ischemic Stroke (EXTEND-IA TNK) randomized clinical trial, which compared tenecteplase and alteplase in bridging therapy for AIS with LVO, tenecteplase achieved a better recanalization rate on arteriography before MT and a better functional outcome at 3 months. Following this trial, tenecteplase was added in stroke guidelines as an alternative to alteplase for IVT in bridging therapy. More recently, the Alteplase compared to Tenecteplase (ACT) trial has shown, in patients with LVO and non-LVO AIS, that tenecteplase is non-inferior to alteplase in terms of functional outcome. It is likely that in the near future tenecteplase will be added as an alternative to alteplase for AIS without LVO. However, while some "real-life" studies have been published on tenecteplase use for AIS with LVO, data on the general use of tenecteplase are still scarce. The Tenecteplase Treatment in Acute Ischemic Stroke (TETRIS) Registry is multicenter ambispective observational study of patients with acute ischemic stroke who received intravenous thrombolysis with Tenecteplase. The main aim of this registry is to provide routine clinical care data on the use of tenecteplase for IVT for both AIS with and without LVO, in order to further characterize the safety and efficacy of tenecteplase for AIS. Additionally, we aim to use this registry which combines clinical and radiological data to explore other aspects related to AIS management in this cohort.
