Clinical Trial Summary

TENecteplase in Central Retinal Artery Occlusion (TenCRAOS): A Prospective, randomized-controlled, double-dummy, double-blind phase 3 multi-centre trial of TNK 0.25 mg/kg + placebo vs. ASA + placebo (2 arms with 1:1 block randomization).

A Prospective, randomized-controlled, double-dummy, double-blind phase 3 multi-centre trial of TNK 0.25 mg/kg + placebo vs. ASA + placebo (2 arms with 1:1 block randomization). At all participating centers, ophthalmologists are involved in the diagnosis and visual outcome measurements using a standardized protocol. The patients will be promptly examined by the ophthalmologist. As soon as the CRAO is diagnosed by the ophthalmologist, the patients will be managed in the stroke unit during treatment, monitoring, and medical investigations. After treatment in the stroke unit, the patients will be re-examined by an ophthalmologist and a neurologist as an out-patient at (30 ±5) and 90 (±15) days

Clinical Trial Description

Central retinal artery occlusion (CRAO) is an ophthalmologic emergency that, without prompt revascularization, bears high risk of permanent blindness. The condition is typically the result of an artery-to-artery embolism from a carotid plaque or cardio embolism. A recent meta-analysis of observational data indicates that prompt revascularization with systemic thrombolysis might improve outcome. A randomized controlled trial of early systemic thrombolysis for CRAO is therefore warranted. The aim of this project is to assess the effect of systemic tissue plasminogen activator tenecteplase versus placebo administered within 4.5 hours of CRAO onset in patients admitted to the participating hospitals in Europe. The main endpoint is the proportion of patients with ≤ 0.7 logMAR visual acuity 30 (±5) days after treatment, representing an improvement in visual acuity of at least 0.3 logMAR, equal to at least 15 letters/three lines on a visual acuity chart. In addition, we will access differences in visual field parameters and patient reported outcome measures between the groups. This study is based on a broad collaboration and interaction between leading ophthalmologists and neurologists in European centres. ;
