A Phase III, Prospective, Double-blind, Randomized, Placebo-controlled Trial of Thrombolysis in Imaging-eligible, Late-window Patients to Assess the Efficacy and Safety of Tenecteplase (TIMELESS)
In Brief
A Phase 3 clinical trial evaluating Tenecteplase and Placebo for THROMBOLYSIS. Completed, enrolled 458 participants across 97 sites in 2 countries.
Detailed Summary
This study will evaluate the efficacy and safety of tenecteplase compared with placebo in participants with acute ischemic stroke (AIS). All participants will receive standard-of-care therapy according to AmericanHeart Association/American Stroke Association clinical guidelines (2018). To determine eligibility for randomization, all participants will undergo multimodal CT or MRI at baseline. Only participants with a vessel occlusion (ICA or MCA M1/M2) and penumbral tissue will be randomized. The primary analysis is to compare the efficacy of tenecteplase versus placebo in all participants at Day 90.
Study Details
Timeline
Interventions
The investigational medicinal product (IMP) for this study is tenecteplase. The recommended total dose for this study is weight-based with 0.25 mg of tenecteplase per kg, not exceeding a maximum dose of 25 mg. A single bolus dose should be administered over 5 seconds based on patient weight.
Placebo is being used as the comparator since a thrombolytic is only FDA-approved in the United States for use out to 3 hours, and the standard of care guidelines support use out to 4.5 hours.
