Stroke Clinical Trials

The Functional Improvement and Recovery after STROKE Trial: The FIRST Trial is a Prospective, single-arm, multi-center study to determine the natural history of acute ischemic stroke from large vessel thrombo-embolism in the brain. Patient’s who present within 8 hours from stroke symptom onset with a NIH Stroke Scale (NIHSS) score >10 and who are ineligible for IV-rtpa or endovascular therapy will be considered for the study. The functional outcomes as defined by the modified Rankin Scale (mRS) of all enrolled patients will be followed for 90 days after the index event. The study has been reviewed by the centralized North Texas Division IRB at the Medical City of Dallas Hospital as well as IRB at The Medical Center of Plano.
