TEMPO-2 Clinical Trial

TEMPO-2 is a  randomized controlled trial of TNK‐tPA versus standard of care for minor ischemic stroke proven minor ischemic stroke with proven occlusion. 

Study Inclusion Criteria:

1. Acute ischemic stroke in an adult patient (18 years of age or older)

2. Onset (last-­‐seen-­‐well) time to treatment time ≤ 12 hours.

3. TIA or minor stroke defined as a baseline NIHSS ≤ 5 at the time of randomization. Patients do not have to have persistent demonstrable neurological deficit on physical neurological examination.

4. Any acute intracranial occlusion or near occlusion (TICI 0 or 1) (MCA, ACA, PCA, VB territories) defined by non-­‐invasive acute imaging (CT angiography or MR angiography) that is neurologically relevant to the presenting symptoms and signs. An acute occlusion is defined as TICI 0 or TICI 1 flow.1 Practically this can include a small amount of forward flow in the presence of a near occlusion AND; Delayed washout of contrast with pial vessels on multiphase CTA in a region of brain concordant with clinical symptoms and signs OR, Any area of focal perfusion abnormality identified using CT or MR perfusion – e.g. transit delay (TTP, MTT or TMax), in a region of brain concordant with clinical symptoms and signs.

5. Pre-­‐stroke independent functional status – mRS ≤ 2. 6. Informed consent from the patient or surrogate.

6. Patients can be treated within 90 minutes of the first slice of CT (or MRI)
