Please assess the completion status of the following clinical trial:

Trial Title: Endovascular Treatment for Small Core and Proximal Occlusion Ischemic Stroke

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria A. Clinical (Heterogeneous sampling frame)~1. Acute ischemic stroke~2. Age 18 or greater~3. Onset (last-seen-well) time to randomization time \< 12 hours.~4. Disabling stroke defined as a baseline NIHSS \> 5 at the time of randomization.~5. Pre-stroke (24 hours prior to stroke onset) independent functional status in activities of daily living with modified Barthel Index \> 90. Patient must be living in their own home, apartment or seniors lodge where no nursing care is required.~   B. Imaging (Homogeneous target population)~6. Confirmed symptomatic intracranial occlusion, based on single phase, multiphase or dynamic CTA, at one or more of the following locations: Carotid T/L, M1 MCA, or M1-MCA equivalent (2 or more M2-MCAs). Anterior temporal artery is not considered an M2.~7. Non-contrast CT and CTA for trial eligibility performed or repeated at ESCAPE stroke center with endovascular suite on-site.~8. Endovascular treatment intended to be initiated (groin puncture) within 60 minutes of baseline non-contrast CT with target baseline non-contrast CT to first recanalization of 90 minutes.~9. Signed informed consent or appropriate signed deferral of consent where approved.~Exclusion Criteria~1. Baseline non-contrast CT reveals a moderate/large core defined as extensive early ischemic changes of ASPECTS 0-5 in the territory of symptomatic intracranial occlusion.~2. Other confirmation of a moderate to large core defined one of three ways:~   1. On a single phase, multiphase or dynamic CTA: no or minimal collaterals in a region greater than 50% of the MCA territory when compared to pial filling on the contralateral side (multiphase/dynamic CTA preferred) OR~  2. On CT perfusion (\>8 cm coverage): a low CBV and very low CBF ASPECTS \<6 AND in the symptomatic MCA territory OR~  3. On CT perfusion(\<8 cm coverage): a region of low CBV and very low CBF \>1/3 of the CTP imaged symptomatic MCA territory.~3. Groin puncture is not possible within 60 minutes of the first slice of non-contrast CT acquisition (please note that if CTP is performed it should be done after CTA).~4. No femoral pulses or very difficult endovascular access that will result in a non-contrast CT-to-recanalization time that is longer than 90 minutes, or will result in an inability to deliver endovascular therapy.~5. Pregnancy; if a woman is of child-bearing potential a urine or serum beta HCG test is positive.~6. Severe contrast allergy or absolute contraindication to iodinated contrast.~7. Suspected intracranial dissection as a cause of stroke.~8. Clinical history, past imaging or clinical judgment suggests that the intracranial occlusion is chronic.~9. Patient has a severe or fatal comorbid illness that will prevent improvement or follow-up or that will render the procedure unlikely to benefit the patient.
