Brief Summary

STEP is a Randomized, Multifactorial, Adaptive Platform trial that seeks to optimize the care of patients with acute ischemic stroke (AIS) due to large (LVO) or medium vessel occlusions (MVO).

Detailed Description

The StrokeNet Thrombectomy Endovascular Platform (STEP) is conducted within NIH StrokeNet at 38 comprehensive stroke centers across the US. The primary goal is to optimize all aspects of care of acute ischemic stroke patients with a large or a medium vessel occlusion. The platform trial operates under an overarching Master Protocol in an inferentially integrated framework. The platform trial is designed to support the studies of three broad categories of therapeutics: expansion of endovascular treatment (EVT) indications, innovative EVT devices and concomitant medical therapies, and novel pre- and early-hospital technologies and systems of care. As new interventions are put forth, they will be added to the Master Protocol as a new Domain or part of an existing Domain. STEP utilizes a flexible Bayesian design with frequent adaptive analyses to assess whether a given intervention is superior, inferior, or equivalent either within a Domain or for specific populations within the Domain.

Endovascular Therapy (EVT) Indication Expansion Domain: Medium/Distal Occlusions StrataMedical ManagementAdult patients with acute cerebral ischemia within 24 hours of last known who have Medium Vessel Occlusion (MVO) with Non-dominant/Co-dominant M2 occlusion or Distal Medium Vessel Occlusion (DMVO) patients with M3,4 or A1,2,3 or P1,2,3 occlusion will be randomized to receive one of two strategies: * Endovascular Therapy (EVT) * Medical Management (MM)
Endovascular Therapy (EVT) Indication Expansion Domain: Low NIHSS StrataMedical ManagementAdult patients with acute cerebral ischemia within 24 hours of last known well who have large vessel occlusion (LVO) and mild deficits/low NIHSS (NIHSS 0-5) will be randomized to receive one of two strategies: * Endovascular Therapy (EVT) * Medical Management (MM)

Primary Outcome Measures
NameTimeMethod
Global disability measured by Modified Rankin Score90-day

The modified Rankin Score is a 7-outcome ordinal scale where 0 = No symptoms and 6= Dead.

The analysis of the primary endpoint will be based on a utility weighting of the 7 outcomes, where 0 represents the worst possible health state and 1 represents the best possible state.
