FORWARD: Functional Outcomes in Real-World Treatment And Revascularization of Non-dominant and Distal M2 Occlusions

5. august 2026 opdateret af: Penumbra Inc.
The objective of this study is to collect safety and effectiveness data on the Penumbra System reperfusion catheters in participants with isolated primary non-dominant and distal M2 occlusions who undergo endovascular mechanical thrombectomy (EVT). Additionally, this study aims to observe characteristics and outcomes of participants treated with medical management (MM) alone and those who receive EVT + MM per current medical practice.

Participants experiencing acute ischemic stroke (AIS) due to a primary M2 occlusion in the vertical segment or post-bifurcation in the non-dominant or co-dominant branch of the horizontal segment.

Beskrivelse

Inclusion Criteria:

  1. Participant age ≥ 18
  2. Participant experiencing acute ischemic stroke due to a confirmed primary M2 occlusion in the vertical segment or post-bifurcation in the non-dominant or co-dominant branch of the horizontal segment
  3. NIHSS ≥5 or NIHSS 3-4 with disabling symptoms
  4. Pre-stroke mRS 0-1
  5. For participants undergoing thrombectomy: Planned first-line treatment with Penumbra System reperfusion catheters
  6. Informed consent obtained per Institutional Review Board/Ethics Committee requirements

Exclusion Criteria:

  1. Any stenosis or occlusion in the ICA origin requiring treatment during the procedure or within the 90-day follow-up period.
  2. Known multiple occlusions
  3. Secondary M2 occlusion
  4. Known or high suspicion of underlying ICAD as the cause of the M2 occlusion
  5. Current hospitalization at time of stroke onset and/or any comorbid disease or condition expected to compromise survival or ability to complete follow-up assessments through 90 days
  6. Currently participating in an investigational (drug, device, etc.) clinical trial that will influence the endovascular procedure or acute treatment. Participants in secondary prevention, observational, natural history and/or epidemiological studies are eligible.
  7. Other medical, behavioral, or psychological conditions that in the opinion of the Investigator could limit the ability to participate in the study, including compliance with follow-up requirements, or that could impact the scientific integrity of the study

Change in NIHSS at 24 hours
Tidsramme: 24 hours
The National Institutes of Health Stroke Scale (NIHSS) is a standardized neurological examination tool used to measure the severity of a stroke. The scale ranges from 0 to 42, with higher scores indicating greater impairment.

Tidsramme
90-day Modified Rankin Scale (mRS)
Tidsramme: 90 Days
The modified Rankin Scale (mRS) is used to measure the degree of disability or dependence in daily activities in people who have experienced a stroke. Scores range from no symptoms (0) to death (6), with higher scores indicating greater severity.

90 Days
Quality of Life, as measured by Barthel Index
Tidsramme: 90 Days
The Barthel Index is a 0-100 point scale used to measure a person's functional independence in daily activities. The index rates 10 items, including feeding, bathing, grooming, dressing, bowel/bladder control, toilet use, transfers, mobility, and stair use. Higher scores indicate greater independence, while lower scores signify higher dependency on caregivers.
90 Days
Quality of Life, as measured by Neuro-QoL
Tidsramme: 90 Days
Neuro-QoL is a set of patient-reported outcome measures designed to assess health-related quality of life across physical, mental, and social domains relevant to individuals with neurological conditions. It uses calibrated item banks and short forms to measure constructs such as mobility, cognitive function, emotional/behavioral health, fatigue, and social participation.
90 Days
Quality of Life, as measured by Canadian Outcome Scale for Minor Stroke (COSMOS)
Tidsramme: 90 Days
COSMOS is a 7-point scale ranging from 0 (no symptoms) to 6 (loss of independence for an instrumental or basic activity of daily living or worse), which accounts for performance limitations and losses of a person's hobbies or passions and of their employment, educational, service, or caregiving pursuits, besides just activities of daily living.
