Study summary

The purpose of the study is to assess the safety and effectiveness of the Pipeline™ Flex Embolization Device with Shield Technology™ in the treatment with acutely ruptured intracranial aneurysms.

Read the detailed description

The ELEVATE study is a prospective, multi-center, single-arm trial of the Pipeline™ Shield Device for the treatment of adults with acutely ruptured intracranial aneurysms. The primary objective of the ELEVATE study is to assess the safety and effectiveness of treatment with the Pipeline™ Shield Device of acutely ruptured intracranial aneurysms that are not amenable for clipping and coiling.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Subject has a previously untreated, wide neck, side-wall, intradural aneurysm that is deemed unfavorable for both surgical clipping and endovascular coiling, as confirmed on DSA.

Exclusion criteria

Exclusion Criteria:

  1. Subject's vessel characteristics preclude safe endovascular access to the aneurysm to treat with the Pipeline™ Shield Device.
  2. Subject has aneurysm vessel characteristics that would preclude the device from fully conforming to the parent vessel to reduce any risk of embolic complications, retreatment, or device movement.

  8. Subject has a target ruptured aneurysm that is thought to be mycotic, including those caused by left atrial myxoma, or subject has an active systemic bacterial infection.
  9. Subject with a requirement for continuous anti-coagulation.
  10. Subject has a malignant brain tumor or vascular malformation (e.g. arteriovenous malformation).
  11. Subject's target ruptured aneurysm has not been determined by the treating physician to be the source of SAH.
  12. Subject with known allergy to platinum or cobalt chromium alloy (including the major elements platinum, cobalt, chromium, nickel or molybdenum).
  13. Subject has a known to ticagrelor or aspirin.
  14. Subject is unable to undergo DSA or DSA is determined unsuitable by the treating physician.
  15. Subject has a serious or life-threatening comorbidity that could confound study results.
  16. Subject is at high risk of noncompliance per treating physician due to reasons including but not limited to a history of substance abuse.
  17. Subject is unable to complete scheduled follow-up assessments due to comorbidities, geographical limitations, or a of less than 24 months.
  18. Subject is pregnant, or breastfeeding at the time of admission or plans to become pregnant during their participation in the study.
  19. Subject is participating in another clinical study at the time of enrollment.
  20. Presumed septic embolus, or suspicion of microbial superinfection.
  21. Subject with a known COVID-19 viral infection, confirmed by testing.
  22. Subject in whom a pre-existing stent is in place in the parent artery at target aneurysm location.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

What researchers measure

Primary outcomes

  1. Incidence of complete angiographic occlusion without significant stenosis, and no rebleeding or retreatment of the target aneurysm

    Occlusion is measured by the Raymond Roy Scale. Significant stenosis is classified as ≤ 50%.

    Time frame: at 365-day

  2. Incidence of neurological death or disabling stroke post-procedure.

    Disabling stroke is defined as any post-procedural ischemic or hemorrhagic event that results in poor functional outcome (i.e. mRS ≥ 3 points) assessed at 90 days post stroke event.

    Time frame: at 365-day

Secondary outcomes

  1. Pipeline™ Flex Device Deployment Success Rate

    Time frame: Day 0 During Procedure

  2. Incidence of rebleed of target aneurysm

    Time frame: through 180-day and 365-day post procedure

  3. Incidence of neurological hemorrhagic serious adverse events

    Time frame: through 180-day and 365-day post procedure

  4. Incidence of ipsilateral major stroke or neurological death post-procedure after 30 days

    Time frame: through 180-day and 365-day post procedure

  5. Incidence of any ipsilateral stroke post-procedure after 30 days

    Time frame: through 180-day and 365-day post procedure

  6. Good clinical outcome (modified Rankin Scale (mRS) 0-2)

    Scale for measuring general neurologic function: 0- No symptoms at all 1. No significant disability despite symptoms; able to carry out all usual duties and activities 2. Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance 3. Moderate disability; requiring some help, but able to walk without assistance 4. Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance 5. Severe disability; bedridden, incontinent and requiring constant nursing care and attention 6. Dead

    Time frame: at 30-day, 180-day and 365-day post procedure

  7. Incidence of parent artery thrombosis

    Time frame: through 365-day post procedure

  8. Incidence of in-construct stenosis > 50%

    Time frame: through 365-day post procedure

  9. Incidence of retreatment

    Time frame: through 180-day and 365-day post procedure

  10. Incidence of peri-/post-procedural serious adverse events related to the device, procedure or antiplatelet therapy

    Time frame: through 180-day and 365-day post procedure

  11. Incidence of neurological death or disabling stroke

    Time frame: through 365-day post procedure

  12. Incidence of complete angiographic occlusion without significant stenosis (≤ 50%), and no rebleeding or retreatment of the target aneurysm

    Time frame: through 365-day post procedure

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 27, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
