Study summary

The purpose of this study is to collect medical information to monitor the ongoing safety of the J\&J MedTech devices and to understand how well they work when routinely used to treat participants with acute ischemic stroke (a condition caused by a blocked blood vessel in the brain).

Study population

The study population will include participants with angiographic confirmation of acute ischemic stroke who are scheduled to undergo/have undergone mechanical thrombectomy using one or more of the study devices as specified in the protocol.

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

  • Participant is 18 years of age or older at the time of consent
  • has been provided by the participant or the participants' legally authorized representative (LAR)
  • Participants with angiographic confirmation of acute ischemic stroke
  • A clinical decision has been made to treat the participant with an eligible Johnson \& Johnson MedTech neuro-thrombectomy device independently and prior to enrollment in the study

Exclusion criteria

Exclusion criteria:

  • Known pregnancy, as evidenced by positive pregnancy test for women of or breast feeding
  • Current involvement in an (drug, device, etcetera) clinical study that may confound study endpoints. Sponsor approval is required prior to enrollment
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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Groups and cohorts

  • Participants With Acute Ischemic Stroke

    Participants with angiographic confirmation of acute ischemic stroke who are scheduled to undergo/have undergone mechanical thrombectomy using one or more of the study devices will be enrolled. Participants will have the procedure according to the standard of care (SOC) process of the hospital and physician preference. No treatment will be provided by the sponsor as a part of this study.

What researchers measure

Primary outcomes

  1. Revascularization (Modified Thrombolysis in Cerebrovascular Infarction [mTICI])

    Revascularization is defined as achieving a specific minimum mTICI score, such as 2b or greater. mTICI is a 6-point grading system for determining the response of thrombolytic therapy for ischaemic stroke with grades as follows: mTICI 0 = no perfusion; mTICI 1 = penetration but not perfusion; mTICI 2a = some perfusion with distal branch filling of less than (\<)50 percent (%) of territory visualized; mTICI 2b = substantial perfusion with distal branch filling of \>=50% of territory visualized; mTICI 2c = near-complete perfusion; mTICI 3 = complete perfusion.

    Time frame: Up to 90 days post-procedure

Secondary outcomes

  1. Percentage of Participants With Modified Rankin Scale (mRS) Score of <=2 or no Worsening at 90 Days

    Percentage of participants with mRS score of \<=2, or no worsening from baseline, at 90 days will be reported. The mRS is a commonly used 7-point disability scale with possible scores ranging from 0 (no symptoms) to 6 (Death).

    Time frame: At 90 days post-procedure

  2. 90-Day All-Cause Mortality

    All mortality regardless of causes through 90 days post procedure will be reported.

    Time frame: At 90 Days Post-Procedure
