Study summary

Prospective, single-arm, multi-center study to confirm the performance and safety of the iNstroke 6F and 4F thromboaspiration catheter for the treatment of acute ischemic stroke

Read the detailed description

This clinical investigation has been designed to generate further data demonstrating the safety and effectiveness of the iNstroke device as well as of the thrombectomy process for the treatment of large and medium vessel occlusions.

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. Patients ≥ 18 years of age.
  2. Able to be treated (i.e., defined by arterial puncture time) within 24 hours of symptom onset or last time seen well (LTSW).
  3. Demonstrated occlusion in a large and/or medium vessel (carotid T, M1, proximal M2, M2-M3, A1, A2, A3, basilar artery, P1, P2, P3).
  4. Baseline NIHSS score ≥6 assessed before the procedure.
  5. Pre-morbid [xB13.1]stroke baseline mRS ≤ 2.
  6. Subjects with an ASPECTS ≥ 6.
  7. signed by the subject or their representative, or notice of information, as per regulatory requirements, to collect the subject's data.
  8. As applicable by French laws, the subject is affiliated to a health social security regimen or equivalent (only to be answered by French sites).

Exclusion criteria

Exclusion Criteria:

  1. Severe comorbidity and/or shortened that will likely prevent improvement or follow up or that will render the procedure unlikely to benefit the patient.
  2. Severe allergy to contrast media.
  3. As applicable by French laws: breastfeeding women, persons deprived of their liberty by a judicial or administrative decision, or persons of full age who are the subject of a legal protection measure.
  4. Patients with intracranial atherosclerotic occlusive disease or extra- or intracranial dissection.
  5. Multiple Intracranial Occlusions
  6. Known medical history of thrombocytopenia ( \<100,000).
  7. Presence of intracerebral hemorrhage.
  8. Significant mass effect and/or midline shift.
  9. Evidence of intracranial tumor (except small meningioma).
  10. Intracranial stenosis proximal to the occlusion.
  11. Severe sustained hypertension (systolic pressure >185 mm Hg or diastolic pressure >110 mm Hg). Note: If blood pressure can be successfully reduced and maintained at an acceptable level by administering the medication recommended by the ESO (European Stroke Organisation) in its guidelines (also IV infusion of antihypertensives), the patient may be included.
  12. Known or suspected cerebral vasculitis.
  13. Known renal insufficiency with creatinine ≥3 mg/dl or (GFR) \<30 mL/min.
  14. Current participation in an interventional drug or device study that may confound the results of this study.
Terms in these criteria, in plain language(4)

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.

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.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

ElapsedEstimatedEstimated, not yet reachedDate before it movedWhere the date was before it movedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Nov 2026; primary completion for Aug 2027, 9 months later.

Of 81 industry-sponsored interventional studies with no phase under Ischemic Stroke, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 46. This study's planned 9 months is below that.

Counting every sponsor, half of 653 studies reached it within 27 months; a quarter within 14 and three quarters within 48.

Since we started tracking on Sep 25, 2026, the dates moved once, on Nov 4, 2026: start May 2026 → Nov 2026 and primary completion Feb 2027 → Aug 2027.

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.
