About this study

Official title: INVEST-REGISTRY: Minimally Invasive Endoscopic Surgical Treatment With Apollo/Artemis in Patients With Brain Hemorrhage: A Prospective Multicenter Registry

Objective: The primary objective of this multicenter prospective registry is to provide additional safety, technical outcomes and clinical outcomes data for minimally invasive endoscopic surgery (MIES) with Apollo or Artemis for the evacuation of supratentorial brain hemorrhage in adult patients who do not qualify for the concurrent INVEST Feasibility randomized controlled trial at active INVEST centers.

Read the detailed description

Study Design: This study will be a prospective, non-randomized, multi-center, single arm registry that will enroll up to 50 patients, however may increase to 200 at up to 10 US centers.

Patient Population: Adult patients with supratentorial brain hemorrhages (ICH and/or IVH) who do not meet all INCLUSION criteria or who meet one or more EXCLUSION criteria for the INVEST trial, but who will ultimately undergo MIES with Apollo or Artemis at active INVEST centers.

Indication: The Artemis Neuro Evacuation Device is used for the controlled aspiration of tissue and/or fluid during surgery of the Ventricular System or Cerebrum in conjunction with a Penumbra Aspiration Pump. The Penumbra Aspiration Pump is indicated as a vacuum source for the Penumbra Aspiration Systems. The Apollo system has been cleared for the controlled aspiration of soft tissue and/or fluid during endoscopically guided neurosurgery of the ventricular system. In the present study, the researchers propose to investigate the safety and efficacy of this system for the minimally invasive evacuation of brain hemorrhage - both IVH, IVH with ICH and ICH alone - in patients who do not qualify for the INVEST trial.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Apollo DeviceDevice

    Also called ICH - Apollo System

    The Apollo system has been cleared for the controlled aspiration of soft tissue and/or fluid during endoscopically guided neurosurgery of the ventricular system.

  • Artemis DeviceDevice

    The Artemis Neuro Evacuation Device is used for the controlled aspiration of tissue and/or fluid during surgery of the Ventricular System or Cerebrum in conjunction with a Penumbra Aspiration Pump. The Penumbra Aspiration Pump is indicated as a vacuum source for the Penumbra Aspiration Systems.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Modified Rankin Score (mRS) ≤ 3 or mRS > 3

    Clinical Efficacy Endpoint: global disability assessed via the modified Rankin score (mRS). 180-day global disability assessed via the modified Rankin score (mRS), categorized as either mRS ≤ 3 or mRS > 3

    Measured: 180 days

  2. Number of Participants With Surgical Success Rate

    Technical Efficacy Endpoint measured by rate of surgical success. Surgical Success Rate is defined as reduction to < 15 cc total volume AND >60% reduction in hemorrhage volume on immediate post-treatment CT scan

    Measured: immediately post-procedure

  3. Number of Participants With Surgical Success Rate Regarding IVH

    Technical Efficacy Endpoint measured by rate of surgical success. Surgical Success Rate is defined as Intraventricular hemorrhage (IVH): mGraeb score of < 5 on day 7 CT scan

    Measured: 7 days post-procedure

  4. Rate of Mortality

    Measured: 30 days post procedure

Secondary outcomes (4)

    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

    Measured: 30 days post-procedure

  2. Modified Rankin Score (mRS) at 90 Days

    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

    Measured: 90 days post-procedure

  3. Length of Hospital Stay

    Measured: average of 17 days

  4. Number of Participants Requiring VPS

    Number of participants requiring Ventriculoperitoneal Shunt (VPS)

    Measured: average of 17 days

Questions about this trial

What is this clinical trial studying?

A study testing Apollo Device and Artemis Device in people with Intracranial Hemorrhage, run by J. Mocco at 7 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Jun 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Modified Rankin Score (mRS) ≤ 3 or mRS > 3 (time frame: 180 days). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jun 2025.
