Minimal Invasive Surgical Intracerebral Hemorrhage Removal (HEALME)
Hyperacute mEchAnicaL Endoscopic Minimally Invasive Surgical (MIS) Intracranial Hemorrhage Evacuation
This is a feasibility study trial to determine whether hyperacute (≤8 hour) mechanical Minimal Invasive Surgical (MIS) management is feasible and secondarily improves outcome in patients with spontaneous supratentorial intracranial hemorrhage (ICH).
Patients meeting the inclusion and exclusion criteria, will be enrolled and randomized to either minimally invasive hematoma evacuation (MIS) or best medical management alone (MM). Subjects will be randomly assigned by a central web-based system in a 3:1 manner to treatment with MIS or MM. Data for each subject will be collected at the time of enrollment and treatment, and at subsequent follow-up visits.

Detailed Description
The proposed study seeks to determine whether hyperacute (≤8 hour) mechanical MIS management is feasible and improves outcome in patients with spontaneous supratentorial intracranial hemorrhage (ICH).
- Screening The subject will be evaluated as any non-traumatic spontaneous intra-parenchymal hemorrhage patient including medical history screened, available clinical/neurological exams (focused exam, NIHSS, GCS, historical mRS), ECG, laboratory work, and imaging information per institutional standard of care. A CTA (or MRA) will be performed, as standard of care.
- Randomization After all inclusion and exclusion criteria are confirmed and written informed consent obtained, randomization will occur. Subjects will be randomized to best MM or MIS.
- Treatment Procedure (if randomized to MIS) Minimally Invasive Surgical evacuation.
- Treatment Procedure (if randomized to MM) There is no intervention for the control group beyond the current standard of care provided at The Ottawa Hospital. Subjects randomized to the MM group will receive best MM for ICH according to Canadian Best Practice Recommendations for ICH care. Outcomes assessments will be in accordance to table 2.
- Post procedure, D1, D2 and D5 or discharging A post-procedural computed tomographic scan will be obtained within 24 hours (± 6 hours) for MIS group. Clinical assessment such as NIHSS, mRS, NCCT head, computed tomographic Angiogram, adverse event assessment will be conducted as SOC for MIS group (Table 2 in protocol).
A CT will be obtained in MM subjects 24 hours (± 6 hours) after randomization. Adverse event assessment will be conducted for MM subjects 4-6 hours after randomization. Neurological and functional exams will be conducted in D1 and D2 after randomization (Table 2 in protocol).
Follow-up visits (D30, D90): (Both MIS and MM groups) Follow-ups will be combined with phone and onsite visit. D30 will be conducted over the phone, and D90 will be onsite visit. The follow-ups will involve clinical assessment such as NIHSS, Glasgow Coma Scale, EuroQol- 5 Dimension (EQ-5D), mRS, Barthel, Glasgow Outcome Scale (GOSE), adverse event assessment, concomitant. medications.

Experimental: Mechanical Minimal Invasive Surgical (MIS) management
Minimally invasive hematoma evacuation with the Artemis Neuro Evacuation Device with medical management
|
Patients randomized to MIS group will be undergoing an intervention will get Minimal Invasive Surgical treatment. The market approved Artemis Device (MIS group) will be used. The Artemis Device, Aspiration Pump, and endoscope are used to rinse (irrigate) this area and to gently suction out the rinsing fluid and any blood or clot in brain. The Device is also designed to prevent clogging during the suction of fluid and blood. |
No Intervention: Best Medical Management (MM)
Best medical management per standard of care

EQ-5D-5L stands for European Quality of Life Five Dimension, the 5-level EQ-5D version (EQ-5D-5L), which was introduced by European Quality of Life Scale group in 2009. EQ-5D-5L is used for self-assessment on activities of daily living. The EQ-5D-5L comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: LEVEL 1: indicating no problem LEVEL 2: indicating slight problems LEVEL 3: indicating moderate problems LEVEL 4: indicating severe problems LEVEL 5: indicating unable to/extreme problems |
