Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
110 patients were randomized to the trial, and 31 were recruited as pilot patients.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Each study center was required to demonstrate proficiency in the technical aspects of enrollment, stabilization, surgery, and drug administration. This proficiency was demonstrated on at least one pilot patient prior to randomization of the first patient in the investigational cohort of 110 randomized patients.

Reporting Groups
  Description
Medical Management Standard of care medical management as per American Heart Association (AHA) guidelines.
MISTIE Surgical Management

Minimally invasive surgery (MIS) with clot lysis with recombinant tissue plasminogen activator (rt-PA).

MIS+Cathflo Activase (drug): The intervention is a comparison of the safety and preliminary effectiveness of investigational minimally invasive surgery to place a catheter into an intracerebral hemorrhage blood clot and subsequent administration in sequential tiers of 0.3 or 1.0mg of rt-PA, CathFlo® through the catheter once every eight hours for up to 72 hours, in addition to best medical care.

This includes 54 intent-to-treat patients, and excludes 27 pilots.

ICES Surgical Management

Intraoperative stereotactic CT-Guided Endoscopic Surgery (ICES)

Mechanical intracerebral hemorrhage removal via an endoscope utilizing the same operative-targeting arm as MISTIE arm. Best medical care was provided, but no rt-PA was administered.

This includes 14 intent-to-treat patients, and excludes 4 pilots.
