About

Early hematoma growth (HG) after spontaneous intra-cerebral/intra-parenchymal hemorrhage (IPH) is common and associated with neurological deterioration and poor clinical outcome. Temperature modulation to hypothermia (Temperature, 32-34°C) has been associated with reduction or improvement of physiopathologic processes associated with inflammatory activation and degradation of blood-brain barrier after all types of brain injury. In this sense, we believe that the initiation of an ultra-early protocol of active temperature modulation or Targeted Temperature Management (TTM) to mild induced hypothermia (MIH, 32-34°C) may be associated with good safety and tolerability profile, less HG and cerebral edema after IPH by modulation of systemic and local inflammatory responses, so we hypothesize that TTM to MIH will be a safe/tolerable and effective therapy to limit HG and cerebral edema after IPH.

Full description

In this randomized clinical trial, patients with IPH within 6 hours of onset will be randomized to one of two study arms. In one arm, patients will have 72 hours of TTM to MIH (32-34 degree Celcius). In the second arm, patients will have 72 hours of TTM to Normal Temperature (NT)(36-37 degrees Celcius). Subjects in all arms will otherwise receive identical therapeutic interventions pre-defined by our local IPH management protocol. Primary outcomes are examining the frequency of adverse events (AEs) that will be possibly or probably related to treatment. AEs will be assessed up to 15-days after admission or discharge if earlier and the frequency of severe adverse events (SAEs) that will be possibly and probably related to treatment. SAEs will be assessed up to 90-days. The secondary outcome measures will be in-hospital neurological deterioration between day 0-7 (decrease in GCS10 in ≥2 points, or increase in the NIHSS11 ≥4 points), in-hospital mortality, modified Rankin Score [mRS]12 at discharge and 90-days. To determine whether TTM to MIH can limit HG and cerebral edema, will be examining absolute change in hematoma between baseline and 24 hours, new or absolute change in IVH between baseline and 24 hours, the proportion of patients with HG, absolute change in hemostatic proteins, the absolute change in cerebral edema between baseline and 24, 48,72, and 168-hours, relative change in cerebral edema.
