Clot Lysis: Evaluated Accelerated Resolution of Intraventricular Hemorrhage

Clinical Trial Title: 
Clot Lysis: Evaluated Accelerated Resolution of Intraventricular Hemorrhage (CLEAR-III)
Clinical Trial Protocol ID: 
08100901
Clinical Trial Investigator Name: 
Sayona John, MD
Clinical Trial Protocol Description: 

Intraventricular hemorrhage (IVH) occurs in about 40 percent of primary intracerebral hemorrhage (ICH) and 15 percent of aneurysmal subarachnoid hemorrhage. IVH is a significant and independent contributor to morbidity and mortality in both. Previous studies have demonstrated benefits to treating IVH using extraventricular drains (EVD) in combination with thrombolytic therapy of rt-PA to accelerate blood clot resolution.

CLEAR-III is a multicenter, international, double-blind, randomized study comparing the long-term functional outcomes of lysing ventricular blood clots using EVD combined with rt-PA against EVD compared with placebo (saline) for the treatment of severe IVH.

Clinical Trial Eligibility Criteria: 

You may be eligible to participate in this study if you:

  • Are an adult between 18 and 80 years of age
  • Have symptom onset less than 24 hours prior to diagnostic CT
  • Have spontaneous ICH ≤ 30 cc and IVH obstructing the third and/or fourth ventricles

You will be excluded from this study if you:

  • Have suspected or untreated ruptured cerebral aneurysm, ruptured intracranial AVM or tumor
  • Have presence of a choroid plexus malformation or Moyamoya disease
  • Have clotting disorders
  • Are pregnant
