Summary:

      The overall objective of this Phase III clinical trial is to obtain information from a
      population of 500 ICH subjects with intraventricular hemorrhage (IVH), representative of
      current clinical practice and national demographics of ICH regarding the benefit (or lack
      thereof) of IVH clot removal on subject function as measured by modified Rankin Scale (mRS).
      This application requests funding for five years to initiate a Phase III randomized clinical
      trial (RCT) testing the benefit of clot removal for intraventricular hemorrhage. The
      investigators propose to compare extraventricular drainage (EVD) use plus recombinant tissue
      plasminogen activator (rt-PA; Alteplase; Genentech, Inc., San Francisco, CA) with EVD+
      placebo in the management and treatment of subjects with small intracerebral hemorrhage (ICH)
      and large intraventricular hemorrhage (IVH defined as ICH < 30 cc and obstruction of the 3rd
      or 4th ventricles by intraventricular blood clot).
