Primary Outcome Measures :
  1. Proportion of attacks treated with successful outcome [ Time Frame: 24 hours ]
    successful outcome is defined as attack resolution begun within 4 hrs after treatment and maintained for 24 hours

  2. Proportion of attacks with a partial response [ Time Frame: 24 hours ]
    partial response is defined as an initial response to dosing followed by a relapse within 4 to 24 hours

Secondary Outcome Measures :
  1. Proportion of patients who respond to a 2nd dose of ecallantide after an initial, partial response [ Time Frame: 24 hours ]
  2. Time to resolution onset of each acute attack, as determined by patient report [ Time Frame: 24 hours ]
