MeasureTime frame
Main Objective: To evaluate the efficacy of 1000 U and 2000 U doses of CINRYZE with rHuPH20 administered by SC injection to prevent angiodema attacks. To assess the safety and tolerability of CINRYZE with rHuPH20 administered by SC injection.;Secondary Objective: To determine the optimal dose of CINRYZE with rHuPH20 administered by SC injection for prevention of angioedema attacks based upon benefit-risk assessment. To further characterize the PK/PD of CINRYZE with rHuPH20 administered by SC injection. To assess the immunogenicity of CINRYZE with rHuPH20 following SC administration. To assess subject acceptance of SC administration of CINRYZE with rHuPH20 for prevention of angioedema attacks. To evaluate subject experience with self administration of SC CINRYZE with rHuPH20. To assess health status (quality of life) of this patient population.;Primary end point(s): The primary efficacy endpoint is the number of angioedema attacks recorded during each treatment period, normalized for the number of days the subject participated in that period.;Timepoint(s) of evaluation of this end point: End of the treatment period.;Main Objective: To evaluate the efficacy of 1000 U and 2000 U doses of CINRYZE with rHuPH20 administered by SC injection to prevent angiodema attacks.
