1. Be =12 years of age.
2. Have a confirmed diagnosis of HAE with a history of at least one of the following:
• C1 INH antigen level below normal
• Functional C1 INH level below normal
3. If currently receiving prophylactic IV CINRYZE therapy (i.e., 1000 U every 3 or 4 days or up to 2000 U per week) or other C1 INH therapy,
have:
• during the 3 consecutive months prior to randomization, an angioedema attack rate of =1.0 moderate or severe attack per month (average).
NOTE: if the duration of prophylactic therapy is <3 months, but at least 1 month, the subject should satisfy this attack rate (i.e., =1.0 moderate or severe attack per month [average]) for the timeframe that the subject has actually received prophylactic therapy.
AND
• during the 3 consecutive months prior to starting prophylactic therapy, a history of at least 2.0 moderate or severe angioedema attacks per month (average).
NOTE: the attack rate may be estimated based on subject recall.
4. If not on prophylactic C1 INH therapy, have a history of at least 2.0 moderate or severe angioedema attacks per month (average) during the
3 consecutive months prior to randomization.
NOTE: the attack rate may be estimated based on subject recall.
5. Agree to avoid his/her known HAE triggers during the study to the best of his/her ability.
6. Agree to adhere to the protocol-defined schedule of assessments and procedures.
7. If female, be post-menopausal (cessation of menses greater than or equal to 1 year), surgically sterile, or following an acceptable nonhormonal
method of birth control such as intrauterine device or barrier control for at least 1 complete menstrual cycle before the screening visit and agree to continue
use through the 30-day post-treatment visit, or using hormonal birth control products for at least 3 months prior to the first dose of study drug in Treatment Period 1 and agree to continue use through the 30- day post-treatment visit.
8. If male, be surgically sterile or agree to follow an acceptable method of birth control (e.g., barrier control) from the screening visit through 2 months after the last dose of study drug.
9. If an adult (=18 years of age), be informed of the nature of the study and provide written informed consent before any study-specific procedures are performed.
OR
If a child (<18 years of age), have a parent(s)/legal guardian who is informed of the nature of the study provide written informed consent for the child to participate in the study before any study-specific procedures are performed (with assent from the child when appropriate). Alternatively, certain sites/IRAs may permit adolescents who are <18 years of age to be informed of the nature of the study and provide
written informed consent without consent from a parent(s)/legal guardian.
