Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Be a child (male or female) 2 to lesser than (<) 12 years of age at the time of screening.
  • Documented diagnosis of HAE (Type I or II) based upon both of the following:

    1. Documented clinical history consistent with HAE (SC or mucosal, nonpruritic swelling episodes without accompanying urticarial).
    2. Diagnostic testing results obtained during screening from a sponsor- approved central laboratory that confirm C1-INH functional level <40 percent (%) of the normal level. Participants with functional C1 esterase inhibitor (C1-INH) level 40-50% of the normal level may be enrolled if they also have a complement4 (C4) level below the normal range. With prior sponsor approval, participants may be retested during the baseline observation period if results are incongruent with clinical history or believed by the investigator to be confounded by recent complement1 (C1) inhibitor use.
  • A historical baseline HAE attack rate of at least 1 attack per 3 months. Note: In addition,participants who experience greater than or equal to (>=)1.0 angioedema attacks per three months during the 12-week baseline observation period and who remain eligible per the inclusion criteria will enter the lanadelumab treatment period.
  • Agree to adhere to the protocol-defined schedule of treatments, assessments, and procedures.
  • Have a parent(s)/legal guardian who is informed of the nature of the study and can 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).
  • Females of childbearing potential must agree to be abstinent or agree to comply with the applicable contraceptive requirements of this protocol through the duration of the study from screening through 70 days after the final study visit.

Exclusion Criteria:

  • Concomitant diagnosis of another form of chronic, recurrent angioedema, such as acquired angioedema (AAE), HAE with normal C1-INH, idiopathic angioedema, or recurrent angioedema associated with urticaria.
  • Dosing with an investigational drug or exposure to an investigational device within 4 weeks prior to screening.
  • Be pregnant or breastfeeding.
  • Have initiated androgen treatment (eg, stanozolol, danazol, oxandrolone, methyltestosterone, and testosterone) within 2 weeks prior to entering the observation period.
  • Exposure to angiotensin-converting enzyme (ACE) inhibitors or any estrogen-containing medications with systemic absorption (such as oral contraceptives or hormonal replacement therapy) within 4 weeks prior to screening.
  • Have any active infectious illness or fever defined as an oral temperature greater than (>) 38 degree celsius (°C) (100.4 fahrenheit [°F]), tympanic > 38.5°C (101.3°F) , axillary >38°C (100.4°F), or rectal/core >38.5°C (101.3°F) within 24 hours prior to the first dose of study drug in treatment period A.
  • Have any HAE attack that is not resolved prior to the first dose of study drug in treatment period A.
  • Have any of the following liver function test abnormalities: alanine aminotransferase (ALT) >3x upper limit of normal (ULN), or aspartate aminotransferase (AST) >3x ULN, or total bilirubin >2x ULN (unless the bilirubin elevation is a result of Gilbert's syndrome).
  • Have any condition (any surgical or medical condition) that, in the opinion of the investigator or sponsor, may compromise their safety or compliance, preclude the successful conduct of the study, or interfere with interpretation of the results (eg, significant pre-existing illness or other major comorbidity that the investigator considers may confound the interpretation of study results).
  • Participant has a known hypersensitivity to the investigational product or its components.
