Outcome Measures
Primary Outcomes (1)
Number of Participants Achieving Attack-Free Status for the Efficacy Evaluation Period of Day 0 Through Day 182
A participant was considered as attack free during an efficacy evaluation period if the participant had no investigator-confirmed hereditary angioedema (HAE) attacks during that efficacy evaluation period. A HAE attack was defined as the symptoms or signs consistent with an attack in at least 1 of the following locations: peripheral angioedema (cutaneous swelling involving an extremity, the face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain, with or without abdominal distention, nausea, vomiting, or diarrhea), laryngeal angioedema (stridor, dyspnea, difficulty speaking, difficulty swallowing, throat tightening, or swelling of the tongue, palate, uvula, or larynx). Number of participants achieving attack-free status for the efficacy evaluation period of Day 0 through Day 182 were assessed.

Number of High-Morbidity Investigator-Confirmed Hereditary Angioedema (HAE) Attacks During Each of the Efficacy Evaluation Periods
Day 0 through Day 182, Day 0 through Day 364, Day 70 through Day 182, Day 70 through Day 364

Study Arms (1)
Lanadelumab 300 mg q2w or q4w
EXPERIMENTALLanadelumab 300 mg solution, subcutaneously (SC), once every 2 weeks (q2w) for 26 weeks in Treatment Period A. This was followed by Treatment Period B (additional 26 weeks, total of 52 weeks including Treatment Period A) during which participants remained on Treatment Period A regimen or received 300 mg lanadelumab solution once every 4 weeks (q4w) for 26 weeks if well-controlled (attack-free) for 26 consecutive weeks with lanadelumab treatment. The dose frequency change was based on the Investigator's discretion and approval by the Sponsor's Medical Monitor.
Interventions
Lanadelumab solution, SC
Eligibility Criteria
You may qualify if:
- Be of Japanese descent, defined as born in Japan and having Japanese parents and Japanese maternal and paternal grandparents.
- The participant is male or female and \>= 12 years of age at the time of informed consent.
- Documented diagnosis of HAE (Type I or II) based upon all of the following:
- Documented clinical history consistent with HAE (subcutaneous or mucosal, nonpruritic swelling episodes without accompanying urticaria).
- Diagnostic testing results obtained during screening that confirm HAE Type I or II: C1 inhibitor (C1-INH) functional level \<40% of the normal level. Participants with functional C1-INH level 40-50% of the normal level may be enrolled if they also have a C4 level below the normal range. With prior sponsor approval, participants may be retested during the run-in period if results are in congruent with clinical history or believed by the investigator to be confounded by recent C1 inhibitor use.
- At least one of the following: age at reported onset of first angioedema symptoms \<=30 years, a family history consistent with HAE Type I or II, or C1q within normal range.
- Attack rate: Participants must experience at least 1 investigator-confirmed HAE attack per 4 weeks during the run-in period to enter the lanadelumab treatment period.
- The participant (or the participants parent/legal authorized representative, if applicable) has provided written informed consent approved by the Institutional Review Board/Independent Ethics Committee (IRB/IEC).
- If the participant is an adult, be informed of the nature of the study and provide written informed consent before any study-specific procedures are performed or if the participant is a minor (ie, below the age of majority), have a parent/legally authorized representative who is informed of the nature of the study provide written informed consent (ie, permission) for the minor to participate in the study before any study-specific procedures are performed. Assent will be obtained from minor participants.
- Males, or non pregnant, non lactating females who are fertile and sexually active and who agree to be abstinent or agree to comply with the applicable contraceptive requirements of this protocol for the duration of the study, or females of non child bearing potential, defined as surgically sterile (status post hysterectomy, bilateral oophorectomy, or bilateral tubal ligation) or postmenopausal for at least 12 months.
- Agree to adhere to the protocol-defined schedule of assessments and procedures.
You may not qualify if:
- Concomitant diagnosis of another form of chronic, recurrent angioedema, such as acquired angioedema (AAE), HAE with normal C1-INH (also known as HAE Type 3), idiopathic angioedema, or recurrent angioedema associated with urticaria.
- Participation in a prior lanadelumab study.
- Dosing with investigational drug or exposure to an investigational device within 4 weeks prior to entering to screening.
- Exposure to angiotensin-converting enzyme (ACE) inhibitors or any estrogen-containing medications with systematic absorption (such as oral contraceptives or hormonal replacement therapy) within 4 weeks prior to screening.
- Exposure to androgens (eg, danazol, methyltestosterone, testosterone) within 2 weeks prior to entering the run-in period.
- Use of long-term prophylactic therapy for HAE (C1-INH, attenuated androgens, or anti-fibrinolytics) within 2 weeks prior to entering the run in period.
- Use of short-term prophylaxis for HAE 7 days prior to entering the run-in period. Short-term prophylaxis is defined as C1-INH, attenuated androgens, or anti-fibrinolytics used to avoid angioedema complications from medically indicated procedures.
- Any of the following liver function abnormalities: alanine aminotransferase (ALT) \>3x upper limit of normal, or aspartate aminotransferase (AST) \>3x upper limit of normal or bilirubin \>2x upper limit of normal (unless the bilirubin is a result of Gilbert's syndrome).
- Pregnancy or breast feeding.
- Participant has any condition that in the opinion of the investigator or sponsor, may compromise their safety or compliance, preclude successful conduct of the study, or interfere with interpretation of the results (eg, history of substance abuse, or dependence, significant preexisting illnesses or major comorbidity the investigator considers may confound the interpretation of the study results).
- Participant has a known hypersensitivity to the IP or its components.
