A Study of Lanadelumab in Teenagers and Adults With Hereditary Angioedema (HAE) in Argentina

An adverse event (AE) is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. Percentage of participants with AESIs such as hypersensitivity, immunogenicity, liver toxicity, and embryo-fetal toxicity will be reported.

An AE is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. Serious AE is any untoward medical occurrence (whether considered to be related to study assigned treatment or not) that at any dose resulted in death, is life-threatening event, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, results in a congenital abnormality/birth defect, or was an important medical event. AEs including both serious and non-serious adverse events will be reported.

HAE attack is defined as a discrete episode during which the participant progressed from no angioedema to symptoms of angioedema based on investigator judgement. In general, the event must have symptoms or signs consistent with an attack in greater than or equal to (>=) 1 of the typical locations (peripheral angioedema; abdominal angioedema; laryngeal/tongue angioedema). Monthly mean rate of investigator confirmed HAE attacks with assessments at Weeks 12 and 24 will be reported.

The overall severity of attack will be determined by the investigator using following definitions: mild (transient or mild discomfort), moderate (mild to moderate limitation in activity), severe (marked limitation in activity). Monthly mean rate of investigator confirmed moderate or severe HAE attacks with assessments at Weeks 12 and 24 will be reported.

HAE attack is defined as a discrete episode during which the participant progressed from no angioedema to symptoms of angioedema based on investigator judgement. In general, the event must have symptoms or signs consistent with an attack in >=1 of the typical locations (peripheral angioedema; abdominal angioedema; laryngeal/tongue angioedema). Monthly mean rate of investigator confirmed HAE attacks requiring acute treatment with assessments at Weeks 12 and 24 will be reported.

A participant will be considered as attack free during an efficacy evaluation period if the participant has no investigator-confirmed HAE attacks during treatment period. HAE attack is defined as a discrete episode during which the participant progressed from no angioedema to symptoms of angioedema based on investigator judgement. In general, the event must have symptoms or signs consistent with an attack in >=1 of the typical locations (peripheral angioedema; abdominal angioedema; laryngeal/tongue angioedema). Percentage of participants who are attack free with assessments at 12 and 24 weeks will be reported.
