Safety Study in Subjects ≥ 12 Years of Age With Hereditary Angioedema Switching to Garadacimab

CompletedPhase 4

Sponsor: CSL Behring

Conditions: Hereditary Angioedema

Interventions: Garadacimab

Countries: United States, Canada, Germany

This study is designed to evaluate the safety after switching to garadacimab from another prophylactic hereditary angioedema (HAE) treatment (marketed kallikrein \[KK\] inhibitor or plasma-derived C1-esterase inhibitor \[pdC1INH\]prophylactic) when administered once monthly for approximately 3 months in participants aged greater than or equal to (\>=) 12 years with HAE.

Eligibility overview

Sex: ALL

Age: 12 Years to —

Healthy volunteers: No

Study type: INTERVENTIONAL

Eligibility criteria

Inclusion Criteria:

* Aged \>= 12 years at the time of providing written informed consent / assent.
* Have a history of response to on-demand HAE treatment for the treatment of acute HAE attacks.
* Documented laboratory diagnosis in medical records of C1-esterase inhibitor hereditary angioedema (HAE-C1INH) type 1 or type 2:
* Documented clinical history consistent with HAE (subcutaneous or mucosal, nonpruritic swelling episodes without accompanying urticaria),
* C1-esterase inhibitor (C1INH) antigen concentration or functional activity less than (\<) 50% of normal as documented in the participant's medical record, or
* C4-antigen concentration below the lower limit of the reference range as documented in the participant's medical record.
* For HAE-nC1INH: Documented clinical history consistent with HAE (subcutaneous or mucosal, nonpruritic swelling episodes without accompanying urticaria); an HAE-associated FXII gene mutation (eg, FXII point mutation Thr328Lys or Thr328Arg, or deletion of 72 base pairs \[c.971\_1018 + 24del72\], or duplication of 18 base pairs \[c.892-909dup\]), as documented in the participant's medical record, OR an HAE-associated plasminogen gene mutation (PLG) gene mutation (eg, PLG point mutation Lys330Glu), as documented in the participant's medical record; C1INH antigen concentration or functional activity 70 to 120% of the normal level, as documented in the participant's medical record.
* Use of lanadelumab, berotralstat, or pdC1INH for the prophylactic treatment of HAE and be on a stable (consistent) dose / regimen of such medication for at least 3 months prior to Screening.

Exclusion Criteria:

* Concomitant diagnosis of another form of angioedema, such as idiopathic or acquired angioedema or recurrent angioedema associated with urticaria.
* Use of androgens, antifibrinolytics, or investigational products (other than garadacimab) for routine prophylaxis against HAE attacks.
* Known or suspected hypersensitivity to monoclonal antibody therapy or hypersensitivity to the active substance (garadacimab) or to any of the excipients.
