C1-INH therapy for patients with C1-INH deficiency

Most patients with HAE experience angioedema attacks because they lack functioning C1-INH. BERINERT replaces missing or dysfunctional C1-INH through an intravenous infusion, which quickly restores their C1-INH levels.

BERINERT addresses the problem of C1-INH deficiency by replacing missing or dysfunctional C1-INH

  • C1-INH regulates multiple pathways
  • Restoring C1-INH prevents bradykinin generation3
  • C1-INH decreases vascular permeability

BERINERT acts at multiple sites4

Complement system

C1-INH inactivates C1, thereby stopping the production of proteolytic fragments and inflammation-inducing complexes.

Fibrinolytic system

C1-INH inhibits plasmin, thus inhibiting fibrin degradation.


Kallikrein-kinin system

C1-INH prevents the conversion of prekallikrein to kallikrein—and the subsequent formation of bradykinin.

Coagulation cascade

C1-INH inhibits Factors XIIa and XIa.

Intravenous delivery provides quick uptake of C1-INH

A single dose of BERINERT IV provides a rapid increase in C1-INH levels*

*In a prospective, randomized, open-label, crossover study, 23 subjects with mild or moderate HAE received a single dose of BERINERT (1000 units) IV or SC during an attack-free interval.5
