ELOCTATE®—Powered by Fc Fusion


Fc Fusion MOE

ELOCTATE contains the Fc region of IgG11

• IgG1 allows ELOCTATE to extend its half-life by binding to the neonatal Fc receptor1

• IgG1 is a naturally occurring protein that has anti-inflammatory and immunomodulatory properties2,3

• The molecular mechanism behind the effects achieved by ELOCTATE is not
yet fully understood, including the interaction with cellular Fc receptors that
ELOCTATE may interact with2

ELOCTATE Fc Fusion MOE

Fc Fusion helps ELOCTATE stay in circulation through a natural pathway and does not accumulate.1,4

Fc=fragment crystallizable; FVIII=factor VIII;  IgG1=immunoglobin G1; MOE=mechanism of extension.

INDICATION

ELOCTATE® [Antihemophilic Factor (Recombinant), Fc Fusion Protein], is a recombinant DNA derived, antihemophilic factor indicated in adults and children with Hemophilia A (congenital Factor VIII deficiency) for: on-demand treatment and control of bleeding episodes, perioperative management of bleeding, and routine prophylaxis to reduce the frequency of bleeding episodes.

Limitation of Use
ELOCTATE is not indicated for the treatment of von Willebrand disease.

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS
ELOCTATE is contraindicated in patients who have had life-threatening hypersensitivity reactions to ELOCTATE or its excipients.

WARNINGS AND PRECAUTIONS

  • Hypersensitivity reactions have been reported with ELOCTATE. Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with Factor VIII replacement products. Immediately discontinue ELOCTATE and initiate appropriate treatment if hypersensitivity reactions occur.
  • Formation of neutralizing antibodies (inhibitors) to Factor VIII has been reported following administration of ELOCTATE. Patients using ELOCTATE should be monitored for the development of Factor VIII inhibitors. Clotting assays (e.g., one-stage) may be used to confirm that adequate Factor VIII levels have been achieved and maintained.
  • Hemophilic patients with cardiovascular risk factors or diseases may be at the same risk to develop cardiovascular events as non-hemophilic patients when clotting has been normalized by treatment with Factor VIII.
  • If a central venous access device (CVAD) is required, risk of CVAD-related complications including local infections, bacteremia, and catheter-site thrombosis should be considered.

ADVERSE REACTIONS
The most frequently occurring adverse reactions (incidence >0.5% of subjects) reported in previously treated patients (PTPs) clinical trials were arthralgia, malaise, myalgia, headache, and rash. The most frequently occurring adverse reactions (incidence ≥1.0% of subjects) reported in previously untreated patients (PUPs) clinical trials were Factor VIII inhibition, device-related thrombosis, and rash papular.
