Factor IX Complex Intravenous Administration

Name: Factor IX Complex Intravenous Administration

Indications

BEBULIN is indicated for the prevention and control of bleeding episodes in adult patients with hemophilia B (congenital Factor IX deficiency or Christmas disease).

BEBULIN is not indicated for use in the treatment of Factor VII deficiency. No clinical studies have been conducted to show benefit from this product for treating deficiencies other than Factor IX deficiency.

Side effects

Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The following adverse reactions were reported in clinical studies with a previous formulation of BEBULIN:

Hypotension, Dizziness, Urticaria, Erythema, Pyrexia, and Chills.

The formation of inhibitor antibodies to Factor IX has been observed with the administration of BEBULIN.

Postmarketing Experience

Because postmarketing reporting of adverse reactions is voluntary and from a population of uncertain size, it is not always possible to reliably estimate the frequency of these reactions or establish a causal relationship to product exposure.

Table 2 lists the adverse reactions reported during postmarketing use of BEBULIN.

Table 2: Postmarketing Adverse Reactions

Blood and Lymphatic System Disorders Disseminated intravascular coagulation
Immune System Disorders Anaphylactic/Anaphylactoid reactions, Hypersensitivity
Nervous System Disorders Headache
Cardiac Disorders Tachycardia
Vascular Disorders Thromboembolic events (including Deep vein thrombosis, Pulmonary embolism, Thrombotic stroke), Flushing
Respiratory, Thoracic, and Mediastinal Disorders Dyspnea, Bronchospasm, Wheezing, Cough
Gastrointestinal Disorders Abdominal pain, Nausea
Skin and Subcutaneous Tissue Disorders Angioedema, Facial edema, Rash, Pruritus
Renal and Urinary Disorders Nephrotic syndrome (following attempted immune tolerance induction)
General Disorders and Administration Site Conditions Infusion site reactions, including Infusion site pain

In addition to reactions listed above, myocardial infarction has been identified in the published literature with other Factor IX products.

Clinical pharmacology

BEBULIN is a combination of vitamin K-dependent clotting factors (Factor IX, II, X) and found in normal plasma. The administration of BEBULIN provides an increase in plasma levels of Factor IX and can temporarily correct the coagulation defect of patients with Factor IX deficiency. Plasma levels of Factors II and X will also be increased. However, no clinical studies have been conducted to show benefit from this product for treating deficiencies other than Factor IX deficiency.

In vivo recovery of BEBULIN was determined using the former International Standard, WHO 72/32 and was found to be 53.3% ±9.6%, 57.5% ±21.8%, and 53.24% ±16.95%, respectively. In the same studies, using different methodologies, half-lives were determined to be 19.4 hrs ±3.8 hrs, 24.6 hrs ±3.2 hrs, and 19.97 hrs ±8.24 hrs, respectively.1
