Antihemophilic factor human

HEMOFIL M is indicated in hemophilia A (classical hemophilia) for the prevention and control of hemorrhagic episodes. HEMOFIL M is not indicated in von Willebrand's disease.

For intravenous use only. The expected in vivo peak AHF level, expressed as IU/dL of plasma or % (percent) of normal, can be calculated by multiplying the dose administered per kg body weight (IU/kg) by two. This calculation is based on the clinical finding by Abildgaard, et al, 2 which is supported by data from the collaborative study of in vivo recovery and survival with 15 different lots of HEMOFIL M on 56 hemophiliacs that demonstrated a mean peak recovery point above the mean pre-infusion baseline of about

HEMOFIL M is contraindicated in patients with a known hypersensitivity to the active substance, to excipients, or to mouse proteins.

Hypersensitivity Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with HEMOFIL M and have been manifested by bronchospasm, dyspnea, hypotension, chest pain, facial edema, urticaria, rash, flushing, pruritus, and nausea. Neutralizing Antibodies The development of neutralizing antibodies (inhibitors) to Factor VIII is a known complication of the treatment of patients with Hemophilia A. Inhibitors have predominantly been reported in previously untreated patients. The risk of developing inhibitors is correlated to the extent of exposure to Factor VIII, the risk being highest within the first 20 exposure days, and to other genetic and environmental factors.

Adverse Reactions from Clinical Trials The adverse reactions presented in this section have been identified based on clinical trial experience with HEMOFIL M in patients previously treated with other Factor VIII concentrates or blood products (N = 74), and previously untreated patients (PUPs, N = 50). Clinical Trial Adverse Reactions System Organ Class (SOC) Preferred MedDRA Term Number of Cases (Frequency Percentage) BLOOD AND LYMPHATIC SYSTEM DISORDERS Factor VIII inhibition 3 (5.7%) In a study that included 43 evaluable PUPs and 10 minimally treated patients (MTPs), i.e., patients with a single exposure to other Factor VIII concentrates or blood products, 3 of the total of 53 patients (5.7%) developed an inhibitor while on study.

HEMOFIL M can be stored at 2°C to 8°C (36°F to 46°F) or at room temperature, not to exceed 30°C (86°F), until expiration date noted on the package. Do not freeze.
