Important Safety Information for IDELVION
IDELVION®, Coagulation Factor IX (Recombinant), Albumin Fusion Protein (rFIX-FP), is indicated in children and adults with hemophilia B (congenital Factor IX deficiency) for:
- On-demand treatment and control of bleeding episodes
- Perioperative management of bleeding
- Routine prophylaxis to reduce the frequency of bleeding episodes
IDELVION is not indicated for induction of immune tolerance in patients with hemophilia B.
IDELVION is contraindicated in patients who have had life-threatening hypersensitivity reactions to IDELVION or its components, including hamster proteins.
IDELVION is for intravenous use only. IDELVION can be self-administered or administered by a caregiver with training and approval from a healthcare provider or hemophilia treatment center. For pediatric patients, higher dose per kilogram body weight or more frequent dosing may be needed.
Hypersensitivity reactions have been reported. If patient shows symptoms of hypersensitivity reactions, including anaphylaxis, discontinue IDELVION and administer appropriate treatment.
The formation of neutralizing antibodies (inhibitors) to Factor IX has been reported with IDELVION. If expected Factor IX activity plasma levels are not attained or bleeding is not controlled with appropriate dose, perform an assay to measure Factor IX inhibitor concentration. Factor IX activity assay results may vary with the type of activated partial thromboplastin time reagent used.
Thromboembolism (eg, pulmonary embolism, venous thrombosis, and arterial thrombosis) can occur when using Factor IX-containing products. In addition, nephrotic syndrome has been reported following immune tolerance induction in hemophilia B patients with Factor IX inhibitors and a history of allergic reactions to Factor IX.
The most common adverse reactions (incidence ≥1%) reported in clinical trials were headache, dizziness, hypersensitivity, and rash.
