Coagulation Factor Ix (recombinant)
Generic Name: coagulation factor ix (recombinant)
Brand Names:
Ixinity
11 DESCRIPTION IXINITY [coagulation factor IX (recombinant)] is a purified protein that has 415 amino acids. It has an amino acid sequence that is comparable to the Thr148 allelic form of plasma-derived factor IX. Coagulation factor IX (recombinant) is a single-chain glycoprotein with a molecular mass of about 55,000 Dalton that is secreted by a genetically engineered mammalian cell line derived from Chinese hamster ovary (CHO) cells.

Uses
1 INDICATIONS AND USAGE IXINITY, Coagulation Factor IX (Recombinant), is a human blood coagulation factor indicated in adults and children with hemophilia B for: On-demand treatment and control of bleeding episodes Perioperative management Routine prophylaxis to reduce the frequency of bleeding episodes IXINITY is not indicated for induction of immune tolerance in patients with hemophilia B [see Warnings and Precautions ( 5.3 ) ].
Dosage
2 DOSAGE AND ADMINISTRATION For intravenous use after reconstitution only. For intravenous use after reconstitution only. On-demand treatment and control of bleeding episodes and perioperative management of bleeding: Adolescents/Adults (≥ 12 years of age): One international unit (IU) of IXINITY per kg body weight increases the circulating activity of factor IX by 0.98 IU/dL. ( 2.1 ) Children (< 12 years of age): One international (IU) of IXINITY per kg body weight increases the circulating activity of factor IX by 0.79 IU/dL. ( 2.1 ) Initial dose: Required factor IX units (IU) = body weight (kg) x desired factor IX increase (% of normal or IU/dL) x reciprocal of observed recovery (IU/kg per IU/dL).
Side Effects
6 ADVERSE REACTIONS The most common adverse reaction (> 2%) reported in clinical trials was headache. The most common adverse reaction observed in > 2% of patients in clinical trials was headache ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Medexus Pharma, Inc. at 1-844-859-6675 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials 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.
Warnings
5 WARNINGS AND PRECAUTIONS Hypersensitivity reactions, including anaphylaxis has occurred. Should symptoms occur, discontinue IXINITY and administer appropriate treatment. Patients may also develop hypersensitivity to hamster (CHO) protein, which is present in trace amounts in the product ( 5.1 ) Development of neutralizing antibodies (inhibitors) to IXINITY may occur. 4 CONTRAINDICATIONS IXINITY is contraindicated in patients who have known hypersensitivity to IXINITY or its excipients, including hamster protein [see Warnings and Precautions (5.1) ]. Do not use in patients with known hypersensitivity to IXINITY or its excipients, including hamster protein ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary There are no data with IXINITY use in pregnant women to inform a drug-associated risk. Animal reproduction studies have not been conducted with IXINITY. In the U.S. general population, the estimated background risk of major birth defect and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Storage
16 HOW SUPPLIED/STORAGE AND HANDLING IXINITY is supplied as a lyophilized powder in single-dose glass vials containing the labeled amount of factor IX activity, expressed in international units (IU). The actual factor IX activity in IU is stated on the label of each vial.
