Coagulation Factor IX (Human)
Monoclonal Antibody Purified
Coagulation Factor IX (Human), Mononine® (coagulation factor ix human) , is a sterile, stable, lyophilized concentrate of Factor IX prepared from pooled human plasma and is intended for use in therapy of Factor IX deficiency, known as Hemophilia B or Christmas disease. Mononine® (coagulation factor ix human) is purified of extraneous plasma-derived proteins, including Factors II, VII and X, by use of immunoaffinity chromatography. A murine monoclonal antibody to Factor IX is used as an affinity ligand to isolate Factor IX from the source material. Factor IX is then dissociated from the mon-oclonal antibody, recovered, purified further, formulated and provided as a sterile, lyophilized powder. The immunoaffinity protocol utilized results in a highly pure Factor IX preparation. It shows predominantly a single component by SDS polyacrylamide electrophoretic evaluation and has a specific activity of not less than 190 Factor IX units per mg total protein.
An investigational NAT for HBV was also performed on all Source Plasma used in the manufacture of this product and found to be nonreactive (negative). The aim of the HBV test is to detect low levels of viral mate-rial, however, the significance of a nonreactive (negative) result has not been established.
This concentrate has been processed by monoclonal antibody immunoaffinity chromatography during its manufacture, which has been shown to be capable of reducing the risk of viral transmission. Additionally, a chemical treatment protocol and two sequential ultrafiltration steps used in its manufacture have also been shown to be capable of significant virus reductions. However, no procedure has been shown to be totally effective in removing the risk of viral infectivity from coagulation factor concentrates (see CLINICAL PHARMACOLOGY and WARNINGS).
Mononine® (coagulation factor ix human) is a highly purified preparation of Factor IX. When stored as directed, it will maintain its labeled potency for the period indicated on the container label.
Each vial contains the labeled amount of Factor IX activity expressed in International Units (IU). One IU represents the activity of Factor IX present in 1 mL of normal, pooled plasma. When reconstituted as recommended, the resulting solution is a clear, colorless, isotonic preparation of neutral pH, containing approximately 100 times the Factor IX potency found in an equal volume of plasma. Each mL of the reconstituted concentrate contains approximately 100 IU of Factor IX and non-detectable levels of Factors II, VII and X ( < 0.0025 IU per Factor IX unit using standard coagulation assays). Each vial also contains histidine (approx. 10mM), sodium chloride (approx. 0.066M), mannitol (approx. 3%) and polysorbate 80 (approx. 0.0075%). Hydrochloric acid and/or sodium hydroxide may have been used to adjust pH. Mononine® (coagulation factor ix human) also contains trace amounts ( ≤ 50 ng mouse protein/100 Factor IX activity units) of the murine monoclonal antibody used in its purification (see CLINICAL PHARMACOLOGY).
Mononine (coagulation factor ix human) ® is to be administered only intravenously.
What are the possible side effects of coagulation factor IX (Alphanine SD, Benefix, Mononine)?
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have any of these serious side effects:
- fever or chills;
- continued bleeding after treatment;
- feeling like you might pass out;
- sudden numbness or weakness, especially on one side of the body;
- sudden headache, confusion, problems with vision, speech, or balance; or
- swelling in your feet or ankles, weight...
