IXINITY provides predictable bleed control for your active, unpredictable life.
IXINITY® has an average incremental recovery of 98%.1 Higher recovery may allow lower doses.
Incremental Recovery: The increase in plasma concentration per IU/kg of factor administered.2 Plasma-derived factor products have an incremental recovery close to 1 or 100%.2,3
Selected Important Safety Information
Your body may form inhibitors to IXINITY. An inhibitor is part of the body's defense system. If you develop inhibitors, it may prevent IXINITY from working properly. Consult with your healthcare provider to make sure you are carefully monitored with blood tests for development of inhibitors to IXINITY.
How recovery impacts infusion dose.†
Hypothetical example: Keith weighs 155 lb (about 70 kg), and is looking for a 50% factor IX increase (correction).
Dose (IU) = body weight x desired factor IX increase x (1/recovery)1
The pharmacokinetics of IXINITY have been evaluated in 32 previously treated patients ≥12 years of age with severe to moderately severe hemophilia B.1
Ask your doctor to do an individual PK test to determine your recovery with IXINITY.
24-hour half-life for peak factor IX levels when you need them.
The average terminal half-life of IXINITY® is 24 hours.1
Individual half-life may vary.
Peak factor level: Point when the highest concentration of factor in the blood is reached.4 Matching peak factor level timing with peak activity level may help support an active lifestyle.
Terminal half-life: Time it takes for the drug’s activity to decrease by half after factor has been distributed throughout the body. The longer the terminal half-life, the longer factor is active in your system.4
50% of peak factor level remains after full day.
Individual response may vary; therefore, number of days between dosing may vary.
IXINITY® resolves most bleeds with 1 infusion.
In a clinical trial1*:
- 71% of bleeds resolved with 1 infusion
- Patients rated bleed control as excellent or good in 84% of all bleeds treated1 †
In a clinical trial, IXINITY was used in major surgeries1:
- Knee and elbow joint replacements
- Arthroscopic surgeries to remove inflamed joint tissue
- “Expected” or “less than expected” blood loss
- Zero transfusions during surgery
- Bleed control rated adequate or better than adequate at 12 and 24 hours post-surgery
IXINITY recovery is an average based on lab tests of patients in the clinical study.1 Because your actual recovery may be different, your dose may be different, too. Speak with your healthcare professional about the exact dose for you.
Description is not of an actual patient. Individual dose will vary. Patient with a baseline factor level of <1%.
The efficacy (n=68) and safety (n=77) of IXINITY has been evaluated in a prospective, open-label, uncontrolled, multicenter trial in which previously treated patients (PTPs) between 7 and 64 years of age received IXINITY in either a routine or on-demand regimen.1
