Jivi vs. Eloctate - PK Comparison
Click to expand section.
Jivi® rFVIII levels remain elevated and sustained over time
- The pharmacokinetics (PK) of Jivi® were investigated in 29 severe hemophilia A patients (≥12 years of age) following a single 60 IU/kg dose
- Pharmacokinetics is the activity of drugs in the body over a period of time
PK was primarily measured by*
Jivi® is a PEGylated rFVIII with an extended half-life§ of 17.9 hours†
- IU, international units; kg, kilograms; PEG, polyethylene glycol; rFVIII, recombinant Factor VIII.
- Other PK parameters measured were maximum drug concentration in plasma after a single dose, mean residence time after an IV administration, and apparent volume of distribution at steady state.
- Clearance measured 1.63 mL/h/kg.
- Area under the curve measured 4060 IU*h/dL.
- Half-life is defined as the time it takes for the amount of a drug in the blood to decrease by one half.
- †With a single, 60 IU/kg dose.

Jivi® vs Eloctate® PK comparison
Jivi® vs Eloctate® PK Comparison
In the 17 patients (excluding the outlier), there were 3 statistically significant PK differences:
Compared with Eloctate®
Jivi® demonstrated more time before reaching minimum FVIII levels
Jivi® median time to minimum FVIII levels (compared to Eloctate®) in a population PK analysis (excluding the outlier patient, N=17)®
- PK, pharmacokinetics; FVIII, factor VIII.
- *Jivi® had a higher mean area under the curve (+25%).
- †Jivi® had lower mean clearance (-20%).
- ‡Jivi® had a longer mean half-life (+7%).
- §Adapted from Shah et al. A population PK model was developed based on data obtained by a one-stage assay to simulate time to reach FVIII thresholds of 1, 3, 5, and 10% FVIII.
Compared with Eloctate®, Jivi® demonstrated statistically significantly (N=17):
For N=18 patients, including the PK outlier patient, Jivi® demonstrated noninferiority to Eloctate® for AUC(0-tlast)*
Ask your doctor if the pharmacokinetic coverage of Jivi® is right for you.

- *Jivi® had a higher mean area under the curve (+25%).
- †Jivi® had lower mean clearance (-20%).
- ‡Jivi® had a longer mean half-life (+7%).
- §10%: 63 hours on Jivi® vs 52 hours on Eloctate®; 5%: 79 hours on Jivi® vs 67 hours on Eloctate®;
- 3%: 91 hours on Jivi® vs 79 hours on Eloctate®; 1%: 117 hours on Jivi® vs 104 hours on Eloctate®.

INDICATIONS
Jivi is an injectable medicine used to replace clotting factor (Factor VIII or antihemophilic factor) that is missing in people with hemophilia A.
Jivi is used to treat and control bleeding in previously treated adults and adolescents (12 years of age and older) with hemophilia A. Your healthcare provider may also give you Jivi when you have surgery. Jivi can reduce the number of bleeding episodes in adults and adolescents with hemophilia A when used regularly (prophylaxis).
Jivi is not for use in children below 12 years of age or in previously untreated patients.
Jivi is not used to treat von Willebrand disease.
IMPORTANT SAFETY INFORMATION
You should not use Jivi if you are allergic to rodents (like mice and hamsters) or to any ingredients in Jivi.
Tell your healthcare provider about all of your medical conditions that you have or had.
Tell your healthcare provider if you have been told that you have inhibitors to Factor VIII.
Allergic reactions may occur with Jivi. Call your healthcare provider right away and stop treatment if you get tightness of the chest or throat, dizziness, decrease in blood pressure, or nausea.
Allergic reactions to polyethylene glycol (PEG), a component of Jivi, are possible.
Your body can also make antibodies, called “inhibitors,” against Jivi, which may stop Jivi from working properly. Consult your healthcare provider to make sure you are carefully monitored with blood tests for the development of inhibitors to Factor VIII.
If your bleeding is not being controlled with your usual dose of Jivi, consult your doctor immediately. You may have developed Factor VIII inhibitors or antibodies to PEG and your doctor may carry out tests to confirm this.
The common side effects of Jivi are headache, cough, nausea, and fever.
These are not all the possible side effects with Jivi. Tell your healthcare provider about any side effect that bothers you or that does not go away.
For additional important risk and use information, please see the full Prescribing Information.
