Finding a treatment that works for you is important
From prophylaxis in adults and children (0-16 years), to helping to stop bleeds in adults and children on demand, you need a hemophilia A treatment that works for you. Click on the table below to learn more about the efficacy of Kogenate® FS Antihemophilic Factor (Recombinant).
15.2x Fewer Bleeds with Prophylaxis1
In a clinical study measuring the results of Kogenate® FS as on-demand treatment versus prophylaxis (regular use) in previously treated adults, routine prophylactic treatment was proven to reduce the frequency of bleeds regardless of age, presence or absence of target joints, and bleeding history.1

With prophylaxis 94% Reduction in average number of bleeds per year
Adult prophylaxis study design1,2:
- 84 previously treated males with severe hemophilia A
- Aged 15 to 50 years
- People received Kogenate FS either 3 times/week or on demand after a bleed
- Primary endpoint was bleeding frequency
- Bleeding frequency was analyzed after a median follow-up period of 1.4 years

- You should not use Kogenate FS if you are allergic to rodents (like mice and hamsters) or are allergic to any ingredients in Kogenate FS.
- Tell your healthcare provider if you have been told you have heart disease or are at risk for heart disease.

Selected Safety Information
- Your body can make antibodies, called "inhibitors," against Kogenate FS, which may stop Kogenate FS from working properly. Consult with your healthcare provider to make sure you are carefully monitored with blood tests for the development of inhibitors to factor VIII.
Eight times fewer bleeds
Children using Kogenate FS as a prophylaxis treatment saw eight times fewer joint bleeds per year compared with enhanced on-demand treatment.1,4
Over 8x fewer joint bleeds per patient per year1
The average rate of index joint bleeds for subjects on on-demand therapy was 4.89 bleeds per year, versus 0.63 bleeds per year in the prophylaxis group.
Study description:
A total of 65 boys <30 months of age with severe hemophilia A (FVIII level ≤2 IU/dL) with ≤2 bleeds into each index joint and normal baseline joint imaging were observed for up to 5.5 years in a multicenter, open-label, prospective, randomized, controlled clinical study.
Patients received Kogenate FS either 25 IU/kg every other day (primary prophylaxis, n=32) or at least 3 doses totaling a minimum of 80 IU/kg at the time of a bleeding episode (enhanced episodic, n=33).
Joint damage was evaluated by MRI or radiography, and the frequency of bleeding episodes was assessed.
Safety in routine prophylaxis
- Overall, 12.5% (8 of 64) of study patients developed any level of inhibitors over the 5.5-year study.1
- Two patients developed high-titer inhibitors and were withdrawn from the study.1,4
- Previously Untreated Patients Inhibitor Registry Data
Post marketing registries in previously untreated patients taking Kogenate FS have shown inhibitor development rates of 31-50% which is comparable to previously-reported inhibitor rates for FVIII products. Some of these registries showed a trend towards an increased risk of inhibitor development in PUPs taking Kogenate FS, as compared to another rFVIII product.1 - There were no life-threatening bleeds* in routine prophylaxis group (0 of 32 patients) compared with approximately 10% (3 of 33) in the episodic group. 1,4
- Most adverse events were associated with central venous access, and there were no statistically significant differences between the two study groups. 1,4
A life-threatening bleed is a major hemorrhage or loss of blood, such as an intracranial or gastrointestinal bleed, which may result in death.
Selected Safety Information

Proven results
Joint health is important for children living with hemophilia A. In one clinical study, 93% (25 of 27) of children with no pre-existing joint damage who were treated with Kogenate® or Kogenate® FS for routine prophylaxis up to 5.5 years had no joint damage as measured by magnetic resonance imaging (MRI), compared with 55% (16 of 29) of children given on-demand treatment with Kogenate or Kogenate FS.1,4
The difference between the 2 groups was statistically significant when using MRI but not when using x-ray alone.1
9 out of 10
children on routine prophylaxis experienced no joint damage, as measured by MRI.4
Joint Outcome Study (JOS) study description: A total of 65 boys aged 0 to 2.5 years at the beginning of the study, with severe hemophilia A (FVIII level ≤2 IU/dL) and with ≤2 bleeds into each index joint and normal baseline joint imaging were observed for up to 5.5 years in a multicenter, open-label, prospective, randomized, controlled clinical study. Patients received either 25 IU/kg every other day (routine prophylaxis; 32 people) or at least 3 doses totaling a minimum of 80 IU/kg at the time of a bleeding episode (enhanced episodic; 33 people). Joint damage was evaluated by MRI or radiography, and the frequency of bleeding episodes was assessed.1,4
Selected Safety Information
- You should not use Kogenate FS if you are allergic to rodents (like mice and hamsters) or are allergic to any ingredients in Kogenate FS.
- Tell your healthcare provider if you have been told you have heart disease or are at risk for heart disease.
- You could have an allergic reaction to Kogenate FS. Call your healthcare provider right away and stop treatment if you get rash or hives, itching, tightness of the chest or throat, difficulty breathing, light-headed, dizziness, nausea or a decrease in blood pressure.

Inhibitor rates
Your body can make antibodies, called “inhibitors,” against factor VIII products including Kogenate FS, which may stop factor VIII from working properly. The inhibitor rates for Kogenate FS have been measured in several studies.
