Real safety is multidimensional
Important safety information
- The most serious adverse reactions are systemic hypersensitivity reactions and the development of hightiter inhibitors necessitating alternative treatments to AHF. The most common adverse reactions observed in clinical trials were:
- Inhibitor formation in previously untreated or minimally treated patients
- Skin-associated hypersensitivity reactions
- Infusion site reactions
- Central venous access device (CVAD) line-associated infections
Low Inhibitor Rates in clinical studies
- In clinical studies, 0% (0 of 72 patients) inhibitor formation observed in previously treated patients (PTPs)1*
- 15% (9 of 60 patients) inhibitor formation observed in previously untreated patients (PUPs) and minimally treated patients (MTPs)1†
- In the pediatric prophylaxis clinical trials, de novo inhibitor development was observed in 8 of 64 patients with negative baseline values (12.5%);
Two patients developed high-titer inhibitors and were withdrawn from the study.3

*No FVIII inhibitors developed in 72 who received Kogenate® FS, antihemophilic factor (recombinant), for up to 54 exposure months.
†In trials with PUPs and MTPs, 88% of patients (53 of 60) achieved 20 or more exposure days, and the incidence of inhibitor formation is consistent with that observed in other pediatric studies using FVIII products.2
‡ 2 patients developed high tier (>5 BU) inhibitors and were withdrawn from the study.3
