A total of 44 previously treated patients with severe hemophilia A (43 of whom were adolescents and adults) underwent a total of 14 major and 46 minor surgeries
All subjects received KOVALTRY® as bolus infusions
In the adolescent and adult subjects, initial KOVALTRY® doses administered ranged between 3000–5000 IU
Median total dose on the day of surgery was 107.5 IU/kg (range, 60–207 IU/kg)
Treatment with KOVALTRY® was assessed as good or excellent in all documented surgeries1
KOVALTRY® Antihemophilic Factor (Recombinant) is a recombinant human DNA sequence derived, full length Factor VIII concentrate indicated for use in adults and children with hemophilia A for:
On-demand treatment and control of bleeding episodes
Perioperative management of bleeding
Routine prophylaxis to reduce the frequency of bleeding episodes
KOVALTRY® is not indicated for the treatment of von Willebrand disease.
IMPORTANT SAFETY INFORMATION
KOVALTRY® is contraindicated in patients who have a history of hypersensitivity reactions to the active substance, to any of the excipients, or to mouse or hamster proteins.
Hypersensitivity reactions, including anaphylaxis, are possible with KOVALTRY®. Early signs of hypersensitivity reactions, which can progress to anaphylaxis, may include chest or throat tightness, dizziness, mild hypotension and nausea. Discontinue KOVALTRY® if symptoms occur and seek immediate emergency treatment.
KOVALTRY® may contain trace amounts of mouse and hamster proteins. Patients treated with this product may develop hypersensitivity to these non-human mammalian proteins.
Neutralizing antibody (inhibitor) formation can occur following administration of KOVALTRY®. Previously untreated patients (PUPs) are at greatest risk for inhibitor development with all Factor VIII products. Carefully monitor patients for the development of Factor VIII inhibitors, using appropriate clinical observations and laboratory tests. If expected plasma Factor VIII activity levels are not attained or if bleeding is not controlled as expected with administered dose, suspect the presence of an inhibitor.
Hemophilic patients with cardiovascular risk factors or diseases may be at the same risk to develop cardiovascular events as non-hemophilic patients when clotting has been normalized by treatment with Factor VIII.
Catheter-related infections may occur when KOVALTRY® is administered via central venous access devices (CVADs). These infections have not been associated with the product itself.
The most frequently reported adverse reactions in clinical trials (≥3%) were headache, pyrexia, and pruritus.
