For the prophylaxis regimen to prevent or reduce frequency of bleeding episodes, RIXUBIS dosing of 40 to 60 IU per kg twice weekly may be used. Five dosage options will be available to provide the opportunity for patients to use a single vial to dose RIXUBIS. A BAXJECT II Needle-less Transfer device will be included in each package of RIXUBIS.Baxter was granted orphan-drug designation by the FDA as part of the RIXUBIS application, a special status given to a product that would address an unmet need for people with a rare disease or condition. Baxter expects to file for marketing authorization for RIXUBIS in the European Union later this year. About the Pivotal Study The approval is based on a pivotal Phase I/III prospective, open-label, uncontrolled, multicenter study that investigated the pharmacokinetics, efficacy and safety of RIXUBIS in 73 previously-treated patients (between 12 and 65 years of age) with severe (factor IX level <1 percent) or moderately severe (factor IX level ≤2 percent) hemophilia B. Patients received RIXUBIS either for prophylaxis and/or for the treatment of bleeding episodes on an on-demand basis, and were exposed to a factor IX-containing product on ≥150 days. Fifty-nine patients received RIXUBIS for prophylaxis twice-weekly, and 56 of them received treatment for a minimum of three months. An additional 14 patients received RIXUBIS for the treatment of bleeding episodes only, and had to have at least 12 documented bleeding episodes requiring treatment within 12 months prior to enrollment. The majority of patients taking RIXUBIS had arthropathy at screening (88 percent) and target joints (66 percent). Treatment was individualized based on the severity, cause and site of bleed and of the total 249 bleeding episodes, the majority (211; 84.7 percent) were treated with 1-2 infusions. About RIXUBIS RIXUBIS [Coagulation Factor IX (Recombinant)] is a recombinant factor IX (rFIX) protein for both routine prophylaxis and control of bleeding episodes in adults with hemophilia B. RIXUBIS is the first new rFIX approved to treat hemophilia B in more than 15 years and is the only rFIX approved by the FDA for both routine prophylaxis and control of bleeding episodes in this chronic condition.
Indications for RIXUBISRIXUBIS [Coagulation Factor IX (Recombinant)] is an antihemophilic factor indicated for:
- Control and prevention of bleeding episodes in adults with hemophilia B.
- Perioperative management in adults with hemophilia B.
- Routine prophylaxis to prevent or prevent or reduce the frequency of bleeding episodes in adults with hemophilia B.
- Known hypersensitivity to RIXUBIS or its excipients including hamster protein
- Disseminated intravascular coagulation (DIC)
- Signs of fibrinolysis
The following class adverse reactions have been seen with another recombinant factor IX: inadequate factor IX recovery, inhibitor development, anaphylaxis, angioedema, dyspnea, hypotension, and thrombosis.Please see the RIXUBIS full Prescribing Information at: www.baxter.com/downloads/healthcare_professionals/products/RIXUBIS_PI.pdf . About Hemophilia B Hemophilia B is the second most common type of hemophilia (also known as Christmas disease) and is the result of insufficient amounts of clotting factor IX, a naturally occurring protein in blood that controls bleeding. 1 Approximately 26,000 people worldwide, including more than 4,000 in the U.S., have been diagnosed with hemophilia B. 2 Hemophilia B is often a debilitating, chronic disease with complications that include bleeding episodes, hemophilic arthropathy (bleeding into a joint) and hospitalization. 3 About Baxter in Hemophilia Baxter has more than 60 years experience in hemophilia and has introduced a number of therapeutic firsts for hemophilia patients.
