Table: Post Marketing Experience MedDRA System Preferred Term Organ Class Immune system Hypersensitivity (including anaphylactic shock, disorders flushing, urticaria, rash, angioedema) Vascular disorders Thromboembolic events (including hepatic artery thrombosis, myocardial infarction, cerebral infarction, intestinal infarction, intracardiac thrombus, peripheral ischemia, portal vein thrombosis, myocardial ischemia, renal artery thrombosis) DRUG INTERACTIONS: Avoid simultaneous use of activated prothrombin complex concentrates or prothrombin complex concentrates. The risk of a potential interaction between NovoSeven ® RT and coagulation factor concentrates has not been adequately evaluated in preclinical or clinical studies. Do not mix NovoSeven ® RT with infusion solutions. Thrombosis may occur if NovoSeven ® RT is administered concomitantly with Coagulation Factor XIII. USE IN SPECIFIC POPULATIONS: Pregnancy: Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. NovoSeven ® RT should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Treatment of rats and rabbits with NovoSeven ® in reproduction studies has been associated with mortality at doses up to 6 mg per kg body weight and 5 mg per kg body weight respectively. At 6 mg per kg body weight in rats, the abortion rate was 0 out of 25 litters; in rabbits at 5 mg per kg body weight, the abortion rate was 2 out of 25 litters. Twenty-three out of 25 female rats given 6 mg per kg body weight of NovoSeven® gave birth successfully, however, two of the 23 litters died during the early period of lactation. No evidence of teratogenicity was observed after dosing with NovoSeven ®. Labor and Delivery: There are no adequate and well-controlled studies in labor, delivery, and postpartum periods. NovoSeven® RT has caused thrombosis when used to control post-partum hemorrhage. Nursing Mothers: It is not known whether NovoSeven ® RT is excreted in human milk. Because many drugs are excreted in human milk, and because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use: Clinical trials enrolling pediatric patients were conducted with dosing determined according to body weight and not according to age. Hemophilia A or B with Inhibitors: During the investigational phase of product development NovoSeven ® was used in 16 children aged 0 to <2 years for 151 bleeding episodes, 27 children aged 2 to <6 years for 140 bleeding episodes, 43 children aged 6 to <12 for 375 bleeding episodes and 30 children aged 12 to 16 years for 446 bleeding episodes. In a double-blind, randomized comparison trial of two dose levels of NovoSeven ® in the treatment of joint, muscle and mucocutaneous hemorrhages in hemophilia A and B patients with and without inhibitors 20 children aged 0 to <12 and 8 children aged 12 to 16 were treated with NovoSeven ® in doses of 35 or 70 micrograms per kg dose. Treatment was assessed as effective (definite relief of pain/tenderness as reported by the patient and/or a measureable decrease of the size of the hemorrhage and/or arrest of bleeding within 8 hours [rated as excellent = 51%], within 8-14 hours [rated as effective = 18%] or after 14 hours [rated as partially effective = 25%]) in 94% of the patients. NovoSeven® was used in two trials in surgery. In a dose comparison 22 children aged 0 to 16 years were treated with NovoSeven ®. Effective intraoperative hemostasis (defined as bleeding that had stopped completely or had decreased substantially [rated as effective = 86%] or bleeding that was reduced but continued [rated as partially effective = 9%]) was achieved in 21/22 (95%) patients. Effective hemostasis was achieved in 10/10 (100%) patients in the 90 mcg/kg dose group and 10/12 (83%) in the 35 mcg/kg dose group at 48 hours; effective hemostasis was achieved in 10/10 (100%) in the 90 mcg/kg dose group and 9/12 (75%) in the 35 mcg/kg dose group at 5 days. In the surgery trial comparing bolus (BI) and continuous infusion (CI) 6 children aged 10 to 15 years participated, 3 in each group. Both regimens were 100% effective (defined as bleeding has stopped completely, or decreased substantially) intra-operatively, through the first 24 hours and at day 5. At the end of the study period (Postoperative day 10 or discontinuation of therapy) hemostasis in two patients in the BI group was rated effective and hemostasis in one patient was rated as ineffective (defined as bleeding is the same or has worsened). Hemostasis in all three
