Posología
2 DOSAGE AND ADMINISTRATION • For subcutaneous or intravenous use only. Each route of administration has a different reconstituted concentration. Exercise caution when calculating the volume to be administered. ( 2.1 , 2.10 ) • The recommended starting dose of bortezomib for injection is 1.3 mg/m 2 administered either as a 3 to 5 second bolus intravenous injection or subcutaneous injection. ( 2.2 , 2.4 , 2.6 ) • Retreatment for Multiple Myeloma: May retreat starting at the last tolerated dose. ( 2.6 ) • Hepatic Impairment: Use a lower starting dose for patients with moderate or severe hepatic impairment. ( 2.8 ) • Dose must be individualized to prevent overdose. ( 2.10 ) 2.1 Important Dosing Guidelines Bortezomib for injection is for intravenous or subcutaneous use only. Do not administer bortezomib for injection by any other route. Because each route of administration has a different reconstituted concentration, use caution when calculating the volume to be administered. The recommended starting dose of bortezomib for injection is 1.3 mg/m 2 . Bortezomib for injection is administered intravenously at a concentration of 1 mg/mL, or subcutaneously at a concentration of 2.5 mg/mL [see Dosage and Administration ( 2.10 )]. Bortezomib for injection retreatment may be considered for patients with multiple myeloma who had previously responded to treatment with bortezomib for injection and who have relapsed at least six months after completing prior bortezomib for injection treatment. Treatment may be started at the last tolerated dose [see Dosage and Administration ( 2.6 )]. When administered intravenously, administer bortezomib for injection as a 3 to 5 second bolus intravenous injection. 2.2 Dosage in Previously Untreated Multiple Myeloma Bortezomib for injection is administered in combination with oral melphalan and oral prednisone for 9, six week treatment cycles as shown in Table 1 . In Cycles 1 to 4, bortezomib for injection is administered twice weekly (Days 1, 4, 8, 11, 22, 25, 29 and 32). In Cycles 5 to 9, bortezomib for injection is administered once weekly (Days 1, 8, 22 and 29). At least 72 hours should elapse between consecutive doses of bortezomib for injection.

Contraindicaciones
4 CONTRAINDICATIONS Bortezomib is contraindicated in patients with hypersensitivity (not including local reactions) to bortezomib, boron, or mannitol. Reactions have included anaphylactic reactions [see Adverse Reactions ( 6.1 )]. Bortezomib is contraindicated for intrathecal administration. Fatal events have occurred with intrathecal administration of bortezomib. • Patients with hypersensitivity (not including local reactions) to bortezomib, boron, or mannitol, including anaphylactic reactions. ( 4 ) • Contraindicated for intrathecal administration. ( 4 )

8.1 Pregnancy Risk Summary Based on its mechanism of action [see Clinical Pharmacology ( 12.1 )] and findings in animals, bortezomib can cause fetal harm when administered to a pregnant woman. There are no studies with the use of bortezomib in pregnant women to inform drug-associated risks. Bortezomib caused embryo-fetal lethality in rabbits at doses lower than the clinical dose (see Data) . Advise pregnant women of the potential risk to the fetus. Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Bortezomib was not teratogenic in nonclinical developmental toxicity studies in rats and rabbits at the highest dose tested (0.075 mg/kg; 0.5 mg/m 2 in the rat and 0.05 mg/kg; 0.6 mg/m 2 in the rabbit) when administered during organogenesis. These dosages are approximately 0.5 times the clinical dose of 1.3 mg/m 2 based on body surface area. Bortezomib caused embryo-fetal lethality in rabbits at doses lower than the clinical dose (approximately 0.5 times the clinical dose of 1.3 mg/m 2 based on body surface area). Pregnant rabbits given bortezomib during organogenesis at a dose of 0.05 mg/kg (0.6 mg/m 2 ) experienced significant pos

Summary of Clinical Trial in Patients with Previously Untreated Multiple Myeloma Table 9 describes safety data from 340 patients with previously untreated multiple myeloma who received bortezomib (1.3 mg/m 2 ) administered intravenously in combination with melphalan (9 mg/m 2 ) and prednisone (60 mg/m 2 ) in a prospective randomized study. The safety profile of bortezomib in combination with melphalan/prednisone is consistent with the known safety profiles of both bortezomib and melphalan/prednisone.
