Bortezomib (Page 3 of 10)

2.8 Dosage in Patients with Hepatic Impairment

Do not adjust the starting dose for patients with mild hepatic impairment.
Start patients with moderate or severe hepatic impairment at a reduced dose of 0.7 mg/m2 per injection during the first cycle, and consider subsequent dose escalation to 1 mg/m2 or further dose reduction to 0.5 mg/m2 based on patient tolerance (see Table 6) [ see Use in Specific Populations (8.7),

Clinical Pharmacology (12.3)] .

Table 6: Recommended Starting Dose Modification for Bortezomib for Injection in Patients with Hepatic Impairment

Bilirubin Level SGOT (AST) Levels Modification of Starting Dose
Mild Less than or equal to 1 x ULN More than ULN None
More than 1x to 1.5x ULN Any None
Moderate More than 1.5x to 3x ULN Any Reduce bortezomib for injection to 0.7 mg/m2 in the first cycle. Consider dose escalation to1 mg/m2 or further dose reduction to 0.5 mg/m2 in subsequent cycles based on patient tolerability.
Severe More than 3x ULN Any

Abbreviations: SGOT = serum glutamic oxaloacetic transaminase; AST = aspartate aminotransferase; ULN = upper limit of the normal range.

2.9 Administration Precautions

The drug quantity contained in one vial (3.5 mg) may exceed the usual dose required. Caution should be used in calculating the dose to prevent overdose [see Dosage and Administration (2.10)].

When administered subcutaneously, sites for each injection (thigh or abdomen) should be rotated. New injections should be given at least one inch from an old site and never into areas where the site is tender, bruised, erythematous, or indurated.

If local injection site reactions occur following bortezomib for injection administration subcutaneously, a less concentrated bortezomib for injection solution (1 mg/mL instead of 2.5 mg/mL) may be administered subcutaneously [see Dosage and Administration (2.10)]. Alternatively, consider use of the intravenous route of administration [see Dosage and Administration (2.10)].
Bortezomib for injection is a hazardous drug. Follow applicable special handling and disposal procedures.1

2.10 Reconstitution/Preparation for Intravenous and Subcutaneous Administration

Use proper aseptic technique. Reconstitute only with 0.9% sodium chloride. The reconstituted product should be a clear and colorless solution.
Different volumes of 0.9% sodium chloride are used to reconstitute the product for the different routes of administration. The reconstituted concentration of bortezomib for subcutaneous administration (2.5 mg/mL) is greater than the reconstituted concentration of bortezomib for intravenous administration (1 mg/mL). Because each route of administration has a different reconstituted concentration, use caution when calculating the volume to be administered [see Dosage and Administration (2.9)]. For each 3.5 mg single-dose vial of bortezomib, reconstitute with the following volume of 0.9% sodium chloride based on route of administration (Table 7):

Table 7: Reconstitution Volumes and Final Concentration for Intravenous and Subcutaneous Administration

Route of Administration Bortezomib (mg/vial) Diluent (0.9% Sodium Chloride) Final Bortezomib Concentration (mg/mL)
Intravenous 3.5 mg 3.5 mL 1 mg/mL
Subcutaneous 3.5 mg 1.4 mL 2.5 mg/mL

Dose must be individualized to prevent overdosage. After determining patient body surface area (BSA) in square meters, use the following equations to calculate the total volume (mL) of reconstituted bortezomib for injection to be administered:

  • Intravenous Administration [1 mg/mL concentration ]

Bortezomib for injection dose (mg/m2) x patient BSA (m2)

______________________________________________ = Total bortezomib for injection volume (mL) to be administered

1 mg/mL

  • Subcutaneous Administration [2.5 mg/mL concentration]

Bortezomib for injection dose (mg/m2) x patient BSA (m2)

________________________________________________ = Total bortezomib for injection volume (mL) to be administered

2.5 mg/mL

Stickers that indicate the route of administration are provided with each bortezomib for injection vial. These stickers should be placed directly on the syringe of bortezomib for injection once bortezomib for injection is prepared to help alert practitioners of the correct route of administration for bortezomib for injection.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. If any discoloration or particulate matter is observed, the reconstituted product should not be used.
Unopened vials of bortezomib for injection are stable until the date indicated on the package when stored in the original package protected from light.
Bortezomib for injection contains no antimicrobial preservative. Administer reconstituted bortezomib for injection within eight hours of preparation. When reconstituted as directed, bortezomib for injection may be stored at 25ºC (77ºF). The reconstituted material may be stored in the original vial and/or the syringe prior to administration. The product may be stored for up to eight hours in a syringe; however, total storage time for the reconstituted material must not exceed eight hours when exposed to normal indoor lighting.


For injection: Each single-dose vial of bortezomib for injection contains 3.5 mg of bortezomib as a sterile white to off white lyophilized cake or powder for reconstitution and withdrawal of the appropriate individual patient dose [ see Dosage and Administration (2.10)].


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.


5.1 Peripheral Neuropathy

Bortezomib treatment causes a peripheral neuropathy that is predominantly sensory; however, cases of severe sensory and motor peripheral neuropathy have been reported. Patients with pre-existing symptoms (numbness, pain or a burning feeling in the feet or hands) and/or signs of peripheral neuropathy may experience worsening peripheral neuropathy (including ≥Grade 3) during treatment with bortezomib. Patients should be monitored for symptoms of neuropathy, such as a burning sensation, hyperesthesia, hypoesthesia, paresthesia, discomfort, neuropathic pain or weakness. In the Phase 3 relapsed multiple myeloma trial comparing bortezomib subcutaneous vs intravenous, the incidence of Grade ≥2 peripheral neuropathy was 24% for subcutaneous and 39% for intravenous. Grade ≥3 peripheral neuropathy occurred in 6% of patients in the subcutaneous treatment group, compared with 15% in the intravenous treatment group [see Adverse Reactions (6.1)]. Starting bortezomib subcutaneously may be considered for patients with pre-existing or at high risk of peripheral neuropathy.

Patients experiencing new or worsening peripheral neuropathy during bortezomib therapy may require a decrease in the dose and/or a less dose-intense schedule [see Dosage and Administration (2.7)]. In the bortezomib vs dexamethasone Phase 3 relapsed multiple myeloma study, improvement in or resolution of peripheral neuropathy was reported in 48% of patients with ≥Grade 2 peripheral neuropathy following dose adjustment or interruption. Improvement in or resolution of peripheral neuropathy was reported in 73% of patients who discontinued due to Grade 2 neuropathy or who had ≥Grade 3 peripheral neuropathy in the Phase 2 multiple myeloma studies. The long-term outcome of peripheral neuropathy has not been studied in mantle cell lymphoma.
