    For information concerning rituximab, cyclophosphamide, doxorubicin and prednisone, see manufacturer's prescribing information.

    2.6 Dosage and Dose Modifications for Relapsed Multiple Myeloma and Relapsed Mantle Cell Lymphoma

    Bortezomib for Injection (1.3 mg/m 2/dose) is administered twice weekly for two weeks (Days 1, 4, 8, and 11) followed by a ten day rest period (Days 12 to 21). For extended therapy of more than eight cycles, Bortezomib for Injection may be administered on the standard schedule or, for relapsed multiple myeloma, on a maintenance schedule of once weekly for four weeks (Days 1, 8, 15, and 22) followed by a 13 day rest period (Days 23 to 35) [see Clinical Studies (14)] . At least 72 hours should elapse between consecutive doses of Bortezomib for Injection.

    Patients with multiple myeloma who have previously responded to treatment with Bortezomib for Injection (either alone or in combination) and who have relapsed at least six months after their prior Bortezomib for Injection therapy may be started on Bortezomib for Injection at the last tolerated dose. Retreated patients are administered Bortezomib for Injection twice weekly (Days 1, 4, 8, and 11) every three weeks for a maximum of eight cycles. At least 72 hours should elapse between consecutive doses of Bortezomib for Injection. Bortezomib for Injection may be administered either as a single agent or in combination with dexamethasone [see Clinical Studies (14.1)] .

    Bortezomib for Injection therapy should be withheld at the onset of any Grade 3 nonhematological or Grade 4 hematological toxicities excluding neuropathy as discussed below [see Warnings and Precautions (5)] . Once the symptoms of the toxicity have resolved, Bortezomib for Injection therapy may be reinitiated at a 25% reduced dose (1.3 mg/m 2/dose reduced to 1 mg/m 2/dose; 1 mg/m 2/dose reduced to 0.7 mg/m 2/dose).

    For dose modifications guidelines for peripheral neuropathy, see section 2.7.

    2.7 Dose Modifications for Peripheral Neuropathy

    Starting Bortezomib for Injection subcutaneously may be considered for patients with pre-existing or at high risk of peripheral neuropathy. Patients with pre-existing severe neuropathy should be treated with Bortezomib for Injection only after careful risk-benefit assessment.

    Patients experiencing new or worsening peripheral neuropathy during Bortezomib for Injection therapy may require a decrease in the dose and/or a less dose-intense schedule.

    For dose or schedule modification guidelines for patients who experience Bortezomib for Injection-related neuropathic pain and/or peripheral neuropathy, see Table 5.

    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) :

    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/m 2) x patient BSA (m 2)     =    Total Bortezomib for Injection volume (mL) to be administered
                                                      1 mg/mL

    • Subcutaneous Administration [2.5 mg/mL concentration]

              Bortezomib for Injection dose (mg/m 2) x patient BSA (m 2)     =    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.

    Stability
    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.

    Discard unused portion.

  • 3 DOSAGE FORMS AND STRENGTHS

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

  • 4 CONTRAINDICATIONS

    Bortezomib for Injection 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 for Injection is contraindicated for intrathecal administration. Fatal events have occurred with intrathecal administration of Bortezomib for Injection.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Peripheral Neuropathy

    Bortezomib for Injection 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 for Injection. 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 for Injection 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 for Injection 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 for Injection therapy may require a decrease in the dose and/or a less dose-intense schedule [see Dosage and Administration (2.7)] . In the Bortezomib for Injection 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.

    5.2 Hypotension

    The incidence of hypotension (postural, orthostatic, and hypotension NOS) was 8% [see Adverse Reactions (6.1)] . These events are observed throughout therapy. Patients with a history of syncope, patients receiving medications known to be associated with hypotension, and patients who are dehydrated may be at increased risk of hypotension. Management of orthostatic/postural hypotension may include adjustment of antihypertensive medications, hydration, and administration of mineralocorticoids and/or sympathomimetics.

    5.3 Cardiac Toxicity

    Acute development or exacerbation of congestive heart failure and new onset of decreased left ventricular ejection fraction have occurred during Bortezomib for Injection therapy, including reports in patients with no risk factors for decreased left ventricular ejection fraction [see Adverse Reactions (6.1)] . Patients with risk factors for, or existing heart disease should be frequently monitored. In the relapsed multiple myeloma study of Bortezomib for Injection vs dexamethasone, the incidence of any treatment-related cardiac disorder was 8% and 5% in the Bortezomib for Injection and dexamethasone groups, respectively. The incidence of adverse reactions suggestive of heart failure (acute pulmonary edema, pulmonary edema, cardiac failure, congestive cardiac failure, cardiogenic shock) was ≤1% for each individual reaction in the Bortezomib for Injection group. In the dexamethasone group the incidence was ≤1% for cardiac failure and congestive cardiac failure; there were no reported reactions of acute pulmonary edema, pulmonary edema, or cardiogenic shock. There have been isolated cases of QT-interval prolongation in clinical studies; causality has not been established.

    5.4 Pulmonary Toxicity

    Acute Respiratory Distress Syndrome (ARDS) and acute diffuse infiltrative pulmonary disease of unknown etiology such as pneumonitis, interstitial pneumonia, lung infiltration have occurred in patients receiving Bortezomib for Injection. Some of these events have been fatal.

    In a clinical trial, the first two patients given high-dose cytarabine (2 g/m 2per day) by continuous infusion with daunorubicin and Bortezomib for Injection for relapsed acute myelogenous leukemia died of ARDS early in the course of therapy.

    There have been reports of pulmonary hypertension associated with Bortezomib for Injection administration in the absence of left heart failure or significant pulmonary disease.

    In the event of new or worsening cardiopulmonary symptoms, consider interrupting Bortezomib for Injection until a prompt and comprehensive diagnostic evaluation is conducted.

    5.5 Posterior Reversible Encephalopathy Syndrome (PRES)

    Posterior Reversible Encephalopathy Syndrome (PRES; formerly termed Reversible Posterior Leukoencephalopathy Syndrome (RPLS)) has occurred in patients receiving Bortezomib for Injection. PRES is a rare, reversible, neurological disorder which can present with seizure, hypertension, headache, lethargy, confusion, blindness, and other visual and neurological disturbances. Brain imaging, preferably MRI (Magnetic Resonance Imaging), is used to confirm the diagnosis. In patients developing PRES, discontinue Bortezomib for Injection. The safety of reinitiating Bortezomib for Injection therapy in patients previously experiencing PRES is not known.

    5.6 Gastrointestinal Toxicity

    Bortezomib for Injection treatment can cause nausea, diarrhea, constipation, and vomiting [see Adverse Reactions (6.1)] sometimes requiring use of antiemetic and antidiarrheal medications. Ileus can occur. Fluid and electrolyte replacement should be administered to prevent dehydration. Interrupt Bortezomib for Injection for severe symptoms.

    5.7 Thrombocytopenia/Neutropenia

    Bortezomib for Injection is associated with thrombocytopenia and neutropenia that follow a cyclical pattern with nadirs occurring following the last dose of each cycle and typically recovering prior to initiation of the subsequent cycle. The cyclical pattern of platelet and neutrophil decreases and recovery remain consistent in the studies of multiple myeloma and mantle cell lymphoma, with no evidence of cumulative thrombocytopenia or neutropenia in the treatment regimens studied.

    Monitor complete blood counts (CBC) frequently during treatment with Bortezomib for Injection. Measure platelet counts prior to each dose of Bortezomib for Injection. Adjust dose/schedule for thrombocytopenia [see Dosage and Administration (2.6)] . Gastrointestinal and intracerebral hemorrhage has occurred during thrombocytopenia in association with Bortezomib for Injection. Support with transfusions and supportive care, according to published guidelines.

    In the single agent, relapsed multiple myeloma study of Bortezomib for Injection vs dexamethasone, the mean platelet count nadir measured was approximately 40% of baseline. The severity of thrombocytopenia related to pretreatment platelet count is shown in Table 8. The incidence of bleeding (≥Grade 3) was 2% on the Bortezomib for Injection arm and was <1% in the dexamethasone arm.

The incidence of bleeding events (≥Grade 3) was 1.7% in the VcR-CAP arm (four patients) and was 1.2% in the R-CHOP arm (three patients).

    Platelet transfusions were given to 23% of the patients in the VcR-CAP arm and 3% of the patients in the R-CHOP arm.

    The incidence of neutropenia (≥Grade 4) was 70% in the VcR-CAP arm and was 52% in the R-CHOP arm. The incidence of febrile neutropenia (≥Grade 4) was 5% in the VcR-CAP arm and was 6% in the R-CHOP arm. Myeloid growth factor support was provided at a rate of 78% in the VcR-CAP arm and 61% in the R-CHOP arm.

    5.8 Tumor Lysis Syndrome

    Tumor lysis syndrome has been reported with Bortezomib for Injection therapy. Patients at risk of tumor lysis syndrome are those with high tumor burden prior to treatment. Monitor patients closely and take appropriate precautions.

    5.9 Hepatic Toxicity

    Cases of acute liver failure have been reported in patients receiving multiple concomitant medications and with serious underlying medical conditions. Other reported hepatic reactions include hepatitis, increases in liver enzymes, and hyperbilirubinemia. Interrupt Bortezomib for Injection therapy to assess reversibility. There is limited rechallenge information in these patients.

    5.10 Thrombotic Microangiopathy

    Cases, sometimes fatal, of thrombotic microangiopathy, including thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS), have been reported in the postmarketing setting in patients who received Bortezomib for Injection. Monitor for signs and symptoms of TTP/HUS. If the diagnosis is suspected, stop Bortezomib for Injection and evaluate. If the diagnosis of TTP/HUS is excluded, consider restarting Bortezomib for Injection. The safety of reinitiating Bortezomib for Injection therapy in patients previously experiencing TTP/HUS is not known.

    5.11 Embryo-Fetal Toxicity

    Based on the mechanism of action and findings in animals, Bortezomib for Injection can cause fetal harm when administered to a pregnant woman. Bortezomib administered to rabbits during organogenesis at a dose approximately 0.5 times the clinical dose of 1.3 mg/m 2based on body surface area caused postimplantation loss and a decreased number of live fetuses [see Use in Specific Populations (8.1)] .

    Advise females of reproductive potential to use effective contraception during treatment with Bortezomib for Injection and for seven months following treatment. Advise males with female partners of reproductive potential to use effective contraception during treatment with Bortezomib for Injection and for four months following treatment. If Bortezomib for Injection is used during pregnancy or if the patient becomes pregnant during Bortezomib for Injection treatment, the patient should be apprised of the potential risk to the fetus [see Use in Specific Populations (8.1, 8.3), Nonclinical Toxicology (13.1)].

  • 6 ADVERSE REACTIONS

    The following clinically significant adverse reactions are also discussed in other sections of the labeling:

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

    Summary of Clinical Trial in Patients with Previously Untreated Multiple Myeloma

    describes safety data from 340 patients with previously untreated multiple myeloma who received Bortezomib for Injection (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 for Injection in combination with melphalan/prednisone is consistent with the known safety profiles of both Bortezomib for Injection and melphalan/prednisone.

    Relapsed Multiple Myeloma Randomized Study of Bortezomib for Injection vs Dexamethasone

    The safety data described below and in Table 10reflect exposure to either Bortezomib for Injection (n=331) or dexamethasone (n=332) in a study of patients with relapsed multiple myeloma. Bortezomib for Injection was administered intravenously at doses of 1.3 mg/m 2twice weekly for two out of three weeks (21 day cycle). After eight, 21 day cycles patients continued therapy for three, 35 day cycles on a weekly schedule. Duration of treatment was up to 11 cycles (nine months) with a median duration of six cycles (4.1 months). For inclusion in the trial, patients must have had measurable disease and one to three prior therapies. There was no upper age limit for entry. Creatinine clearance could be as low as 20 mL/min and bilirubin levels as high as 1.5 times the upper limit of normal. The overall frequency of adverse reactions was similar in men and women, and in patients <65 and ≥65 years of age. Most patients were Caucasian [see Clinical Studies (14.1) ].

    Among the 331 Bortezomib for Injection-treated patients, the most commonly reported (>20%) adverse reactions overall were nausea (52%), diarrhea (52%), fatigue (39%), peripheral neuropathies (35%), thrombocytopenia (33%), constipation (30%), vomiting (29%), and anorexia (21%). The most commonly reported (>20%) adverse reaction reported among the 332 patients in the dexamethasone group was fatigue (25%). Eight percent (8%) of patients in the Bortezomib for Injection-treated arm experienced a Grade 4 adverse reaction; the most common reactions were thrombocytopenia (4%) and neutropenia (2%). Nine percent (9%) of dexamethasone-treated patients experienced a Grade 4 adverse reaction. All individual dexamethasone-related Grade 4 adverse reactions were less than 1%.

    Serious Adverse Reactions and Adverse Reactions Leading to Treatment Discontinuation in the Relapsed Multiple Myeloma Study of Bortezomib for Injection vs Dexamethasone
    Serious adverse reactions are defined as any reaction that results in death, is life-threatening, requires hospitalization or prolongs a current hospitalization, results in a significant disability, or is deemed to be an important medical event. A total of 80 (24%) patients from the Bortezomib for Injection-treatment arm experienced a serious adverse reaction during the study, as did 83 (25%) dexamethasone‑treated patients. The most commonly reported serious adverse reactions in the Bortezomib for Injection-treatment arm were diarrhea (3%), dehydration, herpes zoster, pyrexia, nausea, vomiting, dyspnea, and thrombocytopenia (2% each). In the dexamethasone treatment group, the most commonly reported serious adverse reactions were pneumonia (4%), hyperglycemia (3%), pyrexia, and psychotic disorder (2% each).

    A total of 145 patients, including 84 (25%) of 331 patients in the Bortezomib for Injection treatment group and 61 (18%) of 332 patients in the dexamethasone treatment group were discontinued from treatment due to adverse reactions. Among the 331 Bortezomib for Injection-treated patients, the most commonly reported adverse reaction leading to discontinuation was peripheral neuropathy (8%). Among the 332 patients in the dexamethasone group, the most commonly reported adverse reactions leading to treatment discontinuation were psychotic disorder and hyperglycemia (2% each).

    Four deaths were considered to be Bortezomib for Injection-related in this relapsed multiple myeloma study: one case each of cardiogenic shock, respiratory insufficiency, congestive heart failure and cardiac arrest. Four deaths were considered dexamethasone-related: two cases of sepsis, one case of bacterial meningitis, and one case of sudden death at home.

    Most Commonly Reported Adverse Reactions in the Relapsed Multiple Myeloma Study of Bortezomib for Injection vs Dexamethasone
    The most common adverse reactions from the relapsed multiple myeloma study are shown in Table 10. All adverse reactions with incidence ≥10% in the Bortezomib for Injection arm are included.

    Safety Experience from the Phase 2 Open-Label Extension Study in Relapsed Multiple Myeloma
    In the Phase 2 extension study of 63 patients, no new cumulative or new long-term toxicities were observed with prolonged Bortezomib for Injection treatment. These patients were treated for a total of 5.3 to 23 months, including time on Bortezomib for Injection in the prior Bortezomib for Injection study [see Clinical Studies (14.1)] .

    Safety Experience from the Phase 3 Open-Label Study of Bortezomib for Injection Subcutaneous vs Intravenous in Relapsed Multiple Myeloma
    The safety and efficacy of Bortezomib for Injection administered subcutaneously were evaluated in one Phase 3 study at the recommended dose of 1.3 mg/m 2. This was a randomized, comparative study of Bortezomib for Injection subcutaneous vs intravenous in 222 patients with relapsed multiple myeloma. The safety data described below and in Table 11reflect exposure to either Bortezomib for Injection subcutaneous (N=147) or Bortezomib for Injection intravenous (N=74) [see Clinical Studies (14.1)] .

    Note: Safety population: 147 patients in the subcutaneous treatment group and 74 patients in the intravenous treatment group who received at least one dose of study medication

    In general, safety data were similar for the subcutaneous and intravenous treatment groups. Differences were observed in the rates of some Grade ≥3 adverse reactions. Differences of ≥5% were reported in neuralgia (3% subcutaneous vs 9% intravenous), peripheral neuropathies (6% subcutaneous vs 15% intravenous), neutropenia (13% subcutaneous vs 18% intravenous), and thrombocytopenia (8% subcutaneous vs 16% intravenous).

    A local reaction was reported in 6% of patients in the subcutaneous group, mostly redness. Only two (1%) patients were reported as having severe reactions, one case of pruritus and one case of redness. Local reactions led to reduction in injection concentration in one patient and drug discontinuation in one patient. Local reactions resolved in a median of six days.

    Dose reductions occurred due to adverse reactions in 31% of patients in the subcutaneous treatment group compared with 43% of the intravenously-treated patients. The most common adverse reactions leading to a dose reduction included peripheral sensory neuropathy (17% in the subcutaneous treatment group compared with 31% in the intravenous treatment group); and neuralgia (11% in the subcutaneous treatment group compared with 19% in the intravenous treatment group).

    Serious Adverse Reactions and Adverse Reactions Leading to Treatment Discontinuation in the Relapsed Multiple Myeloma Study of Bortezomib for Injection Subcutaneous vs Intravenous
    The incidence of serious adverse reactions was similar for the subcutaneous treatment group (20%) and the intravenous treatment group (19%). The most commonly reported serious adverse reactions in the subcutaneous treatment arm were pneumonia and pyrexia (2% each). In the intravenous treatment group, the most commonly reported serious adverse reactions were pneumonia, diarrhea, and peripheral sensory neuropathy (3% each).

    In the subcutaneous treatment group, 27 patients (18%) discontinued study treatment due to an adverse reaction compared with 17 patients (23%) in the intravenous treatment group .Among the 147 subcutaneously-treated patients, the most commonly reported adverse reactions leading to discontinuation were peripheral sensory neuropathy (5%) and neuralgia (5%). Among the 74 patients in the intravenous treatment group, the most commonly reported adverse reactions leading to treatment discontinuation were peripheral sensory neuropathy (9%) and neuralgia (9%).

    Two patients (1%) in the subcutaneous treatment group and one (1%) patient in the intravenous treatment group died due to an adverse reaction during treatment. In the subcutaneous group the causes of death were one case of pneumonia and one case of sudden death. In the intravenous group the cause of death was coronary artery insufficiency.

    Safety Experience from the Clinical Trial in Patients with Previously Untreated Mantle Cell Lymphoma
    Table 12describes safety data from 240 patients with previously untreated mantle cell lymphoma who received Bortezomib for Injection (1.3 mg/m 2) administered intravenously in combination with rituximab (375 mg/m 2), cyclophosphamide (750 mg/m 2), doxorubicin (50 mg/m 2), and prednisone (100 mg/m 2) (VcR-CAP) in a prospective randomized study.

    Infections were reported for 31% of patients in the VcR-CAP arm and 23% of the patients in the comparator (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone [R-CHOP]) arm, including the predominant preferred term of pneumonia (VcR-CAP 8% vs R-CHOP 5%).

    Key: R-CHOP = rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone; VcR-CAP = Bortezomib for Injection, rituximab, cyclophosphamide, doxorubicin, and prednisone.

    The incidence of herpes zoster reactivation was 4.6% in the VcR-CAP arm and 0.8% in the R-CHOP arm. Antiviral prophylaxis was mandated by protocol amendment.

    The incidences of Grade ≥3 bleeding events were similar between the two arms (four patients in the VcR-CAP arm and three patients in the R-CHOP arm). All of the Grade ≥3 bleeding events resolved without sequelae in the VcR-CAP arm.

    Adverse reactions leading to discontinuation occurred in 8% of patients in VcR-CAP group and 6% of patients in R-CHOP group. In the VcR-CAP group, the most commonly reported adverse reaction leading to discontinuation was peripheral sensory neuropathy (1%; three patients). The most commonly reported adverse reaction leading to discontinuation in the R-CHOP group was febrile neutropenia (<1%; two patients).

    Integrated Summary of Safety (Relapsed Multiple Myeloma and Relapsed Mantle Cell Lymphoma)
    Safety data from Phase 2 and 3 studies of single agent Bortezomib for Injection 1.3 mg/m 2/dose twice weekly for two weeks followed by a ten day rest period in 1163 patients with previously-treated multiple myeloma (N=1008) and previously-treated mantle cell lymphoma (N=155) were integrated and tabulated. This analysis does not include data from the Phase 3 open-label study of Bortezomib for Injection subcutaneous vs intravenous in relapsed multiple myeloma. In the integrated studies, the safety profile of Bortezomib for Injection was similar in patients with multiple myeloma and mantle cell lymphoma.

    In the integrated analysis, the most commonly reported (>20%) adverse reactions were nausea (49%), diarrhea (46%), asthenic conditions including fatigue (41%) and weakness (11%), peripheral neuropathies (38%), thrombocytopenia (32%), vomiting (28%), constipation (25%), and pyrexia (21%). Eleven percent (11%) of patients experienced at least one episode of ≥Grade 4 toxicity, most commonly thrombocytopenia (4%) and neutropenia (2%).

    In the Phase 2 relapsed multiple myeloma clinical trials of Bortezomib for Injection administered intravenously, local skin irritation was reported in 5% of patients, but extravasation Bortezomib for Injection was not associated with tissue damage.

    Serious Adverse Reactions and Adverse Reactions Leading to Treatment Discontinuation in the Integrated Summary of Safety
    A total of 26% of patients experienced a serious adverse reaction during the studies. The most commonly reported serious adverse reactions included diarrhea, vomiting and pyrexia (3% each), nausea, dehydration, and thrombocytopenia (2% each) and pneumonia, dyspnea, peripheral neuropathies, and herpes zoster (1% each).

    Adverse reactions leading to discontinuation occurred in 22% of patients. The reasons for discontinuation included peripheral neuropathy (8%), and fatigue, thrombocytopenia, and diarrhea (2% each).

    In total, 2% of the patients died and the cause of death was considered by the investigator to be possibly related to study drug: including reports of cardiac arrest, congestive heart failure, respiratory failure, renal failure, pneumonia and sepsis.

    Most Commonly Reported Adverse Reactions in the Integrated Summary of Safety
    The most common adverse reactions are shown in Table 13. All adverse reactions occurring at ≥10% are included. In the absence of a randomized comparator arm, it is often not possible to distinguish between adverse events that are drug-caused and those that reflect the patient’s underlying disease. Please see the discussion of specific adverse reactions that follows.

    Description of Selected Adverse Reactions from the Integrated Phase 2 and 3 Relapsed Multiple Myeloma and Phase 2 Relapsed Mantle Cell Lymphoma Studies
    Gastrointestinal Toxicity
    A total of 75% of patients experienced at least one gastrointestinal disorder. The most common gastrointestinal disorders included nausea, diarrhea, constipation, vomiting, and appetite decreased. Other gastrointestinal disorders included dyspepsia and dysgeusia. Grade 3 adverse reactions occurred in 14% of patients; ≥Grade 4 adverse reactions were ≤1%. Gastrointestinal adverse reactions were considered serious in 7% of patients. Four percent (4%) of patients discontinued due to a gastrointestinal adverse reaction. Nausea was reported more often in patients with multiple myeloma (51%) compared to patients with mantle cell lymphoma (36%).

    Thrombocytopenia
    Across the studies, Bortezomib for Injection-associated thrombocytopenia was characterized by a decrease in platelet count during the dosing period (Days 1 to 11) and a return toward baseline during the ten day rest period during each treatment cycle. Overall, thrombocytopenia was reported in 32% of patients. Thrombocytopenia was Grade 3 in 22%, ≥Grade 4 in 4%, and serious in 2% of patients, and the reaction resulted in Bortezomib for Injection discontinuation in 2% of patients [see Warnings and Precautions (5.7)] . Thrombocytopenia was reported more often in patients with multiple myeloma (34%) compared to patients with mantle cell lymphoma (16%). The incidence of  ≥Grade 3 thrombocytopenia also was higher in patients with multiple myeloma (28%) compared to patients with mantle cell lymphoma (8%).

    Peripheral Neuropathy
    Overall, peripheral neuropathies occurred in 38% of patients. Peripheral neuropathy was Grade 3 for 11% of patients and ≥Grade 4 for <1% of patients. Eight percent (8%) of patients discontinued Bortezomib for Injection due to peripheral neuropathy. The incidence of peripheral neuropathy was higher among patients with mantle cell lymphoma (54%) compared to patients with multiple myeloma (36%).

    In the Bortezomib for Injection vs dexamethasone Phase 3 relapsed multiple myeloma study, among the 62 Bortezomib for Injection-treated patients who experienced ≥Grade 2 peripheral neuropathy and had dose adjustments, 48% had improved or resolved with a median of 3.8 months from first onset.

    In the Phase 2 relapsed multiple myeloma studies, among the 30 patients who experienced Grade 2 peripheral neuropathy resulting in discontinuation or who experienced ≥Grade 3 peripheral neuropathy, 73% reported improvement or resolution with a median time of 47 days to improvement of one grade or more from the last dose of Bortezomib for Injection.

    Hypotension
    The incidence of hypotension (postural, orthostatic and hypotension NOS) was 8% in patients treated with Bortezomib for Injection. Hypotension was Grade 1 or 2 in the majority of patients and Grade 3 in 2% and ≥Grade 4 in <1%. Two percent (2%) of patients had hypotension reported as a serious adverse reaction, and 1% discontinued due to hypotension. The incidence of hypotension was similar in patients with multiple myeloma (8%) and those with mantle cell lymphoma (9%). In addition, <1% of patients experienced hypotension associated with a syncopal reaction.

    Neutropenia
    Neutrophil counts decreased during the Bortezomib for Injection dosing period (Days 1 to 11) and returned toward baseline during the ten day rest period during each treatment cycle. Overall, neutropenia occurred in 15% of patients and was Grade 3 in 8% of patients and ≥Grade 4 in 2%. Neutropenia was reported as a serious adverse reaction in <1% of patients and <1% of patients discontinued due to neutropenia. The incidence of neutropenia was higher in patients with multiple myeloma (16%) compared to patients with mantle cell lymphoma (5%). The incidence of ≥Grade 3 neutropenia also was higher in patients with multiple myeloma (12%) compared to patients with mantle cell lymphoma (3%).

    Asthenic Conditions (Fatigue, Malaise, Weakness, Asthenia)
    Asthenic conditions were reported in 54% of patients. Fatigue was reported as Grade 3 in 7% and ≥Grade 4 in <1% of patients. Asthenia was reported as Grade 3 in 2% and ≥Grade 4 in <1% of patients. Two percent (2%) of patients discontinued treatment due to fatigue and <1% due to weakness and asthenia. Asthenic conditions were reported in 53% of patients with multiple myeloma and 59% of patients with mantle cell lymphoma.

    Pyrexia
    Pyrexia (>38ºC) was reported as an adverse reaction for 21% of patients. The reaction was Grade 3 in 1% and ≥Grade 4 in <1%. Pyrexia was reported as a serious adverse reaction in 3% of patients and led to Bortezomib for Injection discontinuation in <1% of patients. The incidence of pyrexia was higher among patients with multiple myeloma (23%) compared to patients with mantle cell lymphoma (10%). The incidence of ≥Grade 3 pyrexia was 1% in patients with multiple myeloma and <1% in patients with mantle cell lymphoma.

    Herpes Virus Infection
    Consider using antiviral prophylaxis in subjects being treated with Bortezomib for Injection. In the randomized studies in previously untreated and relapsed multiple myeloma, herpes zoster reactivation was more common in subjects treated with Bortezomib for Injection (ranging between 6 to 11%) than in the control groups (3 to 4%). Herpes simplex was seen in 1 to 3% in subjects treated with Bortezomib for Injection and 1 to 3% in the control groups. In the previously untreated multiple myeloma study, herpes zoster virus reactivation in the Bortezomib for Injection, melphalan and prednisone arm was less common in subjects receiving prophylactic antiviral therapy (3%) than in subjects who did not receive prophylactic antiviral therapy (17%).

    Retreatment in Relapsed Multiple Myeloma
    A single-arm trial was conducted in 130 patients with relapsed multiple myeloma to determine the efficacy and safety of retreatment with intravenous Bortezomib for Injection. The safety profile of patients in this trial is consistent with the known safety profile of Bortezomib for Injection-treated patients with relapsed multiple myeloma as demonstrated in Tables 10, 11, and 13; no cumulative toxicities were observed upon retreatment. The most common adverse drug reaction was thrombocytopenia which occurred in 52% of the patients. The incidence of ≥Grade 3 thrombocytopenia was 24%. Peripheral neuropathy occurred in 28% of patients, with the incidence of ≥Grade 3 peripheral neuropathy reported at 6%.

    The incidence of serious adverse reactions was 12.3%. The most commonly reported serious adverse reactions were thrombocytopenia (3.8%), diarrhea (2.3%), and herpes zoster and pneumonia (1.5% each).

    Adverse reactions leading to discontinuation occurred in 13% of patients. The reasons for discontinuation included peripheral neuropathy (5%) and diarrhea (3%).

    Two deaths considered to be Bortezomib for Injection-related occurred within 30 days of the last Bortezomib for Injection dose; one in a patient with cerebrovascular accident and one in a patient with sepsis.

  • 7 DRUG INTERACTIONS

    7.1 Effects of Other Drugs on Bortezomib for Injection

    Strong CYP3A4 Inducers
    Coadministration with a strong CYP3A4 inducer decreases the exposure of bortezomib [see Clinical Pharmacology (12.3)] which may decrease Bortezomib for Injection efficacy. Avoid coadministration with strong CYP3A4 inducers.

    Strong CYP3A4 Inhibitors
    Coadministration with a strong CYP3A4 inhibitor increases the exposure of bortezomib [see Clinical Pharmacology (12.3)] which may increase the risk of Bortezomib for Injection toxicities. Monitor patients for signs of bortezomib toxicity and consider a bortezomib dose reduction if bortezomib must be given in combination with strong CYP3A4 inhibitors.

    7.2 Drugs Without Clinically Significant Interactions with Bortezomib for Injection

    No clinically significant drug interactions have been observed when Bortezomib for Injection was coadministered with dexamethasone, omeprazole, or melphalan in combination with prednisone [see Clinical Pharmacology (12.3)] .

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary
    Based on its mechanism of action [see Clinical Pharmacology (12.1)] and findings in animals, Bortezomib for Injection can cause fetal harm when administered to a pregnant woman. There are no studies with the use of Bortezomib for Injection 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 2in the rat and 0.05 mg/kg; 0.6 mg/m 2in the rabbit) when administered during organogenesis. These dosages are approximately 0.5 times the clinical dose of 1.3 mg/m 2based 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 2based 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 postimplantation loss and decreased number of live fetuses. Live fetuses from these litters also showed significant decreases in fetal weight.

    8.2 Lactation

    Risk Summary

    There are no data on the presence of bortezomib or its metabolites in human milk, the effects of the drug on the breastfed child, or the effects of the drug on milk production. Because many drugs are excreted in human milk and because the potential for serious adverse reactions in a breastfed child from Bortezomib for Injection is unknown, advise nursing women not to breastfeed during treatment with Bortezomib for Injection and for two months after treatment.

    8.3 Females and Males of Reproductive Potential

    Based on its mechanism of action and findings in animals, Bortezomib for Injection can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].

    Pregnancy Testing
    Conduct pregnancy testing in females of reproductive potential prior to initiating Bortezomib for Injection treatment.

    Contraception
    Females
    Advise females of reproductive potential to use effective contraception during treatment with Bortezomib for Injection and for seven months after the last dose.

    Males
    Males with female partners of reproductive potential should use effective contraception during treatment with Bortezomib for Injection and for four months after the last dose.

    Infertility
    Based on the mechanism of action and findings in animals, Bortezomib for Injection may have an effect on either male or female fertility [see Nonclinical Toxicology (13.1)] .

    8.4 Pediatric Use

    Safety and effectiveness have not been established in pediatric patients.

    The activity and safety of Bortezomib for Injection in combination with intensive reinduction chemotherapy was evaluated in pediatric and young adult patients with lymphoid malignancies (pre-B cell ALL 77%, 16% with T-cell ALL, and 7% T-cell lymphoblastic lymphoma (LL)), all of whom relapsed within 36 months of initial diagnosis in a single-arm multicenter, nonrandomized cooperative group trial. An effective reinduction multiagent chemotherapy regimen was administered in three blocks. Block 1 included vincristine, prednisone, doxorubicin and pegaspargase; Block 2 included cyclophosphamide, etoposide and methotrexate; Block 3 included high-dose cytosine arabinoside and asparaginase.Bortezomib for Injection was administered at a dose of 1.3 mg/m 2as a bolus intravenous injection on Days 1, 4, 8, and 11 of Block 1 and Days 1, 4, and 8 of Block 2. There were 140 patients with ALL or LL enrolled and evaluated for safety. The median age was ten years (range: 1 to 26), 57% were male, 70% were white, 14% were black, 4% were Asian, 2% were American Indian/Alaska Native, 1% were Pacific Islander.

    The activity was evaluated in a prespecified subset of the first 60 evaluable patients enrolled on the study with pre-B ALL ≤21 years and relapsed <36 months from diagnosis. The complete remission (CR) rate at day 36 was compared to that in a historical control set of patients who had received the identical backbone therapy without Bortezomib for Injection. There was no evidence that the addition of Bortezomib for Injection had any impact on the CR rate.

    No new safety concerns were observed when Bortezomib for Injection was added to a chemotherapy backbone regimen as compared with a historical control group in which the backbone regimen was given without Bortezomib for Injection.

    The BSA-normalized clearance of bortezomib in pediatric patients was similar to that observed in adults.

    8.5 Geriatric Use

    Of the 669 patients enrolled in the relapsed multiple myeloma study, 245 (37%) were 65 years of age or older: 125 (38%) on the Bortezomib for Injection arm and 120 (36%) on the dexamethasone arm. Median time to progression and median duration of response for patients ≥65 were longer on Bortezomib for Injection compared to dexamethasone [5.5 mo vs 4.3 mo, and 8.0 mo vs 4.9 mo, respectively]. On the Bortezomib for Injection arm, 40% (n=46) of evaluable patients aged ≥65 experienced response (CR + PR) vs 18% (n=21) on the dexamethasone arm. The incidence of Grade 3 and 4 events was 64%, 78% and 75% for Bortezomib for Injection patients ≤50, 51 to 64 and ≥65 years old, respectively [see Adverse Reactions (6.1), Clinical Studies (14.1)] .

    No overall differences in safety or effectiveness were observed between patients ≥age 65 and younger patients receiving Bortezomib for Injection; but greater sensitivity of some older individuals cannot be ruled out.

    8.6 Renal Impairment

    No starting dosage adjustment of Bortezomib for Injection is recommended for patients with renal impairment. In patients requiring dialysis, Bortezomib for Injection should be administered after the dialysis procedure [see Clinical Pharmacology (12.3)] .

    8.7 Hepatic Impairment

    No starting dosage adjustment of Bortezomib for Injection is recommended for patients with mild hepatic impairment (total bilirubin ≤1x ULN and AST >ULN, or total bilirubin >1 to 1.5x ULN and any AST). The exposure of bortezomib is increased in patients with moderate (total bilirubin ≥1.5 to 3x ULN and any AST) and severe (total bilirubin >3x ULN and any AST) hepatic impairment. Reduce the starting dose in patients with moderate or severe hepatic impairment [see Dosage and Administration (2.8), Clinical Pharmacology (12.3)] .

    8.8 Patients with Diabetes

    During clinical trials, hypoglycemia and hyperglycemia were reported in diabetic patients receiving oral hypoglycemics. Patients on oral antidiabetic agents receiving Bortezomib for Injection treatment may require close monitoring of their blood glucose levels and adjustment of the dose of their antidiabetic medication.

  • 10 OVERDOSAGE

    There is no known specific antidote for Bortezomib for Injection overdosage. In humans, fatal outcomes following the administration of more than twice the recommended therapeutic dose have been reported, which were associated with the acute onset of symptomatic hypotension ( 5.2) and thrombocytopenia ( 5.7). In the event of an overdosage, the patient’s vital signs should be monitored and appropriate supportive care given.

    Studies in monkeys and dogs showed that intravenous bortezomib doses as low as two times the recommended clinical dose on a mg/m 2basis were associated with increases in heart rate, decreases in contractility, hypotension, and death. In dog studies, a slight increase in the corrected QT interval was observed at doses resulting in death. In monkeys, doses of 3.0 mg/m 2and greater (approximately twice the recommended clinical dose) resulted in hypotension starting at one hour postadministration, with progression to death in 12 to 14 hours following drug administration.

  • 11 DESCRIPTION

    Bortezomib for Injection, a proteasome inhibitor, contains bortezomib which is an antineoplastic agent. Bortezomib is a modified dipeptidyl boronic acid. The chemical name for bortezomib, the monomeric boronic acid, is [(1R)-3-methyl-1-[[(2S)-1-oxo-3-phenyl-2-[(pyrazinylcarbonyl) amino]propyl]amino]butyl] boronic acid.

    Bortezomib has the following chemical structure:

    Bortezomib Chemical Structure

    The molecular weight is 384.24. The molecular formula is C 19H 25BN 4O 4. The solubility of bortezomib, as the monomeric boronic acid, in water is 3.3 to 3.8 mg/mL in a pH range of 2 to 6.5.

    Bortezomib for Injection is available for intravenous injection or subcutaneous use. Each single-dose vial contains 3.5 mg of bortezomib as a sterile lyophilized powder. It also contains the inactive ingredient: 35 mg mannitol, USP. The product is provided as a mannitol boronic ester which, in reconstituted form, consists of the mannitol ester in equilibrium with its hydrolysis product, the monomeric boronic acid. The drug substance exists in its cyclic anhydride form as a trimeric boroxine.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Bortezomib is a reversible inhibitor of the chymotrypsin-like activity of the 26S proteasome in mammalian cells. The 26S proteasome is a large protein complex that degrades ubiquitinated proteins. The ubiquitin-proteasome pathway plays an essential role in regulating the intracellular concentration of specific proteins, thereby maintaining homeostasis within cells. Inhibition of the 26S proteasome prevents this targeted proteolysis, which can affect multiple signaling cascades within the cell. This disruption of normal homeostatic mechanisms can lead to cell death. Experiments have demonstrated that bortezomib is cytotoxic to a variety of cancer cell types in vitro. Bortezomib causes a delay in tumor growth in vivoin nonclinical tumor models, including multiple myeloma.

    12.2 Pharmacodynamics

    Following twice weekly administration of 1 mg/m 2and 1.3 mg/m 2bortezomib doses, the maximum inhibition of 20S proteasome activity (relative to baseline) in whole blood was observed five minutes after drug administration. Comparable maximum inhibition of 20S proteasome activity was observed between 1 and 1.3 mg/m 2doses. Maximal inhibition ranged from 70% to 84% and from 73% to 83% for the 1 mg/m 2and 1.3 mg/m 2dose regimens, respectively.

    12.3 Pharmacokinetics

    Following intravenous administration of 1 mg/m 2and 1.3 mg/m 2doses, the mean maximum plasma concentrations of bortezomib (C max) after the first dose (Day 1) were 57 and 112 ng/mL, respectively. When administered twice weekly, the mean maximum observed plasma concentrations ranged from 67 to 106 ng/mL for the 1 mg/m 2dose and 89 to 120 ng/mL for the 1.3 mg/m 2dose.

    Following an intravenous bolus or subcutaneous injection of a 1.3 mg/m 2dose to patients with multiple myeloma, the total systemic exposure after repeat dose administration (AUC last) was equivalent for subcutaneous and intravenous administration. The AUC lastgeometric mean ratio (90% confidence interval) was 0.99 (0.80 to 1.23). The C maxafter subcutaneous administration (20.4 ng/mL) was lower than after intravenous administration (223 ng/mL) with repeat dose administration.

    Distribution
    The mean distribution volume of bortezomib ranged from approximately 498 to 1884 L/m 2following single- or repeat-dose administration of 1 mg/m 2or 1.3 mg/m 2to patients with multiple myeloma. The binding of bortezomib to human plasma proteins averaged 83% over the concentration range of 100 to 1000 ng/mL.

    Elimination
    The mean elimination half-life of bortezomib upon multiple dosing ranged from 40 to 193 hours after the 1 mg/m 2dose and 76 to 108 hours after the 1.3 mg/m 2dose. The mean total body clearances were 102 and 112 L/h following the first dose for doses of 1 mg/m 2and 1.3 mg/m 2, respectively, and ranged from 15 to 32 L/h following subsequent doses for doses of 1 and 1.3 mg/m 2, respectively.

    Metabolism
    Bortezomib is primarily oxidatively metabolized to several inactive metabolites in vitro via cytochrome P450 (CYP) enzymes 3A4, CYP2C19, and CYP1A2, and to a lesser extent by CYP2D6 and CYP2C9.

    Excretion
    The pathways of elimination of bortezomib have not been characterized in humans.

    Specific Populations
    No clinically significant differences in the pharmacokinetics of bortezomib were observed based on age, sex, or renal impairment (including patients administered Bortezomib for Injection after dialysis). The effect of race on bortezomib pharmacokinetics is unknown.

    Patients with Hepatic Impairment
    Following administration of bortezomib doses ranging from 0.5 to 1.3 mg/m 2, mild (total bilirubin ≤1x ULN and AST >ULN, or total bilirubin >1 to 1.5x ULN and any AST) hepatic impairment did not alter dose-normalized bortezomib AUC when compared to patients with normal hepatic function. Dose normalized mean bortezomib AUC increased by approximately 60% in patients with moderate (total bilirubin >1.5 to 3x ULN and any AST) or severe (total bilirubin >3x ULN and any AST) hepatic impairment. A lower starting dose is recommended in patients with moderate or severe hepatic impairment.

    Drug Interaction Studies
    Clinical Studies
    No clinically significant differences in bortezomib pharmacokinetics were observed when coadministered with dexamethasone (weak CYP3A4 inducer), omeprazole (strong CYP2C19 inhibitor), or melphalan in combination with prednisone.

    Strong CYP3A4 Inhibitor
    Coadministration with ketoconazole (strong CYP3A4 inhibitor) increased bortezomib exposure by 35%.

    Strong CYP3A4 Inducer
    Coadministration with rifampin (strong CYP3A4 inducer) decreased bortezomib exposure by approximately 45%.

    In Vitro Studies
    Bortezomib may inhibit CYP2C19 activity and increase exposure to drugs that are substrates for this enzyme.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenicity studies have not been conducted with bortezomib.

    Bortezomib showed clastogenic activity (structural chromosomal aberrations) in the in vitrochromosomal aberration assay using Chinese hamster ovary cells. Bortezomib was not genotoxic when tested in the in vitromutagenicity assay (Ames test) and in vivomicronucleus assay in mice.

    Fertility studies with bortezomib were not performed but evaluation of reproductive tissues has been performed in the general toxicity studies. In the six month rat toxicity study, degenerative effects in the ovary were observed at doses ≥0.3  mg/m 2(one-fourth of the recommended clinical dose), and degenerative changes in the testes occurred at 1.2  mg/m 2.

    13.2 Animal Toxicology and/or Pharmacology

    Cardiovascular Toxicity

    Studies in monkeys showed that administration of dosages approximately twice the recommended clinical dose resulted in heart rate elevations, followed by profound progressive hypotension, bradycardia, and death 12 to 14 hours postdose. Doses ≥1.2 mg/m 2induced dose-proportional changes in cardiac parameters. Bortezomib has been shown to distribute to most tissues in the body, including the myocardium. In a repeated dosing toxicity study in the monkey, myocardial hemorrhage, inflammation, and necrosis were also observed.

    Chronic Administration

    In animal studies at a dose and schedule similar to that recommended for patients (twice weekly dosing for two weeks followed by one week rest), toxicities observed included severe anemia and thrombocytopenia, and gastrointestinal, neurological and lymphoid system toxicities. Neurotoxic effects of bortezomib in animal studies included axonal swelling and degeneration in peripheral nerves, dorsal spinal roots, and tracts of the spinal cord. Additionally, multifocal hemorrhage and necrosis in the brain, eye, and heart were observed.

  • 14 CLINICAL STUDIES

    14.1 Multiple Myeloma

    Randomized, Open-Label Clinical Study in Patients with Previously Untreated Multiple Myeloma
    A prospective, international, randomized (1:1), open-label clinical study (NCT00111319) of 682 patients was conducted to determine whether Bortezomib for Injection administered intravenously (1.3 mg/m 2) in combination with melphalan (9 mg/m 2) and prednisone (60 mg/m 2) resulted in improvement in time to progression (TTP) when compared to melphalan (9 mg/m 2) and prednisone (60 mg/m 2) in patients with previously untreated multiple myeloma. Treatment was administered for a maximum of nine cycles (approximately 54 weeks) and was discontinued early for disease progression or unacceptable toxicity. Antiviral prophylaxis was recommended for patients on the Bortezomib for Injection study arm.

    The median age of the patients in the study was 71 years (48;91), 50% were male, 88% were Caucasian and the median Karnofsky performance status score for the patients was 80 (60;100). Patients had IgG/IgA/Light chain myeloma in 63%/25%/8% instances, a median hemoglobin of 105 g/L (64;165), and a median platelet count of 221,500/microliter (33,000;587,000).

    Efficacy results for the trial are presented in Table 14. At a prespecified interim analysis (with median follow-up of 16.3 months), the combination of Bortezomib for Injection, melphalan and prednisone therapy resulted in significantly superior results for time to progression, progression-free survival, overall survival and response rate. Further enrollment was halted, and patients receiving melphalan and prednisone were offered Bortezomib for Injection in addition. A later, prespecified analysis of overall survival (with median follow-up of 36.7 months with a hazard ratio of 0.65, 95% CI: 0.51, 0.84) resulted in a statistically significant survival benefit for the Bortezomib for Injection, melphalan and prednisone treatment arm despite subsequent therapies including Bortezomib for Injection based regimens. In an updated analysis of overall survival based on 387 deaths (median follow-up 60.1 months), the median overall survival for the Bortezomib for Injection, melphalan and prednisone treatment arm was 56.4 months and for the melphalan and prednisone treatment arm was 43.1 months, with a hazard ratio of 0.695 (95% CI: 0.57, 0.85).

    Randomized, Clinical Study in Relapsed Multiple Myeloma of Bortezomib for Injection vs Dexamethasone

    A prospective Phase 3, international, randomized (1:1), stratified, open-label clinical study (NCT00048230) enrolling 669 patients was designed to determine whether Bortezomib for Injection resulted in improvement in time to progression (TTP) compared to high-dose dexamethasone in patients with progressive multiple myeloma following 1 to 3 prior therapies. Patients considered to be refractory to prior high-dose dexamethasone were excluded as were those with baseline Grade ≥2 peripheral neuropathy or platelet counts <50,000/µL. A total of 627 patients were evaluable for response.

    Stratification factors were based on the number of lines of prior therapy the patient had previously received (one previous line vs more than one line of therapy), time of progression relative to prior treatment (progression during or within six months of stopping their most recent therapy vs relapse >6 months after receiving their most recent therapy), and screening beta 2-microglobulin levels (≤2.5 mg/L vs >2.5 mg/L).

Within each three week treatment cycle, Bortezomib for Injection 1.3 mg/m 2/dose alone was administered by intravenous bolus twice weekly for two weeks on Days 1, 4, 8, and 11 followed by a ten day rest period (Days 12 to 21). Within each five week treatment cycle, Bortezomib for Injection 1.3 mg/m 2/dose alone was administered by intravenous bolus once weekly for four weeks on Days 1, 8, 15, and 22 followed by a 13 day rest period (Days 23 to 35) [see Dosage and Administration (2.2)] .

    Patients in the dexamethasone treatment group were to receive 4, five week treatment cycles followed by 5, four week treatment cycles. Within each five week treatment cycle, dexamethasone 40 mg/day PO was administered once daily on Days 1 to 4, 9 to 12, and 17 to 20 followed by a 15 day rest period (Days 21 to 35). Within each four week treatment cycle, dexamethasone 40 mg/day PO was administered once daily on Days 1 to 4 followed by a 24 day rest period (Days 5 to 28). Patients with documented progressive disease on dexamethasone were offered Bortezomib for Injection at a standard dose and schedule on a companion study. Following a preplanned interim analysis of time to progression, the dexamethasone arm was halted and all patients randomized to dexamethasone were offered Bortezomib for Injection, regardless of disease status.

    In the Bortezomib for Injection arm, 34% of patients received at least one Bortezomib for Injection dose in all eight of the three week cycles of therapy, and 13% received at least one dose in all 11 cycles. The average number of Bortezomib for Injection doses during the study was 22, with a range of 1 to 44. In the dexamethasone arm, 40% of patients received at least one dose in all four of the five week treatment cycles of therapy, and 6% received at least one dose in all nine cycles.

    The time to event analyses and response rates from the relapsed multiple myeloma study are presented in Table 16. Response and progression were assessed using the European Group for Blood and Marrow Transplantation (EBMT) criteria. Complete response (CR) required <5% plasma cells in the marrow, 100% reduction in M-protein, and a negative immunofixation test (IF -). Partial response (PR) requires ≥50% reduction in serum myeloma protein and ≥90% reduction of urine myeloma protein on at least two occasions for a minimum of at least six weeks along with stable bone disease and normal calcium. Near complete response (nCR) was defined as meeting all the criteria for complete response including 100% reduction in M-protein by protein electrophoresis; however, M- protein was still detectable by immunofixation (IF +).

    TTP was statistically significantly longer on the Bortezomib for Injection arm (see ).

    Figure 3: Time to Progression Bortezomib vs Dexamethasone (Relapsed Multiple Myeloma Study)

    As shown in Bortezomib for Injection had a significant survival advantage relative to dexamethasone (p <0.05). The median follow-up was 8.3 months.

    Figure 4: Overall Survival Bortezomib vs Dexamethasone (Relapsed Multiple Myeloma Study)

    For the 121 patients achieving a response (CR or PR) on the Bortezomib for Injection arm, the median duration was 8.0 months (95% CI: 6.9, 11.5 months) compared to 5.6 months (95% CI: 4.8, 9.2 months) for the 56 responders on the dexamethasone arm. The response rate was significantly higher on the Bortezomib for Injection arm regardless of beta 2-microglobulin levels at baseline.

    Randomized, Open-Label Clinical Study of Bortezomib for Injection Subcutaneous vs Intravenous in Relapsed Multiple Myeloma
    An open-label, randomized, Phase 3 noninferiority study (NCT00722566) compared the efficacy and safety of the subcutaneous administration of Bortezomib for Injection vs the intravenous administration. This study included 222 bortezomib naïve patients with relapsed multiple myeloma, who were randomized in a 2:1 ratio to receive 1.3 mg/m 2of Bortezomib for Injection by either the subcutaneous (n=148) or intravenous (n=74) route for eight cycles. Patients who did not obtain an optimal response (less than Complete Response (CR)) to therapy with Bortezomib for Injection alone after four cycles were allowed to receive oral dexamethasone 20 mg daily on the day of and after Bortezomib for Injection administration (82 patients in subcutaneous treatment group and 39 patients in the intravenous treatment group). Patients with baseline Grade ≥2 peripheral neuropathy or neuropathic pain, or platelet counts <50,000/µL were excluded. A total of 218 patients were evaluable for response.

    Stratification factors were based on the number of lines of prior therapy the patient had received (one previous line vs more than one line of therapy), and international staging system (ISS) stage (incorporating beta 2-microglobulin and albumin levels; Stages I, II, or III).

    The baseline demographic and other characteristics of the two treatment groups are summarized as follows: the median age of the patient population was approximately 64 years of age (range: 38 to 88 years), primarily male (subcutaneous: 50%, intravenous: 64%); the primary type of myeloma is IgG (subcutaneous: 65% IgG, 26% IgA, 8% light chain; intravenous: 72% IgG, 19% IgA, 8% light chain), ISS staging I/II/III (%) was 27, 41, 32 for both subcutaneous and intravenous, Karnofsky performance status score was ≤70% in 22% of subcutaneous and 16% of intravenous, creatinine clearance was 67.5 mL/min in subcutaneous and 73 mL/min in intravenous, the median years from diagnosis was 2.68 and 2.93 in subcutaneous and intravenous respectively and the proportion of patients with more than one prior line of therapy was 38% in subcutaneous and 35% in intravenous.

    This study met its primary (noninferiority) objective that single agent subcutaneous Bortezomib for Injection retains at least 60% of the overall response rate after four cycles relative to single agent intravenous Bortezomib for Injection. The results are provided in Table 17.

    A Randomized, Phase 2 Dose-Response Study in Relapsed Multiple Myeloma
    An open-label, multicenter study randomized 54 patients with multiple myeloma who had progressed or relapsed on or after front-line therapy to receive Bortezomib for Injection 1 mg/m 2or 1.3 mg/m 2intravenous bolus twice weekly for two weeks on Days 1, 4, 8, and 11 followed by a ten day rest period (Days 12 to 21). The median duration of time between diagnosis of multiple myeloma and first dose of Bortezomib for Injection on this trial was two years, and patients had received a median of one prior line of treatment (median of three prior therapies). A single complete response was seen at each dose. The overall response rates (CR + PR) were 30% (8/27) at 1 mg/m 2and 38% (10/26) at 1.3 mg/m 2.

    A Phase 2 Open-Label Extension Study in Relapsed Multiple Myeloma
    Patients from the two Phase 2 studies, who in the investigators’ opinion would experience additional clinical benefit, continued to receive Bortezomib for Injection beyond 8 cycles on an extension study. Sixty-three (63) patients from the Phase 2 multiple myeloma studies were enrolled and received a median of seven additional cycles of Bortezomib for Injection therapy for a total median of 14 cycles (range: 7 to 32). The overall median dosing intensity was the same in both the parent protocol and extension study. Sixty-seven percent (67%) of patients initiated the extension study at the same or higher dose intensity at which they completed the parent protocol, and 89% of patients maintained the standard three week dosing schedule during the extension study. No new cumulative or new long-term toxicities were observed with prolonged Bortezomib for Injection treatment [see Adverse Reactions (6.1)] .

    A Single-Arm Trial of Retreatment in Relapsed Multiple Myeloma
    A single-arm, open-label trial (NCT00431769) was conducted to determine the efficacy and safety of retreatment with Bortezomib for Injection. One hundred and thirty patients (≥18 years of age) with multiple myeloma who previously had at least partial response on a Bortezomib for Injection-containing regimen (median of two prior lines of therapy [range: 1 to 7]) were retreated upon progression with Bortezomib for Injection administered intravenously. Patients were excluded from trial participation if they had peripheral neuropathy or neuropathic pain of Grade ≥2. At least six months after prior Bortezomib for Injection therapy, Bortezomib for Injection was restarted at the last tolerated dose of 1.3 mg/m 2(n=93) or ≤1 mg/m 2(n=37) and given on Days 1, 4, 8 and 11 every three weeks for maximum of eight cycles either as single agent or in combination with dexamethasone in accordance with the standard of care. Dexamethasone was administered in combination with Bortezomib for Injection to 83 patients in Cycle 1 with an additional 11 patients receiving dexamethasone during the course of Bortezomib for Injection retreatment cycles.

    The primary endpoint was best confirmed response to retreatment as assessed by European Group for Blood and Marrow Transplantation (EBMT) criteria. Fifty of the 130 patients achieved a best confirmed response of Partial Response or better for an overall response rate of 38.5% (95% CI: 30.1, 47.4). One patient achieved a Complete Response and 49 achieved Partial Response. In the 50 responding patients, the median duration of response was 6.5 months and the range was 0.6 to 19.3 months.

    14.2 Mantle Cell Lymphoma

    A Randomized, Open-Label Clinical Study in Patients with Previously Untreated Mantle Cell Lymphoma

    A randomized, open-label, Phase 3 study (NCT00722137) was conducted in 487 adult patients with previously untreated mantle cell lymphoma (Stage II, III or IV) who were ineligible or not considered for bone marrow transplantation to determine whether Bortezomib for Injection administered in combination with rituximab, cyclophosphamide, doxorubicin, and prednisone (VcR-CAP) resulted in improvement in progression-free survival (PFS) when compared to the combination of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). This clinical study utilized independent pathology confirmation and independent radiologic response assessment.

    Patients in the VcR-CAP treatment arm received Bortezomib for Injection (1.3 mg/m 2) administered intravenously on Days 1, 4, 8, and 11 (rest period Days 12 to 21); rituximab (375 mg/m 2) on Day 1; cyclophosphamide (750 mg/m 2) on Day 1; doxorubicin (50 mg/m 2) on Day 1; and prednisone (100 mg/m 2) on Day 1 through Day 5 of the 21 day treatment cycle. For patients with a response first documented at Cycle 6, two additional treatment cycles were allowed.

    Median patient age was 66 years, 74% were male, 66% were Caucasian and 32% were Asian. Sixty-nine percent of patients had a positive bone marrow aspirate and/or a positive bone marrow biopsy for MCL, 54% of patients had an International Prognostic Index (IPI) score of three (high‑intermediate) or higher and 76% had Stage IV disease.

    The majority of the patients in both groups received six or more cycles of treatment, 84% in the VcR-CAP group and 83% in the R-CHOP group. Median number of cycles received by patients in both treatment arms was six with 17% of patients in the R-CHOP group and 14% of subjects in the VcR-CAP group receiving up to two additional cycles.

    The efficacy results for PFS, CR and ORR with a median follow-up of 40 months are presented in Table 18. The response criteria used to assess efficacy were based on the International Workshop to Standardize Response Criteria for Non-Hodgkin’s Lymphoma (IWRC). Final overall survival results at a median follow-up of 78.5 months are also presented in Table 18and Figure 6. The combination of VcR-CAP resulted in statistically significant prolongation of PFS compared with R-CHOP ( see Table 18, ).

    A Phase 2 Single-Arm Clinical Study in Relapsed Mantle Cell Lymphoma after Prior Therapy
    The safety and efficacy of Bortezomib for Injection in relapsed or refractory mantle cell lymphoma were evaluated in an open-label, single-arm, multicenter study (NCT00063713) of 155 patients with progressive disease who had received at least one prior therapy. The median age of the patients was 65 years (42, 89), 81% were male, and 92% were Caucasian. Of the total, 75% had one or more extra-nodal sites of disease, and 77% were Stage 4. In 91% of the patients, prior therapy included all of the following: an anthracycline or mitoxantrone, cyclophosphamide, and rituximab. A total of thirty-seven percent (37%) of patients were refractory to their last prior therapy. An intravenous bolus injection of Bortezomib for Injection 1.3 mg/m 2/dose was administered twice weekly for two weeks on Days 1, 4, 8, and 11 followed by a ten day rest period (Days 12 to 21) for a maximum of 17 treatment cycles. Patients achieving a CR or CRu were treated for four cycles beyond first evidence of CR or CRu. The study employed dose modifications for toxicity [see Dosage and Administration (2.6, 2.7)] .

    Responses to Bortezomib for Injection are shown in Table 19. Response rates to Bortezomib for Injection were determined according to the International Workshop Response Criteria (IWRC) based on independent radiologic review of CT scans. The median number of cycles administered across all patients was four; in responding patients the median number of cycles was eight. The median time to response was 40 days (range: 31 to 204 days). The median duration of follow-up was more than 13 months.
