• Peripheral Neuropathy: Manage with dose modification or discontinuation. Patients with pre-existing severe neuropathy should be treated with Bortezomib only after careful risk-benefit assessment. - Hypotension: Use caution when treating patients taking anti hypertensives, with a history of syncope, or with dehydration. - Cardiac Toxicity: Worsening of and development of cardiac failure has occurred. Closely monitor patients with existing heart disease or risk factors for heart disease. - Pulmonary Toxicity: Acute respiratory syndromes have occurred. Monitor closely for new or worsening symptoms and consider interrupting Bortezomib therapy. - Posterior Reversible Encephalopathy Syndrome: Consider MRI imaging for onset of visual or neurological symptoms; discontinue Bortezomib if suspected. - Gastrointestinal Toxicity: Nausea, diarrhea, constipation, and vomiting may require use of antiemetic and antidiarrheal medications or fluid replacement. - Thrombocytopenia and Neutropenia: Monitor complete blood counts regularly throughout treatment. - Tumor Lysis Syndrome: Closely monitor patients with high tumor burden. - Hepatic Toxicity: Monitor hepatic enzymes during treatment. Interrupt Bortezomib therapy to assess reversibility. - Thrombotic Microangiopathy: Monitor for signs and symptoms. Discontinue Bortezomib if suspected. - Embryo-Fetal Toxicity: Bortezomib can cause fetal harm. Advise females of reproductive potential and males with female partners of reproductive potential of the potential risk to a fetus and to use effective contraception. 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. 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.

The following clinically significant adverse reactions are also discussed in other sections of the labeling: - Peripheral Neuropathy - Hypotension - Cardiac Toxicity - Pulmonary Toxicity - Posterior Reversible Encephalopathy Syndrome (PRES) - Gastrointestinal Toxicity - Thrombocytopenia/Neutropenia - Tumor Lysis Syndrome - Hepatic Toxicity - Thrombotic Microangiopathy Most commonly reported adverse reactions (incidence ≥ 20%) in clinical studies include nausea, diarrhea, thrombocytopenia, neutropenia, peripheral neuropathy, fatigue, neuralgia, anemia, leukopenia, constipation, vomiting, lymphopenia, rash, pyrexia, and anorexia. 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 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.
