VELCADE®▼3.5 mg POWDER FOR SOLUTION FOR INJECTION PRESCRIBING INFORMATION ACTIVE INGREDIENT: Bortezomib
Please refer to Summary of Product Characteristics (SmPC) before prescribing. INDICATION(S): Monotherapy of progressive multiple myeloma in patients who have had at least 1 prior therapy and already undergone or are not suitable for bone marrow transplantation. With melphalan & prednisolone for treating previously untreated multiple myeloma patients who are not eligible for high-dose chemotherapy with bone marrow transplant. DOSAGE & ADMINISTRATION:Adults and Elderly: Starting dose 1.3mg/m2 body surface area Monotherapy: twice weekly via intravenous injection for two weeks followed by a 10-day rest period. When administered as a single agent, treatment should be withheld in the presence of any Grade 3 non-haematological or Grade 4 haematological toxicity, excluding neuropathy. Treatment may be restarted at an approximate 25% dose reduction (1.3 mg/m2 reduced to 1.0 mg/m2; 1.0 mg/m2 reduced to 0.7 mg/m2) following resolution of toxicity. The dose should be reduced to 1 mg/m2 in the presence of Grade 1 with pain or Grade 2 (interfering with function but not with activities of daily living) neuropathy. In the presence of Grade 2 with pain or Grade 3 (interfering with activities of daily living) neuropathy, treatment should be withheld until symptoms of toxicity have resolved. Reinitiate treatment at a dose of 0.7 mg/ m2 and reduce dosing schedule to weekly. If Grade 4 neuropathy and /or severe autonomic neuropathy occur, discontinue treatment permanently. Combination therapy: administered via intravenous injection in combination with oral melphalan (9mg/m2) and prednisolone (60mg/m2) for nine 6-week treatment cycles. Refer to SmPC for dose management. Reconstituted solution given as 3-5 second IV bolus. When administered in combination with melphalan and prednisone, treatment should be withheld if either the platelet counts ≤30 × 109/l or ANC ≤0.75 x 109/l on a VELCADE dosing day (other than Day 1). Consideration should be given to reducing subsequent doses by 1 dose level (from 1.3 mg/m2 to 1 mg/m2, or from 1 mg/m2 to 0.7 mg/m2) if several doses (≥ 3 doses during twice weekly administration or ≥ 2 doses during weekly administration) are withheld in any one cycle of treatment. Treatment should be withheld until any ≥Grade 3 non-haematological toxicities have returned to Grade 1 or baseline. Retreatment should be initiated with one dose level reduction. During combination therapy the dose should be held and/or modified in the presence of VELCADE-related neuropathic pain and/or peripheral neuropathy in the same way as monotherapy. Children: Not applicable. Hepatic Impairment: mild - no dose adjustment; moderate or severe - start on reduced dose of 0.7 mg/m2 per injection for first cycle, and then possible increase to 1.0 mg/m2 or reduction to 0.5 mg/m2 based on tolerability. Renal Impairment: See precautions. CONTRAINDICATIONS: Hypersensitivity to bortezomib, boron or any of the excipients. Acute diffuse infiltrative pulmonary and pericardial disease. SPECIAL WARNINGS & PRECAUTIONS: Monitor complete blood counts including platelets. Gastrointestinal toxicity is very common, monitor closely. Peripheral
neuropathy is common and requires careful monitoring. Patients should undergo neurological evaluation and possible dose modification. Special care of patients with risk factors for seizures. Caution is advised when history of syncope on receiving medicinal products known to be associated with hypotension; or who are dehydrated due to recurrent diarrhoea or vomiting. Discontinue treatment if Reversible Posterior Leukoencephalopathy Syndrome occurs. Development or exacerbation of congestive heart failure, QT prolongation. Monitor closely patients with cardiac risk factors and those with renal impairment. Rare reports of acute diffuse infiltrative pulmonary disease of unknown aetiology eg pneumonitis, interstitial pneumonia, lung infiltration and acute respiratory distress syndrome (ARDS). A baseline pretreatment chest radiograph is recommended. In event of new or worsening pulmonary symptoms perform prompt diagnostic evaluation and treat appropriately. Consider benefit/risk ratio before continuing VELCADE therapy. Immunocomplex-mediated reactions eg serum sickness, polyarthritis with rash, proliferative glomerulonephritis: discontinue if severe. Bortezomib exposure is increased in moderate/severe hepatic impairment; treat at reduced doses and closely monitor for toxicities. Patients with high pre-treatment tumour burden are at risk of tumour lysis syndrome; monitor closely. Monitor patients closely when given concomitant CYP3A4-inhibitors. Exercise caution when combined with CYP3A4- or CYP2C19 substrates.

INTERACTIONS: Patients should be closely monitored when given bortezomib in combination with potent CYP3A4-inhibitors (e.g. ketoconazole, ritonavir).
Concomitant use of bortezomib with strong CYP3A4 inducers (e.g., rifampicin, carbamazepine, phenytoin, phenobarbital and St. John's Wort), is not recommended, In vitro studies indicate that bortezomib is a weak inhibitor of the cytochrome P450 (CYP) isozymes 1A2, 2C9, 2C19, 2D6 and 3A4. No clinically relevant interaction between melphalan-prednisolone and VELCADE. In clinical trials, hypo/hyperglycaemia were reported in diabetic patients receiving oral hypoglycaemics.
