2.1 General Dosing Guidelines
The recommended starting dose of VELCADE is 1.3 mg/m2. VELCADE may be 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)].
VELCADE retreatment may be considered for patients with multiple myeloma who had previously responded to treatment with VELCADE and who have relapsed at least 6 months after completing prior VELCADE treatment. Treatment may be started at the last tolerated dose [see Dosage and Administration (2.6)].
When administered intravenously, VELCADE is administered as a 3 to 5 second bolus intravenous injection. VELCADE is for intravenous or subcutaneous use only. VELCADE should not be administered by any other route.
Because each route of administration has a different reconstituted concentration, caution should be used when calculating the volume to be administered.
2.2 Dosage in Previously Untreated Multiple Myeloma
VELCADE is administered in combination with oral melphalan and oral prednisone for nine 6-week treatment cycles as shown in Table 1. In Cycles 1-4, VELCADE is administered twice weekly (days 1, 4, 8, 11, 22, 25, 29 and 32). In Cycles 5-9, VELCADE is administered once weekly (days 1, 8, 22 and 29). At least 72 hours should elapse between consecutive doses of VELCADE.
