At the end of this time, subjects will be re-evaluated for the appropriateness of receiving a 3rd and 4th cycle of bortezomib. Bortezomib will be given subcutaneously (under the skin). If unable to give subcutaneously, bortezomib will be given as a single IV (injection into vein) over a time of 3 to 5 seconds. Patients will receive up to 4, four-dose cycles of 1.3 mg/m(2) (based on body surface area)."
