Bortezomib in multiple myeloma: a practice guideline.

Bortezomib (Velcade™, PS-341), a first-in-class proteasome inhibitor, has been extensively studied either alone or in combination with other agents for the treatment of multiple myeloma. We created a provincial guideline for the use of bortezomib, in newly diagnosed individuals (both eligible and ineligible for transplant) and in individuals with relapsed or refractory multiple myeloma.
