Bortezomib: A Review in Mantle Cell Lymphoma in Previously Untreated Patients Unsuitable for Stem-Cell Transplantation
- 356 Downloads
Bortezomib (Velcade®) is a proteasome inhibitor that is approved for the treatment of multiple myeloma and mantle cell lymphoma (MCL). This article reviews the efficacy and tolerability of bortezomib in combination with rituximab, cyclophosphamide, doxorubicin and prednisone (VR-CAP) in the treatment of previously untreated MCL unsuitable for stem-cell transplantation, and overviews the pharmacology of bortezomib. In the large, randomized, assessor-blinded, multinational LYM-3002 trial, induction therapy with VR-CAP improved progression-free survival significantly more than R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) after a median follow-up of 40 months in patients with newly diagnosed MCL ineligible or not considered for stem-cell transplantation. Complete response and certain other secondary endpoints were improved significantly more with VR-CAP than R-CHOP. Overall survival data were not mature at the time of assessment. The improved efficacy with VR-CAP was accompanied by an increased incidence of grade 3 or higher adverse events, particularly haematological adverse events.
