Clinical and Economic Impact of Multiple Myeloma
The clinical and economic impact of multiple myeloma is tremendous. With the onset of novel therapies used in multiple myeloma, as well as the release of new data demonstrating progression-free survival and overall survival, therapy used in multiple myeloma is now on the radar for payers, despite the relatively low incidence of the disease.
In addition, contributing to the awareness of payers is the reality that maintenance therapy and multitherapy or combination regimens are becoming very common in the approach to treatment of patients with multiple myeloma. As a result of using newer agents, the 5-year survival rate has increased to 40% for patients diagnosed with this disease between 2001 and 2007.1,2
The data from the VISTA trial reported at the recent American Society of Hematology annual meeting and discussed in the article above are interesting and encouraging in their long-term perspective. The VISTA trial evaluated the safety and efficacy of melphalan and prednisone (MP) therapy versus bortezomib in combination with MP as initial therapy for nontransplant patients with multiple myeloma.3 In this trial, both the response rates and a marker for osteoblast activation (ie, alkaline phosphatase) were superior in the group of patients receiving bortezomib-based therapy compared with those receiving the MP regimen alone.
So far, the role of bortezomib in bone disease has not been demonstrated in patients in the transplant or relapsed setting. However, the ability to see long-term survival, with a follow-up period of 5 years, is particularly exciting in a condition that is without a cure. At 5 years mortality was reduced substantially, by more than 30%, in this patient population compared with the conventional first-line therapy with MP. These datawill help to continually shape appropriate guideline/protocol development.
