VMP Regimen - Safety, Efficacy, and Optimal Dose Finding Study for Patients With Multiple Myeloma

The 3-drug therapy of Bortezomib-Melphalan-Prednisolone (VMP) is a standard therapy that is commonly used currently in South Korea as a first-line treatment for treatment-naïve patients with multiple myeloma who are ineligible for hematopoietic transplantation. Despite the fact that VMP therapy is outstanding in terms of cost-effectiveness, treatment discontinuation rates due to adverse drug reactions is high. In addition, when considering that the percentage of elderly patients aged 70 years or above in the target patient group is 20% or above, there have been attempts to devise a plan that can decrease side effects while maintaining effectiveness. For example, there have been previous reported cases of overseas applications of modified VMP therapies with reduced doses, but they have applied various combinations in terms of the total cycles, administration intervals, doses, etc. This study was planned to evaluate the overall safety and efficacy of VMP therapy by following up on the actual VMP therapies applied in domestic clinics, patient characteristics, side effect occurrences, administration discontinuation rates, survival data, etc., as well as to collect exploratory data for a more effective study of modified VMP therapies.
