The combination chemotherapy regimen VDT PACE and its variations are effective in patients intensely pre-treated for relapsed/refractory multiple myeloma, according to an intent-to-treat analysis involving 141 individuals. Participants had relapsed/refractory multiple myeloma and were treated with VDT PACE-like regimens (VLPRs) at a single center between 2006 and 2017. They received a median of 4 prior treatments. ~Two-thirds had prior stem cell transplant (SCT). ~Half had high-risk cytogenetics. Among the results:
- ~7 in every 10 patients achieved ≥minimal response.
- 54% achieved ≥partial response.
- 1 in every 10 achieved ≥very good partial response.
- Median progression-free and overall survival were 3.1 and 8.1 months, respectively.
- 8 in every 10 received therapy after VPLR; 63% received systemic chemotherapy and 39% SCT.
- Those who received SCT survived a median of 5.1 months.
- Patients ≥60 years of age and those with R-ISS III stage experienced shorter overall survival.
