The addition of cyclophosphamide to VRD in 25 patients with newly diagnosed myeloma led to a response rate of 96% (68% with at least a very good partial response), but 3 patients (12%) experienced neutropenic fever, which usually requires hospital admission.

This is a phase I/II study of VRD in 66 patients with newly diagnosed myeloma. MTD was found to be:
- Bortezomib 1.3 mg/m2 IV on days 1, 4, 8, 11
- Lenalidomide 25 mg PO qd on days 1-14
- Dexamethasone 20 mg PO on days 1,2, 4,5, 8,9, 11,12
Cycles were repeated every 21 days.
- Response rate was 100%. Complete remission: 57%. 74% of patients achieved VGPR or better.
- Maximal response was often achieved after 4 cycles
- Median collection yield was 5.6 million CD34+ cells/Kg (28 patients proceeded to stem cell transplant)
- After a median follow-up of 21 months, estimated 18-month progression-free survival was 75%, and overall survival 97%.
- Most common toxicities were peripheral neuropathy (80%) and fatigue (64%)
- Painful sensory neuropathy: 32%
- DVT rate was 6%
- 40% of patients required dose reductions, interruptions, or discontinuation of therapy because of toxicity

51 patients with relapsed myeloma underwent a RIC allogeneic SCT, using fludarabine 90-120 mg/m2 + melphalan 90-140 mg/m2. Results:
- Transplant-related mortality at 100 days: 12%
- Transplant-related mortality at 1 year: 25%
- Grade II/IV acute GVHD: 27%
- Grade II/IV chronic GVHD: 47%
- Progression-free survival at 2 years: 19%
- Overall survival at 2 years: 32%
- Long-term survivors in remission (presumed cure): 14%
N.B.: These patients were heavily pretreated, with a predicted life expectancy of only 8-12 months.

This is a retrospective study of 50 patients with relapsed/refractory myeloma treated with RIC allogeneic SCT. Stem cells were taken from a sibling (27 patients) or matched unrelated donors (23 patients). At a median follow-up of 6.4 years, progression-free survival was 26%, and overall survival 34%. Non-relapse mortality was 26%.

At the time of this publications, many myeloma experts believed that bortezomib overcame the negative impact of adverse cytogenetics in multiple myeloma. This study utilized bortezomib as primary therapy (i.e., induction x8 cycles, maintenance with 1 dose every other week, indefinitely, and salvage therapy - without stem cell transplantation) in patients with high-risk myeloma. Results:
- Response rate: 48%
- Median progression-free survival: 8 months (95% CI 6-12 months)
- Overall survival at 1 year: 88%
- Overall survival at 2 years: 76%

This is a double-blind study of 363 patients with newly diagnosed myeloma, randomized to receive MPT (melphalan 0.25 mg/Kg + prednisone 100 mg days 1-4 every 6 weeks, and thalidomide 100-400 mg PO qhs) vs MP + placebo. Results:
- Partial response was 34% with MPT and 33% with MP
- VGPR or better was 23% with MPT and 7% with MP (p <0.001)
- No difference in progression-free survival: 15 months with MPT and 14 months with MP (p= 0.16)
- No difference in overall survival: 29 months with MPT and 32 months with MP (p= 0.16)

This is a case-matched study of 72 patients with newly diagnosed myeloma, treated with BiRd or Rd. The retrospective analysis favored BiRd:
- Rate of complete response: 46% with BiRd and 14% with Rd (p <0.001)
- Median progression-free survival: 48.3 months with BiRd and 27.5 months with Rd (p= 0.044)
- Overall survival at 3 years: 90% with BiRd and 73% with Rd (only trend: p 0.17)
