This study compares outcomes of stem cell collections in 123 myeloma patients who underwent the collection within 1 year of starting therapy with novel agents. Mobilization regimen was:
  - Low-dose cyclophosphamide, 1.5/m2 + G-CSF (68 patients)
  - Intermediate-dose cyclophosphamide, 3-4 g/m2 + G-CSF (55 patients)
Stem cell yield was superior in patients who received intermediate-dose cyclophosphamide (16.6 vs 7.5 million CD34+ cells/Kg).

This is a phase 3 study which randomized patients with newly diagnosed myeloma treated with tandem autologous transplants into 2 groups:
  - TD group (161 patients) : Thalidomide and Dexamethasone during induction and maintenance therapy
  - VTD group (160 patients): Bortezomib, Thalidomide, and Dexamethasone during induction and maintenance therapy
Patients treated with VTD has better outcomes:
  - CR/nCR rate was 61% with TD and 73% with VDT
  - Progression-free survival at 3 years was 48% with TD and 60% with VDT
  - Overall survival was similar, but this could be due to short follow-up (median follow-up was 30 months), or to the effect of different salvage therapies

A phase 2 study of pegylated liposomal doxorubicin, bortezomib, dexamethasone and lenalidomide for patients with relapsed/refractory multiple myeloma.
Leukemia. 2012 Jul;26(7):1675-80.
Berenson JR, Yellin O, Kazamel T, Hilger JD, Chen CS, Cartmell A, Woliver T, Flam M, Bravin E, Nassir Y, Vescio R, Swift RA.
This is a phase II trial of 40 patients with relapsed/refractory myeloma patients, treated with:
  - Bortezomib 1.0 mg/m2 IV on days 1, 4, 8, 11
  - Liposomal doxorubicin 4 mg/m2 IV on days 1, 4, 8, 11
  - Dexamethasone 40 mg on days 1, 4, 8, 11
  - Lenalidomide 10 mg on days 1-14
Cycles were repeated every 28 days.
Clinical benefit was about 85%: Minimal response 36%, PR 18%, VGPR 10%, CR 20%.

Superiority of the Triple Combination of Bortezomib-Thalidomide-Dexamethasone Over the Dual Combination of Thalidomide-Dexamethasone in Patients With Multiple Myeloma Progressing or Relapsing After Autologous Transplantation: The MMVAR/IFM 2005-04 Randomized Phase III Trial From the Chronic Leukemia Working Party of the European Group for Blood and Marrow Transplantation.

The triple combination Bortezomib + Thalidomide + Dexamethasone (VTD) was superior to Thalidomide + Dexamethasone (TD) in 296 patients with myeloma relapsing after autologous stem cell transplantation:
  - Rate of CR/nCR: 45% with VTD and 25% with TD
  - Median progression-free survival was 19.5 months with VTD and 13.8 months with TD
  - 2-year survival: 71% with VTD and 65% with TD
The editorial article accompanying this study underscores the fact that these results are the best seen among all phase III studies for refractory myeloma, because the progression-free survival of all previously published studies was less than 12 months.

In this study, 53 patients with newly diagnosed myeloma were treated with CRD:
  - Carfilzomib 20-36 mg/m2 IV on days 1,2, 8,9, 15,16 (1,2, 15,16 after cycle 8)
  - Revlimid 25 mg PO on days 1-21
  - Dexamethasone 20-40 mg PO once a week
Cycles were repeated every 28 days. 36 patients underwent stem cell transplantation. Median follow-up was 13 months.
Results: at least nCR 62%, stringent CR 42%. Progression-free survival at 2 years was 92%.

827 patients with newly diagnosed myeloma were randomized to:
  - VAD (vincristine, doxorubicin, dexamethasone), autologous transplant, maintenance with thalidomide 50 mg daily (group A)
  - PAD (bortezomib, doxorubicin, dexamethasone), autologous transplant, maintenance with PAD every 2 weeks for 2 years
Progression-free survival was 28 months in group A and 35 months in group B.
In patients with 17p-, PFS was 12 months in group A and 22 months in group B.
