UARK 2003-33, Total Therapy III
There have been two previous Total Therapy studies for multiple myeloma (MM) at the Myeloma Institute for Research and Therapy (MIRT): Total Therapy I (from 1989 through 1994) and Total Therapy II (from 1996 to 2004). Results have shown that patients treated on these studies had better outcomes (meaning patients have lived longer and had better responses to treatment) when compared to patients treated with standard chemotherapy.
With this new study, Total Therapy III, researchers will take what they have learned from the first two studies and add new treatment strategies to try to improve the outcomes even more, especially for patients with chromosome abnormalities.

|Official Title:||A Phase 2 Study Incorporating Bone Marrow Microenvironment (ME) Co-Targeting Bortezomib Into Tandem Melphalan-Based Autotransplants With DT PACE for Induction/Consolidation and Thalidomide + Dexamethasone for Maintenance|
- Progression-Free Survival (PFS) at 3 Years From Initiation of Study Treatment. [ Time Frame: 3 years ] [ Designated as safety issue: No ]In patients with no confirmed Partial Response, Near Complete Response, or Complete Response, progression was defined as a >25% increase from baseline in myeloma protein production or other signs of disease progression such as hypercalcemia, etc. PFS was measured as the time from initial registration to progression/relapse of disease or death from any cause.

Experimental: Study Treatment
Two cycles of VDTPACE induction (Velcade days 1, 4, 8, and 11; DTPACE days 4-7) with interim thalidomide (50 mg QD) + Dex (20 mg QD x 4 days every 21 days) following each cycle. Induction followed by single or tandem MEL200 transplant (MEL140 mg/m2 for subjects > 70 years of age) with interim thalidomide (100mg QD) + Dex (20 mg QD x 4 days every 21 days) following each transplant. Transplants followed by two cycles of VDTPACE consolidation (Velcade days 1, 4, 8, and 11; DTPACE days 1-4) with interim thalidomide (100mg QD) + Dex (20 mg QD x 4 days every 21 days) following each cycle of VDTPACE. Consolidation followed by 3 years of maintenance therapy with VDT (velcade 1.0 mg/m2 days 1, 4, 8, 11 q 28 days; Thal 100 mg QD; and Dex 20mg days 1-4 and 8-11 q 28 days) during Year 1 and TD (Thal 100 mg QD and Dex 20 mg days 1-4, q 28 days) or VTD (velcade 1.0 mg/m2 weekly, Thal 100 mg QD, and Dex 20 mg weekly) during Years 2 and 3.
Two cycles of induction on days 1,4,8,11 at 1.0mg/m^2. Two cycles of consolidation on days 1,4,8,11 at 1.0mg/m^2. Maintenance year one 1.0mg/m^2 1,4,8,11 q 28 days.Drug: Thalidomide
Two cycles of VDTPACE 200mg thal days 4-7(cycle 1)and days 1-4 cycle 2 interim Thal 50mg qd between VTDPACE cycles and between cycle 2 and transplant. Thal 100mg between transplants d/c 7 days prior to each transplant. Consolidation therapy cycles 3 and 4 VDTPACE 200mg days 1-4 both cycles. Interim maintenance to maintenance 100mg qd. Maintenance year 1 thal 100mg qd. Maintenance years 2 and 3 Thal 100mg qd.
1.1 To determine, in a historical comparison with TT II (Thalidomide arm), whether two cycles of VDTPACE induction (instead of four induction cycles in TT II) followed by more timely MEL 200-based transplant with DEX + THAL between transplants can:
1.1.1 Increase the CR frequency from 50% to 60% at 18 months from initiation of therapy;
1.1.2 Increase > n-CR rate pre-transplant #1 from 20% to 40%;
1.1.3 Raise 2-year EFS rates from 55% to 75% in patients with CA and from 80% to 95%, in patients without CA.
