Summary

Toward improving the therapeutic index of standard TT3 (S-TT3), the investigators will employ a randomized Phase III trial design to determine whether S-TT3 treatment-related toxicities can be reduced by 50% in TT3-Lite (L-TT3). Note: Randomization has been discontinued and accrual is closed to the L-TT3 arm. This trial is currently enrolling as a single-arm trial for patients to receive S-TT3.

Detailed description

The major treatment-related toxicities in TT3 pertained to the high-dose melphalan 200mg/m2 (MEL200)-based tandem transplant approach, consisting of mucosal and other toxicities. For the TT4 trial, we are proposing to compare standard TT3 (S-TT3) to TT3-Lite (L-TT3). L-TT3 will employ various strategies aimed at improving the therapeutic Index of S-TT3 by reducing toxicities while maintaining the superior results reported for S-TT3 in terms of frequency and duration of CR, EFS, and. The following strategies will be utilized in L-TT3: * Applying only 1 instead of 2 cycles of induction and consolidation therapy prior to and after tandem transplant. This is supported by the well known association between prior exposure to mucotoxic therapies4, 5 and worse post-transplant mucositis, particularly when etoposide is used in the mobilizing regimen6 such as in VDTPACE. Note: Randomization has been discontinued and accrual is closed to the L-TT3 arm. This trial is currently enrolling as a single-arm trial for patients to receive S-TT3.

Conditions

• Multiple Myeloma

Interventions

Type	Name	Description
DRUG	M-VTD-PACE	2 cycles of induction therapy with M-VTD-PACE and PBSC collection after the 1st cycle. MEL-based tandem transplant will be administered 6 weeks to 3 months apart, applying single dose MEL 200 mg/m2 with adjustments for age and renal function. Consolidation will consist of 2 cycles of dose-reduced VTD-PACE. Maintenance treatment will employ VRD for 3 years.
DRUG	TT3-LITE Regimen (L-TT3)	The TT3-LITE Regimen (L-TT3) will employ only 1 cycle of induction therapy with MVTD-PACE and, as in S-TT3, PBSC collection following recovery from this one and only induction treatment. MEL-based tandem transplant will be administered 6 weeks to 3 months apart, applying fractionated MEL200mg/m2 in 4 successive daily fractions of 50mg/m2 (MEL50 x 4) with addition of VTD with adjustments for age and renal function. Consolidation will consist of only 1 cycle of dose-reduced VTD-PACE. Maintenance treatment will employ VRD for 3 years.
