Spots Global Cancer Trial Database for Elotuzumab in Patients With Multiple Myeloma Before and After Peripheral Stem Cell Autologous Graft

Study Description

Brief Summary: This is a multicenter, open-label phase II study, assessing the efficacy of elotuzumab in elderly patients with multiple myeloma undergoing peripheral stem cell autologous graft

Detailed Description: In patients of 65 years of age or older, intensive treatment (TI) with hematopoietic stem cell autologous graft (ASCH) is not considered as the gold standard. Nowadays, given the rise of new treatments, new studies assessing TI with ASCH in elderly, seem required. The association bortezomib (VEL) - thalidomide (THAL) - dexamethasone (DEX) is considered as the standard induction (Kumar, Flinn et al. 2012, Ludwig, Viterbo et al. 2013). However, more and more strategies with immunotherapies are developed. Furthermore, it looks encouraging to use several monoclonal antibodies at different clinical development levels. Thus, elotuzumab (ELO) is an IgG1 (immunoglobulin gamma-1) (IgGκ) humanized monoclonal antibody directed against SLAMF7. SLAMF7 is a glycoprotein expressed by myeloma cells and natural killer (NK) but not by healthy tissues. Consequently, elotuzumab can kill specifically myeloma cells without affecting healthy tissues (Hsi, Steinle et al. 2008). A phase I study assessed the safety of ELO in association with VEL, REV (Lenalidomide) and DEX in induction first-line treatment in elderly patients with median age of 67 years (Usmani, Sexton et al. 2015). There were no significant increase of side effects with this association compared with side effects usually reported with VEL, REV and DEX. Thus, adding ELO could lead to an increase of response rate, with no increase of toxicity. For more than 10 years, the standard intensive treatment associates a MEL (MELPHALAN) conditioning (200 mg/m2) with a blood graft. In a recent study, almost all patients aged between 65-69 and 70-74 years received MEL at 200 mg/m2. The adverse events rate was similar between the different ages and a very low non-tied relapse mortality. Thus, in elderly patients selected, the use of MEL at 200 mg/m2 seems sure. Moreover, it's widely admitted that the conditioning treatment should be based on an efficient drugs association with a limited toxicity. Studies assessing consolidation treatment with an association of new drugs are limited. Initial results suggest that the use of new drugs after intensive treatment (IT) with ASCH should increase response rate and improve progression-free survival and global survival. The aim of this study IFM 2016-03 is to assess intensive treatment (IT) with AHSCT (Autologous hematopoietic stem cell transplantation) in elderly and to associate the different steps (induction, high dose conditioning, consolidation) with immunotherapy. Given the prior results of IFM and international studies, a VGPR (Very Good Partial Response) rate of around 85% is expected.
