简要总结
Newly diagnosed Multiple Myeloma patients who are ineligible for a transplant have inferior outcomes to that of the transplant population. This is an area of high unmet need and calls for newer therapies with novel mechanisms of action to improve survival in this non-transplant eligible (NTE) group. Daratumumab is a monoclonal antibody that targets CD38 expressed at high levels on myeloma plasma cells. In phase 1/2 studies, it has demonstrated impressive single agent activity in relapse and refractory myeloma with a very acceptable toxicity profile. This set the stage for combinations with daratumumab to increase efficacy and improve outcomes of patients in both the relapse refractory and newly diagnosed settings. Two large Phase 2 trails using lenalidomide and dexamethasone or bortezomib and dexamethasone along with Daratumumab demonstarted the impressive efficacy of antibody based 3 drug combinations in the relapsed refractory myeloma setting. More recently a large clinical trial using a Bortezomib based 4 drug combination with Daratumumab was reported from Europe in the first-line treatment of transplant ineligible Myeloma patients showing very good survival outcomes. Hence the investigators hypothesize that the combination of Daratumumab with bortezomib and dexamethasone in the NTE population may therefore improve efficacy and clinical outcomes.
详细描述
Newly diagnosed Multiple Myeloma patients who ineligible for a transplant have inferior outcomes compared to that of the transplant population. This is an area of high unmet need and calls for newer therapies with novel mechanisms of action to better improve survival in this non-transplant eligible (NTE) group. Currently NTE patients will be treated with a Bortezomib based or Lenalidomide based doublet or triplet regimen as first-line.
Daratumumab is a monoclonal antibody that targets CD38 expressed at high levels on myeloma plasma cells. In phase 1/2 studies, it has demonstrated impressive single agent activity in relapse and refractory myeloma with a very acceptable toxicity profile and is a promising new treatment. This set the stage for combinations with daratumumab to increase efficacy and improve outcomes of patients in both the relapse refractory and newly diagnosed settings. Addition of daratumumab to any number of the backbone regimes have been shown to be of good efficacy. 2 phase 1 / 2 studies established the dosing regimen for Daratumumab as a single agent in patients who relapse after prior lenalidomide and bortezomib.
More recently, results from 2 randomised studies comparing Daratumumab plus lenalidomide and dexamethasone compared to lenalidomide and dexamethasone, and Daratumumab plus bortezomib and dexamethasone compared to bortezomib and dexamethasone, showed that the addition of Daratumumab significantly improved response and progression free survival, including a high minimal residual disease (MRD) negative rate of more than 20% in the relapse myeloma populations.
Another recent study showed that a different 4 drug combination of Daratumumab, bortezomib and Melphalan and Prednisolone in the front line setting of non-transplant Myeloma had promising response rates and was a quite tolerable combination.
All the above Daratumumab trials demostrated that deeper responses are achieved by antibody - Proteasome inhibitor or Antibody - ImiD combinations. It is known that deeper response in myeloma are associated with longer progression free and overall survival. Hence this trial using the three drug combination of Daratumumab, Bortezomib and Dexamethasone is proposed to explore its efficacy by demonstarting an improvement in overall response rates, complete response rates and to document its safety/tolerability in our population.
