Detailed Description

Multiple myeloma with plasmacytoma is a disease with significantly short overall survival. Cancer cells in plasmacytoma has inferior response compared to cancer cells in bone marrow in multiple myeloma. It is revealed that genetic difference such as CCND1 overexpression and RAS mutation exists between plasmacytoma and intramedullary plasma cell myeloma, implying different treatment strategy should be applied to overcome poor prognosis of this distinct disorder.

Even in the era of potent IMiDs and proteasome inhibitors, median overall survival of multiple myeloma patients with plasmacytoma is less than 5 years. Moreover, relapse in a form of soft tissue plasmacytoma is frequently observed after triplet combination treatment in multiple myeloma. Hence, multiple myeloma with plasmacytoma is a disease where unmet medical need still exists.

Biologically, plasmacytoma is characterized by high plasma cell proliferation, angiogenesis gene profile, and adhesion molecule changes mimicking solid tumor . Responsiveness to chemotherapy used in myeloma including IMIds5 and proteasome inhibitor6 is obtuse in plasmacytoma. Only small fraction of young patients receiving high-dose chemotherapy followed by autologous stem cell transplantation may overcome adverse prognostic impact of plasmacytomas . Even it is recommended that VTD-PACE would be used as the first line treatment for plasmacytomas.

In summary, cancer cells in plasmacytoma bear biologic characteristics of solid tumor cells and do respond to high-dose chemotherapy. And this phenomenon is very similar to lymphoma for the following reasons. Like lymphoma, 1) plasmacytoma express tumor antigen strongly (CD38 or CD138), 2) they form a solid mass, and 3) respond to cytotoxic chemotherapy in a dose-response manner.

Considering the success story of rituximab in lymphoma, we conjecture that daratumumab may work excellently to control plasmacytoma. Hence, we propose a treatment regimen consists of DCEP chemotherapy and daratumumab.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
