A Multicenter, Open-Label Feasibility Study of Daratumumab With Dose-Adjusted EPOCH in Newly Diagnosed Plasmablastic Lymphoma With or Without HIV
AIDS Malignancy Consortium
Summary
This feasibility trial studies how well daratumumab in combination with dose-adjusted etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride (DA-EPOCH) works in treating patients with newly diagnosed stage I-IV plasmablastic lymphoma. Plasmablastic lymphoma cells have high levels of a protein called CD38. Daratumumab is a monoclonal antibody that specifically targets CD38 expressing cells, and may help the body's immune system attack the cancer and interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving daratumumab may enhance the effectiveness of a standard chemotherapy (DA-EPOCH) in patients with plasmablastic lymphoma.
Description
PRIMARY OBJECTIVES: 1\. To evaluate the feasibility of adding daratumumab to DA-EPOCH by assessing the percentage of PBL patients who complete ≥3 cycles of study treatment per protocol. SECONDARY OBJECTIVES: 1. To estimate the complete response (CR) rate as defined by the 2017 RECIL Criteria in HIV positive and HIV negative patients with plasmablastic lymphoma treated with daratumumab and DA-EPOCH. 2. To evaluate the safety of dose-adjusted EPOCH with daratumumab as assessed by the NCI CTCAE version 5.0. 3. To estimate the overall survival (OS), progression free survival (PFS), and event fr…
