Venetoclax Plus R-ICE Chemotherapy for Relapsed/Refractory Diffuse Large B-Cell Lymphoma

The purpose of this study is to determine the correct dose and safety of adding a new cancer drug, venetoclax, to a standard combination of chemotherapy drugs as a second treatment for relapsed/refractory DLBCL. In this study, venetoclax will be added to RICE (rituximab, ifosfamide, carboplatin, etoposide), a common set to cancer drugs used as a second line treatment for relapsed/refractory DLBCL. Venetoclax, is a new targeted anti-cancer drug, which works by mimicking a particular protein produced by the tumor and interrupting its normal processes, ultimately causing the tumor cells to die. Adding venetoclax to the standard RICE regimen is believed to increase the chance of getting cancer into remission. Venetoclax is experimental because it is not approved by the Food and Drug Administration (FDA) for the treatment of relapsed/refractory DLBCL. Venetoclax has been FDA approved for use in patients with chronic lymphocytic leukemia (CLL).
