Polatuzumab Vedotin, Rituximab, Ifosfamide, Carboplatin, and Etoposide (PolaR-ICE) as Initial Salvage Therapy for the Treatment of Relapsed/Refractory Diffuse Large B-Cell Lymphoma

Purpose

This phase II trial studies the effect of polatuzumab vedotin, rituximab, ifosfamide, carboplatin, and etoposide as initial salvage therapy in treating patients with diffuse large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Polatuzumab vedotin is a monoclonal antibody, polatuzumab, linked to a toxic agent called vedotin. Polatuzumab attaches to CD79b positive cancer cells in a targeted way and delivers vedotin to kill them. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Chemotherapy drugs, such as ifosfamide, carboplatin, and etoposide, 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 chemotherapy with immunotherapy may kill more cancer cells in patients with diffuse large B-cell lymphoma.

If hepatic involvement by lymphoma, or Gilbert's disease: =< 3 X ULN - Aspartate aminotransferase (AST) =< 2.5 x ULN. If hepatic involvement by lymphoma: AST =< 5 x ULN - Alanine aminotransferase (ALT) =< 2.5 x ULN. If hepatic involvement by lymphoma: ALT =< 5 x ULN - Creatinine clearance of >= 50 mL/min per 24 hour urine test or the Cockcroft-Gault formula - If not receiving anticoagulants: international normalized ratio (INR) OR prothrombin (prothrombin time [PT]) =< 1.5 x ULN. If on anticoagulant therapy: PT must be within therapeutic range of intended use of anticoagulants - If not receiving anticoagulants: activated partial thromboplastin time (aPTT) =< 1.5 x ULN. If on anticoagulant therapy: aPTT must be within therapeutic range of intended use of anticoagulants - Women of childbearing potential (WOCBP): negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required - Agreement by females and males of childbearing potential* to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 12 months after the last dose of polatuzumab vedotin or rituximab for women, at least 5 months following the last dose of polatuzumab vedotin or 3 months following the last dose of rituximab for men, and at least 6 months following the last dose of ifosfamide, carboplatin, or etoposide for both women and men - Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for > 1 year (women only)
Exclusion Criteria:
  1. - Patients who are not hematopoietic stem cell transplant candidates are excluded - Prior solid organ transplantation - Systemic steroid therapy or any other form of immunosuppressive therapy for lymphoma symptom control must be tapered down to =< 10 mg/day prednisone or equivalent. Exceptions are: - Inhaled or topical steroids - Adrenal replacement doses > 10 mg daily prednisone equivalents in the absence of active autoimmune disease - Peripheral neuropathy >= grade 2 or demyelinating form of Charcot-Marie-Tooth disease - Known active central nervous system (CNS) involvement by lymphoma, including leptomeningeal involvement - Active infection requiring systemic therapy - Other active malignancy requiring therapy. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer - History of severe allergic reactions attributed to compounds of similar chemical or biologic composition to study agents - Recent major surgery (within 4 weeks) prior to start of protocol therapy, other than for diagnosis - Symptomatic cardiac disease (including symptomatic ventricular dysfunction, symptomatic coronary artery disease, and symptomatic arrhythmias), cerebrovascular event/stroke or myocardial infarction within the past 6 months - Known active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. Patients with past HBV infection (defined as negative hepatitis B surface antigen [HBsAg] and positive hepatitis B core antibody [HBcAb]) are eligible if HBV DNA is undetectable. Patients who are positive for HCV antibody are eligible if polymerase chain reaction (PCR) is negative for HCV ribonucleic acid (RNA). Testing to be done only in patients suspected of having infections or exposures - Known active human immunodeficiency virus (HIV) infection. Subjects who have an undetectable or unquantifiable HIV viral load with CD4 >= 200 and are on highly active antiretroviral therapy (HAART) medication are allowed. Testing to be done only in patients suspected of having infections or exposures - History of or current progressive multifocal leukoencephalopathy (PML) - Females only: Pregnant or breastfeeding - Any other condition that would, in the investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures - Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
