Diffuse Large B-Cell lymphoma (DLBCL) is the most commonly diagnosed form of non-Hodgkin lymphoma (NHL) in adults. Most patients receive an initial treatment with chemo-immunotherapy, which includes rituximab, cyclophosphamide, vincristine, doxorubicin and prednisone (R-CHOP). Cure rates are high but those who relapse, or do not respond to initial therapy, have a poor prognosis. Polatuzumab vedotin, an anti-CD79b monoclonal antibody conjugated to the cytotoxic payload monomethyl aurostatin-E (MMAE), in combination with bendamustine and rituximab (polatuzumab-BR) is a new, effective therapeutic option to add to the treatment of relapsed/refractory (R/R) DLBCL.
This review covers the clinical development of polatuzumab for the treatment of lymphoma, its current and future use in patients with DLBCL and identifies its place in the treatment of R/R DLBCL. A search of PubMed and oncology/hematology congresses using 'polatuzumab' as the search term was undertaken to identify the most pertinent clinical reports.
Polatuzumab-BR is an effective and safe option for transplant-ineligible patients with R/R DLBCL either before or after CAR-T (chimeric antigen receptor T-cell therapy). Ongoing combination trials with polatuzumab will expand its applications in the treatment of this disease.
弥漫性大B细胞淋巴瘤(DLBCL)是成人非霍奇金淋巴瘤(NHL)中最常见的诊断形式。大多数患者接受包括利妥昔单抗、环磷酰胺、长春新碱、阿霉素和泼尼松(R-CHOP)的化疗免疫疗法进行初始治疗。治愈率很高,但那些复发或对初始治疗无反应的患者预后较差。泊洛妥珠单抗维达汀是一种与细胞毒性载荷单甲基奥司他丁-E(MMAE)偶联的抗CD79b单克隆抗体,与苯达莫司汀和利妥昔单抗联合使用(泊洛妥珠单抗-BR)是一种新的、有效的治疗选择,可用于复发/难治性(R/R)DLBCL的治疗。
本综述涵盖了泊洛妥珠单抗治疗淋巴瘤的临床进展、其在DLBCL患者中的当前及未来应用,并确定了其在R/R DLBCL治疗中的地位。以“泊洛妥珠单抗”为检索词,检索了PubMed和肿瘤学/血液学大会,以确定最相关的临床报告。
泊洛妥珠单抗-BR对于不符合移植条件的R/R DLBCL患者,无论是在嵌合抗原受体T细胞疗法(CAR-T)之前还是之后,都是一种有效且安全的选择。正在进行的泊洛妥珠单抗联合试验将扩大其在该疾病治疗中的应用。
