Abstract
Despite continuous improvements in the management and treatment of diffuse large B-cell lymphoma (DLBCL), approximately 35% of affected patients experience relapse or are refractory to frontline chemotherapy. For these patients, outcomes are far from satisfactory, and a real unmet need exists both to improve frontline treatment and to create better options for relapsed/refractory disease. Polatuzumab vedotin is an anti-CD79b antibody conjugated to the monomethyl auristatin E microtubule inhibitor. The molecule has recently been under the spotlight for the promising results of the frontline combination with rituximab, cyclophosphamide, doxorubicin and prednisone in the phase III POLARIX study, demonstrating improved progression-free survival over standard rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone. Remarkable improvements in terms of complete response rate and overall survival have also been achieved with polatuzumab vedotin by combining the antibody with the standard rituximab and bendamustine regimen for relapsed/refractory patients. Based on the results of these studies, health authorities in several countries granted approval for polatuzumab vedotin to be used as treatment both for patients with previously untreated DLBCL and for those with relapsed/refractory DLBCL. In this review, we summarize the data of major studies recently concluded with polatuzumab vedotin, and we provide an overview of the ongoing combination trials for frontline and relapsed/refractory DLBCL, outlining reported toxicities.
期刊介绍:
Haematologica is a journal that publishes articles within the broad field of hematology. It reports on novel findings in basic, clinical, and translational research.
Scope:
The scope of the journal includes reporting novel research results that:
Have a significant impact on understanding normal hematology or the development of hematological diseases.
Are likely to bring important changes to the diagnosis or treatment of hematological diseases.
