History

In June 2019, polatuzumab vedotin-piiq was approved in the United States in combination with the chemotherapy bendamustine and a rituximab product (a combination known as "BR"), to treat adult patients with diffuse large B-cell lymphoma (DLBCL) that has progressed or returned after at least two prior therapies.[7] Polatuzumab vedotin is a novel antibody-drug conjugate, and DLBCL is the most common type of non-Hodgkin lymphoma.[7]

The U.S. Food and Drug Administration (FDA) granted accelerated approval to polatuzumab vedotin used in combination with the chemotherapy bendamustine and a rituximab product.[7] Further clinical trials are required to verify and describe the clinical benefit of polatuzumab vedotin.[7]

The FDA approved polatuzumab vedotin based primarily on evidence from one clinical trial (NCT02257567)[10] that was conducted in the United States, Canada, Europe, and Asia.[8] Patients who participated in the trial had lymphoma that came back or did not improve after prior treatment.[8]

The FDA granted the application of polatuzumab vedotin-piiq breakthrough therapy designation, priority review designation, and orphan drug designation.[7] The FDA granted the approval of Polivy to Genentech.[7]

Polatuzumab vedotin was approved for medical use in the European Union in January 2020 as a second-line treatment.[4] The European Medicines Agency (EMA) designated polatuzumab vedotin an orphan medicine in April 2018.[4] In March 2022, the European Medicines Agency's Committee for Medicinal Products for Human Use recommended Polatuzumab vedotin, in combination with R-CHP or R-CHOP, as a primary treatment.[11]
