Polatuzumab vedotin

Polatuzumab vedotin is a CD79b-directed antibody-drug conjugate that delivers monomethyl auristatin E (MMAE), an anti-mitotic agent, to cancer cells. The drug consists of three components - a humanized immunoglobulin G1 (IgG1) monoclonal antibody specific for human CD79b (polatuzumab), MMAE, and protease-cleavable linker called maleimidocaproyl-valine-citrulline-p-aminobenzyloxycarbonyl (mc-vc-PAB) that covalently attaches MMAE to polatuzumab. Polatuzumab vedotin was granted accelerated FDA approval on June 10, 2019 and was approved by Health Canada on July 9, 2020.

Polatuzumab vedotin is used in combination with bendamustine and rituximab to treat adult patients with relapsed or refractory diffuse large B-cell lymphoma, not otherwise specified, after at least two prior therapies. In Canada, this indication is approved for patients who are not eligible for autologous stem cell transplant and have received at least one prior therapy. Polatuzumab vedotin is also used in combination with rituximab, cyclophosphamide, doxorubicin, and prednisone (R-CHP) to treat adult patients with previously untreated large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (NOS), high-grade B-cell lymphoma, Epstein-Barr virus-positive (EBV+) DLBCL NOS, and T-cell/histiocyte rich LBCL.
