Polatuzumab vedotin

Polatuzumab vedotin is an antibody-drug conjugate targeting CD79b. It contains a humanized anti-CD79b IgG1 monoclonal antibody linked to monomethyl auristatin E (MMAE), a potent microtubule inhibitor. Polatuzumab vedotin has the potential for the research of Large B-cell lymphomas (LBCL)[1].
