Padcev (Enfortumab Vedotin)

Padcev™ (enfortumab vedotin) is a treatment option for some patients with locally advanced or metastatic bladder cancer.

How does Padcev work?

Enfortumab vedotin targets specific cancer cells by locking onto the Nectin-4 molecule often found in bladder cancers. It is called a Nectin-4-directed antibody and microtubule inhibitor conjugate, which means it combines an antibody with a chemotherapy medication. The antibody portion helps to find and attach to the bladder cancer cells containing the Nectin-4 molecule. Once attached, the chemotherapy portion is released to attack the cancer cell.1

Who can receive Padcev?

Enfortumab vedotin may be used in the treatment of patients with locally advanced or metastatic bladder cancer who received prior treatment with either a PD-1 inhibitor or a PD-L1 inhibitor (forms of immunotherapy), and platinum-based chemotherapy. It may also be used to treat patients with locally advanced or metastatic bladder cancer who are unable to receive cisplatin chemotherapy and have already received at least one previous treatment. Locally advanced typically means the cancer has spread beyond the bladder within the bladder region (i.e. to nearby lymph nodes) or has become too large to be removed by surgery. Metastatic means the cancer cells have spread to other parts of the body.
