Enfortumab Vedotin-EJfv (Padcev): Uses, Side Effects, and Patient Information

What is Enfortumab Vedotin-ejfv (Padcev)?

Enfortumab vedotin-ejfv, sold under the brand name Padcev, is an antineoplastic agent used for the treatment of locally advanced or metastatic urothelial cancer that has progressed after treatment with platinum-containing chemotherapy.

Padcev is a monoclonal antibody that targets Nectin-4, a protein expressed on the surface of urothelial cancer cells. It is conjugated with vedotin, a microtubule-disrupting agent, which helps in the destruction of cancer cells.

Approved Uses of Padcev

In April 2020, the U.S. Food and Drug Administration (FDA) approved Padcev for the treatment of adults with locally advanced or metastatic urothelial cancer who have previously been treated with a platinum-containing chemotherapy and, in some cases, other types of therapy.

How Padcev Works

The mechanism of action of Padcev is unique. The monoclonal antibody part of the drug binds to Nectin-4 on the cancer cells, and the vedotin part then releases its toxic payload into the cells. This disrupts the microtubule network, which is essential for cell division, ultimately leading to cell death.

Side Effects of Padcev

As with any medication, Padcev can cause side effects. Some common side effects include:

• Pneumonitis: Inflammation of the lungs, which can be serious and potentially lead to death.
• Neuropathy: Nerve damage that can cause pain, burning, tingling, or numbness in the hands and feet.
• Bladder toxicity: Symptoms can include blood in the urine, frequent urination, and pain or burning during urination.
• Increased liver enzymes: This may indicate liver damage.
• Other side effects: Fatigue, decreased appetite,脱发, nausea, and constipation are also possible.

It's important for patients to discuss all potential side effects with their healthcare provider before starting treatment.

How to Take Padcev

Padcev is administered via intravenous infusion. The recommended dose is 1.25 mg/kg given over an hour, every week. Treatment continues until the disease progresses or side effects become intolerable.

Patients should not eat for at least 2 hours before and 1 hour after receiving Padcev.

Precautions and Warnings

Before taking Padcev, patients should inform their healthcare provider if they have any allergies, liver or kidney disease, or a history of lung or breathing problems.

Women who are pregnant or breastfeeding should not take Padcev, as it may harm the baby. Effective birth control is recommended during treatment and for a period after the last dose.

Drug Interactions

Padcev may interact with other medications, including certain cancer drugs. It's important to inform the healthcare provider about all other medications being taken.

Research and Future Uses

Ongoing research is investigating the effectiveness of Padcev in combination with other cancer treatments. There is also interest in exploring its use for other types of cancer that express Nectin-4.

Conclusion

Enfortumab vedotin-ejfv (Padcev) represents an important advancement in the treatment of urothelial cancer. Its targeted approach offers a new option for patients whose cancer has not responded to other treatments. As with any cancer therapy, it is important for patients to be aware of the potential benefits and risks and to work closely with their healthcare providers to make informed decisions about their care.
