What side effects are associated with this type of intervention?

Enfortumab Vedotin, an antibody-drug conjugate targeting Nectin-4, has been associated with side effects such as fatigue, peripheral neuropathy, rash, and hyperglycemia. Immune checkpoint inhibitors like pembrolizumab, used in the treatment of bladder cancer, commonly cause side effects including fatigue, rash, pruritus, diarrhea, and immune-related adverse events such as pneumonitis, colitis, hepatitis, endocrinopathies, and nephritis. These treatments aim to manage advanced urothelial carcinoma but come with a range of potential side effects that should be monitored closely.

What prior FDA approvals exist?

Enfortumab Vedotin is an antibody-drug conjugate targeting Nectin-4, and it has been approved by the FDA for the treatment of advanced urothelial carcinoma, particularly in patients who have previously received platinum-containing chemotherapy and a PD-1 or PD-L1 inhibitor. Other FDA-approved treatments for bladder cancer include immune checkpoint inhibitors such as Pembrolizumab and Atezolizumab, which target PD-1 and PD-L1, respectively. These treatments have shown efficacy in patients with advanced or metastatic urothelial carcinoma, providing additional options for those who have progressed on or are ineligible for traditional chemotherapy.

What other types of research exist?

Promising alternatives to Enfortumab Vedotin for bladder cancer patients include immune checkpoint inhibitors such as pembrolizumab and nivolumab. Combination therapies involving these agents, like nivolumab plus ipilimumab, are also potential options. Experimental therapies, including chimeric antigen receptor (CAR)-T cell therapies, are being tested and may offer new avenues for treatment.

Summary

This trial is testing a new drug called enfortumab vedotin alone and with other treatments in patients with advanced or muscle-invasive bladder cancer. The goal is to see how well these treatments work and what side effects they might have. Enfortumab vedotin targets and kills cancer cells, while pembrolizumab helps the immune system fight the cancer.

Who is the study for?

This trial is for adults with advanced or muscle-invasive urothelial cancer, including bladder and other urinary cancers. Participants should be eligible for certain chemotherapy drugs like cisplatin or carboplatin, and some may also qualify for pembrolizumab treatment. They must not have received specific prior treatments, have a good performance status (able to carry out daily activities), and an expected lifespan of at least 3 months.

What is being tested?

The study tests enfortumab vedotin alone or combined with anticancer therapies such as pembrolizumab, cisplatin, carboplatin, and gemcitabine. It aims to see if these treatments can shrink the cancer in patients with locally advanced or metastatic urothelial cancer as well as those with muscle-invasive bladder cancer.

What are the potential side effects?

Possible side effects include reactions related to the immune system affecting organs, infusion-related reactions from the drug entering the body, fatigue, digestive issues like nausea or diarrhea, blood disorders that affect cell counts and increase infection risk.

Other Research

Bladder cancer treatments often include chemotherapy, immunotherapy, and targeted therapies. Enfortumab Vedotin, an antibody-drug conjugate targeting Nectin-4, works by delivering a cytotoxic agent directly to cancer cells expressing Nectin-4, thereby minimizing damage to healthy cells. Immunotherapies like pembrolizumab and atezolizumab inhibit PD-1/PD-L1 pathways, enhancing the immune system's ability to attack cancer cells. These treatments are crucial for bladder cancer patients as they offer targeted approaches that can improve efficacy and reduce side effects compared to traditional chemotherapy, potentially leading to better outcomes and quality of life.
