Trial Summary

What is the purpose of this trial?

This trial is testing enfortumab vedotin, a drug that targets and kills cancer cells, in patients with upper urinary tract urothelial carcinoma who can't or won't use cisplatin and are planning surgery. Enfortumab vedotin is a new type of drug that targets a specific protein on cancer cells and delivers a substance that kills these cells.

Do I need to stop my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you are on therapeutic anticoagulation (blood thinners), you must be on a stable dose. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the drug Enfortumab Vedotin for bladder cancer?

Enfortumab Vedotin has been shown to be effective in treating advanced bladder cancer, with a study reporting a 44% response rate in patients who had previously received other treatments. This drug works by targeting a protein on cancer cells and delivering a toxin to kill them, offering a new option for patients with limited treatment choices. ^{1 2 3 4 5}

Is Enfortumab Vedotin safe for humans?

Enfortumab Vedotin, also known as Padcev, has been associated with some serious side effects, including high blood sugar, nerve damage, eye problems, skin reactions, and risks to unborn babies. In studies, 73% of patients experienced severe side effects, and up to 47% had skin reactions. ^{1 2 3 4 6}

What makes the drug Enfortumab Vedotin unique for bladder cancer treatment?

Enfortumab Vedotin is unique because it is the first drug specifically approved for patients with advanced bladder cancer who have already been treated with PD-1/PD-L1 inhibitors and platinum-based chemotherapy. It works as an antibody-drug conjugate targeting Nectin-4, a protein found on cancer cells, and is administered intravenously. ^{1 2 3 5 6}

Eligibility Criteria

This trial is for adults with high-grade urothelial carcinoma of the upper urinary tract who can't or choose not to take cisplatin and are planning on having surgery. They should have adequate kidney function, hearing loss no worse than Grade 2, a good performance status, stable blood counts and liver enzymes, and not be pregnant or breastfeeding. People with uncontrolled diabetes, recent major surgery, active heart disease or infections like tuberculosis or hepatitis B/C cannot join.

Inclusion Criteria

My blood counts and liver function tests are within the required ranges, and if I have HIV, it's under control.

I have a specific type of bladder cancer that has not spread beyond my pelvis.

Exclusion Criteria

My cancer has spread to other parts of my body.

I've had chemo or radiation for bladder cancer in the last 2 years.

I had a heart attack in the last 6 months.

Treatment Details

Interventions

• Enfortumab Vedotin
• Radical surgery

Trial Overview The study is testing Enfortumab Vedotin's effectiveness and safety in treating cancer before patients undergo standard radical surgery to remove their tumors. It targets those who aren't eligible for cisplatin chemotherapy.

Participant Groups

Group I: Enfortumab Vedotin Experimental Treatment 2 Interventions

All patients will receive enfortumab vedotin at 1.25 g/kg on days 1 and 8 of 21 days cycle, for a total of three cycles, followed by radical nephroureterectomy, ureterectomy, or nephrectomy, depending on the site of the tumor and per the clinical decision of the treating urologist.

Findings from Research

Enfortumab vedotin (Padcev) is the first FDA-approved treatment specifically for adults with locally advanced or metastatic urothelial cancer who have already undergone treatment with PD-1/PD-L1 inhibitors and platinum-based chemotherapy.

This approval marks a significant advancement in cancer therapy, providing a new option for patients who have limited treatment choices after previous therapies.

Enfortumab vedotin-ejfv (EV) is an effective treatment for locally advanced or metastatic urothelial carcinoma (UC), showing a 44% overall response rate and a median overall survival of 11.7 months in heavily pretreated patients.

While EV demonstrates significant antitumor activity, it also presents unique toxicity concerns that require careful monitoring, highlighting the need for further studies to optimize its use in clinical practice.

Enfortumab vedotin (PADCEV) received accelerated FDA approval for treating locally advanced or metastatic urothelial cancer in patients who have already undergone specific prior therapies, based on substantial evidence from a study involving 125 patients.

The treatment showed a confirmed objective response rate of 44%, with a median response duration of 7.6 months, although 73% of patients experienced grade 3-4 adverse reactions, highlighting the need for careful monitoring of side effects.

Enfortumab vedotin-ejfv is a first-in-class monoclonal antibody drug conjugate that effectively targets Nectin-4 on bladder cancer cells, delivering a toxin that induces cell death, leading to improved overall survival in patients with metastatic urothelial carcinoma who have limited treatment options.

The drug has demonstrated a high response and disease-control rate with an acceptable toxicity profile, making it a significant advancement in the standard of care for this aggressive cancer.

Enfortumab vedotin-ejfv (EV) is an effective treatment option for adults with locally advanced or metastatic urothelial carcinoma who have already received PD-1/PD-L1 inhibitors and platinum-based chemotherapy, as it targets the Nectin-4 protein.

To maximize the benefits of EV therapy, it is crucial to educate patients and caregivers, monitor for adverse events, and intervene promptly to manage any side effects that may arise during treatment.

Enfortumab vedotin, a treatment for advanced bladder cancer, can cause severe skin reactions, with a case report highlighting a patient who developed toxic epidermal necrolysis shortly after starting the drug.

The case emphasizes the need for careful monitoring of skin reactions and suggests that if such reactions occur, treatment may need to be reduced or stopped to prevent serious complications.
