Trial Summary

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

The trial protocol does not specify if you need to stop your current medications. However, you cannot participate if you are on chronic systemic steroid therapy exceeding 10 mg daily of prednisone equivalent or any other form of immunosuppressive therapy within 7 days prior to the first dose of the study drug. It's best to discuss your current medications with the trial team.

What data supports the idea that Pembrolizumab for Bladder Cancer is an effective drug?

The available research shows that Pembrolizumab is effective for treating bladder cancer in several ways. It was approved by the FDA for patients with a specific type of bladder cancer that doesn't respond to other treatments and who can't or don't want to have surgery. In studies, Pembrolizumab was used before surgery for muscle-invasive bladder cancer and showed positive results. It was also compared to traditional chemotherapy for advanced bladder cancer and was found to help patients live longer. This makes it a strong option for those who can't use standard chemotherapy.12345

What data supports the effectiveness of the drug pembrolizumab for bladder cancer?

Pembrolizumab has been approved by the FDA for certain types of bladder cancer, showing effectiveness in patients who cannot undergo surgery or have not responded to other treatments. It has also shown benefits in improving survival for advanced bladder cancer patients compared to traditional chemotherapy.12345

What safety data is available for pembrolizumab in bladder cancer treatment?

Pembrolizumab, also known as Keytruda or MK-3475, has been evaluated for safety in several studies. It is approved by the FDA for BCG-unresponsive, high-risk, non-muscle invasive bladder cancer. Safety concerns include immune-related adverse events, as reported in a case of pembrolizumab-induced myasthenia gravis with myositis and presumable myocarditis in a bladder cancer patient. The KEYNOTE-012 study assessed its safety in locally advanced or metastatic urothelial cancer, and a real-life study evaluated its safety in metastatic urothelial carcinoma patients. Overall, pembrolizumab has shown clinical benefits but also potential safety risks that need to be monitored.26789

Is pembrolizumab safe for humans?

Pembrolizumab, also known as Keytruda, has been studied for safety in various conditions, including bladder cancer. Some patients have experienced immune-related side effects, such as myasthenia gravis (a condition causing muscle weakness) and myocarditis (inflammation of the heart). However, it has been approved by the FDA for certain types of bladder cancer, indicating that its benefits may outweigh the risks for some patients.26789

Is the drug Pembrolizumab a promising treatment for bladder cancer?

Yes, Pembrolizumab is a promising drug for bladder cancer. It has been approved by the FDA for certain types of bladder cancer that don't respond to other treatments. It has shown to improve survival in advanced bladder cancer and is effective for patients who can't use other common treatments.2381011

What makes the drug pembrolizumab unique for treating bladder cancer?

Pembrolizumab is unique because it is an immune checkpoint inhibitor that targets PD-1, helping the immune system attack cancer cells. It is approved for patients with bladder cancer who cannot undergo surgery or have not responded to other treatments, offering a new option for those with limited choices.2381011

What is the purpose of this trial?

Subjects with cT2-T3N0M0 urothelial cancer of the bladder will be enrolled. After completing two cycles of pembrolizumab, subjects will undergo a restaging MRI of the abdomen and pelvis with a standard acquisition protocol (as outlined in the protocol) as well as CT chest. A CT of the abdomen and pelvis may be performed if there are contraindications to MRI. Patients will also undergo a restaging cystoscopy and biopsies/TURBT as outlined in the protocol.Patients achieving a clinical complete response to treatment (defined in the protocol) will proceed with "maintenance" single agent pembrolizumab followed by surveillance. All other patients will proceed with standard of care local therapy as per their treating physicians followed by "adjuvant" pembrolizumab.

Treatment Details

Interventions

  • Pembrolizumab
Trial Overview The trial is testing Pembrolizumab in patients after they've undergone tumor removal surgery. Patients will receive two cycles of Pembrolizumab followed by MRI/CT scans and cystoscopy to check response. Those responding well continue on Pembrolizumab; others follow standard care then get 'adjuvant' Pembrolizumab.

Group I: Experimental GroupExperimental Treatment1 Intervention
Cycles 1-2 (Pembrolizumab): 400 mg of Pembrolizumab intravenously (Administered Day 1 of 42 day Cycle) If complete response of treatment is observed then maintenance therapy will be given. All other patients will receive with standard of care local therapy (cystectomy or chemo-radiation) as per their treating physicians followed by "adjuvant" pembrolizumab.

Findings from Research

In a study of 39 patients with muscle-invasive bladder cancer, the combination of gemcitabine, cisplatin, and the immune checkpoint inhibitor pembrolizumab was effective, achieving pathologic downstaging in 56% of patients and complete pathologic response in 36%.
The treatment was generally safe, with common side effects including thrombocytopenia, anemia, and neutropenia, but no severe immune-related adverse events were reported, indicating a manageable safety profile for this neoadjuvant therapy.

Pembrolizumab (Keytruda) has been approved by the FDA for treating high-risk, non-muscle invasive bladder cancer (NMIBC) in patients who are unresponsive to BCG therapy and are either ineligible for or have opted not to undergo cystectomy.
This approval specifically targets patients with carcinoma in situ (CIS) with or without papillary tumors, highlighting its role as a treatment option for those with limited surgical options.
FDA Approves Pembrolizumab for BCG-Unresponsive NMIBC.Wright, KM.[2021]
In the Phase III KEYNOTE-045 trial, pembrolizumab significantly improved overall survival in patients with second-line metastatic urothelial carcinoma compared to standard treatments like docetaxel, paclitaxel, and vinflunine.
Early results from the Phase II KEYNOTE-052 trial suggest that pembrolizumab is effective for first-line treatment in patients with metastatic urothelial carcinoma who are not eligible for cisplatin, leading to its FDA approval for these indications.
