What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests new combinations of three drugs—Durvalumab (an immunotherapy drug), Tremelimumab (an immunotherapy drug), and Enfortumab Vedotin (an antibody-drug conjugate)—to evaluate their effectiveness and safety in treating muscle-invasive bladder cancer, particularly for those unable or unwilling to use cisplatin-based chemotherapy. Participants will receive one of two new drug combinations before and after surgery or undergo surgery with or without standard cancer treatments. This trial is suitable for individuals who have not previously received chemotherapy or immunotherapy, have bladder cancer that has spread into muscle but not beyond nearby lymph nodes, and are medically prepared for surgery. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.

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

The trial protocol does not specify if you need to stop your current medications. However, you cannot use immunosuppressive medication within 14 days before the first dose of the investigational products.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot use immunosuppressive medication within 14 days before starting the trial treatment.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that the combination of Durvalumab and Tremelimumab is generally safe. In one group of patients, this combination was well-tolerated, though it showed limited effectiveness. Studies have demonstrated that Durvalumab and Enfortumab Vedotin are generally safe and effective, particularly for certain types of bladder cancer. Both treatment combinations have undergone testing in several trials and are usually well-tolerated, but they may have side effects. Discuss any concerns with a healthcare provider. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of Durvalumab, Tremelimumab, and Enfortumab Vedotin for bladder cancer because it offers a novel approach compared to standard treatments like chemotherapy and surgery. Durvalumab and Tremelimumab are types of immunotherapy drugs called checkpoint inhibitors, which help the immune system recognize and attack cancer cells more effectively. Enfortumab Vedotin is an antibody-drug conjugate that directly targets cancer cells, delivering a potent chemotherapy agent right where it's needed. This combination is particularly promising as it not only aims to enhance the body's immune response but also delivers targeted therapy to cancer cells, potentially improving outcomes for patients with bladder cancer.

What evidence suggests that this trial's treatments could be effective for bladder cancer?

Research has shown that using Durvalumab and Tremelimumab together in bladder cancer patients appears promising. This trial will test one arm with the combination of Durvalumab, Tremelimumab, and Enfortumab Vedotin. Previous studies found that up to 54% of patients experienced complete cancer remission when Durvalumab was combined with other treatments. Researchers are testing Tremelimumab with Durvalumab to enhance treatment effectiveness. Another arm in this trial will test Durvalumab with Enfortumab Vedotin, which has proven effective in treating advanced bladder cancer and extending patient survival. These findings suggest that combining these treatments could be a strong option for individuals with muscle-invasive bladder cancer who cannot undergo standard chemotherapy. ^{1 2 6 7 8}
