Joining A Clinical Trial For Bladder Cancer

Last updated and reviewed on May 23, 2026

Joining a clinical trial is a big decision, but it is one that many patients consider when looking for the best possible care. A clinical trial is a carefully controlled research study where doctors test new ways to prevent, find, or treat diseases like bladder cancer. In 2026, these trials are more advanced than ever, offering patients a chance to try treatments that are not yet available to the general public.=

Clinical trials can test different things, such as:  

• New medications or combinations of medications

• New surgery or radiation techniques

• How well current treatments work for different groups of patients

• Other approaches that may improve the quality of life

All patients who enroll in clinical trials are volunteers. All medications approved by the U.S. Food and Drug Administration (FDA) must go through clinical trials to measure how safe and effective they are.

Clinical trials happen in stages called phases, and each phase answers different questions. 

• Phase I trials are the first time a new treatment is tested in people. Their main goal is to find out how much of a treatment is safe to give and what side effects it might cause. Phase 1 trials test a drug's dosage and safety.

• Phase 2 trials extend the research to a larger population.

• Phase 3 trials are generally randomized studies in large populations based on the experience of the Phase 1 trial in refining doses.

• Phase 4 trials study the safety and benefit of an FDA-approved treatment after it is already available to patients.

Before you can join a clinical trial, you have to meet certain rules called eligibility criteria. The rules may be about age, cancer type and stage, treatment history, or general health. They ensure that participants are alike in specific ways and that the trial is as safe as possible for the participants. This means that not everyone will qualify for every trial.

What Are the Reasons to Join a Clinical Trial?

There are several strong reasons why someone with bladder cancer might choose to join a clinical trial. 

• The most personal reason is the chance to access a treatment that is not yet available to the public. Patients reported participating in clinical trials because their doctors informed and encouraged them, they had no other treatment options if they wanted to live longer, or they wanted to help future patients with cancer. For some patients, a clinical trial may offer access to a drug or combination of drugs that could not be obtained any other way.

• A second reason to consider joining a trial is the quality of care and monitoring that comes with it. Patients in clinical trials are often seen more frequently by their care team and receive more detailed testing and follow-up than patients receiving standard treatment alone. Clinical trials provide an essential link between scientific discovery and clinical practice. These trials are crucial to the translation of new knowledge into tangible benefits for patients, and the knowledge gained in a clinical trial can also inform and guide further research into the biology of the disease. Being in a trial means that your health is being watched very closely by a dedicated research team whose entire focus is on your well-being and the data your care provider.

• A third reason is cost. Many people do not realize that joining a clinical trial can reduce out-of-pocket costs for some treatments. There is no fee to enroll in a clinical trial. The study sponsor pays for research-related costs, including the study drug. But you may need to pay for other services, like transportation or childcare, due to extra appointments. While the trial drug itself is generally provided at no cost to you, it is important to check with your insurance provider and the research team about what other costs may or may not be covered. Some trials also provide help with transportation and other expenses.

• A fourth reason, one that many patients find deeply meaningful, is the opportunity to help other people with bladder cancer in the future. Clinical trials are very important. They help doctors learn about cancer and develop better treatments that can help you and other people in the future. Every treatment that doctors use today, including the immunotherapy drugs and targeted therapies that are giving bladder cancer patients more time and a better quality of life, became available because of patients who volunteered for clinical trials in the past. By joining a trial, you become part of that progress.

• Finally, it is worth knowing that participation in clinical trials is still much lower than it could be, which means that many promising treatments take longer to reach patients than they should. It has been repeatedly estimated that less than 5% of adult cancer patients enroll in cancer clinical trials, even though 70% of Americans are estimated to be inclined or very willing to participate in clinical trials. The gap between the number of people who are willing to join trials and those who actually do is largely explained by a lack of information. If you are curious about clinical trials, the best first step is a conversation with your oncologist. You can also search for trials at any time by visiting ClinicalTrials.gov, the official U.S. government database of all currently active research studies.
