Understanding Clinical Trials

Are clinical trials right for you or a loved one? Choosing a treatment, or choosing no treatment after a prostate cancer diagnosis or recurrence can be a overwhelming and scary experience, whether you are the one diagnosed or a loved one along for the ride. There’s radiation therapy, prostatectomy, active surveillance, hormone therapy each with their advantages and challenges. These decisions require in-depth conversations with healthcare providers, research, and often involve discussions with family and loved ones. Yet there’s another option, which isn’t often top of mind for patients and families during this time, clinical trials. Learn more about clinical trials and explore another option in your prostate cancer journey.

What Are Clinical Trials?

Clinical trials are research studies that help doctors find new safe and effective medicines, therapies, and devices to prevent, diagnose, and treat diseases. They also help determine whether the treatment’s risks are worth the benefits. In the field of prostate cancer there are hundreds of trials currently recruiting patients. It is worth exploring whether there is one that’s right for you or your loved one.

Different Types of Clinical Trials
There are 4 different kinds of clinical trials:

  • Treatment trials test new drugs, surgeries, therapies or a combination of these.
  • Prevention trials test new medicines, vitamins, or changes in lifestyle to find the best ways to prevent disease.
  • Screening trials find the best way to identify diseases, especially in their early stages.
  • Quality of Life trials try to explore ways to improve comfort and quality of life for patients. In prostate cancer this may include ways to reduce pain associated with bone metastases or improve side effects like incontinence or erectile dysfunction.

Phases of Clinical Trials
Most clinical trials will pass through several phases to examine the safety and effectiveness of a drug while protecting patients. Generally, clinical trials fall into one of the following phases:

  • Phase I: These studies test a new drug or treatment in people for the first time to evaluate safety, dosage amounts, and side effects.
  • Phase II: A phase II trial continues safety testing and begins to evaluate how well the drug or treatment works in a larger group of people.
  • Phase III: In phase III the new drug, treatment, or surgical procedure is compared to the current standard treatment. These studies typically enroll large numbers of people at multiple locations across the country. These trials confirm effectiveness, monitor side effects, and accumulate data that allows the drug to be used safely.
  • Phase IV: Phase IV rials take place after a treatment has been approved by the Food and Drug Administration (FDA) and marketed to consumers. These studies continue to gather information on the treatment’s side effects, benefits and risks to ensure that it is safe and effective.

How Many People Participate in Clinical Trials?

According to the National Cancer Institute, less than 5% of cancer patients participate in clinical trials. It is estimated that if just 10% participated, most studies would take only one year to complete compared to the current timeline of three to five years. This could mean innovative treatments reaching patients quicker.

What are the benefits?

There are a number of possible benefits to participating in a clinical trial:

  • Participants may get new treatments before they are widely available.
  • The costs directly related to the clinical trial, including treatments, tests and doctor visits are provided at no cost to the patient. This provision was included in the Patient Protection and Affordable Care Act of 2010.
  • If a patient has unsuccessfully tried other available treatment options, a clinical trial may provide patients and families a renewed hope for successful treatment.
  • Participants will receive care from some of the leading physicians and health care facilities in the country.
  • Clinical trials give doctors and researchers information to develop new treatment options and possibly save lives. Many of today’s most effective treatments have been made available thanks to previous clinical trial results. With a disease like prostate cancer that kills over 32,000 men every year these new options are desperately needed.
  • Patients can play a more active role in their own health care.

 

What are the risks?

When a new treatment is being studied doctors and researchers don’t know all of the risks and side effects that may be involved. Below are a few possible risks that should be considered:

  • The new treatment may not work as well as the standard treatment or it may not work at all.
  • The new treatment may have unpleasant or life-threatening side effects.
  • You may have to make more trips to the doctor and undergo more testing compared to the standard treatment.

 

Why Do So Few Cancer Patients Participate in Clinical Trials?

Each patient may have a different reason for choosing whether or not to participate, but some common reasons are:

  • Patients just don’t know about clinical trials. And with the number of trials that are going on at any one time, it’s not always easy for patients or doctors to keep track of trials that might be an appropriate fit.
  • Some patients may be afraid or suspicious of participating in research or feeling like part of an experiment. However, today’s clinical trials have strict guidelines and measures to ensure patient safety and equality.
  • Participating in a clinical trial may require a significant time commitment. Patients may need to make more trips to the doctor and undergo more testing compared to getting the standard treatment.

 

How do I know if a clinical trial is safe?

If you or a loved one are considering participating in a clinical trial you may have some concerns about whether they are safe and how they are monitored. However, the Federal Government has put in place several strict guidelines and measures to ensure that patient safety is put first.

First, clinical trials must follow a protocol, or plan for the study, created by the lead doctor or researcher for the trial. The protocol thoroughly explains what the trial will do, how the study will be conducted, and the importance of each part of the study. It makes certain that patients are treated exactly the same no matter where they are receiving treatment and that every doctor conducts the trial properly.

Additionally, each center that offers a clinical trial is monitored by an Institutional Review Board (IRB). An IRB must approve a clinical trial before it can begin, and members carefully watch the progress of the research throughout the study.

In some trials, often larger, multi-site trials, a Data Safety Monitoring Board (DSMB) may be used. The DSMB tracks data to ensure patient safety and make sure that results are being reported completely. If they find that a treatment is harmful to patients or if one treatment is significantly better than another they may stop a study altogether or switch patients to the more effective treatment.

Remember, every participant in a trial is carefully observed by doctors to determine how the treatment is working and to track any side effects.

 

How do I participate in a clinical trial?

Keep in mind that clinical trials may not be right for everyone. If you or a loved one are considering participating in a clinical trial it is important to educate yourself as much as possible about the potential benefits, risks, and outcomes of the trial.

You may find out about a clinical trial from your doctor or may learn about it on your own through a newspaper ad or a website. If you find a trial that you are interested, you will want to take the following steps:

  • Talk to your doctor. Your doctor may be familiar with the trial or therapy that the trial is studying. She may be able to tell you whether you would be eligible for the trial and discuss some of the benefits and risks.
  • Contact the trial coordinator. Each clinical trial has a coordinator and their contact information is usually listed in the trial announcement. Either you or your doctor can speak with the coordinator about whether you meet the criteria for the study and ask any remaining questions you may have.
  • Screening. You will schedule a time for a pre-trial screening in which you’ll undergo tests to make sure that you qualify for the study. You will also get a chance to speak further with investigators about the trial.
