FAQs About Cancer Clinical Trials

Clinical trials for cancer are essential to the advancement of medical treatments, but they also provide people with opportunities for targeted care and access to novel therapies.

Clinical trials for cancer are how researchers test the safety and effectiveness of new therapies.

There are many reasons to consider participating in a clinical trial. In addition to helping improve cancer treatment for the future, participating in a clinical trial lets you work closely with a research team specializing in your diagnosis. You’ll receive targeted, individual care, and many clinical trials may cover related medical costs.

If cancer is not responding to traditional therapies or is in an advanced stage, clinical trials can offer a way to try emerging treatments that are not yet available to the public.

Knowing if a clinical trial is right for you starts with a conversation at your doctor’s office. Talking about clinical trials with your doctor can help you understand what they might mean for your care and help you make informed decisions about your treatment plan.

Preparing before the conversation with your doctor can help ensure the discussion is informative, productive, and addresses all your questions and concerns.

Tips to prepare include:

• Research clinical trials and learn the basics.
• Search for trials that might be relevant to your condition.
• Bring a list of trials you’re interested in.
• Answer honestly about why you want to consider a clinical trial.
• Write down your questions and concerns so none get forgotten.
• Bring a notepad to write down your doctor’s responses.
• Consider bringing a friend for support and to help retain information.

Your questions about clinical trials for cancer will drive the conversation with your doctor. Here are some important ones to consider:

Understanding the type and stage of your cancer is the first step in screening for clinical trial eligibility.

Knowing your treatment options helps you determine if a clinical trial is the best option compared to standard therapies.

Some cancer diagnoses, particularly those with effective, established treatments, may not have as many available clinical trials as hard-to-treat cancers.

Each clinical trial is conducted for a set period of time, depending on its research phase and goals.

Clinical trials may require multiple treatments or extensive testing to monitor the effects and safety parameters of the therapy being evaluated.

Clinical trial treatments may focus on improving specific signs or symptoms in a cancer diagnosis. Not all clinical trials report results back to the volunteer.

Placebos are rarely used in clinical trials for cancer. But if they are, there is a chance you may be placed in the placebo group rather than the therapy group.

There are different types of clinical trials and different phases of research within those trials. Having a basic understanding of how they work can help you know what to expect during the experience.

Types of clinical trials include:

• Treatment trials: evaluate new and emerging therapies for cancer
• Prevention trials: look at ways to prevent cancer among people at risk
• Screening trials: explore ways to test for cancer earlier
• Supportive/palliative care trials: work to improve the quality of life with cancer

Clinical trials for cancer are available in four phases:

• Phase 1: A small group of volunteers provides preliminary data on a treatment’s safety, side effects, and highest tolerated dose.
• Phase 2: The new therapy is tested against cancer to determine its safety, effectiveness, and short-term side effects.
• Phase 3: The new therapy is compared against a standard therapy to see which one is more effective and if the therapy can be approved for public use.
• Phase 4: The long-term safety and effectiveness of a therapy are tested after it has been made available to the public.

Research shows that people focus on four main information needs when considering clinical trials:

Knowing the basics about a trial helps you know what to expect. Foundational information to discuss with your doctor includes:

• the goal or purpose of the trial
• who the trial is for (the eligibility)
• the trial’s phase
• the type of treatment being evaluated
• participation schedule
• benefits and risks
• duration
• costs and insurance coverage

Conflicts of interest happen when someone involved in a clinical trial has a personal or financial interest that might bias how they conduct the study or treat volunteers.

While conflicts of interest aren’t always obvious to a trial participant, you can find out about a trial’s financial and organizational structure by thoroughly reading your informed consent form.

The informed consent form is a document required by the federal government for research participants. It must be reviewed and signed when you agree to a clinical trial. Your doctor can read through it with you to search for areas of concern.

Clinical trials are investigative. There’s no guarantee a clinical trial will improve your cancer diagnosis, and it may require you to change your current course of treatment.

Ask your doctor how a clinical trial will affect your current treatment plan before, during, and after participation.

An effective relationship with your doctor is based on trust and open communication. Having a focused conversation about your treatment options, including clinical trials, can be an important step in your cancer treatment plan.

If your doctor has not brought up a clinical trial yet, you can consider starting the conversation.

There are many reasons to consider participating in a clinical trial for cancer, but clinical trials may not be a good fit for everyone or every cancer diagnosis.

Talking about clinical trial options with your doctor can help you make an informed decision about their potential impact on your cancer treatment plan. Coming to your appointment prepared with questions is one easy way to keep the conversation informative and productive.
