If
you are a cancer patient or someone you know is a cancer patient,
you may be interested in learning more about clinical trials. The
information below offers a brief overview of the clinical trial
process, with a look at key questions and terms.
What are Clinical Trials?
Clinical trials, or research studies, utilize patient volunteers
to help investigate different ways to treat diseases - such as cancer.
Clinical trials involve the use of investigational drugs (also known
as study drugs) and drug delivery methods. Each study tries to answer
specific scientific questions about different ways to prevent, diagnose,
and treat whatever disease it is addressing.
Why are Clinical Trials Important?
Clinical trials contribute to the overall knowledge and progress
made in developing therapies for diseases, such as cancer. These
research studies are conducted to determine if a study drug or delivery
method is safe and effective. Patients who agree to participate
may possibly benefit from the research study, while receiving the
best current standard treatment as well.
How are Clinical Trials Structured?
Clinical trials are structured into four phases:
In
Phase I clinical trials,
researchers test a study drug in a small
group of people (20 to 80) for the first time to evaluate its
safety, determine a safe dosage range, and identify side effects.
In Phase II clinical trials,
the study drug is tested in a larger group of people (100 to 300)
to measure its effectiveness and further evaluate its safety.
In Phase III clinical trials,
the study drug is tested in large groups of people (1,000 to 3,000)
to confirm its effectiveness, monitor side effects, compare it
to approved standard treatments, and collect information that
will allow the study drug to be used safely.
In Phase IV clinical trials,
the drug is tested after it has been marketed to collect information
about its effect in various populations and about any side effects
associated with long-term use.
What
Happens During a Clinical Trial?
In many trials, if the patient is eligible and agrees to participate
through Informed Consent, the patient is randomized (by chance,
like a coin toss) to either receive the current standard treatment,
or the current standard treatment and the study drug regimen. If
no standard treatment is available, a trial may compare the study
drug to a placebo, which is similar to the study drug, but contains
no active ingredient. During a trial, patients are treated and monitored
by a team of health care professionals. This team will give the
patient specific instructions about the trial, about more tests,
and additional doctor's visits that might be required.
Throughout
the clinical trial, you come first. If there is no improvement or
you experience intolerable side effects, you and your physician
can decide to discontinue trial participation and resume other treatment
options. Should you do so, your decision will be respected without
any effect on future treatment plans.
Why
Do Some Cancer Patients Choose to Participate in Clinical Trials?
Some
cancer patients may participate because they are hoping for a possible
cure and longer life or a way to feel better. Others find that the
current standard therapies are not optimal for their cancer and
wish to be among the first to participate in a research study and
receive an investigational drug. Whatever the reason, participation
could make a difference in a patient's future, as well as in the
lives of future cancer patients.
How
Do I Know If I Should Participate in a Clinical Trial?
The
decision to participate in a clinical trial is one that only you
can make, with the help of your physician and the people close to
you. If you are interested in participating in a clinical trial,
you will be informed of the clinical trial's potential benefits
and drawbacks before making your decision. If the investigational
drug is proven to be effective, you may be among the first to benefit.
In addition, through your participation in a research study, you
will also be helping future cancer patients.
Are
There Risks Involved in Participating?
Because
clinical trials are research studies, study drugs may not be better
than current standard drugs or treatments. In addition, you may
experience side effects that are worse than those of current standard
drugs and treatments. Also, your health insurance company or managed
care provider may not cover all of the patient care associated with
a clinical trial. All of these factors should be discussed thoroughly
with your physician and those close to you before deciding whether
or not to participate in a clinical trial.
Where
are the Trials Held?
Many clinical trials may be available right in your own community.
Ask your physician for specific information or search the Suburban
Hematology-Oncology clinical trial list or
http://www.cancer.gov/clinicaltrials/ to find a current trial
in your region.
How
Do I Learn More About a Specific Clinical Trial?
Through a process called "Informed Consent," you will
learn the key facts about a particular clinical trial before making
a decision about participating. Your doctor will explain the purpose
and requirements of the study, including any potential drawbacks
and benefits. If you agree to take part in the trial, you will be
asked to review and sign a form that outlines the study's details
prior to participating.
How
Do I Get More Information?
Consult your physician to find out whether or not there is a clinical
trial that would be appropriate for your care. You can also contact
our clinical research coordinator, Kathy Frank, at 678-533-1567
or via e-mail at [email protected].
