What is
a clinical trial?
The purpose of
trials is to gain knowledge about new treatments that might benefit
future patients. But in the trial, the new treatment is still under
investigation to see how well it works. Although “new” often
implies “better” in our culture, the fact is that until clinical
research on a new treatment is complete, we do not know if it is
better, the same as, or worse than standard treatments. The only
way to find out is through well-designed and well-conducted clinical
trials.

Is
participating in a trial different from receiving treatment outside
of a clinical trial?
Yes. From a patient perspective, it
is important to understand that the main purpose of treatment in a
clinical trial is different from the purpose of treatment outside a
clinical trial. Treatment in a clinical trial is intended to
benefit society and future patients by advancing medical knowledge.
It is important to understand that individual patients may or may
not benefit from the experimental treatment in a trial; this is why
the trial is being conducted – to find out how well it works. However, patients may experience
other types of immediate benefits, such as the comfort and support
that can come from being part of a group of patients with the same
condition being treated and closely monitored by a team of experts.
For
patients in trials, there are risks associated with
participating because researchers cannot guarantee that a
treatment being tested will provide a benefit. In a trial,
there is only the hope that it will. The very reason for doing
the trial is to find out if the treatment works. Weighing the
risks and benefits to make an informed decision about whether to
participate can be complicated. In making an informed decision,
it is necessary to understand something about the different
types of trials, the right questions to ask, and patients’
rights as trial participants.

What
are the different types of clinical trials, and what do I need to
know about them?
There are four general phases of
trials in humans (phases one through four). Human trials cannot
begin until laboratory and/or animal tests on the new treatment
under investigation have been completed in “preclinical studies.”
The results of each phase must show that there are no serious safety
problems and that the experimental treatment holds some promise
before it can be tested in the next phase.
The risks involved and impact of one
trial on quality of life could be very different.” The different
phases of the trials are as follows:
* Note: NMMC engages in Phase two,
three, and four trials
·
Phase one trials assess safety and toxicity of the treatment
in a small group of healthy volunteers or patients with the disease
of interest. Phase I trials are not designed or intended to be
therapeutic. These trials cannot promise individual patients any
therapeutic benefit because very little is known at this point about
the treatment’s activity in humans. Phase I trials lay the
groundwork for the next phases of trials that begin to test efficacy
(how well the treatment works).
·
Phase two trials further test safety
and begin to test efficacy, typically in 50 to 300 patients with the
condition or disease for which the treatment is intended. Phase II
trials may take up to two years.
·
Phase three trials study safety and efficacy in a larger
group, perhaps thousands of patients, and look for uncommon adverse
reactions. This phase may last several years. Phase III trials
typically compare the new treatment to standard treatment(s) and
perhaps a placebo, if it is ethical to use one (trials for
life-threatening diseases rarely use placebos). Trials that compare
treatments are controlled trials and may involve random assignment
of patients to different treatment groups.
·
Phase four trials
are sometimes done after a new drug or device has received U.S. Food
and Drug Administration (FDA) approval and is being used by the
general public. Phase IV trials determine longer-term effectiveness
and identifies rarer side effects. FDA does not require this phase
of trial for all newly approved drugs or devices – it depends on
whether FDA believes some questions still need to be answered.
Patient safety, the protection of patients’ rights in clinical
trials, and the impact of trial participation on a patient’s
quality of life are the main reasons it is worth taking the time
to understand something about the different kinds of clinical
trials. Different kinds of trials offer different potential
benefits and risks; they also require different levels of
participation by patients. For example, a trial that is done on
an outpatient basis may have a very different impact on a
patient’s lifestyle than a trial that requires hospitalization.
Some trials may require follow-up tests that are time-consuming
and/or invasive, such as a biopsy, and others may just require
an office visit and quick exam. Some trials may last less than
a year; others may last five years or longer. Factors like
these may affect a person’s desire and ability to participate.

How will I learn about the risks and
benefits of participating in a trial?
An eligible patient cannot enroll in a trial until the known
benefits, risks, purpose, and plan for the trial have been
thoroughly explained and all the patient’s questions have been
answered. This is called the consent process. It is also often
called informed consent. It is very important to take the time to
read and consider all the information provided and to ask
questions. That often means taking the consent form home to read it
again and discussing it with close family, friends, and advisors.
Also, taking a trusted family member or friend along to the consent
interview may be helpful so someone else hears the same information
and you can discuss it later. If a patient decides to enroll in a
trial after the interview, he or she signs a consent form and keeps
a copy for future reference. This document contains everything that
was explained orally, including the contact information for someone
on the research team who can answer questions and respond to
emergencies.
Even after a patient enrolls in
a trial, he or she can withdraw at any time for any reason.
Should you choose to withdraw, it is very important to let the
researchers know why you are withdrawing so they can collect
important data that may affect the way they are conducting the
trial. Patient consent is an ongoing process throughout the
trial. If important new information is gained about the
experimental treatment during the trial, researchers are
required to share it with patients and reconfirm their consent
to participate.
The following information may
help you determine whether you have received all the information
you need for your decision making before signing a consent form:
· Explanation
that the trial involves research
· Summary
of results from previous trials that led to this trial
· Purpose
of the new research and what it is trying to achieve
· Duration
of the trial for the patient if he or she remains in it until
the end
· Detailed
description of each test and treatment that will be given
according to the trial protocol
· Timing
and location of those tests and treatments and how they are
scheduled for the patient
· Identification
of any procedures that are experimental
· Description
of any foreseeable risks or discomforts from any test or
treatment given
· Description
of any possible benefits to participants or others
· Description
of treatment alternatives that might help participants
· Statement
about the extent to which confidentiality of participants’
records will be maintained
· Explanation
of whether any compensation and/or medical treatments are
available if injury occurs from treatment in the trial. If so,
what are they and who will provide them?
· Whom
to contact with questions about the trial and the participant’s
rights
· Whom
to contact in the event of a research-related injury
· Statement
that participation is voluntary and that participants may refuse
or discontinue participation at any time without penalty
· Itemization
of direct costs to the patient as a result of participation

Will I be eligible for the
trial I want to enroll in?
When you find out about a trial
that you might be interested in, you will need to contact the
researchers to find out if you are eligible. Every trial has
eligibility criteria (also called inclusion and exclusion
criteria). These criteria state what patient characteristics
make the patient eligible or ineligible for the trial, such as
age, health, disease stage, previous treatment, and other
coexisting health conditions. Even when people have the same
disease, there can be important differences among patients. For
example, patients may be in different stages of the disease,
which might mean that they should get different treatment. Or,
patients may have other health conditions that exclude them from
the trial. So, there are several reasons for eligibility
criteria. First, patient safety is a major concern. Second,
the researchers have an objective. They are trying to gather
data in the trial to answer some very specific questions. They
need to be able to account for factors that can affect patient
treatment and outcome. Some patient characteristics can get in
the way of being able to tell if the treatment works or not;
those characteristics may be excluded so that researchers will
be able to answer the questions they set out to answer.

Who ensures patient safety and
the qualifications of the researchers and research organization
involved in the trial?
Several federal agencies have
different roles for protecting patient safety and rights in
clinical trials. Food and Drug Administration (FDA) has
oversight of trials that are testing new drugs and medical
devices before they are brought to market. National Institutes
of Health (NIH) oversees trials that it funds at institutions
throughout the country. Office for Human Research Protections (OHRP)
works with FDA, NIH, and other federal agencies to provide
training to researchers and to help ensure patient protections
according to federal regulations. The local Institutional
Review Board (IRB) reviews the trial protocol for every trial
conducted in its institution and/or affiliated facilities.

Do all the patients in a trial
receive the same treatment?
It depends on the type of
trial. For trials that have more than one treatment group,
scientific processes may be used to assign patients randomly to
treatment groups. The purpose of randomization is to evenly
distribute patient characteristics in each group in a trial to
ensure valid results. It is also done to prevent researchers
from influencing (consciously or unconsciously) to which group
patients are assigned. Some patients have said that they do not
want to enroll in a trial because they might be randomly
assigned to a treatment group. They have expressed feelings
that it takes away some control and choice about treatment.
They also fear being assigned to the control group, which is the
group that receives some other treatment and not the
experimental treatment. Some patients believe the experimental
treatment is better because it is new. Others fear being
assigned to a group that receives placebo (inactive treatment).
The following are some key points to keep in mind:
·
For patients with a
life-threatening disease, the control groups virtually always
consist of other treatments that have some proven efficacy.
Placebos are very rarely used. Remember, the main point of the
trial is to determine how well the experimental treatment works
because no one knows yet if it is better than, the same as, or worse
than standard treatment. A control group is a group that receives
some other treatment of known efficacy in the trial. Results from
the experimental treatment group are compared to results from the
control group to see how well it works. Placebo is an inactive
treatment usually designed to look exactly like the real treatment.
It is often thought of as a pill, but can also be an injection, a
physical manipulation, a device that is inactive, or any other
appropriate procedure that simulates the experimental treatment.
There are stringent federal and ethical guidelines about when a
placebo can be used. It can only be used when there is no risk of
harm to the patient who receives placebo instead of the experimental
or standard treatment.
· A
treatment that is new and experimental is not necessarily better.
The experimental treatment may be the same as, better, or even worse
than the standard treatment. Keep in mind that control groups often
receive the current gold standard in treatment. The risks may be
greater in the experimental treatment group because less is known
about the treatment. Also, patients in the control group receive
the same close monitoring and evaluation as those in the
experimental group. So, no matter which group a patient is in, he
or she will receive excellent care for the condition being treated
by a team of researchers.
· Several
studies have shown that patients participating in trials survive
longer than similar patients who were eligible for a trial but chose
to receive treatment outside a trial. The reasons for this are not
clear, but some believe that this is because, typically, patients in
a trial receive closer medical attention and more follow-up visits
to monitor their condition than patients who are not in a trial.

Will I incur any costs by
participating in a clinical trial?
There are tangible and
intangible costs that patients may want to consider. Tangible
direct costs may vary depending on the type of trial you have
entered. Decisions about charging trial participants for
experimental drugs and devices that are not yet FDA approved are
guided by professional ethics, institutional policies, and FDA
regulations. In drug trials, there is rarely a cost to the
patient for the experimental drug – the sponsor absorbs the cost
of this as part of its research and development cost unless FDA
has given the company special approval to charge for the drug.
For trials that involve a device, there often is a cost for the
device. Whatever the direct costs of care, any patient
enrolling in a trial must be informed of those costs.
Regulations require that the consent form outline all costs for
care that will be billed to patients or their insurance
companies as a result of participation in the trial. FDA does
not prohibit charging participants for treatment or services in
a trial. The IRB overseeing the trial has the responsibility to
ensure that any such charges are appropriate and fair.
Some costs for clinical trial
participation may also be “indirect,” but very important to
consider. These would include the costs for travel, lodging, and
additional lost time from work when participating in a trial. The
clinical trial research coordinator or a patient advocate from the
trial may be able to help you figure out what those costs would
amount to over the full course of the trial. You should also ask
who is responsible for paying the costs of treatment for any
complications or side effects caused by trial participation, should
they occur. Intangible costs of the trial include
separation from loved ones during the trial and other
quality-of-life issues affecting a patient’s daily life activities.
For example, side effects from treatment, even if they are deemed
“minor” and “temporary,” such as nausea, can significantly affect a
patient’s activities and feelings. So, it is important to consider
the potential impact of the trial on your activities, quality of
life, and relationships with loved ones.

Will my health insurance pay?
Many health insurers and Medicare now
pay for costs of routine care given in the context of a clinical
trial. Routine care costs typically include the medical care a
patient would need whether or not he or she was in a trial.
Examples of a routine cost might be the tests that are needed for
diagnosis and staging of the disease or some of the patient checkups
needed to monitor disease status. Patients will need to check with
their insurers about what costs of trials are covered. Some states
have mandated health insurers to cover some of the costs of
participation in trials.

Should I be concerned about
the privacy of my personal health information when participating in a
clinical trial?
North Mississippi Health Services is in compliance with HIPAA (Health
Insurance Portability and Accountability Act) which ensures the privacy of
medical information. The HIPAA regulations also protect personal health
information that is used in clinical trials. The NMHS IRB oversees the
privacy requirements of all clinical trials and ensures compliance with all
state and federal regulations that protect your personal health information.
