Because the informed consent document often lacks crucial information, the savvy
patient will obtain a copy of the trial's protocol. The protocol is a lengthy
and highly technical document that contains every scientific detail of the
clinical trial.
The protocol contains sections explaining the full scientific rationale of the
study. Why do the investigators expect this compound to be active in cancer?
What is its chemical makeup? What does it do in the test tube? How did it
perform in animal studies? How did it perform in earlier phases of human
testing?
And it contains sections explaining the detailed conduct of the present study.
How many patients, and what kind of patients will be enrolled? What are the
detailed inclusion and exclusion criteria? What drugs will be administered, and
when? What tests will be administered, and when? How is the clinical staff
supposed to respond to certain side effects and other contingencies? What would
cause them to drop you from the study?
All of these questions--and many more--will be answered in the protocol for
those patients willing to slog through language intended not for patients but
for scientists and regulatory agencies.
Joyce R. Niblack speaks from experience:
Before anybody goes into a clinical trial, they should get and read a copy of
the protocol. If there's something they don't understand, they need to ask
questions. And if there's anything in there that's not acceptable to them, they
need to negotiate. For example, in the first clinical trial I participated in,
the protocol required a bone marrow biopsy once a month. Now these are not fun.
My doctor asked me, "Do you want these once a month?" and I said, "Hell no!" He
said, "Well, I think it's insane." So I refused to agree to that. I negotiated
through my doctor. He felt it was absolute nonsense to require it once a month.
Interferon works slowly on the marrow, so he didn't think in any event you would
see a big change from month to month. He told them he would be happy to monitor
me through blood work, and he would give them bone marrow slides every three
months, and that was it. My disease is so rare, that I don't think there were
many people falling off the tree saying, "Let me in your study," so they agreed.
Steve Dunn offers another reason to examine the protocol:
I think the most valuable thing in the protocol is to read about the prior
history of this thing, and why they think it's promising, because that will tell
you what the worth of the trial is. What most people hear about is the rate:
"This has a 30 percent response rate in previous trials." But what you really
are looking for in a Phase I or Phase II trial is that it makes the cancer go
away and makes the cancer stay away. The problem is that there are an awful lot
of treatments where the cancer might go away, but it'll grow back. What's really
promising is if it looks like the responses are long lasting and some of these
people are getting quality time.
Steve points out that there's no way of telling what kind of valuable nuggets of
information you might find by a careful perusal of the protocol. He believes
that one of the things he learned may have helped him derive the maximum benefit
from his trial.
When I read the protocol document for my trial, I found that they were very
interested in neurological side effects, and that they would withhold doses of
the treatment if you had any. Knowing this helped me when I was in the
treatment, because they would offer me pain pills, and they would offer me
compazine [a major tranquilizer that also decreases nausea], and they would
offer me sleeping pills. Guess what? All of these things sedate you, and if you
get into enough of a stupor with all of it, they would withhold doses. So I went
really light on all of that stuff. You can't predict what little facts you might
learn in the protocol that would help you get through the treatment better.
The major problem with the protocol is that it's written not at the eighth-grade
level or below, as are most informed consent documents. On the contrary, it's
written for people with MDs or PhDs.
In Childhood Leukemia: A
Guide for Families, Friends, & Caregivers, 2nd Edition, Nancy Keene
lists some of the reasons that parents will wish to obtain protocol documents
related to their children. These reasons apply equally well to adults enrolled
in cancer clinical trials.
Admittedly, for some parents the full protocol could be overwhelming or boring.
There are many parents, however, who throw themselves into research to better
understand their child's illness. These parents may benefit from having a copy
of the study document for several reasons. First, it provides a description of
all the clinical trials that preceded the present one and explains the reasons
the investigators designed this particular study. Secondly, it provides detailed
descriptions of drug reactions, which comforts many parents who worry that their
child is the only one exhibiting extreme responses to some drugs. Thirdly,
motivated parents who have only one protocol to keep track of occasionally
prevent serious errors in treatment. Physicians treat scores of children on
dozens of protocols and sometimes make mistakes. And finally, for parents who
are adrift in the world of cancer treatment, it can return a bit of control over
their child's life. It gives the parents a job to do: monitoring their child's
treatment.
Despite the value of the protocol document to the patient, it's not always easy
to pry it loose from the investigators or their staffs. There are several
reasons that they may be reluctant to show you the protocol. Sometimes it's
misplaced paternalism. You have no medical training, they'll say, and the
protocol is far too complicated for you to understand. You can counter that
objection by pointing out that you or a trusted family member has been forced
into becoming an expert in one narrow area of medicine, that you realize you
might not understand every word, but that you'll ask questions if something
concerns or confuses you.
Another reason the staff might be reluctant to give you the protocol is that
it's a pain in the neck for them. Most protocols are at least seventy to one
hundred pages long, and some are even longer than that. They tend to reside in
thick, loose-leaf notebooks, and it's not an insignificant task to photocopy
something like that. They may say, hey, we're running fifty patients through
this trial, and the protocol is a hundred pages. Suppose everybody asks for a
copy? You can answer this objection by pointing out that you're not fifty
people, you're only one person who needs one copy. And you or a relative can
offer to work the photocopier or take it to a copy shop if staff members don't
have the time. You can also offer to read their copy in their offices, but if
you choose that option be sure not to let yourself be rushed. Take your time,
and come with a pencil and paper so you can take notes.
A more serious obstacle to obtaining the protocol can present itself in some
trials sponsored by pharmaceutical companies. Because these companies are often
concerned about details of their new wonder drug leaking to their competitors,
they often insist that investigators sign confidentiality agreements. This
prohibits investigators from showing the protocol or even discussing certain
details of the trial with others. If a member of the clinical research staff
tells you that you can't have the protocol for this reason, you should
immediately ask to speak to the principal investigator, because people lower on
the totem pole usually don't have the authority to make exceptions to the
confidentiality rule.
Explain to the investigator that there simply isn't enough information in the
informed consent document for you to make a fully informed decision about
participating in the trial. He will likely counter with an offer to answer any
questions you have. Tell him that while you appreciate his willingness to answer
your questions, until you've had a chance to read the protocol you won't even be
able to formulate proper questions. The investigator may well conclude that he
has an ethical obligation to release the protocol to you despite the
confidentiality agreement. If he's still hesitant, offer to sign a
confidentiality agreement yourself. Dr. David Jablons offers his view: "I think
that patients should have complete carte blanche access to the protocol, within
the bounds set by the company."
If the investigator still won't budge, ask to see just part of the protocol. The
introductory sections tend to be the parts that are most valuable to clinical
trial participants, and the investigator may be more willing to show you this
one section than the whole thing. If even that suggestion won't move him,
contact someone on the Institutional Review Board (IRB), whose telephone number
will appear on the informed consent document. Explain to the IRB member why you
want to see the protocol. The IRB may direct the investigator to make an
exception to the confidentiality rule.
Throughout all of this, be pleasant and polite but firm in your resolve to
obtain the protocol. It would most likely be counterproductive to become angry
or confrontational, and it would be an especially bad idea to suggest that the
investigator was withholding the protocol because he had something to hide.
If you are unable to obtain the protocol even after applying your best efforts,
you may wish to draw up an especially long and detailed list of questions for
the investigator. Be sure to ask for all the information you expect you may have
learned by reading the protocol.
No matter how desperate you are to enter a clinical trial, you should make sure
all your questions are answered before proceeding. Lydia Cunningham Rising tells
a story that illustrates this point nicely. When Rising was searching for a
clinical trial for her ex-husband, she found only two physicians doing research
on his type of brain cancer. One of them was very hard to reach, and when she
finally did get him on the phone,
He was very evasive. He would not answer my questions. When I tried to find out
how many people he'd treated and how they did, he would never give me a straight
answer. The other doctor told me that he'd treated nine patients and two were
still alive after a few years. Joe would be number ten. He just laid it all out,
so we went there. Six or seven years later I came across a journal article
written by the doctor who had been evasive. Of the sixty-five patients he
treated, not one survived longer than a year. Now you know why the man didn't
tell me. If anyone is being evasive, he may well have something to hide.
It's a good idea to bring a tape recorder to meetings with the investigator or
trial administrators in which you ask these questions. It can be difficult to
take notes while listening with full concentration, and a tape will contain a
full record of everything that was said. Be sure to inform everyone in the room
that you intend to tape the conversation; in many states it's illegal to record
people without their knowledge. If you don't have access to a tape recorder, go
with a friend or family member and ask that person to take notes so you can
devote your full attention to the discussion.
