The National Academy of Sciences is a private, nonprofit, self-perpetuating society
of distinguished scholars engaged in scientific and engineering research, dedicated to
the furtherance of science and technology and to their use for the general welfare.
Upon the authority of the charter granted to it by the Congress in 1863, the Acad-
emy has a mandate that requires it to advise the federal government on scientific
and technical matters. Dr. Ralph J. Cicerone is president of the National Academy
of Sciences.
The National Academy of Engineering was established in 1964, under the charter
of the National Academy of Sciences, as a parallel organization of outstanding
engineers. It is autonomous in its administration and in the selection of its members,
sharing with the National Academy of Sciences the responsibility for advising the
federal government. The National Academy of Engineering also sponsors engineer-
ing programs aimed at meeting national needs, encourages education and research,
and recognizes the superior achievements of engineers. Dr. Charles M. Vest is presi-
dent of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of
Sciences to secure the services of eminent members of appropriate professions in
the examination of policy matters pertaining to the health of the public. The Insti-
tute acts under the responsibility given to the National Academy of Sciences by its
congressional charter to be an adviser to the federal government and, upon its own
initiative, to identify issues of medical care, research, and education. Dr. Harvey V.
Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sci-
ences in 1916 to associate the broad community of science and technology with the
Academy’s purposes of furthering knowledge and advising the federal government.
Functioning in accordance with general policies determined by the Academy, the
Council has become the principal operating agency of both the National Academy
of Sciences and the National Academy of Engineering in providing services to the
government, the public, and the scientific and engineering communities. The Coun-
cil is administered jointly by both Academies and the Institute of Medicine. Dr.
Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of
the National Research Council.

Preface
Clinical trials that test the safety and therapeutic benefit of drugs and
other treatments are essential for developing new and improved therapies
for patients with cancer. However, the system for conducting cancer clini-
cal trials in the United States is approaching a state of crisis. Changes are
urgently needed if we are to continue to make progress against the second
leading cause of death in this country. If the clinical trials system does not
improve its efficiency and effectiveness, the introduction of new treatments
for cancer will be delayed and patient lives will be lost unnecessarily.
For the past 50 years, the Clinical Trials Cooperative Group Program
supported by the National Cancer Institute (NCI) has played a critical
role in testing new cancer therapies. The Program comprises a network of
cancer centers and community oncology practices across the country that
develops cancer clinical trials and enrolls patients in those studies. More
than 25,000 patients and thousands of clinical investigators participate in
these clinical trials annually. The knowledge gained from the large-scale,
multicenter trials conducted by the Cooperative Groups has been instru-
mental in establishing the therapies that are now routinely used to treat
patients with cancer.
Cooperative Group trials have diminished the impact of cancer on
many fronts. Most obviously, they have identified superior treatment strat-
egies that have led to longer lives. Findings from pediatric cancer trials,
largely carried out by Cooperative Groups over the past four decades,
have boosted childhood cancer cure rates from less than 10 percent in the
1950s to nearly 80 percent today. Cooperative Groups have performed the
definitive studies of many of the standard treatments for adult cancers as

x PREFACE
well and have played a major role in evaluating innovative therapies, such
as those targeted to tumors with specific genetic characteristics and those
designed to halt tumor growth by blocking the blood vessels that support
the tumor rather than by directly killing cancer cells.
In addition to identifying treatments that prolong life, the Coopera-
tive Groups have also given attention to the important issue of quality
of life. Many important studies have focused on minimizing the adverse
consequences of cancer treatments. A landmark example was the trial
demonstrating that breast-conserving surgery plus radiation was as effec-
tive at eradicating early-stage breast cancer as radical mastectomy. Other
Cooperative Group trials have shown that some less intensive regimens for
pediatric cancers could control cancer while reducing the risks of long-term
harms from the highly toxic therapies typically used to treat those cancers.
Finally, the Cooperative Groups have also addressed cancer prevention.
One important trial showed that by taking a drug such as tamoxifen, breast
cancer incidence could be reduced by 50 percent for women at high risk for
breast cancer over a 5-year period.
Publicly sponsored trials fill an important information void by conduct-
ing head-to-head comparisons of different treatment regimens, combining
treatments, and investigating whether drugs approved for the treatment of
one type of cancer can be used to effectively treat other types of cancer,
all of which are far less likely to be pursued by pharmaceutical companies.
However, the NCI Cooperative Group Program is falling short of its full
potential to improve the quality of care that cancer patients receive. An
accumulation of problems is hampering progress, just at a time when new
knowledge about the genetic and molecular underpinnings of cancer has
created opportunities for designing trials with new, targeted anticancer
agents. Increasingly, biomarkers (predictors of a response to a particular
therapeutic intervention) can be used to select which treatment strategy is
most likely to benefit individual patients.
One major problem is the complex system of designing, reviewing, and
initiating Cooperative Group clinical trials, which has become a lengthy
and redundant process typically requiring years to complete. In attempt-
ing to optimize the effectiveness and safety of trials, proposals often are
redrafted and recycled by multiple stakeholders from academic institutions,
federal agencies, institutional review boards, and industry. This results
in frustration and a perception that stakeholders are working at cross-
purposes. In addition, the system lacks an adequate process for prioritizing
trials and selecting those most likely to be successful. Finally, when there
are long delays in designing and initiating clinical trials, the slow accrual of
patients is often the result. Only about 60 percent of NCI-sponsored trials
are actually completed and published, which is a terrible waste of human
and financial resources.

PREFACE
Another major problem is the inadequacy of NCI funding for Coop-
erative Group clinical trials. As much as half of the cost of clinical trials
today are borne by the clinical investigators and clinical care providers who
design and carry out these important studies. Almost universally, investiga-
tors are compelled to seek supplemental support from outside sources, such
as pharmaceutical companies. The problem is further compounded by the
increased costs of trials because of the opportunity to measure biomark-
ers in a patient’s cancer and use them to predict and monitor appropriate
therapy. Added to these challenges is the relatively low value placed on
Cooperative Group trials by academic institutions in evaluating faculty
accomplishments and by the NCI in evaluating Cancer Center achieve-
ments; this discourages physician participation. Moreover, the nonexperi-
mental costs of care in clinical trials are not borne by some insurance plans,
which significantly hinders patient participation.
In this report, developed at the request of the director of the NCI, an
Institute of Medicine committee makes recommendations to address these
challenges. Stepping back to gain a comprehensive perspective, the com-
mittee took a broad look at the needs and goals of all stakeholders in the
current cancer clinical trials system and has made recommendations for
changes across the board that will improve the efficiency and effectiveness
of the system. Our goal was to preserve the historical strengths of the Coop-
erative Group Program while recommending improvements to components
that are not working well.
Some functions will need to be better integrated, and others must be
carried out in parallel rather than in series to reduce the amount of time lost
to repetitive steps. The report stresses the need to consolidate functions and
processes within the clinical trials network, streamline oversight, enhance
collaboration, select and prioritize trials more stringently, fully fund the
most innovative and promising studies, and open and complete trials with
greater speed. There must also be agreement on strict deadlines that should
be met at each step along the way. The committee further recommends
(with regret) that the number of trials be reduced if adequate funding to
pay for the highest-priority studies is not available.
Changing any particular component of the system will not suffice. All
participants and stakeholders, including physicians, patients, and health
care insurers, as well as the NCI and regulatory agencies, must reevaluate
their combined roles and their contributions to a successful, streamlined
process for carrying out Cooperative Group clinical trials that will improve
the care of patients with cancer. Collectively, implementation of the recom-
mendations presented in this report will lead to the faster approval and
adoption of new therapies, new discoveries upon which to base future
studies, and the accelerated translation of new knowledge into beneficial
therapies for patients with cancer. The committee also endorses recom-

mendations recently made by NCI’s Operational Efficiency Working Group,
which aim at achieving similar goals and which are incorporated as an
appendix to this report.
The members of the committee wish to express their gratitude to the
staff of the Institute of Medicine, with whom we have worked so closely
for more than a year. Special thanks are due to Sharyl Nass, whose skills
in assimilating information and formulating our proposals into systematic
recommendations are unparalleled in our collective experience, and to Erin
Balogh, who was instrumental in helping the committee draft the chapters
of the report. We hope that our report will stimulate and guide the Coop-
erative Group Clinical Trials Program to enhance its critical role in advanc-
ing treatments for patients with cancer.
