group prevents segments of the population from benefiting
from advances achieved through clinical research, creates
uncertainties over the applicability of research findings and
has proven to develop lifesaving drugs that work for some
ethnic populations but not others.
(4) Conversely, some drug trials are canceled because
they do not show promise for the current homogenous study
population of patients but could be beneficial to other
ethnicities who are not receiving the trial drug because of
poor participation rates.
(5) Diverse patient participation in cancer clinical
trials depends, in part, on whether a participant can afford
ancillary medical and other costs, including transportation
for clinical visits required by trial participation, which
are not covered by standard of care, or lodging during the
course of his or her participation. A national study in 2015
found that patient households making less than $50,000
annually were almost 30% less likely to participate in
clinical trials.
(6) Another barrier to cancer clinical trial
participation is the cost of travel, lodging and other
expenses for a patient's travel companion, including a family
member, friend, health care provider or chaperones that
attend cancer clinical trial treatments to provide emotional,
physical and mental support to the trial participant. Some
trial participants are too old, too young or too ill to
simply travel on their own.
(7) Cancer clinical trials often only cover the actual
cost of the drug being tested and very rarely the direct
costs of participation by a patient-subject. There are often
significant expenses associated with enrollment in a clinical
trial that are not covered by the clinical trial site or
sponsor. These include travel expenses to and from the
clinical sites whether by air, car, bus, train, taxi or
public transportation along with the travel costs of parking,
car rental, gas, tolls and lodging.
(8) This disparity threatens one of the most basic
ethical underpinnings of clinical research, the requirement
that the benefits of research be made available equitably
among all eligible individuals.
(9) According to the National Cancer Institute, Cancer
Clinical Trials Resource Guide, some of the barriers
preventing individuals, with cancer or at high risk of
developing cancer, from participating in clinical trials are
direct and indirect financial and personal costs, including
travel.
(10) Some corporations, individuals, public and private
foundations, health care providers and other stakeholders are
hesitant to contribute to or accept funds from programs that
are organized to alleviate financial burdens faced by
patients who wish to participate in clinical trials and their
