Abstract
PROJECT SUMMARY/ABSTRACT
Cancer patient participation in therapeutic clinical trials is essential to the development and evaluation of new
cancer treatments to improve patient survival, outcomes, and quality of life. However, investigators and
institutions often fail to recruit the number of patients required to answer the study’s question or provide
generalizable results, limiting the advancement of cancer care. Trial enrollment rates among U.S. cancer
patients remain persistently low. It is estimated that 77% of US cancer patients are not enrolled to trials due to
being treated at sites with no trial options for them. Of the remaining 23% of all patients treated at facilities with
available trials, only 8%, or just over 1 in 3, are enrolled. Rural areas are characterized by uneven and
insufficient accrual of patients onto therapeutic clinical trials. Current solutions to supporting clinical trial
enrollment include big data initiatives, such as precision oncology protocols, designed to reduce structural
barriers by matching patients to trial opportunities within large clinical trial networks. Patient decision aids
administered at the time of invitation to a specific trial are designed to help patient better understand and make
informed decisions about joining trials
. Despite the proliferation of these efforts, their efficacy in increasing trial
enrollment is inconsistent and trial enrollment rates remain stagnant. Research from our group and others has
shown that patients’ trial enrollment decisions are not just based on their views of a specific trial opportunity but
also factors such as misunderstanding, mistrust, negative attitudes, and poor communication skills which can
limit patients’ participation in clinical trial conversations and decision making. Our premise is that interventions
are needed to extend beyond prevailing strategies of offering decision aids or education at the time of trial
invitation to also proactively preparing patients to have meaningful conversations and make informed decisions
if presented with a trial opportunity. We have developed and experimentally tested a set of evidence-based
message strategies, grounded in health communication principles and behavior change theories, which can be
effective at improving patient understanding and communication skills, even among those with mistrust or
negative attitudes toward research. We propose to assemble these evidence-based components into an
interactive, game-based educational intervention to prepare patients to engage in clinical trial conversations
and informed decision-making if an opportunity to join a trial emerges during their treatment. The planning
studies in this R34 application are designed to support a future trial by completing these Specific Aims:
1) to
apply user-centered design and iterative development methods to produce an intervention that integrates
evidence-based messaging strategies into a game package
; 2) to conduct a pilot study of the intervention in
the field; and 3) to collect prospective data from medical records and self-report patient survey related to
clinical trials.
