Promoting Accrual of Older Patients with Cancer to Clinical Trials: An Alliance for Clinical Trials in Oncology Member Survey (A171602)

Background. There are multiple known individual-and practice-level barriers to enrollment of older patients with cancer to clinical trials, but little is known about how the clinical research workforce feels about potential higher-level strategy changes aimed to promote increased enrollmentofolder patients. Subjects, Materials, and Methods. We invited all 11,351 Alliance for Clinical Trials in Oncology ("Alliance") members to participate in an anonymous, web-based survey to examine awareness of current accrual patterns for older patients to clinical trials, to ascertain consensus on how to tackle enrollment challenges, and to provide the impetus for high-level changes to improve clinical trial accrual of older patients with cancer. Results. During the period from February 28, 2017, to June 16, 2017, 1,146 Alliance members participated (response rate= 10%), including a national diverse sample of physicians, nurses, administrative/clinical research staff, and patient advocates with representation from community, academic, and rural sites. Overall, one third felt that >50% of clinical trial enrollees should be age >= 65, and 64.9% felt the Alliance could improve upon enrollment of older patients. The four most commonly ranked strategies to improve enrollment of older patients were creating more dedicated trials for this population (36.3%), minimizing exclusion criteria focused on comorbidity (35.5%), developing independent strategies for those aged >= 65 and for those aged >= 70 (33.2%), and requiring that most/all Alliance trials have a specific expansion cohort of older patients (30.0%). Conclusion. We anticipate that the recommendations from > 1,000 Alliance members will continue to propel important strategy changes aimed to improve accrual of older patients with cancer to clinical trials.
