Initial results of a new clinical trial matching service to increase patient participation

Methods: Data from CTMS constituents and follow-up information describing enrollment status and barriers to trial participation are reviewed. Results: During 15 months of operation the CTMS provided information to 10,997 individuals; 7,521 (68.39%) used the website only, and 3,476 (31.61%) also contacted the ACS call center. Among 981 of the 3,476 (28.22% the basis of analyses below) who consented to and could be reached for follow-up and who answered the question on enrollment status, 119 (12.13%) enrolled in a CT. Trial phase was known for 74 enrollees (phase I: 17 [22.97%]; II: 36 [48.65%]; III: 21 [28.38%]; IV: 0 [0%]). Enrollment was negatively (p < 0.05) associated with poor ECOG functional status and black race, and was positively related to disease stage. Among the 757 individuals with available disease site and enrollment information, those with stomach cancer accounted for the most enrollments (25, 24.75% of all enrollments); followed by melanoma (12, 11.88%) and kidney, renal pelvis, bladder, ureter and urethra (also 12, 11.88%), and breast cancer (11, 10.89%). The highest enrollment rates (% enrollees among individuals with available follow-up) were for multiple myeloma/plasma cell disorders (4/14, 28.57%), melanoma (12/49, 24.49%), primary CNS malignancy (5/31, 16.13%), and soft tissue sarcoma (6/45, 13.33%). The following barriers were significantly associated with non-enrollment: ‘I cannot travel to clinical trial site,‘ ‘I cannot find a clinical trial using the modality or treatment I want,‘ ‘My physical activity level is too low,‘ and ‘I do not have measurable disease or am cancer-free.‘ Conclusions: 12% of CTMS participants with available follow-up data for enrollment status participated in a CT. Several determinants of CT participation were identified. Strategies for eliminating racial disparities, facilitating transportation, and increasing participation among patients with earlier stage disease and more common tumor types must be developed and implemented.
