Assessments self-administered via smart phone-based apps can gather patient wellness data; however, data regarding app utilization in clinical trials are limited. This study evaluated engagement with a self-administered wellness app as a supplemental tool to assess quality-of-life (QoL) in study BGB-3111-215 (NCT04116437), which included patients with B-cell malignancies treated daily with oral zanubrutinib.

This exploratory analysis evaluated the feasibility of using a voluntary device-based, self-administered activity and QoL questionnaire app (Medable, California, USA) in clinical trial patients. Feasibility was measured by rates of consent, utilization, and compliance. Consent was assessed by the percentage of patients who agreed to use the app. Utilization was assessed by the percentage of patients who engaged with the app. Compliance was assessed by actual versus scheduled engagements. The app also included passive activity tracking and a six-minute walk test.

As of 1 September 2022, 78 patients had enrolled in the study (median age 71 years) and 20 had consented to participate (26% consent rate). Eleven patients (median age 65 years) engaged with the app at least once (14% utilization rate; n=11 for the questionnaire; n=7 for the walk test). Engagement occurred a median two times (range 1 to 17) for the questionnaire and a median seven times (range 1 to 15) for the walk test. Four patients engaged with the questionnaire and six patients engaged in the walk test beyond week 12. Passive activity was collected for eight patients beyond week 12. Among patients who engaged with the QoL questionnaire and walk test, compliance rates were 18 and 21 percent, respectively.

This initial study showed that a subset of patients was willing to participate in the self-administered QoL questionnaire and activity tracker. Further comparison of app results and clinical trial findings are ongoing to explore factors affecting utilization and compliance rates.
