A digital therapeutic for proactive monitoring of patients on immune checkpoint inhibitor therapy for early detection of immune-related adverse events

101 Background: Immune-related adverse events (irAEs) occur frequently in patients receiving immuno-oncology therapy. irAEs are heterogeneous and unpredictable. Experience at academic cancer centers has shown that (1) education of patients and families must be continuous; (2) experience of the care team can improve outcomes; and (3) close monitoring of patients in between visits translate into early detection and timely intervention. Most oncologists in lower volume community practices have not gained the experience nor have the resource for continuous education frequent proactive monitoring. Methods: In addition to self-monitoring by patients on chemotherapy to improve outcome (Basch ref), we hypothesized that adoption of evidence-based management is critical as well. Thus, we have developed ApricityRx, a digital therapeutic (DTx) for end-to-end irAE management, which not only engages patients in frequent self-nonitoring but also activates the oncology team for timely intervention. In brief, ApricityRx (i) enables intelligent monitoring by educating and guiding patients to track specific expert-prioritized symptoms in between clinic visits; (ii) facilitates early recognition by prompting triage at the right time and (iii) recommends evidence-based management based on consensus guidelines. Results: In a community cancer center, 16 patients have been enrolled (44% consent rate) in an IRB approved feasibility trial to evaluate the usability of ApricityRx as a tool for frequent monitoring and timely triage. Over 435 unique longitudinal records containing over 34K data points, including patient-reported outcome (PRO) and clinical care data (EMR), were generated. Interim analyses have shown that primary and secondary endpoints were met. Detailed results will be presented. Conclusions: ApricityRx has shown usability in a low-volume community-based oncology practice to facilitate proactive monitoring and tinely triage by the oncology team. Further, ApricityRx has enabled not only generation of high-resolution patient-reported outcome (PRO) data, but also aggregation of PRO and real-world EHRs data for downstream analyses.
