Abstract
e23314 Background: Evaluating immunotherapy approaches is consistently performed in melanoma, a forefront cancer in immunotherapy responsiveness. Although immune checkpoint inhibitors (ICIs) showed the highest significant survival benefits in melanoma, 50% of patients experience recurrence/refractory disease, and ~59% develop grade 3/4 immune-related adverse events (irAEs). Thus, understanding the disease's natural history, exploring biomarkers of response/toxicity, and identifying the efficacy/safety of immunotherapy using real-world data is warranted. Methods: We established a centralized pro-/retrospective database on Research Electronic Data Capture (REDCap), encompassing patients' demographics/comorbidities, disease risk factors, clinicopathological parameters, genomic/immune profiling, treatment modalities, tumor outcomes, irAEs, and patients’ reported outcomes (PROs). Additionally, to streamline data collection and minimize the required time, effort, and cost for manual retrieval, we developed an automated pathway for data capture using MD Anderson Cancer Center (MDACC) electronic data capture (EDC) tools which pull clinical data from EPIC. Data quality will be validated by comparing it to manually retrieved data from an ongoing study of melanoma patients treated with ICIs in the adjuvant setting (NCT04990726). Results: A total of 4074 immunotherapy-treated melanoma patients were identified. We automatically captured demographics and laboratory values at predefined time points from REDCap, along with PROs using validated electronic self-reported questionnaires already built in REDCap. We also automatically captured family history, comorbidities, pathology data, and cancer treatments from the Data Management Initiative (DMI) validated software that automatically captures data from 12 various institutional sources that complement each other, including Radiation Oncology Database, the Biospecimen Information Management System,...etc. Moreover, genomic data were automatically pulled from the Molecular and Clinical Data Integration Platform for 1850 patients. Automated capture of tumor response and irAEs according to the Response Evaluation Criteria in Solid Tumors 1.1. and Common Terminology Criteria for Adverse Events version-5, respectively are currently ongoing and will be presented. Conclusions: Integrating EDC tools demonstrated accurate real-time data capture and minimized the manual retrieval burden. Our immunotherapy-treated melanoma patients’ cohort provides a comprehensive and a valuable resource for exploring the safety signals and efficacy of various immunotherapeutic approaches beyond clinical trials.
