bespoke study of ctdna guided immunotherapy

Conditions: Colorectal Cancer; Melanoma; Non-small Cell Lung Cancer

Summary: this is a prospective data collection study of patients with advanced solid tumors who will receive standard of care immunotherapy (io) and will be monitored with signatera™ testing. signatera™ test will be performed at baseline and during routine care. the test results will be part of assessing tumor response. the correlation between signatera™ test results and subsequent treatment decisions will be examined to compare actual treatment delivered against treatment decisions potentially impacted by signatera™ results. treatment administered, tumor assessment results, time to progression, overall survival, physician questionnaires, and patient-reported outcomes will be collected/recorded.

primary objective: ● to examine the impact of signatera™ on clinical decision-making regarding continuation, discontinuation, escalation, or de-escalation of immunotherapy. secondary objective: ● to prospectively evaluate the utility of signatera™ as a tool to detect early evidence of response or progression in patients with advanced solid tumors receiving immune checkpoint inhibitors.
