SIBYL: obServation of Therapy Response With lIquid BiopsY evaLuation

Recruiting

• Conditions: Non-small Cell Lung Cancer; Colorectal Cancer; Breast Cancer

• Registration Number: NCT05935384
• Lead Sponsor: Guardant Health, Inc.

Brief Summary

The purpose of SIBYL is to generate clinical validity data for the ability of a future version of Guardant360 developed by Guardant Health to measure response to systemic therapy in patients with unresectable advanced solid tumors. It is necessary to collect clinical data points and treatment outcomes in order to demonstrate clinical validity for longitudinal monitoring with ctDNA and correlation of ctDNA dynamics with therapeutic response, as evaluated by standard methods, including RECIST 1.1 and CT scan measurements.

Primary Outcome Measures

Name	Time	Method
Sensitivity of ctDNA to Detect Disease Progression	6 years	The Primary Endpoint, sensitivity of ctDNA to detect disease progression, will be evaluated from all eligible subjects within the primary study cohorts (breast cancer, NSCLC, or CRC)

Secondary Outcome Measures

Name	Time	Method
Lead Time	6 years	Lead time: defined as the interval between ctDNA detection or increase and clinical detection of disease progression
RECIST Response	6 years	RECIST v1.1 response: defined as the tumor response to treatment as measured by restaging scans in subjects who have increasing or decreasing ctDNA quantities before the time of scan and correlating this change with the clinical response
Progression-Free Survival (PFS)	6 years	PFS: defined as the quantitative changes in ctDNA that correlate or associate with participant's progression free survival on each line of SOC therapy
