About

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.

Full description

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.

Enrollment: 290 patients

Trial design

290 participants in 2 patient groups

Prospective arm

Description:

Patients will receive SIGNATERA™ test results and the immunotherapy treatment regimen, dosing schedule, duration of treatment, number of cycles, and modifications during treatment will be at the discretion of the HCP. Patients will be followed for up to two years with periodic whole blood collection. Treatment administered, disease-free survival, overall survival, time to recurrence, physician questionnaires and patient-reported outcomes will be recorded.

Control arm

Description:

Control cases must have undergone immunotherapy treatment and have follow-up data available in their medical record at the participating site for two years following initiation of immunotherapy or death.
