BESPOKE Study of ctDNA Guided Immunotherapy

Natera, Inc.290 enrolled

Overview

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.

Outcomes

Primary Outcomes

Examine the impact of SIGNATERA on treatment decisions on tumor assessment timepoints after initiation of immunotherapy

Percent of patients who have their immunotherapy treatment regimen changed due to post-treatment SIGNATERA ctDNA test result

Time frame: 2 years

Secondary Outcomes

To determine progression free survival according to ctDNA change

Compare progression free survival, defined as the duration of time between enrollment and an increase in severity of disease as determined by patient's treating physician, between groups determined by change in ctDNA

Time frame: 2 years

Determine overall survival according to ctDNA change

Compare overall survival, defined as the duration of time between enrollment and death for any reason, between groups determined by change in ctDNA

Time frame: 2 years

Determine response rate according to ctDNA change in cases with progression of disease on first or second tumor assessment and who continue treatment.

Compare percentage of patients that experience partial or complete response during the study, between groups determined by change in ctDNA

Time frame: 2 years

To determine progression free survival according to ctDNA change in cases who achieve stable disease on first tumor assessment.

Compare progression free survival between groups determined by change in ctDNA

Time frame: 2 years

To determine duration of response according to ctDNA change in cases who achieve partial response or complete response as best overall response.

Compare duration of response, defined as the length of time from initial response to disease progression, between groups determined by change in ctDNA

Time frame: 2 years

To determine percentage of patients with at least 6 months of durable clinical response according to ctDNA change in patients who achieve at least partial response on best tumor assessment.

Among all patients that are clinically identified to experience partial or complete response, percentage that have at least 6 months durable clinical response as determined by ctDNA change

Time frame: 2 years

Determine the impact of SIGNATERA on the confidence in immunotherapy treatment decisions based on the number of patients in which treating physician reports SIGNATERA made them more confident in immunotherapy treatment regimen

Percent of patients whose treating physician reported that SIGNATERA result made them more confident in selected immunotherapy treatment regimen

Time frame: 2 years

Determine the impact of SIGNATERA in informing immunotherapy treatment decisions

Percent of patients whose immunotherapy treatment regimen was changed as a result of SIGNATERA and/or whose treating physician reported that SIGNATERA result made them more confident in selected immunotherapy treatment regimen

Time frame: 2 years

Determine the impact of SIGNATERA on patient reported outcomes

Assess patient anxiety levels and wellbeing in patients receiving SIGNATERA ctDNA test results. Patient responses to patient reported outcome questionnaires: EORTC QLQ-C30 Assess if SIGNATERA makes patients feel that they are receiving the right treatment and determine if patients will continue to use Signatera in the future to monitor their cancer.
