for Lung Cancer

Personalized, tumor-informed testing for molecular residual disease (MRD) to inform lung cancer care across the treatment journey. Signatera™ is a test that measures ctDNA for lung cancer to monitor recurrence and tumor growth. With ctDNA testing, doctors and their patients can make better-informed decisions about care.

Evaluate Response to ICI Treatment

ICIs (immune checkpoint inhibitors) are FDA-approved with guideline recommendations across all treatment settings in lung cancer (neoadjuvant, adjuvant, locally advanced, metastatic).4

The Signatera™ Residual Disease Test was evaluated in the INSPIRE trial, a randomized, prospective study in patients with advanced or metastatic solid malignancies receiving an anti-PD-1 treatment:3

  • An increase in ctDNA levels from baseline to week 6 strongly predicted disease progression and nonresponse to treatment.3

  • Overall survival was 100% in patients who experienced ctDNA clearance for at least one on-treatment time point.3

Inform Your Lung Cancer Treatment Approach With Signatera™

Monitoring circulating tumor DNA (ctDNA) with Signatera™ across the treatment journey can answer important clinical questions and inform treatment decisions.

Do More With Less Tissue

One tumor sample – two tests

Add the Altera™ tumor genomic profiling test when you order Signatera™ to get clinically relevant biomarkers (eg EGFR, KRAS, ALK, ROS1, MSI, TMB) and MRD monitoring with no additional sample.

Reassure Your Patients Living With Lung Cancer

After JoAnn was diagnosed with lung cancer, Signatera™ detected a rise in her ctDNA levels, alerting her oncologist to a progression that was not scannable.

Watch JoAnn’s story to learn how she and her oncologist added Signatera™ testing to their toolbelt to help closely monitor her cancer.

“I want to know. The more you know, the better off you are.” – JoAnn, living with lung cancer
