The Value of Liquid Biopsy in Identifying Actionable Alterations

LCMC LEADER neoadjuvant screening trial: LCMC4 evaluation of actionable drivers in early stage lung cancers. Abstract #TPS8596.

In collaboration with the Lung Cancer Research Foundation, the Lung Cancer Mutation Consortium, and Memorial Sloan Kettering Cancer Center, this Trial in Progress abstract details the umbrella trial design of the LCMC4 Evaluation of Actionable Drivers in EaRly-Stage Lung Cancer (LEADER) clinical trial. Foundation Medicine’s tissue-based CGP test, FoundationOne®CDx, and its blood-based CGP test, FoundationOne®LiquidCDx, will both be used in the LEADER trial to screen for 10 actionable driver mutations in 1,000 patients with high-risk, resectable NSCLC who are candidates for neoadjuvant therapy. Results will enable selection of neoadjuvant therapy and enrollment onto independent therapeutic trials with genomically matched neoadjuvant treatment, standard therapies, or other trials if no driver is detected.

CtDNA shed as a tool to select immune checkpoint inhibitors (ICPI) with or without chemotherapy for patients (pts) with advanced non-small cell lung cancer (aNSCLC). Abstract #9045.

Using the CGDB, this study with Gustave Roussy Cancer Center investigated circulating tumor DNA (ctDNA) shed as an indicator to support treatment selection for patients with advanced NSCLC. Researchers found that elevated plasma tumor fraction (TF) can identify patients at risk of early progression on immune checkpoint inhibitors (ICPI) who may benefit from chemotherapy in addition to an ICPI. In patients with low/intermediate TF, the study found that outcomes on ICPIs alone are similar to those receiving both chemotherapy and ICPI treatment, suggesting TF’s ability as a non-invasive tool to identify patients for single-agent ICPI.

Genomic landscape of acquired resistance to targeted therapies in patients with solid tumors: a study from the National Center for Precision Medicine (PRISM). Abstract #3016.

Researchers from Gustave Roussy Cancer Center and Institut Bergonié set up a study using FoundationOne®Liquid CDx to detect ctDNA in an effort to characterize the landscape of secondary resistance mechanisms in patients with solid tumors. While many targeted therapies are approved for treatment in solid tumors, acquired resistance to these therapies remains as a barrier limiting the ultimate effectiveness of these treatments. Researchers reported that polyclonal secondary genomic alterations represent a frequent clinical resistance mechanism that may explain the low rate of sustained complete remission for patients treated with targeted therapies.

The Power of Real-World Genomic Data to Shape the Future of Cancer Care

A real-world (rw) evidence study quantifying the clinical value of multi-gene testing in early-stage lung adenocarcinoma (LUAD). Abstract #8525.

In collaboration with Cleveland Clinic Cancer Center and Flatiron Health, this study used the CGDB to assess the potential value of CGP in early-stage lung adenocarcinoma (LUAD). Researchers found that CGP of early-stage LUAD can identify EGFR, ALK, ROS1, RET and other drivers and enable appropriate selection of targeted therapies and timely use of effective first line therapy at recurrence. By avoiding the use of ICPIs in patients unlikely to respond, CGP could represent a way to avoid ineffective treatment and risk of tyrosine kinase inhibitor (TKI)-associated toxicity.

Biomarker associations of immune checkpoint inhibitor versus chemotherapy effectiveness in first-line metastatic endometrial carcinomas: A real-world study. Abstract #5596.

Using real world data from the CGDB, this study in partnership with the Yale School of Medicine evaluated TMB greater than 10 mutations per megabase and MSI-high as predictive biomarkers for ICPI benefit in comparison to standard of care chemotherapy in first line metastatic endometrial cancer (mEC). More favorable time to next treatment and overall survival were observed on ICPI versus chemotherapy in first line treatment among those with high TMB and/or MSI-high, but not those without. The results of this study suggest that a randomized controlled trial in this setting using these biomarkers has a favorable chance of success to develop a chemotherapy-sparing first line option for patients with mEC.

Clinical and genomic characteristics of pts with durable benefit from immune checkpoint inhibitors (ICPI) in advanced non-small cell lung cancer (aNSCLC). Abstract #9048.

In collaboration with Dana-Farber Cancer Institute, this study queried the CGDB to better understand patients with advanced NSCLC who had a durable response to ICPIs. The two-year mark has increasingly become a milestone in progression-free patients with advanced NSCLC, with a subset experiencing ongoing disease control even after discontinuing active treatment. In a cohort of 4,030 advanced NSCLC patients, 4.6% were free of progression or treatment failure at 24 months, with a median overall survival of almost 5 years. 41% of those patients stopped immunotherapy usage before the two-year mark. Researchers also found that elevated TMB was associated with durable benefit on ICPIs, as well as prolonged progression-free survival after the 2-year mark and deserves further investigation as a biomarker for prolonged benefit from ICPIs in advanced NSCLC.

Ancestry-based differences in gene alterations in non-small cell lung cancer: Real-world data using genetic ancestry analysis. Abstract #9125.

In this study, researchers investigated alteration prevalence in a large real-world NSCLC cohort, stratified by genetic ancestry. Together with Juntendo University Graduate School of Medicine and others, the study looked at FoundationCore®, Foundation Medicine’s robust real-world dataset, to reveal ancestry-associated differences in genomic alterations in NSCLC. Age and sex were also associated with differences in prevalence of gene alterations and immunotherapy-associated biomarkers, such as high TMB status.

Real-world (rw) analysis of quantitative MET copy number (CN) as a biomarker in advanced NSCLC (aNSCLC). Abstract #9123.

Researchers used real-world data from the CGDB to explore the genomic landscape of MET amplification in NSCLC and its association with outcomes to MET TKIs. In partnership with the University of Colorado, CGP results from 64,521 tissue and 5,177 blood-based NSCLC samples were queried for MET amplification, which was detected in 3.3% of tissue samples and 3.2% of high TF blood samples. MET amplification was found to be associated with response to MET TKIs. In TKI-naïve patients, MET copy number was negatively correlated with the presence of a concurrent NSCLC driver, suggesting that further studies evaluating MET copy number as a predicative biomarker for MET TKIs, and as an indicator of MET dependence to aid therapy section, are warranted.

Activating MET kinase domain mutations define a novel molecular subtype of non-small cell lung cancer that is clinically targetable with the MET inhibitor elzovantinib (TPX-0022). Abstract #9124.

In this study conducted in partnership with Dana-Farber Cancer Institute and Turning Point Therapeutics, researchers investigated a novel, actionable subtype of NSCLC characterized by activating MET tyrosine kinase domain (MET-TKD) mutations in the absence of METex14 mutations. Looking at a multi-institutional dataset of cancers that underwent genomic profiling, including FoundationCore®, researchers found that potentially actionable MET-TKD mutations represent a novel genomic subtype in 0.6-0.9% of NSCLC and occur in the absence of other known drivers in a subset of cases.
