Caris Life Sciences (NASDAQ: CAI) launched a multimodal AI-driven molecular signature to guide first-line treatment selection for a subset of PD-L1 ≥50% non-small cell lung cancer (NSCLC) patients.

The signature uses Whole Exome Sequencing, Whole Transcriptome Sequencing and clinical data via the proprietary CodeAI platform to predict which patients benefit from adding chemotherapy versus those harmed by it. Caris notes the insight is proprietary and available to Caris customers; the company previously received FDA approval in November 2024 for its WES/WTS tissue assay MI Cancer Seek.

Analysis

This announcement adds a new NSCLC-focused AI signature that uses WES/WTS and clinical data to distinguish which high PD-L1 patients benefit—or are harmed—by adding chemotherapy. It builds on Caris’ MI Cancer Seek assay, FDA approved in November 2024, and extends a growing AI portfolio across multiple tumor types. Investors may watch for real-world adoption, integration into clinical guidelines, and further outcomes data as key markers of how this capability translates into durable commercial impact.

7 terms
non-small cell lung cancer (NSCLC) medical
"a subset of mono-immunotherapy eligible non-small cell lung cancer (NSCLC) patients"
A common group of lung cancers that arise from the lungs’ cell lining and grow in ways different from the faster-spreading “small cell” form; think of it as several related varieties of the same illness rather than one single disease. It matters to investors because diagnosis rates, new drugs, diagnostic tests, and clinical trial results for these cancers can drive large, sustained revenue opportunities and regulatory decisions that materially affect healthcare and biotech company valuations.
PD-L1 medical
"driver-negative tumors that express high levels of PD-L1 (tumor proportion score ≥50%)"
PD-L1 is a protein found on the surface of some cells that acts like a stop sign for the immune system, telling certain immune cells to back off. It matters to investors because many cancer drugs and diagnostic tests target or measure PD-L1 to unlock immune responses or predict which patients will benefit, affecting clinical success, regulatory approval, and potential sales in the oncology market.
Whole Exome Sequencing (WES) medical
"utilize Whole Exome Sequencing (WES), Whole Transcriptome Sequencing (WTS), and clinical data"
Whole exome sequencing (WES) reads the portions of a person’s DNA that code for proteins — about the most critical pages in the body’s instruction manual. By focusing on these protein-making sections rather than the entire genome, WES helps identify changes that can cause disease, guide diagnosis, or point to targets for drugs. Investors care because WES can speed discovery, reduce clinical uncertainty, and create clearer paths to diagnostic tests and targeted treatments that drive commercial value.
Whole Transcriptome Sequencing (WTS) medical
"utilize Whole Exome Sequencing (WES), Whole Transcriptome Sequencing (WTS), and clinical data"
Whole transcriptome sequencing (WTS) is a lab method that reads all the RNA messages inside a cell or tissue to show which genes are turned on or off, similar to collecting every email in an office to understand what tasks are being done. For investors, WTS matters because it can reveal disease mechanisms, identify drug targets or biomarkers, and improve patient selection or diagnostic tests—information that can change the commercial potential of therapies and diagnostics.
machine learning technical
"The signature leverages machine learning to identify complex molecular signatures"
Machine learning is a set of computer programs that learn patterns from large amounts of data and improve their predictions or decisions over time, like a recipe that gets better each time it’s adjusted based on taste tests. For investors it matters because these systems can speed up analysis, spot trends or risks humans might miss, automate routine work, and potentially create competitive advantages or cost savings that affect a company’s performance.
companion diagnostic (CDx) regulatory
"WTS-based assay with FDA-approved companion diagnostic (CDx) indications for molecular profiling"
A companion diagnostic (CDx) is a medical test designed to identify which patients are likely to benefit from, or be harmed by, a specific drug or therapy—think of it as a key that shows which locks a particular medicine can open. For investors, a CDx matters because it shapes how many patients can use the drug, affects regulatory approval and reimbursement odds, and reduces commercial and clinical risk by targeting treatment to the right people.
immunotherapy medical
"first-line treatment options include immunotherapy alone or a combination of immunotherapy and chemotherapy"
Treatment that uses or enhances the body’s immune system to detect and fight disease, most often cancers or chronic infections; think of it as training or arming the body’s own soldiers to find and destroy targets. It matters to investors because successful immunotherapies can lead to high-value drug approvals, recurring revenue from long-term treatments, and changes in competitive dynamics, while failures or safety issues in clinical trials can materially affect company valuations.

Caris AI Insights are proprietary and only available to Caris Life Sciences customers 

IRVING, Texas, April 8, 2026 /PRNewswire/ -- Caris Life Sciences® (NASDAQ: CAI), a leading, patient-centric, next-generation AI TechBio company and precision medicine pioneer, today announced the launch of a groundbreaking AI-driven molecular insight for a subset of mono-immunotherapy eligible non-small cell lung cancer (NSCLC) patients. The NSCLC immunotherapy (IO) treatment selection signature was developed to determine which patients benefit from the addition of chemotherapy versus those who are harmed by the addition of chemotherapy.

Caris Life Sciences continues to advance precision oncology by integrating multimodal real-world datasets available with its proprietary CodeAI™ platform, enabling the creation of Caris AI Insights, which utilize Whole Exome Sequencing (WES), Whole Transcriptome Sequencing (WTS), and clinical data to generate greater biological understanding and more actionable insights for physicians and patients.

NSCLC is the most common type of lung cancer and remains a leading cause of cancer-related deaths worldwide. For patients with driver-negative tumors that express high levels of PD-L1 (tumor proportion score ≥50%), first-line treatment options include immunotherapy alone or, in cases where the disease is considered more aggressive, a combination of immunotherapy and chemotherapy. While adding chemotherapy can improve outcomes for some patients, it may reduce survival for others. Traditionally, these critical treatment decisions have relied on clinical factors and physician judgment rather than underlying tumor biology. This new AI-driven signature leverages WES and WTS to help guide more precise and individualized therapy decisions. Additionally, prognostic information is provided for patients, reinforcing the need for personalized treatment strategies.

Developed using Caris' large-scale clinico-genomic datasets, the signature leverages machine learning to identify complex molecular signatures associated with treatment response, moving beyond small panel biomarker tests. The model operates in two phases: first, it stratifies patients into higher- versus standard-risk groups; second, it predicts which patients may benefit from additional chemotherapy. This approach aims to reduce unnecessary chemotherapy exposure, improve treatment and inform more biologically guided therapy choices for NSCLC patients.

"Our new NSCLC IO signature represents an important step forward in personalizing NSCLC treatment," said David Spetzler, MS, PhD, MBA, Caris President. "Not subjecting patients to potentially harmful chemotherapy and related toxicity is life-changing for cancer patients and represents a significant improvement in patient care.  Providing physicians with this unique and proprietary molecular signature helps them make treatment decisions and is a core part of the Caris mission.  This is another example of whole exome and transcriptome sequencing providing clinically actionable results that smaller panels with only hundreds of genes can't provide."

Caris received FDA approval in November 2024 for MI Cancer Seek, a tissue-based assay that is the first and only simultaneous WES and WTS-based assay with FDA-approved companion diagnostic (CDx) indications for molecular profiling of solid tumors.
