Caris Life Sciences Identifies TET2 as a Key Biomarker for Immunotherapy Success

Introduction

Caris Life Sciences®, a pioneering company in precision medicine and artificial intelligence technologies, has made substantial strides in oncology research. The company recently announced groundbreaking findings that could reshape the landscape of immunotherapy for patients battling solid tumors.

New Research Findings

On October 29, 2025, Caris Life Sciences disclosed new collaborative research from the James P. Allison Institute at The University of Texas MD Anderson Cancer Center, focused on TET2 clonal hematopoiesis (CH) and its effectiveness as a biomarker in immunotherapy (specifically immune checkpoint inhibitor or ICI therapy). The study, led by Dr. Padmanee Sharma, aimed to delve deep into the interaction between immune responses and TET2 mutations in cancer treatment.

The research has confirmed that TET2 mutations in clonal hematopoiesis significantly enhance the immune checkpoint therapy response. The scientists utilized laboratory models to discover how TET2 mutations modify immune dynamics within solid tumor environments. The ultimate goal was to emphasize the importance of TET2-CH in predicting patient outcomes regarding immunotherapy.

Key Clinical Insights

To establish the clinical relevance of their laboratory findings, the researchers tapped into Caris Life Sciences' expansive clinico-genomic database, scrutinizing treatment outcomes from nearly 36,000 patients with non-small cell lung cancer (NSCLC) alongside over 25,000 colorectal cancer patients. This dual approach revealed significant evidence depicting TET2-CH as a promising biomarker, paving the way for more personalized treatment strategies in immunotherapy.

Such major findings bridge a critical gap in therapy selections, giving hope that clonal hematopoiesis can serve as an indicator for therapy success. Dr. Milan Radovich, Chief Scientific Officer at Caris, noted, “We are only scratching the surface on the potential applications of CH.” He stressed the possible utilization of these findings to enhance patient outcomes significantly.

Future Implications and Research Directions

The results from this study encourage further exploration of the role of clonal hematopoiesis within cancer immunology. As Dr. Sharma pointed out, the findings indicate that TET2 mutations could identify patients expected to respond positively to immunotherapies. This insight represents an exciting new avenue for treatment choices, enhancing the potential for improved patient management.
