Caris Life Sciences Publishes Study Validating Caris AI Insights for Temozolomide Benefit in Glioblastoma Patients
Caris AI Insights are proprietary and only available to
GBM is the most common and aggressive brain cancer, with patients typically surviving around 12 months despite treatment. Current treatments include surgery to remove the tumor, radiation and chemotherapy with temozolomide (TMZ). Unfortunately, nearly half of GBM patients do not respond to TMZ and many develop resistance that leads to recurrence. Determining whether TMZ will benefit the patient is a critical step in treatment and provides insight for developing new therapies for patients who do not respond favorably.
The novel signature, developed by Caris using multimodal molecular and clinical data, is an AI-derived model designed to infer O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status from NGS data. MGMT promoter methylation is an established biomarker associated with response to TMZ therapy in GBM patients that is commonly assessed using pyrosequencing. In the peer-reviewed validation study, the signature demonstrated high concordance with pyrosequencing-based MGMT assessment and improved discrimination of overall survival outcomes across MGMT-defined patient subgroups, while also addressing variability in MGMT classification associated with traditional testing methods. These findings show that Caris' proprietary AI signature can complement existing testing approaches and provide additional clinical insight for isocitrate dehydrogenase (IDH)-wild type GBM patients treated with TMZ.
"The Caris AI Insights signature for GBM showcases Caris' advanced AI capabilities in our pursuit of improving cancer patient outcomes," said Caris President
The model was trained to predict MGMT promoter methylation status, as measured by a pyrosequencing assay, using tumor profiling data from the MI Cancer Seek NGS assay, which also has FDA-approved CDx indications. As reported in the study, the signature was developed using a clinico-genomic dataset of 5,841 patients and further evaluated in a prospective cohort of more than 3,400 cases. The model stratified patients into distinct survival groups based on the signature score, with higher scores associated with significantly longer overall survival in TMZ-treated patients.
