Technology
Cvergenx has developed a genomics-based approach that provides radiation oncologists with the first opportunity to biologically optimize and personalize radiation therapy dose for each individual patient.
The Precision RT Dose platform (pRTD) utilizes tumor-specific genomic data to quantify the personalized biological effect of a given dose of radiation therapy. It integrates a gene expression signature of tumor radiosensitivity (RSI), into the classic linear-quadratic model to quantify the genomic-adjusted radiation dose (GARD), which represents a predicted personalized biologic radiation effect for each patient’s tumor. Radiation oncologists can utilize GARD to optimize the therapeutic index of a radiation therapy plan to maximize the biological effect of RT on a tumor while respecting normal tissue dose constraints, and safety guidelines, providing the first opportunity for genomic-based radiation oncology.
We are now in the process of demonstrating how patients can benefit by integrating biological information into radiotherapy treatment plans to optimize dose on an individualized basis.
The sequencing of the human genome has revealed that cancer is not a single disease but multiple diseases that are inherently different at the genetic level. This realization has led to the era of precision medicine. While genomics has substantially improved the practice of medical oncology, radiation therapy is still reliant upon a one-size fits all approach, where all patients receive uniform doses of radiotherapy. The pGRT platform provides the first clinically-validated approach to genomic-based radiation therapy — a potentially curative treatment that is currently received by up to 60% of all newly diagnosed cancer patients.
