MENLO PARK, Calif. & SAN FRANCISCO--(BUSINESS WIRE)--Nov 30, 2022--
Personalis, Inc. (Nasdaq: PSNL) today announced a collaboration with UC San Francisco (UCSF) that will deploy a personalized liquid biopsy-based research use only (RUO) assay for a study of patients with colorectal cancer. The research efforts will use Personalis’ NeXT Personal ™ assay to evaluate circulating tumor DNA (ctDNA)-based signatures associated with treatment response and adverse events in a cohort of late-stage colorectal cancer patients receiving capecitabine together with pembrolizumab and bevacizumab.
Colorectal cancer is among the top five most prevalent and deadly malignancies worldwide. The efficacy of combined targeted therapy approaches varies widely, reflecting the need for more sophisticated predictive measures. Typical ctDNA assays in use today lack sufficient sensitivity for detecting cfDNA-based biomarkers due to extensive disease heterogeneity, potentially low levels of signal from small metastases, and the wide range of mutational profiles relevant to different types of cancer.
“Assessment of early response and adaptive resistance both critically require a non-invasive liquid biopsy-based assay that can confidently detect changes in the abundance and mutational profile of cancer cells. Through serial monitoring of ctDNA, we will develop greater understanding of patient response to therapy and use these data to inform the development of signatures predictive of response,” said Lawrence Fong, MD, the Efim Guzik Distinguished Professor in Cancer Biology at UCSF and leader of the Cancer Immunotherapy Program.
“The increased sensitivity of NeXT Personal will make it possible to identify complete response/absence of disease and recurrence earlier than existing technologies. Further, by leveraging the plasma sampling in this cohort, we aim to determine optimal sample collection timing for early identification of complete response and demonstrate clinical utility. Additionally, we seek to demonstrate earlier detection of disease recurrence, providing support for future interventional studies that can use this information to make rapid changes to treatment,” said Richard Chen, MD, Chief Medical Officer and Senior Vice President of R&D at Personalis.
About NeXT Personal
NeXT Personal is a next-generation, tumor-informed liquid biopsy assay designed to detect and quantify MRD and recurrence in patients previously diagnosed with cancer. The assay is designed to deliver industry-leading MRD sensitivity down to the 1 part-per-million range, an approximately 10- to 100-fold improvement over other available technologies. It leverages whole genome sequencing of a patient’s tumor to identify up to 1,800 specially selected somatic variants that are subsequently used to create a personalized liquid biopsy panel for each patient. This may enable earlier detection across a broader variety of cancers and stages, including typically challenging early-stage, low mutational burden, and low-shedding cancers. NeXT Personal is also designed to simultaneously detect and quantify clinically relevant mutations in ctDNA that may be used in the future to help guide therapy when cancer is detected. These include known targetable cancer mutations, drug resistance mutations, and new variants that can emerge and change over time, especially under therapeutic pressure.
