GOZILA Study Published in Nature Medicine Shows Patients With Advanced Cancer Who Receive Liquid Biopsy-Guided Treatment Using Guardant360 CDx Survive Twice as Long

  • In study of more than 4,000 patients with advanced gastrointestinal tumors, 24% were able to receive targeted treatment based on genomic profiling results from blood test

  • Study findings are expected to advance liquid biopsy-guided cancer treatment to help improve outcomes for more patients

PALO ALTO, Calif., September 18, 2024--(BUSINESS WIRE)--Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced the peer-reviewed journal Nature Medicine published results from the SCRUM-Japan GOZILA study confirming that selecting targeted therapy on the basis of Guardant360? CDx liquid biopsy results may significantly extend survival for patients with advanced cancer.

The study, led by a research group out of National Cancer Center Hospital East in Kashiwa, Japan, investigated the effects of personalized treatment based on results of the Guardant360 CDx test in 4,037 patients with advanced cancer. The results showed that 24% of participants were able to receive targeted treatment tailored to them based on comprehensive genomic profiling results from the test, which analyzes 74 cancer-related genes. The patients who received targeted treatment guided by liquid biopsy results lived approximately twice as long as those who did not.

"Compared to conventional tissue biopsies, liquid biopsies have several advantages: they are less invasive for patients, allow for repeated testing, and can simultaneously examine cancer characteristics from various parts of the body. However, until now, it was unclear whether treatment selection using liquid biopsies actually helped improve patient outcomes," said Yoshiaki Nakamura, M.D., Ph.D., chief, International Research Promotion Office, Department of Gastroenterology and Gastrointestinal Oncology at National Cancer Center Hospital East in Kashiwa, Japan, and a co-lead author of the study. "The GOZILA study is the first to demonstrate the survival-extending effect of liquid biopsy-based personalized cancer treatment on a large scale across various cancers. The results of this study have the potential to bring about a paradigm shift in cancer treatment."

Selecting therapies for patients based on the liquid biopsy results enabled study investigators to identify targeted treatment options they could not discern using traditional methods. The researchers then followed the progress of treated patients and analyzed their treatment response and survival time. Patients who received targeted therapy had a median survival of 18.6 months compared to 9.9 months for those who did not.
