Genomic Health Presents Positive Proof-of-Concept Data for Bladder Cancer Liquid Biopsy Test

REDWOOD CITY, Calif., June 16, 2015 /PRNewswire/ -- Genomic Health, Inc. (Nasdaq: GHDX) today announced positive results from a liquid biopsy proof-of-concept study demonstrating its ability to more conveniently detect disease recurrence with a level of accuracy comparable to cystoscopy, an invasive procedure for surveillance of early-stage bladder cancer. These results support Genomic Health's development of a urine test that may offer physicians and patients a non-invasive alternative for physicians to monitor patients' bladder cancer.

"A liquid biopsy test has the potential to improve patient compliance during a surveillance protocol while monitoring for bladder cancer recurrence for patients with non-muscle invasive disease," said Neal Shore, M.D., medical director, Carolina Urologic Research Center. "This study contributes to the development of a urine test to optimize successful surveillance strategies and enhance the efficiency of care for bladder cancer patients." 

Early-stage bladder cancer is estimated to recur in 10 to 15 percent of patients in the first year and in more than half of patients over time. Currently, bladder cancer surveillance is repeated at frequent intervals via a cystoscopy, a procedure that inserts an instrument equipped with a camera and light to look at the inside of the bladder.

By measuring multiple target tumor-specific biomarkers using Genomic Health's liquid biopsy platform, the study demonstrated a negative predictive value for high-risk recurrence at that time of 95 percent, which means that if a patient's results are negative, there is a 95 percent chance that he or she has not had a recurrence at that time. These new results suggest that use of this urine-based liquid biopsy test would be expected to optimize surveillance and reduce the number of invasive procedures.

"This study represents one of many efforts in our robust research and development program to deliver multiple liquid-based tests for various tumor types beginning in 2016," said Ellen Beasley, Ph.D., senior vice president, Research and Development, Genomic Health. "As we continue to advance our liquid biopsy pipeline, we are moving forward with finalizing the development of a non-invasive, urine-based bladder cancer tracking test with a goal of initiating clinical validation later this year." 

The study, presented at the American Association for Cancer Research (AACR) Precision Medicine Meeting, included data from 74 patients across 14 sites, and was co-led by Associated Medical Professionals of New York, Carolina Urologic Research Center, Genomic Health, NorthShore University HealthSystem and Vanderbilt University Medical Center.
