Natera and Fox Chase Cancer Center to Collaborate on Kidney Cancer Study

SAN CARLOS, Calif., Aug. 15, 2018 /PRNewswire/ — Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, has partnered with Fox Chase Cancer Center, one of the leading cancer centers in the United States, to assess the company’s Signatera™ (Research-Use Only) customized circulating tumor DNA (ctDNA) assay for recurrence monitoring of kidney cancer.

The study will analyze biological specimens collected and banked from 49 patients diagnosed with kidney cancer—including a group whose cancer recurred and a group that did not recur after three years or more. The study will use Natera’s proprietary customized assay and next-generation sequencing (NGS)-based technology to determine whether Signatera (RUO) can be used to distinguish between the recurring and non-recurring kidney cancer cases. The study will be led by Philip Abbosh, M.D., Ph.D., assistant professor, Molecular Therapeutics Program, Fox Chase Cancer Center.

"There is a paucity of data for circulating tumor DNA in kidney cancer. This research study will explore a novel approach for disease recurrence and treatment response monitoring in kidney cancer, since existing methods have limitations with sensitivity and specificity," Dr. Abbosh said. "Determining the relationship between kidney cancer genetic profiles and prognosis including recurrence using the Signatera assay has great potential to improve patient care by detecting cancer recurrence earlier, assisting adjuvant therapy decision-making, determining treatment effects, and assessing the need for intervention during follow-up."

Kidney cancer is among the 10 most common cancers in both men and women.1 According to the American Cancer Society, more than 60,000 new cases of kidney cancer will be diagnosed this year, and nearly 15,000 people will die from this disease.1

C. Jimmy Lin, M.D., Ph.D., M.H.S., Natera’s Chief Scientific Officer, Oncology, said this kidney cancer study joins a growing number of research collaborations the company has established in the past 18 months involving a variety of cancer types, including breast, bladder, colorectal, and lung cancers. "We look forward to working with Fox Chase Cancer Center," Dr. Lin said. "We expect that this study, along with our ongoing research efforts in other cancer types, will help us move toward clinically validating Signatera, with the goal of enabling more precise monitoring, better determination of prognosis, and individualized treatment of disease."

About Signatera 
Signatera (RUO) is the first ctDNA assay custom-built for treatment monitoring and minimal residual disease assessment. The Signatera (RUO) methodology differs from currently available liquid biopsy assays, which test for a panel of genes independent of an individual’s tumor. In contrast, Signatera (RUO) provides each patient with a customized blood test tailored to match the mutations found in that individual’s tumor tissue, which maximizes sensitivity and specificity. Signatera (RUO) also allows researchers to track additional mutations of interest, up to several hundred mutations.

A recent study demonstrated the Signatera (RUO) method’s ability to detect residual disease, measure treatment response, and identify recurrence up to 11 months earlier than the standard of care for early stage non-small cell lung cancer (NSCLC).2 Additional research presented at the 2018 American Association for Cancer Research meeting showed successful results from bladder and colorectal cancer studies, including median detection points of ctDNA that were 4.3 and 7.9 months ahead of clinical relapse detection, respectively.3,4

About Fox Chase Cancer Center
The Hospital of Fox Chase Cancer Center and its affiliates (collectively "Fox Chase Cancer Center"), a member of the Temple University Health System, is one of the leading cancer research and treatment centers in the United States. Founded in 1904 in Philadelphia as one of the nation’s first cancer hospitals, Fox Chase was also among the first institutions to be designated a National Cancer Institute Comprehensive Cancer Center in 1974. Fox Chase researchers have won the highest awards in their fields, including two Nobel Prizes. Fox Chase physicians are also routinely recognized in national rankings, and the Center’s nursing program has received the Magnet recognition for excellence four consecutive times. Today, Fox Chase conducts a broad array of nationally competitive basic, translational, and clinical research, with special programs in cancer prevention, detection, survivorship and community outreach.
