Partnership marks significant milestone for Natera in monetizing its Signatera MRD test and for BGI Genomics a strong endorsement of its DNBseq™ technology platform by a leader in cell-free DNA genetic testing

SAN CARLOS, Calif. and SHENZHEN, China — Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA genetic testing, and BGI Genomics Co., Ltd., (300676.SZ), the largest cell-free DNA clinical testing laboratory in China and one of the world’s leading genomics companies, today announced a $50 million partnership to commercialize Natera’s Signatera™ MRD test in China, and to develop reproductive health tests in select markets on BGI’s sequencing instruments using the DNBseq™ NGS technology platform.

The Natera Signatera MRD and molecular monitoring test will be offered in China, first through specialty hospital networks and then more broadly, once Natera and BGI Genomics gain China’s regulatory approval for use of the Signatera test on the DNBseq™ technology platform. DNBseq™ is the market name of BGI’s proprietary sequencing technology, which supports its portfolio of next-generation sequencing platforms. BGI Genomics’ genetic testing leadership position in China, where it performs over 1 million cell-free DNA tests annually,1 will accelerate Natera’s entry into this large and growing oncology market.

Cancer is the leading cause of death in China with roughly 4.3 million new cancer cases and 2.8 million deaths reported annually.2 The molecular diagnostics market in China is a rapidly growing multi-billion-dollar market, driven largely by the rising incidence of cancer and infectious diseases.3

“Natera shares our core vision of improving human health by offering innovative genetic testing solutions that allow for earlier and more effective diagnosis of disease,” said Yin Ye, CEO at BGI Genomics. “Natera’s decision to launch its Signatera test into China on BGI’s DNBseq™ technology platform is a testament to both the quality and versatility of our technology. We look forward to working together with Natera for the general benefit of people worldwide and to expanding access to the DNBseq™ technology platform to other customers globally.”

“We are very impressed with BGI’s pace of innovation, its people, and its scale of operations in China,” said Steve Chapman, CEO at Natera. “BGI is a recognized world leader in next-generation sequencing and, we believe, the most qualified laboratory partner for us in China. This deal continues Natera’s commercialization success in oncology, augmenting over 30 pharmaceutical trials currently underway, and is a strong endorsement of Natera’s leading technology in oncology and reproductive health.”

“We are excited for the opportunity to partner with an innovative leader like BGI to commercialize Signatera in China and expand the reach of Natera’s reproductive health technology in select markets, and we believe BGI has the capability to substantially reduce costs for offering our technology,” said John Fesko, Sr. Vice President of Business Development at Natera. “This deal complements our strategic partnerships with existing sequencing providers and does not alter our plans with them. This exciting alliance is key to our vision of being the application layer for genetic testing worldwide.”

About DNBseq™ Technology
DNBseq™ technology is a proprietary sequencing technology originally developed by Silicon Valley-based Complete Genomics, which was acquired by BGI in 2013.

DNBseq™ sequencing technology is powered by PCR-free Rolling Circle Replication, combinatorial Probe-Anchor Synthesis (cPAS) and DNA Nanoballs (DNB) technology. The cPAS chemistry works by linking a fluorescent probe to a DNA anchor on the DNB, followed by high-resolution digital imaging. This combination of linear amplification and DNB technology reduces the error rate while enhancing the signal. In addition, the size of the DNB is controlled in such a way that only one DNB is bound per active site in the flow cell. This patterned array technology not only provides sequencing accuracy, but it also increases the chip utilization and sample density. Unlike PCR amplification, amplification errors arising from Rolling Circle Amplification do not accumulate exponentially, allowing DNBseq™ platforms to deliver a high level of data clarity.

NGS data from DNBseq™ technology is documented by a growing body of studies, with over 100 peer-reviewed publications to date. BGI has also published pilot data from its sequencing platforms running on DNBseq™ technology, including samples processed for human whole genome sequencing from the UK Biobank as part of a proof of concept study.

About Signatera™
Signatera is the first circulating tumor DNA (ctDNA) test custom-built for molecular treatment monitoring and molecular residual disease (MRD) assessment. The test is available for research use only until its clinical launch planned for Q2 2019. The Signatera methodology differs from currently available liquid biopsy tests, which test for a fixed panel of therapeutically relevant genes. Signatera provides each individual with a customized blood test tailored to match the clonal mutations found in that individual’s tumor tissue. This maximizes accuracy for detecting the presence or absence of MRD in a blood sample, even at levels down to a single mutant molecule in a tube of blood. Signatera RUO also allows researchers to track additional mutations of interest, up to several hundred mutations, for clinical studies.

The body of evidence on the utility of Signatera is growing:

• A 2017 study demonstrated the Signatera RUO method’s ability to detect MRD, 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) with 93 percent sensitivity and zero false positives.4
• Data presented at the European Society for Medical Oncology 2018 Congress showed successful results from bladder and colorectal cancer studies, including median detection points of MRD that were 3.3 and 7.9 months, respectively, ahead of clinical relapse detection.5,6
• In two studies presented at the 2018 San Antonio Breast Cancer Symposium, Signatera RUO was able to detect MRD up to two years prior to clinical relapse and predict treatment response in a cross-section of breast cancer patients, including those who were HER-2 positive, hormone receptor-positive, and triple negative.7,8

Based on numerous studies across multiple cancer types, a positive Signatera RUO result without further treatment has predicted clinical relapse nearly 100 percent of the time.4-8
