Genetron Health Provides Update on HCCscreentm for Liver Cancer Early Screening in China

Genetron Holdings Limited ("Genetron Health" or the "Company", Nasdaq: GTH), a leading precision oncology platform company in China that specializes in offering molecular profiling tests, early cancer screening products and companion diagnostics development, today provided an update for HCCscreen^TM, its blood-based early screening test for hepatocellular carcinoma ("HCC"), in China.

Led by the Wuxi municipal government ("Wuxi") and administered by the National Cancer Center (NCC) in China, the "Liver Cancer Early Screening Comprehensive Prevention and Control Project" is a public health initiative (the "Project"). The goal of the Project is to increase the awareness of liver cancer early screening, and to become a pilot city model in China. For the Project, Wuxi has selected HCCscreen^TM for local residents who are high-risk individuals for HCC, and is committed to administering 150,000 tests over a period of three years. Wuxi had entered into a small-scale collaboration agreement with Genetron Health in 2019, and the Project represents an expanded collaboration between the parties. Wuxi is a city in the southern part of Jiangsu Province in eastern China with a population of over six million people, and has emerged as a biopharma innovation hub in recent years.

Separately, Genetron Health has formed a new operating center through a joint venture agreement with Wuxi, in which the parties will closely collaborate on advancing the liver cancer early screening market in China, through the adoption of HCCscreen^TM. Under this joint venture agreement, both parties will contribute capital, and Genetron Health will own 90% of the joint venture. In addition to the commitment of using HCCscreen^TM for its residents, Wuxi will also provide Genetron Health with other supportive measures including rental, R&D subsidies and tax benefits.

"We are thrilled about this strategic partnership with Wuxi. It represents a major milestone for HCCscreen^TM as it will be broadly used in a real-world setting, reflecting its clinical value that both the NCC and Wuxi recognized. Wuxi's investment and other supportive measures also highlight its commitment to advancing the liver cancer early screening in China," commented Sizhen Wang, Genetron Health's co-founder and CEO. "This partnership provides Genetron Health with near term revenue opportunities, as well as a cost-effective structure to build another world-class lab, manufacturing facility and an operating center for future developments. Beyond the financial benefits, the strategic value from this partnership is tremendous. It enables large-scale, real-world adoption of HCCscreen^TM, representing an important step for our early screening product development, as well as potentially serving as a pilot model as we navigate the broader commercialization and reimbursement roadmaps in the future. Overall, we expect this initiative to ultimately help drive faster adoption of early cancer detection products in China."

About HCCscreen^TM and Liver Cancer

In September 2020, Genetron Health received the U.S. Food and Drug Administration ("FDA")'s Breakthrough Device designation for HCCscreen^TM, and the product has been commercialized recently as a lab developed test ("LDT") in China.

Globally, liver cancer is the fourth most common cause of cancer-related death and the sixth in terms of incidence¹. China represents the largest market, accounting for almost half of the global incidences. New incidence in China was estimated to be around 393,000 per year, with 369,000 deaths². Market data by Frost and Sullivan estimated that as of 2019, among the 120 million high risk liver cancer population in China, around 74 million were HBV carriers.

Powered by Genetron Health's innovative and proprietary Mutation Capsule^TM technology, which enables detection of multiple methylation alterations in parallel with mutations in cell-free DNA from peripheral blood specimens, HCCscreen^TM is currently being tested in its ongoing prospective study with 4,500 HBsAg+ individuals in HCC. As of the date of this announcement, 2,000 patients have already completed the study, and preliminary data from 297 patients at one center has demonstrated over 92% sensitivity, 93% specificity, compared to 67% and 99%, respectively in the ultrasound plus alpha-fetoprotein (AFP) arm. HCCscreen^TM also achieved a 35% positive predictive value and 99.6% negative predictive value. Furthermore, stratifying by tumor sizes, of the 12 patients identified with HCC in the preliminary dataset, 10 patients had tumor sizes of less than 5 centimeters. Of these, seven patients had tumor sizes of less than 3 centimeters, and HCCscreentm successfully detected them all, indicating its ability in detecting early-stage HCC.

In August 2020, Genetron Health announced its participation in the launch of a major national research project for early screening of lung and digestive system cancers led by China's Ministry of Science and Technology. The project is designed to include a multi-center, prospective cohort study in lung cancer of 120,000 high-risk individuals in 20 provinces, as well as a cohort study in digestive system cancer of more than 100,000 patients in urban areas in China. Genetron Health is the only company in China involved in national key research and development projects for liver, lung and digestive cancer early screening.
