Designation represents Genetron Health’s first step to potentially expand the geographical reach of HCCscreen™
BEIJING and GAITHERSBURG, Md., Sept. 30, 2020 (GLOBE NEWSWIRE) -- 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 announced that its blood-based next-generation sequencing (NGS) test, HCCscreenTM, has been granted Breakthrough Device designation by the U.S. Food and Drug Administration (FDA). Based on the correspondence with Center for Devices and Radiological Health (CDRH) of the FDA, HCCscreenTM is intended for early detection of hepatocellular carcinoma in individuals who are designated to be at high-risk for HCC due to chronic HBV infection and/or liver cirrhosis.
Under the FDA’s Breakthrough Devices Program, the Breakthrough Device designation is granted for products that have the potential to offer more effective diagnosis of life-threatening diseases with an unmet medical need. The program is designed to speed up development, assessment and review processes, in order to provide patients with quicker access to those devices. Genetron Health’s HCCscreenTM was granted based on its superior clinical performance over the current standard of care (i.e., ultrasound plus alpha-fetoprotein (AFP)) in a prospective clinical study. With this designation, the Company will have an opportunity to interact with the FDA's experts to efficiently address topics through the pre-submission process, so as to receive feedback from the FDA and identify areas of agreement in a timely way. It also allows priority review upon premarket approval (PMA) submission, and Medicare coverage by the CMS (Center for Medicare and Medicaid Services) upon formal approval.
Genetron Health intends to develop HCCscreenTM as an NGS-based product in the US. The company is also building a lab in Maryland, which it intends to seek CLIA certification, to serve global pharmaceutical companies on R&D and commercialization. In China, HCCscreenTM has recently been commercialized as a lab developed test (LDT). The Company has five laboratories in China, of which the Beijing lab is one of the few domestic labs that are both CAP and CLIA certified.
HCCscreenTM is powered by Genetron Health’s innovative and proprietary Mutation CapsuleTM technology, which enables detection of multiple methylation alterations in parallel with mutations in cell-free DNA from peripheral blood specimens. Currently, HCCscreenTM is being tested in its ongoing prospective study with 4,500 HBsAg+ individuals. 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 and 93% specificity, compared to 67% and 99%, respectively in the ultrasound + AFP arm. HCCscreenTM 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, ten patients had tumor sizes of less than five centimeters, indicating HCCscreenTM’s detection ability in early-stage HCCs. The company expects to announce the full data set from all 2,000 patients in the first half of 2021.
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. In the US, liver cancer is the fifth leading cause of cancer death in all ages, and it is increasing by 2% to 3% annually. New liver cancer cases in US was estimated to be 42,810 in 2020, with 30,160 deaths3. HCC represents the major histological type of liver cancer, accounting for 85–90% of cases4. Moreover, there is no effective therapy for advanced stage HCC. Previous estimates showed that the one-year survival for HCC in the United States is less than 50%, while the five-year survival is 10%5. Early detection of HCC is an unmet medical need. Current guidelines recommend at-risk patients undergo testing every six months using ultrasound with or without the AFP blood test6.
“We are very pleased with the FDA's recognition of HCCscreenTM’s potential as a more effective test for early detection of hepatocellular carcinoma. This designation also represents a significant milestone for our plan to expand HCCscreenTM’s geographical reach. Hepatocellular carcinoma is one of the leading causes of cancer deaths globally, and an accurate, easy to use, blood-based early screening test would offer tremendous clinical value,” commented Sizhen Wang, Genetron Health’s co-founder and CEO. “Our HCCscreenTM asset has shown promising preliminary data in all key metrics including sensitivity, specificity, and positive predictive value. Notably, most of the confirmed HCC patients in the study had tumor sizes below five centimeters. This level of performance is highly encouraging as detecting tumor presence while they are small allows effective early interventions, which could lead to better outcomes. Our goal is to continue to make clinical progress in order to potentially bring HCCscreenTM to more patients globally. This FDA designation represents the first, yet an important step, in our effort to achieve that goal.”
