AnPac Bio Study Shows Strong Correlation between CDA Score and Risk of Cancer and Diseases

Large Population Screening Study Reached Key Milestone with Over 2,000 Confirmed Cases

PHILADELPHIA, Oct. 04, 2021 (GLOBE NEWSWIRE) — AnPac Bio-Medical Science Co., Ltd. (Nasdaq:ANPC, “AnPac Bio,” the “Company” or “we”), a biotechnology company with operations in China and the United States focused on early cancer screening and detection, announced today it has achieved a significant milestone and positive result in its general population cancer risk assessment tests and subsequent follow-up study on enrolled individuals whom obtained further check-ups and diagnosis at healthcare providers using their cancer and disease diagnostic tools. As of September 30, 2021, healthcare providers have confirmed 2,067 cancer, pre-cancer, and disease cases, which includes 22 identified types of cancer, 25 identified types of pre-cancer, and multiple other related diseases. An initial analysis showed that confirmed cases are strongly correlated to CDA test score, confirming that the CDA test is an effective method to initially screen the population for risks associated with cancer.

AnPac Bio’s follow-up study involved (a) enrolling high, medium, and low risk groups of individuals based on their CDA test scores following CDA testing of a large, asymptomatic population, (b) recommending enrolled individuals to obtain follow-up check-ups at healthcare providers, (c) following up with enrolled individuals via phone interviews, and (d) analyzing interview results and data. As of September 30, 2021, 14,806 individuals in the high, medium and low risk groups were contacted and interviewed, and 2,067 individuals were confirmed as cancer, pre-cancer or other disease patients. Based on an initial analysis of the most recent follow-up data and results, CDA technology is an effective initial screening tool for asymptomatic general population for multiple cancer types, pre-cancer types and other related diseases. The confirmed cancer and pre-cancer cases detected 22 types of cancer and 25 types of pre-cancer, including esophageal cancer and thyroid cancers that currently lack effective biomarkers for early screening and detection.

Distribution of high, medium, and low risk groups based on CDA tests
Clinical Status High and Medium Risk Group Low Risk Group
Confirmed cancer cases 99.1% 0.9%
Pre-cancer cases 93.3% 6.7%
Confirmed other disease cases 95.0% 5.0%

The top five confirmed cancer types and pre-cancer types are as follows:

Types of Cancer  Number of patients
   
Colorectal cancer 40
   
Lung cancer 32
   
Gastric cancer 27
   
Prostate cancer 24
   
Breast cancer 23
   
Types of pre-cancer Number of patients
   
Thyroid nodule/benign tumor 230
   
Pulmonary nodule 179
   
Lesions of the breast/                                 
Hyperplasia of breast glands
135
   
Hysteromyoma 93
   
Gastroduodenal diseases 83

The above data demonstrates that CDA technology is also very effective in finding pre-cancer diseases as confirmed pre-cancer cases are much higher than those of confirmed cancer cases, which is very attractive and meaningful for cancer prevention. However, the confirmed cases are highly likely to be under-reported because (a) only cases from individuals that we were able to successfully contact are recorded, (b) some enrolled subjects did not give full final diagnosis results when contacted, and (c) as an on-going follow-up study, more confirmed cases will likely be developed and recorded over time.

Developing a viable pre-cancer and early-stage cancer screening technology is critical to detect cancer early and to save patient lives. However, its development and progress has been relatively slow, despite decades of heavy investments and efforts by leading scientists and research groups. One of the key factors has been the lack of leading detection experts to develop sensitive technologies for low level signal collection and processing. AnPac Bio has built a unique team of physicists, and experts with extensive experience from semiconductor and AI-based computational analysis to build the unique CDA technology platform.

Over the past 12 years, AnPac Bio’s team has innovated and developed biophysics-based detection technology, in which biophysical properties of blood are detected and analyzed for early-stage cancer screening and detection. The Company has been a staunch champion of the concept of multi-cancer detection through developing its CDA technology. The measurement of biophysical properties for cancer detection can detect multiple cancer types earlier, more cost effectively, with higher sensitivity and specificity, and through relatively simple sample requirements and test procedures. These features make AnPac Bio’s CDA technology perfectly suited for screening general population for cancer affordably.     

Dr. Chris Yu, CEO and Chairman of AnPac Bio commented: “We are very pleased to reach the milestone of confirming over 2,000 cases and to achieve significant validation of CDA technology for general population cancer and pre-cancer risk assessment. This is truly a breakthrough technology in catching multiple cancer and pre-cancer types earlier to prevent cancer and provide better patient outcomes. We are very proud of our contributions to the battle against cancer and we are contributing to save lives now. We are already making a significant impact in the fight again cancer through our innovative ideas (multi-cancer detection), technology development and finding potential cancer and pre-cancer earlier on a daily basis. We believe our CDA technology’s results speak for themselves and expect that public health agencies and organizations seeking the most promising tools for detecting cancer and pre-cancer earlier will look closely at AnPac Bio.”
