Science

Cancer screening today is inconvenient and invasive: Two leading cancers, colon and breast, use screening technologies developed 50 years ago, leading The New York Times to label the colonoscopy, “the dreaded turning-50 test.”¹ As a result, these dated and uncomfortable cancer-screening technologies are on the decline.² ³

Yet, screening is critical. Cancer patients have a 90% chance of survival if cancer is detected at stage I versus only a 5% chance at stage IV4.

Over the past 10 years, the team of scientists at Laboratory for Advanced Medicine have used artificial intelligence and machine learning to identify unique and proprietary DNA signatures that predict the presence of cancer as early as stage I.

We are focused on developing simple, accurate, and customer-friendly tests that detect cancer early—all from a simple blood draw.

DNA methylation markers for diagnosis and prognosis of common cancers

After evaluating the DNA methylation profiles for normal tissue and tumors from four common cancers (lung, breast, colon, and liver), the authors differentiated cancerous tissue from normal tissue with >95% accuracy. This demonstrates that methylation biomarkers can be used for the molecular characterization, diagnosis, and prognosis of cancer.

Identifying medical diagnoses and treatable diseases by image-based deep learning

With a diagnostic tool based on an AI-system that utilizes transfer-learning techniques, the authors accurately classified images for macular degeneration and diabetic retinopathy and distinguished bacterial and viral pneumonia on chest x-rays. This diagnostic tool has incredible potential for more applications.

Circulating tumor DNA methylation markers for diagnosis and prognosis of hepatocellular carcinoma

In comparing hepatocellular carcinoma (HCC) tissue and normal blood leukocytes, the authors found a high correlation between the methylation profiles of HCC tumor DNA and matched plasma circulating tumor DNA (ctDNA). The authors’ findings demonstrate an effective, blood-based method for the diagnosis and prognosis of HCC.

Clinical Trials

Laboratory for Advanced Medicine Clinical Research Programs

To gain regulatory approval to support our cancer test accuracy claims, Laboratory for Advanced Medicine is conducting extensive clinical study programs in the United States and China. Through collaborations with leading scientists, physicians, research institutions, and regulators worldwide, we aim to validate our products and provide the most effective diagnostic technologies to patients and doctors.

Current Studies

United States

Clinical Trial for the Liver Cancer Test (CLiMB)
CLiMB is a clinical trial to detect liver cancer through the quantification of cfDNA methylation in blood samples.

  • The trial is designed to evaluate the performance of our liver cancer test versus the standard of care today—an ultrasound test.
  • The study will enroll approximately 1,600 participants ages 21 to 84 years with a diagnosis of liver cirrhosis and hepatitis and who are currently recommended for liver cancer screening every six months by ultrasound. This study is expected to be completed in 2020.

China

  • The trial is designed to evaluate the performance of our liver cancer test against the performance of ultrasound and alpha-fetoprotein (AFP) test.
  • The study will enroll approximately 1,000 participants with a diagnosis of primarily hepatitis. This study is expected to be completed by the first half of 2020.

Intellectual Property

LAM has patented its cfDNA methylation markers since 2014. The patents cover methylation markers, method of using methylation for early cancer detection, and our AI technology.
