Guardant Health Presents Data at DDW Virtual Meeting Highlighting its Early Cancer Detection Program

Studies feature the LUNAR-2 liquid biopsy and its potential to improve colorectal cancer screening rates

REDWOOD CITY, Calif., May 02, 2020 (GLOBE NEWSWIRE) -- Guardant Health, Inc. (Nasdaq: GH) presents new data at Digestive Disease Week (DDW) 2020 that highlights the performance of its LUNAR-2 assay and reinforces its potential to improve colorectal cancer (CRC) screening rates by offering a simpler blood test that overcomes barriers associated with current testing methods. The LUNAR-2 assay is currently being evaluated in a large-scale registrational trial to detect CRC in average-risk adults.

“Despite the recent challenges of the COVID-19 pandemic, the ability to hold scientific discussions on research of cancer and other diseases, even in a virtual capacity like this year’s DDW, is essential to ensure our collective fight against cancer continues to advance,” said Helmy Eltoukhy, PhD, co-founder and CEO. “This year, we are excited to have three poster presentations scheduled during the meeting, including one poster of distinction on the performance of our LUNAR-2 assay study.”

Presentations:

  • Abstract #Sa1651 and Poster of Distinction: Plasma based cell-free circulating tumor DNA (ctDNA) assessment for non-invasive detection of colorectal cancer (CRC).

    Summary: In a new cohort analysis of colonoscopy screened negative patients (n=185) the assay demonstrated improved specificity of 94% at a target specificity threshold of 90%. The specificity improvement also resulted in improved sensitivity for CRC detection over previously reported performance. Some of the increase in specificity may correspond to undiagnosed malignancies or adenomas in unscreened participants in the presumably healthy control group.
    Presentation timing: Saturday, May 2, 2020.

     
  • Abstract #Mo1617: Where are we today? Efforts to understand strategies and barriers to physician issuance of a recommendation for colorectal cancer screening: A systematic review.

    Summary: Systematic literature review shows that primary care physicians have a diversity of opinions on patient-level barriers to CRC screening and strategies that may be useful to overcome them. Rates of CRC screening may be improved with approaches that are more affordable and easier to complete, but may still require provider communication regarding the recommendation.
    Presentation timing: Monday, May 4, 2020.

     
  • Abstract #Tu1974: Evaluating the number needed to screen and the number needed to invite to screening for colorectal cancer as a quantitative measure of the clinical impact of diagnostic technologies.

    Summary: This study reports on the early development of a model to assess the number of patients needed to screen (NNTS) and number needed to invite to screen (NNTI) for a CRC screening test. The data show that a diagnostic with high sensitivity, but low compliance may have a higher NNTI value as compared to a diagnostic with comparable sensitivity but higher compliance. The findings suggest that a lower NNTI score is an impactful assessment metric which can describe the true benefit of screening for colorectal cancer where compliance remains a significant societal challenge.
    Presentation timing: Tuesday, May 5, 2020.

The data being presented lend further support for the company’s first indication in early cancer for the detection of colorectal cancer in asymptomatic individuals. The tumor biology is well captured by the company’s blood-based technology; low CRC screening compliance represents a clear unmet medical need (one-third of adults in the U.S. are not up-to-date with recommended screening1); and existing pathways are in place for both downstream intervention and reimbursement, making it easier to drive clinical use.
