Highlights & Summary

August showcased new partnerships, CDx regulatory approvals, new clinical trials and study results in liquid biopsy.


Company Announcements & Product Launches

Of note in product launches and expansions this month, Predicine launched their CE-IVD LBx assay, PredicineCARE. This assay identifies over 150 genes to help with clinical trial pairings and therapeutic selection for patients. Guardant Health expanded the utility of their Guardant Reveal LBx test to apply to the detection of recurrent early-stage breast and lung cancers in addition to colorectal cancer (CRC). John Hopkins University developed a Liquid Biopsy for Breast Cancer Methylation (LBx-BCM) assay that utilizes Cepheid’s GeneXpert platform to allow for more decentralized breast cancer testing. Currently, patients undergoing chemotherapy for breast cancer will not know their therapeutic response until imaging is undergone 2 or more months later; LBx-BCM can detect tumor DNA within just hours of application.

Clinical & Regulatory

In clinical and regulatory developments this month, Guardant Health’s Guardant360 CDx received an FDA approval as a companion diagnostic for NSCLC patients who may benefit from Astrazeneca and Daiichi Sankyo’s drug ENHERTU — a HER2-directed antibody drug conjugate. Guardant360 CDx can identify patients with HER2 mutations, helping inform treatment eligibility. Outside of NSCLC, Guardant Health was in the news this month for receiving Medicare coverage for Guardant Reveal — a molecular residual disease (MRD) test. This test was the first blood based MRD test available for CRC patients. Now, for Medicare patients in the United States with stage II or stage III CRC, this approval may positively impact their accessibility to this test.

Clinical Trials & Study Results

Foundation Medicine, Flatiron Health, and Genentech announced results from a study that compared the ability of FoundationOne CDx and FoundationOne Liquid CDx to detect actionable biomarkers in patients with advanced NSCLC. Genetron Health launched a trial in collaboration with Piedmont Transplant Institute to assess performance of Genetron’s novel HCC (hepatocellular carcinoma) liquid biopsy biomarkers assay for early detection. Similarly, Exact Sciences collaborates with West German Study Group to conduct a study on HR+, HER2- early breast cancer patients to assess Exact’s tumor-informed ctDNA liquid biopsy test for detecting minimal residual disease (MRD) and collecting long-term follow up and outcome data. InterVenn Biosciences also announced the start of enrollment in its colonoscopy study intended to validate their platform for detecting early colorectal cancers and precancerous adenomas from blood.
