The company is on track to submit Guardant360 to the FDA in the third quarter, but also expects to see pan-cancer reimbursement much sooner.

The company sold nearly twice as many tests as in Q2 last year, with clinical test revenue more than doubling and total revenue reaching $54 million for the quarter.

Biocartis' Idylla called some colorectal cancer samples negative that Sysmex Inostics's OncoBEAM called positive, but the clinical implications may be complex.

The firm believes that physicians can use information from the cell-free DNA analyzed by the assay to determine whether to use anti-EGFR drugs during treatment.

The firm claims that its liquid biopsy platform can identify mutations in patient samples at femtogram-level concentrations.

Cyclomics, a 2018 spinout from University Medical Center Utrecht, is testing its assay for treatment response and recurrence monitoring in head and neck cancer.

The firm has joined forces with AstraZeneca, the IASLC, and the Global Lung Cancer Coalition, with a goal to double five-year survival rates by 2025.
