NeXT Personal is purpose-built to accurately detect MRD in patient samples with low overall ctDNA, which is particularly important for cancers that have low shedding or low mutational burden, such as breast and prostate cancers, or soon after resection. NeXT Personal leverages many elements of the asserted patents, including the use of whole genome sequencing to identify up to 1,800 variants that are specific to a patient’s cancer, thereby achieving superior signal-to-noise in the detection of ctDNA in plasma samples. Personalis launched its ultra-sensitive MRD solution, NeXT Personal™, in late 2021. By 2013, when we first began filing the applications that led to the patents we are asserting against Foresight, Personalis had already received customer orders to sequence and analyze over 1,000 human genomes and had realized the power of utilizing whole genome sequencing alongside our advanced targeted sequencing methods,” said Personalis CEO, John West. “Personalis has been active in whole human genome sequencing from very early on.

Personalis is seeking both injunctive relief and monetary damages based upon Foresight’s infringement of these patents. Personalis’ patent portfolio protects its pioneering work in whole genome sequencing to identify mutations that indicate the continued presence or recurrence of cancer with part-per-million sensitivity. These patents are part of Personalis’ intellectual property portfolio in the field of whole genome-enabled, tumor-informed molecular residual disease (MRD) testing.
