Clinical & Regulatory
1 | Guardant Health, Inc. - Guardant Health Receives Regulatory Approval for Guardant360® CDx in Japan
The Japanese Ministry of HealthLabor and Welfare (MHLW) gave Guardant360 CDx regulatory approval for CGP in advanced solid tumors. The companion diagnostic was also approved to identify patients with MSI-High solid tumors or MSI-High CRC in order to assign treatments for Keytruda or Opdivo respectively. Guardant 360 CDx was already granted approval back in December 2021 to identify patients with NSCLC who may benefit from LUMAKRAS.
Insightec, a company that use slow-intensity focused ultrasound (LIFU) to treat and diagnose a range of diseases, received an FDA investigational device exemption (IDE) for the application of its Exablate Neuro System in liquid biopsy for the recurrence monitoring of patients with primary brain cancer. The Exablate Neuro System’s ultrasound transiently increases the permeability of the blood brain barrier, enabling the passage of biomarkers to allow noninvasive liquid biopsy of brain tumors. The same system also received an FDA IDE for applications in primary non-small cell lung cancer (NSCLC) that has metastasized in the brain in conjunction with standard-of-care Keytruda in addition to an FDA Breakthrough Device designation(BDD) for NSCLC treatment.
PetDx is collaborating with Fidu to offer Fidu’s veterinary tele-consultation service for general practice veterinarians using the OncoK9 multi-cancer early detection liquid biopsy test for dogs. The collaboration provides direct access to internal medicine and oncology consultation, which further adds to customer support services already offered by PetDx.

1 | Burning Rock Adds Validation Data as it Begins MRD and Early Detection Commercialization
Burning Rock Biotech is launching its first MRD detection assay, BrPROPHET, with plans to release a six-cancer early detection test shortly thereafter. The company has a pipeline of partner hospitals for implementing the six-cancer screening assays, but COVID-19restrictions are a hindrance to execution. The six-cancer assay will be initially launched as a central lab test, but commercialization is still a possibility. The PREVENT study, consisting of 10,000 patients, will be used to validate the tests. The PROMISE study, which aims to validate Burning Rock's nine-cancer detection product, has just finished its first readout; PROMISE results will be presented with ESMO later this year.
2 | Gene Solutions Makes Earlier Detection of Cancer A Possibility of the Future
Gene Solutions - Vietnam announced a point-of-care (POC) LBx assay for early cancer screening named SPOT-MAS (Screening for the Presence of Tumor by Methylation And Size).SPOT-MAS aims to be an affordable and easily deployable LBx solution for developing countries. Gene Solutions claims to currently hold 80% and 50% of market share in genetic testing for prenatal screening and oncology, respectively, in Vietnam.
Invitae announced full access to its Personalized Cancer Monitoring (PCM) platform to help detect MRDin patients with solid tumors. Invitae PCM is a pan-cancer tumor-informed liquid biopsy assay that uses NGS to analyze ctDNA in plasma, and validation studies have demonstrated greater than 99.9% sensitivity in detecting ctDNA at a 0.008%variant allele frequency. PCM uses tumor-normal whole exome sequencing results and Invitae’s proprietary algorithm to identify 18-50 tumor specific variants to include for the patient’s custom-designed ctDNA panel.

Clinical Trials & Study Results
Inivata's LUngcancer CIrculating tumor DNA (LUCID) study analyzes Inivata's RaDaR LBx test for patients with early-stage NSCLC. In recent published results from the study, RaDaR assays were used to analyze the blood from 88 patients in order to evaluate how ctDNA detected by the assays may relate to recurrence of cancer.The data showed that clinical recurrence of the primary tumor was detected ~212days after ctDNA detection. An additional highlight of the study showed how highly sensitive assays are needed for MRD detection for lung cancer patients, as for 30% of patients with detectable ctDNA, the VAF was less than 100 parts per million of ctDNA.
Geneplus-Beijing Co. (sponsor) and Eastern Hepatobiliary Surgery Hospital (collaborator) initiated a 300 person observational trial on December 20, 2021 for the analysis of ctDNA and peripheral blood mononuclear cell (PBMC) collected before and after the first cycle of immune checkpoint inhibitors (ICI) with an estimated completion date of April 2024. The study includes patients with Primary Liver Cancer, Hepatocellular Carcinoma, Intrahepatic Cholangiocarcinoma, and Combined Hepatocellular-cholangiocarcinoma and analyzes their blood samples for dynamic changes of bTMB (tumor mutational burden), ctDNA, the composition of immune cells, and the combined tumor markers AFP, DCP, and CA19-9.
3 | AssesSment of Early-detection basEd oNliquiD Biopsy in LYmphoid Malignancies (ASCEND-LYM)
ASCEND-LYM is an observational study seeking to build an early detection model for lymphoma based on cfDNA methylation and other unspecified biomarkers. Burning Rock Dx is a collaboration this study, which is expected to enroll around 490 participants and begin inMay 2022.
