Exact Sciences Corp. demonstrated a significant increase in accuracy with the latest version of its Cologuard test for colorectal cancer in its pivotal BLUE-C study. Top-line results released this week showed that the next-generation test exceeded the specificity and sensitivity seen in the DEEP-C study that underpinned U.S. FDA approval of the commercially available version of Cologuard, a stool-based assay.
TG Immunopharma Co. Ltd. has announced clearance by the FDA for a clinical trial of TGI-6, a bispecific antibody targeting unique tumor-associated antigens (TAA) and CD3 molecules simultaneously, for solid tumors.
Colorectal cancer (CRC) is one of the digestive tract cancers with the highest prevalence. Cancer immunotherapy for CRC brings substantial benefit to patients, but the development of resistance mechanisms and relapsing processes along with immune escape call for new treatment options.
Interactions between the gut microbiome and immune system influence cancer immune surveillance, though the mechanism through which these gut-primed immune cells regulate peripheral antitumor immune response is not well understood. Now, two recent studies in Science and Science Immunology using mouse models and human tissue samples have highlighted a group of intestinal T cells with the gut-homing α4β7 integrin receptors that play a critical role in mediating response to immune checkpoint blockade cancer immunotherapy.
Wuhan Endoangel Medical Technology Co. Ltd.’s artificial intelligence (AI)-assisted real-time quality control and auxiliary diagnosis system for lower gastrointestinal endoscopy has been approved by China’s NMPA.
Distant metastasis and drug resistance are the main causes of colorectal cancer (CRC)-derived mortality. Identifying the underlying mechanisms driving metastasis is key for improving its therapy. Epithelial-to-mesenchymal transition (EMT) promotes the migration and invasion of tumor cells, allowing them to metastasize distant organs. Chinese researchers put the focus on dishevelled segment polarity protein 3 (DVL3) due to its involvement in the Wnt signaling pathway.
Presentations at the Digestive Disease Week 2023 conference highlighted the strong performance of non-invasive tests for early-stage colorectal cancer. Both Guardant Health Inc. and Exact Sciences Corp. aim to increase acceptance of their tests for CRC to drive higher screening rates, as the preparation and invasive nature of colonoscopy continue to depress participation, even as rates of CRC are rising sharply among younger adults.
