MedicalResearch.com Interview with: Radek Spisek MD PhD Charles University in Prague  MedicalResearch.com: What is the background for this study? Response: Immune cytokine IL-15 is a highly promising immuno-oncology target that mobilizes the two most important cell types driving anti-cancer immune responses: cytotoxic T cells and natural killer (NK) cells. Stimulating IL-15 receptors on these cells represents a potent and complementary mechanism to existing cancer treatments, such as PD-1 checkpoint inhibitors or monoclonal antibodies. Sotio is developing an IL-15 superagonist, SO-C101, as a potent immunotherapy for patients with cancer. This study examined SO-C101 in multiple tumor mouse models alone and in combination with PD-1 inhibition.  (more…)

MedicalResearch.com Interview with: Dr. Kathryn Lang VP, Outcomes and Evidence Guardant Health  MedicalResearch.com: What is the background for this study? Response: Despite a wide variety of screening methods available and increasing public awareness of the value of early detection, colorectal cancer (CRC) remains a leading cause of cancer-related deaths.  However nearly 1 in 3 adults in the United States  is not compliant with screening recommendations, with most citing that current screening methods are time consuming, unpleasant (stool-based testing), and in the case of colonoscopy, invasive. A blood-based CRC screening test could improve compliance rates by providing physicians with an opportunistic, in-office screening modality. However, demonstrating the clinical utility of blood-based cell-free circulating tumor DNA (ctDNA) fractions  for the detection of cancer in asymptomatic individuals has thus far been challenged by the failure to achieve clinically meaningful sensitivity and specificity thresholds due to significantly lower tumor cell-free free DNA  fractions and the increasing relevance of biological confounders. The multi-modal approach of Guardant Health’s LUNAR-2 assay (genomics, methylation and fragmentomics) coupled with advanced bioinformatic analysis and a focused approach of honing in on the unique signals of CRC  has been shown in previously reported cohorts to perform with sensitivity and specificity which satisfies the needs of clinicians in screening for CRC.
