Methods of Detecting Loss of Heterozygosity and Damaging Mutations in Immune-Related Genes Using Liquid Biopsies

Summary: 
The National Cancer Institute (NCI) seeks co-development partners and/or licensees for a liquid biopsy diagnostic assay capable of detecting loss of heterozygosity (LOH) and somatic mutations in genes important for antigen processing and presentation and interferon-γ response pathways.

Method for HLA LOH Detection in Liquid Biopsies

Human leukocyte antigen (HLA) LOH (LOH) is a known resistance mechanism by which cancers evade T cell receptor-(TCR-)based immunotherapies. This class of therapies includes immune checkpoint inhibition (ICI, e.g., Pembrolizumab), engineered TCR (T cell receptor)-T cell adoptive transfer, tumor infiltrating lymphocytes (TIL), T-cell engagers, and other modalities. Dozens of therapies in this category were developed with many in clinical trials. The resistance mechanism noted here, HLA LOH, causes these therapies to fail.

Intralipid as a Contrast Agent to Enhance Subsurface Blood Flow Imaging

This technology includes a blood flow imaging method that allows for a higher density of smaller particles to be detected. Current imaging methods that are based on Doppler measurements are limited by the discontinuity in the capillary flow in the space between red blood cells. The core technology is to use a scattering agent to enhance capillary flow or microcirculation. This technology has been tested for optical coherence Doppler tomography, but can be expended to any Doppler based flow imaging techniques such as laser speckle imaging.

Novel Small Molecule Agonists of the Relaxin Receptor as Potential Therapy for Heart Failure and Fibrosis

The present invention is directed to novel small molecule agonists of the mammalian relaxin family receptor 1 (RXFP1), including human RXFP1. Activation of RXFP1 induces: 1) vasodilation due to up-regulation of the endothelin system; 2) extracellular matrix remodeling; 3) moderation of inflammation by reducing levels of inflammatory cytokines; and 4) angiogenesis. Small molecule agonists of RXFP1 may be useful in treating acute heart failure (AHF), scleroderma, fibrosis, other conditions associated with the biology of relaxin, and in improving reproductive health and wound healing.

Zip14-AAV Genetic MRI Reporter System for Non-Invasive Cell & Gene-Therapy Tracking

This technology includes a gene-based magnetic resonance imaging (MRI) reporter platform that harnesses adeno-associated virus (AAV) delivery of the metal transporter Zip14 to create image contrast wherever the gene is expressed. By driving Zip14 from cell-specific promoters, investigators obtain robust, long-lasting signal changes on standard clinical MRI sequences (e.g., MPRAGE and GRE), enabling real-time visualization of living cells and their gene-expression patterns.

Gene Signature for Predicting Solid Tumors Patient Prognosis

HCC is the most frequent malignant tumor in the liver and the third leading cause of cancer death worldwide.  A progressive sequence of somatic mutations and epigenetic changes of oncogenes or tumor suppressor genes are believed to cause tumor development. However, high genomic instability in tumors causes the accumulation of genomic aberrations that do not contribute to tumor progression. Therefore, it is important to distinguish between ''driver'' mutations that are functionally important and ''passenger'' mutations that do not provide a selective advantage to the tumor cells.

Non-invasive diagnostic and prognostic assay for early stage lung cancer

In the United States alone, one of four cancer deaths occur from lung cancer and there are over 8 million individuals considered to be at high-risk due to cigarette smoking and other behaviors. It's well known that early detection of cancer significantly improves survival of this disease, however a lack of lung cancer screenings and analysis precludes fast results at a low cost.

A Viral Exposure Signature to Define and Detect Early Onset Hepatocellular Carcinoma

Early detection of liver cancer, such as hepatocellular carcinoma (HCC), is key to improve cancer-related mortality. More than 800,000 people are diagnosed with this cancer each year throughout the world. Liver cancer is also a leading cause of cancer deaths worldwide, accounting for more than 700,000 deaths each year. Currently, millions of Americans and possibly billions in the world are considered at risk for developing liver cancer.

EV-D68 Monoclonal Antibodies Isolated from Immunized Rhesus Macaques

Enterovirus D68 (EV-D68) has been linked to the widespread outbreaks of respiratory illness and acute flaccid myelitis (AFM) in the United States and Europe in 2014, 2016, and 2018. Although EV-D68 is now the most frequently encountered enterovirus (41.1% of cases), with an estimated global prevalence of 4%, there are no specific, FDA-approved therapeutic interventions targeting this virus.
