A conserved viral peptide for use in cancer immunotherapy

Summary:

The National Cancer Institute (NCI) seeks research co-development partners and/or licensees for viral peptide (CE1)-based therapeutics for HCC prevention and treatment.

Description of Technology:

Hepatocellular carcinoma (HCC) is a common and aggressive primary liver cancer. It develops mainly from at-risk individuals with underlying chronic liver diseases, such as hepatitis and cirrhosis. HCC is a leading cause of cancer-related death worldwide and its global incidence and mortality rate continues to rise. The current methods for early detection, surveillance and treatment are suboptimal due to complex etiologies and intricate tumor biology.

Through serological profiling across three independent cohorts, researchers at the National Cancer Institute (NCI) have identified a common epitope (CE1) shared among protective viral antigens enriched in healthy individuals compared to HCC patients. A synthetic CE1 peptide was demonstrated to have utility in eliciting a T cell response to HCC cells and can be developed as an immunotherapy for HCC, such as a CE1-based HCC vaccine. Currently, as there are limited therapeutic options for HCC patients, novel treatments would offer tremendous commercial and public health benefits.

Potential Commercial Applications:

  • HCC prevention and treatment
  • Predictive biomarker for HCC risk
    • Serological response test
    • Patient stratification for CE1-based therapy
    • Monitoring the efficacy of the CE1-based vaccine

Competitive Advantages:

  • VirScan data support that this peptide correlates with better outcomes in HCC and breast cancer
  • CE1 peptide shows an immunomodulatory effect; immunomodulators are a promising approach to cancer treatment
  • CE1 peptide is biologically active in inducing T cell cytolytic activity
  • HCC cell killing in an HLA-specific manner
