Human Papilloma Viruses (HPV) is a very common virus; nearly 80 million people—about one in four—are currently infected in the United States. HPV is a group of more than 150 related viruses. Each HPV virus in this large group is given a number which is called its HPV type. HPV is named for the warts (papillomas) some that HPV types can cause. Some other HPV types can lead to cancer, especially cervical cancer.

• Topoisomerase 3B (TOP3B) is the only topoisomerase that can act on RNA as well as DNA. Thus, it is a target of interest for the development of cancer therapies and RNA viral infection therapies. TOP3B is not an essential gene for carcinogenesis, but a subset of cancer cells with pre-existing genome instability are particularly vulnerable to the inactivation of TOP3B. While inhibitors for other topoisomerases are among the most potent and widely used anticancer agents, there are no known inhibitors of TOP3B.

Drug delivery technologies have long claimed the ability to selectively deliver therapeutic cargo to target cells. Despite advances in nanomedicine and drug delivery systems, there are no targeted nanoscale drug delivery technologies on the market. Thus, there is still tremendous potential in improved therapeutic efficacy when targeted drug delivery is achieved. 

Griffithsin (GRFT) is a lectin with potent antiviral properties that is capable of preventing and treating infections caused by a number of enveloped viruses (including HIV, SARS, HCV, HSV, and Japanese encephalitis) and is currently in clinical development as an anti-HIV microbicide. In addition to its broad antiviral activity, GRFT is stable at high temperature and at a broad pH range, displays low toxicity and immunogenicity, and is amenable to large-scale manufacturing.

The subject invention describes a new class of compounds (such as peptides or mimetics) that target viral RNAs and inhibit the viral life cycle by blocking the viral recognition process. More specifically, these compounds are the first against an RNA Target - currently there are no clinical drugs against RNA targets in the treatment of any type of human disease.

The National Cancer Institute (NCI) Division of Cancer Epidemiology and Genetics (DCEG)  Immunoepidemiology Branch is seeking statements of capability or interest from parties interested in collaborative research to further co-develop a gene-based diagnostic for Hepatitis C virus (HepC, HCV).

T cells currently employed for T cell-based immunotherapies are often senescent, terminally differentiated cells with poor proliferative and survival capacity. Recently, however, scientists at the National Cancer Institute (NCI) identified and characterized a new human memory T cell population with stem cell-like properties. Since these T cells have limited quantities in vivo, the scientists have developed methods by which high numbers of these cells can be generated ex vivo for use in T cell-based immunotherapies.

Hydrogels represent an attractive controlled drug-delivery system that have been used in various clinical applications, such as: tissue engineering for wound healing, surgical procedures, pain management, cardiology, and oncology. High-water content of hydrogels confers tissue-like physical properties and the crosslinked fibrillar network enables encapsulation of labile small molecule drugs, peptides, proteins, nucleic acids, proteins, nanoparticles, or cells.

Despite several partially effective prophylactic vaccines for SARS-CoV-2 exist, patients worldwide still succumb to COVID-19. New therapeutics to treat this disease are still needed.  Upon host invasion, a critical step in the pathogenesis of COVID-19 is intracellular replication of SARS-CoV-2 before viral particles invade nearby healthy cells. This triggers an extreme inflammatory response that may lead to acute respiratory distress syndrome (ARDS) or transmission to another host.

This technology describes additional methods of using the griffithsin anti-viral polypeptides described in related NCI invention (reference number E-106-2003).  Specifically, this invention describes the use of GRFT to inhibit viral infection of hepatitis C viral infection, a severe acute respiratory syndrome (SARS) viral infection, an H5N1 viral infection, or an Ebola viral infection.
