Government-Owned Inventions; Availability for Licensing

AGENCY: National Institutes of Health, Public Health Service, HHS.
ACTION: Notice.
SUMMARY: The inventions listed below are owned by an agency of the U.S. Government and are available for licensing in the U.S. in accordance with 35 U.S.C. 207 to achieve expeditious commercialization of results of Federally-funded research and development. Foreign patent applications are filed on selected inventions to extend market coverage for companies and may also be available for licensing.
ADDRESSES: Description of Technology:The invention offered here is a vaccine candidate that can potentially confer protection against many types of influenza. Current vaccines against influenza virus are comprised of inactivated virus or purified influenza virus proteins and are targeted primarily to induce neutralizing antibodies against the viral hemagglutinin (HA) protein. The virus can mutate or shift antigenic types of HA rapidly rendering the vaccines ineffective and thus the vaccine has to be evaluated yearly to predict next year's circulating strains for vaccine preparation. Unlike HA, the small M2 protein is highly conserved among different strains of influenza virus and thus vaccines based on the M2 protein have the potential to be effective against different strains of influenza. The current invention relates to peptide vaccines composed of the extracellular domain of the M2 protein (M2e) conjugated to a carrier protein. In animals studies a mutant diphtheria toxin-M2e--conjugate induced high antibody levels to both vaccine components in mice.

Therapeutic HIV Vaccine and Associated Protocols

Description of Technology:This technology describes a therapeutic HIV DNA vaccine to be administered to individuals who have previously experienced or are undergoing antiretroviral therapy (ART). The therapeutic DNA vaccine can also be administered in combination with a vector encoding an IL-15 and/or IL-15 receptor alpha (IL-15Ra) polypeptide. In primate studies, the technology was found to be particularly effective when the vaccine composition was administered by electroporation and expressed six (6) HIV antigens (including two (2) gag polypeptides and two (2) envelope polypeptides) and IL-15 and IL-15Ra. The antigens are typically modified with a destabilizing sequence, a secretory polypeptide and/or a degradation signal. Successive administration up to as many as nine resulted in continual boost of the immune response against the encoded antigen. A potent immunotherapeutic vaccine as described here could be an important technology for the fight against HIV/AIDS.

Applications:Therapeutic HIV DNA vaccines.

Development Status:Primate data available.
