SUPPLEMENTARY INFORMATION: Technology description follows:

Base-Covered HIV-1 Envelope Ectodomains and Their Use

    Description of Technology: Researchers at the Vaccine Research 
Center (``VRC'') of the National Institute of Allergy and Infectious 
Diseases (``NAID'') continue to pursue a safe and effective HIV-1 
vaccine to combat the HIV-1/AIDS pandemic.
    To this end, researchers have engineered the soluble HIV-1 
ectodomain trimer so that it is stabilized in its prefusion 
conformation by artificial disulfides, helix-disrupting prolines, and 
other structure-based alterations. However, mice and non-human primates 
immunized with these engineered soluble HIV-1 trimers produced a 
significant (>90% in some cases) immune response to the exposed trimer 
base.
    VRC researchers further modified the engineered prefusion soluble 
HIV-1 trimers by adding N-linked glycans to specific sites on the 
protein's base to block this immunodominant surface. They found that 
these N-linked glycans did reduce production of non-neutralizing 
antibodies directed to the trimer base. These soluble, glycan-masked 
prefusion HIV-1 trimers are envisioned as being a part of a 
heterologous prime-boost vaccine regimen.
    This technology is available for licensing for commercial 
development in accordance with 35 U.S.C. 209 and 37 CFR part 404, as 
well as further development and evaluation under a research 
collaboration.
    Potential Commercial Applications:

<bullet> Vaccine for prevention of HIV-1 infection
<bullet> Therapeutic vaccine for treatment of HIV-1 infection

    Competitive Advantages:

<bullet> Currently, no licensed HIV vaccine exists

    Development Stage:

<bullet> Animal studies
