Broadly Neutralizing Anti-HIV Monoclonal Antibody That Targets a New

Epitope on gp41

Description of Technology: Blocking entry of HIV into cells and vaccine development against HIV are the prime targets of HIV therapy and prevention, respectively. Current invention describes a monoclonal

Fab anti-HIV antibody isolated through panning against the chimeric construct NCCG-gp41 by Antibodies-by-Design (Morphosys). One of the antibodies has broadly neutralization ability against several

HIV subtypes in an envelope-pseudotyped-virus neutralization assay.

This antibody was also shown to have synergistic effect with a gp41- derived peptide discovered in this laboratory in inhibiting HIV-1 fusion.

Applications: Research tool or screening for HIV vaccine.

Advantages: Can be potentially used as a therapeutic agent to block

HIV-1 entry into cells.

Development Status: In vitro data available.

Market: For the development of drugs against HIV.

Polyamine Compounds That Bind Tar RNA of HIV and Methods of Treating

Viral Disorders

Description of Technology: Current HIV treatment involves applying cocktail of drugs targeting either virus entry or one of three viral enzymes. Because patients eventually develop resistance to the cocktail, a new class of drugs is urgently needed. Current invention describes a new class of polyamine compounds that specifically bind to

HIV RNA at micromolar range to prevent binding of viral RNA to viral proteins and therefore blocking viral replication. This differs with the mechanisms of current HIV drugs in the market and therefore offers new strategy in HIV treatment and prevention. Furthermore, this class of compound may aid future development of drugs targeting RNA.

Applications: Treatment and prevention of HIV infection.

Advantages: Novel strategy for HIV treatment and prevention;

Specific binding to HIV RNA and strong activity.

Development Status: In vitro data available.

Market: HIV therapeutics and preventatives.

Inventors: Daniel Appella et al. (NIDDK).

Publications: Manuscripts in preparation.

Patent Status: U.S. Provisional Application No. 61/123,076 filed 04

Apr 2008 (HHS Reference No. E-159-2008/0-US-01).

Licensing Status: This invention is available for exclusive or non- exclusive licensing.

Collaborative Research Opportunity: The NIDDK, Laboratory of

Bioorganic Chemistry, is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize the application of TAR-binding polyamines for the treatment of HIV infections.

Monoclonal Antibodies to HIV-1 Vpr

Description of Technology: Available for licensing are monoclonal antibodies against HIV-1 viral protein R (Vpr) and the respective hybridoma cell lines expressing the same. The antibodies provide a means for detecting HIV-1 Vpr. Currently, the mechanism of HIV pathogenesis believed to involve viral replication inside immune cells and other cells. At present, there are no clinical assays for detecting

HIV-1 Vpr. Vpr circulates at detectable levels in the blood and is likely derived from degraded virions or released from infected cells.

Vpr facilitates viral replication and disrupt normal cell function.

Thus measurement of Vpr levels in blood, extracellular fluid, and tissue may be of benefit in understanding the pathogenesis of HIV-1 infection and its myriad complications.

The hybridoma cell lines (9F12 and 10F2) were selected from a group of hybridoma cell lines. These antibodies can be used for detection, including immunoasssays (ELISA) and immunoaffinity-capillary electrophoresis. The amount of detected HIV-1 Vpr is compared to a standardized control sample for determining the progress of disease or the presence of known complications like neuropathy, dementia, metabolic syndrome, or nephropathy.

Ulrich (NIAID), John Yewell (NIAID).

Patent Status: U.S. Patent Application No. 11/630,880 filed 27 Jun 2005 (HHS Reference No. E-141-2003/0-US-03).

Licensing Status: Available for licensing.

Anti-Pax 2 Antibody

Description of Technology: Available for licensing and commercialization are anti-Pax 2 polyclonal antibodies that can be used for the detection of Pax-2 protein expression in a variety of kidney and neuronal tissues. Pax-2 protein, a transcription factor active during early kidney development, is expressed at high levels in almost all renal proliferative diseases such as renal cancer, polycystic kidney disease and acute renal failure.

The Pax-2 protein has also been linked to Wilms' tumor, a cancerous kidney tumor accounting for ~6% of childhood cancers, and for which

~500 new cases are diagnosed each year in the U.S. Wilms' tumors are hard to diagnose in the early stage because they can grow quite large without causing any pain. While abdominal ultrasound may be used for detection, it is not a practical screening test for otherwise healthy children. There are no blood tests or other tests for screening for

Wilms' tumors which, if diagnosed sufficiently early, may be treated with surgery, chemotherapy, and/or radiation therapy.

Page 48218

Potential applications of this technology may also include detection of Pax-2 protein in urine for both chronic and acute renal disease.

Applications: Diagnostics for renal diseases; Research tools for evaluating disease processes of the kidney and other tissues through

Pax-2 protein expression in the relevant tissues.

Development Status: Ready for commercialization.

Patent Status: HHS Reference No. B-039-1996/0--Research Tool.

Patent protection is not being pursued for this technology.
