Method of Treating Fumarate Hydratase-Deficient Kidney Cancer

Description of Technology: Patients having germline fumarate hydratase (“FH”) gene mutation are predisposed to develop aggressive kidney cancer with few treatment options and poor therapeutic outcomes. NCI scientists have identified a tyrosine kinase inhibitor vandetanib that is highly cytotoxic to kidney cancer cells both in vitro and in vivo. C-Abl activity is upregulated in FH-deficient kidney tumors and vandetanib efficacy is a direct consequence of c-Abl inhibition. It was also found that combining metformin enhanced the cytotoxic effect of vandetanib by inhibiting NRF2 transcriptional activity in a SIRT1-dependent manner. Thus dual inhibition of c-Abl and NRF2 activity with vandetanib and metformin is a novel therapeutic approach to target glycolytically dependent, oxidatively stressed tumors.

Potential Commercial Applications: Therapies for treating FH-deficient kidney cancer and glycolytically dependent, oxidatively stressed tumors.

Competitive Advantages:

  • Specificity of mode of action may reduce potential side-effects.
  • Novel mode of action may increase market competition.
  • No effective therapy is currently available for patients with advanced FH-deficient kidney cancer.

Development Stage:

  • In vitro data available.
  • In vivo data available (animal).

Therapeutic and Prophylactic Anti-Influenza Virus Neuraminidase 1 (N1) Antibody (CD6) With a Novel Epitope That Spans Neuramindase (NA) Dimers

Description of Technology: Influenza virus neuramindase (NA) protein is a surface protein that plays an essential role in virus replication. Drugs and antibodies that block NA function can reduce both the symptoms and the length of illness; however, variants of influenza virus are resistant to NA inhibitors. The neuramindase 1 (N1) subtype of NA is important because it is found in the two pandemic H1N1 influenza virus strains (1918 Spanish flu and 2009 swine flu) and the H5N1 avian influenza virus. Anti-neuramindase antibody CD6 is a novel antibody that spans a conserved 30 amino acid epitope across the lateral face of a neuramindase (NA) dimer.

The subject technology may offer an alternative to therapeutic NA inhibitors currently available. CD6 is a potent monoclonal antibody against N1 subtypes of NA that inhibits the enzymatic activity of the NA protein, including NA variants resistant to NA inhibitors. In a murine model of infection, a single dose of antibody was protective against lethal challenge with H1N1 influenza virus. The CD6 antibody can potentially be used in combination with other antibodies in an antibody “cocktail” or in conjunction with other therapeutic agents. Additionally, this unique anti-NA antibody may be useful in combination with known neutralizing anti-hemagglutinin (HA) antibodies.

Potential Commercial Applications:

  • Prophylactic and therapeutic against influenza virus infections.
  • Diagnostic tests for influenza virus infections.
  • Reagent to measure the potency of H1N1 NA in influenza virus vaccines.

Competitive Advantages:

  • Monoclonal antibody demonstrated to be effective against circulating H1N1 influenza viruses.
  • Monoclonal antibody binds a novel, conserved epitope spanning NA dimers.
  • Monoclonal antibody is well-suited for an antibody cocktail that includes anti-HA antibodies.

Development Stage:

  • Early-stage.
  • In vitro data available.
  • In vivo data available (animal).

Confocal Laser Device and Method for Evaluating the Optical Properties of Intraocular Lenses (IOLs) Including Toric IOLs

Description of Technology: This innovative technology includes a confocal laser device and methodologies to evaluate the optical properties of spherical and toric Intraocular Lenses (IOLs). Spherical and toric IOLs are implanted in the eye to treat cataracts and other conditions in order to correct vision after surgery. Toric IOLs, in addition to correcting spherical aberrations of the eye, correct asymmetrical aberrations of the eye such as astigmatism.

This technology includes the confocal laser device and methodology for assessing spherical IOLs with an integrated component for assessing toric IOLs. The IOL market is growing steadily and IOL technology is continually improving to correct complex vision errors. It is estimated that 3 million IOLs are implanted annually in the U.S. and 19.7 million worldwide. This device can be used to precisely assess IOL key properties such as dioptric power, cylinder power, optical plane orthogonality and IOL markings used for IOL positioning in the eye during surgery. Thus, this new technology provides a simple, noninvasive, accurate and objective methodology to evaluate IOL characteristics with higher accuracy and repeatability in wider power ranges compared to the conventional test Start Printed Page 39789methods. These IOL test capabilities can improve the safety and efficacy of IOL implants and ultimately lead to better cataract surgery success rates.

Potential Commercial Applications:

  • Development and implementation of novel test devices and independent methodologies for precise evaluation and validation of critical IOL characteristics.
  • Development and evaluation of novel IOL designs.

Competitive Advantages:

  • Higher accuracy.
  • Higher repeatability.
  • Larger range of positive and negative IOL dioptric power measurement.

Development Stage:

  • In vitro data available.
  • In situ data available (on-site).
  • Prototype.
