Live Attenuated Vaccine To Prevent Disease Caused by West Nile Virus

Description of Technology: West Nile virus (WNV) has recently emerged in the U.S. and is considered a significant emerging disease that has embedded itself over a considerable region of the U.S. WNV infections have been recorded in humans as well as in different animals. From 1999-2014, WNV killed 1,765 people in the U.S. and caused severe disease in more than 41,762 others. This project is part of NIAID's comprehensive emerging infectious disease program.

The methods and compositions of this invention provide a means for prevention of WNV infection by immunization with attenuated, immunogenic viral vaccines against WNV. The invention involves a chimeric virus form comprising parts of WNV and Dengue virus. Construction of the hybrids and their properties are described in detail in multiple publications. The WNV chimeric vaccine does not target the central nervous system, which would be the case in an infection with wild type WNV. Importantly, two successful Phase I clinical trials were recently carried out with the vaccine. The live attenuated WNV vaccine is safe, well-tolerated, and immunogenic in healthy adult volunteers. Furthermore, the vaccine virus may also be considered for use as a safe reagent handled at bio-safety level 2 facilities for WNV diagnosis and surveillance.

Potential Commercial Applications

  • Human West Nile vaccine
  • Veterinary West Nile vaccine
  • West Nile Virus diagnostics
  • West Nile Virus therapeutics

Competitive Advantages

  • Low cost of manufacture
  • Proven chimeric vaccine technology
  • Phase I clinical data available

Development Stage

  • In vivo data available (animal)
  • In vivo data available (human)

Three-Dimensional Curved Catheter for Right Atrial Appendage Traversal

Description of Technology: Available for licensing and commercial development is a three-dimensionally configured curved catheter for safe traversal of the right atrial appendage (RAA). The device is configured to optimize one-way access of the pericardial space through the right atrium and into the RAA reducing the risk of coronary lacerations. Specifically the curved catheter is best described in three segments: a proximal segment, a transitional segment and a distal segment; the transition segment having a clockwise spiral shaped curvature. When inserted into a patient, the proximal segment is positioned within the inferior vena cava, the transition segment extends across the caval-atrial junction and curves rightward, forward, and upward such that the catheter abuts a right lateral wall of the right atrium, and the distal segment curves leftward, forward, and upward from the transition segment through the right atrium such that the catheter abuts an anterior wall of the right atrium adjacent to the RAA. The catheter is configured to guide a coaxial puncturing device to through the superior left sulcal wall of the RAA.

Potential Commercial Applications

  • Left atrial appendage ligation
  • Circumferential tricuspid annuloplasty
  • Epicardial ablation

Competitive Advantages: Reduced risk of coronary or myocardial laceration

Development Stage

  • Early-stage
  • Prototype

Pseudomonas Exotoxin A With Modified Furin Cleavage Site

Description of Technology: Immunotoxins kill cancer cells while allowing healthy, essential cells to survive. As a result, patients receiving immunotoxins are less likely to experience the deleterious side-effects associated with non-specific therapies such as chemotherapy. In order to make an effective immunotoxin, three components are generally required: A targeting domain, a furin cleavage site (FCS), and a toxic payload molecule (such as Pseudomonas exotoxin A (PE)). The purpose of the FCS is to allow the toxin domain to be processed by the target cell so that it can exert its toxic effect. This technology concerns the engineering of FCS in order to improve the efficacy of specific immunotoxins having distinct targeting domains. Several novel FCS have been generated which can be substituted for the native FCS in PE. By using specific FCS with different targeting moieties, it is possible to engineer an immunotoxin that is better suited to treating specific types of cancer.

Potential Commercial Applications

  • Essential for the payload component of immunotoxins
  • Treatment of any disease associated with increased or preferential expression of a specific cell surface receptor
  • Specific diseases include hematological cancers, lung cancer (including mesothelioma), ovarian cancer, breast cancer, and head and neck cancers

Competitive Advantages

  • Designing specific furin cleavage sites for particular immunotoxins can improve cleavage and enhance toxin efficacy, resulting in improved therapeutic effectiveness
  • Targeted therapy decreases non-specific killing of healthy, essential cells, resulting in fewer non-specific side-effects and healthier patients

Development Stage: In vitro data available.
