Preventing Oral Mucositis With Hybrid Adenoretroviral Vectors

Description of Invention: Researchers at the National Institutes of Health have recently developed a novel method utilizing adenoretroviral vectors to safely and swiftly prevent oral mucositis induced by radiotherapy. This clever new method developed by National Institute of Dental and Craniofacial Research (NIDCR) researchers combines the advantages of adenoviral and retroviral vectors to efficiently shuttle into salivary glands a non-integrating vector that can produce a therapeutic protein for intermediate to long-term treatment. This approach is anticipated to result in fewer side-effects than current therapies.

The market for the treatment of mucositis, the painful inflammation and ulceration of the mucous membranes lining the digestive tract, is estimated to be in excess of $5 billion worldwide. Up to 80% of all patients receiving radiotherapy and approximately 40% of all chemotherapy patients develop oral mucositis, and almost all patients receiving radiotherapy for head and neck cancer and those undergoing stem cell transplantation develop mucositis.

Applications

  • Prevention of radiation-induced oral mucositis.
  • Transduction of genes encoding secretory proteins with clinical uses for intermediate to long-term treatment (e.g., 4-8 weeks).

Advantages

  • Safe.
  • Reduced potential for side-effects.
  • Efficient production of transduced genes.
  • Efficient in vivo/in vitro transduction.
  • Extra-chromosomal location.

Development Status: Pre-clinical.

Mutations of the ERBB4 Gene in Melanoma

Description of Invention: Cutaneous malignant melanoma is the most common fatal skin cancer, and the incidence of this disease increases each year. The average survival time for patients diagnosed with malignant melanoma is less than ten months. Consequently, it is important to identify and understand genetic alterations leading to malignant melanoma so that new treatment strategies can be developed.

Protein tyrosine kinases (PTKs) have been associated with a wide variety of cancers, including melanoma. Using high-throughput gene sequencing, the NIH inventors have analyzed PTKs in melanoma and have identified several novel somatic alterations, including alterations in ERBB4. This invention provides methods of identifying specific inhibitors to ERBB4 that could be used to treat patients with ERBB4 mutations. Given the recent success of small molecule protein kinase inhibitors and specifically inhibitors to EGFR, this invention could be used to further the development of specific inhibitors to ERBB4 and improve existing melanoma treatments for patients with these mutations.

Applications

  • Diagnostic array for the detection of ERBB4 mutations.
  • Method of identifying ERBB4 inhibitors as therapeutic agents to treat malignant melanoma patients.

Development Status: The technology is currently in the pre-clinical stage of development.

Market

  • Approximately 160,000 new cases of melanoma are diagnosed worldwide each year. Malignant melanoma is increasing faster than any other cancer.
  • Melanoma is the most prevalent cancer among women between the ages of 25 and 29 and the second most prevalent cancer among women ages 30-34.
  • Cutaneous malignant melanoma is the most serious form of skin cancer and accounts for about 75% of all skin cancer deaths.
  • One person dies from melanoma every hour.

Genetically Modified Stem Cells for Personalized Therapy of Single Gene Disorders

Description of Invention: This technology is directed to individualized therapies of single gene disorders by introducing a patient's own genetically modified adult stem cells to the damaged tissue. Diseases arising from single gene disorders affect approximately 1% of the human population. Unlike most current treatments for such diseases, which are non-specific and symptom-based, this technology specifically addresses the underlying pathology of the disorder.

Many single gene diseases are accompanied by tissue damage and inflammation. This technology exploits the inflammatory response, which includes homing of mesenchymal stem cells to the site of damage, for therapeutic purposes. The inventors have genetically modified adult stem cells to produce silencing RNA specific to the defective protein in the damaged tissue. The silencing RNA can inhibit the source of the pathology and promote the growth and differentiation of genetically modified stem cells adjacent to the damaged tissue which can support the tissue healing process. Start Printed Page 4575Additionally, the risk of developing Graft Versus Host Disease is eliminated by utilizing the patient's own stem cells.

Proof of concept has been demonstrated in the vascular type of the Ehlers-Danlos Syndrome (VEDS). Using tissues isolated from VEDS patients, siRNA was shown to correct the mutational defect. The siRNA not only inhibited the production of the mutant protein but also restored the normal, non-pathological structure of the wild-type protein in the tissue.

This technology may be particularly applicable to patients with mutations in structural proteins of the extracellular matrix, as presented in diseases such as osteogenesis imperfecta, Marfan syndrome, and Ehlers-Danlos syndrome (EDS).

Potential Applications and Advantages

  • Therapeutic for diseases arising from single gene disorders.
  • Specific to the underlying disease unlike most current treatments.
  • Therapeutic cells are recruited to the specific site of damage.
  • Subsequent differentiation and localization of stem cells is therapeutic to the damaged tissue.

Development Status: Pre-clinical; however, patients with vascular type of the Ehlers-Danlos syndrome (VEDS) are being recruited for observational studies.

HIV-1 Infection Detection Assay for Seroconverted HIV-1 Vaccine Recipients

Description of Invention: Available for licensing and commercial distribution is a serological test specifically designed to distinguish between antibodies generated in HIV vaccine recipients and those generated in a natural HIV infection. The method is useful in HIV vaccine development and clinical studies as it can readily detect early breakthrough infections in seroconverted vaccine recipients, thus providing the information required to determine vaccine efficacy. The test kit includes diagnostic peptide fragments derived from human immunodeficiency virus-1 (HIV-1). The peptide epitopes are primarily derived from the GAG-p6 and gp41 genes. These epitopes are broadly reactive with early sera from HIV infected individuals, but do not illicit protective antibodies, or immunologic cytotoxicity, and thus can readily be excluded from current and future HIV-1 vaccine candidates.

Applications

  • Vaccine efficacy studies; Detection of early seroconversion in vaccine recipients.
  • Distinguishing between healthy vaccine recipients and natural HIV infection.
  • Blood bank screening.

Advantages: Cost effective method to determine vaccines efficacy in clinical studies.

Market: In spite of the more than twenty years of efforts to develop HIV vaccine, such vaccine does not yet exist. While treatment of HIV/AIDS with antiretroviral drugs can reduce viral load and extend life, this approach does not provide a true cure and cannot stop the HIV/AIDS pandemic. The medical community therefore fully recognizes the urgency to develop an effective vaccine for HIV/AIDS. In spite of the many challenges in the development of such vaccine (out of the 75 vaccine candidates that entered clinical trials over the years only 3 have reached the stage of large-scale efficacy trials and to date none have prove efficacious) the efforts in this area will continue to receive high priority by the public sector and high level of research funding. In order to make progress in this area, public sectors in many countries as well as not-for-profit NGOs have in recent years developed strategies and provided incentives to the private sector to continue with the efforts through the creation of public-private partnerships. Development of tools that can facilitate clinical trials, such as the present invention, may therefore be a good commercial opportunity, in particular in light of the potential market for HIV/AIDS vaccine. While the market for therapeutic drugs against HIV/AIDS across the seven major markets is now approaching $11.0 billion annually and growing at about 12.8% a year, the International AIDS Vaccine Initiative (IAVI) projects $2.5 billion to $5.5 billion in peak annual revenues of any new vaccine. This projection is based on peak demand of between 38 and 152 million courses (two doses per one course) depending on the vaccine profile. The projection also takes into consideration a tiered pricing and this projected revenue represents 5% to 13% of the total global vaccine market.
