Licensing Opportunity and/or Cooperative Research and Development Agreement (“CRADA”) Opportunity: Novel Methods and Compositions for Diagnosing, Treating and Monitoring Psychiatric Disease

AGENCY:

NIDA, NIH, DHHS.

ACTION:

Notice.

SUMMARY:

The National Institute on Drug Abuse (NIDA), Cellular Neurobiology Research Branch, is seeking Licensee(s) and/or proposals from potential collaborators for a Cooperative Research and Development Agreement (CRADA) to participate in the exploration of the clinical significance of recent studies in which NIDA has identified variations in the isoforms of neural cell adhesion molecule (N-CAM) associated with neuropsychiatric disorders. Elevations in certain isoforms are associated with specific neuropsychiatric disorders. These specific variations in the levels of N-CAM suggest that diagnostic techniques or therapeutic interventions could be based on the observed alterations in cell adhesion molescules. A provisional patent application relating to the N-CAM isoforms associated with neuropsychiatric disorders has been filed. Any successful CRADA collaborator may need to negotiate a license to the provisional patent application in order to commercialize developments under the CRADA. Contact information to apply for a license to the provisional patent application appears below.

DATES:

Interested CRADA applicants should submit written notice of intent to apply within 45 days of the date of this notice. NIDA will consider all written proposals received within 60 days of the date of publication of this notice. CRADA proposals submitted thereafter may be considered if a suitable CRADA collaborator has not been found. There is no specific deadline for licensing applications.

SUPPLEMENTARY INFORMATION:

Respondees interested in licensing the invention will be required to submit an Application for License to Public Health Service Inventions. Inventions described in the patent application are available for either exclusive or non-exclusive licensing in accordance with 35 U.S.C. 207 and 37 CFR Part 404.

A “Cooperative Research and Development Agreement” or “CRADA” is the anticipated joint agreement to be entered into by NIDA and a collaborator pursuant to the Federal Technology Transfer Act of 1986 as amended by the National Technology Transfer and Advancement Act of 1995 (Pub. L. 104-113 (Mar. 7, 1996)) and by the Executive Order 12591 of October 10, 1987. The CRADA would pertain to inventions conceived or reduced to practice after the effective date of the CRADA. CRADA applicants should be aware that a license to the above mentioned patent rights may be necessary in order to commercialize products arising from a CRADA.

A CRADA is an agreement designed to enable certain collaborations between Government laboratories and non-Government laboratories. It is not a grant, and is not a contract for the procurement of goods/services. The NIDA is prohibited from transferring funds to a CRADA collaborator. Under a CRADA, NIDA can contribute facilities, staff, materials, and expertise to the effort. The collaborator may contribute facilities, staff, materials, expertise, and funding to the collaboration. The CRADA collaborator receives an exclusive option to negotiate an exclusive or non-exclusive license to Government intellectual property rights arising under the CRADA in a pre-determined field of use and may qualify as a co-inventor of new technology developed under the CRADA.

NIDA's principal objectives under a License and/or CRADA would be the development and timely commercialization of new diagnostics and/or therapeutics for specific neuropsychiatric disorders and rapid publication of results related to these research projects.

Scientists at NIDA have discovered that distinct isoforms of N-CAM are elevated in the cerebrospinal fluid (CSF) and brains of patients diagnosed with specific neuropsychiatric disorders including schizophrenia, bipolar disorder and depression. A distinct isoform with molecular weight 105-115 kDa is present in elevated levels in both the CSF and brain tissues of patients with schizophrenia. The secreted (SEC) N-CAM isoform was elevated in brain tissue from bipolar disorder patients. Elevation of at least one isoform, the variable alternative spliced exon, or VASE isoform, is correlated significantly with behavioral ratings in patients with schizophrenia but not affective disorders. Thus, patients with neuropsychiatric disorders exhibit variations in N-CAM isoforms which are specific for their particular disorder. The specific association of these variations in N-CAM isoforms with particular neuropsychiatric disorders suggests the potential for development of therapeutic interventions, clinical trials for monitoring treatment response, and diagnostic methods of schizophrenia, bipolar disorder, depression and related diseases.

Present treatment of schizophrenia, bipolar disorder, depression and related diseases is inadequate. Existing treatments may have serious side effects and do not prevent the progression of schizophrenia. Development of an effective treatment requires a greater understanding of the biological mechanisms underlying the disease conditions. Through NIDA's discovery of an association between clinical abnormalities and alterations in the level of N-CAM, a greater understanding of the disease process is now possible, and this discovery suggests possible therapies.

In addition to inadequate existing treatments, there is presently no definitive diagnostic test for schizophrenia. Determination of the presence of the various criteria characteristic of schizophrenia is made by a trained clinician and is somewhat subjective. NIDA's discovery suggests that altered levels of N-CAM isoforms in the CSF may be the basis of an objective diagnostic test.

N-CAM is a cell recognition molecule with four major isoforms present in the brain. N-CAM isoforms are membrane-associated glycoproteins, either transmembrane glycoproteins or glycosylphosphatidyl inositol-anchored glycoproteins. There is also a secretory isoform. Membrane-associated N-CAM has several roles in cellular organization and development of the central nervous system. An important aspect of N-CAM activity is the regulation of adhesion of brain cells. Adhesion of neural to glial cells is mediated by N-CAM binding. N-CAM is also involved in memory processes, intracellular signal cascades, and neurite outgrowth. N-CAM is thought to be a neuronal protein and is known to be associated with synaptosomes, vesicles recovered from neuronal preparations. Thus, alterations in N-CAM influence brain structure, learning, and psychiatric systems, as shown in the recent research that NIDA is seeking to develop with a collaborator.

The proposed collaboration would include in vivo investigations of production of N-CAM isoforms and release of N-CAM isoforms into CSF. Measurements on N-CAM production and release would be correlated with the clinical status of patients. The possibility of using these correlations to develop a diagnostic method will be investigated. Potential therapeutic compounds would be tested for effects on the biochemical parameters and the clinical status of patients. The collaboration would also involve in vitro investigation of N-CAM fragment production and release from brain tissue.

The proposed duration of the CRADA is two (2) years. However, the duration could be as long as five (5) years depending on the nature of the research plan developed by the parties.

The role of NIDA under the proposed CRADA may include the following, and other relevant scientifically appropriate collaborative research projects will be considered:

(1) Provide further characterization of association between N-CAM variations with neuropsychiatric disorders.

(2) Perform in vitro determinations of N-CAM fragment production and release from brain tissue.

(3) Provide in vitro assessment of possible therapeutic compounds.

(4) Monitor the efficacy of therapeutic compounds through biochemical methodology.
