New Epitopes Recognized by Antibodies Against Human and Avian Influenza for Vaccines and Diagnostic Assays

Description of Technology: Available for licensing and commercial development are intellectual properties drawn to peptides and polypeptides that elicit immunogenic responses in a mammal; especially neutralizing antibodies, against human and avian influenza strains H1N1, H3N2, H5N1 and H7N7. Materials in the form of immunogenic compositions including these peptides and polypeptides can also be in-licensed along with the patent rights. Pharmaceutical compositions including these peptides and polypeptides with or without adjuvants are within the scope of the invention. Nucleic acids and expression cassettes encoding these peptides and polypeptides are also within the scope of the invention. Methods of inhibiting infection by influenza, with or without cell entry, are also within the scope of the invention using the aforementioned peptides and polypeptides.

Applications: Vaccines; Therapeutics; Diagnostics; Influenza.

Trifunctional Imaging Agent for Monoclonal Antibody Tumor-Targeted Imaging

Description of Technology: Available for licensing and commercial development is a novel lysine-based trifunctional chelate which bears both a chelating moiety (CHX-A″) for sequestering radiometals (86 Y or111 In) and a near-infrared dye, e.g., Cy5.5, for dual modality PET (or SPECT) and fluorescence imaging. Successful conjugation of monoclonal antibody trastuzumab (Herceptin) or cetuximab (Erbitux) has also been achieved by efficient thiol-maleimide chemistry, Start Printed Page 68589thereby yielding an immunoconjugate (Signaling agent (Cy5.5-Lys(SMCC)-CHX-A″) conjugated to trastuzumab) or (Signaling agent (Cy7-Lys(SMCC)-CHX-A″) conjugated to cetuximab). Both specifically target antigen expressing cells and internalization of the agent has been imaged over time. Trastuzumab can be radiolabeled with isothiocyanate derivatives of the bifunctional chelating agents 1B4M (2-(4-aminobenzyl)-6-methyldiethylenetriaminepentaacetic acid); and CHX-A″ (N-[(R)-2-amino-3-(p-aminophenyl)propyl]-trans-(S,S)-cyclohexane-1,2-diamine-N,N,N′,N″,N″-pentaacetic acid).

Applications: Imaging; Diagnostics.

Nanoparticles for Imaging: Targeted Nanoparticles That Can Be Imaged Through Magnetic Resonance, Optical, and Radioisotope Imaging

Description of Technology: Available for licensing and commercial development are patent rights covering tri-imageable nanoparticles which have great potential for application in the laboratory and clinic for labeling at the cellular level, diagnostics, and drug delivery. The particle includes a silica encased ultrasmall superparamagnetic iron oxide (SPIONs) that can be detected using MRI. A fluorescent probe (e.g., Cy5.5) for optical imaging is embedded in the silica. The resulting particles are about 20-25nm in diameter. Target specific antibodies are attached to the surface of the particles. Chelated to the antibodies is a radioisotope (e.g., Indium-111) useful for particle quantification and can be imaged through techniques such as single photon emission computed tomography (SPECT) or positron emission tomography (PET). A graphical representation of an exemplary nanoparticle according to the invention is shown in the accompanying illustration.

Applications: Imaging; Cancer; Multiple Sclerosis.
