Potentiating Antibody Therapy by Targeting Complement Deposited on Cancer Cells

Monoclonal antibodies (mAbs) have become a mainstay of therapy for many cancers. However, antibody therapy is not completely effective in some applications due to loss of the target surface antigen on cancer cells. Such mAb-induced “escape variants” are no longer sensitive to the therapeutic mAb therapy. It was observed that the escape variants carried covalently bound complement activation fragments, especially C3d. NIH inventors have generated several C3d-specific mouse and rabbit monoclonal antibodies to re-target cells that have escaped from mAb therapy.

Preparation of Substituted Diarylpropanamides as RORgt Antagonists for the Treatment of Th17-related Autoimmune Diseases

This technology includes a series of diphenylpropanamides as potent and selective RORgt inhibitors for the treatment of Th17-related autoimmune diseases. The retinoic acid-related orphan receptor RORgt plays an important role in the differentiation of thymocytes, lymphoid tissue inducer cells, and inflammatory T helper-expressing interleukin 17a (Th17) cells. Small molecule RORgt inhibitors may provide means to regulate Th17 mediated immune response. The novel molecules have potential to treat Th17-related autoimmune diseases.

Generation of Anti-TAT FXN Polyclonal and Monoclonal Antibodies to TAT Domain for Use in Quantitating or Detecting TATFrataxin (TAT-FXN) and Analogs

This technology includes a strategy to generate antibodies of rabbit origin, both polyclonal and monoclonal, which have strong affinity to the TAT sequence and which enable specific immunocapture or immunodetection of TAT containing frataxin and analogs for quantitative or qualitative assays. In addition, antibodies that react with the FXN region have also been generated with this strategy. The HIV virus encoded a translational activator protein containing a 12 amino acid domain which permits transmembrane delivery of any therapeutic protein containing the sequence.

Mounted Nitrocellulose Membrane Plates for Aqueous Acoustic Dispensing Nanoliter-Scale Reverse Phase Protein and
Biological Arrays for Antibody-Based Protein Detection and Quantification

This technology includes the enablement of the nanoliter-scale transfer of biological liquids in array format from a microplate (source plate) containing cultured cells or other protein-containing mixtures onto a nitrocellulose membrane that has been mounted within a custom-designed target plate. Using this method and the prototype nitrocellulose target plate, reverse phase protein arrays can be generated in which protein levels from each well transferred onto the membrane can be detected and quantified.

A Method for the Measurement of Cellular FMRP Levels for High Throughput Screening and Diagnosis of Fragile X Syndrome

This technology includes a precise measurement assay of cellular FMRP levels in patients, which can assist in the diagnosis and assess the severity of Fragile X syndrome (FXS). FXS is an X-linked disorder that produces intellectual disability, cognitive impairment, epilepsy, depression and anxiety. FXS is caused by mutations in the Fragile X Mental Retardation-1 (FMR1) gene that result in the absence or a loss of function of its protein product, FMRP.

SARS-CoV-2 Neutralizing Antibodies and Synthetic Nanobody Library Using a Humanized Llama Framework Region

NCATS has developed a highly diverse synthetic library that will allow for the rapid identification of novel nanobodies that bind to a wide arrange of target antigens. The humanized framework used to construct the library will facilitate the transition of lead candidates into patient studies. Several highly potent SARS-CoV-2 nanobodies (antibodies) have been identified and are available for further development.

NCATS is actively seeking licensing for the 1) a synthetic library and 2) the potent neutralizing antibodies with activity against SARS-CoV-2.

Monoclonal Antibodies for the Recognition of Oncogene Fusions and Alveolar Rhabdomyosarcoma (ARMS) Diagnosis

This technology includes monoclonal antibody (mAb) that binds to the junction region of the PAX3-FOXO1 and PAX7-FOXO1 fusion protein for the diagnosis of Alveolar Rhabdomyosarcoma (ARMS). Specifically, two monoclonal antibodies (PFM.1 and PFM.2) have been isolated that recognize the 92kDa bands found uniquely to the pediatric striated muscle tumors of the type Alveolar Rhabdomyosarcoma (ARMS) carrying the characteristic t(2;13)(q35;q14) or t(1;13)(p36;q14) chromosomal translocations.

Diagnosis and Treatment of Pediatric Acute Neurologic Syndrome with Antineuronal Antibodies

The invention is a panel of five tests of patient sera for immune responses that may attack the brain and lead to the characteristic symptoms of pediatric acute neurologic syndrome (PANS). PANS is a condition defined by a sudden onset of obsessive-compulsive symptoms, eating restrictions, and other cognitive and/or behavioral symptoms. Currently, the diagnosis of PANS is made when other possible symptoms are ruled out, a diagnosis of exclusion.
