T Cell Receptors (TCRs) Specific for Mutant p53

National Cancer Institute (NCI) researchers have isolated T cell receptors (TCRs) reactive to the highly prevalent p53-R175H mutant in the context of the human leukocyte antigen (HLA) class II allele, HLA-DRB1*13:01. These TCRs can be used for a variety of therapeutic, diagnostic, and research applications. NCI seeks licensing and/or co-development research collaborations for TCRs that recognize the p53-R175H mutation and the associated HLA allele, and methods for identifying p53 mutation-reactive T cell receptors.

In vitro Generation of an Autologous Thymic Organoid from Human Pluripotent Stem Cells

The thymus is the only organ capable of producing conventional, mature T cells; a crucial part of the adaptive immune system. However, its efficiency and function are progressively reduced as we age, leading to a compromised immune system in the elderly. Moreover, production of T cells with specific receptors is an important concern for cancer immunotherapy. Current in vitro methods produce immature T cells that are not useful for therapy. Researchers at the National Cancer Institute (NCI) have generated an autologous thymic organoid from human pluripotent stem cells to address this problem. The organoid can be used to develop clinical applications such as production of autologous T and natural killer T (NKT) cells and reconstitution of the adaptive immune system. NCI is seeking licensees for the thymic organoid and the method of its generation to be used in a variety of clinical applications.

Efficient Methods to Prepare Hematopoietic Progenitor Cells in vitro for Therapeutic Use

Multi-potential hematopoietic progenitor cells (HPC) can differentiate into any class of blood cells, and are highly useful in regenerative medicine, immunology, and cancer immunotherapy. Current methods to generate HPCs are limited either due to the use of animal products, or the high cost and low efficiency of animal product free systems. Researchers at the National Cancer Institute (NCI) have developed a protocol to prepare HPCs from human induced pluripotent stem cells (hiPSC), using human mesenchymal stem cells (hMSC) in a three-dimensional (3D) co-culture condition. Thus, they are able to generate HPCs in a fully human, autologous system, which can be used to further generate immune cells for therapy. This protocol is adaptable to mass production by bioreactors. NCI seeks licensees for these methods of generating HPCs in a 3D co-culture with hMSCs to be used in a variety of applications such as treatment of blood disorders, regenerative medicine, and antibody production.

Use of Heterodimeric IL-15 in Adoptive Cell Transfer

Researchers at the National Cancer Institute (NCI) have developed a technology that provides methods of performing adoptive cell transfer (ACT), an immunotherapeutic approach for cancer treatment, by administering a heterodimeric Interleukin 15/Interleukin 15 receptor alpha (IL-15/IL-15Rα) complex (hetlL-15) in the absence of lymphodepletion, thereby eliminating any lymphodepletion-associated detrimental side effects.

Treatment Regimens for hetIL-15

Researchers at the National Cancer Institute (NCI) developed a treatment regimens for cancer and HIV using heterodimeric IL-15 (hetIL-15). The regimens allow access to B cell follicles, germinal centers, and tumor sites that are difficult for drug entry. A combination therapy for HIV infection is also described using hetIL-15 and a conserved element vaccine. Researchers seek licensing and/or co-development research collaborations for development and commercialization of treatment regimens for HIV infection.

Combination of Near Infrared Photoimmunotherapy Targeting Cancer Cells and Host-Immune Activation

Investigators at the National Cancer Institute (NCI) seek co-development partners and/or licensees for a new therapeutic approach that selectively targets cancer cells and prevents tumor regrowth. The novel method combines antibody-IR700 molecules and Near-Infrared Photo Immunotherapy (NIR-PIT), which has shown great potential in targeting tumors via a host immunogenic response, with already known and available anti-cancer immunomodulators to further enhance the antitumor response. The investigators have shown in mouse models that, when used in combination, NIR-PIT-treatment and standard antitumor agents conferred a potent vaccine-like effect, not only curing mice of local and distant cancers but successfully immunizing them against tumor regrowth.

Overexpression of Phf19 on T Cells Enhances Therapeutic Effects of T Cell-Based Therapies (such as Chimeric Antigen Receptor [CAR] Therapies)

Researchers at the National Cancer Institute (NCI) have developed a method to epigenetically reprogram CD8+ T cell fate by expressing elevated levels of the polycomb-like protein, Phf19. This technology is useful for improving T cell-based immunotherapies (such as CAR therapies) to treat a range of infectious diseases and cancers. NCI seeks licensing or co-development partners for this invention.

Monoclonal Antibodies and Immunoconjugates Directed to the Non-ShedPortion (“Stalk”) of Mesothelin are Excellent Candidates for Developing Therapeutic Agents

Antibodies that specifically recognize and bind to the unshed portion (“stalk”) of human mesothelin are strong therapeutic candidates because they maintain contact with the cancer cell for a longer duration than other anti-mesothelin antibodies that are currently available. The National Cancer Institute (NCI) has developed such antibodies that specifically recognize and bind to the stalk of human mesothelin with high affinity. The NCI seeks licensing and/or co-development research collaborations to advance the development and commercialization of these antibodies.

T cell Receptors Which Recognize Mutated EGFR

Researchers at the National Cancer Institute (NCI) have isolated T cell receptors (TCRs) that target specific mutations in the epidermal growth factor receptor (EGFR). The mutated protein recognized by these TCRs is frequently expressed in non-small cell lung cancer (NSCLC). These TCRs can be used for a variety of therapeutic applications, including engineered adoptive cell immunotherapy. Researchers at the NCI seek licensing and/or co-development research collaborations for these novel T cell receptors that recognize EGFR mutations.

Polymeric Delivery Platform for Therapeutics

The National Cancer Institute (NCI) seeks licensing and/or co-development research collaborations for a polymeric drug delivery platform that targets scavenger receptor A1 (SR-A1), a receptor highly expressed in macrophages, monocytes, mast cells, dendritic cells (myeloid lineages), and endothelial cells. The platform delivers various immunomodulatory therapeutic cargo including small molecule drugs, therapeutic peptides, and vaccines, to the lymphatic system and myeloid/antigen presenting cell (APC) sub-populations.

Potassium Hydroxy Citrate Promotes Longevity and Efficacy of Anti-Tumor T cells for Adoptive Cell Therapy (ACT)

Adoptive cell therapy (ACT) using tumor-specific T cells leads to complete tumor regression in some cancer patients. However, limiting the efficacy of this therapy is that T cells become functionally exhausted and have short half-lives after adoptive transfer. Researchers at the National Cancer Institute (NCI) have discovered a novel method to generate long-lived memory tumor-specific T cells with enhanced tumor clearance and persistence upon in vivo transfer. NCI is seeking parties interested in licensing and/or co-developing potassium hydroxy citrate to promote longevity and efficacy of tumor-specific T cells.

Small Molecule Inhibitors of Drug Resistant Forms of HIV-1 Integrase

Researchers at the National Cancer Institute discovered small-molecule compounds containing 1-hydroxy-2-oxo-1,8-naphthyridine moieties whose activity against HIV-1 integrase mutants confer resistance to currently approved INSTIs. Preliminary rodent efficacy, metabolic, and pharmacokinetic studies have been completed by the NCI researchers. The National Cancer Institute seeks partners to commercialize this class of compounds through licensing or co-development.
