Optimized Monospecific or Bicistronic Chimeric Antigen Receptor (CAR) Constructs Targeting CD19 and CD20

Researchers at the National Cancer Institute (NCI) developed improved monospecific and bicistronic chimeric antigen receptors (CARs) targeting CD19 and CD20. Importantly, CD19 and CD20 are highly expressed in diffuse large B-cell lymphoma, acute lymphoblastic leukemia and other B-cell lymphomas. These improved CARs can be useful in treating these diseases. NCI is seeking parties interested in the co-development or licensing of this invention for immunotherapy.

High Affinity Nanobodies Targeting B7-H3 (CD276) for Treating Solid Tumors

Researchers at the National Cancer Institute (NCI) have isolated a panel of anti-CD276 (also called B7-H3) single domain antibodies (also known as nanobodies). These antibodies have a high affinity for CD276-positive tumor cells and have great potential for diagnostic and therapeutic technologies against solid tumors. The NCI seeks licensing and/or co-development research collaborations for CD276-targeting camel nanobodies.

T-cell Receptors Targeting CD20-Positive Lymphomas and Leukemias

The National Cancer Institute (NCI) seeks licensees for a collection of T-cell receptors (TCRs) that specifically target the CD20 antigen expressed in B-lymphoid malignancies such as non-Hodgkin’s lymphoma (NHL), chronic lymphocytic leukemia, and acute lymphoblastic leukemia. The TCRs are being developed as therapeutics for the treatment of lymphomas and leukemias.

Anti-SLAMF7 Chimeric Antigen Receptors

Chimeric Antigen Receptor T cell (CAR-T) therapies that specifically target Signaling Lymphocyte Activation Molecule F7 (SLAMF7) are strong therapeutic candidates for patients with Multiple Myeloma (MM). SLAMF7 is highly expressed on the malignant plasma cells that constitute MM. The expression of SLAMF7 by MM cells and lack of expression on nonhematologic cells makes SLAMF7 an attractive therapeutic target for MM. Researchers at the National Cancer Institute (NCI) have invented anti- SLAMF7 CAR constructs that allow genetically-modified T cells to express both the anti-SLAMF7 antibody and a suicide gene that allows T cells to specifically recognize and kill SLAMF7-expressing cells as well as allow for on-demand and reliable elimination of anti-SLAMF7 CAR T cells. NCI seeks licensing and/or co-development partners for this invention.

Inhibition of T Cell Differentiation and Senescence by Overexpression of Transcription Factor c-Myb

Researchers at the National Cancer Institute (NCI) have developed a method by which memory T cells can be generated from other T cell populations using overexpression of the transcription factor c-Myb. Importantly, these reprogrammed memory T cells show increased proliferative and survival capacity. This strategy could also potentially generate anti-tumor T cells with improved viability and therapeutic efficacy for adoptive ACT. Researchers at the NCI seek licensing and/or co-development research collaborations for this invention.

Methods of Producing Effective T-cell Populations Using Akt Inhibitors

Adoptive cell therapy uses cancer reactive T-cells to effectively treat cancer patients. Producing many persistent T-cells is critical for successful treatments. Researchers at the NCI seek licensing and/or co-development research collaborations for a novel method of producing effective T-cell populations using Akt inhibitors.

A Rapid Method of Isolating Neoantigen-specific T Cell Receptor Sequences

Recent research has demonstrated that neoantigen-specific T-cell receptors (TCRs) can be isolated from a cancer patient’s lymphocytes. These TCRs may be used to engineer populations of tumor-reactive T cells for cancer immunotherapies. Obtaining sequences of these functional TCRs is a critical initial step in preparing this type of personalized cancer treatment; however, current methods are time-consuming and labor-intensive. Scientists at the National Cancer Institute (NCI) have developed a rapid and robust method of isolating the sequences of mutation-specific TCRs to alleviate these issues; they seek licensing and/or co-development research collaborations for the development of a method for isolating the sequences of tumor-reactive TCRs. For collaboration opportunities, please contact Steven A. Rosenberg, M.D., Ph.D. at sar@nih.gov.

Chimeric Antigen Receptors that Recognize Mesothelin for Cancer Immunotherapy

Researchers at the NCI have developed chimeric antigen receptors (CARs) with a high affinity for mesothelin to be used as an immunotherapy to treat pancreatic cancer, ovarian cancer, and mesothelioma. Cells that express CARs, most notably T cells, are highly reactive against their specific tumor antigen in an MHC-unrestricted manner to generate an immune response that promotes robust tumor cell elimination when infused into cancer patients.

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.

Cancer-reactive T cells from Peripheral Blood

T-cells capable of reacting to mutations in cancer patients have potential use as therapeutics. Identifying and isolating these cells from patients is a crucial step in developing these treatments. Researchers at the National Cancer Institute (NCI) have developed a novel method of isolating mutation-reactive T-cells from a patient’s peripheral blood lymphocytes (PBL). The NCI, Surgery Branch, is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize this method of isolating mutation-reactive T-cells from peripheral blood.

Methods for Producing Stem Cell-Like Memory T Cells for Use in T Cell-Based Immunotherapies
