This technology includes monoclonal antibodies (mAb) that specifically and with high affinity bind the final complement components C3dg and C3d (subsequently referred to as C3d), which can be used to kill tumor cells that carry C3d on their cell surface. We show that tumor cells of patients treated with the therapeutic anti-CD20 mAb ofatumumab carry C3d on the cell surface and can bind and be killed by addition of anti-C3 mAbs. In contrast, further addition of more ofatumumab has only minimal effects.

This technology includes a new chemical scaffold (with lead compound XL5) against hRpn13 that induces apoptosis, which may have clinical efficacy against cancer. The structure of XL5-conjugated hRpn13 guided the design of XL5-PROTAC degrader compounds that exhibit greater efficacy than previous hRpn13-targeting compounds, as evaluated by selectivity for hRpn13, induction of apoptosis, and loss of cell viability. In cells, XL5-PROTACs revealed the presence of a truncated hRpn13 product that binds to proteasomes and is selectively degraded by XL5-PROTACs.

Summary:

The National Cancer Institute (NCI) seeks research co-development partners and/or licensees for three small molecules that target hRpn13, an overexpressed protein in certain cancers.

Description of Technology:

Human papillomavirus (HPV) has been associated with the cause of several cancer types, including cervical, anal, and head and neck cancers. There has been great success in preventing HPV infections with the development of prophylactic HPV vaccines, Gardasil and Cervarix. However, these vaccines have only been shown to prevent HPV infection and not treat those already infected with HPV. These vaccines elicit antibody responses to late HPV genes, and thus would not be effective in treating established tumors.

Tumor invasion and metastasis are the primary drivers of cancer-related mortality. Therapies that have an ability to specifically target invasive and/or metastatic cells are anticipated to have a significant impact in the clinical management of advanced cancers.

Bladder cancer is the fifth most common cancer in the United States and one of the costliest cancers to treat. Compared to other cancer types, bladder cancer has been understudied, and there is a need for informative mouse bladder cancer models that resemble the clinical situation and allow for evaluation of chemotherapeutic or immunotherapeutic agents. The orthotopic murine bladder cancer model MB49 resembles non-muscle invasive, nonmetastatic urothelial carcinomas and provides an opportunity to study the anti-tumor effects of immune cell checkpoint inhibitors.

This technology includes anti-PSMA antibody labeled with 177Lu, which has shown to be an effective treatment for prostate cancer. Several small molecules targeting PSMA were also evaluated in prostate cancer patients labeled with betta emitters such as 177Lu. The most common one is 177Lu-PSMA-617 which is under clinical evaluation in many countries. Usual treatment in patients in most clinical trials was composed of up to 3 cycles of 177Lu-PSMA-617.

HMGN polypeptides belong to the high mobility group (HMG) family of chromosomal binding peptides. HMGN polypeptides typically function inside the cell nucleus to bind to DNA and nucleosomes and regulate the transcription of various genes. HMGN polypeptides also can be released by peripheral blood mononuclear cells. However, the extracellular release of a HMGN polypeptide initiates activation of the immune system. Therefore, it has potential use as a biological therapeutic for stimulating an immune response.

Summary:

The National Cancer Institute (NCI) seeks co-development partners and/or licensees to further develop a novel ELISA-based biodosimeter.

Summary:

The National Cancer Institute (NCI) seeks licensees for the further development of a family of novel iodonium analogs as therapeutics for cancer and/or chronic inflammatory conditions.
