Pancreatic cancer is the fourth most common cause of cancer deaths in the U.S. The overall 5-year survival rate is 8.5%. Glypican-1 (GPC1) is a cell surface heparan sulfate proteoglycan protein overexpressed in pancreatic cancer. Due to preferential expression, GPC1 represents a potential candidate for targeted therapy for pancreatic cancer and other GPC1-expressing cancers, such as prostate.
Chimeric antigen receptors (CARs) are hybrid proteins that consist of two major components: a targeting domain and a signaling domain. The targeting domain allows T cells which express the CAR to selectively recognize and bind to diseased cells that express a particular protein. Once the diseased cell is bound by the targeting domain of the CAR, the signaling domain of the CAR activates the T cell, thereby allowing it to kill the diseased cell. This is a promising new therapeutic approach known as adoptive cell therapy (ACT).
Hepatocellular carcinoma (HCC) is the most common type of liver cancer. standard treatment for HCC is not suitable for a large proportion of liver cancer patients. As a result, alternative treatments are needed. Chimeric antigen receptor (CAR) T cell therapy is a promising alternative approach selectively targets targeting tumors via tumor-specific antigens. However, to date, no effective CAR T cell therapy exists for HCC.
The National Cancer Institute seeks parties interested in collaborative research to further co-develop monoclonal antibodies for the treatment of mesothelin-expressing cancers. The antibody was able to inhibit tumor growth in mouse xenograft models, and corresponding immunotoxins were able to inhibit tumor cell growth in vitro
Targeted toxins (e.g., immunotoxins) are therapeutics that have at least two important components: (1) a toxin domain that is capable of killing cells and (2) a targeting domain that is capable of selectively localizing the toxic domain to only those cells which should be killed. By selecting a targeting domain that binds only to certain diseased cells (e.g., a cell which only expresses a cell surface receptor when in a diseased state), targeted toxins can kill the diseased cells while allowing healthy, essential cells to survive.
Neuroblastoma is a rare pediatric cancer with approximately 1,000 new cases arising annually. Current therapies have a less than forty-five percent (45%), three-year survival rate which demonstrate a need for a more effective treatment against this disease. Glypican-2 (GPC2) is a cell surface protein that is preferentially expressed in pediatric cancers including neuroblastoma, which makes GPC2 an attractive candidate for targeted therapy.
Neuroblastoma is a rare pediatric cancer that affects one in every hundred thousand children under the age of fifteen in the United States. Current standards of care are chemotherapy and surgery, followed by stem-cell treatments, radiation and anti-ganglioside antibody therapy, which yield an average three-year survival rate of 10-45%. This demonstrates a need for more effective therapies.
The National Cancer Institute (NCI) seeks parties to license software for modeling the targeted delivery of anti-cancer agents in solid tumors.
The software models the permeability and concentration of intravenously administered antibody anti-cancer agent conjugates in solid tumors. The models can be used to determine optimal dosing regimen of a therapeutic in a particular cancer type. Thirty factors that affect delivery rates and efficiencies are analyzed as variables in generating the models.
Bacterial spores can be modified to display molecules of interest, including drugs, immunogenic peptides, antibodies and other functional proteins of interest (such as enzymes). The resulting engineered bacterial spores can provide many useful functions such as the treatment of infections, use as an adjuvant for the delivery of vaccines, and the enzymatic degradation of environmental pollutants.
CD276 (also called B7-H3) is a pan-cancer antigen expressed in multiple solid tumors and an emerging cancer target. CD276 protein is overexpressed in pancreatic cancer, prostate cancer, breast cancer, colon cancer, lung cancer, and brain tumors (such as neuroblastoma) – making it an ideal target for cancer therapy.
Investigators at the National Cancer Institute (NCI) have isolated a panel of anti-CD276 single domain antibodies (also known as nanobodies) from novel camel and rabbit single domain (VHH) libraries by phage display.
