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

CD19 and CD20 are promising targets for the treatment of B-Cell malignancies.  Unfortunately, some clinical studies have shown that there is a loss of CD19 or CD20 expression in various cases of lymphomas and leukemias, particularly after treatment with an agent that targets CD19 (e.g., anti-CD19 CAR-T). However, studies have shown that expression of one protein is retained when the other is lost. This suggests that a therapeutic with the ability to simultaneously target both CD19 and CD20 could represent a solution to the drawbacks of current therapies. 

High Affinity Monoclonal Antibodies Targeting Glypican-1

Pancreatic cancer is the fourth most common cause of death from cancer in the U.S. The overall 5-year survival rate for this disease is 8.5%. Glypican-1 (GPC1), a cell surface heparan sulfate proteoglycan protein that is overexpressed in pancreatic cancer. Due to this preferential expression, GPC1 represents a potential candidate for targeted therapy for patients with pancreatic cancer and other GPC1 expressing cancers such as prostate cancer.

New Chimeric Antigen Receptor (CAR) Format for Developing Improved Adoptive Cell Therapies

Adoptive cell therapy (ACT) is an attractive new therapeutic approach for treating various cancers. ACT has recently demonstrated a high degree of efficacy when treating patients with hematological malignancies. However, to date, no effective Chimeric Antigen Receptors (CAR) T cell therapy exists for solid tumors.

High-Affinity Rabbit Monoclonal Antibodies for Cancer Treatment

Mesothelin is a cell surface protein that is highly expressed in aggressive cancers, such as malignant mesothelioma, ovarian cancer and pancreatic cancer, lung cancer, breast cancer, cholangiocarcinoma, bile duct carcinoma and gastric cancer.  Because of this selective expression, mesothelin is an excellent candidate for targeted therapeutics, such as monoclonal antibodies (mAbs) and chimeric molecules.  Current anti-mesothelin therapeutic mAb candidates bind to an epitope in Region I of mesothelin.  Unfortunately, Region I contains the interaction site MUC16/CA125, a mesothe

IgG4 Hinge Containing Chimeric Antigen Receptors Targeting Glypican-1 For Treating Solid Tumors

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) for Treating Lymphoma and Other Cancers

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).

Combination of recombinant IL-7 with Chimeric Antigen Receptor (CAR) T Cells Targeting Glypican-3 (GPC3) for the Treatment of Hepatocellular Carcinoma (HCC)

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. 

Improved PE-based Targeted Toxins: A Therapeutic with Increased Effectiveness

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.
