Turning cancer targets into breakthrough therapies

Our Mission

GO Therapeutics solves the key challenge of tumor-specificity to bring more targeted immunotherapy to cancer patients.

The Challenge of Cancer Immunotherapy

A new generation of cancer immunotherapy promise to change the paradigm of cancer treatment. Increasingly sophisticated modified T-cell based therapies and Antibody-Drug Conjugates (ADCs) show great promise to attack and destroy a patient’s cancer. But the primary challenge to getting these powerful new approaches to work is defining the cancer-specificity of the therapeutic. Simply, if the target that these therapies address happen to exist somewhere else in the body (other than on the surface of the tumor cells), or if there is cross-reactivity, then the patient will get sick or possibly die due to destruction of healthy tissue.

It is well established that tumors cells have aberrant glycosylation that are high potential cancer-specific therapeutic sites. However, the ability to identify and recreate these aberrant glycosylations ex-vivo for therapeutic antibody development has been the dream of many cancer researchers.

Until now.

About GO Therapeutics

GO Therapeutics is the only company with the technologies, platforms and know-how to harness the power of the cancer glycoproteome to generate exceptionally tumor-specific antibodies for cancer immunotherapies. By making antibodies to hybrid antigens combining a tumor’s up-regulated protein expression with a protein’s aberrant glycosylation pattern, we are able to dramatically increase tumor specificity. Our technology clears the hurdles for making drugs that are extremely specific to the cancer cell.

We have applied our breakthrough platforms to develop an extensive library of cancer-specific targets across major cancers. GO Therapeutics is currently developing a number of major targets and anticipates validated antibody drug candidates in a short timeframe.

Platform

A well understood characteristic of cancer is the aberrant glycosylation pattern of both proteins and lipids. It is these aberrant glycosylations that offer high potential to be immunologic epitopes for targeted immunotherapy.

Among the most characteristic and widespread of these truncated carbohydrate epitopes, particularly in epithelial cell cancers, is O-linked glycosylations. For example, research has shown that O-linked glycosylation is correlated with poor prognosis and lower survival rates for breast cancers and other aggressive tumors.

GO Therapeutics has developed a ground-breaking scientific platform to identify sites of O-linked glycosylation on tumor-associated proteins. We use the accessibility of these O-glycans at the plasma membrane to develop novel “hybrid” epitopes that are part protein and O-glycan structure. These hybrid epitopes are exquisite targets for immunotherapeutics.
