­Overview
In recent years, immune checkpoint blockade (ICB) has provided oncologists with a powerful new tool. But while ICB has been found to be effective in microsatellite instability-high (MSI-H) colorectal cancer, it is far less effective in microsatellite stable (MSS) colorectal cancer. We have developed glycogen synthase kinase-beta (GSK-3-b) inhibitors that are effective in cases of MSS colorectal cancer.
 
Market Opportunity
Globally, among cancers, colorectal cancer ranks third in terms of incidence and second in terms of mortality. Treatment options include surgery, chemotherapy, radiation therapy, targeted therapy, and immunotherapy. ICB, developed in recent years, has been found to be effective in MSI-H colorectal cancer, but not in MSS colorectal cancer. Thus, there remains a need for treatment for the ~85 % of patients with MSS for whom ICB is not effective.

Innovation and Meaningful Advantages
We have demonstrated that inhibition of GSK3-b with the small molecule 9-ING-41 stimulates natural killer and T cell activity, reduces vascular endothelial growth factor levels, and induces colon cancer cell death. The immune modulatory effects of GSK3-b could also attenuate or block COVID-19 in patients with early or less severe infection.

Collaboration Opportunity
We are interested in exploring 1) startup opportunities with investors; 2) research collaborations with leading pharmaceutical companies to develop this method of treatment; and 3) licensing opportunities with companies.
