Summary

This clinical research study is being done to answer questions about how to treat cancer.

To clear cancer cells from the body, the immune system needs the action of proteins called Type 1 interferons. The protein STING (for STimulator of INterferon Genes) stimulates the body to make Type 1 interferons. Type 1 interferons activate key molecules in cancer immunity to kill cancer cells.

CRD3874 is a synthetic drug that activates STING, and STING stimulates the immune system to kill cancer cells. In experiments on blood from humans, CRD3874 makes blood cells produce molecules responsible for anti-cancer activity. CRD3874 was tested in mice with cancers including leukemia, head and neck cancer, lung cancer, pancreatic cancer and sarcoma. In these mice, CRD3874 made tumors shrink or disappear, and some mice developed long-lasting immunity against cancer. Also, when CRD3874 was given with other anti-cancer treatments, it increased their anti-cancer effects.
