In preclinical testing, G-202 was shown to ablate tumors in animal models of breast cancer, prostate cancer and kidney cancer. GenSpera, Inc. owns and controls all rights to G-202 and anticipates a strategic partnership to maximize the value of the drug as it progresses through future clinical trials.
