SAN DIEGO, March 21, 2017 /PRNewswire/ -- Tarrex Biopharma, Inc. today announced that the U.S. Food and Drug Administration

(FDA) has accepted the Company's Investigational New Drug (IND) application for TX803, a novel treatment for colorectal cancer. "This marks the first significant milestone for Tarrex in our efforts to develop innovative cancer therapeutics to address
unmet medical needs and we are very excited that we will be able to start testing TX803 in advanced colorectal cancer patients," said Kanyin E. Zhang, Ph.D. CEO of Tarrex.

TX803 is a first-in-class small molecule therapeutic that inhibits the PI3K/AKT pathway through a novel mechanism – by targeting, not the kinase itself, but a PI3K activating onco-protein, the truncated retinoid X receptor alfa (tRXR?). Moreover, tRXR? is found in high levels in tumor tissues obtained from a significant portion of colorectal, gastric and breast cancer patients. Preclinical studies have demonstrated that TX803 is orally bioavailable, well tolerated, and efficacious in several animal tumor models including KRAS mutated colorectal cancer. Tarrex has licensed the worldwide rights of TX803 and related intellectual properties from the Sanford Burnham Prebys Medical Discovery Institute in San Diego, California.

"Approximately 50% of colorectal cancer patients have tumors with a KRAS or NRAS mutation, which renders them resistant to anti-EGFR therapies, such as cetuximab and panitumumab. If clinically proven, TX803 has the potential to address a significant unmet need in treating RAS mutated colorectal and possibly other type of cancers," said Dr. Kimmie Ng, MD, MPH, Director of Clinical Research, Center for Gastrointestinal Oncology at Dana Farber Cancer Institute, Harvard Medical School, and Principal Investigator for TX803 clinical trials.
