Moleculin Announces Activity with Pancreatic Cance

HOUSTON, TX --(Marketwired - February 07, 2018) - Moleculin Biotech, Inc., ( NASDAQ : MBRX ) ("Moleculin" or the "Company"), a clinical stage pharmaceutical company focused on the development of anti-cancer drug candidates, some of which are based on license agreements with The University of Texas System on behalf of the MD Anderson Cancer Center ("MD Anderson"), today announced it has been able to show promising tumor suppression activity with its inhibitor of glycolysis, WP1122.

"We have previously announced that our glycolysis inhibitors have shown a remarkable affinity for concentrating in the pancreas," commented Walter Klemp, Chairman and CEO of Moleculin. "And, we know that pancreatic cancer is highly glycolytic. Now, we have solid data showing the ability of WP1122 to inhibit pancreatic tumor growth in mice."

Mr. Klemp continued, "This is the indicator we were looking for to support our going after pancreatic cancer as a primary target for the WP1122 portfolio. We couldn't be more excited given the intense unmet need in pancreatic cancer."
