Moleculin Announces New Data Further Supporting Its Lead Drug for Treating Pancreatic Cancer

WP1732 shown to accumulate beneficially in pancreas


HOUSTON – November 28, 2018 – Moleculin Biotech, Inc., (Nasdaq: MBRX) (“Moleculin” or the “Company”), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced that data from an independent test in animal models confirmed, as previously believed, that its immuno-stimulating STAT3 inhibitor achieves disproportionately high accumulation in the pancreas.


“Our own sponsored research suggested that WP1732 might be an ideal candidate for treating pancreatic cancer,” commented Dr. Donald Picker, Moleculin’s Chief Science Officer.  “Now, we have independent testing with radiolabeled drug confirming this in animal models.  The propensity for such enhanced pancreatic  distribution could be highly beneficial for a new pancreatic cancer drug.”


Walter Klemp, Moleculin’s Chairman and CEO added, “Published research shows that the growth and survival of pancreatic cancer requires activated STAT3 (p-STAT3) and our own research suggests that WP1732 may be one of the most effective inhibitors of p-STAT3 that has demonstrated activity in in vivo models.  Confirming the disproportionately high accumumulation of WP1732 in the pancreas puts us one step closer to introducing an entirely new approach to treating pancreatic cancer.  This is very encouraging and confirms the direction that Moleculin has taken with WP1732. We are heavily engaged in preparing the data necessary for an Investigational New Drug (IND) application with the FDA which we are targeted to file in 2019.”
