Moleculin Announces Breakthrough Discovery for its WP1066
WP1066 shown to counteract resistance to checkpoint blockades
HOUSTON, Dec. 04, 2018 (GLOBE NEWSWIRE) -- 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 its own sponsored research has now confirmed a recent published study demonstrating the ability of its clinical-stage immuno-stimulating STAT3 inhibitor, WP1066, to inhibit a key immune checkpoint target known as PD-L1.
“We have known for some time that WP1066 had the potential to stimulate a natural immune response,” commented Dr. Donald Picker, Moleculin’s Chief Science Officer. “But, this data suggests that our drug may be capable of having a major impact on the field of checkpoint blockades. With this information combined with findings from other recently published studies demonstrating the impotant role of STAT3 in cancer immunology, we plan to run additional in vitro and in vivo studies, some of which are already underway, with WP1066 in combination with well-known checkpoint inhibitors to gather more data on this response.”
Walter Klemp, Moleculin’s Chairman and CEO added, “This potential was initially reported in a 2017 Japanese study (Journal of clinical and experimental hematopathology, Vol. 57 No.1, 21-25, 2017), but we have now been able to confirm this activity with our own sponsored research at MD Anderson. Also, very recent independent research (Front Pharmacol. 2018 May 22;9:536. doi: 10.3389/fphar.2018.00536. eCollection 2018.) has linked STAT3, HIF1-a and c-Myc (all targets of WP1066) to the mechanism (a ligand known as PD-L1) believed to be largely responsible for resistance to current checkpoint blockade therapies. We believe this could put WP1066 center-stage in the field of immunotherapy. It’s potentially a tremendous breakthrough for our company.”
