Moleculin Acquires Active Drug Compound for the Tr

HOUSTON, TX --(Marketwired - August 16, 2017) - Moleculin Biotech, Inc., ( NASDAQ : MBRX ) ("Moleculin" or the "Company"), a preclinical 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, today announced it has acquired WP1122 active drug compound it plans to study for the treatment of brain tumors.

Walter Klemp, CEO of Moleculin commented: "There has been a lot of excitement recently surrounding the WP1122 technology and its potential to become a new approach for treating brain tumors. We are pleased that we have now secured exclusive access to a significant quantity of GMP synthesized WP1122 drug substance from our sublicense partner in Poland."

"Access to this product allows us to accelerate preclinical toxicology and analytical testing of WP1122," Mr. Klemp continued, "which enables preparation of an Investigational New Drug application so we can begin proof of concept clinical trials. Research at MD Anderson using live human brain tumors transplanted into mice has shown that WP1122 has the potential to outperform the current standard of care treatment for glioblastoma, one of the most pervasive forms of brain tumors. We are eager to get this drug into human testing to determine if we have something that could make a real difference for patients."
