Moleculin Biotech Reports Financial Results For The First Quarter Ended March 31, 2017

HOUSTON, TX--(Marketwired - May 15, 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 M.D. Anderson Cancer Center (“MD Anderson”), today announced its financial and operating results for the first quarter ended March 31, 2017 and other recent developments.

First Quarter & Recent Highlights

Annamycin

• Appointed Theradex Systems, Inc. as its contract research organization (“CRO”) for its planned Phase I/II clinical trial for Annamycin for the treatment of relapsed or refractory acute myeloid leukemia (“AML”).
• Received Orphan Drug Designation by the U.S. Food and Drug Administration (“FDA”) for the treatment of AML. The FDA grants orphan drug designation to drugs and biologics that are intended for the treatment of rare diseases that affect fewer than 200,000 people in the U.S. Orphan drug status is intended to facilitate drug development for rare diseases and may provide several benefits to drug developers, including tax credits for qualified clinical trial costs, exemptions from certain FDA application fees, and seven years of market exclusivity upon regulatory product approval.
• Recently filed the IND application for Annamycin, with a Phase I/II approach with the intent of increasing the Maximum Tolerable Dose (“MTD”). In subsequent discussions, the FDA requested certain revisions to the protocol, additional information, and additional data related to Chemistry, Manufacturing and Controls (“CMC”). The Company has the additional information, has made the requested revisions to the protocol, and is working on developing the CMC data. In the interim, Moleculin has withdrawn the IND application in order to resubmit it when the requested data are available. The Company believes that the resubmission of the IND application will occur in time for the IND to go into effect prior to the end of July 2017 and allow for clinical trials. However, if the Company is unable to obtain the required CMC data on a timely basis, it will be delayed in resubmitting its IND application, which will delay the commencement of the clinical trials for Annamycin beyond July 2017.
• Updated the Annamycin clinical strategy to add a Phase I arm to its next Phase II trial that leverages a potential increase in the MTD, which could increase the chance for positive outcomes. The Company believes that it will be able to publicly announce results from its Phase I/II clinical trial sometime in 2018.

WP1066

• An MD Anderson physician is sponsoring a study of WP1066 for the treatment of brain tumors. While the Company is not participating in and has no influence on the conduct of this study, we understand that the sponsoring physician has submitted an IND to the FDA and the IND is on hold until documentation of Good Manufacturing Process or GMP production of WP1066 can be presented to the FDA, which Moleculin has agreed to provide. The Company expects that the sponsor’s IND will move forward in 2017 and may produce publishable clinical results in 2018.
• Physician-scientists at another major US cancer center have requested and Moleculin has agreed to supply them with WP1066 for testing in a potential grant-funded clinical trial for children with Diffuse Intrinsic Pontine Gliomas (DIPG), a rare and very aggressive form of brain tumor. Studies conducted at this center have suggested that DIPG may be particularly sensitive to the inhibition of the activated form of a cell-signaling protein called STAT3, a primary target of WP1066, and their studies have demonstrated significant anti-tumor activity of WP1066 in DIPG in vitro and in vivo tumor models.

Corporate

• Announced the closing of an underwritten public offering of securities for net proceeds of approximately $4.5 million. Roth Capital Partners and National Securities Corporation acted as joint book-running managers. Subsequently, approximately $0.8 million of additional funds have been received through the exercise of associated warrants issued in the offering bringing the total net raised in excess of $5 million.
• Announced that Drs. Sandra Silberman and Paul Waymack have joined the Company’s Scientific Advisory Board (“SAB”). The Company’s current SAB also includes Dr. Waldemar Priebe (Chair) and Dr. Madeleine Duvic.
