Nature of Business and Liquidity
The terms “MBI” or “the Company”, “we”, “our” and “us” are used herein to refer to Moleculin Biotech, Inc. MBI is a preclinical pharmaceutical company organized as a Delaware corporation in July 2015 to focus 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, which we refer to as MD Anderson.
Our lead drug candidate is liposomal Annamycin, which we refer to as Annamycin, an anthracycline being studied for the treatment of relapsed or refractory acute myeloid leukemia, or AML. In August 2015, the Company entered into a rights transfer agreement with AnnaMed, Inc. (“AnnaMed”), a company affiliated with certain members of the Company’s management and board of directors, pursuant to which, in exchange for 1,431,000 shares of the Company’s common stock, AnnaMed agreed to transfer to MBI any and all data it had regarding the development of Annamycin and the Annamycin investigative new drug application (“IND”) with the U.S. Food and Drug Administration (“FDA”) , including all trade secrets, know-how, confidential information and other intellectual property rights held by AnnaMed. Annamycin has been in clinical trials pursuant to an IND that had been filed with the FDA. This IND was terminated due to a lack of activity by a prior drug developer. However, in the course of our review of that data, we identified that Annamycin may have greater potential for efficacy than we originally believed, based on an unexpected potential opportunity to increase the drug’s Maximum Tolerable Dose (“MTD”). We determined to adjust our clinical strategy by adding in a Phase I arm to our next Phase II trial.
Because the prior developer of Annamycin allowed their IND to lapse, we are required to submit a new IND for continued clinical trials with Annamycin. We filed our IND application, with the clinical strategy of increasing the MTD mentioned above, for Annamycin on February 10, 2017.  In subsequent discussions with us, FDA requested certain revisions to the protocol, additional information, and additional data related to Chemistry, Manufacturing and Controls (“CMC”).  We have the additional information, have made the requested revisions to the protocol, and we are working on developing the CMC data.  In the interim, we have withdrawn the IND application in order to resubmit it when the requested data are available.  We believe that resubmission of the IND application will occur in time for the IND to go into effect and the announcement of the beginning of Phase I/II clinical trials in the first half of 2017. However, if we are unable to obtain the required CMC data on a timely basis, we will be delayed in resubmitting our IND application, which will delay the commencement of our clinical trials beyond the first half of 2017.
The Annamycin drug substance is no longer covered by any existing patent protection. We intend to submit patent applications for formulation, synthetic process and reconstitution related to our Annamycin drug product candidate, although there is no assurance that we will be successful in obtaining such patent protection. On March 21, 2017, we received notice that FDA had granted us Orphan Drug designation for Annamycin for the treatment of AML . Orphan Drug status could entitle us to market exclusivity of up to 7 and 10 years from the date of approval of a New Drug Application (“NDA”) or Marketing Authorization Application (“MAA”), in the US and the European Union (“EU”), respectively. Separately, the FDA may also grant market exclusivity of up to five years for newly approved new chemical entities (of which Annamycin would be one), but there can be no assurance that such exclusivity will be granted. 
We have two other drug development projects in progress, one involving a portfolio of small molecules, which we refer to as the WP1066 Portfolio, focused on the modulation of key oncogenic transcription factors involved in the progression of cancer, and the WP1122 Portfolio, a suite of molecules targeting the metabolic processes involved in cancer in general, and glioblastoma (the most common form of brain tumor) in particular. We have been granted royalty-bearing, worldwide, exclusive licenses for the patent and technology rights related to our WP1066 Portfolio and WP1122 Portfolio drug technologies, as these patent rights are owned by MD Anderson.  
On August 11, 2015, the Company entered into a rights transfer agreement for WP1122 with IntertechBio Corporation (“IntertechBio”), a company affiliated with certain members of our management, whereby IntertechBio agreed to assign its license or sublicense its license   to certain metabolic inhibitor technology owned by MD Anderson. In consideration, the Company issued 630,000 common shares to IntertechBio. IntertechBio   agreed to make payments to MD Anderson including an up-front payment, license documentation fee, annual maintenance fee, milestone payments and minimum annual royalty payments for sales of products developed under the license agreement. The Company has assumed the rights and obligations of IntertechBio under the license agreement with MD Anderson. Therefore,  all out-of-pocket expenses incurred by MD Anderson in filing, prosecuting and maintaining the licensed patents have been and shall continue to be assumed   by the Company.
In accordance with FASB ASC Topic 280, Segment Reporting, we view our operations and manage our business as principally one segment. As a result, the financial information disclosed herein represents all of the material financial information related to our principal operating segment. 
The Company filed a registration statement on Form S-1 (which was declared effective on May 2, 2016) with respect to the Company’s initial public offering of shares of its common stock (“IPO”) to fund the development of its technologies. Prior to the declaration of effectiveness of the registration statement on Form S-1, we acquired Moleculin, LLC which was merged with and into MBI. Moleculin, LLC was the holder of a license agreement with MD Anderson covering technology referred to as   the WP1066 Portfolio, which is focused on the modulation of key oncogenic transcription factors.
