1. ORGANIZATION AND BUSINESS Organization and Nature of Operations. RegeneRx Biopharmaceuticals, Inc. (RegeneRx, the Company, We, Us, Our), a Delaware corporation, was incorporated in 1982. We are focused on the discovery and development of novel molecules to accelerate tissue and organ repair. Our operations are confined to one business segment: the development and marketing of product candidates based on Thymosin Beta 4 (T4), an amino acid peptide. Management Plans to Address Operating Conditions. Our strategy is aimed at being capital efficient while leveraging our portfolio of clinical assets by seeking strategic relationships with organizations with clinical development capabilities including development capital. Currently, we have active partnerships in four major territories: North America, Europe, China and Pan Asia. In each case, the cost of development is being borne by our partners with no financial obligation for RegeneRx. We still have significant clinical assets to develop, primarily RGN-352 (injectable formulation of T4 for cardiac and CNS disorders) in the U.S., Pan Asia, and Europe, and RGN-259 in the EU. Our goal is to wait until satisfactory results are obtained from the current ophthalmic clinical program in the U.S. before moving into the EU. However, we intend to continue to develop RGN-352, our injectable systemic product candidate for cardiac and central nervous system indications, either by obtaining grants to fund a Phase 2a clinical trial in the cardiovascular or central nervous system fields or finding a suitable partner with the resources and capabilities to develop it as we have with RGN-259. Since inception, and through December 31, 2019, we have an accumulated deficit of $107 million and we had cash and cash equivalents of $639,916 as of December 31, 2019. We anticipate incurring additional operating losses in the future as we continue to explore the potential clinical benefits of T4-based product candidates over multiple indications. We have entered into a series of strategic partnerships under licensing and joint venture agreements where our partners are responsible for advancing development of our product candidates by sponsoring multiple clinical trials. In February 2019, we sold a series of convertible promissory notes to management, the Companys Board of Directors and accredited investors including Essetifin S.p.A., our largest stockholder (the "2019 Notes"). The sale of the 2019 Notes resulted in gross proceeds to the Company of $1,300,000 over two closings. The first closing in the amount of $650,000 occurred in February 2019 and the second closing, also in the amount of $650,000 , occurred on May 13, 2019 after the Company provided notice of the enrollment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. The 2019 Notes contain a $0.12 conversion price and the purchasers also received a warrant exercisable at $0.18 to purchase additional shares of common stock equal to 75% of the number of shares into which each note is initially convertible (the "2019 Warrants"). In addition, we received proceeds of $115,625 pursuant to the exercise of warrants held by Sabby Management as well as $125,000 for April 2019 warrant exercises. In January 2020, Sabby exercised their remaining warrants and the Company received proceeds of $241,912. At present, with the receipt of the proceeds the January 2020 warrant exercises, we will have sufficient cash to fund planned operations through the third quarter of 2020. While we successfully secured additional operating capital to continue operations through the third quarter of 2020, we will need substantial additional funds in order to significantly advance development of our unlicensed programs. Accordingly, we will continue to evaluate opportunities to raise additional capital and are in the process of exploring various alternatives, including, without limitation, a public or private placement of our securities, debt financing, corporate collaboration and licensing arrangements, or the sale of our Company or certain of our intellectual property rights. These factors raise substantial doubt about our ability to continue as a going concern. The accompanying financial statements have been prepared assuming that we will continue as a going concern. This basis of accounting contemplates the recovery of our assets and the satisfaction of our liabilities in the normal course of business. Although we intend to continue to seek additional financing or additional strategic partners, we may not be able to complete a financing or corporate transaction, either on favorable terms or at all. If we are unable to complete a financing or strategic transaction, we may not be able to continue as a going concern after our funds have been exhausted, and we could be required to significantly curtail or cease operations, file for bankruptcy or liquidate and dissolve. There can be no assurance that we will be able to obtain any sources of funding. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should we be forced to take any such actions. In addition to our current operational requirements, we continually refine our operating strategy and evaluate alternative clinical uses of T4. However, substantial additional resources will be needed before we will be able to achieve sustained profitability. Consequently, we continually evaluate alternative sources of financing such as the sharing of development costs through strategic collaboration agreements. There can be no assurance that our financing efforts will be successful and, if we are not able to obtain sufficient levels of financing, we would delay certain clinical and/or research activities and our financial condition would be materially and adversely affected. Even if we are able to obtain sufficient funding, other factors including competition, dependence on third parties, uncertainty regarding patents, protection of proprietary rights, manufacturing of peptides, and technology obsolescence could have a significant impact on us and our operations. To achieve profitability, we, and/or a partner, must successfully conduct pre-clinical studies and clinical trials, obtain required regulatory approvals and successfully manufacture and market those pharmaceuticals we wish to commercialize. The time required to reach profitability is highly uncertain, and there can be no assurance that we will be able to achieve sustained profitability, if at all.
