Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	1. The Company Bone Biologics Corporation (the “Company”) was incorporated under the laws of the State of Delaware on October 18, 2007 as AFH Acquisition X, Inc. Pursuant to a Merger Agreement, dated September 19, 2014, by and among the Company, its wholly-owned subsidiary, Bone Biologics Acquisition Corp., a Delaware corporation (“Merger Sub”), and Bone Biologics, Inc. Merger Sub merged with and into Bone Biologics Inc., with Bone Biologics Inc. remaining as the surviving corporation in the merger. Upon the consummation of the merger, the separate existence of Merger Sub ceased. On September 22, 2014, the Company officially changed its name to “Bone Biologics Corporation” to more accurately reflect the nature of its business and Bone Biologics, Inc. became a wholly owned subsidiary of the Company. Bone Biologics, Inc. was incorporated in California on September 9, 2004. On July 16, 2018, the Company closed a rights offering in which Hankey Capital purchased 3,539,654 shares of the Company’s Common Stock and executed amendments (the “Amendments”) to the convertible promissory notes (the “Existing Convertible Notes”) payable to Hankey Capital and dated October 24, 2014, May 4, 2015 and February 24, 2016. The Amendments reduced the conversion price of the Existing Convertible Notes from $15.80 per share to $1.00 per share and extended the maturity date of the February 24, 2016 convertible promissory note from February 24, 2019 to December 31, 2019. As a result of the share issuance and Amendments, Hankey Capital and Don Hankey, the Chairman of the Company’s Board of Directors, acquired a majority of the voting common shares issued and outstanding and thus effective control of the Company. We are a medical device company that is currently focused on bone regeneration in spinal fusion using the recombinant human protein, known as NELL-1/DBX®. The NELL-1/DBX® combination product is an osteostimulative recombinant protein that provides target specific control over bone regeneration. The protein, as part of the UCB-1 technology platform, has been licensed exclusively for worldwide applications to us through a technology transfer from UCLA Technology Development Group on behalf of UC Regents (“UCLA TDG”). UCLA TDG and the Company received guidance from the FDA that NELL-1/DBX® will be classified as a combination product with a device lead. We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, which we refer to as the JOBS Act. We would cease to be an emerging growth company upon the earliest of: (i) the last day of the first fiscal year in which our annual gross revenues are $1.07 billion or more; (ii) the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeded $700.0 million as of the end of the second quarter of that fiscal year; or (iii) the date on which we have, during the previous three-year period, issued more than $1.07 billion in non-convertible debt securities. An emerging growth company may take advantage of specified reduced reporting and other burdens that are otherwise applicable generally to public companies. We have elected to take advantage of these reduced disclosure obligations, and may elect to take advantage of other reduced reporting obligations in the future. The JOBS Act permits an emerging growth company like us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We are choosing to irrevocably “opt out” of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted. The production and marketing of the Company’s products and its ongoing research and development activities will be subject to extensive regulation by numerous governmental authorities in the United States. Prior to marketing in the United States, any combination product developed by the Company must undergo rigorous preclinical (animal) and clinical (human) testing and an extensive regulatory approval process implemented by the FDA under the Food, Drug and Cosmetic Act. There can be no assurance that the Company will not encounter problems in clinical trials that will cause the Company or the FDA to delay or suspend clinical trials. The Company’s success will depend in part on its ability to obtain patents and product license rights, maintain trade secrets, and operate without infringing on the proprietary rights of others, both in the United States and other countries. There can be no assurance that patents issued to or licensed by the Company will not be challenged, invalidated, or circumvented, or that the rights granted thereunder will provide proprietary protection or competitive advantages to the Company. *Going Concern and Liquidity* The Company has no significant operating history and since inception to March 31, 2019 has incurred accumulated losses of approximately $65.0 million. The Company will continue to incur significant expenses for development activities for their lead product NELL-1/DBX®. Operating expenditures for the next twelve months are estimated at $12.1 million. The accompanying consolidated financial statements for the period ended March 31, 2019 have been prepared assuming the Company will continue as a going concern. As reflected in the financial statements, the Company had a stockholders’ deficit of $9,971,690 at March 31, 2019, and incurred a net loss of $1,406,693, and used net cash in operating activities of $928,967 during the three months ended March 31, 2019. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. In addition, our independent accounting firm, in its audit report to the financial statements included in our Annual Report for the year ended December 31, 2018, expressed substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company will continue to attempt to raise additional debt and/or equity financing to fund future operations and to provide additional working capital. However, there is no assurance that such financing will be consummated or obtained in sufficient amounts necessary to meet the Company’s needs. If cash resources are insufficient to satisfy the Company’s on-going cash requirements, the Company will be required to scale back or discontinue its product development programs, or obtain funds if available (although there can be no certainties) through strategic alliances that may require the Company to relinquish rights to its technology, substantially reduce or discontinue its operations entirely. No assurance can be given that any future financing will be available or, if available, that it will be on terms that are satisfactory to the Company. Even if the Company is able to obtain additional financing, it may contain undue restrictions on our operations, in the case of debt financing, or cause substantial dilution for our stockholders, in the case of equity financing. For the past several years, we have depended on our relationship with Hankey Capital for working capital to fund our operations, which has been raised in the form of both debt and equity capital. Hankey Capital, directly and indirectly, controls approximately 88% of our issued and outstanding shares of common stock (including collateral shares) and has been issued convertible notes payable with an aggregate principal balance of $9,700,000 at March 31, 2019. Representatives of Hankey Capital also currently serve as directors of the Company. No assurance can be given that any future financing will be available or, if available, that it will be on terms that are satisfactory to the Company. Even if the Company is able to obtain additional financing, it may contain undue restrictions on our operations, in the case of debt financing, or cause substantial dilution for our stockholders, in the case of equity financing. At March 31, 2019, the Company had $1,300,000 available under a credit facility with Hankey Capital. Pursuant to the October 2016 Note Purchase Agreement, the Company’s management has agreed to defer 20% of earned compensation and the Board of Directors has authorized a change in director compensation to defer 50% of the directors’ cash compensation until at least $5,000,000 has been received in cumulative funding from non-current stockholders. *Reverse Stock Split* Effective July 24, 2018, the directors of the Company approved a resolution to undertake a reverse split of the common stock of the Company on a basis of 1 new common share for 10 old common share. All references in these financial statements to number of common shares, price per share and weighted average number of shares outstanding prior to the 1 for 10 reverse split have been adjusted to reflect the stock split on a retroactive basis as of the earliest period presented, unless otherwise noted.
