NATURE OF OPERATIONS AND GOING CONCERN, BASIS OF PRESENTATION AND RECENT ACCOUNTING PRONOUNCEMENTS
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”) consistent with those applied in, and should be read in conjunction with, the Company’s audited consolidated financial statements and related footnotes for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K as filed with the United States Securities and Exchange Commission (“SEC”) on March 1, 2023. The unaudited consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the Company’s financial position as of September 30, 2023 and its results of operations and cash flows for the interim periods presented, and are not necessarily indicative of results for subsequent interim periods or for the full year. The interim consolidated financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements, as allowed by the relevant SEC rules and regulations; however, the Company believes that its disclosures are adequate to ensure that the information presented is not misleading. Certain reclassifications have been made to the prior year financial statements to conform to the presentation used in the current year. In the current year the Company reclassified certain current accrued expenses to Other liabilities on the Consolidated Balance Sheets. These reclassifications did not have an impact on total assets or total liabilities of the Consolidated Balance Sheets or cash flows as previously reported.
Going Concern	Going Concern The Company’s consolidated financial statements as of September 30, 2023 were prepared under the assumption that the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. However, as of September 30, 2023, substantial doubt exists about the Company’s ability to continue as a going concern. Since its inception, the Company has suffered recurring losses and negative cash flows from operations and will need additional funding to continue as a going concern. As of September 30, 2023, the Company had unrestricted cash and cash equivalents of $8.6 million, working capital of $8.9 million and the Company has recorded a net loss of $7.0 million during the nine months ended September 30, 2023. The Company will require additional liquidity to continue operations beyond the next 6 months. Given a variety of external factors including the impact of the recent economic downturn in the U.S. and global financial markets, the Company may be unable to access further equity or debt financing when needed. Lack of necessary funds may require the Company to, among other things, delay, scale back or eliminate some or all of its research and product development programs, and capital expenditures. The Company may alternatively engage in cost-cutting measures in an attempt to extend its cash resources as long as possible. As such, there can be no assurance that the Company will be able to obtain additional liquidity when needed or under acceptable terms, if at all. There is no assurance, moreover, that any funds raised will be sufficient to enable the Company to continue as a going concern. The Company’s consolidated financial statements as of September 30, 2023, do not include any adjustments to the carrying amounts and classification of assets, liabilities, and reported expenses that may be necessary if the Company were unable to continue as a going concern. If the Company is unable to raise additional capital and is therefore unable to continue as a going concern, it may seek protection under the bankruptcy laws and potentially have to liquidate its assets and may receive less than the value at which those assets are carried on its consolidated financial statements, and it is likely that investors will lose all or part of their investment.
Reverse Stock Split	Reverse Stock Split On April 26, 2022, the Company effected a reverse stock split of its common stock, par value $0.00001 per share, at a ratio of 1-for-25 (the “2022 Reverse Stock Split”). As a result of the 2022 Reverse Stock Split, (i) every 25 shares of the issued and outstanding common stock were automatically converted into one newly issued and outstanding share of common stock, without any change in the par value per share; (ii) the number of shares of common stock into which each outstanding warrant or option to purchase common stock is exercisable was proportionally decreased, and (iii) the number of authorized shares of common stock outstanding was proportionally decreased. Shares of common stock underlying outstanding stock options and other equity instruments convertible into common stock were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased in accordance with the terms of the agreements governing such securities. The 2022 Reverse Stock Split became effective at 5:00 pm New York time on April 26, 2022, with the common stock trading on a post-split basis under the Company's existing trading symbol, “NVIV,” at the market open on April 27, 2022. Fractional shares resulting from the 2022 Reverse Stock Split were rounded up to the nearest whole share, and all shares of common stock (including fractions thereof) issuable upon the 2022 Reverse Stock Split to a given stockholder were aggregated for the purpose of determining whether the 2022 Reverse Stock Split would result in the issuance of a fractional share. Pursuant to Section 78.209 of the Nevada Revised Statutes, the Company’s Board of Directors was able take action to effect the 2022 Reverse Stock Split by filing a Certificate of Change with the Secretary of State of the State of Nevada without the consent of the Company’s stockholders. All of the Company’s historical share and per share information related to issued and outstanding common stock and outstanding options and warrants exercisable for common stock in these consolidated financial statements have been adjusted, on a retroactive basis, to reflect the 2022 Reverse Stock Split.
