Some of the statements in this prospectus and the documents incorporated by reference herein constitute forward-looking statements that involve risks and uncertainties.

Business Overview

Overview

We are a research and clinical-stage biomaterials and biotechnology company with a focus on treatment of spinal cord injuries, or SCIs. Our approach to treating acute SCIs is based on our investigational Neuro-Spinal Scaffold™ implant, a bioresorbable polymer scaffold that is designed for implantation at the site of injury within a spinal cord and is intended to treat acute SCI. The Neuro-Spinal Scaffold implant incorporates intellectual property licensed under an exclusive, worldwide license from Boston Children’s Hospital, or BCH, and the Massachusetts Institute of Technology, or MIT. We also plan to evaluate other technologies and therapeutics that may be complementary to our development of the Neuro-Spinal Scaffold implant, such as stem cells, therapeutics or electrical stimulation, including in combination with learnings applied from our Neuro-Spinal Scaffold implant or technologies that offer the potential to bring us closer to our goal of redefining the life of the SCI patient.

Corporate Information

We were incorporated on April 2, 2003, under the name of Design Source, Inc. On October 26, 2010, we acquired the business of InVivo Therapeutics Corporation, which was founded in 2005, and we are continuing the existing business operations of InVivo Therapeutics Corporation as our wholly owned subsidiary.

Our principal executive offices are located in leased premises at One Kendall Square, Suite B14402, Cambridge, Massachusetts 02139. Our telephone number is (617) 863-5500. We maintain a website at www.invivotherapeutics.com. Information contained on, or accessible through, our website is not a part of, and is not incorporated by reference into, this prospectus.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company,” meaning that the market value of our stock held by non-affiliates is less than $700 million and our annual revenue was less than $100 million during our most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million. For so long as we remain a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure and other requirements that are applicable to other public companies that are not smaller reporting companies.

TABLE OF CONTENTS

PRIVATE PLACEMENT OF SHARES OF COMMON STOCK AND WARRANTS

On October 7, 2022, we entered into two securities purchase agreements with Armistice Capital Master Fund, Ltd., or Armistice, in connection with a concurrent registered direct offering and private placement, which we refer to as the offerings:

•

a securities purchase agreement pursuant to which we agreed to issue and sell to Armistice: (i) in a registered direct offering priced at-the-market under Nasdaq rules 154,000 shares of our common stock for a purchase price of $5.25 per share and associated preferred investment option, and pre-funded warrants to purchase up to 369,810 shares of our common stock, for a purchase price of $5.2499 per pre-funded warrant and associated preferred investment option, and (ii) in a concurrent private placement, preferred investment options to purchase up to 523,810 shares of our common stock.

•

a securities purchase agreement pursuant to which we agreed to issue and sell to Armistice, in a private placement priced at-the-market under Nasdaq rules, (i) pre-funded warrants to purchase up to 1,190,476 shares of our common stock, for a purchase price of $5.2499 per pre-funded warrant and associated preferred investment option, and (ii) preferred investment options to purchase up to 1,190,476 shares of our common stock.

We received aggregate gross proceeds from the offerings of approximately $9.0 million, before deducting placement agent fees and offering expenses, and excluding the exercise of any preferred investment options. The offerings closed on October 11, 2022.

In connection with the private placement of the pre-funded warrants and preferred investment options, we entered into a registration rights agreement with the selling stockholder, pursuant to which we agreed to register for resale the shares of our common stock issuable upon exercise of the unregistered pre-funded warrants and preferred investment options.

Concurrent with the offerings, we also entered into a warrant amendment agreement with Armistice. Under the warrant amendment agreement, we agreed to amend certain existing warrants to purchase up to 80,139 shares of common stock that were previously issued to Armistice in March 2020, April 2020 and October 2020, with exercise prices of $68.75, $40.50 and $20.00 per share, respectively, in consideration for the purchase of our securities in the offering. Under the warrant amendment agreement, we agreed to (i) lower the exercise price of such existing warrants to $5.05 per share and (ii) extend the original expiration date of such existing warrants to five and one-half years following the closing of the offerings.

On August 31, 2022, we entered in an engagement letter with H.C. Wainwright & Co., LLC, or Wainwright, providing for the payment of certain fees and expenses in connection with Wainwright serving as placement agent for the offerings. Pursuant to the engagement letter, in connection with the closing of the offerings we issued to certain Wainwright’s associated persons placement agent preferred investment options to purchase up to an aggregate of 111,429 shares of our common stock. The placement agent preferred investment options have an exercise price equal to $6.5625 per share.

For a detailed description of the transactions contemplated by the securities purchase agreements with Armistice and the engagement letter with Wainwright and the securities issued pursuant thereto, see the section captioned “Selling Stockholders” in this prospectus. We filed the registration statement on Form S-1, of which this prospectus forms a part, to fulfill our contractual obligations under the registration rights agreement entered into concurrently with the securities purchase agreement with Armistice to provide for the resale by the selling stockholders of the shares of common stock offered hereby.

USE OF PROCEEDS

We are filing the registration statement of which this prospectus forms a part to permit the holders of certain outstanding pre-funded warrants and preferred investment options to purchase shares, or the warrant shares, of our common stock described in the section titled “Selling Stockholders” to resell such shares of common stock issuable upon exercise of such pre-funded warrants and preferred investment options.

The selling stockholders will receive all of the net proceeds from sales of the warrants shares sold pursuant to this prospectus and we will not receive any proceeds from the resale of any warrants shares offered by this prospectus by the selling stockholders.

However, in the event of full exercise of the pre-funded warrants and preferred investment options by payment of cash, we will receive aggregate gross proceeds of approximately $9.4 million. Any proceeds from the exercise of the pre-funded warrants and preferred investment options will be used for working capital, business development activities, and general corporate purposes. We cannot predict when or if the pre-funded warrants and preferred investment options will be exercised, and it is possible that the pre-funded warrants and preferred investment options may expire and never be exercised.

We, and not the selling stockholders, will pay the costs, expenses and fees in connection with the registration and sale of the warrants shares covered by this prospectus, but the selling stockholders will pay all discounts, commissions or brokers’ fees or fees of similar securities industry professionals and transfer taxes, if any, attributable to sales of the warrants shares.

TABLE OF CONTENTS

DESCRIPTION OF OUR CAPITAL STOCK

General

The following description of our capital stock is intended as a summary only and therefore is not a complete description of our capital stock. This description is based upon, and is qualified by reference to, applicable provisions of the Nevada Revised Statutes (the “NRS”), our articles of incorporation, as amended, and our amended and restated bylaws and, which are filed as exhibits to the registration statement of which this prospectus forms a part.

As of November 4, 2022, 1,914,970 shares of the Company’s Common Stock, $0.00001 par value, were issued and outstanding.

Our authorized capital stock consists of 250,000,000 shares of common stock, par value $0.00001 per share, and 1,000,000 shares of preferred stock, par value $0.00001 per share. Our common stock is registered under Section 12(b) of the Exchange Act.

Common Stock

Voting Rights. The holders of our common stock are entitled to one vote per share on all matters submitted to a vote of the stockholders, including the election of directors. Generally, all matters to be voted on by stockholders must be approved by a majority (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all shares of common stock that are present in person or represented by proxy. Except as otherwise provided by law, amendments to our articles of incorporation generally must be approved by a majority of the votes entitled to be cast by all outstanding shares of common stock. Our articles of incorporation do not provide for cumulative voting in the election of directors.

Dividends. Except as provided by law or in our articles of incorporation, the holders of common stock will be entitled to such cash dividends as may be declared from time to time by our board of directors from funds available.

Liquidation, Dissolution and Winding Up. Upon liquidation, dissolution or winding up of our Company, the holders of common stock will be entitled to receive pro rata all assets available for distribution to such holders after payment of our liabilities.

Other Rights. The holders of common stock have no preferential or preemptive right and no subscription, redemption or conversion privileges with respect to the issuance of additional shares of our common stock.

Preferred Stock

Under the terms of our articles of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

Provisions of Our Articles of Incorporation and Bylaws and the NRS That May Have Anti-Takeover Effects

Anti-Takeover Effects of Provisions of Nevada State Law

We may be or in the future we may become subject to Nevada’s control share laws. A corporation is subject to Nevada’s control share law if it has more than 200 stockholders, at least 100 of whom are stockholders of record and residents of Nevada, and if the corporation does business in Nevada, including through an affiliated corporation. This control share law may have the effect of discouraging corporate takeovers. We currently have less than 100 stockholders of record who are residents of Nevada.

The control share law focuses on the acquisition of a “controlling interest,” which means the ownership of outstanding voting shares that would be sufficient, but for the operation of the control share law, to enable the acquiring person to exercise the following proportions of the voting power of the corporation in the election of directors: (1) one-fifth or more but less than one-third; (2) one-third or more but less than a

TABLE OF CONTENTS

majority; or (3) a majority or more. The ability to exercise this voting power may be direct or indirect, as well as individual or in association with others.

The effect of the control share law is that an acquiring person, and those acting in association with that person, will obtain only such voting rights in the control shares as are conferred by a resolution of the stockholders of the corporation, approved at a special or annual meeting of stockholders. The control share law contemplates that voting rights will be considered only once by the other stockholders. Thus, there is no authority to take away voting rights from the control shares of an acquiring person once those rights have been approved. If the stockholders do not grant voting rights to the control shares acquired by an acquiring person, those shares do not become permanent non-voting shares. The acquiring person is free to sell the shares to others. If the buyer or buyers of those shares themselves do not acquire a controlling interest, the shares are not governed by the control share law.

If control shares are accorded full voting rights and the acquiring person has acquired control shares with a majority or more of the voting power, a stockholder of record, other than the acquiring person, who did not vote in favor of approval of voting rights, is entitled to demand fair value for such stockholder’s shares.

In addition to the control share law, Nevada has a business combination law, which prohibits certain business combinations between Nevada corporations and “interested stockholders” for two years after the interested stockholder first becomes an interested stockholder, unless the corporation’s board of directors approves the combination in advance. For purposes of Nevada law, an interested stockholder is any person who is: (a) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the corporation, or (b) an affiliate or associate of the corporation and at any time within the previous two years was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then-outstanding shares of the corporation. The definition of “business combination” contained in the statute is sufficiently broad to cover virtually any kind of transaction that would allow a potential acquirer to use the corporation’s assets to finance the acquisition or otherwise to benefit its own interests rather than the interests of the corporation and its other stockholders.

The effect of Nevada’s business combination law is to potentially discourage parties interested in taking control of the Company from doing so if it cannot obtain the approval of our board of directors.

Anti-Takeover Effects of Provisions of Our Articles of Incorporation and Bylaws

Our articles of incorporation provide for a classified board of directors. This provision could prevent a party who acquires control of a majority of our outstanding common stock from obtaining control of the board until our second annual stockholders meeting following the date the acquirer obtains the controlling stock interest. The classified board provision could have the effect of discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us and could increase the likelihood that incumbent directors will retain their positions. In addition, under our amended and restated bylaws, directors may be removed only for cause and only by the affirmative vote of the holders of at least 80% of the voting power of our then outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class.

Our amended and restated bylaws also provide that stockholders may only act at meetings of stockholders and not by written consent in lieu of a stockholders’ meeting. Our amended and restated bylaws provide that stockholders may not call a special meeting of stockholders. Rather, only the Chairman of our board of directors, the President, or the board of directors pursuant to a resolution approved by a majority of the entire board of directors are able to call special meetings of stockholders. These provisions may discourage another person or entity from making a tender offer, even if it acquired a majority of our outstanding voting stock, because the person or entity could only take action at a duly called stockholders’ meeting relating to the business specified in the notice of meeting and not by written consent.

Our amended and restated bylaws also provide that stockholders may only conduct business at special meetings of stockholders that was specified in the notice of the meeting, and a stockholder must notify us in writing, within timeframes specified in our bylaws, of any stockholder nomination of a director and of any other business that the stockholders intends to bring at a meeting of stockholders. Our amended and restated bylaws also provide that our bylaws may be amended by our board of directors or by the affirmative

TABLE OF CONTENTS

vote of at least 80% of our voting stock then outstanding. These provisions could have the effect of discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us because the foregoing provisions may limit the proposals that may be acted upon at a stockholders’ meeting, and the amendment provisions in our bylaws make such provisions difficult to change.

Listing on The Nasdaq Capital Market

Our common stock is listed on the Nasdaq Capital Market under the symbol “NVIV.” On November 4, 2022, the reported closing price per share of our common stock on the Nasdaq Capital Market was $2.20.

Authorized but Unissued Shares

The authorized but unissued shares of common stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing requirements of the Nasdaq Capital Market. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock could make it more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Continental Stock Transfer & Trust Company.

SELLING STOCKHOLDERS

On October 7, 2022, we entered into certain securities purchase agreements, or the Purchase Agreements, with Armistice Capital Master Fund Ltd. or Armistice, pursuant to which we agreed to issue and sell to Armistice, in a private placement priced at-the-market under Nasdaq rules, (i) pre-funded warrants to purchase up to 1,190,476 shares of the Company’s common stock, for a purchase price of $5.2499 per unregistered pre-funded warrant and associated preferred investment option and (ii) preferred investment options to purchase up to 1,714,286 shares of our common stock and (iii) preferred investment options to purchase up to 523,810 shares of our common stock. In a concurrent registered offering, we also sold to Armistice 154,000 share of our common stock and pre-funded warrants to purchase up to 369,810 shares of our common stock.

In connection with the private placement of the pre-funded warrants and preferred investment options, we entered into a registration rights agreement with Armistice, pursuant to which we agreed to register for resale the shares of our common stock issuable upon exercise of the unregistered pre-funded warrants and preferred investment options. We agreed to file the registration statement with respect to the resale of such shares within 30 days after the date of the registration rights agreement. The registration rights agreement includes customary indemnification rights in connection with the registration statement. The registration statement of which this prospectus is a part has been filed in accordance with the registration rights agreement.

The common stock being offered by the selling stockholders are those issuable to the selling stockholders upon exercise of the pre-funded warrants and preferred investment options. We are registering the shares of common stock in order to permit the selling stockholders to offer the shares for resale from time to time. Except for the transactions described above, the selling stockholders have not had any material relationship with us within the past three years.

The table below lists the selling stockholders and other information regarding the beneficial ownership of the shares of common stock by the selling stockholders. The second column lists the number of shares of common stock beneficially owned by the selling stockholders, based on its ownership of the shares underlying the pre-funded warrants and preferred investment options, as of November 4, 2022, assuming exercise of the pre-funded warrants and preferred investment options held by the selling stockholders on that date, without regard to any limitations on exercises. The percentages of shares of common stock beneficially owned prior to and after the offering are based on 1,914,970 shares of common stock outstanding as of November 4, 2022, which includes the shares of common stock offered by this prospectus.

The third column lists the shares of common stock being offered by this prospectus by the selling stockholders.

In accordance with the terms of a registration rights agreement with the selling stockholders, this prospectus generally covers the resale of the sum of (i) the number of shares of common stock issued to the selling stockholders in the “Private Placement of Shares of Common Stock and Warrants” described

TABLE OF CONTENTS

above and (ii) the maximum number of shares of common stock issuable upon exercise of the related pre-funded warrants, determined as if the outstanding pre-funded warrants were exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination and all subject to adjustment as provided in the registration right agreement, without regard to any limitations on the exercise of the pre-funded warrants. The fourth column assumes the sale of all of the shares offered by the selling stockholders pursuant to this prospectus.

Under the terms of the pre-funded warrants, the selling stockholders may not exercise the pre-funded warrants to the extent such exercise would cause such selling stockholders, together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed 4.99% or 9.99%, as applicable, of our then outstanding common stock following such exercise, excluding for purposes of such determination shares of common stock issuable upon exercise of such pre-funded warrants which have not been exercised. The number of shares in the second and fourth columns do not reflect this limitation. The selling stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

We do not know when or in what amounts the selling stockholders may offer shares for sale. The selling stockholders might not sell any or all of the shares offered by this prospectus. Because the selling stockholders may offer all or some of the shares pursuant to this offering, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares, we cannot estimate the number of the shares that will be held by the selling stockholders after completion of the offering. However, for purposes of this table, we have assumed that, after completion of the offering, none of the shares covered by this prospectus will be held by the selling stockholders.

The shares of Common Stock include (i) 1,270,615 pre-funded warrants and (ii) 1,714,286 preferred investment options, all of which are directly held by Armistice Capital Master Fund Ltd. (the “Master Fund”), a Cayman Islands exempted company, and may be deemed to be indirectly beneficially owned by Armistice Capital, LLC (“Armistice”), as the investment manager of the Master Fund; and (ii) Steven Boyd, as the Managing Member of Armistice Capital. Armistice and Steven Boyd disclaim beneficial ownership of the reported securities except to the extent of their respective pecuniary interest therein. The pre-funded warrants are subject to a 9.99% beneficial ownership limitation and the preferred investment options are subject to a 4.99% beneficial ownership limitation, which prohibit the Master Fund from exercising any portion of them if, following such exercise, the Master Fund’s ownership of our Common Stock would exceed the applicable limitation. The amounts and percentages in the table do not give effect to those limitations. The address of the Master Fund is c/o Armistice Capital, LLC, 510 Madison Avenue, 7th Floor, New York, NY 10022.

(3)

The selling stockholder is an associated person of Wainwright, a registered broker-dealer and has sole voting and dispositive power over the securities held. The selling stockholder acquired the preferred investment options in the ordinary course of business and, at the time the preferred investment options were acquired, the selling stockholder had no agreement or understanding, directly or indirectly, with any person to distribute such securities.

PLAN OF DISTRIBUTION

Each selling stockholder, or the Selling Stockholders, of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•

an exchange distribution in accordance with the rules of the applicable exchange;

•

privately negotiated transactions;

•

settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

•

in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•

a combination of any such methods of sale; or

•

any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

TABLE OF CONTENTS

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information requirement under Rule 144 under the Securities Act or any other rule of similar effect or (ii) the date on which all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).
