Item 4.Purpose of Transaction

The Filers are filing this Schedule 13D because one of EcoR1’s employees, Scott Platshon, was appointed to the Issuer’s board of directors on February 22, 2024. The Filers acquired the Stock for investment purposes based on their belief that the Stock, when purchased, was undervalued and represented an attractive investment opportunity.  The Filers will routinely monitor the Issuer regarding a wide variety of factors that affect their investment considerations, including, current and anticipated future trading prices of the Stock and other securities, the Issuer’s operations, assets, prospects, financial position, and business development, Issuer’s management, Issuer-related competitive and strategic matters, general economic, financial market and industry conditions, and other investment considerations. Depending on their evaluation of various factors, the Filers may take such actions regarding their holdings of the Issuer’s securities as they deem appropriate in light of circumstances existing from time to time. Such actions may include purchasing additional Stock in the open market, through privately negotiated transactions with third parties or otherwise, and selling at any time, in the open market, through privately negotiated transactions with third parties or otherwise, all or part of the Stock that they now own or hereafter acquire. The Filers also may from time to time enter into or unwind hedging or other derivative transactions with respect to the Stock or pledge their interests in the Stock to obtain liquidity. In addition, from time to time the Filers and their representatives and advisers may communicate with other stockholders, industry participants and other interested parties about the Issuer.

The Filers have no present plan or proposal that relates to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. However, the Filers may recommend action to the Issuer’s management, board of directors and stockholders. Any such actions could involve one or more of the events referred to in clauses (a) through (j) of Item 4 of Schedule 13D, including, potentially, one or more mergers, consolidations, sales or acquisitions of assets, changes in control, issuances, purchases, dispositions or pledges of securities or other changes in capitalization.

Item 5.Interest in Securities of the Issuer

The percentages reported in this Schedule 13D are based on 70,001,987 shares of the Issuer’s Common Stock outstanding as of November 6, 2023, as reported in the Issuer’s Form 10-Q filed on November 7, 2023.

(a) and (b) The aggregate number and percentage of shares of the Issuer’s Common Stock beneficially owned by each Filer on the date hereof is reflected on that Filer’s cover page.

The shares of the Issuer’s Common Stock beneficially owned by EcoR1 and Mr. Nodelman consist of 13,437,473 shares of Common Stock held by the private investment funds managed by EcoR1 and 5,086,521 shares of Common Stock issuable to those funds pursuant to Pre-Funded Warrants issued by the Issuer, which warrants are subject to a 19.99% beneficial ownership limitation.

The shares of the Issuer’s Common Stock beneficially owned by Qualified Fund consists of 12,658,224 shares of Common Stock and 4,818,462 shares of Common Stock issuable to Qualified Fund pursuant to Pre-Funded Warrants issued by the Issuer, which warrants are subject to a 19.99% beneficial ownership limitation.

(d)       Not applicable.

(e)       Not applicable.

Item 6.Contracts, Arrangement, Understandings or Relationships with Respect to Securities of the Issuer

 

EcoR1 is the investment adviser to its clients pursuant to investment management agreements or limited partnership agreements providing to EcoR1 the authority, among other things, to invest the funds of such clients in Stock, to vote and dispose of Stock and to file this statement on behalf of such clients. Pursuant to such limited partnership agreements, EcoR1 is entitled to allocations based on assets under management and realized and unrealized gains. Pursuant to such investment management agreements, EcoR1 is entitled to fees based on assets under management and realized and unrealized gains.

Securities Purchase Agreement

On December 23, 2023, the Filers entered into a securities purchase agreement (the “Securities Purchase Agreement”) for a private placement with the Issuer. Pursuant to the Securities Purchase Agreement, the Filers purchased 5,086,521 pre-funded warrants (the “Pre-Funded Warrants”) to purchase 5,086,521 shares of Common Stock of the Issuer (the “Warrant Shares”). In addition, the Issuer agreed that EcoR1 will have the right to nominate one of its partners as a member of the board of directors of the Issuer, subject to specified conditions. Such nomination right will terminate upon the earliest of the effective date of such appointment and January 1, 2026.

Pre-Funded Warrants

The Pre-Funded Warrants will be exercisable at an exercise price equal to $0.0001 per share, subject to adjustments as provided under the terms of the Pre-Funded Warrants. The Pre-Funded Warrants are exercisable at any time, except that the Pre-Funded Warrants cannot be exercised if, after giving effect or immediately prior to such exercise, the Filers, together with their affiliates and any other persons whose beneficial ownership of shares of Common Stock would be aggregated with the Filers for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), would beneficially own more than 19.99% (the “Maximum Percentage”) of the total number of issued and outstanding shares of Common Stock or voting power of the Issuer following such exercise. The Maximum Percentage may be increased or decreased by the Filers with 61 days’ written notice to the Issuer; provided, however, that such percentage may in no event exceed 19.99%.

Registration Rights Agreement

The Filers also entered into a registration rights agreement (the “Registration Rights Agreement”) with the Issuer on December 23, 2023, requiring the Issuer to register the resale of the Warrant Shares (the “Registrable Securities”). Under the Registration Rights Agreement, the Issuer agreed to file a registration statement covering the resale by the Filers of their Registrable Securities upon the earlier of March 15, 2024 and the first business day following the date that the Issuer files it Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “Filing Deadline”).

The Issuer agreed to use commercially reasonable efforts to cause such registration statement or final prospectus, as applicable, to be declared effective as soon as practicable, but no later than the later of April 29, 2024 and the 123rd calendar day following the closing date (the “Effectiveness Deadline”), and to keep such registration statement effective for a period that will terminate upon the earliest of (i) the date that all Registrable Securities covered by such registration statement or final prospectus, as applicable, have been sold, (ii) the date that all Registrable Securities covered by such registration statement or final prospectus, as applicable, may be sold without the requirement for the Issuer to be in compliance with the current public information required under Rule 144 as to such Registrable Securities and without volume or manner-of-sale restrictions and (iii) two (2) years after the date of the Securities Purchase Agreement. The Issuer agreed to be responsible for all reasonable expenses in connection with the filing of any registration statement or final prospectus, as applicable. For the avoidance of doubt, the fees and expenses of the Filers’ counsel shall be the responsibility of the Filers, and not the Issuer.

In the event (i) the registration statement or final prospectus, as applicable, covering the Registrable Securities has not been filed with the Securities and Exchange Commission (the “SEC”) on or prior to the Filing Deadline, (ii) the registration statement or final prospectus, as applicable, covering the Registrable Securities is not declared effective by the SEC prior to the earlier of (a) ten (10) business days after the date on which the Issuer is notified by the SEC that the registration statement or final prospectus, as applicable, will not be reviewed by the SEC or is not subject to further comment by the SEC and (b) the Effectiveness Deadline, or (iii) after the registration statement or final prospectus, as applicable, has been declared effective by the SEC, sales cannot be made pursuant to the registration statement or final prospectus, as applicable, for any reason, subject to certain limited exceptions, then the Issuer has agreed to make pro rata payments to each Filer as liquidated damages and not as a penalty, in an amount equal to one percent (1%) of the aggregate purchase price paid by such Issuer pursuant to the Securities Purchase Agreement for any shares of Common Stock held by such Issuer pursuant to the exercise of Pre-Funded Warrants but not for any unissued shares of Common Stock issuable upon exercise of the Pre-Funded Warrants for each 30-day period or pro rata for any portion thereof (a) following the Filing Deadline for which no registration statement or final prospectus, as applicable, is filed with respect to the Registrable Securities or (b) during which such registration statement or final prospectus, as applicable, is unavailable, as applicable. Payment of such liquidated damages shall be the Filers’ exclusive remedy for such events. In addition, (i) the aggregate amount of liquidated damages payable to a Filer shall not exceed, in the aggregate, six percent (6%) of the aggregate purchase price paid by such Filer and (ii) the Issuer shall not be liable in any thirty (30) day period for liquidated damages in excess of one percent (1%) of the aggregate purchase price paid by the Filer.

The Issuer has granted the Filers customary indemnification rights in connection with the registration statement. The Filers have also granted the Issuer customary indemnification rights in connection with the registration statement.

The foregoing description of the material terms of the Securities Purchase Agreement, the Registration Rights Agreement and the Form of Pre-Funded Warrant to purchase shares of Common Stock is qualified in its entirety by reference to those documents, each of which is referenced in Exhibits B, C and D hereto, respectively, and is incorporated by reference herein.
