Item 1.Security and Issuer

 

Item 1 of the Statement is hereby amended and supplemented as follows:

 

This Amendment No. 1 (this “Amendment No. 1” or this “13D/A”) amends and supplements the statement on Schedule 13D originally filed with the Securities and Exchange Commission (the “SEC”) on September 27, 2021 (the “Statement”) by RA Capital Management, L.P. (“RA Capital”), Peter Kolchinsky, Rajeev Shah and RA Capital Healthcare Fund, L.P. (the “Fund”) with respect to the common stock, $0.001 par value per share (“Common Stock”), of Janux Therapeutics, Inc., a Delaware corporation (the “Issuer”). Unless otherwise defined herein, capitalized terms used in this Amendment No. 1 shall have the meanings ascribed to them in the Statement.

 

Item 2.Identity and Background

 

Item 2(a) of the Statement is hereby amended and restated as follows:

 

(a)This Amendment No. 1 is being filed on behalf of RA Capital Management, L.P. (“RA Capital”), Peter Kolchinsky, Rajeev Shah, and RA Capital Healthcare Fund, L.P. (the “Fund”) and are collectively referred to herein as the “Reporting Persons.” The agreement among the Reporting Persons to file this Schedule 13D jointly in accordance with Rule 13d-1(k) of the Securities Exchange Act of 1934, as amended, is attached hereto as Exhibit 1.

 

The Fund directly holds (i) 8,117,246 shares of Common Stock; (ii) pre-funded warrants (the “2023 Pre-Funded Warrants”) exercisable for up to 503,226 shares of Common Stock; and (iii) pre-funded warrants (the “2024 Pre-Funded Warrants” and, together with the 2023 Pre-Funded Warrants, the “Pre-Funded Warrants”) exercisable for up to 1,397,849 shares of Common Stock. RA Capital Nexus Fund II, L.P. (the “Nexus Fund II”) directly holds 1,048,406 shares of Common Stock. Each of the 2023 Pre-Funded Warrants and the 2024 Pre-Funded Warrants contains a provision (the “Beneficial Ownership Blockers”) which precludes exercise of the warrants to the extent that, following exercise, the Fund, together with its affiliates and other attribution parties, would own more than 19.90% and 19.99%, respectively, of the Common Stock outstanding.

 

The Common Stock reported herein as beneficially owned by the Reporting Persons consists of (i) 8,117,246 shares of Common Stock held directly by the Fund; (ii) 1,048,406 shares of Common Stock held directly by the Nexus Fund II; (iii) an aggregate of 1,376,493 shares of Common Stock that the Reporting Persons have the right to acquire upon the exercise of Pre-Funded Warrants, as limited by the Beneficial Ownership Blockers; and (iv) a total of 47,500 shares underlying vested stock options (right to buy), and 3,750 shares underlying stock options (right to buy) which shall vest within 60 days of this filing held by Jake Simson for the benefit of RA Capital. The Fund is currently prohibited from exercising the Pre-Funded Warrants to the extent that such exercise would result in the Reporting Persons’ beneficial ownership of more than 10,593,395 shares of Common Stock.

 

RA Capital Healthcare Fund GP, LLC is the general partner of the Fund and RA Capital Nexus Fund II GP, LLC is the general partner of the Nexus Fund II. The general partner of RA Capital is RA Capital Management GP, LLC, of which Dr. Kolchinsky and Mr. Shah are the controlling persons. RA Capital serves as investment adviser for the Fund and the Nexus Fund II and may be deemed a beneficial owner, for purposes of Section 13(d) of the Securities Exchange Act of 1934 (the “Act”), of any securities of the Issuer held by the Fund or the Nexus Fund II. The Fund and the Nexus Fund II have delegated to RA Capital the sole power to vote and the sole power to dispose of all securities held in the Fund’s and the Nexus Fund II’s portfolio, including the shares of the Issuer’s Common Stock reported herein. Because the Fund and the Nexus Fund II have divested themselves of voting and investment power over the reported securities they hold and may not revoke that delegation on less than 61 days’ notice, the Fund and the Nexus Fund II disclaim beneficial ownership of the securities they hold for purposes of Section 13(d) of the Act and therefore disclaim any obligation to report ownership of the reported securities under Section 13(d) of the Act. As managers of RA Capital, Dr. Kolchinsky and Mr. Shah may be deemed beneficial owners, for purposes of Section 13(d) of the Act, of any securities of the Issuer beneficially owned by RA Capital. RA Capital, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of the securities reported in this 13D/A other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of the 13D/A shall not be deemed an admission that either RA Capital, Dr. Kolchinsky, or Mr. Shah is the beneficial owner of such securities for any other purpose.

 

(b)The address of the principal business office of each of the Reporting Persons is 200 Berkeley Street, 18th Floor, Boston, MA 02116.

 

 

 

 

(c)The Fund is a private investment vehicle. RA Capital provides investment management services to the Fund and the Nexus Fund II. The principal occupation of each of Dr. Kolchinsky and Mr. Shah is investment management.

 

(d)During the last five years, none of the Reporting Persons, nor to the Reporting Persons’ knowledge, any of the persons listed in Schedule A, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

 

(e)During the last five years, none of the Reporting Persons, nor to the Reporting Persons’ knowledge, any of the persons listed in Schedule A, has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree of final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

 

(f)See Item 6 of the cover pages.

 

Item 3.Source and Amount of Funds or Other Consideration

 

Item 3 of the Statement is hereby amended and supplemented to add the following:

0;

On March 4, 2024, the Fund purchased 1,397,849 2024 Pre-Funded Warrants in the Issuer’s underwritten public offering (the “March 2024 Public Offering”) at a price of $46.499 per 2024 Pre-Funded Warrant, for total consideration of $65 million. The purchase was for cash and was funded by the working capital of the Fund.

 

Item 5.Interest in Securities of the Issuer

 

Item 5 of the Statement is hereby amended and restated in its entirety to read as follows:

 

(a)The information set forth in rows 11 and 13 of the cover pages to this 13D/A is incorporated by reference. The percentage set forth in row 13 is based on the sum of (i) 51,565,731 outstanding shares of Common Stock as of March 4, 2024, as reported by the Issuer in its prospectus supplement dated February 28, 2024, filed with the Securities and Exchange Commission on February 29, 2024, (ii) an aggregate of 1,376,493 shares of Common Stock which the Reporting Person may acquire upon the exercise of Pre-Funded Warrants, as limited by the Beneficial Ownership Blockers and (iii) an aggregate of 51,250 shares issuable upon exercise of options held by Mr. Simson within 60 days.

 

(b)The information set forth in rows 7 through 10 of the cover pages to this 13D/A and Item 2 above is incorporated by reference.

 

(c)Schedule A sets forth all transactions with respect to the shares of Common Stock effected during the past sixty days by any Reporting Person and is incorporated herein by reference.

 

(d)No person (other than the Reporting Persons) is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock subject to this 13D/A.

 

(f)Not applicable.

 

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

 

Item 6 of the Statement is hereby amended and supplemented to add the following:

 

Item 3 is incorporated by reference.

 

2023 Pre-Funded Warrants

 

Each 2023 Pre-Funded Warrant has an exercise price of $0.001 per share of Common Stock, is immediately exercisable and does not expire. Under the terms of the 2023 Pre-Funded Warrants, the Issuer may not effect the exercise of any 2023 Pre-Funded Warrant, and the Fund will not be entitled to exercise any portion of any 2023 Pre-Funded Warrant, which, upon giving effect to such exercise, would cause the Fund (together with its affiliates) to own more than 19.9% of the number of shares of the Common Stock outstanding immediately after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the 2023 Pre-Funded Warrants.

 

 

 

 

The exercise price and the number of shares of Common Stock issuable upon exercise of each 2023 Pre-Funded Warrant are subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Common Stock.

 

In the event of certain fundamental transactions (as described in the 2023 Pre-Funded Warrants), a holder of 2023 Pre-Funded Warrants will be entitled to receive, upon exercise of the 2023 Pre-Funded Warrants, the kind and amount of securities, cash or property that such holder would have received had they exercised in full the 2023 Pre-Funded Warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the 2023 Pre-Funded Warrants.

 

References to and the description of the 2023 Pre-Funded Warrants set forth above in this Item 6 do not purport to be complete and are qualified in their entirety by reference to the full text of the Form of 2023 Pre-Funded Warrant, which is attached hereto as Exhibit 4 and incorporated by reference herein.

In connection with the March 2024 Public Offering that closed on March 4, 2024, BofA Securities, Inc., Cowen and Company, LLC, Cantor Fitzgerald & Co. and William Blair & Company, L.L.C as representatives of the several underwriters (collectively the “Representatives”) entered into a lockup agreement (the “2024 Lockup Agreement”) with each of the Issuer’s directors, including Mr. Simson. Pursuant to the 2024 Lockup Agreement, subject to certain exceptions, Mr. Simson agreed not to offer, sell or transfer any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock, or enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, without the prior written consent of BofA Securities, Inc. and Cowen and Company, LLC for a period of 90 days from February 28, 2024. A copy of the form of Lock-Up Agreement is filed as Exhibit 5 to this filing and is incorporated by reference herein.

 

2024 Pre-Funded Warrants

 

Each 2024 Pre-Funded Warrant has an exercise price of $0.001 per share of Common Stock, is immediately exercisable and does not expire. Under the terms of the 2024 Pre-Funded Warrants, the Issuer may not effect the exercise of any 2024 Pre-Funded Warrant, and the Fund will not be entitled to exercise any portion of any 2024 Pre-Funded Warrant, which, upon giving effect to such exercise, would cause the Fund (together with its affiliates) to own more than 19.99% of the number of shares of the Common Stock outstanding immediately after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the 2024 Pre-Funded Warrants. However, the Fund may increase or decrease such percentage, from time to time, to any other percentage not in excess of 19.99%, provided that any increase in such percentage shall not be effective until 61 days after such notice is delivered to the Issuer.

 

The exercise price and the number of shares of Common Stock issuable upon exercise of each 2024 Pre-Funded Warrant are subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Common Stock.

 

In the event of certain fundamental transactions (as described in the 2024 Pre-Funded Warrants), a holder of 2024 Pre-Funded Warrants will be entitled to receive, upon exercise of the 2024 Pre-Funded Warrants, the kind and amount of securities, cash or property that such holder would have received had they exercised in full the 2024 Pre-Funded Warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the 2024 Pre-Funded Warrants.

 

References to and the description of the 2024 Pre-Funded Warrants set forth above in this Item 6 do not purport to be complete and are qualified in their entirety by reference to the full text of the Form of 2024 Pre-Funded Warrant, which is attached hereto as Exhibit 6 and incorporated by reference herein.
