**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Common Stock, $0.001 par value

**(b) Name of Issuer:**
Dianthus Therapeutics, Inc.

**(c) Address of Issuer's Principal Executive Offices:**
7 TIMES SQUARE, 43RD FLOOR, NEW YORK, NY, 10036

Common stock, $0.001 par value of Dianthus Therapeutics, Inc. (the "Issuer" or the "Company")

**Item 4. Purpose of Transaction**

The Reporting Persons are filing this Amendment No. 3 to report a greater than 1.00% decrease in the percentage of shares of Common Stock beneficially owned by the Reporting Persons due to the sale of shares of Common Stock by private investment funds managed by Avidity Partners Management LP, including Avidity Private Master Fund I LP.

Although the Reporting Persons do not have any specific plan or proposal to acquire, transfer or dispose of Common Stock at the time of this filing, consistent with their investment purpose, the Reporting Persons may, either directly or through one or more affiliates, from time to time or at any time and subject to price, market and general economic and fiscal conditions and other factors, acquire or seek to acquire additional shares of Common Stock in the open market, in privately negotiated transactions or otherwise, or dispose of or seek to dispose of all or a portion of such shares of Common Stock now owned or hereafter acquired. The Reporting Persons reserve the right to change their intention with respect to any or all of the matters required to be disclosed in this Item 4.

The Reporting Persons have not made a determination regarding a maximum or minimum number of shares of Common Stock or other securities of the Issuer that it may hold at any point in time.

Except as set forth herein and below, or as would occur upon completion of any of the matters discussed herein, the Reporting Persons have no present plans or proposals that would relate to or result in any of the matters set forth in clauses (a) through (j) of Item 4 of Schedule 13D. Although the foregoing reflects activities presently contemplated by such persons with respect to the Issuer, the foregoing is subject to change at any time.

**Item 5. Interest in Securities of the Issuer**

**(a)**
The information set forth in Items 2, 3 and 4 is hereby incorporated by reference into this Item 5.
The aggregate number of shares of Common Stock and the percentage of total outstanding shares of Common Stock beneficially owned by the Reporting Persons is set forth below. References to percentage ownerships of shares of Common Stock in this statement are based on 42,876,015 shares of Common Stock outstanding as of November 3, 2025 as reported in the Issuer's Form 10-Q filed with the Securities and Exchange Commission on November 5, 2025. The filing of this statement shall not be construed as an admission that a Reporting Person beneficially owns those shares held by any other Reporting Person.

**(b)**
Avidity Partners Management LP, Avidity Partners Management (GP) LLC, Avidity Capital Partners Fund (GP) LP, Avidity Capital Partners (GP) LLC and Michael Gregory have shared power to vote or to direct the vote and shared power to dispose or to direct the disposition of 2,104,184 shares of the Common Stock reported in (a) above.

**(c)**
Avidity Private Master Fund I LP has shared power to vote or to direct the vote and shared power to dispose or to direct the disposition of 1,899,593 shares of the Common Stock reported in (a) above.

The transactions in the Common Stock by the Reporting Persons during the past sixty days in respect of the Issuer are set forth on Exhibit B.

All of the securities in this Schedule 13D are owned by advisory clients of Avidity Partners Management LP. Other than Avidity Private Master Fund I LP, no such client(s) 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 Common Stock in an amount equal to more than five percent of the class.

The Reporting Persons no longer beneficially own 5% or more of the total outstanding shares of Common Stock.  Consequently, this Amendment No. 3 is the final amendment to the Schedule 13D and constitutes an "exit filing" for the Reporting Persons.

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

The information set forth in Items 2, 3, 4 and 5 is hereby incorporated by reference into this Item 6.  The Reporting Persons do not have any contract, arrangement, understanding or relationship with any person with respect to securities of the Issuer that is not described herein and/or in a previous Schedule 13D filed by the Reporting Persons in respect of the Issuer.
