(c) Except for the purchase by the Reporting Persons of T1 BSAs in connection with the Multi-Tranche Transaction (as defined and described in Item 6), the Reporting Persons have not entered into any transactions in the securities of the Issuer during the past sixty days.

Item 6.

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

Item 6 is hereby amended to add the following:

On October 11, 2024, the Issuer entered into subscription agreements (the "T1 Subscription Agreements") with certain investors (the "Investors"), including the Reporting Persons, pursuant to which the Issuer agreed to issue and sell to such Investors Shares, or in lieu thereof, pre-funded warrants to purchase Shares, as part of a multi-tranche private placement (the "Multi-Tranche Transaction").

The Multi-Tranche Transaction consists of the following:

·

The issuance of an aggregate of 34,600,507 Shares (the "T1 Shares") and 35,399,481 pre-funded warrants to purchase an aggregate of 35,399,481 Shares at an exercise price of €0.01 per new Share (the "T1 BSAs" and together with the T1 Shares, the "T1 Securities"), for aggregate gross proceeds of €94.1 million, subject to satisfaction of customary closing conditions. The subscription price for the T1 Shares is €1.35 per Share (the "T1 Share Subscription Price"), and the subscription price of each T1 BSA is €1.34 per Share (the "T1 BSA Subscription Price"), representing the T1 Share Subscription Price less the nominal value per Share of €0.01.

This initial tranche of the Multi-Tranche Transaction closed on October 17, 2024. In connection with the closing of this initial tranche, BVF, BVF2, Trading Fund OS and Partners (on behalf of the Partners Managed Account) purchased 3,974,936 T1 BSAs, 3,640,567 T1 BSAs, 470,954 T1 BSAs and 144,577 T1 BSAs, respectively.

The T1 BSAs provide that a holder of T1 BSAs shall not have the right to exercise any portion of its T1 BSAs if, after giving effect to such issuance after exercise, such holder, together with its Attribution Parties (as defined in the T1 Subscription Agreement), would beneficially own (as calculated in accordance with Section 13(d) of the Exchange Act or with respect to the French FDI Regime (as defined in the T1 Subscription Agreement)) in excess of 4.99% of the number of Shares outstanding immediately after giving effect to such exercise (the "T1 BSA Beneficial Ownership Limitation"); provided, however, that each holder may increase or decrease the T1 BSA Beneficial Ownership Limitation provided that (a) to the extent required by the French FDI Regime, in the cases of T1 BSA Beneficial Ownership Limitation increased above 9.99% of the voting rights of the Issuer (the "Crossing Event"), the holder has obtained from the French Ministry of Economy through an authorization request or prior notification, in accordance with the French FDI Regime, either (i) a written response from the French Ministry of Economy confirming that the exercise of the T1 BSAs and, therefore, the acquisition of underlying Shares that would cause the Crossing Event is not subject to the prior authorization procedure or (ii) the authorization (express or tacit) to proceed with the Crossing Event, and (b) the T1 BSA Beneficial Ownership Limitation in no event exceeds 19.99% of the number of Shares outstanding immediately after giving effect to the issuance of Shares upon exercise of the T1 BSAs held by the holder and the provisions of the T1 BSA Beneficial Ownership Limitation shall continue to apply (provided that, with respect to the French FDI Regime, the applicable percentage will be 24.99% of the voting rights of the Issuer).

·

The issuance of an aggregate of 7,872,064 Shares (the "T1bis Shares") and 8,053,847 pre-funded warrants to purchase an aggregate of 8,053,847 Shares at an exercise price of €0.01 per new Share (the "T1bis BSAs" and together with the T1bis Shares, the "T1bis Securities") for aggregate gross proceeds of €21.4 million, subject to satisfaction of applicable conditions precedent, including the approval of the shareholders at a general meeting of the shareholders to be held no later than December 16, 2024 (the "General Meeting"). The subscription price for the T1bis Shares and T1bis BSAs will be equal to the T1 Share Subscription Price and T1 BSA Subscription Price, respectively. The number of T1bis Securities will be subscribed by each Investor, including the Reporting Persons, pro rata to the number of T1 Securities subscribed for by the Investor.

·

The issuance of a number of Shares (or, in lieu of Shares, pre-funded warrants) (the "T2 Shares") to be determined by the Board, to which warrants to purchase Shares are attached (the "T3 BSAs" and together with the T2 Shares, the "ABSAs"), for aggregate gross proceeds of €116 million, subject to satisfaction of applicable conditions precedent, including the approval of the shareholders at the General Meeting. Pursuant to the T1 Subscription Agreement, upon the satisfaction of applicable conditions precedent, each Investor, including the Reporting Persons, will be obligated to purchase a number of ABSAs pro rata to the number of T1 Securities purchased by the Investor pursuant to a second subscription agreement (the "T2 Subscription Agreement" and together with the T1 Subscription Agreement, the "Subscription Agreements"). The subscription price of the ABSAs will be equal to the lower of (i) the T1 Share Subscription Price or (ii) the volume-weighted average of the price of the Shares on Euronext Paris during the five trading sessions preceding pricing of the ABSAs. The T3 BSAs will have an exercise price of €1.50 per Share and will only become exercisable upon the occurrence of a specified triggering event (or the waiver thereof), for maximum proceeds upon exercise of €116 million (assuming all T3 BSAs are exercised).

Pursuant to the T1 Subscription Agreement, the Issuer undertook to submit to the General Meeting the appointment of specified individuals as members of the Board. The Issuer further undertook to submit to the General Meeting or at a later general meeting of shareholders, up to four additional new members of the Board, in order to replace existing members of the Board (other than certain specified members), one of which upon proposal of the Reporting Persons, and three of which upon proposal of each of the three largest subscribers in the offering of T1 Securities.

The Investors, including the Reporting Persons, have undertaken to vote in favor of the resolutions of the General Meeting relating to the issuance of the T1bis Securities and the ABSAs (with the exception of the resolution relating to the Investor's own investment) and relating to changes in the governance of the Issuer.

The Investors, including the Reporting Persons, have agreed to a lock-up on the T1 Shares, the T1 BSAs and the Shares issued upon the exercise of the T1 BSAs until the earlier of (x) the issuance date of the ABSAs or (y) May 20, 2025, subject to certain exceptions (including transfers to an affiliate to the Investor, to another Investor, or, subject to the agreement of the Issuer in its sole discretion, to any third party who makes the same lock-up commitment on such securities). The T1bis Shares will be held by Investors, including the Reporting Persons, under the same conditions as the T1 Shares in the event of their issuance.

The foregoing description of the Multi-Tranche Transaction and the Subscription Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the Subscription Agreements, which are referenced hereto as Exhibits 99.1 and 99.2 and are incorporated by reference herein.

Item 7.
