The Company also respectfully advises the Staff that the Company updated the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Salarius” beginning on page 136 of Amendment No. 1 to reflect the Company’s financial results for the fiscal year ended December 31, 2024.

Unaudited Pro Forma Consolidated Combined Financial Information, page 190

10.Please explain why the Company is using the words assumed and agreed to fair value for Salarius Pharmaceuticals, Inc. when it is a public company with a published market value. If the assumed and/or agreed to value is in fact market value, please revise your filing accordingly. Additionally, explain how you determined the fair value for Decoy Therapeutics Inc. as we noted you used the same language, assumed and agreed to fair value.

Response:

The Company respectfully advises the Staff that the Company referred to the Company’s “assumed value” on page 190 of the Form S-1 because the original Merger Agreement contemplated that the Company’s and Decoy’s respective base values would be subject to adjustment based on the balance sheet cash available to each of the Company and Decoy at closing of the Merger. On March 28, 2025, the Company and Decoy entered into Amendment No.1 to the Merger Agreement (the “Merger Agreement Amendment”), pursuant to which the parties agreed to eliminate this adjustment mechanism. Accordingly, the relative ownership percentages of the combined company is effectively fixed, with Company legacy stockholders retaining 14.1% and Decoy’s legacy stockholders retaining 85.9% of the combined company following the completion of the Merger, in each case calculated on a fully-diluted basis, and before taking into account the dilutive effects of this offering and any issuance of shares pursuant to financings after January 10, 2025, the date of entry into the original Merger Agreement. The Company has updated the Unaudited Pro Forma information beginning on page 191 of Amendment 1 to reflect the effect of the Merger Agreement Amendment.

In respect to the Staff’s comment, the Company respectfully advises the Staff that the terms of the Merger Agreement are the result of arm’s-length negotiations between the management team of the Company and the management team of Decoy, along with their respective advisors, and under the direction of each company’s board of directors. The parties agreed to a value of $4.6 million for Salarius (assuming Salarius delivers $0 of net cash at closing) based on a $3.1 million proposed valuation of the Company’s public company listing (based on the Company's then-current market capitalization, which was approximately $2.1 million as of October 11, 2024, the date the term sheet between the Company and Decoy was entered

into) and $1.5 million for certain of the Company’s clinical assets. The Company has revised the disclosure on pages 191 and 196 of Amendment No. 1 to clarify the basis upon which the parties agreed to a $4.6 million valuation for Salarius.

With respect to Decoy’s valuation, the Company also respectfully advises the Staff that the parties agreed to a value of $28.0 million for Decoy. The parties agreed to the valuation based on, among other things, an implied valuation of Decoy in connection with the issuance of previously issued convertible notes issued by Decoy in 2022 (which had assigned the Company an implied value of $25 million), Decoy’s ongoing scientific and technical achievements over the ensuing years following the issuance of such convertible notes, and publicly available information regarding the value of certain of Decoy’s competitors.

11.We note language that the pro forma adjustments are preliminary and are not finalized. As these amounts are preliminary, we will further examine the Unaudited Pro Forma information and adjustments in a subsequent submission. In a subsequent amendment, please ensure that the narrative information within the Notes to the Unaudited Pro Forma Consolidated Combined Financial Information is consistent between the notes, and can be clearly calculated to equal the quantitative values on the Unaudited Pro Forma Consolidated Combined Balance Sheet and Statement of Operations.

Response: In response to the Staff’s comment, the Company respectfully advises the Staff that the Company has added updated Unaudited Pro Forma information beginning on page 191 of Amendment No. 1.

Salarius respectfully requests the Staff’s assistance in completing the review of the Registration Statement as soon as possible. Please advise us if we can provide any further information or assistance to facilitate your review. If the Staff should have any questions, or would like further information, concerning any of the responses above, please do not hesitate to contact the undersigned at (267) 675-4642. We thank you in advance for your attention to the above.

Sincerely,
/s/ Stephen M. Nicolai
