(the "Company") filed a prospectus supplement (the "Prospectus Supplement") under the Company's universal shelf registration statement on Form S-3 (File No. 333-276950) that was originally filed with the Securities and Exchange Commission (the "SEC") on February 8, 2024 and was declared effective by the SEC on April 12, 2024 (the "Registration Statement"), relating to the offer and sale of a total of up to $8,137,047 of shares of the Company's common stock, par value $0.01 per share (the "Shares"), pursuant to an Amended and Restated Sales Agreement, dated February 8, 2024, between the Company and Cantor Fitzgerald & Co. ("Cantor") and JonesTrading Institutional Services LLC ("Jones"), as agents (the "Sales Agreement").

As previously disclosed, on July 1, 2025, the Company notified Cantor and Jones that it was terminating a prior prospectus filed with the SEC on February 8, 2024 and dated April 12, 2024 related to the offer and sale of shares of the Company's common stock having an aggregate offering price of up to $100.0 million pursuant to the Sales Agreement. The Sales Agreement remained in full force and effect.

Wilmer Cutler Pickering Hale and Dorr LLP, counsel to the Company, has issued a legal opinion relating to the Shares. A copy of such legal opinion, including the consent included therein, is attached as Exhibit 5.1 hereto.

The Shares are registered pursuant to the Registration Statement and the base prospectus contained therein, and offerings for the Shares will be made only by means of the Prospectus Supplement. This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction.

Re:&nbsp;&nbsp;&nbsp;&nbsp;<u>Prospectus Supplement to Registration Statement on Form S-3</u>

Ladies and Gentlemen:

This opinion is furnished to you in connection with (i) the Registration Statement on Form S-3 (File No. 333- 276950) (the "Registration Statement") filed by Curis, Inc., a Delaware corporation (the "Company"), with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), for the registration of common stock, $0.01 par value per share (the "Common Stock"), which may be issued from time to time on a delayed or continuous basis pursuant to Rule 415 under the Securities Act with an aggregate offering price of up to $300,000,000, as set forth in the Registration Statement and the prospectus contained therein (the "Base Prospectus") and (ii) the prospectus supplement, dated August 8, 2025 (the "Prospectus Supplement" and, together with the Base Prospectus, the "Prospectus") relating to the issuance and sale from time to time by the Company of shares of Common Stock with an aggregate offering price of up to $8,137,047 (the "Shares").

The Shares are to be issued and sold by the Company pursuant to an Amended and Restated Sales Agreement, dated February 8, 2024, between the Company and Cantor Fitzgerald & Co. and JonesTrading Institutional Services LLC, as agents (the "Sales Agreement"), which is filed as Exhibit 10.48 to the Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

We are acting as counsel for the Company in connection with the issue and sale by the Company of the Shares pursuant to the Sales Agreement. We have examined and relied upon copies of the Registration Statement and the Prospectus, as filed with the Commission, including the exhibits thereto. We have also examined and relied upon the Sales Agreement, the Certificate of Incorporation of the Company (as amended or restated from time to time, the "Certificate of Incorporation"), the By-laws of the Company (as amended or restated from time to time, the "By-laws"), minutes of meetings and actions of the stockholders and the Board of Directors of the Company, including duly authorized committees thereof, as provided to us by the Company, certificates of representatives of the Company, certificates of public officials and such other documents as we have deemed necessary for purposes of rendering the opinions hereinafter set forth.

In our examination of the foregoing documents, we have assumed the genuineness of all signatures, the legal capacity of all signatories, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, the authenticity of such original documents and the completeness and accuracy of the corporate minute books of the Company. Further we have assumed that the Company will not issue and sell pursuant to the Sales Agreement such number of Shares that would cause the Company not to satisfy the eligibility requirements for Form S-3 (including, as applicable, Instruction I.B.6. thereof).

We have relied as to certain matters on information obtained from public officials and officers of the Company, and we have assumed that (i) the Shares will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement, the Prospectus and any applicable

prospectus supplement; (ii) there will be sufficient shares of Common Stock authorized under the Certificate of Incorporation and not otherwise reserved for issuance; (iii) if issued in uncertificated form, valid book entry notations for the issuance of the Shares will have been duly made in the share register of the Company and (iv) at the time of the issuance and sale of the Shares, the Company will be validly existing as a corporation and in good standing under the laws of the State of Delaware.

We have assumed that there will not have occurred, prior to the date of issuance of the Shares, any change in law affecting the validity of such Shares and that at the time of the issuance and sale of the Shares, the Board of Directors of the Company (or any committee of such Board of Directors or any person acting pursuant to authority properly delegated to such person by the Board of Directors of the Company or any committee of such Board of Directors) shall not have taken any action to rescind or otherwise reduce its prior authorization of the issuance of the Shares.

We express no opinion herein as to the laws of any state or jurisdiction other than the General Corporation Law of the State of Delaware. We also express no opinion herein with respect to compliance by the Company with the securities or "blue sky" laws of any state or other jurisdiction of the United States or of any foreign jurisdiction. In addition, we express no opinion and make no statement herein with respect to the antifraud laws of any jurisdiction.

Based upon and subject to the foregoing, we are of the opinion that the Shares have been duly authorized for issuance and, when the Shares are issued and paid for in accordance with the terms and conditions of the Sales Agreement, the Shares will be validly issued, fully paid and non-assessable.

It is understood that this opinion is to be used only in connection with the offer and sale of the Shares while the Registration Statement is in effect.

Please note that we are opining only as to the matters expressly set forth herein, and no opinion should be inferred as to any other matters. This opinion is based upon currently existing statutes, rules, regulations and judicial decisions, and we disclaim any obligation to advise you of any change in any of these sources of law or subsequent legal or factual developments which might affect any matters or opinions set forth herein.

We hereby consent to the filing of this opinion with the Commission in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act as an exhibit to the Current Report on Form 8-K to be filed by the Company on the date hereof in connection with the issuance and sale of the Shares and to the use of our name therein and in the related Prospectus Supplement under the caption "Legal Matters." In giving such consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.

<br>Very truly yours,

/s/ Wilmer Cutler Pickering Hale and Dorr LLP
