Item 7.01. Regulation FD Disclosure.

On May 14, 2024, Curis, Inc. (“Curis” or the “Company”) issued a press release announcing updated data from the ongoing TakeAim Leukemia study (CA-4948-102) in relapsed/refractory (“R/R”) Acute Myelogenous Leukemia (“AML”) to be presented at the American Society of Clinical Oncology (“ASCO”) and the European Hematology Association (“EHA”) conferences. The updated data includes data for 25 new patients in the FLT3 mutation (“FLT3m”) and U2AF1/SF3B1 Splicing Factor mutation (“SFm”) cohorts who had received fewer than 3 lines of prior therapy and were treated with emavusertib as monotherapy at the Recommended Phase 2 Dose (“RP2D”) of 300 mg twice daily (“BID”). The full text of the press release issued in connection with this announcement is attached as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

From time to time, the Company conducts meetings with third parties in which the Company utilizes a corporate slide presentation. A copy of the Company’s current corporate slide presentation is attached as Exhibit 99.2 to this Current Report on Form 8-K and incorporated herein by reference.

The information in this Item 7.01 (including Exhibits 99.1 and 99.2 attached hereto) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Item 8.01. Other Events.

TakeAim Leukemia Study

The updated data from the Company’s ongoing TakeAim Leukemia study (CA-4948-102) includes data for 25 new patients in the FLT3 mutation (FLT3m) and U2AF1/SF3B1 Splicing Factor mutation (SFm) cohorts who had received fewer than 3 lines of prior therapy and were treated with emavusertib as monotherapy at the Recommended Phase 2 Dose (RP2D) of 300 mg BID.

* data cut-off as of February 26, 2024
** 2 patients had both FLT3m and SFm (dual mutation)
1 patient in the initial group of 5 patients; 1 patient in the new group of 25 additional patients

FLT3m Cohort – 12 relapsed/refractory patients enrolled to date

12 R/R AML patients with FLT3m were treated with emavusertib. Prior therapies included venetoclax (8/12), hypomethylating agents or HMA (9/12), and FLT3 inhibitors (9/12). Preliminary data show 6 objective responses in 11 response-evaluable patients: 3 complete remission (CR), 1 CR with partial hematologic recovery (CRh) and 2 morphologic leukemia-free state (MLFS) with on-treatment duration range of 46-324 days. 4 patients are ongoing at the data-cutoff, including 1 CRh and 1 MLFS.

•3 of 3 patients who were naïve to FLT3i treatment achieved objective response (2 CR, 1 MLFS)
•3 of 8 patients who progressed on, or following, prior FLT3i treatment achieved objective response (1 CR, 1 CRh, 1 MLFS)
•1 patient is not response-evaluable



All responders demonstrated complete normalization of blast counts in the bone marrow. One of these patients proceeded to allogenic stem cell transplantation. Responses were achieved rapidly in this population, with 5 of 6 responses occurring within one cycle of treatment.

SFm Cohort – 20 relapsed/refractory patients enrolled to date

20 R/R AML patients with SFm were treated with emavusertib. Prior therapies included venetoclax (18/20) and HMA (17/20). Preliminary data show 4 of 18 response-evaluable patients in this population have achieved objective response (CR/CRh/MLFS). 8 of 20 patients are ongoing at the data-cutoff, including 1 MLFS and 3 non-responding patients who have shown increased neutrophil counts.

•All 4 responders (1 CR, 2 CRh, 1 MLFS) had received prior treatment with an HMA; 3 of whom had also received prior treatment with venetoclax
•3 additional non-responding patients are ongoing and have shown increased neutrophil counts
•2 patients are not response-evaluable

All responders demonstrated complete normalization of blast counts in the bone marrow. One of these patients proceeded to allogenic stem cell transplantation.

Cautionary Note Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, including, without limitation, any statements with respect to Curis's plans, strategies and objectives for emavusertib, its clinical trials and studies, commercialization plans, timelines, anticipated results or therapeutic potential, any statements regarding the initiation, progression, expansion, use, safety, efficacy, dosage and potential benefits of emavusertib in clinical trials as a monotherapy and/or as a combination therapy, Curis’s plans and timelines to provide preliminary, interim and/or additional data from its ongoing or planned clinical trials, its ability to further patient enrollment in its TakeAim Lymphoma, TakeAim Leukemia and AML triplet studies, any statements concerning Curis's expectations regarding its interactions with the FDA, statements with respect to mutations or potential biomarkers, and statements of assumptions underlying any of the foregoing. Forward-looking statements may contain the words "believes," "expects," "anticipates," "plans," "intends," "seeks," "estimates," "assumes," "predicts," "projects," "targets," "will," "may," "would," "could," "should," "continue," "potential," "focus," "strategy," "mission," or similar expressions. These forward-looking statements are not guarantees of future performance and involve risks, uncertainties, assumptions and other important factors that may cause actual results to be materially different from those indicated by such forward-looking statements. Curis may experience adverse results, delays and/or failures in its drug development programs and may not be able to successfully advance the development of its drug candidates in the time frames it projects, if at all. Curis's drug candidates may cause unexpected toxicities, fail to demonstrate sufficient safety and efficacy in clinical studies and/or may never achieve the requisite regulatory approvals needed for commercialization. Favorable results seen in preclinical studies and early clinical trials of Curis's drug candidates may not be replicated in later trials. Curis depends heavily on the success of emavusertib and any delays in the development of emavusertib could have a material adverse effect on its business. There can be no guarantee that the collaboration agreement with Aurigene will continue for its full term, or the CRADA with NCI, that Curis or its collaborators will each maintain the financial and other resources necessary to continue financing its portion of the research, development and commercialization costs, or that the parties will successfully discover, develop or commercialize drug candidates under the collaboration. Regulatory authorities may determine to delay or restrict Genentech's and/or Roche's ability to continue to commercialize Erivedge in basal cell carcinoma. Competing drugs may be developed that are superior to Erivedge. In connection with its agreement with Oberland Capital, Curis faces risks relating to the transfer and encumbrance of certain royalty and royalty-related payments on commercial sales of Erivedge, including the risk that, in the event of a default by Curis or its wholly-owned subsidiary, Curis could lose all retained rights to future royalty and royalty-related payments, Curis could be required to repurchase such future royalty and royalty-related payments at a price that is a multiple of the payments it has received, and its ability to enter into future arrangements may be inhibited, all of which could have a material adverse effect on its business, financial condition and stock price. Curis will require substantial additional capital to fund its business. Based on its available cash resources, it does not have sufficient cash on hand to support current operations within the next 12 months from the date of this Current Report on Form 8-K. If it is not able to obtain sufficient funding, it will be forced to delay, reduce in scope or eliminate its development of emavusertib, including related clinical trials and operating expenses, potentially delaying the time to market for, or preventing the marketing of, emavusertib, which could adversely affect its business prospects and its ability to continue operations, and would have a negative impact on its financial condition and its ability to pursue its business strategies. Curis faces substantial competition. Curis and its collaborators face the risk of potential adverse decisions made by the FDA and other regulatory authorities, investigational review boards, and publication review bodies.


Curis may not obtain or maintain necessary patent protection and could become involved in expensive and time-consuming patent litigation and interference proceedings. Unstable market and economic conditions, natural disasters, public health crises, political crises and other events outside of Curis's control could significantly disrupt its operations or the operations of third parties on which Curis depends and could adversely impact Curis's operating results and its ability to raise capital. Other important factors that may cause or contribute to actual results being materially different from those indicated by forward-looking statements include the factors set forth under the captions "Risk Factor Summary" and "Risk Factors" in our most recent Form 10-K and Form 10-Q, and the factors that are discussed in other filings that we periodically make with the Securities and Exchange Commission. In addition, any forward-looking statements represent the views of Curis only as of today and should not be relied upon as representing Curis's views as of any subsequent date. Curis disclaims any intention or obligation to update any of the forward-looking statements after the date of this Current Report on Form 8-K whether as a result of new information, future events or otherwise, except as may be required by law.
