Overview
Salarius is a clinical-stage biopharmaceutical company that has been focused on developing effective treatments for patients with cancer with high, unmet medical need. Specifically, Salarius has been concentrated on developing treatments for cancers caused by dysregulated gene expression (i.e., genes which are incorrectly turned on or off). Salarius has two classes of drugs that address gene dysregulation: targeted protein inhibitors and targeted protein degraders. Salarius’ technologies have the potential to work in both liquid and solid tumors. Salarius’ current pipeline consists of two small molecule drugs: (1) SP-3164, a targeted protein degrader, and (2) seclidemstat (“SP-2577”), a targeted protein inhibitor.
SP-3164
Salarius’ plan had been to develop SP-3164 in high unmet need hematological indications and solid tumors. Salarius’ goal was to file an investigational new drug (“IND”) application with the U.S. Food and Drug Administration (“FDA”) for SP-3164 in the first half of 2023, and begin a Phase 1/2 clinical trial in the second half of 2023, however the lack of funding required Salarius to curtail spending necessary to begin the clinical trial program.
SP-2577
On July 19, 2024, Salarius announced that it determined to close its ongoing Phase 1/2 clinical trial evaluating SP-2577 for Ewing sarcoma, including closing the remaining clinical trial sites. Salarius terminated the ongoing clinical trial in an effort to conserve cash. Salarius continues supporting The University of Texas MD Anderson Cancer Center (“MDACC”) in MDACC’s sponsored clinical trial evaluating SP-2577 in combination with azacytidine in adult patients with myelodysplastic syndromes and chronic myelomonocytic leukemia. In July 2024, the FDA placed the trial on partial clinical hold following a serious and unexpected grade 4 adverse event, encephalopathy, which was reversible. In February 2025, Salarius announced that MDACC had addressed the FDA’s questions and the partial clinical hold had been lifted, with patient enrollment resuming in the trial. Salarius has received FDA fast track designation for SP-2577 as a potential treatment for a rare pediatric disease in Ewing’s Sarcoma.
Recent Developments
Entry into Merger Agreement with Decoy Therapeutics, Inc. (“Decoy”)
On August 8, 2023, Salarius announced that it retained Canaccord Genuity, LLC to lead a comprehensive review of strategic alternatives focusing on maximizing stockholder value, including but not limited to, an acquisition, merger, reverse merger, divestiture of assets, licensing, or other strategic transactions involving the company. On January 10, 2025, Salarius entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Decoy Therapeutics MergerSub I, Inc., a Delaware corporation and a wholly owned subsidiary of Salarius (“First Merger Sub”), Decoy Therapeutics MergerSub II, LLC, a Delaware limited liability company and wholly owned subsidiary of Salarius (“Second Merger Sub”), and Decoy. Pursuant to the Merger Agreement, Salarius will combine with Decoy (the “Merger”) by causing First Merger Sub to be merged with and into Decoy, with Decoy surviving the merger as a wholly owned subsidiary of Salarius (the “First Merger”). Immediately following the First Merger, Decoy will merge with and into Second Merger Sub, with Second Merger Sub being the surviving entity and continuing under the name “Decoy Therapeutics, LLC” as a wholly owned subsidiary of Salarius.
The Merger is structured as a stock-for-stock transaction pursuant to which all of Decoy’s outstanding equity interests will be exchanged based on an exchange ratio for consideration of a combination of (a) shares of Salarius’ common stock par value $0.0001 (the “Common Stock”) in an amount up to (i) 19.9% of Salarius’ total shares outstanding as of January 10, 2025 minus (ii) any shares of Salarius Common Stock issued in any private placement between January 10, 2025 and the effective time of the First Merger (the “First Effective Time”), and (b) shares of Series A Preferred Stock, which is a newly designated series of preferred stock (“Preferred Stock”) that is
intended to have economic rights equivalent to the Common Stock, but with only limited voting rights, in addition to the assumption of outstanding and unexercised stock options to purchase shares of Common Stock from the Decoy Therapeutics Inc. 2020 Equity Incentive Plan. The number of shares of Common Stock to be issued at Merger Closing (as defined below) and the number of shares of Common stock underlying the Series A Preferred Stock to be issued at closing of the Merger (the “Merger Closing”) is based on an exchange ratio which assumes a base value of $28.0 million for Decoy and $4.6 million for Salarius, subject in each case to adjustment based on the balance sheet cash available to each of Salarius and Decoy at Merger Closing (excluding any proceeds raised the “Qualified Financing,” as defined below). Based on these relative values, before taking into account the dilutive effects of the Qualified Financing, Salarius’ legacy stockholders would retain approximately 14.1% of Salarius on an as-converted-to-common basis and, after giving effect to the exchange ratio and the conversion of the Series A Preferred Stock, Decoy stockholders would own approximately 85.9% of Salarius.
The rights of the Series A Preferred Stock will be set forth in a Certificate of Designation of Preferences, Rights and Limitations that Salarius will file with the Secretary of State of the State of Delaware (the “Certificate of Designation”). The Certificate of Designation provides that the preferred stock will be convertible into shares of Common Stock on a 1-for-1000 basis, subject to stockholder approval. The Merger was approved by Salarius’ board of directors and the board of directors of Decoy. In addition, following the consummation of the Merger, Salarius has agreed to call a special stockholder meeting to approve (i) the conversion of the preferred stock to be issued at Merger Closing into shares of Common Stock (the “Conversion Proposal”), (ii) a new equity incentive plan in form reasonably agreed to by the parties (the “Equity Plan Proposal”), and (iii) if necessary and advisable, a reverse stock split in a ratio to be approved by Salarius’ board of directors (the “Reverse Stock Split Proposal” and together with the Conversion Proposal and the Equity Plan Proposal, the “Company Stockholder Matters”).
The Merger Agreement contains customary representations and warranties by each of Salarius and Decoy, as well as covenants relating to operating each respective business in the ordinary course prior to Merger Closing. The Merger Closing is conditioned upon, among other things, minimum proceeds from future offerings of at least $6.0 million (collectively, the “Qualified Financing”) and the continued listing of Salarius Common Stock on Nasdaq. On January 17, 2025, Nasdaq notified Salarius that the proposed transaction with Decoy constitutes a business combination that will result in a “Change of Control” pursuant to Listing Rule 5110(a) and, accordingly, the post-transaction entity will be required to satisfy all of Nasdaq’s initial listing criteria and to complete Nasdaq’s initial listing process, including the payment of all applicable fees. Salarius intends to commence the process prior to seeking the Company’s stockholder approval for the issuance of 20% or more of the Company’s pre-transaction shares and must complete the process prior to the conversion of the preferred shares issued at the Merger Closing into shares of common stock of the Company.
In connection with the execution of the Merger Agreement, Salarius entered into stockholder support agreements (the “Salarius Support Agreements”) with certain of its officers and directors, who collectively own an aggregate of approximately 1.38% of the outstanding shares of the Common Stock. The Salarius Support Agreements provide that, among other things, each of the parties thereto has agreed to vote or cause to be voted all of the shares of Common Stock owned by such stockholder in favor of the Company Stockholder Matters at a special or annual meeting of Salarius’ stockholders to be held in connection therewith. In addition, Decoy officers and directors, in their capacities as stockholders of Decoy, entered into stockholder support agreements (the “Decoy Support Agreements”) with Decoy. The Decoy Support Agreements provide that, among other things, each of the parties thereto has agreed to vote or cause to be voted all of the shares of Common Stock owned by such stockholder in favor of the proposed Merger.
Concurrently and in connection with the execution of the Merger Agreement, certain Decoy officers and directors, and certain of Salarius’ directors and officers entered into lock-up agreements with Salarius and Decoy, pursuant to which each such stockholder will be subject to a 180-day lockup on the sale or transfer of shares of Common Stock held by each such stockholder at the Merger Closing, including those shares received by Decoy stockholders in the Merger.
Warrant Cancellation Agreement
On January 10, 2025, Salarius entered into a Warrant Cancellation Agreement (the “Warrant Cancellation Agreement”) with an accredited investor. Salarius previously issued to the investor a Series A-1 Common Stock Purchase Warrant to purchase 454,546 shares of its common stock pursuant to the offering described in Salarius’ Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on May 16, 2023 (the “Warrant”). Pursuant to the Warrant Cancellation Agreement, on January 10, 2025, Salarius paid the investor an aggregate amount in cash of $350,000 in exchange for the surrender and cancellation of the Warrant.
Securities ELOC Agreement
On December 12, 2024, Salarius entered into a securities purchase agreement (the “ELOC Agreement”) with C/M Capital Master Fund, LP (the “Purchaser”), pursuant to which Salarius, subject to the restrictions and satisfaction of the conditions in the ELOC Agreement, has the right, but not the obligation, to sell to the Purchaser, and the Purchaser is obligated to purchase, up to the lesser of (i) $10 million of newly issued shares (the “Purchase Shares”) of Salarius’ common stock and (ii) the Exchange Cap (as defined in the ELOC Agreement). As consideration for the Purchaser’s execution and delivery of the ELOC Agreement, Salarius has agreed to issue to the Purchaser, simultaneously with the delivery of any and all Purchase Shares purchased under the ELOC Agreement, a number of shares of Salarius common stock equal to one percent (1%) of the number of Purchase Shares actually sold in each sale under the ELOC Agreement.
Between January 13, 2025 and March 7, 2025, Salarius issued and sold 283,933 Purchase Shares to the Purchaser pursuant to the ELOC Agreement at a weighted average exercise price of $2.61 for an aggregate purchase price of $740,500. These issuances and sales were made following written notice delivered by Salarius to Investor, directing Investor to purchase the Purchase Shares. Salarius also issued 2,839 shares of its common stock to the Purchaser as commitment shares pursuant to the terms of the ELOC Agreement.
Program Development
SP-3164 - Targeted Protein Degradation
The field of targeted protein degradation (TPD) is rapidly growing. The two most common types of protein degraders are molecular glues (“MGs”) and proteolysis-targeting chimeras (PROTACs). SP-3164 is a next-generation cereblon-binding MG.
MGs are small molecules that commandeer the body’s normal protein degradation processes by causing proteins to stick to one another thereby inducing selective degradation of cancer-causing proteins. Derived from avadomide, SP-3164 is engineered using deuterium-enabled chiral switching , a process that replaces hydrogen atoms with deuterium to stabilize the molecule’s active enantiomer, resulting in a novel molecular entity with the potential for increased efficacy and improved safety compared to the first generation compound. SP-3164 degrades transcription factors IKZF1 (“Ikaros”) and IKZF3 (“Aiolos”), along with other proteins, resulting in both direct anti-cancer activity and immune-modulating properties.
Salarius’ plan had been to develop SP-3164 in high unmet need hematological indications and solid tumors. Salarius’ goal was to file an investigational new drug (“IND”) application with the United States Food and Drug Administration (“FDA”) for SP-3164 in the first half of 2023, and begin a Phase 1/2 clinical trial in the second half of 2023, however the lack of funding required Salarius to curtail spending necessary to begin the clinical trial program.
SP-2577 Ewing Sarcoma
Ewing sarcoma is a devastating pediatric and young adult cancer for which there are no approved targeted therapies. The cause of Ewing sarcoma is a chromosomal translocation involving the Ewing sarcoma breakpoint region 1 gene and ETS family genes, resulting in expression of a fusion oncoprotein. The resulting oncoprotein has been found to co-localize with LSD1 throughout the genome, making LSD1 an attractive therapeutic target for Ewing sarcoma.
On July 19, 2024, Salarius announced it had determined to close its ongoing Phase ½ clinical trial evaluating SP-2577 for Ewing sarcoma, including closing the remaining clinical trial sites.
SP-2577 Myelodysplastic Syndromes And Chronic Myelomonocytic Leukemia
Salarius intends to continue supporting The University of Texas MD Anderson Cancer Center (“MDACC”) in MDACC’s sponsored investigator-initiated clinical trial evaluating SP-2577 in combination with azacitidine in adult patients with myelodysplastic syndromes and chronic myelomonocytic leukemia. In July 2024, the FDA placed the trial on partial clinical hold following a serious and unexpected grade 4 adverse event, encephalopathy, which was reversible. In February 2025, Salarius announced that MDACC had addressed the FDA’s questions and the partial
clinical hold had been lifted, with patient enrollment resuming in the trial. We have received FDA fast track designation for SP-2577 as a potential treatment for a rare pediatric disease in Ewing’s Sarcoma.
Strategic Agreements
Listed below are the strategic agreements that may have an impact on our results of operations:
The University of Utah Research Foundation
On August 3, 2011, Salarius entered into an Exclusive License Agreement with the University of Utah Research Foundation (the “University of Utah”), for the exclusive license with respect to patent rights protecting SP-2577 and related compounds. The patent rights were for a provisional patent. The term of the agreement is until the last-to-expire of the patent rights licensed under the agreement, which is expected to be as late as 2037, unless otherwise terminated by law or by the parties pursuant to the agreement.
In further consideration of the rights granted by the University of Utah, Salarius agreed to pay all past patent expenses incurred in filing and prosecuting the patent application, and pay all future patent expenses incurred including filing, prosecuting, enforcing and maintaining the patent right.
Under the terms of the agreement, Salarius may be obligated to make certain future milestone and royalty payments, including: (i) an earned royalty payment based on a single digit percentage of net sales and a required minimum annual royalty payment commencing with the third full calendar year after the first commercial sale in the United States, Germany, France, Japan or the U.K. ranging from $10,000 to $40,000 per year which minimum payments are fully creditable towards the earned royalty payment with respect to the relevant calendar year, (ii) a sublicensee fee based on a single digit percentage of revenues received by sublicensees, (iii) milestone payments in agreed dollar amounts upon receiving regulatory approvals allowing the marketing and sale of licensed products or licensed methods relating to the patients’ rights in each of the United States, the European Union and Japan not exceeding $150,000 in the aggregate and (iv) a milestone payment in an agreed dollar amount upon the two year anniversary of the first commercial sale of a licensed product not exceeding $1.0 million.
Either party has a right to terminate the agreement for a breach of or default under the agreement following a 60-day cure period. If Salarius ceases to carry on its business with respect to the patent right granted under the agreement, the University of Utah has a right to terminate the agreement upon 60 days’ notice. In addition, Salarius may terminate the agreement at any time upon ninety days’ notice to the University of Utah.
Cancer Prevention and Research Institute of Texas
In June 2016, Salarius entered into a Cancer Research Grant Contract with Cancer Prevention and Research Institute of Texas (“CPRIT”). The grant contract was for an amount up to $18.7 million to fund the development of LSD-1 inhibitor. The grant was subsequently amended to remove $2.6 million related to a discontinued prostate cancer program. Salarius received approximately $16 million under the grant. The grant has been closed as of December 31, 2023.
DeuteRx, LLC
On January 12, 2022, Salarius entered into an acquisition and strategic collaboration agreement (the “ASCA”) with DeuteRx, LLC (“DeuteRx”), pursuant to which Salarius acquired targeted protein development portfolio.
The portfolio was purchased for an aggregate purchase price of $1.5 million and the delivery of 5,000 shares of Salarius’ common stock. Salarius agreed to pay to DeuteRx (i) milestone payments upon the occurrence of certain events and (ii) royalty payments. A member of Salarius’ board of directors also serves as a consultant to DeuteRx and is a consultant to an affiliate of DeuteRx.
Simultaneously with Salarius entry into the ASCA, Salarius and DeuteRx entered into the R&D Services Agreement, which sets forth the terms and conditions upon which DeuteRx will provide services to Salarius, including the implementation and performance of a Non-Clinical and Clinical Development Scope of Work. The ASCA remains in place, albeit at lower service levels resulting from company-wide cost cutting measures.
Manufacturing, Sales and Marketing
The Company currently has no manufacturing facilities, nor does it have a sales and marketing organization because our product candidates are still in preclinical or early-stage clinical development.
Intellectual Property
Salarius’ patent portfolio includes composition of matter and methods of use patents on Salarius’ candidate, SP-2577. In the United States, Salarius has two composition of matter patents and one methods of use patent with respect to SP-2577 and related compounds which will expire in 2032. The patents and patent applications related to SP-2577 are owned by the University of Utah Research Foundation and are exclusively licensed to Salarius.
Salarius also has patents with claims that cover the composition of matter of SP-3164 with a patent term expiration of January 14, 2034.
As of January 14, 2025, the targeted degradation patent portfolio consisted of 6 patent families with 17 granted patents and 4 pending applications acquired in the DeuteRx Transaction
In addition to patent protection, Salarius seeks to rely on trade secret protection, trademark protection and know-how to expand its proprietary position around its chemistry, technology and other discoveries and inventions that Salarius considers important to its business. Salarius also seeks to protect its intellectual property in part by entering into confidentiality agreements with employees, consultants, scientific advisors, clinical investigators and other contractors and by requiring employees, commercial contractors, and certain consultants and investigators, to enter into invention assignment agreements that grant Salarius ownership of any discoveries or inventions made by them. Further, Salarius seeks trademark protection in the United States and internationally where available and when Salarius deems appropriate.
Competition
SP-3164: Targeted Protein Degradation and Competitive Differentiation
The field of TPD is rapidly growing and attracting significant interest from the biggest pharmaceutical companies. The two most common types of protein degraders are molecular glues (“MGs”) and proteolysis-targeting chimeras (PROTACs). SP-3164 is a next-generation CRBN-binding MG. There are several MGs in clinical development and additional compounds in IND-enabling studies.
SP-2577: LSD1 Inhibition and Competitive Differentiation
LSD1 is a widely published epigenetic target and has attracted interest from several large pharmaceutical companies. LSD1 helps drive cancer progression through demethylation of histones and by acting as a scaffolding protein within various activator and repressor complexes.
Salarius believes that SP-2577 is differentiated in its ability to effectively inhibit LSD1’s scaffolding properties in addition to LSD1’s demethylation activity. Compared to irreversible LSD1 inhibitors, Salarius’ molecule has a novel binding mechanism (reversible as opposed to irreversible) and binding location (closer to substrate binding site as opposed to the FAD cofactor of LSD1).
Government Regulation and Product Approvals
United States Government Regulation
In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal Food, Drug, and Cosmetic Act, the FDA’s implementing regulations, and other federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, quality control, safety, effectiveness, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling and import and export of pharmaceutical products. We cannot market a drug product candidate in the United States until the drug has received FDA approval.
Drug Development Process
The process required before a drug may be marketed in the United States generally include the following:
•completion of extensive non-clinical laboratory tests and animal studies in accordance with the FDA’s Good Laboratory Practices (GLP) regulations, applicable requirements for the humane use of laboratory animals, such as the Animal Welfare Act or other applicable regulations;
•submission to the FDA of an Investigational New Drug (IND) for human clinical testing, which must be deemed effective before human clinical trials may begin;
•approval by an independent institutional review board (IRB) overseeing each clinical site before each trial may be initiated at that site;
•performance of adequate and well-controlled human clinical trials in accordance with Good Clinical Practices (GCP) requirements , and any additional requirements for the protection of human research subjects and their health information, to establish the safety and efficacy of the drug for each proposed indication;
•submission to the FDA of a New Drug Approval (NDA) for marketing approval that includes substantial evidence of safety and effectiveness from results of clinical trials, as well as the results of preclinical testing, detailed information about the chemistry, manufacturing and controls, and proposed labeling and packaging for the product candidate;
•consideration by an FDA Advisory Committee, if applicable;
•satisfactory completion of potential FDA audits of the preclinical study and clinical trial sites that generated the data in support of the NDA;
•satisfactory completion of an FDA pre-approval inspection of the nonclinical, clinical and/or manufacturing sites or facilities at which the active pharmaceutical ingredient, (API), and finished drug product are produced and tested to assess compliance with current Good Manufacturing Practices (cGMP); and
•FDA review and approval of the NDA prior to any commercial marketing or sale of the drug in the United States, including agreement on post-marketing commitments, if applicable.
Before testing any drugs with potential therapeutic value in humans, the drug enters the preclinical testing stage. Pre-clinical tests include laboratory evaluation of product chemistry, formulation and toxicity, as well as animal trials to assess the characteristics and potential safety and efficacy of the product. The conduct of the pre-clinical tests must comply with federal regulations and requirements, including GLP and the Animal Welfare Act.
Before commencing the first clinical trial in humans, an IND must be submitted to the FDA, and the IND must become effective. An IND sponsor must submit the results of pre-clinical testing to the FDA as part of an IND along with other information, including information about product chemistry, manufacturing and controls and a proposed clinical trial protocol. Long term pre-clinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted. A 30-day waiting period after the submission of each IND is required prior to the commencement of clinical testing in humans. If the FDA has neither commented on nor questioned the IND within this 30-day period, the clinical trial proposed in the IND may begin if all other requirements, including IRB review and approval, have been met. If the FDA raises concerns or questions about the conduct of the trial, such as whether human research subjects will be exposed to an unreasonable health risk, the IND sponsor and the FDA must resolve any outstanding FDA concerns or questions before clinical trials can proceed. Even after the IND has gone into effect and clinical testing has begun, the FDA may also impose clinical holds on clinical trials due to safety concerns or non-compliance. If the FDA imposes a clinical hold, studies may not recommence without FDA authorization and then only under terms authorized by the FDA.
Clinical trials involve the administration of the investigational new drug to healthy volunteers or patients under the supervision of a qualified investigator. Clinical trials must be conducted in compliance with state and federal regulations, including GCP requirements, which include the requirement that all research subjects provide their informed consent in writing for their participation in any clinical trial. Clinical trials are conducted under protocols detailing the objectives of the trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated, including stopping rules that assure a clinical trial will be stopped if certain adverse events (AEs) should occur. Each protocol and subsequent protocol amendments must be submitted to the FDA as part of the IND.
The FDA may order the temporary or permanent discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial either is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. The study protocol and informed consent information for
patients in clinical trials must also be submitted to an IRB, for approval of each site at which the clinical trial will be conducted. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the IRB’s requirements, or may impose other conditions. Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health (NIH) for public dissemination on their www.clinicaltrials.gov website.
Clinical trials to support NDAs for marketing approval are typically conducted in three sequential phases, but the phases may overlap. In Phase 1, the initial introduction of the drug into healthy human subjects or patients, the drug is tested to assess pharmacological actions, safety and side effects associated with increasing doses and, if possible, early evidence of effectiveness. Phase 2 usually involves trials in a larger but limited patient population to study metabolism of the drug, pharmacokinetics, the effectiveness of the drug for a particular indication, dosage tolerance and optimum dosage, and to identify common adverse effects and safety risks. If a compound demonstrates evidence of effectiveness and an acceptable safety profile in Phase 2 evaluations, Phase 3 clinical trials, also called pivotal trials, are undertaken to obtain the additional information about clinical efficacy and safety in a larger number of patients, typically at geographically dispersed clinical trial sites, to permit the FDA to evaluate the overall benefit-risk relationship of the drug and to provide adequate information for the labeling of the drug.
Post-approval studies, or Phase 4 clinical trials, may be conducted after initial marketing approval. These studies may be required by the FDA as a condition of approval and are used to gain additional experience from the treatment of patients in the intended therapeutic indication. The FDA has express statutory authority to require post-market clinical studies to address safety issues.
During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA. Written IND safety reports must be promptly submitted to the FDA and the investigators for serious and unexpected AEs, any findings from other studies, tests in laboratory animals or in vitro testing and other sources that suggest a significant risk for human subjects, or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that the information qualifies for reporting. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar days after the sponsor’s initial receipt of the information. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the biological product has been associated with unexpected serious harm to patients.
In limited circumstances, the FDA also permits the administration of investigational drug products to patients under its expanded access regulatory authorities. Under the FDA’s expanded access authority, patients who are not able to participate in a clinical trial may be eligible for accessing investigational products, including through individual compassionate or emergency use in concert with their requesting physician.
Concurrent with clinical trials, companies usually complete additional animal studies, develop additional information about the physical characteristics of the biological product candidate and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the biological product candidate does not undergo unacceptable deterioration over its shelf life.
FDA Review and Approval Process
After completion of the required clinical testing, a sponsor may prepare and submit an NDA to the FDA. FDA approval of the NDA is required before marketing of the product may begin in the United States. The NDA must include the results of all non-clinical, clinical and other testing and a compilation of data relating to the product’s toxicology, pharmacology, chemistry, manufacture and controls. In addition, under the Pediatric Research Equity Act, as amended, an NDA or supplement to an NDA generally must contain data to assess the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers depending on the designated pathway for submission. The cost of preparing and submitting an NDA is substantial. The submission of most NDAs is additionally subject to a substantial application user fee, and the manufacturer and/or sponsor under an approved NDA are also subject to annual product and establishment user fees. These fees are typically increased annually. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a
small business. Under the Prescription Drug User Fee Act (PDUFA) performance goals that are currently in effect, the FDA has a goal of ten months from the date of “filing” of a standard NDA for a new molecular entity to review and act on the submission. This review typically takes twelve months from the date the NDA is submitted to FDA, because the FDA has approximately two months to make a “filing” decision. That deadline can be extended under certain circumstances, including by the FDA’s requests for additional information. The targeted action date can also be shortened to 6 months of the “filing” date for products that are granted priority review designation because they are intended to treat serious or life-threatening conditions and demonstrate the potential to address unmet medical needs. Within 60 days following submission of the application, the FDA reviews all NDAs submitted to ensure that they are sufficiently complete for substantive review before it accepts them for filing. The FDA may issue a refuse-to-file letter and request additional information rather than accept an NDA for filing. In this event, the NDA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA reviews an NDA to determine, among other things, whether the drug is safe and effective and whether the facility(ies) in which it is manufactured, processed, packaged or held meets standards designed to assure the product’s continued safety, quality and purity. The FDA may also refer applications for novel drug products, or drug products that present difficult questions of safety or efficacy, to an advisory committee-typically a panel that includes clinicians and other experts-for consideration, discussion and a vote on specific questions relevant to the approval decision. The FDA is not bound by the recommendation of an advisory committee, but it considers such recommendations carefully when making decisions. Before approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCPs. Additionally, the FDA will inspect the facility or the facilities at which the drug is manufactured. The FDA will not approve the product unless compliance with cGMP requirements is satisfactory and the NDA contains data that provide substantial evidence that the drug is safe and effective in the indication studied.
During the NDA review process, the FDA also will determine whether a Risk Evaluation and Mitigation Strategy (REMS) is necessary to assure the safe use of the product. If the FDA concludes a REMS is needed, the sponsor must submit a proposed REMS; the FDA will not approve the NDA without a REMS, if required. A REMS could include a medication guide, communication plan or elements to assure safe use, such as required healthcare provider or pharmacy certification, a patient registry and other safe use conditions.
After the FDA evaluates the NDA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional clinical data , or information, in order to resubmit the application for another cycle of FDA review. If a complete response letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the complete response letter, or withdraw the application. If those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of information included.
An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. Even if the FDA approves a product, it may limit the approved indications for use of the product, require that contraindications, warnings or precautions be included in the product labeling, require that post- approval studies, including Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution and use restrictions or other risk management mechanisms under a REMS to ensure that the benefits of the drug outweigh the potential risks. The requirement for a REMS can materially affect the potential market and profitability of the drug. The FDA may prevent or limit further marketing of a product based on the results of post-marketing studies or surveillance programs. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained, FDA determines the risk outweighs the benefits of the product or other problems are identified following initial marketing.
Changes to some of the conditions established in an approved application, including changes in indications, labeling, or manufacturing processes or facilities, require submission and FDA approval of a new NDA or NDA supplement before the change can be implemented. An NDA supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA supplements as it does in reviewing NDAs. Such supplements are typically reviewed within 10 months of receipt or 6 months of receipt for priority efficacy supplements.
Orphan Drug Status
Under the Orphan Drug Act, the FDA may grant orphan drug designation to drug candidates intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that costs of research and development of the drug for the indication can be recovered by sales of the drug in the United States. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Although there may be some increased communication opportunities, orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.
If a drug candidate that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications, including a full NDA, to market the same drug for the same indication for seven years, except in limited circumstances, such as if the second applicant demonstrates the clinical superiority of its product or if FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug for the same disease or condition, or the same drug for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the NDA application user fee.
As in the United States, designation as an orphan drug for the treatment of a specific indication in the European Union, must be made before the application for marketing authorization is made. Orphan drugs in Europe enjoy economic and marketing benefits, including up to 10 years of market exclusivity for the approved indication unless another applicant can show that its product is safer, more effective or otherwise clinically superior to the orphan designated product.
The FDA and foreign regulators expect holders of exclusivity for orphan drugs to assure the availability of sufficient quantities of their orphan drugs to meet the needs of patients. Failure to do so could result in the withdrawal of marketing exclusivity for the orphan drug.
Expedited Development and Review Programs
The FDA has a Fast Track program that is intended to expedite or facilitate the process for development and review of new drug products that meet certain criteria. Specifically, new drug products are eligible for Fast Track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. Fast Track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a new drug may request that the FDA designate the drug as a Fast Track product at any time during the clinical development of the product. For a Fast Track-designated product, the FDA may consider for review sections of the marketing application on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the application, the FDA agrees to accept sections of the application and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the application. Fast Tack designation may be rescinded if FDA determines the program no longer meets the qualifying criteria for Fast Track.
Any product submitted to the FDA for marketing, including under a Fast Track program, may be eligible for other types of FDA programs intended to expedite development and review, such as priority review and accelerated approval. A product is eligible for priority review if it is intended to treat a serious condition and, if approved, would provide a significant improvement in safety or effectiveness. The FDA will attempt to direct additional resources to the evaluation of an application for a new drug product designated for priority review in an effort to facilitate the review on a 6 month, rather than the standard 10 month, timeline. We have received FDA designation as a potential treatment for a rare pediatric disease for the use of SP-2577 in Ewing’s Sarcoma. Should SP-2577 prove to be efficacious in this disease with a positive benefit/risk ratio, we expect to receive a Priority Review Voucher. The Priority Review Voucher is transferable and may be sold.
Additionally, a product may be eligible for accelerated approval under subpart H if it treats a serious or life-threatening disease or condition, provides meaningful advantage over existing treatments, and demonstrates an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit or on an intermediate clinical endpoint. If a product qualifies for accelerated approval, the product may be approved based on an effect on a surrogate endpoint or intermediate clinical endpoint that is reasonably likely to predict the drug’s clinical benefit. As a condition of accelerated approval, the FDA will require that a sponsor of a drug product subject to accelerated
approval perform an adequate and well-controlled post-marketing clinical trial to confirm clinical benefit. If a sponsor fails to conduct any required post-approval trial with “due diligence” FDA may withdraw the drug from the market. In addition, the FDA currently requires as a condition for accelerated approval that promotional materials be submitted in advance of initial dissemination, which could adversely impact the timing of the commercial launch of the product.
In addition, under the provisions of the FDA Safety and Innovation Act (FDASIA), the FDA established the Breakthrough Therapy Designation which is intended to expedite the development and review of products that treat serious or life-threatening diseases or conditions. A breakthrough therapy is defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all of the features of Fast Track designation, as well as more intensive FDA interaction and guidance. The Breakthrough Therapy Designation is distinct from both accelerated approval and priority review, but these can also be granted to the same product candidate if the relevant criteria are met. The FDA may take certain actions, such as holding timely meetings and providing advice, intended to expedite the development and review of an application for approval of a breakthrough therapy. Requests for breakthrough therapy designation will be reviewed within 60 days of receipt, and the FDA will either grant or deny the request. Breakthrough Therapy designation may be rescinded if the FDA determines the program no longer meets the qualifying criteria for breakthrough therapy.
Fast Track designation, priority review, accelerated approval and Breakthrough Therapy Designation do not change the standards for approval, but may expedite the development or approval process. Even if we receive Fast Track or Breakthrough designations for its product candidates, the FDA may later decide that its product candidates no longer meet the conditions for qualification. In addition, these designations may not provide us with a material commercial advantage.
Post-Approval Requirements
Once an NDA is approved, a product is subject to extensive continuing post-approval requirements. Any drug products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the drug, providing the FDA with updated safety and efficacy information, drug sampling and distribution requirements, complying with certain electronic records and signature requirements, and complying with FDA promotion and advertising requirements. For example, as a condition of approval of the NDA , the FDA may require post-marketing testing and surveillance to monitor the product’s safety or efficacy.
Adverse event reporting and submission of periodic reports is required following FDA approval of an NDA. The FDA also may require post-marketing testing, known as Phase 4 testing, REMS or other surveillance to monitor the effects of an approved product, or restrictions on the distribution or use of the product. In addition, quality control, drug manufacture, packaging and labeling procedures must continue to conform to cGMP after approval. Drug manufacturers and certain of their subcontractors are required to register their establishments with the FDA and certain state agencies. Registration with the FDA subjects’ entities to periodic unannounced inspections by the FDA, during which the agency inspects manufacturing facilities to assess compliance with cGMP. Accordingly, manufacturers must continue to expend time, money and effort in the areas of production and quality-control to maintain compliance with cGMP. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or failure to comply with regulatory requirements, may result in mandatory revisions to the approved labeling to add new safety information, imposition of post-market studies or clinical trials to assess new safety risks or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other things:
•restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;
•fines, untitled letters, warning letters or clinical holds on post-approval clinical trials;
•refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of product approvals; and
•product seizure or detention, or refusal to permit the import or export of products; or injunctions or the imposition of civil or criminal penalties.
The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability.
Foreign Regulation
In order to market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we would need to obtain the necessary approvals by the comparable foreign regulatory authorities before we can commence clinical trials or marketing of the product in foreign countries and jurisdictions.
Some countries outside of the United States have a similar process that requires the submission of a clinical trial application (CTA), much like the IND prior to the commencement of human clinical trials. In Europe, for example, a CTA must be submitted to a single EU portal for harmonized assessment at EU level with additional ethics review on each country’s national level, much like the FDA and an IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, a clinical trial may proceed in that country. To obtain regulatory approval to commercialize a new drug under European Union regulatory systems, we must submit a marketing authorization application (MAA). The MAA is similar to the NDA, with the exception of, among other things, country-specific document requirements.
Other Healthcare Laws
Although Salarius currently does not have any products on the market, Salarius’ current and future business operations may be subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which Salarius conducts its business. Such laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, privacy and security, price reporting and physician sunshine laws. Some of Salarius pre-commercial activities are subject to some of these laws.
Facilities
Our principal executive offices are in the Texas Medical Center in Houston, Texas, under a month-to-month lease. Currently, this facility consists of approximately 300 square feet and accommodates our general and administrative activities. We believe that our leased facility is adequate to meet our current needs.
Employees and Human Capital Resources
As of March 3, 2025, we had 2 full-time employees. We have never had a work stoppage, and none of our employees are represented by a labor organization or under any collective bargaining arrangements. We consider our employee relations to be good.
Legal Proceedings
We are not currently a party to any legal proceedings the outcome of which we believe, if determined adversely to us, would individually or in the aggregate, have a material adverse effect on our business, financial condition, or results of operations. From time to time, we may become involved in legal proceedings arising in the ordinary course of business.

ITEM 1A. RISK FACTORS
Item 1A. Risk Factors
The risk factors described below, as well as statements described elsewhere in this Annual Report on Form 10-K, including our audited Consolidated Financial Statements and the related notes and “Management’s Discussion and Analysis of Financial Conditions and Results of Operations”, or in other SEC filings, describe risks that could materially and adversely affect our business, financial condition, and results of operations, which could also cause the trading price of our equity securities to decline. These risks are not the only risks that we face. Our business, financial condition and results of operations could also be affected by additional factors that are not presently known to us or that we currently consider to be immaterial to our operations.
Risks Related to the Merger
The Merger may be completed even though certain events occur prior to Merger Closing that materially and adversely affect Salarius.
The Merger Agreement provides that either Salarius or Decoy can refuse to complete the Merger if there is a material adverse change affecting the other party between January 10, 2025, the date of the Merger Agreement, and the Merger Closing. However, certain types of changes do not permit either party to refuse to complete the Merger, even if such change could be said to have a material adverse effect on Salarius or Decoy, including:
•general business or economic conditions affecting the industry in which Salarius or Decoy or their subsidiaries, as applicable, operate;
•acts of war, armed hostilities or terrorism, acts of God or comparable events, epidemic, pandemic or disease outbreak (including the COVID-19 virus) or any worsening of the foregoing, or any declaration of martial law, quarantine or similar directive, policy or guidance or law or other action by any governmental body in response thereto;
•changes in financial, banking or securities markets;
•any change in, or any compliance with or action taken for the purpose of complying with, any law or generally accepted accounting principles (“GAAP”) (or interpretations of any law or GAAP);
•changes resulting from the announcement of the Merger Agreement or the pendency of the transactions contemplated by the Merger Agreement; or
•changes resulting from the taking of any action required to be taken under the Merger Agreement.
If adverse changes occur and Salarius and Decoy still complete the Merger, the market price of the combined company’s common stock may suffer. This in turn may reduce the value of the Merger to the stockholders of Salarius.
The Exchange Ratio set forth in the Merger Agreement is adjustable based on the Parent Cash Amount and the Company Cash Amount, each of which will be impacted by, among other things, unexpected expenses that could be experienced by Salarius or Decoy during the pre-Merger Closing period, which could result in Salarius stockholders owning significantly less of the combined company than currently estimated.
The Exchange Ratio formula in the Merger Agreement is subject to adjustment based on the Parent Cash Amount and Company Cash Amount on the anticipated Merger Closing Date (each as defined in the Merger Agreement). For example, if the Parent Cash Amount is $0 and the Company Cash Amount is $2.0 million, stockholders of Salarius would own approximately 14.1% of the fully diluted common stock, and stockholders of Decoy would own, or hold rights to acquire, approximately 85.9% of Salarius common stock, in each case calculated on a fully-diluted basis for in-the-money options and warrants (and in each case, prior to taking into account any dilution from the Qualified Financing). The calculation of the Exchange Ratio under the Merger Agreement and post-Merger Closing ownership of Salarius stockholders are subject to adjustment based on an assumed value of Salarius at Merger Closing based on the Parent Cash Amount and Company Cash Amount as of the anticipated Merger Closing Date. To the extent the Parent Cash Amount falls below $0, Salarius’ assumed value would be reduced or increased by
$100,000 for every $100,000 below the threshold. To the extent the Company Cash Amount falls below $2.0 million, Decoy’s assumed value would be reduced by $100,000 for every $100,000 below the threshold.
Based on Salarius’ current estimates, Salarius anticipates delivering a Parent Cash Amount of approximately $0; however, the final Parent Cash Amount will not be calculated until the anticipated Merger Closing Date, and may vary significantly depending on, among other things, Salarius’ ability to control and correctly estimate its operating expenses, and if the amount is significantly less, Salarius stockholders would experience additional dilution, subject to a floor of 10% of the combined company, regardless of the Parent Cash Amount on the anticipated Merger Closing Date. Further, these ownership percentages do not give effect to the shares of Salarius common stock that will be issued to investors in the Qualified Financing prior to the Merger Closing, and do not account for any additional shares of Salarius common stock that may be issued to investors following the effective time of the Merger. As a result, current stockholders of Salarius will own less of the combined company than currently contemplated.
Stockholders of the combined company may not realize a benefit from the Merger commensurate with the ownership dilution they will experience in connection with the Merger and the Qualified Financing.
If the combined company is unable to realize the full strategic and financial benefits currently anticipated from the Merger, Salarius stockholders and Decoy stockholders will have experienced substantial dilution of their ownership interests in their respective companies. The Qualified Financing will cause substantial dilution to Salarius and Decoy stockholders which may result in such stockholders not receiving any commensurate benefit, or only receiving part of the commensurate benefit to the extent the combined company is able to realize only part of the strategic and financial benefits currently anticipated from the Qualified Financing.
During the pendency of the Merger, Salarius may not be able to enter into a business combination with another party at a favorable price because of restrictions in the Merger Agreement, which could adversely affect its business.
Covenants in the Merger Agreement impede the ability of Salarius and Decoy to make acquisitions, subject to certain exceptions relating to fiduciary duties, as set forth below, or to complete other transactions that are not in the ordinary course of business pending completion of the Merger. As a result, if the Merger is not completed, the parties may be at a disadvantage to their competitors during such period. In addition, while the Merger Agreement is in effect, each party is generally prohibited from soliciting, initiating, encouraging or entering into certain extraordinary transactions, such as a merger, sale of assets, or other business combination outside the ordinary course of business with any third party, subject to certain exceptions relating to fiduciary duties. Any such transactions could be favorable to such party’s stockholders.
Certain provisions of the Merger Agreement may discourage third parties from submitting alternative takeover proposals, including proposals that may be superior to the arrangements contemplated by the Merger Agreement.
The terms of the Merger Agreement prohibit each of Salarius and Decoy from soliciting alternative takeover proposals or cooperating with persons making unsolicited takeover proposals, except in limited circumstances when such party’s board of directors determines in good faith that an unsolicited alternative takeover proposal is or is reasonably likely to lead to a superior takeover proposal and that failure to cooperate with the proponent of the proposal would be reasonably likely to be inconsistent with the applicable board’s fiduciary duties. Any such transactions could be favorable to such party’s stockholders. In addition, if Salarius terminates the Merger Agreement under certain circumstances, including terminating because of a decision of Salarius to enter into definitive agreement with respect to a superior offer, Salarius would be required to pay a termination fee of $300,000 to Decoy. This termination fee described above may discourage third parties from submitting alternative takeover proposals to Salarius stockholders.
Pursuant to the terms of the Merger Agreement, Salarius is required to recommend that its stockholders approve the conversion of all outstanding shares of its Series A Preferred Stock into shares of its Common Stock. Salarius cannot guarantee that its stockholders will approve this matter, and if they fail to do so its operations may be materially harmed.
Under the terms of the Merger Agreement, Salarius agreed following the consummation of the Merger to use reasonable best efforts to call and hold a meeting of Salarius stockholders to obtain the requisite approval for the conversion of all outstanding shares of Series A Preferred Stock issued in the Merger into shares of Salarius Common Stock, as required by the Nasdaq listing rules, as soon as practicable after the Merger Closing of the Merger and, if such approval is not obtained at that meeting, to seek to obtain such approval at an annual or special stockholders meeting to be held at least every four months thereafter until such approval is obtained, which would be time-consuming and costly and could significantly negatively affect Salarius’ projected cash position.
Because the lack of a public market for Decoy’s capital stock makes it difficult to evaluate the value of Decoy’s capital stock, the stockholders of Decoy may receive shares of Salarius common stock in the Merger that have a value that is greater than, the fair market value of Decoy’s capital stock.
The outstanding capital stock of Decoy is privately held and is not traded in any public market. The lack of a public market makes it extremely difficult to determine the fair market value of Decoy. Because the percentage of Salarius common stock to be issued to Decoy’s stockholders was determined based on negotiations between the parties, it is possible that Salarius may pay more than the aggregate fair market value for Decoy.
The combined company may become involved in securities class action litigation that could divert management’s attention and harm the combined company’s business and insurance coverage may not be sufficient to cover all costs and damages.
In the past, securities class action or shareholder derivative litigation often follows certain significant business transactions, such as the sale of a business division or announcement of a merger. The combined company may become involved in this type of litigation in the future. Litigation is often expensive and diverts management’s attention and resources, which could adversely affect the combined organization’s business.
The Merger Agreement between Salarius and Decoy may be terminated in accordance with its terms and the Merger may not be completed.
The Merger Agreement is subject to a number of conditions which must be fulfilled in order to complete the Merger. Those conditions include, among other things: (i) the lack of a Material Adverse Effect on the respective businesses of Salarius and Decoy; (ii) the continued listing of Salarius’ Common Stock on The Nasdaq Capital Market (“Nasdaq”) through the Merger Closing; (iii) the absence of any order, injunction, decree or other legal restraint preventing the consummation of the Merger or any of the other transactions contemplated by the Merger Agreement or making the completion of the Merger or any of the other transactions contemplated by the Merger Agreement illegal; (iv) completion of the Qualified Financing and (v) the accuracy of the respective parties’ representations and warranties contained in the Merger Agreement (subject to certain customary qualifications) and compliance by Salarius and Decoy with its respective agreements and covenants contained in the Merger Agreement.
These conditions to the Merger Closing may not be fulfilled in a timely manner or at all, and, accordingly, the Merger may not be completed. In addition, the parties can mutually decide to terminate the Merger Agreement at any time, or Salarius or Decoy may elect to terminate the Merger Agreement in certain other circumstances.
Salarius may not be able to effect the Merger pursuant to the Merger Agreement, and failure to complete the Merger would negatively impact Salarius’ stock price and materially adversely impact the future business and financial results of the Salarius.
In connection with the Merger Agreement, Salarius has incurred substantial costs planning and negotiating the transaction. These costs include, but are not limited to, costs associated with employing and retaining third-party advisors who performed the financial, auditing, and legal services required before Salarius was able to enter into the Merger Agreement and which will continue as Salarius seeks to complete the transaction. If, for whatever reason, including those set forth above, the transactions contemplated by the Merger Agreement fail to close, Salarius’ will be responsible for these costs, which could adversely affect Salarius liquidity and financial results. In addition, Salarius’ stock price may decline significantly if the Merger is not completed.
The market price of Salarius’ common stock following the Merger may decline as a result of the Merger.
The market price of Salarius’ common stock may decline as a result of the Merger for a number of reasons, including if:
•investors react negatively to the prospects of the combined company’s product candidates, business and financial condition following the Merger;
•the effect of the Merger on the combined company’s business and prospects is not consistent with the expectations of financial or industry analysts; or
•the combined company does not achieve the perceived benefits of the Merger as rapidly or to the extent anticipated by financial or industry analysts.
Salarius and Decoy securityholders will have a reduced ownership and voting interest in, and will exercise less influence over the management of, the combined company following the Merger Closing as compared to their current ownership and voting interest in the respective companies.
If the proposed Merger is completed, the current securityholders of Salarius and Decoy will own a smaller percentage of the combined company than their ownership in their respective companies prior to the Merger. Accordingly, the issuance of shares of Salarius common stock to Decoy’s stockholders in the Merger will reduce significantly the relative voting power of each share of Salarius common stock held by its current stockholders and will reduce the relative voting power of each share of Decoy common stock held by its current stockholders. Consequently, Salarius’ stockholders as a group and Decoy’s stockholders as a group will have less influence over the management and policies of the combined company after the Merger than prior to the Merger.
Consequently, securityholders of both Salarius and Decoy will be able to exercise less influence over the management and policies of the combined company following the Merger Closing than they currently exercise over the management and policies of their respective companies.
The combined company will need to raise additional capital by issuing securities or debt or through licensing or other strategic arrangements, which may cause dilution to the combined company’s stockholders or restrict the combined company's operations or impact its proprietary rights.
The combined company may be required to raise additional funds sooner than currently planned. If either or both of Salarius or Decoy hold less cash at the time of the Merger Closing than the parties currently expect, the combined company will need to raise additional capital sooner than expected. Additional financing may not be available to the combined company when it needs it or may not be available on favorable terms. To the extent that the combined company raises additional capital by issuing equity securities, such an issuance may cause significant dilution to the combined company’s stockholders’ ownership and the terms of any new equity securities may have preferences over the combined company’s common stock. Any debt financing the combined company enters into may involve covenants that restrict its operations. These restrictive covenants may include limitations on additional borrowing and specific restrictions on the use of the combined company’s assets, as well as prohibitions on its ability to create liens, pay dividends, redeem its stock or make investments. In addition, if the combined company raises additional funds through licensing, partnering or other strategic arrangements, it may be necessary to relinquish rights to some of the combined company’s technologies or product candidates and proprietary rights, or grant licenses on terms that are not favorable to the combined company.
Furthermore, provisions in the agreements for the Qualified Financing may deter or prevent the combined company from raising additional capital to fund the company as and when needed. Restrictive covenants and other provisions in the Qualified Financing documents could deter or prevent the combined company from raising additional capital as and when needed. The combined company’s failure to raise capital as and when needed would have a negative effect on its financial condition and its ability to develop and commercialize its pipeline and otherwise pursue the combined company’s business strategy and the combined company may be unable to continue as a going concern.
Risks Related to our Financial Position and Capital Needs
If the Merger is not completed, Salarius may not be able to otherwise source adequate liquidity to fund its operations, meet its obligations, and continue as a going concern. Salarius’ board of directors may decide to pursue a dissolution and liquidation of Salarius. In such an event, there can be no assurances as to the amount or timing of available cash left, if any, to distribute to its stockholders after paying its debts and other obligations and setting aside funds for reserves.
While Salarius has entered into the Merger Agreement with Decoy, the Merger Closing may be delayed or may not occur at all and there can be no assurance that the Merger will deliver the anticipated benefits Salarius expects or enhance stockholder value. If the Merger is not completed and the Merger Agreement is terminated under certain circumstances, Salarius may be required to pay Decoy a termination fee of $300,000. Even if a termination fee is not payable in connection with a termination of the Merger Agreement, Salarius will have incurred significant fees and expenses, which must be paid whether or not the Merger is completed.
Salarius does not currently have adequate financial resources to fund its forecasted operating costs for at least twelve months from the filing of this report. As of December 31, 2024, Salarius’ cash and cash equivalents totaled $2.4 million, which were held in bank deposit accounts and a money market account. As of December 31, 2024, Salarius has incurred an accumulated deficit of $81.9 million. For the twelve months ended December 31, 2024, Salarius reported net losses of $5.5 million. As of December 31, 2024, Salarius’ cash and cash equivalents totaled $2.4 million, which were held in bank deposit accounts and a money market account. As a result, Salarius believes its existing cash resources are sufficient to meet its anticipated needs into the later part of the second quarter of 2025. If for any reason the Merger does not close, Salarius would need to raise additional capital to continue to fund the further development of its product candidates and its operations thereafter. Salarius has based its cash sufficiency estimates on its current business plan and its assumptions may prove to be wrong. Salarius could utilize its available capital resources sooner than it currently expects, and it could need additional funding sooner than currently anticipated. Additionally, the process of advancing early stage product candidates and testing product candidates in clinical trials is costly, and the timing of progress in these clinical trials is uncertain. Even if Salarius raises sufficient funds and decides to continue the development of its product candidates, its ability to successfully transition to profitability will be dependent upon achieving a level of product sales adequate to support its cost structure. Salarius cannot assure you that it will ever be profitable or generate positive cash flow from operating activities.
Failure to secure any necessary financing in a timely manner and on favorable terms or the failure of the proposed Merger to be consummated in a timely manner would require Salarius to further delay or abandon any potential future clinical development plans. If, for any reason, the Merger does not close, the Salarius board of directors may elect to, among other things, attempt to complete another strategic transaction like the Merger, attempt to sell or otherwise dispose of the various assets of Salarius, resume its research and development activities and continue to operate the business of Salarius. Any of these alternatives would be costly and time-consuming and would require that Salarius obtain additional funding. Salarius expects that it would be difficult to secure financing in a timely manner, on favorable terms or at all. Salarius can make no assurances that it would be able to obtain additional financing or find a partner and close an alternative transaction on terms that are as favorable or more favorable than the terms set forth in the Merger Agreement or that any such alternatives are possible or would be successful, if pursued. To the extent that Salarius seeks and is able to raise additional capital through the sale of equity or convertible debt securities, Salarius’ stockholders’ ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect their rights as a common stockholder. Debt financing or preferred equity financing, if available, may involve agreements that include covenants limiting or restricting Salarius’ ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If Salarius raises funds through strategic transactions or marketing, distribution, or licensing arrangements with third parties, Salarius may have to relinquish valuable rights to its technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to it. Even if Salarius is able to pursue such alternatives, the failure to complete the Merger may result in negative publicity and/or a negative impression of Salarius in the investment community, could significantly harm the market price of Salarius common stock and may affect Salarius’ relationship with employees and other partners in the business community.
If the Salarius board of directors were to decide to dissolve and liquidate Salarius’ assets, Salarius would be required to pay all of its debts and contractual obligations, and to set aside certain reserves for potential future claims, and there can be no assurances as to the amount or timing of available cash left, if any, to distribute to stockholders after paying its debts and other obligations and setting aside funds for reserves. In addition, Salarius may be subject to litigation or other claims related to a dissolution and liquidation. If a dissolution and liquidation were pursued, the Salarius board of directors, in consultation with its advisors, would need to evaluate these matters and make a determination about a reasonable amount to reserve. Accordingly, Salarius’ stockholders would likely lose all or a significant portion of their investment in the event of a liquidation, dissolution or winding up of Salarius.
Salarius does not believe that its current expenses are indicative of the costs it may incur in the future in connection with the development and commercialization of any product candidate if it consummates the Merger or raises additional capital to continue its operations. Salarius’ future funding requirements will depend on many factors, including:
•its ability to consummate the Merger with Decoy;
•the scope, rate of progress and cost of its preclinical and clinical trials for any product candidate in its future pipeline and results of future clinical trials;
•the cost and timing of regulatory filings and approvals for any product candidates that successfully complete clinical trials;
•the timing and nature of any strategic transactions that Salarius undertakes, including potential partnerships;
•the effect of competing technological and market developments;
•the cost incurred in responding to actions by activist stockholders; and
•the cost of filing, prosecuting, defending and enforcing its intellectual property rights.
In addition, the amounts available under Salarius’ shelf registration statement on Form S-3 will be significantly limited as long as Salarius’ public float remains below $75 million, which, given its currently depressed stock price, limits its ability to obtain meaningful funding through a shelf registration statement at this time, although Salarius could still raise funds through a registration statement on Form S-1 or through private placements.
As such, there is uncertainty regarding Salarius’ ability to maintain liquidity sufficient to operate its business effectively, which raises substantial doubt about its ability to continue as a going concern.
Salarius’ common stock may be subject to delisting from Nasdaq, which would seriously harm the liquidity of our stock and our ability to raise capital or complete a strategic transaction.
Salarius’ common stock is currently listed on the Nasdaq Capital Market (“Nasdaq”). To maintain its listing on Nasdaq, Salarius is required to maintain: (i) a minimum bid price of $1.00 per share; (ii) a market value of publicly held securities of $1 million; (iii) a certain number of round lot stockholders; and (iv) one of the following: a net income from continuing operations (in the latest fiscal year or two of the three last fiscal years) of at least $500,000, a market value of listed securities of at least $35 million or a stockholders’ equity of at least $2.5 million (the “Stockholders’ Equity Requirement”). Nasdaq has the authority to delist Salarius’ common stock if Salarius fails to maintain these minimum requirements. In addition, Nasdaq may delist Salarius if, based on Nasdaq’s review of Salarius’ operations and pursuant to Nasdaq Listing Rule 5101, Nasdaq believes that Salarius is a “public shell” and that the continued listing of its securities is no longer warranted. Salarius has no current plans to delist its shares of common stock from Nasdaq. However, following the decision to close the clinical development of seclidemstat for Ewing sarcoma, Salarius may be treated as a public shell under Nasdaq rules. Although Nasdaq evaluates whether a listed company is a public shell company based on a facts and circumstances determination, a Nasdaq-listed company with no or nominal operations and either no or nominal assets, assets consisting solely of cash and cash equivalents, or assets consisting of any amount of cash and cash equivalents and nominal other assets is generally considered to be a public shell company. Listed companies determined to be public shell companies by Nasdaq may be subject to delisting proceedings or additional and more stringent listing criteria.
On August 9, 2024, Salarius reported in its Quarterly Report on Form 10-Q that as of June 30, 2024, its stockholders’ equity was approximately $2.3 million. As further disclosed in that Quarterly Report on Form 10-Q, subsequent to June 30, 2024, Salarius sold 564,730 shares of its common stock for gross proceeds of approximately $1.5 million pursuant to that certain At the Market Offering Agreement, dated as of February 5, 2021, with Ladenburg Thalmann & Co. Inc. (the “ATM Financing Transaction”). On August 13, 2024, Salarius reported via Current Report on Form 8-K that Salarius regained compliance with the Stockholders’ Equity Requirement after giving effect to the ATM Financing Transaction. Notwithstanding the foregoing, Nasdaq indicated that it would continue to monitor Salarius’ ongoing compliance with the Stockholders’ Equity Requirement and, if at the time of a future periodic report Salarius does not evidence compliance, Salarius’ common stock may be subject to delisting.
As of December 31, 2024, we had (i) a total stockholders’ equity of approximately $1.5 million, (ii) we have not had net income in any period during this fiscal year or either of the two last fiscal years and (iii) the market value of our
listed securities is below $35 million. As a result, Salarius is not in compliance with the Stockholders’ Equity Requirement and expects to receive a delisting notice from Nasdaq.
In addition, as of March 19, 2025, the closing price of Salarius’ common stock was $0.8615 per share. If Salarius’ common stock trades for thirty consecutive business days below the $1.00 minimum closing bid price requirement, Nasdaq will send a delisting determination to the company. If the delisting determination is sent within one year of Salarius’ most recent reverse stock split in June 2024, then Salarius will not be eligible for any compliance period to address the minimum bid price deficiency and will be subject to immediate delisting. Under these circumstances, Salarius can appeal the delisting determination to a Hearings Panel, during which time any suspension or delisting action will be stayed.
Salarius is actively monitoring the market value of its publicly held securities, its stockholders’ equity and trading prices and will consider any and all options available to it to maintain compliance. There can be no assurance, however, that Salarius will be able to maintain compliance and meet Nasdaq’s continued listing requirements.
If Salarius’ common stock is delisted from Nasdaq, whether because Nasdaq determines Salarius is a “public shell” or Salarius fails to maintain compliance with the continued listed requirements, or otherwise, Salarius’ securities may qualify for trading over-the-counter (“OTC”), in the United States on a market colloquially referred to as the “Pink Sheets.” Securities quoted on OTC are generally subject to lesser requirements than securities listed for trading on a U.S. national stock exchange, such as Nasdaq, including reduced corporate governance and public reporting standards. If Nasdaq should delist Salarius’ common stock from trading, a reduction in some or all of the following may occur, each of which could have a material adverse effect on holders of Salarius’ common stock: the liquidity of the common stock; the market price of the common stock; the number of institutional and general investors that will consider investing in the common stock; the number of investors in general that will consider investing in the common stock; the number of market makers in the common stock; the availability of information concerning the trading prices and volume of the common stock; and the number of broker-dealers willing to execute trades in the common stock. In addition to the foregoing, there are certain consequences under the Securities Act of 1933, as amended (the “Securities Act”), of being a public shell company, including the unavailability of Rule 144 thereunder for the resale of restricted securities and the inability to utilize Form S-8 for the registration of employee benefit plan securities.
In addition, if we cease to be eligible to trade on Nasdaq, we may have to pursue trading on a less recognized or accepted market, such as the over the counter markets, our stock may be traded as a “penny stock” which would make transactions in our stock more difficult and cumbersome, and we may be unable to access capital on favorable terms or at all, as companies trading on alternative markets may be viewed as less attractive investments with higher associated risks, such that existing or prospective institutional investors may be less interested in, or prohibited from, investing in our common stock. This may also cause the market price of our common stock to further decline.
Salarius is substantially dependent on its remaining employees and consultants to facilitate the consummation of the Merger.
As of March 12, 2025, Salarius had only two full-time employees and one consultant acting as Salarius’ Chief Executive Officer. Salarius’ ability to successfully complete the Merger depends in large part on its ability to retain certain remaining personnel. Despite Salarius’ efforts to retain these employees, one or more may terminate their employment or consulting arrangement with Salarius on short notice. The loss of the services of certain employees could potentially harm Salarius’ ability to consummate the Merger, to run its day-to-day business operations, as well as to fulfill its reporting obligations as a public company.
The pendency of the Merger could have an adverse effect on the trading price of Salarius’ common stock and its business, financial condition and prospects.
The pendency of the Merger could disrupt Salarius’ business in many ways, including:
•the attention of its remaining management and employees may be directed toward the completion of the Merger and related matters and may be diverted from Salarius’ day-to-day business operations; and
•third parties may seek to terminate or renegotiate their relationships with Salarius as a result of the Merger, whether pursuant to the terms of their existing agreements with Salarius or otherwise.
Should they occur, any of these matters could adversely affect the trading price of Salarius’ common stock or harm its business, financial condition and prospects.
Salarius has never generated any revenue from product sales and may never generate revenue or be profitable.
Salarius has no products approved for commercialization and has never generated any revenue. Salarius’ ability to generate revenue and achieve profitability depends on Salarius’ ability, alone or with strategic collaborators, to successfully complete the development of, and obtain the regulatory and marketing approvals necessary to commercialize one or more of its product candidates. Salarius does not anticipate generating revenue from product sales for the foreseeable future. Salarius’ ability to generate future revenue from product sales depends heavily on Salarius’ success in many areas, including but not limited to:
•completing research and development of its product candidates;
•obtaining regulatory and marketing approvals for its product candidates;
•manufacturing product candidates and establishing and maintaining supply and manufacturing relationships with third parties that are commercially feasible, meet regulatory requirements and supply needs in sufficient quantities to meet market demand for Salarius’ product candidates, if approved;
•marketing, launching and commercializing product candidates for which Salarius obtains regulatory and marketing approval, either directly or with a collaborator or distributor;
•gaining market acceptance of Salarius’ product candidates as treatment options;
•addressing any competing products;
•protecting and enforcing Salarius’ intellectual property rights, including patents, trade secrets, and know-how;
•negotiating favorable terms in any collaboration, licensing, or other arrangements into which Salarius may enter;
•obtaining reimbursement or pricing for Salarius’ product candidates that supports profitability; and
•attracting, hiring, and retaining qualified personnel.
Even if one or more of the product candidates that Salarius develops is approved for commercial sale, Salarius would need to incur significant costs associated with commercializing any approved product candidate. Portions of Salarius’ current pipeline of product candidates have been in-licensed from third parties, which make the commercial sale of such in-licensed products potentially subject to additional royalty and milestone payments to such third parties. Salarius will also have to develop, contract for or acquire manufacturing capabilities to continue development and potential commercialization of Salarius’ product candidates. Salarius will need to develop or procure its drug product in a commercially feasible manner in order to successfully commercialize any future approved product, if any. Additionally, if Salarius is not able to generate revenue from the sale of any approved products, Salarius may never become profitable.
Risks Related to the Development of Salarius’ Product Candidates
The approach Salarius has taken to discover and develop novel oncology therapeutics using epigenetic enzymes to moderate transcription factors and thereby control abnormal protein expression is unproven and may never lead to marketable products.
The scientific discoveries that have formed the basis for Salarius’ efforts to discover and develop Salarius’ product candidates are relatively recent. The scientific evidence to support the feasibility of developing drugs based on these discoveries is both preliminary and limited. The successful development of therapeutic products will require solving a number of issues. In addition, any product candidates that Salarius decides to develop further may not demonstrate in patients the chemical and pharmacological properties ascribed to them in laboratory and pre-clinical trials, and they may interact with human biological systems in unforeseen, ineffective or even harmful ways. For instance, Salarius’ clinical and pre-clinical data to date is not validated and Salarius has no way of knowing if after validation Salarius’ clinical trial data will be complete and consistent. If Salarius does not successfully develop and commercialize product candidates based upon this technological approach, Salarius may not become profitable and the value of Salarius’ capital stock may further decline.
Further, Salarius’ focus on epigenetic enzyme technology for developing product candidates as opposed to multiple, more proven technologies for drug development has increased the risk associated with Salarius’ business. Salarius is not able to identify and successfully implement an alternative product development strategy due to Salarius’ previous investments in current product candidates. In addition, work by other companies pursuing similar technologies may encounter setbacks and difficulties that regulators and investors may attribute to Salarius’ product candidates, whether appropriate or not.
Clinical trials are costly, time consuming and inherently risky, and may fail to demonstrate safety and efficacy to the satisfaction of applicable regulatory authorities.
Clinical development is expensive, time consuming and involves significant risk. If Salarius decides to move forward with Salarius’ clinical trials, Salarius cannot guarantee that they will be conducted as planned or completed on schedule, if at all. Salarius currently does not have the funds to advance Salarius’ planned clinical trials. A failure of one or more of these clinical trials can occur at any stage of development.
Salarius’ product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial viability of an approved label, or result in significant negative consequences following marketing approval, if any.
Undesirable side effects caused by Salarius’ product candidates could cause Salarius, an IRB or ethics committee, or regulatory authorities to continue the clinical hold status, interrupt, delay, or terminate clinical trials or even if approved, result in a restrictive label or delay regulatory approval by the FDA or comparable foreign authorities and potential product liability claims.
Product development involves a lengthy and expensive process with an uncertain outcome, and results of earlier pre-clinical and clinical trials may not be predictive of future clinical trial results.
Clinical testing is expensive and generally takes many years to complete, and the outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of pre-clinical trials and early clinical trials of Salarius’ product candidates may not be predictive of the results of larger, later-stage controlled clinical trials. Product candidates that have shown promising results in early-stage clinical trials may still suffer significant setbacks in subsequent clinical trials. Salarius’ clinical trials to date have been conducted on a small number of patients in limited numbers of clinical sites for a limited number of indications. Moreover, clinical data are often susceptible to varying interpretations and analyses. Salarius cannot assure whether any clinical trials Salarius or The University of Texas MD Anderson Cancer Center (“MDACC”) may conduct will demonstrate consistent or adequate efficacy and safety with respect to the proposed indication for use sufficient to receive regulatory approval or market Salarius’ drug candidates.
Difficulty in enrolling patients is a common hurdle faced by early stage biotechnology companies and could, and often does, delay or prevent clinical trials of product candidates.
Identifying and qualifying patients to participate in clinical trials of Salarius’ product candidates is essential to Salarius’ existence. The timing of Salarius’ clinical trials depends in part on the rate at which Salarius or investigators can recruit patients to participate in clinical trials of Salarius’ product candidates, and Salarius and Salarius’ investigators may experience delays in Salarius’ clinical trials if Salarius or they encounter difficulties in enrollment.
Salarius may face potential product liability, and, if successful claims are brought against Salarius, Salarius may incur substantial liability and costs which could be greater than Salarius’ insurance coverage or overall resources.
If the use or misuse of Salarius’ product candidates harms patients, or is perceived to harm patients even when such harm is unrelated to Salarius’ product candidates, Salarius’ regulatory approvals, if any, could be revoked or otherwise negatively impacted and Salarius could be subject to costly and damaging product liability claims. If Salarius is unable to obtain adequate insurance or are required to pay for liabilities resulting from a claim excluded from, or beyond the limits of, Salarius’ insurance coverage, a material liability claim could adversely affect Salarius’ financial condition.
The use or misuse of Salarius’ product candidates in clinical trials and the sale of any products for which Salarius may obtain marketing approval exposes Salarius to the risk of potential product liability claims. Product liability claims might be brought against Salarius by consumers, healthcare providers, pharmaceutical companies or others selling or otherwise coming into contact with Salarius’ product candidates and approved products, if any. There is a risk that Salarius’ product candidates may induce AEs.
Risks Related to Regulatory Approval of Salarius’ Product Candidates and Other Legal Compliance Matters
Even if FDA grants breakthrough therapy designation for one or more of Salarius’ product candidates, the designation may not lead to a faster development or regulatory review or approval process, and it does not increase the likelihood that Salarius’ product candidates will receive marketing approval, and FDA may rescind the designation if it determines the product candidate no longer meets the qualifying criteria for breakthrough therapy.
Salarius may seek a breakthrough therapy designation from the FDA for some of Salarius’ product candidates that reach the regulatory review process. A breakthrough therapy is defined as a drug or biological product that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug or biological product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For drugs or biological products that have been designated as breakthrough therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Drugs designated as breakthrough therapies by the FDA could also be eligible for accelerated approval.
Designation as a breakthrough therapy is within the discretion of the FDA. Accordingly, even if Salarius believes one of Salarius’ product candidates meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead determine not to make such designation.
The receipt of a breakthrough therapy designation for a product candidate may not result in a faster development process, review or approval compared to drugs considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if one or more of Salarius’ product candidates qualify and are designated as breakthrough therapies, the FDA may later decide that the drugs or biological products no longer meet the conditions for designation and the designation may be rescinded.
Salarius has received fast track designation for SP-2577 as a potential treatment for a rare pediatric disease in Ewing’s Sarcoma, but such designation may not actually lead to a faster development or regulatory review or approval process. Additionally, FDA may rescind the designation if it determines the product candidate no longer meets the qualifying criteria for fast track.
If a product candidate is intended for the treatment of a serious condition and nonclinical or clinical data demonstrate the potential to address unmet medical need for this condition, a product sponsor may apply for FDA fast track designation. Salarius received fast track designation for SP-2577 as a potential treatment for a rare pediatric disease in Ewing’s Sarcoma. However, fast track designation does not ensure that Salarius will receive marketing approval or that approval will be granted within any particular time frame. Salarius may not experience a faster development or regulatory review or approval process with fast track designation compared to conventional FDA procedures. In addition, the FDA may withdraw fast track designation if it believes that the designation is no longer supported by data from Salarius’ clinical development program. Fast track designation alone does not guarantee qualification for the FDA’s priority review procedures.
Salarius cannot guarantee how long it will take regulatory agencies to review Salarius’ applications for product candidates, and Salarius may fail to obtain the necessary regulatory approvals to market Salarius’ product candidates. If Salarius is not able to obtain required regulatory approvals, Salarius will not be able to commercialize Salarius’ product candidates and Salarius’ ability to generate revenue will be materially impaired.
Salarius’ product candidates and the activities associated with their development and commercialization, including their design, research, testing, manufacture, safety, efficacy, recordkeeping, labeling, packaging, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA and other
regulatory agencies in the United States and foreign jurisdictions. Failure to obtain marketing approval for Salarius’ product candidates will prevent Salarius from commercializing them in those markets.
Salarius has not received approval from regulatory authorities to market any product candidate in any jurisdiction, and it is possible that neither Salarius’ current product candidates nor any product candidates that Salarius may seek to develop in the future will ever obtain the appropriate regulatory approvals necessary for Salarius to commence product sales.
Reliance on government funding for Salarius’ programs may add uncertainty to Salarius’ research and commercialization efforts with respect to those programs that are tied to such funding and may impose requirements that limit Salarius’ ability to take specified actions, increase the costs of commercialization and production of product candidates developed under those programs and subject Salarius to potential financial penalties, which could materially and adversely affect Salarius’ business, financial condition and results of operations.
During the course of Salarius’ development of Salarius’ product candidates, Salarius has been funded in part through federal and state grants, including but not limited to the funding Salarius received from the Cancer Prevention and Research Institute of Texas (“CPRIT”). If Salarius does not comply with the terms of the grant, CPRIT may require Salarius to repay some or all of the disbursed grant.
Risks Related to Salarius’ Intellectual Property
Salarius may not be successful in obtaining or maintaining necessary rights to Salarius’ targets, product compounds and processes for Salarius’ development pipeline through acquisitions and in-licenses.
Presently, Salarius has rights to the intellectual property, through licenses from third parties and under patents and patent applications that Salarius owns, to modulate only a subset of the known epigenetic enzyme targets. Because Salarius’ programs may involve a range of targets, including targets that require the use of proprietary rights held by third parties, the growth of Salarius’ business may depend in part on Salarius’ ability to acquire, in-license or use these proprietary rights. In addition, Salarius’ product candidates may require specific formulations to work effectively and efficiently and these rights may be held by others. Salarius may be unable to acquire or in-license any compositions, methods of use, processes or other third-party intellectual property rights from third parties that Salarius identify. The licensing and acquisition of third-party intellectual property rights is a competitive area, and a number of more established companies are also pursuing strategies to license or acquire third-party intellectual property rights that Salarius may consider attractive. These established companies may have a competitive advantage over Salarius due to their size, cash resources and greater clinical development and commercialization capabilities.
For example, Salarius has previously collaborated with academic institutions worldwide to accelerate Salarius’ pre-clinical and clinical research or development under written agreements with these institutions. Typically, these institutions provide an option to negotiate a license to any of the institution’s rights in technology resulting from the collaboration. Regardless of such right of first negotiation for intellectual property, Salarius may be unable to negotiate a license within the specified time frame or under terms that are acceptable to Salarius. If Salarius is unable to do so, the institution may offer the intellectual property rights to other parties, potentially blocking Salarius’ ability to pursue its program.
In addition, companies that perceive Salarius to be a competitor may be unwilling to assign or license rights to Salarius. Salarius also may be unable to license or acquire third-party intellectual property rights on terms that would allow Salarius to make an appropriate return on Salarius’ investment. If Salarius is unable to successfully obtain rights to third-party intellectual property rights, Salarius’ business, financial condition and prospects for growth could suffer.
Salarius intends to rely on patent rights for Salarius’ product candidates and any future product candidates. If Salarius is unable to obtain or maintain exclusivity from the combination of these approaches, Salarius may not be able to compete effectively in Salarius’ markets.
Salarius relies or will rely upon a combination of patents, trade secret protection, and confidentiality agreements to protect the intellectual property related to Salarius’ technologies and product candidates. Salarius’ success depends in large part on Salarius’ and its licensors’ ability to obtain regulatory exclusivity and maintain patent and other
intellectual property protection in the United States and in other countries with respect to Salarius’ proprietary technology and products.
Salarius has sought to protect Salarius’ proprietary position by filing patent applications in the United States and abroad related to Salarius’ product candidates that are important to Salarius’ business. This process is expensive and time consuming, and Salarius may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that Salarius will fail to identify patentable aspects of Salarius’ research and development output before it is too late to obtain patent protection.
The patent position of biotechnology and pharmaceutical companies generally is highly uncertain and involves complex legal and factual questions for which legal principles remain unsolved. The patent applications that Salarius owns or in-licenses may fail to result in issued patents with claims that cover Salarius’ product candidates in the United States or in other foreign countries. There is no assurance that all potentially relevant prior art relating to Salarius’ patents and patent applications has been found, which can invalidate a patent or prevent a patent from issuing from a pending patent application. Even if patents do successfully issue, and even if such patents cover Salarius’ product candidates, third parties may challenge their validity, enforceability, or scope, which may result in such patents being narrowed, found unenforceable or invalidated. Furthermore, even if they are unchallenged, Salarius’ patents and patent applications may not adequately protect Salarius’ intellectual property, provide exclusivity for Salarius’ product candidates, or prevent others from designing around Salarius’ claims. Any of these outcomes could impair Salarius’ ability to prevent competition from third parties, which may have an adverse impact on Salarius’ business.
Salarius, independently or together with Salarius’ licensors, have filed several patent applications covering various aspects of Salarius’ product candidates. Salarius cannot offer any assurances about which, if any, patents will issue, the breadth of any such patent or whether any issued patents will be found invalid and unenforceable or will be threatened by third parties. Any successful opposition to these patents or any other patents owned by or licensed to Salarius after patent issuance could deprive Salarius of rights necessary for the successful commercialization of any product candidates that Salarius may develop. Further, if Salarius encounters delays in regulatory approvals, the period of time during which Salarius could market a product candidate under patent protection could be reduced.
If Salarius cannot obtain and maintain effective protection of exclusivity from Salarius’ regulatory efforts and intellectual property rights, including patent protection or data exclusivity, for Salarius’ product candidates, Salarius may not be able to compete effectively and Salarius’ business and results of operations would be harmed.
Salarius may not have sufficient patent term protections for Salarius’ product candidates to effectively protect Salarius’ business.
Patents have a limited term. In the United States, the statutory expiration of a patent is generally 20 years after it is filed. Although various extensions may be available, the life of a patent, and the protection it affords, is limited. Even if patents covering Salarius’ product candidates are obtained, once the patent life has expired for a product candidate, Salarius may be open to competition from generic medications. In addition, upon issuance in the United States any patent term can be adjusted based on specified delays caused by the applicant(s) or the U.S. Patent and Trademark Office (the “USPTO”).
Depending on the timing, duration, and conditions of FDA marketing approval of Salarius’ product candidates, one or more of Salarius’ United States patents may be eligible for patent term extension under the Hatch-Waxman Act. Patent term extensions under the Hatch-Waxman Act in the United States and under supplementary protection certificates in Europe may be available to extend the patent or data exclusivity terms of Salarius’ product candidates. Salarius will likely rely on patent term extensions, and Salarius cannot provide any assurances that any such patent term extensions will be obtained and, if so, for how long. However, Salarius may not receive an extension if Salarius fails to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than Salarius requests. If Salarius is unable to obtain patent term extension or the term of any such extension is less than Salarius requests, the period during which Salarius can enforce Salarius’ patent rights for that product may not extend beyond the current patent expiration dates and competitors may obtain approval to market competing products sooner. As a result, Salarius may not be able to maintain exclusivity for Salarius’ product candidates for an extended period after regulatory approval, if any, which would negatively impact Salarius’ business, financial condition, results of operations and prospects. If Salarius does not have sufficient patent terms or regulatory
exclusivity to protect Salarius’ product candidates, Salarius’ business and results of operations will be adversely affected.
Changes in U.S. patent law could diminish the value of patents in general, thereby impairing Salarius’ ability to protect Salarius’ products, and recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of Salarius’ patent applications and the enforcement or defense of Salarius’ issued patents.
As is the case with other biotechnology companies, Salarius’ success is heavily dependent on patents and the ability to enforce and protect these patients. Obtaining and enforcing patents in the biotechnology industry involve both technological and legal complexity, and is therefore costly, time-consuming and inherently uncertain. In addition, the United States has recently enacted and is currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in specified circumstances and weakened the rights of patent owners in specified situations. In addition to increasing uncertainty with regard to Salarius’ ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken Salarius’ ability to obtain new patents or to enforce Salarius’ existing patents and patents that Salarius might obtain in the future. Some of Salarius’ patent claims may be affected by the recent U.S. Supreme Court decision in Association for Molecular Pathology v. Myriad Genetics. In Myriad, the Supreme Court held that unmodified isolated fragments of genomic sequences, such as the DNA constituting the BRCA1 and BRCA2 genes, are not eligible for patent protection because they constitute a product of nature. The exact boundaries of the Supreme Court’s decision remain unclear as the Supreme Court did not address other types of nucleic acids.
If Salarius is unable to maintain effective proprietary rights for Salarius’ product candidates or any future product candidates, Salarius may not be able to compete effectively in Salarius’ proposed markets.
In addition to the protection afforded by patents, Salarius relies on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable or that Salarius elects not to patent, processes for which patents are difficult to enforce and any other elements of Salarius’ product candidate discovery and development processes that involve proprietary know-how, information or technology that is not covered by patents. However, trade secrets can be difficult to protect. Salarius seek to protect Salarius’ proprietary technology and processes, in part, by entering into confidentiality agreements with Salarius’ employees, consultants, scientific advisors, and contractors. Salarius also seeks to preserve the integrity and confidentiality of Salarius’ data and trade secrets by maintaining physical security of Salarius’ premises and physical and electronic security of Salarius’ information technology systems. While Salarius has confidence in these individuals, organizations and systems, agreements or security measures may be breached, and Salarius may not have adequate remedies for any breach. In addition, Salarius’ trade secrets may otherwise become known or be independently discovered by competitors.
Third-party claims of intellectual property infringement may prevent or delay Salarius’ development and commercialization efforts.
Salarius’ commercial success depends in part on Salarius’ ability to develop, manufacture, market and sell Salarius’ product candidates and use Salarius’ proprietary technology without infringing the patent rights of third parties.
Numerous third-party U.S. and non-U.S. issued patents and pending applications exist in the area of epigenetic enzyme inhibitors and related technologies. Salarius is aware of U.S. and foreign patents and pending patent applications owned by third parties that cover therapeutic uses of epigenetic inhibitors. Salarius is currently monitoring these patents and patent applications. Salarius may in the future pursue available proceedings in the U.S. and foreign patent offices to challenge the validity of these patents and patent applications. In addition, or alternatively, Salarius may consider whether to seek to negotiate a license of rights to technology covered by one or more of such patents and patent applications. If any patents or patent applications cover Salarius’ product candidates or technologies, Salarius may not be free to manufacture or market Salarius’ product candidates, as planned, absent such a license, which may not be available to Salarius on commercially reasonable terms, or at all.
Salarius may not be successful in meeting Salarius’ obligations under Salarius’ existing license agreements necessary to maintain Salarius’ product candidate licenses in effect. In addition, if required in order to commercialize Salarius’ product candidates, Salarius may be unsuccessful in obtaining or maintaining necessary rights to Salarius’ product candidates through acquisitions and in-licenses.
Salarius currently has rights to the intellectual property, through licenses from third parties and under patents that Salarius does not own, to develop and commercialize Salarius’ product candidates. Because Salarius’ programs may require the use of proprietary rights held by third parties, the growth of Salarius’ business will likely depend in part on Salarius’ ability to maintain in effect these proprietary rights. Any termination of license agreements with third parties with respect to Salarius’ product candidates would be expected to negatively impact Salarius’ business prospects.
Salarius may be unable to acquire or in-license any compositions, methods of use, processes, or other third-party intellectual property rights from third parties that Salarius identifies as necessary for Salarius’ product candidates.
If Salarius fails to comply with obligations in the agreements under which Salarius licenses intellectual property and other rights from third parties or otherwise experience disruptions to Salarius’ business relationships with Salarius’ licensors, Salarius could lose license rights that are important to Salarius’ business.
Salarius is a party to intellectual property licenses and supply agreements that are important to Salarius’ business and may enter into additional license agreements in the future. Salarius’ existing agreements impose, and Salarius expects that future license agreements will impose on Salarius, various diligence, milestone payment, royalty, purchasing, and other obligations. If Salarius fails to comply with Salarius’ obligations under these agreements, or Salarius is subject to a bankruptcy, Salarius’ agreements may be subject to termination by the licensor, in which event Salarius would not be able to develop, manufacture, or market products covered by the license or subject to supply commitments.
Salarius may be involved in lawsuits to protect or enforce Salarius’ patents or the patents of Salarius’ licensors, which could be expensive, time consuming, and unsuccessful.
Competitors may infringe Salarius’ patents or the patents of Salarius’ licensors. If Salarius or one of Salarius’ licensing partners were to initiate legal proceedings against a third party to enforce a patent covering one of Salarius’ product candidates, the defendant could counterclaim that the patent covering Salarius’ product candidate is invalid and/or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, written description, clarity or non- enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. The outcome following legal assertions of invalidity and unenforceability is unpredictable.
Salarius may not be able to protect Salarius’ intellectual property rights throughout the world.
Filing, prosecuting, and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and Salarius’ intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Competitors may use Salarius’ technologies in jurisdictions where Salarius has not obtained patent protection to develop Salarius’ own products and may also export infringing products to territories where Salarius has patent protection, but enforcement is not as strong as that in the United States. These products may compete with Salarius’ products and Salarius’ patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.
Risks Related to Salarius’ Reliance on Third Parties
Salarius relies on or will rely on third parties to conduct Salarius’ clinical trials. If these third parties do not successfully perform and comply with regulatory requirements, Salarius may not be able to successfully complete clinical development, obtain regulatory approval or eventually commercialize Salarius’ product candidates and Salarius’ business could be substantially harmed.
Salarius has relied upon and plan to continue to rely upon third-parties such as contract research organizations (“CROs”), hospitals and clinical investigators to study Salarius’ product candidates in clinical trials. For example, Salarius has collaborated with The University of Texas MD Anderson Cancer Center (“MDACC”) to study SP-2577 in combination with azacitidine for the treatment of patients with myelodysplastic syndromes or chronic
myelomonocytic leukemia . Salarius relies on these parties for the execution of clinical trials and Salarius only manages and controls some aspects of their activities. With respect to the MDACC sponsored investigator initiated trial, Salarius supplies seclidemstat in quantities required to conduct the clinical trial, but does not have any control over their development activities or the timing thereof. Salarius remains responsible for ensuring that each of Salarius’ trials is conducted in accordance with the applicable protocol, legal, regulatory, and scientific standards and Salarius’ reliance on these third parties does not relieve Salarius of its regulatory responsibilities. In July 2024, the FDA placed the trial on partial clinical hold following a serious and unexpected grade 4 adverse event encephalopathy, which was reversible. In February 2025, Salarius announced that MDACC had addressed the FDA’s questions and the partial clinical hold had been lifted, with patient enrollment resuming in the trial.
Salarius expects to rely on third parties to manufacture Salarius’ clinical product supplies, and Salarius intends to rely on third parties to produce and process Salarius’ product candidates, if approved, and Salarius’ commercialization of any of Salarius’ product candidates could be stopped, delayed or made less profitable if those third parties fail to obtain approval of government regulators, fail to comply with applicable regulations, fail to provide Salarius with sufficient quantities of drug product, or fail to do so at acceptable quality levels or prices.
Salarius does not currently have nor does Salarius currently plan to develop the infrastructure or capability internally to manufacture Salarius’ clinical supplies for use in the conduct of Salarius’ clinical trials, and Salarius lacks the resources and the capability to manufacture any of Salarius’ product candidates on a clinical or commercial scale. Salarius currently relies on outside vendors to manufacture the clinical supplies of Salarius’ product candidates. Salarius plans to continue relying on third parties to manufacture Salarius’ product candidates on a commercial scale, if approved.
Salarius does not yet have sufficient information to reliably estimate the cost of the commercial manufacturing of Salarius’ product candidates and Salarius’ current costs to manufacture Salarius’ drug products is not commercially feasible, and the actual cost to manufacture Salarius’ product candidates could materially and adversely affect the commercial viability of Salarius’ product candidates. As a result, Salarius may never be able to develop a commercially viable product.
Risks Related to Our Common Stock
Future sales of a significant number of our shares of common stock in the public markets, or the perception that such sales could occur, could depress the market price of our shares of our common stock or cause our stock price to decline.
Sales of a substantial number of our shares of common stock in the public markets, or the perception that such sales could occur, including from the exercise of warrants or sales of common stock issuable thereunder, could cause the market price of our shares of common stock to decline and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the number of these shares that might be sold nor the effect that future sales of our shares of common stock, including shares issuable upon the exercise of warrants, would have on the market price of our shares of common stock.
We do not currently intend to pay dividends on our common stock, and any return to investors is expected to come, if at all, only from potential increases in the price of our common stock.
At the present time, we intend to use available funds to finance our operations. Accordingly, while payment of dividends rests within the discretion of our board of directors, we have no intention of paying any such dividends in the foreseeable future. Any return to investors is expected to come, if at all, only from potential increases in the price of our common stock.
General Risk Factors
Failure in our information technology and storage systems could significantly disrupt the operation of our business and/or lead to potential large liabilities.
Our ability to execute our business plan and maintain operations depends on the continued and uninterrupted performance of our information technology systems. Information technology systems are vulnerable to risks and damages from a variety of sources, including telecommunications or network failures, malicious human acts and
natural disasters. Moreover, despite network security and back-up measures, some of our and our vendors’ servers are potentially vulnerable to physical or electronic break-ins, including cyber-attacks, computer viruses and similar disruptive problems. These events could lead to the unauthorized access, disclosure and use of non-public information which in turn could lead to operational difficulties and liabilities.
A security breach or privacy violation that leads to disclosure of consumer, customer, supplier, partner or employee information (including personally identifiable information or protected health information) could harm our reputation, compel us to comply with disparate state and foreign breach notification laws and otherwise subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue.
The techniques used by criminal elements to attack computer systems are sophisticated, change frequently and may originate from less regulated and remote areas of the world. As a result, we may not be able to address these techniques proactively or implement adequate preventative measures. If our computer systems are compromised, we could be subject to fines, damages, litigation and enforcement actions, and we could lose trade secrets, the occurrence of which could harm our business. Despite precautionary measures to prevent unanticipated problems that could affect our information technology systems, sustained or repeated system failures that interrupt our ability to generate and maintain data could adversely affect our ability to operate our business. In addition, a data security breach could distract management or other key personnel from performing their primary operational duties.
The interpretation and application of consumer and data protection laws in the United States, Europe and elsewhere are often uncertain, contradictory and in flux. Among other things, foreign privacy laws impose significant obligations on U.S. companies to protect the personal information of foreign citizens. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our data practices, which could have a material adverse effect on our business. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business.

Recent Sales of Unregistered Securities
On December 12, 2024, Salarius entered into a securities purchase agreement (the “ELOC Agreement”) with C/M Capital Master Fund, LP (the “Purchaser”), pursuant to which Salarius, subject to the restrictions and satisfaction of the conditions in the ELOC Agreement, has the right, but not the obligation, to sell to the Purchaser, and the Purchaser is obligated to purchase, up to the lesser of (i) $10 million of newly issued shares (the “Purchase Shares”) of Salarius’ common stock and (ii) the Exchange Cap (as defined in the ELOC Agreement). As consideration for the Purchaser’s execution and delivery of the ELOC Agreement, Salarius has agreed to issue to the Purchaser, simultaneously with the delivery of any and all Purchase Shares purchased under the ELOC Agreement, a number of shares of Salarius common stock equal to one percent (1%) of the number of Purchase Shares actually sold in each sale under the ELOC Agreement.
In the Purchase Agreement, the Purchaser represented to the Company, among other things, that it is an “accredited investor” (as such term is defined in Rule 501(a)(3) of Regulation D promulgated under the Securities
Act of 1933, as amended (the “Securities Act”)). The securities are being issued and sold by the Company to the Purchaser in reliance upon the exemptions from the registration requirements of the Securities Act afforded by Section 4(a)(2) of the Securities Act and Rule 506(b) of Regulation D promulgated thereunder. The securities may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
Between January 13, 2025 and March 7, 2025, Salarius issued and sold 283,933 Purchase Shares to the Purchaser pursuant to the ELOC Agreement at a weighted average exercise price of $2.61 for an aggregate purchase price of $740,500. These issuances and sales were made following written notice delivered by Salarius to Investor, directing Investor to purchase the Purchase Shares. Salarius also issued 2,839 shares of its common stock to the Purchaser as commitment shares pursuant to the terms of the ELOC Agreement.
Other than as described above or as previously disclosed on our Current Reports on Form 8-K or Quarterly Reports on Form 10-Q filed with the SEC, we did not issue any unregistered equity securities during the twelve months ended December 31, 2024.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Overview
This Management’s Discussion and Analysis provides material historical and prospective disclosures intended to enable investors and other users to assess our financial condition and results of operations. Statements that are not historical are forward-looking and involve risks and uncertainties discussed under the headings Special Note Regarding Forward-Looking Statements” and “Risk Factors” of this report. The following discussion of our results of operations and financial condition should be read in conjunction with our financial statements and the related notes thereto included elsewhere in this report. These risks could cause our actual results to differ materially from any future performance suggested below.
Introduction
Our Management's Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, is provided in addition to the accompanying consolidated financial statements and notes to assist readers in understanding our results of operations, financial condition, and cash flows.
Overview
Salarius is a clinical-stage biopharmaceutical company that has been focused on developing effective treatments for patients with cancer with high, unmet medical need. Specifically, Salarius has been concentrated on developing treatments for cancers caused by dysregulated gene expression (i.e., genes which are incorrectly turned on or off). Salarius has two classes of drugs that address gene dysregulation: targeted protein inhibitors and targeted protein degraders. Salarius’ technologies have the potential to work in both liquid and solid tumors. Salarius’ current pipeline consists of two small molecule drugs: (1) SP-3164, a targeted protein degrader, and (2) seclidemstat (“SP-2577”), a targeted protein inhibitor.
Recent Developments
Entry into Merger Agreement with Decoy Therapeutics, Inc. (“Decoy”)
On August 8, 2023, Salarius announced that it retained Canaccord Genuity, LLC to lead a comprehensive review of strategic alternatives focusing on maximizing stockholder value, including but not limited to, an acquisition, merger, reverse merger, divestiture of assets, licensing, or other strategic transactions involving the company. On January 10, 2025, Salarius entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Decoy
Therapeutics MergerSub I, Inc., a Delaware corporation and a wholly owned subsidiary of Salarius (“First Merger Sub”), Decoy Therapeutics MergerSub II, LLC, a Delaware limited liability company and wholly owned subsidiary of Salarius (“Second Merger Sub”), and Decoy. Pursuant to the Merger Agreement, Salarius will combine with Decoy (the “Merger”) by causing First Merger Sub to be merged with and into Decoy, with Decoy surviving the merger as a wholly owned subsidiary of Salarius (the “First Merger”). Immediately following the First Merger, Decoy will merge with and into Second Merger Sub, with Second Merger Sub being the surviving entity and continuing under the name “Decoy Therapeutics, LLC” as a wholly owned subsidiary of Salarius.
The Merger is structured as a stock-for-stock transaction pursuant to which all of Decoy’s outstanding equity interests will be exchanged based on an exchange ratio for consideration of a combination of (a) shares of Salarius’ common stock par value $0.0001 (the “Common Stock”) in an amount up to (i) 19.9% of Salarius’ total shares outstanding as of January 10, 2025 minus (ii) any shares of Salarius Common Stock issued in any private placement between January 10, 2025 and the effective time of the First Merger (the “First Effective Time”), and (b) shares of Series A Preferred Stock, which is a newly designated series of preferred stock (“Preferred Stock”) that is intended to have economic rights equivalent to the Common Stock, but with only limited voting rights, in addition to the assumption of outstanding and unexercised stock options to purchase shares of Common Stock from the Decoy Therapeutics Inc. 2020 Equity Incentive Plan. The number of shares of Common Stock to be issued at Merger Closing (as defined below) and the number of shares of Common stock underlying the Series A Preferred Stock to be issued at closing of the Merger (the “Merger Closing”) is based on an exchange ratio which assumes a base value of $28.0 million for Decoy and $4.6 million for Salarius, subject in each case to adjustment based on the balance sheet cash available to each of Salarius and Decoy at Merger Closing (excluding any proceeds raised the “Qualified Financing,” as defined below). Based on these relative values, before taking into account the dilutive effects of the Qualified Financing, Salarius’ legacy stockholders would retain approximately 14.1% of Salarius on an as-converted-to-common basis and, after giving effect to the exchange ratio and the conversion of the Series A Preferred Stock, Decoy stockholders would own approximately 85.9% of Salarius.
The rights of the Series A Preferred Stock will be set forth in a Certificate of Designation of Preferences, Rights and Limitations that Salarius will file with the Secretary of State of the State of Delaware (the “Certificate of Designation”). The Certificate of Designation provides that the preferred stock will be convertible into shares of Common Stock on a 1-for-1000 basis, subject to stockholder approval. The Merger was approved by Salarius’ board of directors and the board of directors of Decoy. In addition, following the consummation of the Merger, Salarius has agreed to call a special stockholder meeting to approve (i) the conversion of the preferred stock to be issued at Merger Closing into shares of Common Stock (the “Conversion Proposal”), (ii) a new equity incentive plan in form reasonably agreed to by the parties (the “Equity Plan Proposal”), and (iii) if necessary and advisable, a reverse stock split in a ratio to be approved by Salarius’ board of directors (the “Reverse Stock Split Proposal” and together with the Conversion Proposal and the Equity Plan Proposal, the “Company Stockholder Matters”).
The Merger Agreement contains customary representations and warranties by each of Salarius and Decoy, as well as covenants relating to operating each respective business in the ordinary course prior to Merger Closing. The Merger Closing is conditioned upon, among other things, minimum proceeds from future offerings of at least $6.0 million (collectively, the “Qualified Financing”) and the continued listing of Salarius Common Stock on Nasdaq. On January 17, 2025, Nasdaq notified Salarius that the proposed transaction with Decoy constitutes a business combination that will result in a “Change of Control” pursuant to Listing Rule 5110(a) and, accordingly, the post-transaction entity will be required to satisfy all of Nasdaq’s initial listing criteria and to complete Nasdaq’s initial listing process, including the payment of all applicable fees. Salarius intends to commence the process prior to seeking the Company’s stockholder approval for the issuance of 20% or more of the Company’s pre-transaction shares and must complete the process prior to the conversion of the preferred shares issued at the Merger Closing into shares of common stock of the Company.
In connection with the execution of the Merger Agreement, Salarius entered into stockholder support agreements (the “Salarius Support Agreements”) with certain of its officers and directors, who collectively own an aggregate of approximately 1.38% of the outstanding shares of the Common Stock. The Salarius Support Agreements provide that, among other things, each of the parties thereto has agreed to vote or cause to be voted all of the shares of Common Stock owned by such stockholder in favor of the Company Stockholder Matters at a special or annual meeting of Salarius’ stockholders to be held in connection therewith. In addition, Decoy officers and directors, in their capacities as stockholders of Decoy, entered into stockholder support agreements (the “Decoy Support Agreements”) with Decoy. The Decoy Support Agreements provide that, among other things, each of the parties thereto has agreed to vote or cause to be voted all of the shares of Common Stock owned by such stockholder in favor of the proposed Merger.
Concurrently and in connection with the execution of the Merger Agreement, certain Decoy officers and directors, and certain of Salarius’ directors and officers entered into lock-up agreements with Salarius and Decoy, pursuant to which each such stockholder will be subject to a 180-day lockup on the sale or transfer of shares of Common Stock held by each such stockholder at the Merger Closing, including those shares received by Decoy stockholders in the Merger.
Although we have entered into the Merger Agreement and intend to consummate the Merger, there is no assurance that we will be able to successfully consummate the Merger on a timely basis, or at all. If, for any reason, the Merger does not close, our board of directors may elect to, among other things, attempt to complete another strategic transaction like the Merger, attempt to sell or otherwise dispose of our various assets, resume our research and development activities and continue to operate our business or dissolve and liquidate our assets. If we decide to dissolve and liquidate our assets, we would be required to pay all of our debts and contractual obligations, and to set aside certain reserves for potential future claims, and there can be no assurances as to the amount or timing of available cash left, if any, to distribute to stockholders after paying our debts and other obligations and setting aside funds for reserves. If we were to continue our business, we would need to raise a substantial amount of cash to fund ongoing operations and future development activities for our existing product candidates and any new product candidates that we acquire.
Warrant Cancellation Agreement
On January 10, 2025, Salarius entered into a Warrant Cancellation Agreement (the “Warrant Cancellation Agreement”) with an accredited investor. Salarius previously issued to the investor a Series A-1 Common Stock Purchase Warrant to purchase 454,546 shares of its common stock pursuant to the offering described in Salarius’ Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on May 16, 2023 (the “Warrant”). Pursuant to the Warrant Cancellation Agreement, on January 10, 2025, Salarius paid the investor an aggregate amount in cash of $350,000 in exchange for the surrender and cancellation of the Warrant.
Securities ELOC Agreement
On December 12, 2024, Salarius entered into a securities purchase agreement (the “ELOC Agreement”) with C/M Capital Master Fund, LP (the “Purchaser”), pursuant to which Salarius, subject to the restrictions and satisfaction of the conditions in the ELOC Agreement, has the right, but not the obligation, to sell to the Purchaser, and the Purchaser is obligated to purchase, up to the lesser of (i) $10 million of newly issued shares (the “Purchase Shares”) of Salarius’ common stock and (ii) the Exchange Cap (as defined in the ELOC Agreement). As consideration for the Purchaser’s execution and delivery of the ELOC Agreement, Salarius has agreed to issue to the Purchaser, simultaneously with the delivery of any and all Purchase Shares purchased under the ELOC Agreement, a number of shares of Salarius common stock equal to one percent (1%) of the number of Purchase Shares actually sold in each sale under the ELOC Agreement.
Between January 13, 2025 and March 7, 2025, Salarius issued and sold 283,933 Purchase Shares to the Purchaser pursuant to the ELOC Agreement at a weighted average exercise price of $2.61 for an aggregate purchase price of $740,500. These issuances and sales were made following written notice delivered by Salarius to Investor, directing Investor to purchase the Purchase Shares. Salarius also issued 2,839 shares of its common stock to the Purchaser as commitment shares pursuant to the terms of the ELOC Agreement.
We have no products approved for commercial sale and have not generated any revenue from product sales. We have never been profitable and have incurred operating losses in each year since inception. We had an accumulated deficit of $81.9 million as of December 31, 2024. Substantially all of our operating losses resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations.
The lack of revenue from product sales to date and recurring losses from operations since our inception raise substantial doubt as to our ability to continue as a going concern. We will continue to require substantial additional capital to continue our operation and clinical development activities and may need such additional capital sooner than 12 months. As of December 31, 2024, we had cash and cash equivalents of $2.4 million. Accordingly, we will need to raise substantial additional capital to continue to fund our operations beyond the later part of the second quarter of 2025. The amount and timing of our future funding requirements will depend on many factors, including the result of our strategic alternatives process, our ability to raise additional capital on commercially reasonable terms, the pace and results of clinical development activities, and market conditions. Failure to raise capital as and
when needed, on favorable terms or at all, would have a negative impact on our financial condition and our ability to continue our operations.
Results of Operations
The following table sets forth the consolidated results of our operations for the year ended December 31, 2024 compared to the year ended December 31, 2023.
Year ended December 31 Change
2024 2023
Research and development expenses 770,027 7,173,747 (6,403,720)
General and administrative expenses 4,964,289 5,721,197 (756,908)
Interest income (expense), net 158,539 352,251 -193,712
Net loss $ (5,575,777) $ (12,542,693) $ 6,966,916
Research and Development Expenses
Research and development expenses were $0.8 million during the year ended December 31, 2024 compared to $7.2 million during the year ended December 31, 2023. This decrease of $6.4 million principally resulted from the cost savings plan implemented during the third quarter of 2023 and lower spending on SP-2577. Lower research and development expenses will continue in 2025 as we have curtailed our sponsored clinical trials and intend to rely on clinical trial data from the investigator initiated clinical trial conducted by MD Anderson Cancer Center before assessing next steps in our clinical development plans.

candidates and by categories: 2024 2023 2024 2023
Outsourced research and development costs $ 69,753 $ 2,662,072 $ 345,228 $ 1,342,878
Employee-related costs 263,302 1,568,402
Manufacturing and laboratory costs 275,827 1,203,934 79,219 133,159
Purchased in process research and development costs - -
Total research and development costs $ 345,580 $ 4,129,308 $ 424,447 $ 3,044,439
General and Administrative Expense
General and administrative expenses were $5.0 million for the year ended December 31, 2024 compared to $5.7 million for the year ended December 31, 2023, the decrease is mainly driven by lower personnel costs, public company expenses and D&O insurance cost, offsetting by increased legal expense and severance payments.
Liquidity and Capital Resources
Current and Future Financing Needs
Since inception, we have incurred operating losses and we anticipate that we will continue to incur losses for the foreseeable future. We have not generated any cash inflows from product sales. We do not know when, or if, we will generate any revenue from product sales. We do not expect to generate any revenue from product sales unless and until we obtain regulatory approval for and commercializes any of our product candidates, all of which are in early stages of development. We have curtailed expenses and plan to use our two remaining full time employees and consultants to continue our operations.
During the twelve months ended December 31, 2024, we received $0.1 million of cash from CPRIT. As of December 31, 2024, we had $1.5 million of working capital and our cash and cash equivalents totaled $2.4 million, which were held in bank and money market accounts. Our cash and cash equivalents balance decreased during the year ended December 31, 2024, primarily due to the cash used in operating activities, partially offset by capital
received from financing activities. Under current reduced operating conditions, we believe that our cash and cash equivalents on hand as of December 31, 2024 is sufficient to fund our anticipated operations into the later part of the second quarter of 2025. If for any reason the Merger does not close, we would need to raise additional capital to continue to fund the further development of product candidates and our operations. If we are unable to maintain sufficient financial resources, our business, financial condition and results of operations will be materially and adversely affected. Additionally, equity or debt financings may have a dilutive effect on the holdings of our existing stockholders. We have curtailed expenses and plan to use our two remaining full time employees and consultants to continue our operations. As a result, if we are unable to complete the Merger, we will likely need to conduct a wind down of our operations.

Net cash (used in) provided by:
Operating activities $ (4,525,337) $ (12,846,137)
Financing activities 1,059,955 6,639,612
Net increase (decrease) in cash and cash equivalents $ (3,465,382) $ (6,206,525)

Net cash provided by financing activities $ 1,059,955 $ 6,639,612
Operating Activities
Net cash used in operating activities was $4.5 million in the current period, a decrease of approximately $8.3 million from the same period a year ago. The decrease is primarily due to significantly reduced operating expenses during current year compared to last year.
Critical Accounting Policies and Significant Judgments and Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the consolidated balance sheet and the reported amounts of expenses during the reporting period. In accordance with GAAP, we base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances at the time such estimates are made. Actual results may differ materially from our estimates and judgments under different assumptions or conditions. We periodically review our estimates in light of changes in circumstances, facts and experience. The effects of material revisions in estimates are reflected in our consolidated financial statements prospectively from the date of the change in estimate.
Our significant accounting policies are described in Note 2 to our audited consolidated financial statements for the year ended December 31, 2024 in this Annual Report on Form 10-K. We believe that our accounting policy relating to research and development expenses is the most critical to understanding and evaluating our reported financial results. We have identified this policy as critical because it is important to the presentation of our financial condition and results of operations and requires us to make judgments and estimates on matters that are inherently uncertain and may change in future periods. For more information regarding these policies, you should refer to Note 2 of our audited consolidated financial statements included in this Annual Report on Form 10-K.
Off-Balance Sheet Arrangements
We have not entered into any off-balance sheet arrangements and does not have any holdings in variable interest entities.
Application of New Accounting Standards
See Note 2 - Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements for a description of recently issued accounting pronouncements, including the expected dates of adoption and estimated effects on our results of operations, financial positions and cash flows.

To the Shareholders and the Board of Directors of Salarius Pharmaceuticals, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Salarius Pharmaceuticals, Inc. (the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations, stockholders’ equity (deficit) and cash flows for each of the two years in the period ended December 31, 2024, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.
The Company’s Ability to Continue as a Going Concern
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has a lack of revenue from product sales and has suffered recurring losses from operations since its inception and has stated that substantial doubt exists about the Company's ability to continue as a going concern. Management's evaluation of the events and conditions and management’s plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates.
Clinical Trial Accruals
Description of the Matter
The Company’s Accrued expenses and other current liabilities was $352,419 at December 31, 2024, and Research and development was $770,027 for the year then ended. As noted in the consolidated financial statements, research and development costs consist of expenses incurred in performing research and development activities, including pre-clinical studies and clinical trials, and these costs consist of salaries and personnel-related costs, consulting fees, fees paid for contract research services, the costs of laboratory equipment and facilities, license fees and other external costs. The Company’s preclinical and clinical trials are performed by third party contract research organizations (CROs) and/or clinical investigators, and clinical supplies are manufactured by contract manufacturing organizations (CMOs). The Company accrues expenses based upon its assessment of the status of each clinical trial and the work completed and upon information obtained from the CROs and CMOs.
Auditing the Company’s accounting for accrued third-party clinical trial research and development expenses is especially challenging because of the judgment applied by management to determine the progress or stage of completion of the activities under the Company’s research and development agreements and the cost and extent of work performed during the reporting period for services not yet billed by contracted third-party vendors.
How We Addressed the Matter in Our Audit
Our audit procedures included, among others, inspecting the terms and conditions of the Company’s contracts with third parties, obtaining external confirmation of key inputs to the accrual calculation on a sample basis, testing the accuracy and completeness of the underlying inputs used in management’s analysis to determine costs incurred, and clerically tested the accrual calculation. We also reviewed invoices received and subsequent disbursements made after the balance sheet date to evaluate the completeness of the research and development expenses recognized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1. ORGANIZATION AND OPERATIONS
Nature of Business
Salarius Pharmaceuticals, Inc. (“Salarius” or the “Company”), together with its subsidiaries, Salarius Pharmaceuticals, LLC, Flex Innovation Group LLC, and TK Pharma, Inc., is a clinical-stage biopharmaceutical company that has been focused on developing effective treatments for patients with cancer with high, unmet medical need. Specifically, Salarius has been concentrated on developing treatments for cancers caused by dysregulated gene expression (i.e., genes which are incorrectly turned on or off). Salarius has two classes of drugs that address gene dysregulation: targeted protein inhibitors and targeted protein degraders. Salarius’ technologies have the potential to work in both liquid and solid tumors. Salarius’ current pipeline consists of two small molecule drugs: (1) SP-3164, a targeted protein degrader, and (2) seclidemstat (“SP-2577”), a targeted protein inhibitor. The Company is located in Houston, Texas. On August 8, 2023, the Company announced that it retained Canaccord Genuity, LLC to lead a comprehensive review of strategic alternatives focusing on maximizing stockholder value, including but not limited to, an acquisition, merger, reverse merger, divestiture of assets, licensing, or other strategic transactions involving the Company. In connection with the evaluation of strategic alternatives and in order to extend Company resources, the Company implemented multiple cost-savings plans to extend the Company’s expected cash runway into the later part of the second quarter of 2025.
On January 10, 2025, Salarius entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Decoy Therapeutics MergerSub I, Inc., a Delaware corporation and a wholly owned subsidiary of Salarius (“First Merger Sub”), Decoy Therapeutics MergerSub II, LLC, a Delaware limited liability company and wholly owned subsidiary of Salarius (“Second Merger Sub”), and Decoy. Pursuant to the Merger Agreement, and subject to the satisfaction and waiver of certain conditions set forth in the Merger Agreement, Salarius will combine with Decoy (the “Merger”) by causing First Merger Sub to be merged with and into Decoy, with Decoy surviving the merger as a wholly owned subsidiary of Salarius (the “First Merger”). Immediately following the First Merger, Decoy will merge with and into Second Merger Sub, with Second Merger Sub being the surviving entity and continuing under the name “Decoy Therapeutics, LLC” as a wholly owned subsidiary of Salarius. See Note 11, Subsequent Events, for further information.
Going Concern
Salarius has no products approved for commercial sale, has not generated any revenue from product sales to date and has suffered recurring losses from operations since its inception. The lack of revenue from product sales to date and recurring losses from operations since its inception raise substantial doubt as to the Company's ability to continue as a going concern. The accompanying financial statements are prepared using accounting principles generally accepted in the United States applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities should the Company be unable to continue as a going concern. Based on Salarius’ expected cash requirements, Salarius believes that there is substantial doubt that its existing cash and cash equivalents, will be sufficient to fund its operations through one year from the financial statements' issuance date. The Company may attempt to obtain additional capital through the sale of equity securities in one or more offerings or through issuances of debt instruments, and may also consider new collaborations or selectively partnering its technology. However, the Company cannot provide any assurance that it will be successful in accomplishing any of its plans.
If the Company is unable to consummate the Merger or obtain additional capital in the very near term, it will be forced to cease operations, liquidate its assets and pursue the winding down and dissolution of the Company.
Reverse Stock Splits
On June 14, 2024, the Company filed a Certificate of Amendment to the Company’s restated certificate of incorporation, as amended, with the Secretary of State of the State of Delaware to effect a 1-for-8 reverse stock split of the Company’s issued and outstanding shares of common stock, par value $0.0001 per share (the “2024 Reverse Stock Split”) which became effective as of June 14, 2024.
On October 14, 2022, the Company filed a Certificate of Amendment to the Company’s restated certificate of incorporation with the Secretary of State of the State of Delaware to effect a 1-for-25 reverse stock split of the Company’s issued and outstanding shares of common stock, par value $0.0001 per share (the “2022 Reverse Stock Split” and together with the 2024 Reverse Stock Split, the “Reverse Stock Splits”) which became effective as of October 14, 2022.
All historical share and per share amounts reflected throughout this report have been adjusted to reflect the Reverse Stock Splits.
NOTE 2. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standard Codification ("ASC") and Accounting Standards Update ("ASU") of the Financial Accounting Standards Board ("FASB").
The Company considered its going concern disclosure requirements in accordance with ASC 205-40-50.The Company has performed an analysis and concluded substantial doubt exists with respect to the Company being able to continue as a going concern through one year from the date of issuance of the consolidated financial statements for the year ended December 31, 2024.
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America as defined by the FASB ASC requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates.
Cash and Cash Equivalents
Salarius considers all highly-liquid investments with original maturities of three months or less to be cash equivalents.
Impairment of Long-Lived Assets
Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying value may not be recoverable. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. There were no impairment charges related to long-lived assets during the twelve months ended December 31, 2024 and 2023.
Financial Instruments and Credit Risks
Financial instruments that potentially subject the Company to credit risk include cash and cash equivalents and restricted cash. Cash is deposited in demand accounts in federally insured domestic institutions to minimize risk. Insurance is provided through the Federal Deposit Insurance Corporation (“FDIC”). Although the balances in these accounts exceed the federally insured limit from time to time, the Company has not incurred losses related to these deposits.
Warrants
The Company determines whether warrants should be classified as a liability or equity. For warrants classified as liabilities, the Company estimates the fair value of the warrants at each reporting period using Level 3 inputs with changes in fair value recorded in the Consolidated Statement of Operations within change in fair value of warrant liability. The estimates in valuation models are based, in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the risk-free interest rate and the fair value of the common stock underlying the warrants, and could differ materially in the future. The Company will continue to adjust the fair value of the warrant liability at the end of each reporting period for changes in fair value from the prior period until the earlier of the exercise or expiration of the applicable warrant. For warrants classified as equity contracts, the Company allocates the transaction proceeds to the warrants and any other free-standing instruments issued in the transaction based on an allowable allocation method.
Clinical Trial Accruals
The Company’s preclinical and clinical trials are performed by third party contract research organizations (CROs) and/or clinical investigators, and clinical supplies are manufactured by contract manufacturing organizations (CMOs). Invoicing from these third parties may be monthly based upon services performed or based upon milestones achieved. The Company accrues these expenses based upon its assessment of the status of each clinical trial and the work completed, and upon information obtained from the CROs and CMOs. The Company’s estimates are dependent upon the timeliness and accuracy of data provided by the CROs and CMOs regarding the status and cost of the studies, and may not match the actual services performed by the organizations. This could result in adjustments to the Company’s research and development expenses in future periods. To date the Company has had no significant adjustments.
Grants Receivable and Revenue Recognition
Salarius’ source of revenue has been from a grant received from CPRIT. Grant revenue is recognized when qualifying costs are incurred and there is reasonable assurance that conditions of the grant have been met. Cash received from grants in advance of incurring qualifying costs is recorded as deferred revenue and recognized as revenue when qualifying costs are incurred. The Company records revenue and a corresponding grants receivable when qualifying costs are incurred before the grants are received. The Company's CPRIT grant expired during 2023 and no additional amounts are expected to be recognized or received.
Research and Development Costs
Research and development costs consist of expenses incurred in performing research and development activities, including pre-clinical studies and clinical trials. Research and development costs include salaries and personnel-related costs, consulting fees, fees paid for contract research services, the costs of laboratory equipment and facilities, license fees and other external costs. Research and development costs are expensed when incurred.
Equity-Based Compensation
Salarius measures equity-based compensation based on the grant date fair value of the awards and recognizes the associated expense in the financial statements over the requisite service period of the award, which is generally the vesting period.
The Company uses the Black-Scholes option valuation model to estimate the fair value of the stock-based compensation and incentive units. Assumptions utilized in these models include expected volatility calculated based on implied volatility from traded stocks of peer companies, dividend yield and risk-free interest rate. Additionally, forfeitures are accounted for in compensation cost as they occur.
Segment Information
Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision maker, or CODM, in making decisions on how to allocate resources and assess performance. The CODM is the Company’s Chief Executive Officer. The Company views its operations as and manages its business in one operating segment, focused on the discovery and development therapeutics for patients with cancer with high, unmet medical need. The Company operates in one geographic segment. Segment information is further described in Note 10, “Segment Reporting”.
Loss Per Share
Basic net loss per share is calculated by dividing the net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Since the Company was in a loss position for all periods presented, diluted net loss per share is the same as basic net loss per share for all periods, as the inclusion of all potential common shares outstanding is anti-dilutive.
The number of anti-dilutive shares, consisting of common shares underlying (i) common stock options, (ii) stock purchase warrants, (iii) unvested restricted stock and (iv) rights entitling holders to receive warrants to purchase the Company's common shares, which have been excluded from the computation of diluted loss per share, was 592,524 and 1,366,892 shares as of December 31, 2024 and 2023, respectively.
Income Taxes
Income taxes are recorded in accordance with FASB ASC Topic 740, Income Taxes ("ASC 740"), which provides for deferred taxes using an asset and liability approach. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and the tax reporting basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. The Company provides a valuation allowance against net deferred tax assets unless, based upon the available evidence, it is more likely than not that the deferred tax assets will be realized. The Company has evaluated available evidence and concluded that the Company may not realize the benefit of its deferred tax assets; therefore, a valuation allowance has been established for the full amount of the deferred tax assets.
The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of December 31, 2024 and 2023, the Company did not have any significant uncertain tax positions and no interest or penalties have been charged. The Company's practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company is subject to routine audits by taxing jurisdictions.
Pronouncements Not Yet Adopted
In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid by jurisdiction. The ASU is effective for public business entities for annual periods beginning after December 15, 2024, with early adoption permitted. The Company will adopt ASU No. 2023-09 prospectively in its fiscal year 2025.
In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU No. 2024-03”), which requires disaggregated disclosure of certain costs and expenses, including purchases of inventory, employee compensation, depreciation, amortization and depletion, within relevant income statement captions. ASU No. 2024-03 is effective for annual periods beginning after December 15, 2026 and for interim periods beginning after December 15, 2027 on a retrospective or prospective basis, with early adoption permitted. The Company is evaluating the effect that ASU No. 2024-03 will have on its financial statement disclosures.
Recently Adopted Accounting Standard
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting - Improvements to Reportable Segment Disclosures,” which requires disclosure of incremental segment information on an annual and interim basis and also requires companies with a single reportable segment to provide all disclosures required by this ASU and all existing segment disclosures in Accounting Standard Codification (“ASC”) 280, “Segment Reporting.” The requirements of the ASU are effective for fiscal years beginning after December 15, 2023 and interim periods beginning after December 15, 2024. The adoption of the standard did not have a material impact on the Company's consolidated financial statements.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement of all expected credit losses for financial assets including trade receivables held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Subsequent to the issuance of ASU 2016-13, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. This ASU does not change the core principle of the guidance in ASU 2016-13, instead these amendments are intended to clarify and improve operability of certain topics included within the credit losses guidance. The FASB also subsequently issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Derivatives and Hedging (Topic 815), and Financial Instruments (Topic 825), which did not change the core principle of the guidance in ASU 2016-13, but clarified that expected recoveries of amounts previously written off and expected to be written off should be included in the valuation account and should not exceed amounts previously written off and expected to be written off. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019 for public business entities, excluding smaller reporting companies. Early adoption is permitted. As a smaller reporting company, the guidance was effective for the Company on January 1, 2023. The adoption of this standard did not have a material impact to this Company's consolidated financial statements.
NOTE 3. GRANTS RECEIVABLE
Grants receivable represents qualifying costs incurred where there is reasonable assurance that conditions of the grant have been met but the corresponding funds have not been received as of the reporting date. Grants receivable balances were $0 as of December 31, 2024 and December 31, 2023, respectively. The Company received $1.5 million from the Cancer Prevention and Research Institute of Texas on February 15, 2023.
NOTE 4. PREPAID EXPENSES AND OTHER CURRENT ASSETS
Prepaid expenses and other current assets at December 31, 2024 and 2023 consisted of the following:
December 31,
2024 2023
Prepaid insurance 287,785 468,495
Deferred offering cost 221,580 -
Other prepaid and current assets 43,669 151,268
Total prepaid expenses and other current assets $ 553,034 $ 619,763
Prepaid insurance is mainly comprised of prepaid directors' and officers' insurance. In July 2024 and 2023, the Company financed its directors and officers' insurance premium with a short term note the principal amount of which is approximately $0.4 million and $0.6 million bearing interest at a rate of 9.74% and 7.87%, respectively. The note payable balance, which was included within Current Liabilities on the Consolidated Balance Sheet was $0.2 million and $0.3 million as of December 31, 2024 and 2023 .
NOTE 5. COMMITMENTS AND CONTINGENCIES
Cancer Prevention and Research Institute of Texas
In June 2016, the Company entered into a Cancer Research Grant Contract with CPRIT. Pursuant to the contract, CPRIT awarded the Company a grant up to $18.7 million, further modified to $16.1 million to fund development of LSD 1 inhibitor. The grant expired during 2023.
The Company will retain ownership over any intellectual property developed under the contract ("Project Result"). With respect to non-commercial use of any Project Result, the Company agreed to grant to CPRIT a nonexclusive, irrevocable, royalty-free, perpetual, worldwide license with right to sublicense any necessary additional intellectual property rights to exploit all Project Results by CPRIT, other governmental entities and agencies of the State of Texas, and private or independent institutions of higher education located in Texas, for education, research and other non-commercial purposes.
The Company is obligated to make revenue-sharing payments to CPRIT with respect to net sales of any product covered by the contract, up to a maximum repayment of certain percentage of the aggregate amount paid to the Company by CPRIT under the CPRIT contract. The payments are determined as a percentage of net sales, which may be reduced if the Company is required to obtain a license from a third party to sell any such product. In addition, upon meeting the foregoing limitation on revenue-sharing payments, the Company agreed to make continued revenue-sharing payments to CPRIT of less than 1% of net sales.
License Agreement with the University of Utah Research Foundation
In 2011, the Company entered into a license agreement with the University of Utah, under which, the Company acquired license to LSD 1. In exchange for the license, the Company issued 2% equity ownership in the Company based on a fully diluted basis at the effective date of the agreement and subject to certain adjustments specified in the agreement, granted revenue sharing rights on any resulting products or processes to commence on first commercial sale, and milestone payments based upon regulatory approval of any resulting product or process as well as on the second anniversary of first commercial sale.
Lease Agreement
The Company presently leases office space under operating lease agreements on a month to month basis.
6. FAIR VALUE OF FINANCIAL INSTRUMENTS
Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. A fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last is considered unobservable, are used to measure fair value:
Level 1-Unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2-Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3-Significant unobservable inputs including Salarius’ own assumptions in determining fair value.
The Company believes the recorded values of its financial instruments, including cash and cash equivalents, accounts payable and note payable approximate their fair values due to the short-term nature of these instruments.
7. STOCKHOLDERS' EQUITY
Common Stock Issuances
On February 5, 2021, the Company entered into an At the Market Offering Agreement ("ATM") with Ladenburg Thalmann & Co. Inc. Under this agreement the Company is able to issue and sell, from time to time, shares of its common stock. On February 5, 2021 and July 2, 2021, the Company filed prospectus supplements with the SEC to register the offering and sale of Common Stock having an aggregate offering price of up to $6.3 million and $25.0 million, respectively. During the twelve months ended December 31, 2024 and 2023, the Company sold 608,949 and 87,034 shares of common stock under the At the Market Offering Agreement with gross proceeds of $1.7 million and $1.7 million, respectively.
On May 11, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an accredited investor (the “Investor”), pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Offering”) (i) 41,250 shares (the “Shares”) of the Company’s common stock, par $0.0001 per share (the “Common Stock”), (ii) pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 413,296 shares of Common Stock, (iii) Series A-1 warrants (the “Series A-1 Warrants”) to purchase up to 454,546 shares of Common Stock and (iv) Series A-2 warrants (the “Series A-2 Warrants”) and together with the Series A-1 Warrants, the “Common Stock Warrants,” and together with the Pre-Funded Warrants, the “Warrants”) to purchase up to 454,546 shares of Common Stock, at a purchase price of (a) $13.2 per Share and accompanying Common Stock Warrants and (b) $13.1992 per Pre-Funded Warrant and accompanying Common Stock Warrants. The aggregate gross proceeds from the Offering were approximately $6 million, exclusive of placement agent fees and expenses and other offering expenses. The Offering closed on May 16, 2023. All of the Series A-2 Warrants had expired as of December 31, 2024.
All of Pre-Funded Warrants were fully exercised as of December 31, 2024.
On December 12, 2024, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with C/M Capital Master Fund, LP (the “Purchaser”), pursuant to which the Company, subject to the restrictions and satisfaction of the conditions in the Purchase Agreement, has the right, but not the obligation, to sell to the Purchaser, and the Purchaser is obligated to purchase, up to the lesser of (i) $10 million of newly issued shares (the “Purchase Shares”) of the Company’s common stock, $0.0001 par value per share (the “Common Stock”) and (ii) a specified cap dictated by the rules of the Nasdaq Stock Market. As consideration for the Purchaser’s execution and delivery of the Purchase Agreement, the Company has agreed to issue to the Purchaser, simultaneously with the delivery of any and all Purchase Shares purchased under the Purchase Agreement, a number of shares of Common Stock equal to one percent (1%) of the number of Purchase Shares actually sold in each sale under the Purchase Agreement (the “Commitment Shares” and, together with the Purchase Shares, the “Securities”).
Warrants Exercised for Cash
The Company has five-year warrants outstanding that were issued in February 2020 and subsequently modified in December 2020 in connection with the issuance of additional inducement warrants. The warrants are exercisable at a price per share of $230.00. The inducement warrants expire on June 11, 2026, and are exercisable at a price per share of $236.40. The Company has 35,023 warrants outstanding that were issued in April 2022, with an exercise price of $67.98 per share. The warrants were exercisable six months following the issuance date and will expire five and one-half years from the issuance date. During the twelve months ended December 31, 2024 and 2023, no warrants were exercised.
In May 2023, the Company issued Series A-1 Warrants that are exercisable for a period of five and one-half (5.5) years from the issuance date at an exercise price of $11.2 per share. Series A-2 Warrants are exercisable for a period of eighteen (18) months from the issuance date at an exercise price of $11.2 per share. Each Pre-Funded Warrant was sold in lieu of shares of Common Stock, are exercisable immediately upon issuance, have an exercise price of $0.0001 per share and expire when exercised in full. During the twelve months ended December 31, 2024 and 2023, no Series A-1 or A-2 warrants were exercised. All of the Series A-2 Warrants had expired as of December 31, 2024.
In connection with the above mentioned Offering, the Company issued warrants to its exclusive placement agency H.C Wainwright & Co., LLC to purchase up to 31,818 shares of common stock at an exercise price per share of $16.5 and a term of five and one-half (5.5) years. During the twelve months ended December 31, 2024 and 2023, no warrants were exercised.
As of December 31, 2024 and 2023, approximately 560,839 and 1,355,598 warrants remained outstanding, respectively.
The terms of the outstanding warrants require the Company, upon the consummation of any fundamental transaction to, among other obligations, cause any successor entity resulting from the fundamental transaction to assume the Company's obligations under the warrants and the associated transaction documents. In addition, holders of warrants are entitled to participate in any fundamental transaction on an as-converted or as-exercised basis, which could result in the holders of the Company's common stock receiving a lesser portion of the consideration from a fundamental transaction. The terms of the warrants could also impede the Company's ability to enter into certain transactions or obtain additional financing in the future.
8. EQUITY-BASED COMPENSATION
Equity Incentive Plans
The Company has granted options to employees, directors, and consultants under the 2015 Equity Incentive Plan (the "2015 Plan"). The 2015 Plan provides for the grant of incentive stock options ("ISOs"), nonstatutory stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance-based stock awards and other stock-based awards. Additionally, the 2015 Plan provides for the grant of performance-based cash awards. ISOs may be granted only to the Company's employees. All other awards may be granted to the Company's employees, including officers, and to non-employee directors and consultants. As of December 31, 2024 and 2023, there were 9,844 and 10,542 shares, respectively, remaining available for the grant of stock option under the 2015 Plan. The 2015 Plan expired in accordance with its terms in January 2025.
During the twelve months ended December 31, 2024 and 2023, the Company awarded 21,125 and 0, respectively, stock options to its employees and directors, pursuant to the plan described above. Stock options generally vest over one to four years and have a contractual term of ten years. Stock options are valued using the Black-Scholes option pricing model and compensation cost is recognized based on the resulting value over the service period. Expected volatilities utilized in the model are based on implied volatilities from traded stocks of peer companies. Similarly, the dividend yield is based on historical experience and the estimate of future dividend yields. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect at the time of grant. The expected term of the options is based on the average period the stock options are expected to remain outstanding. The fair value of the option grants of $0.1 million has been estimated with the following assumptions for the year ended December 31, 2024:
Risk-free interest rate 4.25%-4.61%
Volatility 106.07% - 123.31%
Expected life (years) 5 -6 years
Expected dividend yield 0.00 %
The following table summarizes stock option activity for employees and non-employees for the twelve months ended December 31, 2024 and 2023:

As of December 31, 2024 and 2023, there was approximately $0.1 million and $0.3 million of total unrecognized compensation cost, respectively, related to unvested stock options. Total unrecognized compensation cost will be adjusted for future changes in employee and non-employee forfeitures, if any. The Company expects to recognize that cost over a remaining weighted-average period of 0.51 years.
9. INCOME TAX
The Company has no current or deferred tax expense due to its current year loss and its overall net operating loss position. A reconciliation of the federal statutory tax rate and the effective tax rates for the year ended December 31, 2024 and 2023 is as follows:
December 31
2024 2023
Federal Tax at Statutory Rate 21.00% 21.00%
Permanent (0.83)% (0.89)%
Change in Valuation Allowance (21.51)% (22.77)%
True Ups -% -%
R&D Credit 1.34% 2.66%
Effective Tax Rate -% -%
The tax effects of temporary differences that give rise to significant portions of the deferred tax assets were as follows:
December 31
2024 2023
Capitalized R&D Expenses $ 4,565,699 $ 5,610,221
Other Deferred Items 43,982 44,193
Stock Compensation 437,328 455,192
Net Operating Loss - US 8,349,314 6,161,916
R&D Credits 3,701,895 3,627,377
Net deferred tax assets 17,098,218 15,898,899
Valuation Allowance
(17,098,218) (15,898,899)
Net deferred tax assets (liabilities) $ - $ -
The valuation allowance recorded by the Company as of December 31, 2024 and December 31, 2023 resulted from the uncertainties of the future utilization of deferred tax assets relating from NOL carry forwards for federal and state income tax purposes. Realization of the NOL carry forwards is contingent on future taxable earnings. The deferred tax asset was reviewed for expected utilization using a “more likely than not” approach by assessing the available positive and negative evidence surrounding its recoverability. Accordingly, a full valuation allowance continues to be recorded against the Company’s deferred tax asset, as it was determined based upon past and projected future losses that it was “more likely than not” that the Company’s deferred tax assets would not be realized. In future years, if the deferred tax assets are determined by management to be “more likely than not” to be realized, the recognized tax benefits relating to the reversal of the valuation allowance will be recorded. The Company will continue to assess and evaluate strategies that will enable the deferred tax asset, or portion thereof, to be utilized, and will reduce the valuation allowance appropriately as such time when it is determined that the “more likely than not” criteria is satisfied.
The federal net operating loss carryforwards of $39.8 million have an indefinite life, but the R&D credits of $3.5 million begin to expire in 2039. Due to the change in ownership provisions of the Internal Revenue Code, the availability of the Company’s net operating loss carry forwards could be subject to annual limitations against taxable income in future periods, which could substantially limit the eventual utilization of such carry forwards. The Company has not analyzed the historical or potential impact of its equity financings on beneficial ownership and therefore no determination has been made whether the net operating loss carry forward is subject to any Internal Revenue Code Section 382 limitation. To the extent there is a limitation, there could be a reduction in the deferred tax asset with an offsetting reduction in the valuation allowance.
Tax positions taken or expected to be taken in the course of preparing the Company’s tax returns are required to be evaluated to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet a more-likely-than-not threshold, as well as accrued interest and penalties, if any, would be recorded as an interest and penalties expense in the current year. There were no uncertain tax positions that require accrual or disclosure to the financial statements as of December 31, 2024.
10. SEGMENT REPORTING
The Company has been concentrated on developing treatments for cancers caused by dysregulated gene expression. The current pipeline consists of two small molecule drugs: (1) SP-3164, a targeted protein degrader, and (2) seclidemstat (“SP-2577”), a targeted protein inhibitor. The Company does not have any revenue generating products.
For the year ended December 31, 2024 and December 31, 2023, the Company identified one operating and reportable segment relating to its operations. The Company defines its operating segment based on internally reported financial information that is regularly reviewed by the Chief Operating Decision Maker (the CODM), its Chief Executive Officer. The CODM reviews the segment’s loss based on net loss reported on the consolidated statement of operations.
The Company’s CODM views specific categories within research and development expenses and general and administrative expenses as significant given the direct correlation between cash burn as a pre-revenue company. The table below is a summary of the segment loss, including significant segment expenses:
Year Ended December 31
2024 2023
Expenses:
Research and development:
SP-3164 $ 345,580 $ 4,129,308
SP-2577 424,447 3,044,439
General and administrative:

11. SUBSEQUENT EVENTS
On January 10, 2025, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Decoy Therapeutics MergerSub I, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“First Merger Sub”), Decoy Therapeutics MergerSub II, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“Second Merger Sub”), and Decoy. Pursuant to the Merger Agreement, the Company will combine with Decoy (the “Merger”) by causing First Merger Sub to be merged with and into Decoy, with Decoy surviving the merger as a wholly owned subsidiary of the Company (the “First Merger”). Immediately following the First Merger, Decoy will merge with and into Second Merger Sub, with Second Merger Sub being the surviving entity and continuing under the name “Decoy Therapeutics, LLC” as a wholly-owned subsidiary of the Company.
The Merger is structured as a stock-for-stock transaction pursuant to which all of Decoy’s outstanding equity interests will be exchanged based on an exchange ratio for consideration of a combination of (a) shares of the Company’s common stock par value $0.0001 (the “Common Stock”) in an amount up to (i) 19.9% of the Company’s
total shares outstanding as of January 10, 2025 minus (ii) any shares of Salarius' Common Stock issued in any private placement between January 10, 2025 and the effective time of the First Merger (the "First Effective Time"), and (b) shares of Series A Preferred Stock, which is a newly designated series of preferred stock (“Preferred Stock”) that is intended to have economic rights equivalent to the Common Stock, but with only limited voting rights, in addition to the assumption of outstanding and unexercised stock options to purchase shares of Common Stock from the Decoy Therapeutics Inc. 2020 Equity Incentive Plan. The number of shares of common stock to be issued at the Closing and the number of shares of common stock underlying the Series A Preferred Stock to be issued at Closing is based on an exchange ratio which assumes a base value of $28.0 million for Decoy and $4.6 million for Salarius, subject in each case to adjustment based on the balance sheet cash available to each Salarius and Decoy at Closing (excluding any proceeds raised in in the Qualified Financing, as defined below). Based on these relative values, before taking into account the dilutive effects of the Qualified Financing, Salarius’ legacy stockholders would retain approximately 14.1% of Salarius on an as-converted-to-common basis and, after giving effect to the exchange ratio and the conversion of the Series A Preferred Stock, Decoy stockholders would own approximately 85.9% of Salarius.
The rights of the Series A Preferred Stock will be set forth in a Certificate of Designation of Preferences, Rights and Limitations that we will file with the Secretary of State of the State of Delaware (the “Certificate of Designation”). The Certificate of Designation provides that the preferred stock will be convertible into shares of Common stock on a 1-for-1000 basis, subject to stockholder approval. Please see “Description of Series A Preferred Stock” for a complete description of the Certificate of Designation and the rights of the Series A Preferred Stock. The Merger was approved by our Board of Directors and the board of directors of Decoy. In addition, following the consummation of the Merger, the Company has agreed to call a special stockholder meeting to approve (i) the conversion of the preferred stock to be issued at the Closing into shares of Common Stock (the “Conversion Proposal”), (ii) a new equity incentive plan in form reasonably agreed to by the parties (the “Equity Plan Proposal”), and (iii) if necessary and advisable, a reverse stock split in a ratio to be approved by our Board of Directors (the “Reverse Stock Split Proposal” and together with the Conversion Proposal and the Equity Plan Proposal, the “Company Stockholder Matters”).
The Merger Agreement contains customary representations and warranties by each of the Company and Decoy, as well as covenants relating to operating each respective business in the ordinary course prior to closing. The closing is conditioned upon, among other things, minimum proceeds from future offerings of at least $6.0 million (collectively, the “Qualified Financing”) and the continued listing of our Common Stock on Nasdaq.
On January 10, 2025, the Company entered into a Warrant Cancellation Agreement. Pursuant to the agreement, a Series A-1 Common Stock Purchase Warrant exercisable for 454,546 shares of the Company's common stock was canceled in exchange for cash of $0.35 million.
The Company issued 286,772 shares of common stock with proceeds of $0.7 million during the period subsequent to December 31, 2024 according to the Purchase Agreement entered into on December 12, 2024 with C/M Capital Master Fund, LP.
The Company issued 24,390 shares of its common stock under the ATM Agreement with Ladenburg Thalmann & Co. Inc in March 2025.

Arrangements between Officers and Directors
To Salarius’ knowledge, there is no arrangement or understanding between any of Salarius’ officers and any other person, including directors, pursuant to which the officer was selected to serve as an officer.
Corporate Governance
Board of Directors
Salarius’ business and affairs are organized under the direction of the Salarius board of directors, which currently consists of seven members. Dr. McVicar currently serves as the Chair of Salarius’ board of directors. The primary responsibilities of Salarius’ board of directors are to provide oversight, strategic guidance, counseling, and direction to Salarius’ management. Salarius’ board of directors meets on a regular basis and additionally as required.
Director Independence
The Nasdaq Listing Rules generally require that a majority of the members of a listed company’s board of directors must qualify as “independent” as affirmatively determined by its board of directors. The Salarius board of directors consults with Salarius’ counsel to ensure that the Salarius board of directors’ determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.
Salarius’ board of directors has undertaken a review of its composition, the composition of its committees and the independence of each director and director nominee. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, Salarius’ board of directors has determined that six of Salarius’ current directors, including Mr. McVicar, Ms. Burleson, Mr. Hanish, Dr. Lammers, Dr. McCreedy and Mr. Lieber, are “independent” as that term is defined under the applicable rules and regulations of the SEC and the listing requirements of Nasdaq.
Salarius’ board of directors has determined that Mr. Arthur, Chief Executive Officer of Salarius in his role as a part-time consultant, is not independent under the applicable rules and regulations of the SEC and Nasdaq Listing Rules. In making these determinations, Salarius’ board of directors considered the current and prior relationships that each non-employee director has with Salarius and all other facts and circumstances Salarius’ board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.
Board Leadership Structure
Our Bylaws provide that if a chair of the Board of Directors is appointed, that person will preside at all meetings of the Board of Directors at which they are present. Currently, the position of chair of our Board of Directors is filled by Dr. McVicar.
The Board of Directors periodically reviews its leadership structure and developments in the area of corporate governance to ensure that this approach continues to strike the appropriate balance for the Company and our stockholders.
Anti-Hedging Policy; Policy on Pledging
We have an insider trading policy that sets forth guidelines and restrictions applicable to transactions involving our stock by our directors, officers and employees. Among other things, this policy prohibits our directors, officers and
employees from engaging in purchases or sales of puts, calls, options or other derivative securities based on the Company’s securities. These hedging transactions are prohibited because they would allow directors, officers and employees to continue to own the covered securities, but without the full risks and rewards of ownership. When that occurs, their interests and the interests of the Company and its stockholders may be misaligned and may signal a message to the trading market that may not be in the best interests of the Company and its stockholders at the time it is conveyed. The insider trading policy also prohibits directors and officers from engaging in short sales of the Company’s securities. Our Insider Trading Policy does not cover transactions of our securities by the Company itself.
Role of our Board of Directors in Risk Oversight
One of the key functions of the Board is informed oversight of our risk management process. Our Board does not have a standing risk management committee, but rather administers this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure and our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements. Our Compensation Committee also assesses and monitors whether our compensation plans, policies, and programs comply with applicable legal and regulatory requirements.
Committees of the Board
Our Board has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. Our Board has adopted a charter for each of these committees, each of which complies with the applicable requirements of current Nasdaq rules. We intend to comply with future requirements to the extent they are applicable to us. Copies of the charters for each committee are available on the investor relations portion of our website at http://investors.salariuspharma.com/corporate-governance/highlights.
Audit Committee
The Audit Committee currently consists of Ms. Burleson, Mr. Hanish, and Mr. Lieber. Mr. Hanish serves as the chair of our Audit Committee. The Board of Directors has determined that each of the members of the Audit Committee satisfies Nasdaq and SEC independence requirements. The Board of Directors has determined that Mr. Hanish qualifies as an audit committee financial expert within the meaning of SEC regulations and meets the financial sophistication requirements of the Nasdaq Listing Rules. In making this determination, the Board of Directors has considered Mr. Hanish’s business background and previous experience. Both our independent registered public accounting firm and management periodically meet with the Audit Committee.
The functions of this committee include, among other things:
•selecting, on behalf of the Board of Directors, an independent public accounting firm to audit our financial statements;

We intend to comply with future requirements to the extent they become applicable to us.

The Board of Directors has determined that each of the members of the Compensation Committee is a non-employee director, as defined in Rule 16b-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Additionally, the Board has determined that each of the members of the Compensation Committee satisfies Nasdaq and SEC independence requirements.
The functions of this committee include, among other things:
•reviewing and approving the corporate objectives that pertain to the determination of executive compensation;
•reviewing and approving the compensation and other terms of employment of our executive officers;

We believe that the composition and functioning of our Compensation Committee complies with all applicable requirements of the Sarbanes-Oxley Act and all applicable SEC and Nasdaq rules and regulations. We intend to comply with future requirements to the extent they become applicable to us.

We believe that the composition and functioning of our Nominating and Corporate Governance Committee complies with all applicable requirements of the Sarbanes-Oxley Act and all applicable SEC and Nasdaq rules and regulations. We intend to comply with future requirements to the extent they become applicable to us.
Board and Committee Meeting Attendance
In 2024, our Board held five meetings. Each of our directors attended at least 75% of the aggregate number of meetings of our Board and meetings of any committee of which he or she was a member, which were held during the time in which he or she was a director or a committee member, as applicable. Our non-management directors meet in regularly scheduled sessions without the presence of management in executive sessions. Our Audit Committee held four meetings, our Compensation Committee held two meetings in 2024 and our Nominating and Corporate Governance Committee held zero meetings in 2024. Directors are encouraged to attend our annual meeting of stockholders, either via webcast or telephonically.
Code of Ethics
The Board has adopted a Code of Business Conduct and Ethics (the “Code of Conduct”) applicable to all of our employees, executive officers, and directors. The Code of Conduct is available on our website at www.salariuspharma.com. Information contained on or accessible through our website is not a part of this report, and the inclusion of our website address in this report is an inactive textual reference only. The Nominating and Corporate Governance Committee is responsible for overseeing the Code of Conduct and must approve any waivers of the Code of Conduct for employees, executive officers, and directors. We expect that any amendments to the Code of Conduct, or any waivers of its requirements, will be disclosed on our website.
We also implemented whistleblower procedures that establish formal protocols for receiving and handling complaints from employees. Any concerns regarding accounting or auditing matters reported under these procedures will be communicated promptly to our Audit Committee.
Director Nominations
Our Board nominates directors for election at each annual meeting of stockholders and elects new directors to fill vacancies when they arise. Our Nominating and Corporate Governance Committee has the responsibility to identify, evaluate, recruit, and recommend qualified candidates to our Board for nomination or election.
Director Criteria. Our Nominating and Corporate Governance Committee has a policy regarding consideration of director candidates recommended by stockholders. Our Nominating and Corporate Governance Committee reviews suggestions for director candidates recommended by stockholders and considers such candidates for recommendation based upon an appropriate balance of knowledge, experience, and capability. In addition to considering an appropriate balance of knowledge, experience, and capability, our Board has as an objective that its membership be composed of experienced and dedicated individuals with diverse backgrounds, perspectives, skills, genders, and ethnicities. Our Nominating and Corporate Governance Committee selects director candidates based on the candidate possessing relevant market and technological expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment, diversity, potential for long-term contribution to the Company’s business, and having the commitment and vision to rigorously represent the long-term interests of the Company’s stockholders. Our Nominating and Corporate Governance Committee believes it is appropriate for a majority of the members of our Board to meet the definition of “independent director” under the Nasdaq rules. Our Nominating and Corporate Governance Committee also believes it appropriate for our Chief Executive Officer to participate as a member of our Board.
Prior to each annual meeting of stockholders, our Nominating and Corporate Governance Committee first identifies nominees by reviewing the current directors whose terms expire at the annual meeting of stockholders and who are willing to continue in service. These candidates are evaluated based on the criteria described above, including as
demonstrated by the candidate’s prior service as a director, and the needs of our Board, with respect to the particular talents and experience of its directors. If a director does not wish to continue in service, the Nominating and Corporate Governance Committee determines not to nominate the director, or a vacancy is created on our Board as a result of a resignation, an increase in the size of our Board or other event, the Nominating and Corporate Governance Committee will consider various candidates for Board membership, including those suggested by members of the Nominating and Corporate Governance Committee, by other members of our Board, by any executive search firm engaged by the Nominating and Corporate Governance Committee, and by stockholders. A stockholder who wishes to suggest a prospective nominee for our Board should notify our Secretary, any member of the Nominating and Corporate Governance Committee, or the persons referenced below in “Communications with our Board of Directors” in writing with any supporting material the stockholder considers appropriate.
Stockholder Nominees.
In addition, our Bylaws contain provisions that address the process by which a stockholder may nominate an individual to stand for election to our Board at our annual meeting of stockholders. In order to nominate a candidate for director, a stockholder must give timely notice in writing to our Secretary and otherwise comply with the provisions of our Bylaws. To be timely, our Bylaws provide that we must have received the stockholder’s notice not more than 120 days nor less than 90 days prior to the anniversary of the previous year’s proxy statement provided in connection with the previous year’s annual meeting of stockholders. Information required by our Bylaws to be in the notice include the name and contact information for the candidate and the person making the nomination and other information about the nominee that must be disclosed in proxy solicitations under Section 14 of the Exchange Act and the related rules and regulations under that section.
Stockholder nominations must be made in accordance with the procedures outlined in, and include the information required by, our Bylaws and must be addressed to: Secretary, Salarius Pharmaceuticals, Inc., 2450 Holcombe Blvd. Suite X, Houston, TX 77021. You can obtain a copy of our Bylaws by writing to the Secretary at this address.
Meetings of Our Independent Directors and Communications with our Board of Directors
During meetings of the Board, the independent directors meet regularly in an executive session without management or management directors present. The purpose of these executive sessions is to promote open and candid discussion among the non-management directors. Our Board recommends that stockholders and other interested parties initiate communications with our Board, the independent directors, the Chair, or any committee of our Board in writing to the attention of our Secretary, Salarius Pharmaceuticals, Inc., 2450 Holcombe Blvd. Suite X, Houston, TX 77021. This process will assist our Board in reviewing and responding to stockholder communications in an appropriate manner. Our Board has instructed our Secretary to review such correspondence and, at his discretion, not to forward items if he deems them to be of a commercial or frivolous nature or otherwise inappropriate for our Board’s consideration such as spam, junk mail and mass mailings, product complaints, personal employee complaints, product inquiries, new product suggestions, resumes and other forms of job inquiries, surveys, business solicitations, or advertisements.

Narrative Disclosure to Summary Compensation Table
In the process of determining compensation for Salarius’ named executive officers, the Compensation Committee considers the current financial position of Salarius, the strategic goals of Salarius, and the performance of each of Salarius’ named executive officers. In addition, from time to time, the Compensation Committee considers the various components (described below) of Salarius’ compensation program for executives in relation to compensation paid by other public companies, compensation data, their historical review of all executive officer compensation, and recommendations from Salarius Chief Executive Officer (other than for his own salary). The Compensation Committee has the sole authority to select, compensate and terminate its external advisors.
The Compensation Committee utilizes the following components of compensation (described further below) to strike an appropriate balance between promoting sustainable and excellent performance and discouraging any excessive risk-taking behavior:
•Base Salary;
•Non-equity incentive plan compensation;
•Annual long-term equity compensation;
•Personal benefits and perquisites; and
•Acceleration and severance agreements tied to changes in control of Salarius.
Base Salaries
Salarius’ named executive officers receive base salaries as set forth in their respective employment or consulting agreements. Each named executive officer is eligible for annual raises subject to review and approval of the Compensation Committee. There were no salary raises in 2024. Mr. Arthur’s base salary was $500,000 for the portion of 2024 during which he served as an employee and, following his termination, Mr. Arthur received $10,417 per month pursuant to the terms of his consulting agreement. Mr. Rosenblum’s base salary was $330,000 for 2024.
Non-Equity Incentive Plan Compensation
Target bonuses are reviewed annually and established as a percentage of the executives’ base salaries, generally based upon seniority of the officer and targeted at or near the median of the peer group (with reference to Salarius’ corporate compensation philosophy) and relevant survey data. Each year, the Compensation Committee establishes corporate and individual objectives and respective target percentages, taking into account recommendations from Salarius’ Chief Executive Officer as it relates to executive positions other than the Chief Executive Officer’s compensation. Salarius’ Chief Executive Officer’s target bonus is set by the Compensation Committee to align entirely with Salarius’ overall corporate objectives. At the end of each fiscal year-end, Salarius’ Chief Executive Officer provides the Compensation Committee with a written evaluation showing actual performance as compared to corporate and/or individual objectives, and the Compensation Committee uses that information, along with the overall corporate performance, to determine what percentage of each executive’s bonus target will be paid out as a bonus for that year. Overall, the Compensation Committee seeks to establish the corporate and individual functional goals to be highly challenging yet attainable.
Mr. Arthur’s and Mr. Rosenblum’s target bonus’ for both 2024 and 2023 as a percentage of base salary was 50% and 35% respectively. Neither named executive officer received a bonus for Salarius’ 2023 and 2024 fiscal years.
Long-Term Equity Compensation
Salarius designed its long-term equity grant program to further align the interests of its executives with those of its stockholders and to reward the executives’ longer-term performance. Historically, the Compensation Committee has granted stock options, although from time-to-time, to further increase the emphasis on compensation tied to performance, the Compensation Committee may grant other equity awards as allowed by the Salarius Pharmaceuticals 2015 Equity Incentive Plan. The Compensation Committee may grant stock options, restricted stock, restricted stock units and similar equity awards permitted under Salarius’ plans based on its judgment as to whether the complete compensation packages to Salarius’ executives, including prior equity awards, are appropriate and sufficient to retain and incentivize the executives and whether the grants balance long-term versus short-term compensation. The Compensation Committee also considers Salarius’ overall performance as well as the individual performance of each of Salarius’ named executive officers, the potential dilutive effect of restricted stock awards, the dilutive and overhang effect of the equity awards, and recommendations from the Chief Executive Officer (other than with respect to his own equity awards).
Stock options are granted with an exercise price equal to the fair market value of Salarius’ common stock on the date of grant.
Restricted stock is granted at the closing price of Salarius’ common stock on the grant date.
On February 20, 2024, the Compensation Committee granted Mr. Rosenblum an option to purchase 2,813 shares of Salarius common stock at an exercise price of $4.5688 per share. 25% of the options vests on February 20, 2025 and the remaining 1/36 of the remaining option vests on each monthly anniversary thereafter for 36 months.
On April 11, 2024, the Compensation Committee granted Mr. Arthur an option to purchase 2,563 shares of Salarius common stock at an exercise price of $4.08 per share. 100% of the option vest on April 11, 2025.
Personal Benefits and Perquisites
All of Salarius’ executives are eligible to participate in Salarius’ employee benefit plans, including medical, dental, vision, life insurance, short-term and long-term disability insurance, flexible spending accounts, 401(k), and an employee stock purchase program. These plans are available to all full-time employees. In keeping with Salarius’ philosophy to provide total compensation that is competitive within Salarius’ industry, Salarius offers limited personal
benefits and perquisites to its executive officers. You can find more information on the amounts paid for these perquisites to or on behalf of Salarius’ named executive officers in Salarius’ Summary Compensation Table.
Nonqualified Deferred Compensation
None of Salarius’ named executive officers participates in or has account balances in nonqualified defined contribution plans or other nonqualified deferred compensation plans maintained by Salarius. Salarius’ board of directors may elect to provide its officers and other employees with nonqualified defined contribution or other nonqualified deferred compensation benefits in the future if it determines that doing so is in Salarius’ best interests.

Employment and Separation Agreements
Below are descriptions of the employment or separation agreements with Salarius’ named executive officers. Furthermore, each of Salarius’ executive officers has executed a form of Salarius’ standard proprietary information and inventions assignment agreement.
David J. Arthur Separation Agreement
On February 20, 2024 (the “Separation Date”), Salarius entered into a separation and release agreement (the “Separation Agreement”) with David J. Arthur, Salarius’ President and Chief Executive Officer, which provides for Mr. Arthur’s separation of employment, effective as of the Separation Date. Under the Separation Agreement, Salarius paid Mr. Arthur a lump-sum payment equal to the amounts owed to him pursuant to Section 5(c)(ii) of that certain Amended and Restated Employment Agreement. Under the terms of the Separation Agreement, Mr. Arthur elected to receive such amounts in a lump sum.

Pursuant to the Consulting Agreement, Mr. Arthur is required to devote at least one-fourth (1/4) of his time on a weekly basis (on average 10 or more hours/week) to performing the services set forth in the Consulting Agreement. In exchange for Mr. Arthur’s services as set forth in the Consulting Agreement, Mr. Arthur will receive $10,417 per month. The term of the Consulting Agreement expires on February 20, 2025, unless earlier terminated by either party in accordance with the terms of the Consulting Agreement. On February 20, 2025, Salarius entered into the Amendment 1 to the Consulting Agreement (the "Amendment"). In exchange for Mr. Arthur’s services as set forth in the Amendment, Mr. Arthur will receive $500 per hour.
In addition, on the Separation Date, Salarius entered into a Notice of Stock Option Amendment with Mr. Arthur (the “Notice of Stock Option Amendment”), pursuant to which the Salarius board of directors amended the stock options to purchase shares of common stock granted to Mr. Arthur on September 10, 2019, March 23, 2020, July 14, 2020, December 2, 2020 and January 20, 2022 pursuant to Salarius’ 2015 Equity Incentive Plan (the “Plan”) to extend the post-termination exercise period from 90 days to 18 months upon the termination of Mr. Arthur’s “Continuous Service” (as defined in the Plan) for any reason other than for “Cause” (as defined in the Plan), but not beyond the term of the applicable stock option, and subject to earlier termination (such as in connection with a “Corporate Transaction” (as defined in the Plan) as provided under the Plan.
Mr. Arthur also entered into an updated indemnification agreement with Salarius (the “Indemnification Agreement”) to reflect his change in status from an employee of Salarius to a consultant.
Mark J. Rosenblum
On April 24, 2020, Salarius entered into an Executive Employment Agreement with Mark J. Rosenblum, its Executive Vice President of Finance and Chief Financial Officer (the “Rosenblum Agreement”). Under the Rosenblum Agreement, Mr. Rosenblum was originally entitled to an annual base salary of $265,000. Mr. Rosenblum is also eligible to participate in, subject to applicable eligibility requirements, all of Salarius’ benefits plans and fringe benefits and programs that may be provided to Salarius executives from time to time. In December 2021 Mr. Rosenblum’s base salary was increased to $300,000, which increase became effective January 1, 2022. In November 2022 Mr. Rosenblum’s base salary was increased to $330,000, which increase became effective January 1, 2023. On February 20, 2024, Salarius entered into an amendment to the Rosenblum Agreement to provide Mr. Rosenblum with the option to receive any severance that may be owed to him pursuant to Section 5(c)(i) thereof in equal installments over a period of time or in a lump-sum amount.
Clawback Policy
Salarius has a compensation recoupment, or clawback, policy, which Salarius adopted to comply with Nasdaq listing standards implementing Exchange Act Rule 10D-1. The clawback policy includes mandatory recoupment of excess incentive-based compensation received by a covered executive (including the Named Executive Officers) on or after October 2, 2023 in the event of a restatement of Salarius’ financial statements due to material non-compliance with any financial reporting requirement under federal securities laws, as required by Exchange Act Rule 10D-1.
Additional Narrative Disclosure: Termination-Based Compensation
The Rosenblum Agreement provides that, so long as Mr. Rosenblum executes a release and settlement agreement with Salarius, and subject to applicable withholdings, he would be entitled to receive a cash severance and an amount for premium payments under COBRA. Under the Rosenblum Agreement, the cash severance is equal to 9 months and if Mr. Rosenblum elects continuation coverage under COBRA or state law equivalent or enrollment in an individual marketplace, Salarius will pay him an amount equal to the 9 months’ worth of total premium payments (or until the date the executive secures reasonably comparable coverage with another employer, if sooner). These payments to Mr. Rosenblum are required to be made upon the following termination events:
•In the event Salarius or a successor entity terminates the executive’s employment for any reason other than a termination for Cause, or in connection with death, a permanent disability, or Salarius’ dissolution; and
•In the event that, within the 18-month period following a Change in Control of Salarius or a successor entity terminates the executive’s employment for any reason other than a termination for Cause or in connection with death, a permanent disability, or Salarius’ dissolution, or if the executive terminates his employment for Good Reason.
The following definitions have been adopted in the Rosenblum Agreement:
“for Cause” shall be determined by the board of directors by a majority vote (not including such employee with respect to an event related to him) and shall mean:
•any material breach, which is not cured within 30 days after written notice thereof, of the terms of Rosenblum Agreement by the executive, or the failure of the executive to diligently and properly perform his duties, or the executive’s failure to achieve the objectives specified by the board of managers;
•the executive’s misappropriation or unauthorized use of the tangible or intangible property of Salarius, or any other similar agreement regarding confidentiality, intellectual property rights, non-competition or non-solicitation;
•any material failure to comply with Salarius company policies or any other policies and/or directives of the board of managers, which failure is not cured within 30 days after written notice thereof, provided that no cure period is available for a failure to comply with policies related to harassment, unlawful discrimination, retaliation or workplace violence;
•the executive’s use of illegal drugs or any illegal substance, or alcohol in any manner that materially interferes with the performance of his duties under the Rosenblum Agreement;
•any dishonest or illegal action (including, without limitation, embezzlement) or any other action by the executive which is materially detrimental to the interest and well-being of Salarius, including, without limitation, harm to its reputation;
•the executive’s failure to fully disclose to Salarius any material conflict of interest he may have in a transaction between Salarius and any third party which is materially detrimental to the interest and well-being of Salarius; or
•any adverse action or omission by the executive which would be required to be disclosed pursuant to public securities laws or which would limit the ability of Salarius or its affiliates to sell securities under any Federal or state law or which would disqualify Salarius or its affiliates from any exemption otherwise available to it.
“Good Reason” means the occurrence of any of the following actions taken by Salarius without the executive’s consent, but only if (a) the executive informs Salarius within 90 days of its occurrence that an event constituting Good Reason has occurred, (b) Salarius fails to cure the event within 90 days of such notice, and (c) the executive terminates his employment within 6 months of the initial occurrence:
•for a period of twelve months immediately following a Change of Control, or the “Post-COC Period,” his salary, bonus or equity are reduced or diminished, or his duties and responsibilities or position are reduced or diminished to less than an executive “C” level position;
•any time after the Post-COC Period, the executive’s salary, bonus or equity are reduced or diminished, or his duties and responsibilities or position are reduced when compared to his duties and responsibilities immediately prior to Change of Control;
•Salarius materially breaches its obligations under the applicable Rosenblum Agreement; or
•the executive is required to relocate by more than 50 miles outside the extraterritorial jurisdiction of Houston, Texas.
“Change in Control” means (i) a financing transaction or any transaction designed to raise money for Salarius’ continuing operations or any sale, exchange, transfer, or issuance, or related series of sales, exchanges, transfers, or issuances, of Salarius’ equity units by Salarius or any holder thereof, in which the holders of Salarius’ equity units immediately prior to such transaction or event no longer hold beneficial ownership of at least fifty percent (50%) of Salarius’ outstanding equity units immediately after any such transaction or event; or (ii) a significant transaction involving the out-licensing of Salarius’ lead clinical asset, a sale of substantially all of Salarius’ assets, or Salarius’ liquidation or dissolution.

Director Compensation Arrangements
Salarius’ non-employee director compensation is comprised of cash compensation and equity compensation. Further, Salarius reimburses all of its non-employee directors for their reasonable expenses incurred in attending meetings of Salarius’ board of directors and committees of the Salarius board of directors.
Generally, Salarius’ board of directors believes that the level of director compensation should be based on time spent carrying out board of directors and committee responsibilities and be competitive with comparable companies. In addition, the Salarius board of directors believes that a significant portion of director compensation should align director interests with the long-term interests of stockholders. The Salarius board of directors makes changes in its director compensation practices only upon the recommendation of the Compensation Committee, and discussion and approval by the Salarius board of directors.
Salarius’ board of directors, following the Compensation Committee’s recommendation, has approved the compensation of Salarius’ non-employee directors, as described below. The Compensation Committee believes that its non-employee director compensation remains aligned with director compensation practices at Salarius’ peer companies while considering the ongoing cash constraints of Salarius.
Cash Compensation
On February 20, 2024, the Salarius board of directors approved a reduction in cash compensation payable to its non-employee directors. Effective as of April 1, 2024, non-employee directors receive an annual cash retainer of $30,000 (previously $40,000) for their board of directors service. In addition, the Chair of the board of directors receives an additional annual cash retainer of $20,000 (previously $40,000), the Chair of the Audit Committee of the board of directors receives an additional annual cash retainer of $10,000 (previously $20,000), and members of the Audit Committee will receive an additional annual cash retainer of $3,500 (previously $7,500). No additional cash retainers will be paid for serving as a Chair or member of the Compensation Committee of the board of directors or the Governance and Nominating Committee of the board of directors. Mr. Arthur is eligible to receive compensation as a non-employee member of the board of directors.

Salarius Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Nonpublic Information
Salarius does not have any formal policy that requires Salarius to grant, or avoid granting, equity-based compensation to its executive officers at certain times. Consistent with its annual compensation cycle, the Compensation Committee has for several years granted annual equity awards to its executive officers in February of each year. The timing of any equity grants to executive officers in connection with new hires, promotions, or other non-routine grants is tied to the event giving rise to the award (such as an executive officer’s commencement of employment or promotion effective date). As a result, in all cases, the timing of grants of equity awards, including stock options, occurs independent of the release of any material nonpublic information, and Salarius does not time the disclosure of material nonpublic information for the purpose of affecting the value of equity-based compensation.
The following table presents information regarding stock options issued to certain of Salarius’ executive officers in 2024 during any period beginning four business days before the filing of a periodic report or current report disclosing material non-public information and ending one business day after the filing or furnishing of such report with the SEC.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS
Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters
The following table sets forth information as of March 17, 2025 regarding the number of shares of common stock and the percentage of common stock, beneficially owned by:
•each person, or group of affiliated persons, known by Salarius to beneficially own more than 5% of its common stock;
•each of Salarius’ directors;
•each of Salarius’ named executive officers; and
•all of Salarius’ current executive officers and directors as a group.
The percentage ownership is based on 1,745,730 shares of common stock outstanding on March 17, 2025. Salarius has determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment
power with respect to those securities. In addition, the rules include shares of Salarius’ common stock issuable pursuant to the exercise of stock options or warrants or other securities (including out-of-the-money securities) that are either immediately exercisable or exercisable or vest within 60 days of March 17, 2025. These shares are deemed to be outstanding and beneficially owned by the person holding those options, warrants, or securities for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.
Except as otherwise noted below, the address for each person or entity listed in the table is c/o Salarius Pharmaceuticals, Inc., 2450 Holcombe Blvd., Suite X, Houston, TX 77021.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
Item 13. Certain Relationships and Related Transactions, and Director Independence
The following includes a summary of transactions since January 1, 2023 to which Salarius been a party, in which the amount involved in the transaction exceeded the lesser of $120,000 or one percent of the average of Salarius’ total assets at year-end for the last two completed fiscal years, and in which any of Salarius’ directors, executive officers or, to Salarius’ knowledge, beneficial owners of more than 5% of Salarius’ capital stock or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest, other than
equity and other compensation, termination, change of control, and other arrangements, which are described under “Executive Compensation.”
DeuteRx Transaction
On January 12, 2022, Salarius entered into an Acquisition and Strategic Collaboration Agreement (the “ASCA”), with DeuteRx, LLC, a Delaware limited liability company (the “DeuteRx”), pursuant to which DeuteRx agreed to sell, and Salarius agreed to purchase certain assets of DeuteRx, including the development product Salarius refers to as DRX-3164 (collectively, the “Purchased Assets”). Dr. McVicar, a member of the Salarius board of directors, serves as a consultant to DeuteRx and is a consultant to an affiliate of DeuteRx.
The Purchased Assets were purchased for an aggregate purchase price of $1,500,000 and the delivery of 5,000 shares of Salarius’ common stock. Salarius also agreed to pay to DeuteRx (i) milestone payments upon the occurrence of certain events and (ii) royalty payments.
Indemnification Agreements
Salarius has entered, and intends to continue to enter, into separate indemnification agreements with its directors and executive officers, in addition to the indemnification provided for in its Certificate of Incorporation and Bylaws. These agreements, among other things, require Salarius to indemnify its directors and executive officers for certain expenses, including attorneys’ fees, judgments, fines, and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of Salarius’ directors or executive officers or as a director or executive officer of any other company or enterprise to which the person provides services at Salarius’ request. Salarius believes that these charter provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers.
The limitation of liability and indemnification provisions in Salarius’ Certificate of Incorporation and Bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit Salarius and its stockholders. A stockholder’s investment may decline in value to the extent Salarius pays the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.
Policies and Procedures for Transactions with Related Persons
Salarius has adopted a written Related Person Transactions Policy that sets forth its policies and procedures regarding the identification, review, consideration, and oversight of “related person transactions.” For purposes of this policy only, a “related person transaction” is a transaction, arrangement, or relationship (or any series of similar transactions, arrangements or relationships) in which Salarius or any of its subsidiaries are participants involving an amount that exceeds $120,000, in which any “related person” has a material interest.
Transactions involving compensation for services provided to Salarius as an employee, consultant, or director are not considered related person transactions under this policy. A related person is any executive officer, director, nominee to become a director or a holder of more than 5% of any class of Salarius’ voting securities (including its common stock), including any of their immediate family members and affiliates, including entities owned or controlled by such persons.
Under the policy, the related person in question or, in the case of transactions with a holder of more than 5% of any class of Salarius’ voting securities, an officer with knowledge of the proposed transaction, must present information regarding the proposed related person transaction to Salarius’ Audit Committee (or, where review by the Audit Committee would be inappropriate, to another independent body of the Salarius board of directors) for review. To identify related person transactions in advance, Salarius relies on information supplied by its executive officers, directors, and certain significant stockholders. In considering related person transactions, Salarius’ Audit Committee considers the relevant available facts and circumstances, which may include, but not limited to:
•the risks, costs, and benefits to Salarius;
•the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated;
•the terms of the transaction;
•the availability of other sources for comparable services or products; and
•the terms available to or from, as the case may be, unrelated third parties.
Salarius’ Audit Committee will approve only those transactions that it determines are fair to Salarius and in its best interests.
Director Independence
See Item 10 "Directors, Executive Officers, and Corporate Governance" for additional information regarding director independence.

During the approval process, the Audit Committee considers the impact of the types of services and the related fees on the independence of the registered public accountant.
