Current report

The March Purchase Agreement contains customary representations and warranties and agreements of us and the March Investor and customary indemnification rights and obligations of the parties. Pursuant to the terms of the March Purchase Agreement, we have agreed to certain restrictions on the issuance and sale of its Common Stock or Common Stock Equivalents (as defined in the March Purchase Agreement) during the 30-day period following the closing of the Registered Offering (the “Lock-up Period”). Additionally, we agreed not to enter into a variable rate transaction for a period of one year following the closing of the March Registered Offering, provided, however, that following the Lock-up Period, (i) we may enter into and/or issue shares of Common Stock in an “at-the-market” facility with Wainwright (as defined below) as sales agent, and (ii) we may enter into, or effect a transaction under, an equity line of credit.

Current report

purchase up to an aggregate of 8,235,000 shares of Common Stock. The Series F Warrants will have an exercise price of $0.40 per share and will be exercisable commencing on the effective date of stockholder approval of the issuance of the shares of Common Stock issuable upon exercise of the Series F Warrants (the “Stockholder Approval”) and will expire twenty-four months following the date of Stockholder Approval. We will be obligated to obtain Stockholder Approval at the Company's annual meeting of stockholders on or prior to the date that is 150 days following the closing date (the “Stockholder Meeting Deadline”). If Stockholder Approval is not obtained on or prior to the Stockholder Meeting Deadline, we are required to cause an additional stockholder meeting to be held every 60 days after the Stockholder Meeting Deadline until Stockholder Approval is obtained or the Series F Warrants are no longer outstanding. The Series F Warrants and the shares of our Common Stock issuable upon the exercise of the Series F Warrants are not being registered under the Securities Act of 1933, as amended (the “Securities Act”), were not offered pursuant to the Registration Statement and were offered pursuant to the exemption provided in Section 4(a)(2) under the Securities Act, and Rule 506(b) promulgated thereunder.

Current report

On February 24, 2025, we received a letter from The Nasdaq Stock Market notifying us that for the preceding 31 consecutive business days our common stock did not maintain a minimum closing bid price of $1.00 per share as required by Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). The notice has no immediate effect on the listing or trading of our common stock, and the common stock will continue to trade on The Nasdaq Capital Market under the symbol “ACXP” at this time.

Current report

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have a grace period of 180 calendar days, or until August 25, 2025, to regain compliance with Nasdaq Listing Rule 5550(a)(2). Compliance can be achieved automatically and without further action if the closing bid price of our common stock is at or above $1.00 for a minimum of 10 consecutive business days at any time during the 180-day compliance period, in which case Nasdaq will notify us of our compliance and the matter will be closed.

Current report

If, however, we do not achieve compliance with the Minimum Bid Price Requirement by August 25, 2025, we may be eligible for additional time to comply. In order to be eligible for such additional time, we will be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the Minimum Bid Price Requirement, and must notify Nasdaq in writing of our intention to cure the deficiency during the second compliance period, by effecting a reverse stock split, if necessary. However, if it appears to Nasdaq that we will not be able to cure the deficiency, or if we are otherwise not eligible, Nasdaq will provide notice that our common stock will be subject to delisting. We would then be entitled to appeal that determination to a Nasdaq hearings panel.

Current report

We intend to actively monitor the bid price of our common stock and will consider available options to regain compliance with the Minimum Bid Price Requirement. However, there can be no assurance that we will be able to regain compliance with the Minimum Bid Price Requirement or that Nasdaq will grant us a further extension of time to regain compliance, if applicable.

For extended clinical cure, data also showed that 100% (5 of 5) of ibezapolstat-treated patients who agreed to observation for up to three months following CC at EOT experienced no recurrence of infection;

Current report

We convened an End-of-Phase 2 Meeting with the FDA on April 17, 2024 and announced on May 15, 2024 that we had a successful meeting, including confirmation of Phase 3 readiness for ibezapolstat for the treatment ofC. difficile infection. Agreement with the FDA was reached on key elements to move forward with our international Phase 3 clinical trial program. Agreement was also reached with the FDA on the complete non-clinical and clinical development plan for filing of a New Drug Application (“NDA”) for marketing approval. Planning continues to advance ibezapolstat into international Phase 3 clinical trials for treatment ofC. difficileinfection (“CDI”).

Current report

In July 2024, we announced that a new patent has been granted by the United States Patent and Trademark Office (“USPTO”). This patent relates to ibezapolstat and its use to treatC. difficile infection while reducing the recurrence of the infection, as well as improving the health of the gut microbiome. This is the latest in the series of granted patents and pending patent applications that we have filed to protect our proprietary technologies in the field of antimicrobials.

Current report

Following our successful End-of-Phase 2 Meeting with the FDA in August 2024, which confirmed our Phase 3 clinical trial readiness, and per the FDA regulatory requirements, in August 2024, we submitted our request to the FDA for a meeting to review our manufacturing processes and specifications for drug substance and final project and packaging (typically referred to as Chemistry, Manufacturing and Controls (“CMC”)) for our Phase 3 clinical trials. In December 2024, we received written positive feedback from FDA regarding acceptability of our CMC plan and data package proposed to support the Phase 3 clinical program. In January 2025, we received positive written responses from the EMA under its Scientific Advice Procedure that the clinical, non-clinical and CMC information package submitted supports advancement of the ibezapolstat Phase 3 program. The responses also included guidance on ibezapolstat’s regulatory pathway for a Marketing Authorization Application in the EU for ibezapolstat in CDI.

Previous report

On October 2, 2023, we discontinued our Phase 2b clinical trial of our lead antibiotic candidate, ibezapolstat, targeting the treatment of patients with CDI and anticipate advancing to Phase 3 clinical trials more expeditiously than originally planned. We made the decision to discontinue the Phase 2b clinical trial in consultation with our medical and scientific advisors and statisticians based upon observed aggregate blinded data and other factors, including the cost to maintain clinical trial sites and slow enrollment due to COVID-19.

Previous report

We determined that the Phase 2b clinical trial has performed as anticipated for each of ibezapolstat, our lead antibiotic candidate, and vancomycin, the control agent and a standard of care to treat patients with CDI, with high rates of clinical cure observed across the trial and no emerging safety concerns reported to date. Accordingly, the Independent Data Monitoring Committee will not be required to perform an interim analysis of the Phase 2b clinical trial data as originally planned but is supportive of our decision to early discontinue the Phase 2b clinical trial and will remain involved for our Phase 3 clinical trials. Prior to discontinuing the Phase 2b clinical trial, we notified FDA of its decision to early discontinue the trial. The trial was not discontinued due to safety concerns.

Previous report

We are currently preparing for an End-of-Phase 2 Meeting with FDA and advancement to Phase 3.

Previous report

In connection with the 2023 Offerings, we also entered into a Warrant Amendment Agreement with the 2023 Investor. Under the Warrant Amendment Agreement, we amended its existing series A warrants to purchase up to an aggregate of 1,230,769 shares of our common stock and series B warrants to purchase up to an aggregate of 1,230,769 shares of our common stock (collectively, the “Existing Warrants”) that were previously issued in July 2022, such that effective upon the closing of the 2023 Offerings, the Existing Warrants were amended to have a termination date of May 18, 2029.

Previous report

On May 16, 2023, we entered into a placement agency agreement (the “2023 Placement Agent Agreement”) with Maxim Group LLC (the “Placement Agent”) pursuant to which we engaged Maxim as the placement agent in connection with the 2023 Offerings. The Placement Agent agreed to use its reasonable best efforts to arrange for the sale of the Securities. We paid the Placement Agent a placement agent fee in cash equal to 5.75% of the gross proceeds from the sale of the Shares, Warrants and Pre-Funded Warrants. We also reimbursed the Placement Agent for all reasonable travel and other out-of-pocket expenses, including the reasonable fees of legal counsel not to exceed $50,000. The 2023 Placement Agent Agreement also contained representations, warranties, indemnification and other provisions customary for transactions of this nature.

Previous report

Public health crises such as pandemics or similar outbreaks could adversely impact our business. Notably, the COVID-19 pandemic continues to evolve. The extent to which COVID-19 impacts our operations or those of our collaborators, vendors, contractors, suppliers, clinical trial sites and other material business relations and governmental agencies will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the ultimate duration of the outbreak, new information that will emerge concerning the severity of the virus and the actions to contain it or treat its impact, among others. Previously, our clinical trial operations were directly and indirectly impacted, and could continue to be directly and indirectly impacted, by the COVID-19 pandemic. While the potential economic impact brought by, and the ultimate duration of, the COVID-19 pandemic, have been, and continue to be, difficult to assess or predict, the spread of COVID-19 has caused a broad impact globally. The extent to which the COVID-19 pandemic may impact our business continues to be highly uncertain and cannot be predicted with confidence.

Previous report

The Financial Accounting Standards Board has issued certain accounting pronouncements as of December 31, 2023 that will become effective in subsequent periods; however, we do not believe that any of those pronouncements would have significantly affected our financial accounting measurements or disclosures had they been in effect during 2023, or that they will have a significant impact on us at the time they become effective.

Previous wording

Acurx Pharmaceuticals, Inc., (the “Company”), a Delaware corporation, formerly Acurx Pharmaceuticals, LLC (the “Company”) is a clinical stage biopharmaceutical company developing a new class of antibiotics for infections caused by bacteria listed as priority pathogens by the World Health Organization (“WHO”), the U.S. Centers for Disease Control and Prevention (“CDC”) and the U.S. Food and Drug Administration (“FDA”). Priority pathogens are those which require new antibiotics to address the worldwide crisis of antimicrobial resistance (“AMR”) as identified by the WHO, CDC and FDA. The CDC estimates that, in the U.S., antibiotic-resistant pathogens infect one individual every 11 seconds and result in one death every 15 minutes. The WHO recently stated that growing antimicrobial resistance is equally as dangerous as the ongoing COVID-19 pandemic, threatens to unwind a century of medical progress and may leave us defenseless against infections that today can be treated easily. According to the WHO, the current clinical development pipeline remains insufficient to tackle the challenge of the increasing emergence and spread of antimicrobial resistance.

The CDC estimates that, in the U.S., antibiotic-resistant pathogens infect one individual every 11 seconds and result in one death every 15 minutes. According to the WHO Fact Sheet (November 2023) Antimicrobial Resistance (AMR) is one of the top global public health and development threats. It is estimated that bacterial AMR was directly responsible for 1.27 million global deaths in 2019 and contributed to 4.95 million deaths. Furthermore, the world faces an antibiotics pipeline and access crisis. There is an inadequate research and development pipeline in the face of rising levels of resistance, and urgent need for additional measures to ensure equitable access to new and existing vaccines, diagnostics and medicines.

Previous wording

Prior to that, we completed our Phase 2a clinical trial of ibezapolstat to treat patients with CDI and reported the top-line data in November 2020. The Phase 2a clinical trial was terminated early based upon the recommendation of our Scientific Advisory Board (the “SAB”). The SAB reviewed the study data presented by management, including adverse events and efficacy outcomes, and discussed its clinical impressions. The SAB unanimously supported the early termination of the Phase 2a trial after 10 patients were enrolled in the trial instead of 20 patients as originally planned. The early termination was further based on the evidence of meeting the treatment goals of eliminating the infection with an acceptable adverse event profile.

maintained for 48 hours after end of treatment. Such cure was sustained, meaning that the patients showed no sign of infection recurrence, for 30 days thereafter. This constitutes a 100% response rate for the primary and secondary endpoints of the trial. All 10 patients enrolled in the Phase 2a trial met the study’s primary and secondary efficacy endpoints, namely, Clinical Cure at end of treatment and Sustained Clinical Cure of no recurrence of CDI at the 28-day follow-up visit. No treatment-related serious adverse events (“SAEs”) were reported by the investigators who enrolled patients in the trial. We believe these results represent the first-ever clinical data showing pol IIIC has potential as a therapeutically relevant antibacterial target. Our Phase 2b clinical trial commenced enrollment on December 3, 2021.

Current wording

The SAB noted that 10 out of 10 patients enrolled in the Phase 2a trial reached the Clinical Cure endpoint, defined in the study protocol as the resolution of diarrhea in the 24-hour period immediately before the end of treatment that is maintained for 48 hours after end of treatment. Such cure was sustained, meaning that the patients showed no sign of infection recurrence, for 30 days thereafter. This constitutes a 100% response rate for the primary and secondary endpoints of the trial. All 10 patients enrolled in the Phase 2a trial met the study’s primary and secondary efficacy endpoints, namely, Clinical Cure at end of treatment and Sustained Clinical Cure of no recurrence of CDI at the 28-day follow-up visit.

On March 6, 2025, we, entered into a Securities Purchase Agreement (the “March Purchase Agreement”) with an institutional investor named therein (the “March Investor”), pursuant to which we agreed to issue and sell, in a registered direct offering by us directly to the March Investor (the “March Registered Offering”) (i) 2,150,000 shares of common stock, par value $0.001 per share (the “Common Stock”), at a purchase price of $0.40 per share and (ii) pre-funded common stock purchase warrants (the “March Pre-Funded Warrants”) to purchase up to 595,000 shares of Common Stock (the “March Pre-Funded Warrant Shares”) at a purchase price of $0.3999 per March Pre-Funded Warrant for aggregate gross proceeds of approximately $1.1 million, before deducting the placement agent fees and related offering expenses. We intend to use the net proceeds from the offering for working capital and other general corporate purposes.

Previous wording

The gross proceeds to us from the 2023 Registered Offering were approximately $4.0 million and net proceeds after deducting the placements agent’s fees and other offering expenses payable by us were approximately $3.5 million. The securities were offered by us pursuant to a registration statement on Form S-3 (File No. 333-265956) previously filed with the SEC on July 1, 2022, and which was declared effective by the SEC on July 11, 2022.

Current wording

Previous wording

On November 2, 2023, we announced top-line Phase 2 efficacy and safety results from the clinical trial of ibezapolstat in patients with CDI. The overall observed Clinical Cure rate in the combined Phase 2 trials in patients with CDI was 96% (25 out of 26 patients), based on 10 out of 10 patients (100%) in Phase 2a in the modified intent to treat population, plus 15 out of 16 (94%) patients in Phase 2b in the per protocol population, who experienced Clinical Cure during treatment with ibezapolstat. Ibezapolstat was well-tolerated, with three patients each experiencing one mild adverse event assessed by the blinded investigator to be drug-related. All three events were gastrointestinal in nature and resolved without treatment. There were no drug-related treatment withdrawals or no drug-related serious adverse events, or other safety findings of concern. In the Phase 2b vancomycin control arm, 14 out of 14 patients experienced clinical cure. We believe that based on the pooled Phase 2 ibezapolstat clinical cure rate of 96% and the historical vancomycin cure rate of approximately 81% (Vancocin® Prescribing Information, January 2021), we will demonstrate non-inferiority of ibezapolstat to vancomycin in Phase 3 trials in accordance with the applicable FDA Guidance for Industry (October, 2022). The Phase 2b clinical trial met the protocol primary objective of assessing the primary efficacy endpoint of the Clinical Cure rate after 10 days of oral treatment. Further analyses will be forthcoming regarding secondary and exploratory endpoints, including Sustained Clinical Cure data, Extended Clinical Cure data up to 94 days and comparative effects on the gut microbiome.

Current wording

On November 2, 2023, we announced top-line results from the Phase 2b segment of our Phase 2 clinical trial of ibezapolstat in patients with CDI. In the Phase 2b segment of the clinical trial, the observed Clinical Cure rate in the per protocol population was 15 of 16 patients (94%) in the ibezapolstat arm and 14 out of 14 patients (100%) in the vancomycin arm, respectively. In the Phase 2a segment of the clinical trial that evaluated ibezapolstat in patients with CDI, the observed Clinical Cure rate in the per protocol population was 10 out of 10 patients (100%). In a post hoc analysis conducted with the data available at the time of discontinuation of the trial, the overall observed Clinical Cure rate for ibezapolstat in the combined Phase 2a and Phase 2b segments of the clinical trial in patients with CDI was 96% (25 out of 26 patients), based on 10 out of 10 patients (100%) in the Phase 2a segment in the per protocol population, plus 15 out of 16 (94%) patients in the Phase 2b segment We believe that, based on the post hoc pooled Phase 2 ibezapolstat Clinical Cure rate of 96% and the historical vancomycin cure rate of approximately 81% (Vancocin® Prescribing Information, January 2021), Phase 3 trials conducted in accordance with the applicable FDA Guidance for Industry (October 2022) would be able to demonstrate the non-inferiority of ibezapolstat to vancomycin, though there can be no assurance that these early-stage, Phase 2 data will predict results in Phase 3 clinical trials.

We believe that our existing cash will not be sufficient to meet our anticipated cash requirements for at least 12 months from the issuance of our financial statements for the year ended December 31, 2023. However, our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially, including with regard to the impact of COVID-19 on our clinical trial enrollment. We have based this estimate on assumptions that may prove to be wrong, and we could deplete our capital resources sooner than we expect.

Previous wording

Compensation expense associated with stock option awards is recognized over the requisite service period based on the fair value of the option at the grant date determined based on the Black-Scholes option pricing model. Option valuation models require the input of highly subjective assumptions including the expected price volatility. Our employee stock options have characteristics significantly different from those of traded options, and changes in the subjective input assumptions can materially affect the fair value computation using the Black-Scholes option pricing model. Because there is no public market for our stock options and very little historical experience with our stock, similar public companies were used for the comparison of volatility and the dividend yield. The risk-free rate of return was derived from U.S. Treasury notes with comparable maturities. We will continue to analyze the expected stock price volatility and will adjust our Black-Scholes option pricing assumptions as appropriate. Any changes in the foregoing Black-Scholes assumptions, or if we were to elect to utilize an alternative method for valuing stock options granted to employees, officers and directors, could potentially impact our stock-based compensation expense and our results of operations.

Prior to that, we completed our Phase 2a clinical trial of ibezapolstat to treat patients with CDI and reported the top-line data in November 2020. The Phase 2a clinical trial was terminated early based upon the recommendation of our Scientific Advisory Board (the “SAB”). The SAB reviewed the study data presented by management, including adverse

Current report — wording carried from elsewhere

Ibezapolstat was well-tolerated in the Phase 2 clinical trial. In the Phase 2b segment, there were three patients each experiencing one mild adverse event assessed by the blinded investigator to be drug-related. All three events were gastrointestinal in nature and resolved without treatment. In the Phase 2a segment, there were seven adverse events reported in four patients, with only one (nausea) likely related to ibezapolstat. One severe adverse event occurred (an exacerbation of a migraine headache) but was considered to be unrelated to ibezapolstat. There were no drug-related treatment withdrawals or no drug-related serious adverse events, or other safety findings of concern in either segment of the Phase 2 clinical trial.
