STATEN ISLAND, N.Y., March 18, 2024 /PRNewswire/ -- Acurx Pharmaceuticals, Inc. (NASDAQ: ACXP) ("we" or "Acurx" or the "Company"), a clinical stage biopharmaceutical company developing a new class of antibiotics for difficult-to-treat bacterial infections, announced today certain financial and operational results for the fourth quarter and full year ended December 31, 2023. Highlights of the fourth quarter ended December 31, 2023, or in some cases shortly thereafter, include: In October 2023, we ended enrollment in our Phase 2b clinical trial of ibezapolstat, our lead antibiotic candidate, for the treatment of patients with C. difficile infection, or CDI. In November 2023, we reported top-line data from the Phase 2b clinical trial, including overall results from the full Phase 2 study, demonstrating an ibezapolstat clinical cure rate at end of 10-days' oral treatment, or EOT, of 96% (25 of 26 patients) which included 100% cure in Phase 2a (10 of 10 patients) and 94% in Phase 2b (15 of 16 patients) compared with the vancomycin control arm of 100% (14 of 14 patients) at EOT. No safety concerns were reported in either arm of the Phase 2b clinical trial and ibezapolstat was well tolerated in all patients in both the Phase 2a open label trial and in the Phase 2b vancomycin-controlled segment. In consultation with its scientific advisors, the Company determined that based on review of aggregate blinded data the Phase 2b vancomycin-controlled trial segment was terminated early due to success showing high observed clinical cure rates with no emerging safety concerns. We also stated at that further data would be provided as they become available on secondary and exploratory endpoints from the Phase 2b trial segment, including sustained clinical cure data at 30 days after EOT, and Extended Clinical cure data up to 94 days as well as comparative data on the impact to the patient's microbiome. In December 2023, we announced the sustained clinical cure data. These data showed that in the Phase 2b clinical trial segment 100% or 15 out of 15 patients who were cured at EOT remained cured with no reinfection 30 days later while vancomycin experienced a reinfection rate of 14.3% (2 of 14 patients). In January 2024, the Company announced positive comparative microbiology and microbiome data for ibezapolstat in CDI patients from the Phase 2b clinical trial segment. Ibezapolstat outperformed vancomycin showing eradication of fecal C. difficile at Day 3 of treatment in 15 of 16 treated patients (94%), versus vancomycin which had eradication of C. difficile in 10 of 14 treated patients (71%). Additional data from this Phase 2b clinical trial showed ibezapolstat, but not vancomycin, consistently preserved and allowed regrowth of key gut bacterial species believed to confer health benefits including to prevent recurrence of CDI. The Company anticipates that additional data from the secondary and exploratory endpoints will provide further favorable separation between these two therapeutic options in our Phase 3 clinical trial program and ultimately in the marketplace, if approved. Additional analyses regarding other secondary and exploratory endpoints will be forthcoming as data become available. Having robust preclinical, clinical and manufacturing data-to-date, the Company submitted a formidable Information Package to FDA in February 2024 along with a Request for an End of Phase 2 Meeting which was granted by the FDA and is scheduled to occur in April. We anticipate discussing our Phase 3 clinical trial mandate at this meeting and would anticipate documented meeting minutes from FDA in the second quarter of 2024. The European Medicines Agency (or EMA) approved our application to be designated as a small to medium sized enterprise (or SME) in Europe in February 2024 which provides for certain benefits including fee reductions and other support from the EMA for seeking a Marketing Authorization for Europe. In October 2023, Dr. Kevin Garey presented on behalf of the Company at ID Week with selective spectrum of activity data from our Phase 2a clinical trial. Dr. Garey is Professor and Chair, University of Houston College of Pharmacy, and the Principal Investigator for microbiome aspects of our ibezapolstat clinical trial program. Also at ID Week, Bob DeLuccia, our Executive Chairman, presented our new class of novel DNA pol IIIC inhibitors in our pre-clinical pipeline at the symposium entitled, "New Antimicrobials in the Pipeline." In November 2023, the Company filed an amendment to its shelf registration statement with the SEC and launched a $17 million at-the-market equity offering program (or ATM), with Alliance Global Partners acting as sales agent to the Company. Proceeds from the ATM have been and, in the future, are expect to be used for general corporate purposes going forward including our planned Phase 3 clinical trial mandate. Fourth Quarter and Full Year 2023 Financial Results Cash Position: The Company ended the year with cash totaling $7.5 million, compared to $9.1 million as of December 31, 2022. Subsequent to year-end, the Company sold an additional 1,121,793 shares under its ATM financing program, with gross proceeds of approximately $4.5 million. R&D Expenses: Research and development expenses for the three months ended December 31, 2023 were $1.9 million compared to $1.4 million for the three months ended December 31, 2022. The increase was due to the timing of Phase 2b trial related costs and an increase in consulting costs. For the year ended December 31, 2023, research and development expenses were $6.0 million versus $4.8 million for the year ended December 31, 2022. The increase is due primarily to Phase 2b trial-related costs and an increase in consulting costs. G&A Expenses: General and administrative expenses for the three months ended December 31, 2023 were $3.2 million compared to $1.8 million for the three months ended December 31, 2022. The increase was due primarily to a $0.8 million increase in professional fees, a $0.1 million increase in share-based compensation, and a $0.3 million increase in employee compensation costs. For the year ended December 31, 2023, general and administrative expenses were $8.5 million versus $7.3 million for the year ended December 31, 2022. The amounts reflect an increase in professional fees of $0.5 million, an increase of $0.3 million in share-based compensation, and an increase of $0.3 million in employee compensation costs. Net Income/Loss: The Company reported a net loss of $5.1 million or $0.37 per diluted share for the three months ended December 31, 2023 compared to a net loss of $3.3 million or $0.28 per diluted share for the three months ended December 31, 2022, and a net loss of $14.6 million or $1.15 per share for the year ended December 31, 2023, compared to a net loss of $12.1 million or $1.12 per diluted share for the year ended December 31, 2022 for the reasons previously mentioned. The Company had 14,468,229 shares outstanding as of December 31, 2023. Conference Call As previously announced, David P. Luci, President and Chief Executive Officer, and Robert G. Shawah, Chief Financial Officer, will host a conference call to discuss the results and provide a business update as follows: About Ibezapolstat Ibezapolstat is the Company's lead antibiotic candidate advancing to international Phase 3 clinical trials to treat patients with C. difficile Infection (CDI).

As previously announced, planning is underway with FDA to advance ibezapolstat into international Phase 3 clinical trials for treatment of C. difficile Infection (CDI) As anticipated, an End of Phase 2 Meeting (EOP2) with FDA is now confirmed to occur in late April 2024 to finalize the Phase 3 development plan Per FDA Guidance, Acurx also announced it has submitted the required pre-meeting Briefing Document to FDA yesterday, February 26, 2024 SME (Small and Medium-sized Enterprise) designation has been granted by the EMA (European Medicines Agency) which allows Acurx to benefit from fee incentives and other support from the EMA for EU Marketing Authorization Ibezapolstat has previously received FDA QIDP and Fast-Track Designation STATEN ISLAND, N.Y., Feb. 27, 2024 /PRNewswire/ -- Acurx Pharmaceuticals, Inc. (NASDAQ: ACXP) ("Acurx" or the "Company"), a late-stage biopharmaceutical company developing a new class of small molecule antibiotics for difficult-to-treat bacterial infections, today announced that an EOP2 meeting has been granted by FDA to discuss the overall Phase 3 clinical and non-clinical development plan to support an NDA (New Drug Application) filing for ibezapolstat for the treatment of CDI. The Company submitted its Meeting Request earlier this month following successful completion of ibezapolstat's Phase 2 clinical trial. On February 14, 2024, the FDA granted an EOP2 meeting which confirms adequate information was provided to warrant this type of meeting. In accordance with FDA Guidance (September 2023, REV1), the Company submitted its pre-meeting information Meeting Package (or Briefing Document) yesterday, February 26, 2024, which includes detailed information on the clinical development plan, including clinical pharmacology and clinical microbiology studies, to support the NDA filing, study design and statistical analysis plan for the Phase 3 studies. Additionally, the Company was granted SME designation by the European Medicines Agency on February 15, 2024 which allows Acurx to benefit from fee incentives and other support from the EMA for conduct of required clinical trials for ultimate EU Marketing Authorization. The SME designation was established by EMA to promote innovation and the development of new medicinal products by smaller companies. Companies with SME status are eligible to receive financial incentives as well as administrative and regulatory support through national and regional level programs. These benefits include access to dedicated EMA personnel during the clinical development process as well as reductions in fees associated with regulatory procedures such as Scientific Advice, Marketing Authorizations, and inspections. Robert J. DeLuccia, Executive Chairman of Acurx, stated: "We are very pleased to have our FDA EOP2 Meeting granted which confirms that our Meeting Request information package was acceptable since FDA could deny such a meeting for sponsors if it is premature for the stage of development or because the meeting information package provided is not adequate. He further stated: "Having SME status granted by EMA will allow us to leverage the outcome our EOP2 FDA meeting to seek EMA guidance for requirements of a Marketing Authorization in the EU which is consistent with our plan to conduct international Phase 3 clinical trials." David P. Luci, President & CEO of Acurx, stated: "We are pleased to have the opportunity to meet with FDA to confirm readiness for, and design of, our Phase 3 program which includes international clinical study sites and to have SME designation, allowing us to benefit from financial incentives and support from the EMA as we aim to ultimately bring ibezapolstat to the global pharmaceutical marketplace. Throughout 2024 we anticipate further regulatory developments internationally to leverage our success with U.S. clinical trials to date." About the Ibezapolstat Phase 2 Clinical Trial The completed multicenter, open-label single-arm segment (Phase 2a) study was followed by a double-blind, randomized, active-controlled, non-inferiority, segment (Phase 2b) at 28 US clinical trial sites which together comprise the Phase 2 clinical trial. (see ). This Phase 2 clinical trial was designed to evaluate the clinical efficacy of ibezapolstat in the treatment of CDI including pharmacokinetics and microbiome changes from baseline and continue to test for anti-recurrence microbiome properties seen in the Phase 2a trial, including the treatment- related changes in alpha diversity and bacterial abundance and effects on bile acid metabolism. The completed Phase 2a segment of this trial was an open label cohort of up to 20 subjects from study centers in the United States. In this cohort, 10 patients with diarrhea caused by C. difficile were treated with ibezapolstat 450 mg orally, twice daily for 10 days. All patients were followed for recurrence for 28± 2 days. Per protocol, after 10 patients of the projected 20 Phase 2a patients completed treatment (100% cured infection at End of Treatment), the Trial Oversight Committee assessed the safety and tolerability and made its recommendation regarding early termination of the Phase 2a study and advancement to the Ph2b segment. The Company's Scientific Advisory Board concurred with this recommendation. In the now completed Phase 2b trial segment, 32 patients with CDI were enrolled and randomized in a 1:1 ratio to either ibezapolstat 450 mg every 12 hours or vancomycin 125 mg orally every 6 hours, in each case, for 10 days and followed for 28 ± 2 days following the end of treatment for recurrence of CDI. The two treatments were identical in appearance, dosing times, and number of capsules administered to maintain the blind. The Company previously reported that 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. The Company is confident 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 segment was discontinued due to success. The Company made this decision in consultation with its medical and scientific advisors and statisticians based on observed aggregate blinded data and other factors, including the cost to maintain clinical trial sites and slow enrollment due to COVID-19 and its aftermath. The Company had determined that the trial performed as anticipated for both treatments, ibezapolstat and the control antibiotic vancomycin (a standard of care to treat patients with CDI), with high rates of clinical cure observed across the trial without any emerging safety concerns. Accordingly, an Independent Data Monitoring Committee was not required to perform an interim analysis of this Phase 2b trial data as originally planned. The Company anticipated that this decision would allow the Company to advance this first-in-class, FDA QIDP/Fast Track-designated antibiotic product candidate to Phase 3 clinical trials more expeditiously. The Phase 2b trial was originally designed to be a non-inferiority (NI) trial and later amended to include an interim efficacy analysis with review by an Independent Data Monitoring Committee (IDMC). The decision to end the trial early based on blinded clinical observations obviated the need for an interim analysis, IDMC review, and NI assessment. The Company determined, in consultation with its clinical and statistical experts, that presenting clinical cure rates for the primary efficacy endpoint is the most appropriate representation for the clinical activity of ibezapolstat in treating CDI. In the Phase 2 clinical trial, the Company will also evaluate pharmacokinetics (PK) and microbiome changes and test for anti-recurrence microbiome properties, including the change from baseline in alpha diversity and bacterial abundance, especially overgrowth of healthy gut microbiota Actinobacteria and Firmicute phylum species during and after therapy. Phase 2a data demonstrated complete eradication of colonic C. difficile by day three of treatment with ibezapolstat as well as the observed overgrowth of healthy gut microbiota, Actinobacteria and Firmicute phyla species, during and after therapy. Very importantly, emerging data show an increased concentration of secondary bile acids during and following ibezapolstat therapy which is known to correlate with colonization resistance against C. difficile. A decrease in primary bile acids and the favorable increase in the ratio of secondary-to-primary bile acids suggest that ibezapolstat may reduce the likelihood of CDI recurrence when compared to vancomycin. The company also recently reported positive extended clinical cure (ECC) data for ibezapolstat (IBZ), its lead antibiotic candidate, from the Company's recently completed Phase 2b clinical trial in patients with CDI. This exploratory endpoint showed that 12 patients who agreed to be followed up to three months following Clinical Cure of their infection, 5 of 5 IBZ patients experienced no recurrence of infection. In the vancomycin control arm of the trial, 7 of 7 patients experienced no recurrence of infection. ECC success is defined as a clinical cure at the TOC visit (i.e., at least 48 hours post EOT) and no recurrence of CDI within the 56 ± 2 days post EOT (ECC56) and 84 ± 2 days post EOT (ECC84) in patients who consented to extended observation. In the Phase 2b trial, 100% (5 of 5) of ibezapolstat-treated patients who agreed to observation for up to three months following Clinical Cure of CDI experienced no recurrence of infection. About Ibezapolstat Ibezapolstat is a novel, orally administered antibiotic being developed as a Gram-Positive Selective Spectrum (GPSS™) antibacterial. It is the first of a new class of DNA polymerase IIIC inhibitors under development by Acurx to treat bacterial infections. Ibezapolstat's unique spectrum of activity, which includes C. difficile but spares other Firmicutes and the important Actinobacteria phyla, appears to contribute to the maintenance of a healthy gut microbiome. In June 2018, ibezapolstat was designated by the U.S. Food and Drug Administration (FDA) as a Qualified Infectious Disease Product (QIDP) for the treatment of patients with CDI and will be eligible to benefit from the incentives for the development of new antibiotics established under the Generating New Antibiotic Incentives Now (GAIN) Act. In January 2019, FDA granted "Fast Track" designation to ibezapolstat for the treatment of patients with CDI. The CDC has designated C. difficile as an urgent threat highlighting the need for new antibiotics to treat CDI. About Clostridioides difficile Infection (CDI). According to the 2017 Update (published February 2018) of the Clinical Practice Guidelines for C. difficile Infection by the Infectious Diseases Society of America (IDSA) and Society or Healthcare Epidemiology of America (SHEA), CDI remains a significant medical problem in hospitals, in long-term care facilities and in the community. C. difficile is one of the most common causes of health care- associated infections in U.S. hospitals (Lessa, et al, 2015, New England Journal of Medicine). Recent estimates suggest C. difficile approaches 500,000 infections annually in the U.S. and is associated with approximately 20,000 deaths annually. (Guh, 2020, New England Journal of Medicine). Based on internal estimates, the recurrence rate for the antibiotics currently used to treat CDI is between 20% and 40% among approximately 150,000 patients treated. We believe the annual incidence of CDI in the U.S. approaches 600,000 infections and a mortality rate of approximately 9.3%. About the Microbiome in C. difficile Infection (CDI) and Bile Acid Metabolism C. difficile can be a normal component of the healthy gut microbiome, but when the microbiome is thrown out of balance, the C. difficile can thrive and cause an infection. After colonization with C. difficile, the organism produces and releases the main virulence factors, the two large clostridial toxins A (TcdA) and B (TcdB). (Kachrimanidou, Microorganisms 2020, 8, 200; doi:10.3390/microorganisms8020200.) TcdA and TcdB are exotoxins that bind to human intestinal epithelial cells and are responsible for inflammation, fluid and mucous secretion, as well as damage to the intestinal mucosa. Bile acids perform many functional roles in the GI tract, with one of the most important being maintenance of a healthy microbiome by inhibiting C. difficile growth. Primary bile acids, which are secreted by the liver into the intestines, promote germination of C. difficile spores and thereby increase the risk of recurrent CDI after successful treatment of an initial episode. On the other hand, secondary bile acids, which are produced by normal gut microbiota through metabolism of primary bile acids, do not induce C. difficile sporulation and therefore protect against recurrent disease. Since ibezapolstat treatment leads to minimal disruption of the gut microbiome, bacterial production of secondary bile acids continues which may contribute to an anti-recurrence effect. Beneficial effects of bile acids include a decrease in primary bile acids and an increase in secondary bile acids in patients with CDI, which was observed in the Company's Ph2a trial results and previously reported (CID, 2022).
