Acurx Pharmaceuticals (NASDAQ:ACXP), headquartered in King of Prussia, Pennsylvania, is a clinical‐stage biopharmaceutical company focused on the discovery and development of novel anti‐infective therapies. The company’s research platform leverages insights into bacterial virulence regulation and quorum sensing pathways to design small-molecule candidates aimed at reducing pathogen toxicity and biofilm formation. By targeting key mechanisms of infection rather than bacterial viability alone, Acurx seeks to offer differentiated treatment options that may help address the growing challenge of antibiotic resistance.

Acurx’s lead product candidates are being developed to treat acute bacterial skin and skin structure infections (ABSSSI), including cases caused by drug-resistant strains such as methicillin-resistant Staphylococcus aureus (MRSA). These candidates are engineered to limit bacterial communication and toxin production, potentially enhancing host response while preserving the normal microbiome. The company advances its programs through preclinical studies with the intent to move into first-in-human trials once regulatory filings are secured.

Since its founding in the mid-2010s, Acurx has established collaborations with academic laboratories and industry partners to bolster its drug discovery efforts and accelerate preclinical development. While its operations are predominantly U.S.-based, the company aspires to serve international markets following regulatory approvals. Acurx’s management team comprises professionals with experience in infectious disease research, pharmaceutical development, and regulatory strategy, reflecting a collective commitment to addressing unmet needs in anti‐infective therapy.

Acurx Pharmaceuticals Q1 2026 Earnings Call Transcript

Key Takeaways

• Positive Sentiment: Acurx said it is starting an rCDI clinical program for ibezapolstat, beginning with a 20-patient open-label pilot, and management believes the drug could ultimately become a single-agent approach for treating acute C. difficile infection and preventing recurrence.
• Positive Sentiment: The company highlighted encouraging prior phase II data, including a 96% cure rate and no recurrences among cured patients, and said the new microbiome-sparing profile may support ibezapolstat's differentiation versus existing therapies.
• Positive Sentiment: Management pointed to the FDA's recent final guidance suggesting that, in some cases, one adequate and well-controlled trial with confirmatory evidence may be sufficient for C. difficile registration, which could potentially simplify Acurx's acute CDI development path.
• Positive Sentiment: Acurx also said the April financing, together with its equity line of credit, provides the cash resources to fund the exploratory rCDI trial, and the company ended Q1 2026 with $9.3 million in cash.
• Neutral Sentiment: First-quarter results showed a net loss of $1.7 million versus $2.1 million a year ago, with lower R&D and G&A expenses year over year. The company said it expects the rCDI trial to start up now and is targeting a first patient in August.

Presentation

[Operator]

Greetings, welcome to the Acurx Pharmaceuticals First Quarter 2026 Earnings Call. At this time, all participants are in a listen only mode. A question and answer session will follow the formal presentation. If anyone should require operator assistance during the conference, please press star zero on your telephone keypad. As a reminder, this conference is being recorded. I'd now like to turn the call over to your host, Mr. Rob Shawah, Chief Financial Officer. Please go ahead, sir.

[Rob Shawah, CFO at Acurx Pharmaceuticals]

Thank you, Melissa. Good morning, and welcome to our call. This morning, we issued a press release providing financial results and company highlights for the first quarter of 2026, which is available on our website at acurxpharma.com. Joining me today is David Luci, President and Chief Executive Officer of Acurx, who will start by providing a corporate update and outlook. Following that, I'll provide some highlights of the financial results from the first quarter ending March 31, and then turn the call over to David for his closing remarks. As a reminder, during today's call, we'll be making certain forward-looking statements which are based on current information, assumptions, estimates, and projections about future events that are subject to change and involve a number of risks and uncertainties that may cause actual results to differ materially from those contained in the forward-looking statements.

[Rob Shawah, CFO at Acurx Pharmaceuticals]

Investors should consider these risks and other information described in our filings with the Securities and Exchange Commission, including our quarter report on Form 10-Q, which we filed yesterday, Monday, May 11, 2026. You are cautioned not to place undue reliance on these forward-looking statements. Acurx disclaims any obligation to update such statements at any time in the future. This conference call contains time-sensitive information that's accurate only as of the date of this live broadcast, today, May 12, 2026. I'll now turn the call over to Dave. Dave?

[David Luci, President and CEO at Acurx Pharmaceuticals]

Thanks, Rob. Good morning, everyone, and thank you so much for joining us to review our financial results for the first quarter of 2026 and also to hear some recent updates. We'd be pleased to take any questions. For the Q&A, our Executive Chairman, Bob DeLuccia, and our Medical Director, Michael Silverman, have joined us today and will be available for those questions about our rCDI program or other matters. First, I'd like to briefly summarize just a few of our key activities for the first quarter of 2026, or in some cases, shortly thereafter. On March 9th, 2026, we issued a press release announcing that we're starting up a groundbreaking ibezapolstat clinical trial program in patients with recurrent CDI or rCDI that has the potential to shift the paradigm of treatment and prevention of recurrent C.

[David Luci, President and CEO at Acurx Pharmaceuticals]

From two agents to just one, our ibezapolstat. When coupled with ibezapolstat phase II results, which showed a 96% cure rate with no recurrent C. difficile in 25 of 25 patients who were cured, sparing the microbiome, this new trial has the potential to position ibezapolstat to be a new standard of care as the first agent to treat both acute CDI and prevent rCDI. In the acute CDI phase II trial, all 25 patients, 100% treated with ibe who experienced a clinical cure of CDI were free of recurrence one month after treatment. Very importantly, five of these patients who were observed for three months after treatment remained free of recurrence. The new clinical trial in rCDI builds on ibezapolstat's strength, namely that no patients who were cured of their infection experienced a recurrence.

[David Luci, President and CEO at Acurx Pharmaceuticals]

Clinicians and patients are avoiding the recurrence trap associated with currently available therapies. This new trial begins with an open label pilot study to gain experience with ibezapolstat in patients with multiply recurrent CDI who've had at least three episodes of CDI within the past 12 months. This will inform elements of a planned active control phase III registration trial in the rCDI indication to be implemented following favorable results from the open label 20-patient trial. Upon subsequent successful completion of the phase III pivotal rCDI trial and per the operative FDA procedure, Acurx plans to request FDA approval for treatment and prevention of rCDI under the FDA's limited population pathway for antibacterial and antifungal drugs guidance for industry. Acurx clinical program in the broader acute CDI patient population is ready to advance to phase III international pivotal clinical trials.

[David Luci, President and CEO at Acurx Pharmaceuticals]

In this regard, we're very excited about the FDA's recent announcement published in the New England Journal of Medicine that a one trial requirement will be FDA's new default standard. That is for registration. If formalized, and we can talk about that in the Q&A, this would end the long-standing two-trial dogma. We look forward to FDA's further clarification and the potentially favorable implications to our clinical development program, such as the opportunity to seek marketing approval for the acute CDI population with one pivotal clinical trial. On March 30, 2026, we announced that the Korean Intellectual Property Office granted a new patent which covers DNA polymerase IIIC inhibitors, including compositions of matter, methods of use, and pharmaceutical compositions, which further strengthen Acurx's intellectual property portfolio and represents the most recent addition to our expanding series of granted patents in the U.S. and internationally.

[David Luci, President and CEO at Acurx Pharmaceuticals]

To date, we've secured 10 patents, including five U.S. patents, along with patents in Israel, Japan, India, Australia, and Korea, all of which protect key aspects of the company's product pipeline. Significantly, a new patent was recently issued relating to ibezapolstat and its use to treat CDI while reducing recurrence of infection and improving the health of the gut microbiome. Additional country-level patent applications remain under review. In February 2026, we announced that the USPTO granted a new patent for our DNA pol IIIC inhibitors covering composition of matter and method of use. This patent extends to December 2039, subject to extension under U.S. patent rules.

[David Luci, President and CEO at Acurx Pharmaceuticals]

On April 16th, 2026, the company announced the closing of a registered direct offering of 825,085 shares of our common stock or pre-funded warrants in lieu thereof at a purchase price of $3.03 per share or pre-funded warrant in lieu thereof, priced at the market under Nasdaq rules. In addition, in a concurrent private placement, the company issued unregistered short-term warrants to purchase up to 1,650,170 shares of common stock. The short-term warrants have an exercise price of $2.78 per share and are immediately exercised upon issuance and will expire 24 months following the effective date of the registration statement registering the resale of the shares of common stock underlying the short-term warrants.

[David Luci, President and CEO at Acurx Pharmaceuticals]

That registration statement, I'm happy to say, is now effective. This additional funding, when coupled with the remaining availability under our equity line of credit, ensures that the company has the financial resource to conduct the exploratory clinical trial in recurrent C. difficile infection. Just last month, a scientific poster showing our new DNA pol IIIC systemically absorbed compounds in preclinical development to treat other Gram-positive infections achieved potentially therapeutic plasma levels and reduced MRSA tissue burden while maintaining a high gut microbial diversity similar to baseline and distinct from linezolid. This poster was presented at the 35th Congress of ESCMID Global, the European Society of Clinical Microbiology and Infectious Diseases Annual Scientific Conference, held in Munich, Germany from April 17 to April 21.

[David Luci, President and CEO at Acurx Pharmaceuticals]

Dr. Khurshida Begum, research scientist, University of Houston College of Pharmacy, presented the poster entitled Preclinical Microbiome Evaluation of Novel DNA pol IIIC Inhibitor Compounds. Using microbiome profiling metagenomics, the authors concluded that DNA pol IIIC compounds represent a targeted strategy to treat resistant Gram-positive infections while preserving the microbiome structure, minimizing downstream complications associated with antibiotic-induced dysbiosis. We continue to identify and pursue funding opportunities for our phase III clinical trial program for ibezapolstat and acute CDI. We have several initiatives underway to this end and will report results in future updates. As we've continually reported, ibez clinical and non-clinical results continue to outperform in a series of potentially life-threatening infectious disease caused by C. difficile bacteria that the CDC categorizes as an urgent threat and calls for new classes of antibiotics for initial treatment and also have a low incidence of recurrence.

[David Luci, President and CEO at Acurx Pharmaceuticals]

Ibezapolstat has FDA QIDP and Fast Track designations for treatment of CDI, as well as in Europe, small and medium enterprise or SME status. All Acurx compounds in preclinical development are eligible for QIDP and Fast Track designation, and they target Gram-positive infections classified as serious threat priorities by the CDC. We remain confident that while development of ibezapolstat's competitive profile continues to evolve and strengthen, we'll continue to navigate successfully through these challenging times in the macroeconomic environment in our industry sector. Back to our CFO, Rob Shawah, to guide you through the highlights of our financial results for the first quarter of 2026. Rob.

[Rob Shawah, CFO at Acurx Pharmaceuticals]

Thanks, Dave. Our financial results for the first quarter ended March 31, 2026, were included in our press release issued earlier this morning. The company ended the quarter with cash totaling $9.3 million compared to $7.6 million as of December 31, 2025. During the quarter, the company raised a total of approximately $3.1 million of gross proceeds through purchases under its equity line of credit. Research and development expenses for the three months ended March 31, 2026, were $0.3 million. Compared to $0.6 million for the three months ended March 31, 2025, a decrease of $0.3 million.

[Rob Shawah, CFO at Acurx Pharmaceuticals]

The decrease was primarily due to a decrease in manufacturing costs of $0.1 million and a decrease in consulting related costs of $0.2 million as a result of prior year trial preparation related expenses. General and administrative expenses for the three months ended March 31, 2026 were $1.4 million. That was compared to $1.6 million for the three months ended March 31, 2025, a decrease of $0.2 million. The decrease was primarily due to a $0.1 million decrease in professional fees and a $0.1 million decrease in legal costs. The company reported a net loss of $1.7 million or $0.62 per diluted share for the three months ended March 31, 2026.

[Rob Shawah, CFO at Acurx Pharmaceuticals]

That was compared to a net loss of $2.1 million or $2.15 per diluted share for the three months ended March 31, 2025, all for the reasons previously mentioned. The company had 3,389,106 shares outstanding as of March 31, 2026. With that, I'll turn the call back over to Dave. Dave?

[David Luci, President and CEO at Acurx Pharmaceuticals]

Thanks. Thanks, Rob, and to all of you for joining us today. Before bringing our operator, Melissa, back to open the call for questions, I'm pleased to introduce to our call Dr. Michael Silverman, our Medical Director, and Bob DeLuccia, our Executive Chairman, to assist with Q&A regarding our rCDI program or any other matters of an R&D nature. Bob and Michael can also respond to questions regarding the recent FDA guidelines for pivotal phase III trials in C. difficile. Now I'd like to turn the call over to our operator, Melissa, to open the call for any questions. Melissa?

[Operator]

Thank you. If you like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you'd like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star key. Our first question comes from the line of James Molloy with Alliance Global Partners. Please proceed with your question.

[James Molloy, Managing Director and Senior Biotechnology & Specialty Pharmaceuticals Analyst at Alliance Global Partners]

Hi, guys. I just take my questions. I'd love to walk through the new guidance. You mentioned, you know, if this gets formalized with the one trial, only the one trial needed. Can you walk through what the steps are to actually formalize that? How confident are you that this will be, or at least that the recurrent CDI or the phase III CDI trial might fit underneath this rubric of

[David Luci, President and CEO at Acurx Pharmaceuticals]

Well, let me start out just by saying, before I turn it over to Bob and Mike, we believe this is it's formalized as far as the FDA is concerned. It came out as formal guidance Friday night of last week. Now, whether or not it can be formalized in, you know, kind of our lineage of regulatory interaction with the FDA as it applies to ibezapolstat, that's, I think, the question that we have to answer with the FDA. Thankfully, we have a meeting scheduled to address that Bob and Mike can talk about. Bob, would you like to-

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Yeah.

[David Luci, President and CEO at Acurx Pharmaceuticals]

Add to that?

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Sure. Well, thanks, Dave, and thanks, James, for the question. Yeah, we're still going through this in detail. As Dave said, it just came out Friday night. At first pass, we don't see anything that will require a change in our pivotal trial design, which is already agreed to with the FDA. However, we're very excited to see that this new guidance explicitly states, and it now formalizes what had been published previously in the New England Journal of Medicine, but now specifically for C. difficile infection, in that it may be possible to rely on one adequate and well-controlled trial with confirmatory evidence to meet the substantial evidence of effectiveness standards. We've scheduled a meeting, as Dave said, to discuss this with the FDA.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

You know, Mike, maybe you can expand a little bit on what FDA considers as confirmatory evidence, which we think strengthens our position with the FDA. Mike?

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Sure, Bob. Thank you. Thank you for that. Do you hear me all right?

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Yep.

[James Molloy, Managing Director and Senior Biotechnology & Specialty Pharmaceuticals Analyst at Alliance Global Partners]

Yes.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Yep, the line's good. Okay, thanks for the question. I just want to emphasize something David Luci and Robert DeLuccia said about the formalization, if you will. This new guidance refers back to a lineage of other FDA guidances going back to at least 2019, discussing the feasibility and the requirements for a single trial. What is very important is the new guidance, which is a final guidance, it's not a draft guidance, applies it specifically to C. difficile. As Bob said, that's one of the things that helps to strengthen our position. The theme that runs through all the guidances that we're discussing is that a single trial needs to be supported by what FDA considers to be, more or less quoting, substantial, I'm sorry, confirmatory evidence of substantial efficacy.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

By confirmatory evidence, they have a number of criteria, a number of categories of other evidence besides the phase III trial. That would contribute. We actually tick a few of those boxes, which again, helps us strengthen our position. One is mechanistic data, okay? In anti-infectives, that is something that we can demonstrate in a straightforward fashion because we have our activity in the test tube, our in vitro data, our MICs or killing data for the bacteria. We also have in vitro test tube data showing anti-virulence activity of our drug, and we have animal efficacy data in the model that is considered to be the standard, and has predicted efficacy of other drugs on the market.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

We know a great deal about the mechanism of action down to the molecular, in fact, the atomic level, which will also support our case. We have microbiome data that Dave referred to, which is another mechanistic aspect that helps build the case for not just treatment efficacy, but reduction of recurrence. Circling back to put that all together, the animal model, again, pulls all these factors together and demonstrates the activity. That is our position of confirmatory evidence of substantial efficacy.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Great. Thanks, Mike. James, does that answer your question?

[James Molloy, Managing Director and Senior Biotechnology & Specialty Pharmaceuticals Analyst at Alliance Global Partners]

That does. Thank you very much. I guess my last question would be on the phase label you suggest there might be an interim look at 10. You're gonna have 20 people in the trial's expectation. What's sort of the ideal you would like to get from this open label trial to serve for the design of the phase III hopefully the single phase III trial? Maybe a quick clarification too. You know throughout the call you talk about acute CDI recurrent CDI. How do those differ materially from sort of regular CDI? I guess recurrent obviously it's recurring but treating the three at the end of the day, it's still sort of the same treatment, correct?

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Yeah. Mike, go ahead. You know, you can clarify

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Yeah.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Between the phase III trials.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Sure.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Yep.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Sure. Sure, James. A couple of different aspects of your questions. One is that the 20-patient trial we're doing is in a population with multiple recurrences. That's different than the phase III trial we've been talking about as a potential single pivotal trial, which is in patients who've had a single episode or no more than one recurrence. Okay? You're absolutely right that when a patient gets an acute episode of C. diff infection, the patient requires antibiotic treatment. Okay? That's for the acute episode. Generally, it's 10 days, at least that's the standard for the drugs that are approved now. That's 10 days of treatment to cure the acute episode. The problem is that, depending on what you read and what drugs you use, 20% or 30% of those patients will have at least one recurrence.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

The recurrence is because the initial infection sets up conditions to allow C. diff to recur. The interesting thing about the new guidance is that for the first time, it talks about not just treatment and prevention of recurrence, it talks about long-term prevention of disease in a prophylactic fashion. The opportunities for studying patients for short-term cure, for kind of intermediate or let's say one-month reduction of recurrence, and then for longer-term follow-up for even further reduction of recurrence have actually grown. We still will be treating people acutely, all right? Then we observe after that for rates of recurrence. I'm not sure if that answers all your questions.

[David Luci, President and CEO at Acurx Pharmaceuticals]

Well.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

That.

[David Luci, President and CEO at Acurx Pharmaceuticals]

Just to add to that, there there's two separate pathways. you can think of it, James, like we have kinda two potential shots on goal. there's the phase III pathway in what we call acute CDI, which is currently two phase III registration trials that may now become one trial. there's a separate pathway under the LPAD, guidance, for recurrency that's starting with an exploratory 20-patient phase II, look at the data, and then we would do, hopefully, one trial for phase III, if the FDA agrees we have LPAD designation, and then we can get approval in that sense. there's two separate pathways to FDA approval.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

That's rCDI, Dave. You're right. To separate-

[David Luci, President and CEO at Acurx Pharmaceuticals]

Yeah.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

The two. Right. Okay, Jim?

[James Molloy, Managing Director and Senior Biotechnology & Specialty Pharmaceuticals Analyst at Alliance Global Partners]

Excellent. Thank you for taking my questions.

[David Luci, President and CEO at Acurx Pharmaceuticals]

Thank you, Jim.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

You're welcome.

[Operator]

Thank you. Our next question comes from the line of Jason McCarthy with Maxim Group. Please proceed with your question.

[Jason McCarthy, Senior Managing Director and Head of Biotechnology at Maxim Group]

Hi, guys. Thank you for taking the question. Can you talk a little bit about, and you mentioned it briefly, the importance of the microbiome alterations or rather preservation of the good bacteria, how much emphasis there was in the new guidance related to that, and how you plan to present your microbiome data when you meet with FDA this summer, to talk about kind of, I guess, the parameters of the phase III?

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Yeah. Thank you, Jason. That's a great question. Mike, you can expand a little bit on that, on microbiome with the work of Kevin Gary at Houston.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Yeah, agreed. That is a great question. Microbiome, the microbiome assessment is key to our program, but it's important to understand that this is not something that would be considered for an approvable claim, not something that would initially get us approval or perhaps even end up in the label. Right now, it's an ancillary marker, an exploratory marker, because it is not something that the patient experiences. However, the microbiome is critically important in treatment and reduction of recurrence in C. diff. When a C. diff, C. difficile infection occurs, an antibiotic is given, there is tremendous alteration of the bacteria which normally live in the gut, the microbiome.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

The balance of those bacteria change such that metabolism in the gut changes, particularly the metabolism of bile acids. Certain bile acids are critical in actually suppressing the growth of C. difficile. When you give an antibiotic like vancomycin and the bacteria that create those beneficial metabolites are gone. You don't have those metabolites that suppress C. difficile. That is one of the key aspects in leading to recurrent disease, the absence of good bacteria and the good metabolites to suppress C. diff. We've seen through our work, as Bob said, with Dr. Garey at University of Houston, that ibezapolstat, and in fact, other compounds in the same series that Dave mentioned are much gentler on the microbiome, do not lead to the eradication of the quote good bacteria, like a drug such as vancomycin would do.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

those bacteria that are producing the bile acids that suppress the growth of C. difficile are maintained, and we believe that's a main feature in reducing recurrence. Again, that's not something that would get us approval, but it's part of the pharmacology of the drug that we think we can leverage.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Thank you, Mike. Yeah.

[Jason McCarthy, Senior Managing Director and Head of Biotechnology at Maxim Group]

Great. Thank you. Also, when you're thinking about, I guess, the parameters for the phase III, and you're talking about your data with FDA this summer, would the recurrence measure or reduced recurrence measure be it's that standard 30 days? Would you go out further, even if exploratory, because you had those five people that went out, I think it was 90+ days, that had no recurrence? all of that with, are you gonna have to go head-to-head with vancomycin or fidaxomicin?

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Great question. Again, you're absolutely spot on this one. The standard that you'll see for the drugs that are approved and in the studies that have been done is following the patients for one month after the completion of treatment, to assess reduction of recurrence. fidaxomicin does have some raw numbers in its label, but it does not have a claim for reduction of recurrence, and that's a long story behind that. Right now, that's the current standard. We intend to follow patients as we did in phase II. We intend to follow them in phase III for that kinda one-month standard. You're again, spot on, we are gonna follow them out to an additional month, to assess for recurrence.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

The reason that we've chosen that number is because there are two agents out there that are approved for reduction of recurrence, and their label has the claim for eight weeks following acute treatment. We will be following patients for essentially two months after the initial treatment to assess for recurrence.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Great. Thank you, Mike. That's an important distinction, and it's gonna give us a specific advantage. Thanks for the question, for sure.

[Jason McCarthy, Senior Managing Director and Head of Biotechnology at Maxim Group]

I'm sorry, those two drugs are which that have the eight-week claim?

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Oh, yeah. These are in the category that's called live biological products. They're essentially, human-made fecal microbiome transplant surrogates. One is VOWST, V-O-W-S-T, and one is REBYOTA, R-E-B-Y-O-T-A. They're both, live bacteria, which are administered to try to restore the normal microbiome balance in the gut.

[Jason McCarthy, Senior Managing Director and Head of Biotechnology at Maxim Group]

Got it. Thank you. Thanks for taking the questions, guys.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Thank you.

[Operator]

Thank you. Once again, as a reminder, if you'd like to join the question queue, please press star one on your telephone keypad. Our next question comes from the line of Matthew Keller with H.C. Wainwright. Please proceed with your question.

[Matthew Keller, VP of Equity Research at H.C. Wainwright]

Hey, good morning, everyone. Thanks for the update and for taking our question. Just quickly, you know, the FDA guidance also mentions or, like, emphasizes thoughtful selection of patient populations, especially when it comes to elderly populations. I was wondering if maybe you could talk to us about how your protocols also might align with this part of the guidance, this guidance as well.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Michael Silverman here again. Good question. We're sensitive to that, we've actually expanded our population relative to phase II to include essentially all ages. This also gets to the notion of a single trial because one of the items that supports single trial for approval is having diversity of your sites, diversity of your patient population, consistency across various subgroups. The types of subgroups we can actually obtain are not all that varied. Okay. We do have the age. We will have geographic diversity. We assume we'll have racial and ethnic diversity. The only other real factor that enters in here is whether it's a first occurrence or whether it's a first recurrence.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Other than that, the disease is relatively homogeneous, but we are sensitive to the notion of different segments of the population and the need to show consistency across all the segments. I hope that helps.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Yeah.

[Matthew Keller, VP of Equity Research at H.C. Wainwright]

Yeah. Yeah, absolutely. Also kind of changing subjects a little bit, but just more housekeeping. When can we expect the start of the rCDI trial?

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Well, we're actually

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Go ahead, Bob.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Yeah, no. We're actually in startup mode right now, as we are, contacting, sites, the planned number of sites, and we're interacting with those sites for site qualification visits right now. We're actually in a startup mode. We hope to see a first patient in, I would say probably August timeframe. Hopefully we can beat that if we can accelerate it.

[Matthew Keller, VP of Equity Research at H.C. Wainwright]

Yep. Perfect. Makes sense. Thanks again for taking my questions.

[Michael Silverman, Medical Director at Acurx Pharmaceuticals]

Thank you.

[Bob DeLuccia, Executive Chairman at Acurx Pharmaceuticals]

Thank you, Matt.
