Thanks, Rob. Good morning, everyone and thanks for joining us on this conference call to review our financial results for the fourth quarter and year ended 12/31/2022. And also I'll cover some recent updates and then we'd be pleased to take any questions. In the fourth quarter of 2022, we continue to enroll more patients in our Phase IIb clinical trial of ibezapolstat, our lead antibiotic candidate for the treatment of patients with C. difficile infection or CDI, as we call it. The Phase IIb clinical trial is a randomized 1:1 noninferiority double-blind trial of oral ibezapolstat compared to oral vancomycin, a standard of care to treat CDI. The primary endpoint is clinical cure at the end of treatment and a secondary endpoint is sustained clinical cure measured at day 38 follow-up visit. Since this is a double-blind trial, results won't be known until the end of the trial. However, operationally, the trial is proceeding as expected with no safety signals reported to date and the blinded observed data has been exceptional. Phase IIb trial protocol includes an exploratory endpoint comparing the impact on the microbiome between ibezapolstat and the standard of care of vancomycin. Inferiority of ibezapolstat to vanco has demonstrated further analysis will be conducted to test for superiority. As we've previously discussed, due to slower-than-expected enrollment during and possible resurgence of COVID-19 infections, we expanded the number of clinical trial sites participating in the Phase IIb trial from the initial 12 sites to a total of 28 trial sites. This project was commenced in July 2022 and completed in the fourth quarter. We remain particularly excited about the dual impact of using ibezapolstat to treat acute CDI while appropriately managing the long-term care in each patient's microbiome which we believe is exceptional for antibiotic therapy. Details of…

Thanks, Dave. Our financial results for the fourth quarter and full year ended December 31, 2022, were included in our press release issued earlier this morning. The company ended the year with cash totaling $9.1 million compared to $13 million as of December 31, 2021. Research and development expenses for the 3 months ended December 31, 2022, were $1.4 million compared to $0.7 million for the 3 months ended December 31, 2021. The increase was due to an increase in Phase IIb trial related costs. For the 12 months ended December 31, 2022, research and development expenses were $4.8 million versus $2 million for the 12 months ended December 31, 2021. The increase was due primarily to Phase IIb trial related costs. General and administrative expenses for the 3 months ended December 31, 2022, were $1.8 million compared to $1.9 million for the 3 months ended December 31, 2021. The slight decrease was primarily due to a decrease in professional fees. For the 12 months ended December 31, 2022, general and administrative expenses were $7.3 million versus $10.8 million for the 12 months ended December 31, 2021. The decrease was primarily attributable to a decrease in professional fees and stock-based compensation expense, partially offset by an increase in insurance costs. The company reported a net loss of $3.3 million or $0.28 per diluted share for the 3 months ended December 31, 2022 compared to a net loss of $2.6 million or $0.26 per diluted share for the 3 months ended December 31, 2021 and a net loss of $12.1 million or $1.12 per share for the 12 months ended December 31, 2022 compared to a net loss of $12.7 million or $1.49 per diluted share for the 12 months ended December 31, 2021, all for the reasons previously mentioned. The company had 11,627,609 shares outstanding as of December 31, 2022. With that, I'll turn the call back to Dave.

Thanks, Rob and to all of you for joining us today. We're very enthusiastic about our continuing strong fundamentals and we're especially pleased to report Acurx' progress in the fourth quarter of 2022. We look forward to building on this momentum in coming months even during these most challenging times and to update you as we do so. I'd now like to open up the call to questions. Operator?

[Operator Instructions] Our first question is from Jason McCarthy with Maxim.

When do you expect an outcome or response from FDA on the IND for the IDMC?

No problem. Thanks for joining us today, Jason. We expect in the coming days or weeks, certainly in the month of March, a response from the FDA on the amendment. But we're sure that there's going to be no issue with our -- taking the interim look at the data. This is a Phase II, not a Phase III registration trial. And there's plenty of precedent supporting it and no precedent we found that would suggest that we won't be able to take the look. So we're confident we'll be able to take the look. It is a protocol amendment. So it's, as you know, a highly technical scientific document. So we're sure to get comments whether they're substantive in nature or language -- linguistic type of comments but the overall theme of taking the interim look is something that we're certain is -- we're highly confident it's going to be just fine.

Do you think that -- will the interim look be predicated on non-inferiority? Or would you be looking for superiority kind of like you saw in the Phase IIa? And would it be reported? Would you report that data? Or would you just get a halt the trial for efficacy or just continue as planned outcome?

No. So we've always said that when we get to the end of the trial, in the end, may very well be 36 patients, well after testing for non-inferiority which is the primary endpoint, we do have an exploratory endpoint to go ahead and test for superiority as well. So that process isn't changed by taking the interim look. I think what we'll probably do is get out as soon as possible, the top line data from the IDMC when we receive it with the understanding that we'll get out another press release with a full data set down the line when the database is locked and the data is scrubbed and we get the final study report.

Just last question. With the increase in the number of trial sites have you seen, enrollment start to tick up? And if so, how long do you expect it to take to get to the 36 patients for the IDMC?

The enrollment's definitely ticked up a bit. But we're focused more -- we can get the patients all the way through the prescreening process and that it's almost a question of physiology and patient consent. So just yesterday, there was a patient that qualified out West and they just didn't want to consent to being in the trial. They changed their mind. And we can't control that. But what we can control with all of the efforts we've done with adding all these trial sites is we're seeing an average of 5 to 7 patients being prescreened every week. So the question that we ask is, how long does it take to have 5 to 7 prescreened patients per week turn into 11 enrolled patients. And the answer to that question, everyone is like a fingerprint. Everyone's going to have a different opinion but it could be a couple of months, it could be a few months. But it's certainly not a very long period of time.

And just quickly, can you just review your thoughts on what treatment guidelines could look like with an ibezapolstat getting to approval with fidaxomicin, vancomycin kind of go in the rearview mirror and they would move to whatever comes out next because ridinilazole seems to be out, right? ibezapolstat that seems to be kind of the only game in town, new antibiotic that's out there.

Yes. Well, so it will subject to the data. If the data holds the way the ibezapolstat data has been trending, the people that write the guidelines, the IDSA treatment guidelines suggest the next approved drug to treat C. diff that comes out that makes the recommendation list is going to kind of mean the twilighting of oral vancomycin similar to how metronidazole was twilighted a couple of years ago and is no longer recommended. So that's kind of where the intelligencia [ph] is in the C. diff space. You're quite right, ridinilazole didn't make it. There have been a number of things that haven't made it down the line, fecal transplant, stuff like that. But we think that we would be used frontline, fidaxomicin isn't a bad drug. It's -- in my view, it's better than oral vancomycin in a lot of ways but it's so prohibitively expensive. And with the Medicare and Medicaid reimbursement rules, it's therefore used last line. And we don't expect that to change. And remember that, that's not a QIDP drug fidaxomicin, was approved before QIDP was a law. And therefore, it wouldn't qualify for things like the DISARM Act which was put branded antibiotics on equal footing with generics so that hospitals could use the best antibiotic frontline instead of the cheapest antibiotic frontline.

Our next question is from Ed Arce with H.C. Wainwright.

This is Thomas [ph] asking a couple of questions for Ed. So first, regarding the Phase IIb study, just wondering will patient screening and enrollment continue while the interim review is ongoing?

No, I don't think it will. We'll put a pause. In other words, we won't terminate the trial. We'll put a pause on further enrollment while the evaluation is happening but we don't expect the evaluation to take a long period of time. It should take a few days, not an extensive period of time.

Right. Got it. Okay. And then another question on the Phase IIb specifically for the IDMC. Can you tell us how long is this go and the background, does it include anyone with regulatory experience?

Absolutely. It's folks in microbiology, statisticians, significant clinical development. It's quite a star-studded team. And if you'd like to find out more details about their CV information, we could certainly have an off-line conversation about that and I'm sure we can make you comfortable. It's a powerful group.

Okay, sounds good. And then perhaps one last question, the most -- you outlined the $11.3 million grants that was filed over. Is this a CARB-X grant and if not, do you give us any other details were space?

Yes. It is a CARB-X grant.

Okay, got it. Thank you so much for taking our questions and looking forward to the Phase II update.

Our next question is from James Molloy with Alliance Global Partners.

The [indiscernible] post interim look, I guess, presuming things go well and you looking it's an early stoppage for success. What's the thinking on timing for, I guess, for going forward with the non-inferiority trial or sort of the next steps post that interim look?

So after the interim look, we would promptly release top line data and then wait for the database to be locked, data scrubs, final study report and that will be then put into an FDA post-Phase II meeting package and we would meet the FDA to kind of outline and kind of negotiate what Phase III will look like. And that whole process from the time we get the final study report to the time we have the FDA's concurrence, is probably a 90-day process. And during that time period, we'll also be going out to kind of recruit more clinical trial centers, probably at least 50 or 75 trial centers to start with, just to get us off the ground for Phase III. And then Phase III would formally start sometime in the first half of 2024.

Excellent. And then maybe a bigger picture, has there been any updates on the PASTEUR Act and anything going on there that you can talk about?

Well, we signed on to a letter from dozens of members of the Antimicrobials Working Group who are in our space to Congress just about 2 weeks ago. And as we find out through our affiliation with the Antimicrobials Working Group, there are 60 U.S. senators now that approve of the content of the PASTEUR Act. So having passed the house, one would think that it is extremely close. We know that Patty Murray, the Democrat that's been leading the charge from the state of Washington is very supportive. I don't know where President Biden is on it conceptually. But I do know that there is now a budget battle in Washington. I don't know exactly how that's going to turn out, generally or specifically with regard to whether PASTEUR will be included in some component of that massive piece of legislation. So it's percolating. It was days away from being approved twice in 2022; so you just never know.

Great. And then I can remind my last question is the -- looking at OpEx here, you guys are is always good stewards of shareholder capital. Are these the sort of levels that we should anticipate OpEx being in 2023? And then for, I guess, changing pen in the Phase III starting? And what's your current sort of run rate with the $9 million in cash?

So we're spending on average about $2.2 million per quarter currently. It would certainly be nice for the CARB-X grant to be approved. And we'll find out in April, if that is approved, that will be a nice shot in the arm for us. It's about $1 a share in value non-dilutively. But -- so clearly, we have enough money to get through the end of the year. Phase III, obviously, is going to be an expensive endeavor. And our objective is let's get through the study. Let's see if we get the CARB-X grants. And we'll go from there. If we can opportunistically add a nip or a tuck here or there, capital-wise, we will, it wouldn't be anything tremendously large but at some point, we'd probably do a little something. Keep in mind, our original business plan from day 1 is to get through the Phase IIb clinical trial and explore strategic alternatives. We certainly love what we're doing in Phase III would be quite exciting. But since our job is to deliver shareholder value, we'll give it an honest look.

Thank you. There are no further questions at this time. This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation.
