Thank you, Vivian, and good morning, everyone. Welcome to Nuwellis Fourth Quarter and Full Year 2023 Earnings Conference Call. As Vivian mentioned, I'm currently in Boston attending the Technology and Heart Failure Therapeutics Conference, also known as THT. This conference provides attendees and look into the latest heart failure innovations, focusing on device and technology-based treatment for heart failure. This has been a productive meeting for us with much to report. Last night, we hosted a well-attended symposium, title, Aquapheresis: New Technological and Clinical Developments, where 4 of our key opinion leaders presented 3 separate significant clinical evidence findings on the safety and efficacy of the Aquadex therapy. Dr. Jefferies will provide more detail later on this call on this symposium. Yesterday, we had on podium presentation showing a statistical significance in several endpoints at 30 days, including fewer patients rehospitalized fewer days in the hospital due to heart failure readmissions, lower rehospitalization rates due to cardiovascular events fewer rehospitalization days due to cardiovascular events and fewer patients rehospitalization for cardiovascular events. More detail on this data will be presented tomorrow in a late-breaking clinical trial presentation. This conference has served as a platform for the clinical reestablishment of the superiority of ultrafiltration using Nuwellis Aquadex technology as compared to the traditional diuretics. I'm happy to open our call today with an emphasis on how excited we are about the future of Nuwellis despite the difficult environment for micro-cap companies like Nuwellis. With our steadfast focus on executing on our strategic growth initiatives, positive momentum in our business continues to build. 2024 is poised to be another important year for us with key value milestones targeted. This includes continued commercial introduction of our strategic collaborator, SeaStar Medical with their selective ciophereutic device branded coalmine. For pediatric -- for treatment of…

Thank you, Nestor, and good morning, everyone. We are pleased to continue to expand our clinical evidence, including a symposium yesterday at THT on the clinical merits of Aquadex for a growing number of patients. THT is a conference attended by heart failure specialists who are looking for innovative med tech solutions. The presentations at the symposium last night highlighted 3 important topics including the role of ultrafiltration in the treatment of acute decompensated heart failure, a clinical comparison of ultrafiltration and diuretics using the data from a 224 patient trial called AVOID-HF and the ultrafiltration best practice from a high-volume center. These 3 presentations further reinforced the efficacy of ultrafiltration reestablishing Aquadex as the preferred method of treating congestion in patients with fluid overload resistant to diuretics. Of the recent clinical publications that featured the benefits of our Aquadex therapy, let me highlight the new case series featured in clinical transplantation, which demonstrated the potential of Aquadex to safely and effectively remove fluid volume for end-stage liver disease patients who do not respond to diuretics. Of note, the findings present a new clinical application for Aquadex already within its current FDA labeling and adds a new patient population for treatment. The publication is a single-center retrospective case series that assessed the utilization of aquapheresis therapy with Aquadex in the intensive care unit setting at Mount Sinai Hospital between January 2020 and July 2023. 14 severely ill patients with end-stage liver disease were treated with the Aquadex system during this period. For clinicians treating patients with end-stage liver disease, it can be an enormous challenge to remove fluid when patients don't respond or can't tolerate diuretic therapy safely and effectively. This study demonstrates a new application for the Aquadex system for a large and growing patient population with end-stage liver disease. Unlike continuous renal replacement therapies, Aquadex allows for slow, controlled and predictable fluid removal that can be to reduce the risk of kidney injury and help alleviate the hepatorenal syndrome. Additionally, treatment with Aquadex may help patients participate in physical therapy and help better prepare them for subsequent surgery and liver transplantation. Let me turn it back over to Nestor. Thank you.

Thank you, Dr. Jefferies. I'd like to now return the call to discuss our Q4 financial results, and I'm going to turn it over to our CFO, Rob Scott.

Thank you, Nestor, and good morning, everyone. Turning to the Q4 financial results. Revenue for the fourth quarter was $2.6 million, representing 9% year-over-year growth and a 6% sequential increase from the third quarter of 2023. This follows a similarly strong third quarter, which saw a 16% growth over Q2 2023. Our pediatric customer category had the strongest growth in Q4 with a 35% increase year-over-year. Heart Failure and Critical Care decreased 27% and 7%, respectively. Gross margin was 54.4% for the fourth quarter compared to gross margin of 56.9% in the prior year quarter. The margin decline is primarily driven by product and geographical sales mix and lower fixed overhead manufacturing absorption, leading to more efficient inventory levels. Selling, general and administrative expenses were $3.6 million in the fourth quarter, a decrease of 23% as compared to $4.7 million in the fourth quarter of 2022. The decrease in SG&A was primarily due to reduced head count and related compensation expense. Fourth quarter research and development expense was $1.4 million compared to $1.2 million in the prior year period. reflecting a modest increase in R&D spend related to the development of our new pediatric dedicated CRRT device as we approach IDE submission. In the current year period, the company recorded a nonrecurring expense reduction of approximately $800,000, reducing incentive compensation impacting both SG&A and R&D. Additionally, the company recorded a $550,000 SG&A expense in the current year period for contractual spend related to the SeaStar license and distribution agreement. Total operating expenses were $5 million in the quarter, a decrease of approximately $884,000 as compared to the fourth quarter of 2022. The period-over-period decrease was due to cost-saving measures implemented early in the second half of the year and carried through year-end 2023 as we continue to drive operating efficiencies.…

[Operator Instructions] Our first question today comes from Jeffrey Cohen from Ladenburg Thalmann.

Just a couple of questions from our end. So could you talk about the SeaStar Quelimmune device as far as any patient experience thus far? Or what you're saying is your second half launch?

The most of, if not all of the clinical experience with Quelimmune has been in the clinical study that they have done, that they have performed. We have not done any patients under the collaboration agreement yet. We -- now that we have the HD, the next step is for census in HDE approval. Each site needs to get their own IRB approval. So we are in that process right now and then the utilization can start.

Okay. Got it. And nextly, is the [indiscernible], the 12-centimeter one? Is that also being manufactured in your facility?

That is correct, yes. It has been manufactured in our facility and we plan to start selling it in the next 2 weeks.

Got it. And then could you compare and contrast with us. What's working in peds that's so beneficial on the top line growth and what's not working, in particular, in heart failure that's driving the decline?

Okay. Regarding the pediatric, the babies, this pediatric [indiscernible] started back in 2019 with a very landmark publication, which shows that when you have kids under 10 kilograms born with renal disease or absence of kidneys, having a continuous renal replacement therapy to act as the kidneys of the children is beneficial. However, there has not been a pediatric dedicated device. Most of this children's are treated with adult CRRT because of the Aquadex have such a slower rate raw rates as well as a very small extracorporeal volume of fluid. It became very safe, gentle and effective to treating these children under 10 kilograms. The fact of the matter is that it was not such a therapy, the results of this study show that patients under 10 kilograms treated with the Aquadex survived the therapy at a rate of 66%. So that's what drove our business. That started in 2019. And I'm just going to make apprentices here because that's exactly what is -- what we are seeing right now with the end-stage liver disease. So coming back to the pediatric, I mentioned the reason for this success on the pediatric because there is no other therapy. On heart failure, the decline is something that is explainable. We believe that now with the clinical data that we have, there would be more appetite for using the Aquadex in heart failure patients. We're still working on our evidence, that reimbursement. So once we get those in place, we'll see -- we expect to have an increase in sales.

And I can provide a little bit more color on just the heart failure decline specifically for the quarter. again, from dollars perspective, it was about $160,000 decline. Again, the percentages kind of get kind of wild, but the $160,000 was the total dollar amount. About $90,000 of that was driven by capital sales, so about a $90,000 reduction. So we had 3 less capital sales period-over-period. So again, a majority of that is driven by capital, which can be certainly bumpy from time to time. Utilization kind of made up the balance there. We had a couple of accounts that were just a little bit soft in Q3, just a handful of them. If there was both accounts sort of came in where we typically expect this quarter could have been even a better quarter for us as far as revenue goes.

That's helpful. And then lastly, first, could you talk about what's the current commercial footprint as far as FDA is out there and maybe give us a breakdown of the commercial organization focus in what particular areas.

We have about 23 people in the field right now. 9 of them are account managers, the other 14 are clinical specialists that provide clinical and technical support in the hospitals. And all the utilization growth that Rob just mentioned, has been purely organic.

[Operator Instructions] Our next question comes from Anthony Vendetti from Maxim Group.

So just on the SeaStar device, the SCD device. So because they have HDE, you can now go forward, but each hospital has to get their IRB. How long does that take? And are you targeting the hospitals where you already have relationships with your Aquadex system. And then what's the plan to rollout beyond that. Is that a multi-quarter plan? Or do you feel that as you start to commercialize it into your current base you could simultaneously start marketing this device with your device to other hospitals?

Good questions, Anthony. Let me see if I can answer the three question part there. The first one part was you talked about the period that it takes to get the IRBs, and it depends on the hospitals. Some hospitals will have IRBs that need on a monthly basis, on a weekly basis. So we expect those to be a lot quicker. Other ones use general IRBs so that may take a little longer. So that's on the IRB time of the IRBs. But the reason that they require IRB is because this is a humanitarian device exemption by the FDA is not the regular 510(k) approval. In terms of the overlap, which was the second part of your question, the reason why we believe that this collaboration is so strategically fit between the 2 companies is because of that. the majority of the centers that participated in the clinical studies of Quelimmune are the same customers that are using our product and are reporting on our products. So they are the top pediatric accounts in the United States. So there was a significant overlap on that. So the first 5 and this starts to answer your third part of your question of the first 5 accounts that we're targeting, 3 of them are top users of the Aquadex device. And then after that, we're going to roll out the following quarter. We're going to continue adding another 10 and so on until we have a full launch.

Okay. Great. And then obviously, since there is a lot of overlap, it seems like there's obvious cross-selling opportunities. does that go both ways? In other words, you SeaStar in some hospitals that you're not? And does that make it easier? Do you believe sell the Aquadex system as well.

Absolutely. By being there with Qualimmune it's an opportunity to talk about Aquadex, our current device and also started paving the way for our pediatric dedicated device.

That's right. And then on the cost-cutting, I heard a 40% cut in monthly costs. Can you outline where that is coming from? And then when did the cuts start happening, what month?

Yes, it started in March, March 1. And there are general expenses. We're becoming more efficient in our headquarters in terms of the people that we need for our strategic growth initiatives. It also includes travel and travel and expenses and also includes salary cuts for the executive team and also the board fees.

I see. And it doesn't -- it sounds like obviously critical to your success is the clinical specialists and the sales. So that's an area that has -- is pretty much I wouldn't say off limits, but hasn't borne the brunt of the cost cutting at this point. Is that correct?

Correct. Correct. We're not touching the sales organization as they are key for continuing our growth in 2024.

Okay. And then lastly, some companies at this stage also employ independent distributors. Is there an opportunity to do that to help further spur sales going forward?

Absolutely. Yes. We -- that's a very good point, Anthony. And we have 2 of them in key markets for us. One is in New York City and the other one is in Northern California. So we continue to look at opportunities to add more on this type of independent distributors.

Ladies and gentlemen, with that, we'll be concluding today's question-and-answer session. I'd like to turn the floor back over to Mr. Nestor Jaramillo, CEO, for closing remarks.

Yes. Thank you, everyone, for participating. As I mentioned before, we're very excited about the 2024. We continue to execute on our strategies redesigning our commercial strategy by adding DaVita and adding the collaboration with SeaStar. We'll also continue our product development with our pediatric dedicated device and we continue to -- committed to clinical research with our reverse heart failure trial. I want to thank all our stakeholders, including our employees, stockholders, medical staff, visions and health care workers without your help, we will not be able to achieve the transformation in the lives of patients suffering from fluid overload. Thank you.

Ladies and gentlemen, with that, we'll conclude today's conference call and presentation, we thank you for joining. You may now disconnect your lines.
