Thank you, Matt. Good morning, everyone and thank you for joining us. 2023 has been a pivotal year, both for NRx and for the field of interventional psychiatry and its approach to suicidal depression in PTSD. Last week, we were invited to give a ketamine presentation of the 2024 International Ketamine Conference held at Oxford University. It's now 37 years since Daniel Javitt and his colleagues at the Albert Einstein School of Medicine made the unprecedented discovery at the NMDA receptor of the brain is key to understanding schizophrenia and depression. It's 25 years since Rob Berman and his colleagues at the Yale University made the equally surprising discovery that NMDA antagonist in this case, ketamine can achieve rapid reversal of depression and later discovered the same for suicidality. Now on the tale of the COVID pandemic that practically put the science on hold for 2 years, it's clear that thought leaders in psychiatry have concluded that ketamine is a standard of care treatment for acute depression and suicidality and is at least as effective, if not more effective, than electro-convulsive therapies. Ketamine infusion has moved from the hospital and the emergency ward to community clinics and some believe it should move to the home. We at NRx are on the cusp of that conversation. The problem with ketamine, of course, is that while it's dramatically effective in the short term, well-designed studies reported in the past 2 years, have demonstrated that it's neurotoxic. In other words, it kills brain cells when given for months at a time, even at the low dose it is used to treat depression. Data from Stanford and elsewhere documents conclusively that ketamine not only blocks the NMDA receptor but also binds to the opioid receptors that have been so central to the opioid crisis in the United States. That's why even as we launch Hope Therapeutics to cease to make short-term ketamine available to all insured patients as a life-saving therapy, not just to those who can pay out of pocket. We focus on NRX-101 and perhaps future non-addictive, non-neurotoxic medicines that also target the NMDA receptor without those side effects. We already have scientific evidence that NRX-101 works to preserve the ketamine effect. As a follow-on drug for ketamine, it has the potential to help hundreds of thousands of patients. In the next few weeks, now that we're completing database lock on our clinical trial. We will have a first glimpse of whether NRX-101 is also sufficiently potent to treat severe depression and suicidality without prior use of ketamine and to do so in the outpatient setting. In our 10-K, we made a brief comment about a new opportunity that's still evolving to partner with the French: Fondation FondaMental on a new drug with an entirely different mechanism of action that may represent the first drug in human history to reverse the brain injury that causes schizophrenia, not nearly to treat schizophrenia's devastating symptoms. Thus, we deeply appreciate the trust that you, our shareholders, have imparted as we emerged from a COVID pandemic and returned to our core mission in CNS disease. At the end of 2022, the company's Board and management had a single clinical trial initiated in bipolar depression, had no commercial stage partners and $11 million in debt. In 2023 and the year-to-date, we've secured a global commercial partnership for the first indication of our lead drug NRX-101, we've received a $5 million advance on potentially $330 million in milestones for that indication. We've expanded our patent portfolio to include the use of NRX-101 in chronic pain. We've opened an FDA IND and await efficacy data for chronic pain. We've obtained efficacy data for the use of ketamine and suicidal depression from both national clinical trials and positioned ourselves to seek FDA approval for ketamine in 2024. And finally, we've maintained unexpected data that demonstrates the efficacy of NRX-101 in treating complicated UTI and Pyelonephritis with accompanying recognition from the FDA in the form of qualified infectious disease product and Fast Track designation. We've done that with a dedicated team of fewer than a dozen scientists and business leaders together with your financial support. While achieving these scientific advances, we've created a new subsidiary, Hope Therapeutics which has completed manufacturing of the first batch of releasable ketamine that will be distributed under national pharmacy licenses even as we seek FDA new drug approval. Our 2023 development partnership with Alvogen and Lotus Pharmaceuticals, to develop our lead candidate NRX-101 in suicidal bipolar depression is key to a global launch of NRX-101 to treat bipolar depression worldwide. In March, we recorded last patient last visit in that clinical trial of NRX-101 versus Lurasidone. In 2023, we published a peer-reviewed randomized trial led by Professor Andrew Nierenberg from Harvard Mass General, demonstrating that NRX-101 significantly reduces both depression and suicidality after ketamine compared to that standard of care drug. The purpose of this trial is to see if we can demonstrate effectiveness of NRX-101 without prior use of ketamine. We expect to lock the database from the trial this week and we expect to be reporting top line results from the trial this month. Positive results from this trial and comments from the FDA will trigger an additional $4 million milestone from Alvogen and begin transfer of all expenses related to NRX-101 for bipolar depression to our partners. In addition, we're eligible for an additional $320 million in milestones plus a royalty that reaches 15% on net sales. So the NRX-101 demonstrate success, either as a stand-alone drug -- as the drug to preserve the known efficacy of ketamine or both, NRX-101 has the potential to be used in the therapy of millions of Americans and many more around the world who suffer from bipolar depression and whose only approved therapy today is electro shock therapy. The partnership agreement leaves NRx the potential to continue to own and to develop NRX-101 for the much larger indications of PTSD and chronic pain. With the database lock, we expect to report top line data later this month. Our patents on NRX-101 cover both composition of matter and its method of use to treat many forms of depression, PTSD and chronic pain. In 2023, we partnered with Professor Vania Apkarian and his research team at Northwestern University around the use of NRX-101 in treating chronic pain. Their 2016 clinical trial demonstrated efficacy on a post-hoc analysis and this week, they're achieving data lock on a 200-person Department of Defense funded trial that seeks to replicate the -- efficacy findings. In today's world, there's essentially nothing to treat chronic pain that bridges the relatively mild effects of Tylenol and Motrin like drugs on the one hand and the potent but addictive and dangerous class of opioids on the other. The magnitude of the effect in chronic low back pain seen in the 2016 trial was such that a replication of that finding could provide a pain drug that has an effectiveness that's close to opioids but a safety profile that's far closer to the non-opioid pain drugs. We aspire to unlock a path to breakthrough nontoxic addictive pain drugs that could improve the lives of some 50 million American adults who suffer from chronic pain and nearly 0.5 billion around the world. This partnership in 2023 on chronic pain for NRX-101 has not diminished our interest in pursuing an indication for NRX-101 in post-traumatic stress disorder and the Oxford conference last week made clear that NMDA antagonists have enormous potential to treat PTSD. Thus, we hope to initiate our work in PTSD later in 2024. As we announced, we incorporated Hope Therapeutics as a specialty pharmaceutical company to advance and commercialize intravenous ketamine for suicidal depression. Initially, we expected that ketamine would be developed by others for the treatment of bipolar depression. However, the scientific record thus far suggests that intravenous racemic ketamine, i.e., the form that we're manufacturing and expect to deliver is effective in rapidly reducing suicidality and depression, while nasal and other forms of administration may be less effective. In 2023, we partnered with leading researchers to be able to submit definitive efficacy findings of government-supported placebo-controlled trials for the FDA in support of new drug approval for ketamine when we embarked on this mission, we always expected ketamine to outperform placebo based on 20 years of academic research findings. The surprise of 2023 was the release of the 400-person Harvard led patient-centered outcomes research initiative or PCORI initiatives that demonstrated a larger antidepressant effect for ketamine then for electro shock therapy with none of the undesirable side effects of ECT such as short-term memory loss. The PCORI group is now embarking on a larger trial in patients with suicidal depression and we look forward to partnering with them in that process. Hope is a specialty pharma company, not a drug development company. We've already been offered term sheets profiting more than $60 billion of funding for Hope because of the recognition that the paradigm for treating suicidal depression is changing as we speak and understanding the old model of hospitalization and electro shock is rapidly becoming a second-line therapy. Yet the evidence is clear that the ketamine effect is measured in days to weeks and that long-term repeated use of ketamine mainly to addiction and neurotoxicity. Therefore, we believe that NRX-101 may well have a long-term role in transforming the lives of those who suffer from suicidal depression. Hope will incorporate other therapies, including potentially digital therapeutics as it seeks to build a network of lifesaving care around patients who today have a higher mortality risk than those who suffer from breast cancer, prostate cancer and other common malignancies. The rate-limiting step in filing a new drug application for ketamine is having a new drug in your hands with which to apply. It's easy to say, well, let's just apply to the FDA for a label but you actually have to have a drug with which to do it. The formulation and presentation of ketamine as an anesthetic dates to the Korean War. It's an old drug that is increasingly plagued by critical drug shortages as reflected on the FDA database. We partnered with Nephron Pharmaceuticals of South Carolina to develop a new formulation and diversion resistant presentation. FDA regulations require at least 9 months of stability in the presentation you intend to market before you can file for a new drug approval and we will reset time point this quarter. At the same time, given the critical drug shortage of ketamine that's been announced by FDA, we're partnered with Nephron to deliver Ketamine immediately the high-quality clinics who will 1 day form the backbone of Hope's delivery system. Last week, the first batch of ketamine was approved for shipment in a pharmacy presentation and on the loading dock. To augment and expand the efficacy of IV ketamine, we're beginning to work on a companion digital therapeutics. I previously participated in developing such a digital therapeutic for the U.S. Navy to result -- to reduce stress in war fighters. It's an effective product that's still in use. We'll build on that learning and technological advances to help suicidal patients get back on track. Additionally, as a proprietary product, this will enhance our market exclusivity. We're sure that some of you are curious about why we invested a small amount of capital, really less than $100,000 and establishing an indication for complicated UTI and Pyelonephritis for NRX-101. First of all, this condition affects 20% of Americans who develop urinary tract infections and that percentage is climbing as antibiotics that have served us well for 50 years, increasingly fail. Of the 15 million Americans who develop UTI every year, 3 million who progress to complicated UTI and at least 15,000 die of urinary sepsis. D-cycloserine is an interesting drug. It works by a completely different mechanism than other antibiotics and it's the only antibiotic that's highly concentrated in the urine. There's no evidence that it can cause the debilitating diarrhea and other side effects of the new fourth line antibiotics. And most importantly, it can be given by mouth whereas many of those require intravenous administration. DCS fell out of favors in [ph] antibiotic in the 1960s, in part because of its propensity to cause mild CNS side effects. However, we seem to have neutralized those side effects with the addition of Lurasidone to NRX-101. The mechanism of action is simple. In a brain cell, DCS mimics the amino acid glycine and inhibits the NMDA receptor. In a bacterium, however, DCS mimics the amino acid alanine gets incorporated into the cell wall and causes the bacteria to explode. Animal cells don't have cell walls. So this effect is seen only in bacteria. The peer review data for NRX-101 in the treatment of bugs that cause complicated UTI were just published in the peer-reviewed literature last week and we invite you to read the results. At any rate, now that we know that NRX-101 is a potent agent against resistant bacteria that harm millions of Americans, we expect to identify a product already engaged in antibiotic marketing for this opportunity. It's important to understand what that FDA QIDP designation means. It means that even without a patent for use of DCS in antibiotics, we're entitled to 5 years of market exclusivity, fast track designation and priority review. That's why we think this drug has a real application as we identify a partner in the anti-infective space. Steve's now going to address some of our corporate achievements during 2023 and the quarter that follows.

Thank you very much, Jonathan. As you know, I joined NRx as CEO in July 2022. My job was to reduce a daunting cash burn and help align the management team into a dedicated group that has the potential to take our drugs to market. Although we have not yet generated our first dollar of revenue, we have demonstrated progress that motivated a discerning corporate partner to advance its milestone payments for our first clinical indication. Not only have we survived 2023, we expect to see the revenue flow from commercial operations begin by the end of 2024. That's clearly a forward-looking statement but 1 that we believe is within our capacity to achieve. Everyone on this call knows that 2023 was possibly the worst year in the history of the biotechnology industry and many premarket biotechnology companies did not survive. We emerged from 2023 on a more solid front than we entered and are poised for ongoing success, particularly if the clinical data we read out later this month is positive. Even if 2 highly promising trials don't give us the short-term answers we seek, we project that the Ketamine foundation we have built will yield positive cash flow by the end of 2024, a belief that is reinforced by the response we have received from large institutional investors. On the corporate front, we have raised approximately $17 million in new capital in addition to working capital since the beginning of 2023. Additionally, we have reduced corporate debt by more than 50% from $11 million down to approximately $5.4 million through the first quarter of 2024. Finally, we have taken steps to maintain our NASDAQ listing by first, achieving compliance with the market value of listed securities requirement, and then affecting a reverse split to comply with the $1 minimum bid price by their design and combating illegal shorting of NRx securities, all to support shareholder value. It's important that we keep our share price in a zone that is investable by high-quality institutions. I'm incredibly proud of our team, grateful to our partners and investors as well as all of the patients who have participated in our clinical trials. We look forward to advancing the company and further continue this growth. In December, we were delighted to add nationally recognized attorney, Janet Rehnquist to our company's Board of Directors. Janet brings vast experience and insight to our company in critical areas and we welcome her. I expect you will see us add other members to our Board who have direct experience in the commercialization of pharmaceuticals as we move from pure research and development to commercial operations. Jonathan has explained some of the value drivers that underline our focus on Hope Therapeutics. To build value for NRx shareholders, we intend to distribute shares of Hope Therapeutics to existing shareholders in the near term. and then to gain a public listing for the company on a national exchange. We have received considerable interest from investors, both for a bridge round to get our listing and a more substantial rate to support the launch of the product. We are actively building out our team, partners and network with the goal of launching the product at the beginning of 2025. Delaware corporate law requires us to deliver on a dividend within 60 days of declaring it. Thus, we are waiting until we have the audit and SEC filings in place to launch Hope prior to officially declaring the dividend. Some may ask, given that Ketamine is a generic drug, why the FDA approved -- why seek FDA approval for use in depression? Simply put, without FDA approval, the only people who have access to this life-saving treatment are those who can pay cash. FDA approval is key to insurance reimbursement. Our discussions with clinics to date have indicated the lack of reimbursement as the key impediment to patients getting the treatment they need. We aim to solve this problem. In advance of this, there is still a considerable need for high-quality, reliable sources of ketamine. To that end, we have formed collaborations with the 503A and a 503B pharmacy to provide ketamine to clinics in need. First lots have recently become available and sales can commence shortly. Additionally, these near-term activities will serve as an excellent entree into those clinics once our NDA is approved and we have full licensed and reversible product to offer. As you can see, we have been careful stewards of your funds. We have trimmed our operating expenses, reduced our corporate indebtedness, brought in non-dilutive partnership support realigned our executive team and expanded our pipeline to a robust clinical development program with a multibillion-dollar potential. We will work hard every day to bring these to reality and to bring Hope to life. I will now ask Rich Narido, our CFO, to review the fourth quarter financials. Rich?

Thank you, Steve and good morning, everyone. I will now review the highlights of our fourth quarter and full year 2023 financial results. Before reviewing the numbers, it's important to recognize that we have consistently reduced our cash expenditures and expect to further reduce those expenditures as we have completed the NRX-101 clinical trial, expecting data lock imminently and expecting data readout early in the second quarter of 2024. For the 3 months ended December 31, 2023, we at NRx Pharmaceuticals reduced our net loss from $10.2 million in the final quarter of 2022 to $4.3 million in 2023, representing nearly a 60% improvement year-over-year. For that same period, we reduced research and development expenses from $4.5 million in 2022 to $2.5 million in 2023, while substantially improving and finalizing our clinical trial enrollment. The $2 million decrease is related primarily to a decrease of $1.1 million clinical trial expenses, $0.6 million in stock-based compensation and $0.2 million in consulting and personnel wage costs. Also in that 3-month period, we recorded a 67% reduction in general and administrative expenses from $5.4 million in 2022 to $1.8 million in 2023. The decrease of $3.6 million is related primarily to a decrease of $1.3 million in insurance expense, $1.3 million in stock-based compensation, $0.5 million in employee expenses, $0.2 million in legal and professional consulting fees and $0.2 million in franchise tax expenses. For the year ended December 31, 2023, NRx Pharmaceuticals reduced net loss to $30.2 million compared to $39.8 million in the prior year. These efficiencies represent an improvement in net loss of nearly $10 million year-over-year and a $0.20 or 34% improvement in our net loss per share year-over-year. Over the annual period, we recorded $13.4 million of research and development expenses compared to $17 million for the same period in 2022, representing a 21% decrease year-over-year. The decrease of $3.6 million is related primarily to a decrease of $2.1 million in clinical trial and development expenses, $0.9 million related to fees paid to regulatory and process development consultants, $0.8 million in stock-based compensation, while offset by a $0.2 million increase in patent costs as our patent portfolio has expanded. Please note that the improvement in G&A expenses is even larger than the improvement in other areas. We decreased G&A by $13.1 million from $27.3 million in 2022 to $14.2 million in 2023, nearly a 50% decrease year-over-year. As of December 31, 2023, we had $4.6 million in cash and cash equivalents. Over the first 3 months of 2024, we improved our access to working capital by $8 million in total, representing $2.9 million from equity sales and $5.1 million from the Alvogen milestone advance, while reducing our corporate indebtedness by 50%. We continue to implement operational efficiencies to extend runway and focus on our path to generating revenue. We believe that the near-term delivery of clinical trial data and the planned launch of Hope Therapeutics, will be defining events in the second quarter of 2024. With that, I will turn it back to Jonathan for closing remarks. Jonathan?

I think it's time to take questions.

[Operator Instructions] Our first question comes from the line of Tim Moore with EF Hutton.

You made a lot of great progress over the past few quarters. And like you said, it wasn't easy in biotech land last year and you came out even stronger. I was just wondering maybe, Jonathan and Matt, if you can elaborate more on the Hope in digital therapeutics, maybe give investors a little more color on the anatomical coherence, the software possibility there, just pathways and just what you're thinking as a development route over the next year or two?

Thank you, Tim. And it's really exciting to see you and people of your caliber joining our calls. So this area of digital therapeutics really began in the military. It began with a recognition that if you can teach someone to synchronize breathing and heart rate which for years has been achieved through medication but that's extraordinarily difficult for most people to master. You actually reduce physiologic evidence of stress you can show reduction in serum cortisol levels and other hard laboratory findings. So what was done back in the early 2000s with funding from DARPA, the Defense Advanced Research Projects Agency, was to build something that looks like a video game but you actually win the video game by synchronizing breathing and heart rate. And the target audience at the time was special forces operators. I was involved in a demonstration project where a group of Navy special forces operators went through the combat simulator in Quantico, both with and without using this technology and demonstrated not only improved combat performance but substantially reduced measures of stress and depression on the back end. So much so that the product remains for sale within the military. Well, the challenge we have is as the paradigm shifts and people recognize that ketamine achieves a rapid reduction in both suicidality and depression, the question is how do you maintain that effect? Because if you keep giving ketamine for months at a time, at least the clear evidence from primates is that you're going to kill brain cells. So one of the things we're pursuing is civilianizing that population that was developed with millions of dollars of Department of Defense R&D into something that can be useful for patients who are coming to ketamine clinics. Of course, we hope that they'll take NRX-101 on a long-term basis once we have demonstrated that efficacy and gotten FDA approval for it. But we also think that these kinds of digital technologies have real potential. And not only that, if they become part of the label of the drug, they extend the intellectual property horizon of that drug. So, I hope that begins to give you a sense and we're going to hope to do a teaching on that sometime over the next quarter.

That's very helpful. Yes, I look forward to that key chain [ph] but I can get a better sense of the optionality there and it just seems like it's such a good untapped market nobody else is playing in and you have a pretty good first mover advantage. My other question is around your database lock occurring, it sounds like this week, top line data probably by the end of this month. Can you just walk us through the next 2 steps you plan to take? And maybe just provide more details on that. If you were to just give us a sense of kind of the road map over the next 12 months now that the top line data will be coming out.

Well, database lock means that we have once and for all confirmed every endpoint from the patient forms in the study site through the database and at that point we hand the data file to the statisticians and they perform the statistical analysis according to the SAP, the statistical analysis plan. And we've put that up on clinicaltrials.gov so anybody who wants to read it should be able to. If the data are positive, the plan is to conduct a meeting together with Alvogen with the FDA and to gain FDA's alignment on a registration study that would bring NRX-101 to market for patients with severe depression and suicidal ideation. Remember, we previously showed that the drug works after ketamine. That's why FDA gave us breakthrough therapy. So the purpose of this trial is to see whether the drug can work without priorities of ketamine. Either way, depending on the results of this trial, we're going to be going to FDA and saying we want to bring the drug to market, either with or without requiring prior use of ketamine and aligning on the final design of that study. Now one of the things we're likely to be able to do, is to do the trial against placebo if we're not working with acutely suicidal patients which is a much easier trial and a trial that has a much higher probability of success. Remember, in this trial, we're comparing NRX-101 to a known effective drug, namely lurasidone. If we're comparing NRX-101 to placebo -- that cut comparisons already succeeded in numerous academic studies.

Great. Thanks for those added details and color. And I really appreciate your methodical strategic plan that you shared. And that’s it for my questions this morning.

Our next question comes from the line of Ed Woo with Ascendiant Capital Markets.

Congratulations on the progress you've done. Have you talked about your pricing or reimbursement strategy for ketamine?

Well, as you know, there is an approved form of ketamine that's for sale in the marketplace today, it's offered by J&J. And J&J's reported sales in, I think, above $600 million associated with that drug. So there's an established market. The problem is that drug is not only not indicated for bipolar depression. And you know that about 40% of the people who commit suicide have bipolar depression, there's a REMS around that drug that precludes its use in people with bipolar depression. So we think there's a real pricing opportunity. You're in a better position than we are to advise the public as to the current pricing of that currently marketed drug. But as we have third-party indications of pricing, we'll certainly report them. Suffice it to say that if you can get insurance coverage for people, payers have indicated a real willingness to pay for the therapy because the alternative of psychiatric hospitalization and electroshock therapy is something that -- first of all, is horrible for patients. And second of all, costs payers the better part of $40,000 in the first year. So we believe there is a market opportunity but we're certainly going to be guided by the security analysts as well.

Great for the details. And thank you for answering my questions. I wish you guys good luck. Thank you.

There are no further questions at this time. I would like to turn the floor back to Matt Duffy for any closing remarks.

Thank you, everyone. That's all the time we have for today. We appreciate you joining us this morning and this concludes the NRx Pharmaceuticals fourth quarter '23 and full year conference call. Thank you all for participating.

This concludes today's teleconference. You may disconnect your lines at this time. Thank you for your participation.
