Thank you, Suzanne. Good morning, everyone, and thank you for joining us. Today we will discuss the third quarter results for our company and provide a business update. In March, we announced that our primary strategic focus going forward is on our psychiatry franchise and the late-stage development of NRX-101, our lead investigational compound. Today, we estimate the U.S. annual peak sales potential for bipolar depression with suicidality to be around $2 billion. There are only five drugs currently approved for bipolar depression, none of which is indicated for patients with suicidality. In fact, such patients were excluded from their clinical trials. Our Phase 2 study specifically enrolled patients with high levels of suicide risk and showed that NRX-101 has the potential to provide improved clinical outcomes in such patients, who is only currently approved therapeutical alternative is electroshock therapy. That is why the FDA gave us breakthrough therapy designation and a special protocol agreement allowing for registrational study with 72 patients. In recent months, we have made substantial progress in advancing our development of NRX-101 for the treatment of bipolar depression with suicidality and PTSD, while also exploring other psychiatric indications. In March, we announced the strategic decision to initiate our Phase 3 trial following the release of NRX-101 using processes suitable for ultimate commercial sale of our medicine should we demonstrate safety and efficacy. That milestone was completed and announced last week. Thus, we anticipate initiating our Phase 3 trial under the FDA special protocol agreement in 72 patients as pre-specified with the FDA by the end of this year. We expect to report top line data in the second half of 2023 with initiation of a potential NDA submission by year-end 2023, assuming efficacy and safety has been met. Last week, we also announced a debt financing…

Thank you, Stephen, and good morning, everyone. It's a pleasure to speak with you again today. And I would now like to review the highlights of our third financial results. For the three month period ended September 30, 2022 R&D expenses totaled $4.1 million, compared to $6.3 million for the same period in 2021. The decrease in R&D expenses related primarily to a decrease in clinical trials and development expenses related to ZYESAMI. As announced in March of this year, we are focusing most of our R&D expenditures on our psychiatry franchise going forward. For the nine month period ended September 30, 2022, R&D expenses totaled $12.6 million, as compared to $13.8 million for the same period in 2021. The net increase of $1.3 million is related to a decrease of $1.5 million in clinical trials and development expenses related to ZYESAMI, a decrease of $0.5 million in fees paid to regulatory and process development consultants, partially offset by an increase of $0.7 million in regulatory and process development costs. The nine month period includes R&D costs related to both to ZYESAMI and to COVID vaccine development, costs that we do not anticipate to incur going forward. For the three month period ended September 30, 2022, G&A expenses totaled $5.0 million, compared to $13.8 million for the same period in 2021. The decrease from G&A expenses was partially related to a reduction in consulting fees in 2022. For the nine month period ended September 30, 2022, G&A expenses totaled $21.9 million, as compared to $28.4 million for the same period in 2021. The decrease of $6.6 million was primarily related to a decrease of $12.3 million in consulting fees, a decrease of $3.4 million in stock-based compensation expense, partially offset by an increase of $4.1 million legal, professional and accounting…

Thanks, Seth. This is an exciting time for NRX. We believe that NRX-101 is a potentially life saving medicine that could change the treatment paradigm for individuals with bipolar depression, but are also experiencing suicidality. This is a driving force behind our mission of meeting the needs of underserved patients with serious CNS disorders. We have a variety of options with regard to commercial development. Our technology and robust IP portfolio have attracted strong interest and we have been approached by a number of potential partners regarding commercial partnerships for NRX-101. However, we are also prepared to support the commercial launch of this product still appove will be granted for NRX-101. We believe that due to the relatively small number of specialized psychiatric facilities in the U.S., a small company such as us is capable of marketing a first-in-class medicine to support this very high unmet medical need should our drug be approved. In addition, our team includes professionals, who have managed major debt launches to some of the world's largest pharmaceutical company. We plan to carefully evaluate all available options and make the decision that best meets the needs of patients, shareholders and NRX. We continue to execute across our portfolio with multiple near-term catalysts on track for the fourth quarter and next year, assuming the efficacy endpoints and Phase 3 [indiscernible] and Phase 3 clinical trial, we plan to initiate the rolling submission of a new drug application for the FDA by the end of next year. Operator, we are ready to take questions.

We will now begin the question-and-answer session. [Operator Instructions] Our first question comes from Vernon Bernadino of H.C. Wainwright. Please go ahead.

Hi. Thanks for taking my question. And Steve, congrats on the progresses made since coming on board. Just a few questions regarding the clinical trials, what type of data could we expect in first quarter from the ongoing Phase 2 with NRX-101 [MDB] (ph) with SSIB, sub-acute suicidal ideation behavior? And what end points are you considering for the Phase 2study with NRX in the PTSD?

Could I turn that to one of my experts? Yes, let me -- go ahead, Jonathan. Go ahead.

Thank you, Vernon. On the Phase 2 trial that's currently underway, the trial is actively enrolling and we expect that by the end of the first quarter we'll be able to talk about top line data, where the endpoint is depression is measured by the mattress scale and suicidality is measured by the CTISS scale. Those are the scales where superiority was demonstrated in the Phase 2b trial. With regard to PTSD, again, the depression scale will be a primary endpoint. However, in that case, we're also hoping to see a difference on the CAP-5, which is a scale that directly measures symptoms of PTSD in terms of your memory, what people commonly call flashbacks and other debilitating symptoms of PTSD.

Terrific and as one follow-up regarding the manufacturing that you mentioned, what if any activities are needed to fully establish such as testing runs, the manufacturing capability or process in the U.S.? And when do you expect to have supplies from that process for your clinical trials? Thank you.

Well, the press release that was issued announced that the supplies for the Phase 3 clinical trial has been released and the module three manufacturing file has been filed with FDA. So there will be additional replication runs in order to demonstrate the replicability of the manufacturing practice. And of course, we're sure FDA will have some comments around the manufacturing file. But as Steve emphasized, the material that's now been released for Phase 3 use was manufactured using commercial processes, so that we hope when should we demonstrate safety and efficacy that we'd be able to move directly to distribution and plant inspection with F&A for additional bridging studies.

Perfect. That's all of the questions I had today. Thank you.

Thank you for your question, Vernon.

The next question comes from Ed Woo of Ascendiant Capital. Please go ahead.

Yes. Also congratulations on the progress. For PSTD, do you guys have a specific timeline when you guys would initiate for that indication?

No, I think it's too early. Our work with PTSD is in its developing stages. So once we've got some work under our belt, we'll be able to give you more of a timeline for it.

Great. And my last question is, have you guys thought about the international opportunity for NRX-101?

Yes. We have, as I mentioned, we have interest from people who are -- would like to partner with us and they have appreciated the international interest -- an international potential of NRX-101 to a great deal.

And, you know, those who follow the literature closely will note that France has actually published perhaps the most extensive trial of ketamine for treatment of suicidal depression, both in the context of major depressive disorder and bipolar depression. And in fact, that trial showed that bipolar depression was much more susceptible to effective treatment with an NMDA antagonist, the major depressive disorder. So there is considerable interest being demonstrated in our pipeline if you follow the published literature.

Great. Well, thanks for answering my question and I wish you guys good luck. Thank you.

Thank you, Ed, We appreciate your being with us.

This concludes our question-and-answer session. I would like to turn the conference back over to Suzanne Messere for any closing remarks.

Thank you, Andrea. We would also like to address a couple of questions that we have received. And this question will go to our management team, and it is how is NRX Pharmaceuticals preparing for the Phase 3 study and potential NDA submission in 2023?

Well, as we've said in the call, we are planning to initiate the Phase 3 targeting bipolar with a acute suicidality by year end. We have identified as CRO, we are working with our principal investigator, we have several confirmed clinical sites for our trial. Further information will be on the website clinicaltrials.gov. We've invested in developing commercial manufacturing processes, full tech transfer was recently completed and corresponding manufacturing file update was submitted to the FDA. So those are some of the things, but not all by any means than we're doing as we prepare for our Phase 3.

Thank you, Stephen. And then we have one additional question. The healthcare environment is increasingly cost constrained. What feedback have you gotten from payers regarding the use of your investigational medicine?

In today's reality, the only approved therapy patients with suicidal bipolar depression have is electroshock therapy. Our analysis of payer data suggests that such patients incur more than $40,000 in annual healthcare costs, experienced multiple hospitalizations and tragically harmed themselves all too often. A research with payers and prescribers regarding the likely marketplace acceptance of an oral medication that could benefit patients with suicidal ideation and behavior show the high interest. The feedback we received demonstrated strong support for such a mitigation, payers are aware of the high-class of hospitalization that can go up to two weeks and indicated that costs of less than $10,000 per patient for therapy should we experience no formulary restrictions for treating patients might be a positive development.

Thank you, Stephen. And actually one last question. If your drug ingredients have previously been used for other reasons, why do you have composition of matter patent protection?

So, it's terrific. And I think I'm glad we got to have this question, because we are so -- it is so important that we have composition of medical effects with regard to our drug, it clears the field of competitors quite nicely. D-cycloserine has been used worldwide to treat tuberculosis, but it has largely been replaced by newer anti-infectives in part because of its propensity to cause hallucinations. Lurasidone has been used to treat schizophrenia and bipolar depression, but bears a black box warning, because of its propensity when shared with all drugs of its class to cayse Akathisia and suicidal ideation. Our Co-Founder, Professor Daniel Javitt, who is one of the world's 1000 most quoted scientists, discovered the unique synergy to between NMDA antagonist, such as D-cycloserine and 5HT2a antagonist, such as lurasidone, when these classes of drugs are administered together, the 5HT2s component is shown to block the hallucinations that would otherwise be caused by the NMDA drug. And the NMDA component is shown to block the active seizure that would otherwise be caused by 5HT2a drugs prior to this discovery by Dan Jevitt, the synergy had never been identified and it's now deemed by patent examiners all over the world to constitute a novel composition of matter.

Thank you once again. And thank you to everyone for participating today, that is all the time we have for questions. And this concludes the NRX Pharmaceuticals third quarter 2022 results conference call. And again, thank you all for participating. Andrea, we're ready to close the call.

The conference has now concluded. Thank you for attending today's presentation and you may now disconnect.
