Thank you, David, and thank you, everyone, for joining the call. I will arrange my remarks to highlight key takeaways for the third quarter, year-to-date and provide updates of our two platform programs, before I pass it back to David to discuss our financial results and upcoming milestones. Then we will move to Q&A. I'll start with our DN-TNF program, beginning with XPro1595, which we are developing for Alzheimer's disease and other CNS indications where neuroinflammation plays an important role. A significant highlight since our last quarterly update was the announcement in September that we were awarded a $2.9 million SBIR grant from the NIH to support a Phase II study in XPro1595 in patients with treatment-resistant depression. In rough numbers, we expect to receive $0.75 million this year, $1.2 million in 2021 and the balance in 2022. Importantly, we will conduct this trial in collaboration with two of the world's pioneers in this field, Professor Andrew Miller, MD; and Associate Professor, Jennifer Felger, both at Emory University. Treatment resistant depression is an indication with a significant unmet need. An estimated 7 million patients in the U.S. with major depressive disorder are resistant to current therapies. The definition of treatment resistant depression is simple: the patient must fail two lines of treatment for their depression to be labeled treatment resistant. There are two surprises hidden in that simple statement. The diagnosis is one that one comes to by trial and error of treatment. There are no biomarkers that predict which patients are going to be successful or fail or which drug you should use. Imagine a disease with 7 million patients is treated with the diagnostic precision of some ancient time, namely hit and miss. I find that remarkable. This trial hopes to change that, at least to begin the process of changing that. The trial will use biomarkers of inflammation to enroll patients and will use biomarkers to determine responsive therapy with XPro, a strategy that is rarely, if ever used in the development of psychiatric drugs. Based on our work using XPro to treat patients with neuroinflammation in Alzheimer's disease, we believe treatment with XPro will decrease neuroinflammation in the patients with treatment resistant depression. We will restore functional connectivity in a reward-related brain circuitry, an MRI neuroimaging biomarker that can be seen and will improve anhedonia, an important symptom of major depression, which is sort of apathy, and they just can't get excited about anything. A more detailed discussion of this biology in the trial is beyond the scope of this call. I refer you to our September 29 KOL webinar that is posted on our website. Needless to say, we are excited about the expansion of our neuroinflammation franchise beyond Alzheimer's disease and look forward to commencing enrollment of this trial in 2021. Turning to our flagship program in Alzheimer's disease. In July, we presented interim data from a Phase I trial using XPro1595 to treat neuroinflammation in patients with Alzheimer's disease. XPro reduced neuroinflammation by an average of 40.6% in a white matter pathway, important for language and memory in patients with Alzheimer's disease. In this study, neuroinflammation is assessed in many ways. But as part of this preliminary data snapshot, we focused on MRI measures of white matter free water, a validated biomarker of neuroinflammation. In the admittedly small preliminary data set, we had six patients, half in a low dose and half in a high dose cohort - excuse me, that were treated for 12 weeks. As a reminder, this trial is a neuroinflammation trial in Alzheimer's disease - in patients with Alzheimer's disease. The primary endpoint is decreasing neuroinflammation. We are measuring cognitive changes, as in a 12-week trial, the expectation for significant changes is tempered. There were several important findings in this preliminary data set. First, neuroinflammation was decreased over the 12-week period as measured by white matter free water. White matter free water was measured in two ways, a whole brain measure using a safe white matter mask, and we looked at neuroinflammation in specific white matter tracts, the superhighway of the connecting parts of the brain. Using the safe white matter mask, we saw a clear dose response with an increase of 1.7% of neuroinflammation over a 3-month period in the low dose group, but a decrease of neuroinflammation of 2.3% in the high dose group. In a more detailed analysis of white matter tract pathology, we showed a 40% reduction of neuroinflammation in the arcuate fasciculus in patients treated with XPro. Every patient had a decrease, and the range was between 20% and 50%. Why do we believe a decrease in neuroinflammation in the arcuate fasciculus is important? The arcuate fasciculus is a major white matter tract that connects regions of the brain important for language and short-term memory. Language, more specifically, the deterioration of language skills, is a sensitive clinical sign used by clinicians in Alzheimer's disease. Language skills or the deterioration of language skills are helpful in the diagnosis of MCI and to monitor the progression of MCI to Alzheimer's disease and to measure the worsening of cognitive decline. We acknowledge these are preliminary data in a small number of patients. Regardless, we are encouraged by these results for three reasons. First, the results are predicted by preclinical studies. Second, we treated Alzheimer's patients with a novel therapeutic protein by subcutaneous injection in thigh or the abdomen like an insulin shot to decrease neuroinflammation in a specific nerve anatomic structure that is important in one of the most sensitive clinical signs of Alzheimer's disease, language. We believe this gives us considerable optimism. Finally, by measuring white matter free water using a sensitive, and I stress, noninvasive biomarker, we will increase the precision and decrease the risk of drug development in Alzheimer's disease and the other neurodegenerative diseases we will be looking to in the future. We look forward to expanding the data set in the patients of the Phase I trial and studying patients who have entered the extension trial. The extension trial is for patients who reached their 3-month deadline or treatment end of study and want to stay on the drug; they get treated once a week for the long term. I encourage you to review the July 13 webinar, Cash on the INmune Bio YouTube channel to gain further insight into the data. This data gives us confidence in our plans to initiate two phase trials in 2021, one in treatment-resistant depression that I've already mentioned, supported by the NIH and one will be a Phase II trial in Alzheimer's disease. We are no longer alone in believing that neuroinflammation is an important pathology associated with CNS diseases. Our approach of targeting neuroinflammation caused by the dysregulated anhedonia system has received votes of confidence in the form of funding from the National Institute of Mental Health, the Alzheimer's Association and the ALS Foundation. We remain confident that our focus on targeting real activation combined with the use of biomarkers in patient selection and function provides a path forward. On to Quellor, the name of our program for treating hospitalized patients with COVID-19. We have a simple hypothesis related to the pathology of the disease in this pandemic. First, patients are hospitalized because of COVID-19-related cytokine storm. Second, we believe blending, suppressing, eliminating, or curtailing that cytokine storm will benefit the patient, decrease symptoms and decrease pathology. Finally, we believe how you attack the cytokine storm matters. We believe TNF is the master cytokine of a cytokine storm, and that's what Quellor targets. We're testing these principles in a Phase II clinical trial in patients with respiratory compromise due to COVID-19 infection. Why do we think blocking TNF will be important? TNF decreases the expression of IL-1 and IL-6, the other major cytokines of the cytokine storm. So that is, if you cut the knees out of the TNF, IL-1 and IL-6 don't get upregulated. There are three additional, what we call, TNF pathologies that are important to the progression of symptoms in these hospitalized patients. First, as I mentioned, TNF causes activation of the innate immune system, the driving force of the hyperimmune response. TNF also causes activation of endothelial cells. Endothelial cells are the cells that line the blood vessels. Activated endothelial cells express ICAM, VCAM and tissue factor. The first two, ICAM and VCAM, direct transmigration of activated immune cells from the blood to the tissue. They have - these activated cells must be in the tissue to cause damage, and they need to be directed to go there; that's what ICAM and VCAM do. Tissue factor causes blood clots. You've all heard that aberrant blood clots seem to get stuck in the blood vessels of the lungs, the kidneys, the heart, the brain and beyond and contribute to the catastrophic complications of COVID-19. We believe that the blood clots are one of the major problems associated with the vexing viral disease. On September 1, we announced the FDA accepted our IND application, paving the way for the initiation of the Phase II clinical trial, evaluating Quellor to treat patients who have respiratory compromise and are hospitalized due to COVID-19. We aim to enroll 366 patients in a randomized trial with a 1:1 randomization. One, the control group will get standard of care, and the treatment group will receive standard of care plus Quellor as a single injection on admission to the hospital. Last quarter, we announced that our INB03 oncology program was delayed due to the pandemic. We hope to initiate the Phase II trial in MUC4 positive cancers next year, assuming the pandemic has been controlled. Although the clinical part of this program is dormant, the laboratory research continues. We're looking at the combination of INB03 with TKIs in MUC4 expressing tumors. Similarly, our LIVNate program in NASH will not begin a Phase II trial until the pandemic has been controlled. We hope to have more clarity on these two programs by the end of the year. In the meantime, however, we are all in, in progressing our neuroinflammation programs and the cytokine storm program focused on COVID-19. So that's what I have to say about the dominant negative TNF platform. I'll now move to INKmune, which is our NK cell priming platform. NK cells play a critical role in cancer outcomes, given their importance in targeting residual disease, one of the primary causes of cancer relapse. INKmune restores the function of patients' own NK cells to attack residual disease. And we believe that by eliminating residual disease, INKmune should prolong survival. We have two therapeutic programs in the queue, high-risk myelodysplastic syndrome or MDS, a precursor to acute myeloid leukemia that predominantly affects elderly patients. The second program is ovarian cancer, a previously uncurable malignancy. We plan to initiate a single-center Phase I trial in high-risk MDS, a first-in-man study using the product in the near future. The company is ready to go, but the U.K. is suffering from a resurgence of COVID-19, like we are in the U.S. So the development timelines in the U.K. are being compromised. We plan to - for when the clinical site is ready, we will be able to support admission of patients to the clinical trial. The high-risk MDS trial will include at least nine patients. The ability to expand both the number of centers and the number of patients will depend on ongoing results, both in the treatment as well as controlling the pandemic. Likewise, the ovarian cancer program is delayed because of the pandemic. We are hopeful to start enrolling patients in 2021. We remain aggressive in pursuit of new IP and expansion of existing IP. In August, we were granted a European patent covering the peripheral administration of XPro1595 for treatment of Alzheimer's disease and other diseases of the CNS. This is part of the foundational patent suite supporting our all-important neuroinflammation franchise. The patent runs through 2033. In September, we announced the issuance of the U.S. patent covering INKmune as primes NK cells and its role in combating malignancy. This patent runs through 2036. I can promise you we have much more IP in the wings, and we will announce those as they are made public. I now turn it back to David Moss, INmune Bio's CFO, to discuss financial results and upcoming announcements.

Thank you, RJ. I'll provide a brief overview of our financial results and upcoming milestones. Net loss attributable to common stockholders for the second quarter ended September 30, 2020, was approximately $4.7 million compared to approximately $3.1 million for the quarter ended September 30, 2019. Research and development expenses totaled $2.4 million for the third quarter ended September 30, 2020, compared with approximately $1.2 million for the quarter ended September 30, 2019. The primary reason for the increase in loss was an increase in R&D activities related to our clinical programs, as RJ outlined. General and administrative expenses were approximately $2.5 million for the quarter ended September 30, 2020, compared to $1.9 million for the quarter ended September 30, 2019. At September 30, 2020, the company had cash and cash equivalents of approximately $24.3 million with no debt. This figure includes the closing of a public offering of common stock in July that raised gross proceeds of $25 million and net proceeds of approximately $23.1 million after deducting underwriting discounts and commissions and other offering expenses payable by the company. As of November 5, 2020, the company had approximately 13.4 million shares of common stock outstanding and preferred stock. Now I'd like to move on to a list of our upcoming milestones and catalysts. Before the year-end, as RJ had mentioned, we plan to initiate enrollment of patients with Quellor for the treatment of complications of COVID-19 infection. In January, we plan to report additional data on the Phase Ib XPro1595 in Alzheimer's disease. The company will host another KOL call in tandem with this announcement. Midyear 2021, we plan to initiate a Phase II trial of XPro1595 in treatment resistant depression that is partially funded by a $2.9 million National Institutes of Mental Health grant. Also midyear 2021, we plan to initiate a Phase II program for Alzheimer's disease with XPro1595 and in patients with neuroinflammation. In addition, assuming the clinical landscape has not changed, we are planning trials in our other programs once the COVID-19 pandemic has been controlled and our trial sites give us the go-ahead. These include enrolling our INKmune Phase I program for the treatment of ovarian cancer; enrolling patients in the INKmune Phase I trial in high risk MDS; LIVNate Phase II program for the treatment of NASH; and finally, INB03 Phase II for treatment of MUC4 resistant metastatic cancers. So in summary, notwithstanding the pandemic, we believe we are making good progress, particularly in our neuroinflammation franchise following the very compelling data that we reported in July. At this point, I'd like to thank you for your time and your attention. I'd like to turn it back to the operator for Q&A.

The first question is from Jonathan Aschoff with ROTH Capital Partners.

Thank you. RJ, at the next data release, will you release any new biomarkers that will be in addition to what you released at the first interim look?

Yes, we are working hard to expand the biomarker set. We think it's important to do that. I don’t want to promise it at this point, but we are certainly planning to expand the biomarker set. We hope to begin to get people comfortable that this concept of measuring white matter free water as a biomarker of neuroinflammation correlates well with the kinds of things they're more used to seeing like cytokine measurements in the CSF, etc.

RJ, what's the sort of other biomarkers that make you have to work so hard?

It's just a matter of getting them analyzed. That's all. I mean, when we did this study from a cost-control point of view, we batched all the studies. The plan was to do them once. Because things are moving relatively quickly, we have had to change that process. And it's just - this isn't - you don't - it's not like dialing up and ordering a hamburger. There's a considerable amount of planning because of the way the specimens are stored, etc. So it takes time and resources.

What do you think of the Biogen plan documents? And what could that potentially mean?

Well, I'm not going to comment on Biogen's aducanumab data, but I am going to say that I am fascinated and quite encouraged by the FDA's response here. My view is - and this is pretty simple. I think the FDA has decided that Alzheimer's disease is a lethal disease. It's currently the seventh most common cause of death, and that might be an underestimation. But the fact is it's a lethal disease. Historically, I think they've used a drug development set of hurdles that are more consistent with the quality of life disease, aiming for perfection. I think what they clearly signaled is that they are now going to approach this the way they approach lethal diseases like oncology. They accept less than perfection. In other words, their goal is to have more therapies for a patient tomorrow than they have today. They understand that the first products that come to market aren't going to be perfect. They're going to have worse results, but they're certainly going to be better than no product. They also know that the second product is going to be better than the first, and the third product is going to be better than the second. So I think the FDA, by finally acknowledging that Alzheimer's disease is a lethal disease, they are able to change the mindset to allow the development to look more like oncology than asthma, for instance, where, I mean, to get an asthma drug approved, you really have to have a perfect drug. You all know to get a cancer drug approved, you don’t have to have a perfect drug; you just have to make a difference at the bedside.

Did you know if fractography was used in any of the Biogen patients?

To my knowledge, they did not. I do know that AMITA, which is the CRO that we are working with, has a very close relationship with Biogen. It’s on the website, and obviously, I'm not privy to what that relationship is. I think fractography is kind of the future for CNS. I mean, we’ve got this funny view that neurology is gray matter disease. In fact, there’s a lot going on in the white matter, and we all need to learn about it. I think we're farther along than most, and it provides us with a set of tools that really give us a little bit.

And then lastly, the MUC4 trial. I believe you used to speak about MUC4 breast cancer. Did that all of a sudden morph to MUC4 cancer? Or is that always the case?

No. Actually, I've always mentioned breast cancer and other cancers because I like the MUC4 story. If you look at gastric cancer, HER2-positive gastric cancers express MUC4; pancreatic cancers express MUC4, and TKIs have a role in some of these diseases. We believe that MUC4, which is a very easy biomarker to measure, is just an immunohistochemistry. It’s combinations - potentially with INB03 and something else, whether it be Herceptin or the Herceptin-based combination therapies or TKIs is the way forward. We'll make a decision based on the work we're doing. Right now, we’ve got great data that suggests we should move forward in breast cancer. But I’ll be honest with you, Jon, you know how hard it is to succeed in breast cancer. They require big trials that take a lot of time. We’re a small company. There might be some better contexts for us to do our drug development, but it will be based on MUC4 expression. I can promise you that.

Next question is from Tom Shrader with BTIG.

This is Julian on for Tom. I actually had another question in the wake of briefing documents. I was wondering if you could talk about the relationship between XPro1595's mechanism and amyloid, and where there may be some overlap in effects and key differences.

Yes. Thank you very much. We have some very strong opinions here. Many of you are familiar with and have spoken with CJ Barnam, who’s the head of our neuroscience programs. So a lot of what I am saying really is from him. But we believe that inflammation causes the expression of amyloid. Then amyloid actually promotes inflammation. So you get this positive feedback. Actually, it's negative because of the pathology. So if you don’t have neuroinflammation, the chance of expressing the amyloid is low. Once you get amyloid, you get more inflammation, which causes more expression of it, and you get this forward cycle. So our corporate opinion is that neuroinflammation is an important part of the pathophysiology in patients with Alzheimer's disease that have amyloid. We don't - we actually believe that like most complex diseases, Alzheimer's disease will ultimately need to be treated with some kind of combination therapy. You could easily see the combination therapy that targets neuroinflammation like XPro and combine it with a drug that's trying to get rid of the cause of the inflammation, which would be an antibody trying to get rid of amyloid. We think that we are thrilled that it looks like aducanumab is moving forward because we think it's great for the space. We think it's a tremendous opportunity for XPro1595, either as a monotherapy because neuroinflammation is part of this disease complex or even as part of a combination with drugs such as aducanumab.

And then on treatment resistant depression, I was curious how far the NIH grant gets you through proof-of-concept development. And what kind of signals would support further development in this direction?

We think that it basically funds a majority of the Phase II trial. We think that, as you know, we are big fans of using biomarkers. The people we’re working with have been pioneers in the use of biomarkers in treatment-resistant depression. We think that this will set us up to move forward. If we get the kind of results that we are expecting, we would transition quickly, assuming things go well with what discussions we have to have with the regulatory agencies to a potential registration trial. It’s the same drug. It doesn’t require anything special. We just need to hone the patient selection criteria and the response criteria to ensure we can achieve success when we do the trial. The endpoint is only six weeks, which is one of the beauties of depression trials. Clinical development with long endpoints is difficult for companies of our size; they’re difficult for any company. I'd rather not have to do long-term trials. So we like depression. We think that it's a significant unmet need, but we are approaching it like we do everything with biomarkers and are going after the patients whose mechanism, their disease pathology aligns with our mechanism of action.

Next question is from Jason McCarthy with Maxim Group.

On the Quellor trial, have you selected what regions of the U.S. that you’ll target? That center is obviously a big deal now. And also, when you consider the inclusion/exclusion criteria, how will you manage patients who are coming into the hospital, getting oxygen? Maybe they're going to get steroids. If they're that far along, they’ll get some sort of IL-6 inhibitors. Are those factors that are going to play a role in your study?

So good question. So we are in the south for the most part, which is still busy. I mean, we are beginning to look at sites in the upper Midwest, such as Michigan and Wisconsin and Salt Lake, which is the intermountain west. Things are - the legacy states, New York, Massachusetts, Washington are relatively quiet. The rest of the country is really quite active. Unfortunately, you can't call up a hospital on Monday and be enrolling patients on Friday. It takes a lot longer than that. So anyway, right now, we think we’re okay. Having said that, I think your question about patients coming into the hospital is good. The trial allows dexamethasone, as is written by the U.K. study, which is 6 milligrams a day for up to 5 to 10 days. It allows remdesivir. I will say that clinicians are not sold on either of those treatments for these patients. It does not allow for another cytokine inhibitor. So if the patient is in the standard of care, it cannot include an anti-IL-6 or anti-IL-1. For the most part, we don’t see that as a major problem because most of those trials have been on patients already in the ICU. Those patients will have already failed those trials. We are conducting trials outside of the ICU. I was very worried that the standard of care arm was a very much moving target. But I'll be honest with you, Jason, there have been so many failures out there now, I’m less worried. Unfortunately, what’s happening is even when the trials fail, they don’t necessarily stop, so they can actually cannibalize patients that could be on a new product like ours. But the fact is, so far, we don't have much that works. Hopefully, Quellor will. We are quite confident in the mechanism of action. But at the end of the day, as Chris Berman used to say on ESPN, that's why we do the study; we need to do the study and prove it. So we're underway.

Regarding the MDS study, I understand it's more relevant for next year, but in considering the patients, will this be used as first-line treatment in combination with ASO, or will it be a second-line option? If it's the latter, are you planning to focus on particular mutation types?

So they will be on - many of them will be on ASO already, and we won't stop that. So it will be actually both. It could be first line, but most of the patients will have - will be on ASO and be considered not progressing on the disease - progressing on therapy.

Next question is from Michael Irwin with Univest Security.

I have two questions for the treatment resistant depression, will expanding to the cancer and state for you probably to some regard?

Ask the question again. I didn't quite get the tenor. I'm sorry.

So for the treatment resistant depression XPro1595, if that goes well, will that expand into new original patient?

So the TRD, treatment resistant depression is one trial. That's part of the CNS franchise, right? The INB03 which is our cancer program, and LIVNate which is the NASH programs, are different programs. Really, it’s just a matter - I mean, I'm not telling any of you something you haven't heard. Virtually every company is experiencing delays in initiating trials and enrolling trials. From our perspective, we just decided to focus on Quellor, which is COVID, and our CNS franchise, which is where we have funding and where we have a very unique offering. So those are moving forward. It’s not that we don't like INB03 or LIVNate, it's just that right now, we are focusing on the programs we know we can move forward.

And for the recent for failing to reintegrate in the near to how would that affect your COVID trial?

I'm sorry. So say that again? Where are we decreasing mortality?

I'm sorry. Could you repeat that? Where are we decreasing mortality?

So our endpoint, although mortality is considered a bad outcome. If you die before 28 days, you are considered, that is a negative outcome. We’re looking at patients that enter the hospital but are not in the intensive care unit, right? It is pretty rare. It happens in the U.K. because of their medical system. But in the United States, for the most part, patients don't come into the hospital and die with COVID-19; they go to the ICU, and after some period of time as they get worse. The primary endpoint of our trial is respiratory failure. We define respiratory failure as anything with a plug. So if you need CPAP, BiPAP or need to be intubated and on mechanical ventilation, you have failed. We're enrolling patients who are hypoxic, have symptoms of respiratory distress, but aren't so bad that they are going straight to the ICU. Yes, one of the great bright spots of the COVID-19 pandemic is that the mortality rate in November 2020 is, I think, fourfold lower at least than it was in March because clinical teams have gotten much better at taking care of patients. They don’t have many more tools. They're just better at taking care of patients. So I am not concerned about that decrease in mortality because what we're focused on is does the patient's respiratory disease progress, and that's related to their cytokine storm.

There are no further questions. I'll turn the call back over to Tesi.

Okay. Well, we appreciate your attendance at this call, and we are delighted with the questions. They've been excellent questions. We will conclude today's call, and we look forward to our next quarterly update, which will be the end of the year call, scheduled for March 2021. Thank you very much.

So everyone, that does conclude our call for today. We thank you for participating, and you may now disconnect.
