RJ Tesi: Thank you, David, and thank you everyone for joining the call. As usual I will arrange my remarks to highlight the key takeaways for the third quarter and the subsequent period and include updates on our platform programs. I will start by reviewing our developments of XPro before passing it over to Mark Lowdell who will provide an update on INKmune. And then David Moss will continue conclude with a discussion of our financial results, and provide an update on upcoming and new milestones then we move to Q&A. During the third quarter, our primary focus remained enrolment of patients in the AD02. Our blinded randomized Phase 2 trial in patients with early Alzheimer's disease with information. And we focused on increasing our geographic footprint of that trial.

We had notable success on both fronts. The MHRA, the UK equivalent of the FDA approved our clinical trial application in August, five of the six sites in the UK are already screening and enrolling patients into AD02. The UK is an ideal jurisdiction to expand our Alzheimer's disease trial given it possesses one of the highest rates of Alzheimer's disease in the western world coupled with robust for profit medical research infrastructure. Re:Cognition Health, our lead vendor in the UK has five memory centers with a large Rolodex of clinical trial ready patients. This provides a ready pool of patients to screen for participation in the trial. Re:Cognition Health has a history of enrolling a large number of patients and are incentivized to find the right patients to enroll in our program.

Australia where the trial is further advanced continue to see patients who have completed the six-month blinded trial and opt into the Phase 2 open label extension program. We have also submitted regulatory dossiers to additional countries with the plan to have additional sites open soon. This leaves the US and the FDA; the FDA is the outlier here. We remain on track with the FDA to meet the conditions necessary to lift the clinical hold. We believe the hold will be lifted before the end of the year. There are two main themes from the just completed CTAD or Clinical Trials Alzheimer's Disease meeting in Boston earlier treatment and better treatments. As you can imagine, we heard a lot about the anti-amyloid therapies. Little new was presented and no matter how they cut the data.

There is no change in safety or efficacy of the various anti-amyloid products. Unsurprisingly a meta-analysis demonstrated all three drugs aducanumab, lecanemab and donanemab performed the same. This is shaping up to be an interesting marketing battle debating features, not benefit. In my opinion the desire for earlier treatments is driven by the frustrating results from anti-amyloid monotherapy. That is if the results of anti-amyloid drugs were better, there may be less talk about earlier treatments. Both of these themes the limit efficacy of anti-amyloid drugs in the early treatment play to Xpro strengths. The universe of therapies for Alzheimer's disease is expanding targeting neuroinflammation is high on everyone's list. Dr. Howard Fillit, the Chief Scientific Officer of the Alzheimer's Drug Discovery Foundation highlighted the role of inflammation in aging and cognitive decline.

In a recent Fierce biotech interviewed Dr. Fillit points out that Ed autopsy beta amyloid is present in the brains of many and elderly and individuals that have died with normal cognitive function. Only those and this is the key point only those with both amyloid and inflammation have dementia. And in other words the immune response to amyloid appears to drive nerve cell death and synaptic dysfunction that results in cognitive decline. His comments highlight our long-standing position without inflammation there's no cognitive decline in patients with amyloid pathology. Combination therapy with the anti-amyloid drugs was much discussed at CTAD but no data was presented. Once again the desire for combination therapy reflects the frustration with the current results.

Combination therapies excuse me must improve safety or efficacy, ideally both because the major safety problem with anti-amyloid class of drugs is neuroinflammation we believe Xpro plays a role in combination therapy. INmune Bio has initiated preclinical studies testing combination therapy and amyloid in animal models. I emphasize the combination therapy is preclinical and in no way dilutes our focus on the Phase II trial currently enrolling patients. The discussion on early diagnosis focused on blood test aiming to produce a simple accurate cost-effective triage system. Our view is simple. Cognitive decline is predicted by biomarkers of neuroinflammation neurodegeneration, blood amyloid is a biomarker of disease, the disease of Alzheimer's, disease staging, by staging.

I mean the severity of the disease requires a different set of biomarkers. In my opinion and many of those at the meeting the most promising Duo is GFAP was Glial Fibrillary Acidic Protein at biomarker of Astra site activation and phospho-tau T217 a biomarker of neurodegeneration are promising. Although we do not use GFAB or P-tau T217 as screening biomarkers for enrollment excuse me in the Phase I trial. They were measured part as part of the biomarker response package. Both biomarkers decreased in patients after treatment house with XPro. We hope to show that this decrease correlates with clinical response in the Phase II trial. We are persistent in our belief that cognitive decline is the sum of synaptic dysfunction and nerve cell death, phospho-tau as an excellent measure of neurodegeneration or nerve cell death in patients with Alzheimer's disease.

Measuring such synaptic function is more complicated a small group of Alzheimer's patients use a self-administered EEG using the novel system from Cumulus Neuroscience. The study confirmed in the small number of patients the feasibility of collecting high quality EEG signals at home the patients liked it. And there was evidence of benefit as demonstrated by cute and chronic changes in the P300 amplitude on EEG after treatment with XPro. All the group is small and the data are early. We believe this work is further evidence of improved and synaptic function after extra treatment, and future work will correlate this activity with cognitive function and pharmacodynamic responses to the NTNS. This type of home testing may be a key element two CNS drug development in the future.

Two other applications of the DN-TNF family of drugs are worth mentioning. New data using MBO3 to treat cancer will be presented at the 38th Annual Society for Immunotherapy Meeting in San Diego later this week. MBO3 has been shown to be an checkpoint inhibitors that down regulars SIRP Alpha. SIRP Alpha that is SIRP Alpha is Signal Regulatory Protein Alpha that is the macro phase side of the CD47 don't eat me signal down regulation of SIRP Alpha Repolarized as immunosuppressive macrophages in the tumour micro environment into M2 macrophages that directly kill and phagocytosis tumours and improves ADCP which is Antibody Dependent Cellular Cytotoxicity a key but often ignored effector of anticancer antibody therapy. Recent data from the DMD program confirms the potency of the 10 keloid on pSar DN-TNF in mouse models of the disease.

As a reminder the pSar DN-TNF compounds are the sons of Xpro with similar biologic activity that allows INmune Bio to expand applications of the DN-TNF class of compounds beyond CNS. The goal of the MBO3 cancer program in the DMD program is to out-license these promising drugs. Somewhere you are wondering how a single drug dominant negative TNF inhibitor can be useful in the treatment of cancer and the treatment of Alzheimer's disease. Macrophage function is the glue that holds the story together. Microglia are tissue-based macrophages of the brain TAM's or Tumour Activated Macrophages are tissue-based macrophages in the TME of cancer. And disease chronic inflammation shall we say stuns the macrophages into not working in the brain chronic neuroinflammation causes the microglia to become a dysfunctional phenotype that produces destructive cytokine does not phagocytize cellular a mile and debris and does not prune synapses appropriately.

This results in nerve cell loss demyelination and synaptic dysfunction the hallmarks of neurodegenerative disease including Alzheimer's. DN-TNF converts the destructive microglia phenotype interoperative cell type that promotes nerve cell survival demyelination synaptic plasticity. The remodelling repair we have seen in the brains of patients with Alzheimer's disease treated with XPro reflect the normalization of microglial function caused by XPro. In cancer soluble TNF produced by tumour cells causes expression of Mach4 SIRP Alpha and other immunosuppressive cytokine the polarized amps to an immunosuppressive phenotype that promotes and protects tumour growth and metastasis. These elements promote also promote resistance to immunotherapy. XPro neutralizes soluble TNF resulting in M2 macrophages that do not express SIRP Alpha kill tumour cells promote ADCP.

On the tumour extra downregulate much forward to expose the tumour to immune attack. In summary XPpro improves the function of innate immune cells needed to defeat the ravages of neurodegenerative diseases of the brain and cancer and the macrophage is the common denominator to these effects. I will now pass this to Mark Lowdell, the founder and CSO of INmune Bio to update the progress on the INKmune program. Mark?

Mark Lowdell: Thank you very much, RJ. And once again, I'd like to pass my thanks to those that are listening in and joining this third-quarter report. So as from the last quarter report, we filed an IND with the FDA in April this year for a US trial of INKmune in metastatic castration resistant prostate cancer. We received subsequent clearance in May, for the use of INKmune in a Phase 1 Phase 2 open label trial across multiple US centers. And the response since then from potential clinical sites has really been overwhelming. We have eight sites already selected to participate in the trial. The first two sites will be initiated within two weeks' time, in November meaning that we are ahead of schedule for the planned first patient treatment, before the end of the year.

The other sites will come online in the first quarter of 2024. Most importantly, the batch of INKmune has already been manufactured for the treatment of the first US cohort and is just about to be shipped to amplify via the US distribution center. Patients at each dose level will receive all three doses of INKmune, as an outpatient treatment during the six months trial this is really critical to our future development of the drug. Two types of INKmune efficacy will be measured, immunological efficiency and therapeutic efficacy. Immunologic efficacy will measure the increase in these memory-like NK cells for the INKmune generates in the blood of the patient and how long those cells remain in the patient's blood after treatment, just as we have done in the MDS patients in the Laurel drug.

Therapeutic efficacy will measure tumour response to immune therapy using biomarkers of prostate cancer tumour burden, such as changes in blood PSA level PMSA scan and circulating tumour DNA. In addition, traditional measures of disease progression will be measured including progression free survival, changes in resist criteria using CT scan and bone scans. But as you might imagine, these are not expected to change in such a short six-month study. In the UK and Europe, we managed to advance the Laurel trial in MDS and AML. I'm sure you would be you've shared us with us this extreme frustration in the lack of recruitment in the UK to that trial. And this has been due to the changes in the clinical management of these patients in the UK in the new what we like to call post COVID era, and as a man who got COVID for the first time in August we're planning not post-COVID.

And a meeting of the trial safety committee held earlier this year. The enrollment safety criteria was modified in attempt to limit screening failures. A protocol amendment was submitted to the MHRA back in May and filing was approved last week. So we've submitted the revised protocol to the two UK clinical sites for immediate initiation and the largest cancer center in the UK The Royal Marsden Hospital has just come online and will be initiated soon. Meanwhile, the complexities of importing immune into grease for the Greek trial and establishing local laboratory monitoring of patients have all been resolved over the summer, and the first batch of drug is ready to be delivered to the hospital in Athens. A patient has completed screening and is going to be reviewed on the 3rd of November for a determination finally of suitability for inclusion and treatment.

So we hope to close the first cohort with that patient. We remain very excited about the potential of the immune platform as it begins its transition into the treatment of solid tumors. And I remind you, those are the tumors that account for approximately 90% of human cancer. For reasons we understand, most cell therapies currently focus on that 10% of cancers that are hematological tumors. But our confidence in the use of INKmune solid tumors is based on good biology. In vitro data in solid tumors from my lab shows that immune arms natural killer cells to override the immunosuppression of hypoxia and regulatory cells in the solid -- in the tumor microenvironment of solid tumors. The company presented the data on the INKmune-driven memory-like NK cells in the Presidential Symposium at the Annual Conference of the International Society of Cell & Gene Therapy in June.

And we continue to follow up those data to study INKmune NK cells at the molecular level. You'll hear more on this in the future. In my previous role as Director of the Cell & Gene Therapy facility at the [indiscernible] University College London, I spent over 30 years producing cell therapies for academic and small spin-out company clinical trials. When these are therapies attempted to enter the commercial world, many failed due to manufacturing issues. As I'm sure you know from the CAR-T story, manufacturing of cell therapies is difficult to do at scale. But we've solved that problem with a robust and scalable process for INKmune. We've been successful in upscaling the manufacturing process and have completed the validation of that new process to CGMP.

We've since signed a contract with a commercial contract manufacturing site, and the installation of equipment for that site has now started. So we're ready to move out into a commercial manufacturing setting. This investment paves the way for our ambitious plans for trials in other solid tumors, including ovarian, renal and nasopharyngeal cancer as we acquire more and more and more of the relevant supporting data. The company remains committed to execute on its vision of moving INKmune forward towards commercialization. That ends my update on the INKmune platform, and I'd like to turn the call over to David Moss, CFO, to discuss the financials. Thank you, David.

David Moss: Super, thank you, Mark. I'll provide a brief overview of our financial results and upcoming milestones before we head to the Q&A session. Net loss attributable to common stockholders for the quarter ended September 30th, 2023 was approximately $8.6 million compared with approximately $7.7 million for the comparable period in 2022. Research and development expense totaled approximately $6 billion for the quarter ended September 30th, 2023 compared with approximately $5.2 million for the comparable period in 2022. General and administrative expense was approximately $2.6 million for the quarter ended September 30th, 2023 compared with approximately $2.4 million for the comparable period in 2022. At September 30th, 2023, the company had cash and cash equivalents of approximately $41.8 million.

Based our current operating plan we believe cash is sufficient to fund our operations into late 2024. As of November 1st, 2023, the company had approximately 18 million shares of common stock outstanding. As highlighted in the prior quarter's Investor Call we continue to focus on achieving our primary clinical trial objectives or remaining cost prudent with the potential recover a portion of R&D expenses in Australia and in the UK. Now, I'd like to move on to their list of upcoming and important milestones. First milestone that we have which is we hope to have before year end is the removal of the FDA hold. Second, we expect some topline results from our Phase 2 early AD program towards the end of 2024. Upon release of the FDA hold we'll initiate a Phase 2 trial of XPro in patients with Treatment-Resistant Depression.

Additional open-label Phase 1 data of INKmune in high-risk MDS and AML in 2024 and the initiation of a Phase 1/2 program in metastatic castration resistant prostate cancer. With the first patient treated before year end and open label data in 2024. We expect an upcoming webinar on the use of XPro remyelination in neurodegenerative disease. And finally, wearing my business development hat for a moment. The DMD market with inconsistent results in gene therapy and confirmatory trials for access skipping drug still long underway is confusing. We feel that XPro could be a novel solution to replace corticosteroids in DMD. Corticosteroids, including one approved last week, target the same glucocorticoid receptor pathway and have the same immunologic metabolic and cosmetic side effects and paradoxically cause muscle atrophy.

Targeting soluble TNF with DN-TNF prevents inflammation and muscle degeneration and promote muscle regeneration in animal models without evidence of off-target safety issues seen with the use of corticosteroids or non-selective TNF inhibitors. Interestingly TNF is overexpressed in DMD at early stages of the disease where inflammation induces muscle degradation. Because corticosteroids are the most common drug used to treat DMD, a strategy that provides the benefit of corticosteroids without the side effects will benefit all patients with DMD regardless of age, stage of disease, or concomitant therapy. This is what excites us about the DN-TNF platform for DMD. As always, I think our shareholders understand that we continue to pursue business development partnership opportunities for DN-TNF in DMD and potentially other applications, but there can be no assurance that the company can complete any of these transactions if they're complex and difficult.

In summary, management feels that the company has two great platforms and as a small organization with limited resources we will tried to expand the applications of these platforms in order to benefit shareholders. Naturally, we'll update investors should material business development events occur. At this point, I'd like to thank you for your time and attention. I'd like to turn it back to Claudia to poll for questions. Claudia?
