Yes. Thank you, Jessica. I would also like to welcome everybody to today's earnings call. Earlier this morning, we announced our financial results for the third quarter ended September 30, 2023, in our press release and Form 10-Q. During the call today, we will walk through our third quarter 2023 and subsequent highlights, financial and operating results, as well as anticipated upcoming milestones. As Jessica noted, after the presentation, you will have the opportunity to ask questions. Let's start with a review of our third quarter 2023 and subsequent highlights. I would like to begin with our vidofludimus calcium development program in multiple sclerosis. In August, we completed enrollment of our Phase 2 CALLIPER trial of vidofludimus calcium in patients with progressive multiple sclerosis or PMS. A total of 467 adult patients with primary MS or active or non-active secondary PMS were randomized to either 45 milligram daily doses of vidofludimus calcium or placebo. Patients were enrolled at more than 70 sites in North America, Western, Central and Eastern Europe. A few months later, in October, we reported overwhelmingly positive interim data from this Phase 2 CALLIPER trial. In total, 203 patients were included in this analysis. The overall population which includes all subtypes of PMS saw a 22.4% improvement in serum neurofilament light chain or NfL for vidofludimus calcium over placebo at week 24. We believe that this is a substantial and meaningful difference in favor of vidofludimus calcium in this SPMS population. A statistically significant difference was found for serum NfL at week 24 between vidofludimus calcium and placebo with a p value of 0.01. If you look at the subtypes of progressive MS to the right, you can appreciate that this difference in NfL at week 24 was consistently shown throughout all subtypes of progressive MS. I would like to point out that we saw a 20% reduction for vidofludimus calcium versus placebo in SPMS, meaning the patients with no focal inflammation activity but disease progression. This subtype is a difficult-to-treat population with no relevant FDA approved therapies available. This slide puts our CALLIPER interim data into the perspective of historical third-party studies and the same progressive MS subtypes. On the left, we display the data for PPMS compared to the Oratorio study for ocrelizumab which showed a spread of NfL values between active and placebo at 24 weeks of 12.4%. In the CALLIPER trial, we observed an 18.8% improvement of active drug over placebo in PPMS at week 24. The results of this Phase 3 study led to approval of ocrelizumab for treatment of PPMS. In the center of the slide, you see historical data for secondary progressive MS, both for non-active and active SPMS. In comparison, vidofludimus calcium was able to show a substantial reduction of NfL in both the active and non-active populations. To our knowledge, this is the first time that such a substantial effect in NfL has been shown in non-active SPMS patients, again which is the PMS subtype with the highest unmet medical need. The right side of the slide shows comparison between our Phase 2 EMPhASIS data of vidofludimus calcium in RRMS versus our historical relapsing MS studies to complete the picture. In summary, we believe the clear separation observed for serum NfL for vidofludimus calcium over placebo in this PMS patient population represents another major step forward for what potentially could be a first-in-class Nurr1 activator for MS. This strong signal also points to a more likely positive outcome of the overall CALLIPER trial also on clinically relevant endpoints like prevention of disability worsening. In October, Dr. Robert J. Fox from Cleveland Clinic who is also the coordinating investigator of our ENSURE and CALLIPER programs, presented data from our Phase 2 EMPhASIS trial of vidofludimus calcium in RRMS, an e-poster at the Joint ECTRIMS-ACTRIMS Meeting. As a reminder, vidofludimus calcium showed an improvement in serum NfL in both treatment arms of 30 milligram and 45 milligram over placebo. Just recently, we received a notice of allowance from the USPTO for a patent covering the treatment of relapsing MS with a specific strength of vidofludimus calcium. This includes a daily dose of about 10 milligram to 45 milligram of vidofludimus calcium and other sources as well as the free acid form of the treatment for relapsing MS, also covering the 30 milligram dosage used in our ongoing twin Phase 3 ENSURE trials. The claims are expected to provide protection into 2041, unless extended further. This patent significantly bolstered the multilayered proprietary IP position we have built around our late-stage program for patients with MS. Moving to our IMU-856 program. In July, we hosted a Virtual Celiac Disease Expert Roundtable to discuss ongoing active celiac disease or OACD, a serious lifelong autoimmune disorder, and the substantial unmet need for therapeutic solutions. We were grateful and honored to have been joined for this event by renowned thought leaders from Harvard Medical School, the Mayo Clinic, and the Celiac Disease Foundation. During the roundtable, our Chief Medical Officer, Andreas, also provided an overview of IMU-856 program, including our positive Phase 1 trial results in celiac disease patients released earlier this year in May, which I will highlight again in just a moment. Also in October, we presented 2 abstracts at the United European Gastroenterology Week, UEGW 2023. My colleague, Dr. Franziska Burianek, Senior Medical Director at Immunic presented data from our positive Phase 1b clinical trial of IMU-856 in patients with celiac disease during a moderated poster session. IMU-856 is an orally available and systemically acting small molecule modulator of the target SIRT6. The trial results gathered during periods of gluten-free diet and gluten challenge demonstrated positive effects for IMU-856 over placebo in 4 key dimensions of celiac disease pathophysiology: protection of the gut architecture, improvement of patients' symptoms, biomarker response, and enhancement of nutrient absorption. IMU-856 was also observed to be safe and well tolerated in this trial. We believe that this highly encouraging data provides initial clinical proof-of-concept for an entirely new therapeutic approach to gastrointestinal disorders by promoting the regeneration of bowel architecture. Additionally, Dr. Geert D'Haens from Amsterdam University Medical Center presented data from our Phase 2 CALDOSE-1 trial of vidofludimus calcium in ulcerative colitis, or UC. As a reminder, the maintenance phase results from the CALDOSE-1 trial demonstrated statistically significant activity of vidofludimus calcium compared to placebo and reaffirm the drug's favorable safety and tolerability profile. The data validated the potential of vidofludimus calcium in UC, and other inflammatory bowel disease indications. Earlier this month, Dr. Burianek had another opportunity to present the data from our Phase 1b clinical trial of IMU-856 in patients with celiac disease and a virtual e-poster at the Association of European Celiac Societies General Assembly Conference in Athens, Greece. That concludes our summary for the third quarter 2023 and subsequent highlights. I am very happy that the scientific and clinical advancements and progress made across our different programs have been extremely positive during this year. Immunic is leveraging this momentum now in discussions with pharmaceutical companies. For IMU-856, our goal is to identify a partner who is capable of performing several therapeutic Phase 2 clinical trials. For vidofludimus calcium, the release of our very good biomarker NfL data has been an important trigger point for partnering discussions with global and regional pharma players. I would now like to hand over the call to Glenn to provide a financial overview. Glenn?

Thank you, Daniel. I will now review the financial and operating results for the third quarter ended September 30, 2023. Let me start with a review of our cash position. We ended the quarter with $59.7 million in cash and cash equivalents. With these funds, we expect to be able to fund operations into September of 2024. Regarding the operating results, R&D expenses were $19.8 million for the 3 months ended September 30, 2023 as compared to $16.5 million for the 3 months ended September 30, 2022. These costs were mainly driven by external development costs related to the ongoing clinical trials of vidofludimus calcium and personnel expenses. This was partially offset by a decrease in external development costs related to the IMU-935 and IMU-856 programs. For the 9 months ended September 30, 2023, R&D expenses were $63.9 million as compared to $50.5 million for the same period ended September 30, 2022. These costs were mainly driven by external development costs related to the ongoing clinical trials of vidofludimus calcium, IMU-856 and personnel expenses. This was partially offset by a decrease in external development costs related to the Phase 2 clinical trial of vidofludimus calcium in ulcerative colitis and the IMU-935 program. G&A expenses were $3.8 million for the 3 months ended September 30, 2023, as compared to $3.6 million for the same period ended September 30, 2022. The slight increase was spread across numerous categories. For the 9 months ended September 30, 2023, G&A expenses were $11.9 million as compared to $11.6 million for the same period ended September 30, 2022. The increase was related to an increase across numerous categories, which was partially offset by a decrease in personnel expense related to stock compensation expense. Other income was $0.8 million for the 3 months ended September 30, 2023, as compared to negative $1.1 million for the same period ended September 30, 2022. The increase was primarily attributable to a decrease in foreign exchange losses and an increase in interest income as a result of higher interest rates. This was partially offset by a decrease in R&D tax incentives as a result of less spend for clinical trials in Australia. For the 9 months ended September 30, 2023, other income was $3.8 million as compared to negative $1.8 million for the same period ended September 30, 2022. The increase was primarily attributable to an increase in interest income as a result of higher interest rates, a decrease in foreign exchange losses and the research allowance attributable for tax year 2021 from the German Federal Ministry of Finance that was received in 2023. The increase was partially offset by a decrease in R&D tax incentives as a result of less spend for clinical trials in Australia. The net loss for the 3 months ended September 30, 2023 was approximately $22.8 million or $0.51 per basic and diluted share based on approximately 44.6 million weighted average common shares outstanding, compared to a net loss of approximately $21.2 million or $0.69 per basic and diluted share based on approximately 30.6 million weighted average common shares outstanding for the same period ended September 30, 2022. Net loss for the 9 months ended September 30, 2023 was approximately $72 million or $1.63 per basic and diluted share, based on 44.2 million weighted average common shares outstanding, compared to a net loss of approximately $63.9 million or $2.16 per basic and diluted share, based on 29.7 million weighted average common shares outstanding for the same period ended September 30, 2022. With that, I will turn the call back over to Daniel for a review of our upcoming clinical milestones. Daniel?

Yes. Thank you. Thank you, Glenn. I would like to provide an update on the anticipated upcoming milestones for our clinical development programs. Our current expectation is to report top line data from our Phase 2 CALLIPER trial in progressive MS in April '25. Additionally, we expect to report an interim futility analysis of our Phase 3 ENSURE program late next year to read out the first of our identical twin Phase 3 ENSURE trials in relapsing MS at the end of 2025. As stated before, based on the strong clinical activity observed so far and vidofludimus calcium's solidly established safety and tolerability profile to date, we believe that the design of the Phase 3 ENSURE program will provide a straightforward path to potential regulatory approval in relapsing MS. If top line CALLIPER data continues to show neuroprotective effects for PMS patients, we may be able to position vidofludimus calcium as the first oral treatment for non-active secondary progressive MS as well. We also expect the drug's potential first-in-class ability to activate Nurr1 to meaningfully benefit the ongoing Phase 3 ENSURE trials in relapsing MS. This brings us to the end of our formal presentation. Jessica, please open the call for the Q&A session.

Yes. Thank you, Daniel, and also Glenn, for walking us through the third quarter and subsequent highlights as well as our upcoming value inflection points. We will now begin the question-and-answer session. And our first guest today is Caroline Pocher from Wedbush PacGrow. Caroline, please unmute yourself and go ahead.

This is Caroline on for Andreas. Thank you for taking our questions. Just a few from us. Can you provide any insight into where you are in terms of preparing for the Phase 2 trial for 856 in celiac disease? What do you anticipate the trial design would look like and the timelines for when you think you would initiate the trial?

Yes. I think as we have stated before, we have fully evaluated the data and done our homework on completion, the data packages. So this is work in progress right now. And maybe some thoughts on the trial design, likely this will be a treatment phase of 3 months of treatment in ongoing active celiac disease patients. So a trial, which also makes it possible to really conclude data for further testing down the road in pivotal trials. And more or less, that's where we are right now. We're still in the preparation process.

And then just one follow-up from us. Can you talk about how enrollment is progressing in the ENSURE program and what your target timeline is to complete enrollment?

Yes. I think, as you know, we usually don't give a rolling update on the recruitment status, but we keep currently our guidance of completion of enrollment in the way that we are able to read out the first of the ENSURE studies at the end of '25 and the second one a couple of months later. So that's all I can say.

Our next guest is Liam Hiester from Piper Sandler.

I'm asking a question on behalf of Yasmeen Rahimi. Just 2 questions. So my first one is related to the CALLIPER trial. So what type of data are you expecting to report in April 2025, and what's the bar of success expected for the readout?

That's a good question, because I think we have spoken a lot about this really strong NfL data. So, of course, we will also report NfL as a secondary readout from the study. But I think the most interesting endpoints will be the primary endpoint, which is brain volume change in patients comparing active with placebo as a primary endpoint, whole brain atrophy, maybe that's the right word for that. And another, and maybe the most important secondary endpoint is confirming disability worsening. So a change in EDSS score in a confirmed way. So that also will give us, and that's, I think, important, the ability to correlate the changes in biomarkers and clinical endpoints as well at the same time. And so that's all planned to be able to be released in April 25th.

And is there a specific bar of success that you're looking for?

Well, if you look on what's currently on the market, I think the bar is not super high here. I think we want to see a benefit on all of those endpoints. But if we more or less translate what we have seen and the NfL data set into the full data read, all that would be wonderful. And also a meaningful medical difference in disability prevention would be maybe the best thing, best win here. Specifically looking on those untreatable patient populations, so looking specifically on the secondary progressive patients without focal inflammation, without relapses, so the non-active secondary progressive population, I think any benefit here would be great. And I can't give you really hard numbers here at this point. I think the study was designed to be powered for brain atrophy benefit. So that is something we want to achieve on a statistical readout here.

And then just one more question just to build off of the previous one, well, actually, and related to that, IMU-856. Have you spoken with the FDA at all, with Phase 2 design, or is it still just in the preliminary stage?

This is a process which is ongoing right now. So, usually, what we do is we submit our IND filing and then you have written communication with the regulators on protocol design and so forth.

The next one here in the queue is Matt Kaplan from Ladenberg Thalmann.

Just wanted to focus a little bit on your business development goals you mentioned during the prepared remarks. Can you talk a little bit more about that for 856 and also 858?

Yes. Thank you, Matt, and thank you for that question. Of course, here we have several good assets and good data. So you remember this year was full of good data readouts with the celiac data, with the CALDOSE maintenance data and now with the CALLIPER data. And all of these data typically are good points to intensify discussions with companies. It's difficult to really say exactly what comes first, what is the best option. But I think what we are trying is to make sure we use the data in our active discussions to really build a level of trust and a good discussion with potential partners. And based on that, then to execute the one or the other deal. So I think the best description would be that we are building more optionality on that and to have also access to some non-dilutive financing sources to fuel the rest of the pipeline based on that.

And then you mentioned in terms of some new IP. What is that the new IP that was allowed? What does that get you in terms of exclusivity period?

Yes. I think that's a good point. So that patent runs until '38. So this is a patent which covers the dose strength and the treatment of relapsing MS. And it's covered the certain dose strengths here and would protect us until '38, plus patent term extension, but there's a potential for patent term extension there, which would then protect us until '41. No. So I mixed it up. No. I think this patent goes to '41.

No, '41 is correct.

'41 is correct. Sorry. So '41 is the right number here, but we have more things in the making, so that's why.

And then you've been characterizing the vidofludimus as well in terms of its ability to be a Nurr1 activator. What does that mean from the point of view of the drug as well?

I'm grateful for this question because it's a significant topic in the MS treatment landscape. Currently, we have effective options for treating relapses in MS and have excellent medications that reduce inflammation. However, what's lacking is a way to protect neurons from damage due to factors that are not related to focal inflammation. This is particularly relevant for patients transitioning from relapsing MS to secondary progressive MS, where we see continued disability despite treatment. Based on our findings, combined with existing literature and research from other scientific groups, we believe that Nurr1 could be a promising target, offering a protective signal for neurons independent of focal inflammation. By activating Nurr1 alongside our established DHODH inhibition, we believe this drug effectively addresses both the inflammation involved in relapsing MS and provides direct neuroprotection. Additionally, our conclusions drawn from the NfL reduction suggest that this treatment could also benefit patients with primary progressive MS and non-active secondary progressive MS, who currently have limited treatment options.

And just to be clear, this is something that is completely separate from the DHODH inhibitor and unique to vidofludimus, and not characteristic of other DHODH.

Exactly. It's not linked to DHODH. It's something which is a property of the molecule and its binding ability to both, to DHODH on one hand and to Nurr1 on the other hand. And we have published a paper earlier this year together with our academic collaborators around Daniel Merk showing that the drug directly binds. There's an ICT data there in this paper showing that the molecule is directly binding to Nurr1 and as a protein.

Thank you, Matt. Yes. Maybe to follow-up on Matt's question regarding BD. We received 2 questions here in writing via the Q&A tool, which go into a similar direction. And the first one, please describe your strategy for maintaining adequate liquidity to see these opportunities through to fruition? And the second one, great clinical results, what's the plan to raise cash? Maybe, Daniel, you can give your strategic thoughts here again.

Yes. Of course, that's an important piece to make sure we earn the fruits at the end of the day, and therefore, we think it's worth to follow different ways to fund the company for the next years. And as I said, one of the important pieces could be business development activity, partnering one of the assets or maybe even two or some territorial partnerships could also be an option. Another option is kind of non-dilutive financing, for example for project financing, and the third one could be any kind of equity financing. So I think we keep those options on the table, but also considering what's going on in the capital markets.

Thank you, Daniel. Our next live guest here is Tom Smith from Leerink Partners.

I was just wondering, is there any update on the early pipeline programs like IMU-381? And, do you have any visibility on timing for advancing this program into the clinic or when we can expect to learn more on this asset?

Yes. I think the program was initiated based on positive data we generated from the CALDOSE trial. But clearly, the company is prioritizing now the clinical programs right now for the time and resource reasons. So, we have all the preparation work ongoing, part of that completed. But clearly, the resource focus and the progress of the company is focusing on performing next steps and continuing the transfer either vidofludimus calcium and for 856 right now.

And if I could just follow-up on an earlier question. Just on the 856 celiac study, are there any specific gating factors, Daniel, that you would call out, I guess, in terms of getting that program off the ground and getting the IND cleared and starting to enroll patients there?

No. As mentioned, we are preparing a trial, that means also physically preparing the trial on the material side, so production of material for the trials and so forth. And we have also stated that our priority will be celiac disease as the first indication we're trying to look at. But it's also a little bit related to the other question we answered already today that we also think about partnering. It could make sense to also broaden development beyond celiac disease. So this is something which is also an important aspect to consider in any priorities, speed going forward, and so forth with the program. So far, this is still all in preparation, also the interaction with the regulators. And this is not just limited to the U.S. It goes also into European regulators to really make sure we have a good trial prepared. Also discussing with both our KOL network on the different aspects of having a good trial setup to make sure we read out proper data. We don't fall on our own feet here. We can learn a lot from other trials in that world of celiac disease treatment. So I think it's going forward. And as soon as we are making next steps, I think we will update the market on that.

And we have one more here who wants to be with us live, which is Mayank Mamtani from B. Riley.

Hi. This is William speaking on behalf of Mayank today. Congratulations on the impressive third quarter results. I have a question regarding your NfL data from CALLIPER. It looks excellent across all subpopulations, including the broader PMS population. I am slightly curious about the active SPMS, as the numbers seem low. How should we interpret that smaller figure? Additionally, when you finalize your results, will you examine these subpopulations to determine your strategy moving forward? Will you consider focusing on one subset for the Phase 3 trial or for potential partnerships? Are you aiming to maintain this as a PMS treatment, or are you considering a broader approach? I appreciate your insights.

Thank you for the question. It's important to discuss this. The focus is on the path to regulatory approval and how we set our priorities. We are particularly excited about the data for the non-active populations, specifically for those with primary progressive multiple sclerosis and non-active secondary progressive populations. The active populations have responded well to neurofilament light chain levels. However, in the U.S., FDA-regulated treatments primarily cover relapsing forms of multiple sclerosis. Therefore, when concentrating on U.S. treatments, we are guided by our ENSURE study. Regarding primary progressive multiple sclerosis, we will primarily engage with patients exhibiting minimal or no relapse activity. Additionally, the data you mentioned about the active patient subpopulation supports our findings from the EMPhASIS Phase 2 study. This further validates our earlier insights into the relapsing multiple sclerosis population. Moving forward, identifying the best indication for regulatory approval is crucial, and this is largely influenced by our data and the existing unmet needs. The strongest case lies in non-active secondary progressive multiple sclerosis, where no effective treatments are currently available, and our positive NfL data strengthens this perspective. Of course, we plan to review the data in April 2025 to see if we observe the same clinical signals as noted in the NfL readout.

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

Yes. Thanks, Jessica, and thank you to today's attendees for your insightful questions. In summary, with the completion of enrollment of our Phase 2 CALLIPER trial, the positive interim data from the CALLIPER trial as well as the continuation of enrollment of the ENSURE Phase 3 trial, we have continued to make tangible progress on the clinical development of vidofludimus calcium during this past quarter. As progress is made, we also expect to provide an update on our preparations for a Phase 2 clinical trial of IMU-856 in patients with ongoing active celiac disease. With that, I would like to close today's call. Thank you very much for joining, and we are happy to answer any additional questions one-on-one.

Thank you for joining Immunic's third quarter 2023 earnings call. The call has now concluded. You may now disconnect.
