We undertake no obligation to update or revise the information provided on this call or in the accompanying presentation as a result of new information or future results or developments. So with that, I'll turn the call over to Dan. Speaker 200:01:51Thanks, Alex. Good morning, everyone, and thanks for joining us today. I came in 2024 from a position of strength stemming from our positive results for Sibronotug in our INTERCEPT AD Phase one study in early Alzheimer's patients. In INTERCEPT AD, Sibronotug was well tolerated, demonstrated novel target engagement of A beta oligomers and produced consistent effects on imaging and flu biomarkers in a dose dependent manner. I'm proud, though not surprised, that our talented team leaned into this momentum and executed on our enrollment plans for ALTITUDE AD, our Phase II study designed to evaluate the clinical efficacy and safety of subirnatug in patients with MCI or mild dementia due to Alzheimer's, also known as early AD. Speaker 200:02:38Last year, our team worked effectively to advance the subirnatug story. And we believe this underpinned the swift pace of enrollment seen in Altitude. We engaged with the research community who recognized and embraced the novelty of Subernatrug's mechanism of action targeting toxic A beta oligomers. We also engaged with experienced clinical investigators and trial sites who appreciate the consistency of the Phase one results with this mechanism and who also recognize subirnatog's potential as a next generation treatment for early AD based on an improved benefit to risk profile. We dosed the first patient in ALTITUDE in May of twenty twenty four and just yesterday announced the completion of enrollment of five forty two participants in the study. Speaker 200:03:24This clinical enrollment milestone is a key catalyst for our subunitud program. This accomplishment also provides convincing evidence of our team's ability to operationalize and exceed enrollment goals for this sizable multinational Phase II trial. The study's primary endpoint is a change from baseline to eighteen months on the Integrated Alzheimer's Disease Rating Scale or IDRIS, which measures cognition and activities of daily living such as performing common household tasks, engaging in hobbies and conversing about current events. We've also incorporated the CDR Summit boxes and other typically used secondary measures, including imaging and fluid biomarkers. With enrollment now complete, we expect to top line results in late twenty twenty six inclusive of the key efficacy and safety measures. Speaker 200:04:13We also recently completed our Phase one study investigating a subcutaneous administration of subunitub. This was a pharmacokinetic comparison study comparing subcutaneous and intravenous administrations of Subrinatug in healthy volunteers. We believe a potential subcutaneous formulation of Subrinatug alongside the IV formulation will create important optionality for patients and providers. For instance, in some cases, greater convenience via subcutaneous administration may be more important and advantageous, whereas more touch points provided by IV infusions may be more appropriate or preferred in other situations. Providing Siburnatug in both formats may also facilitate greater optionality around treatment and induction excuse me, treatment induction and maintenance phases. Speaker 200:05:01Importantly, results from the study showed that subcutaneous Siburnatug was well tolerated with systemic exposure supporting the continued development of this format. Our next steps for the development of subcutaneous formulation of subunitope will include ongoing formulation work and other data inputs. We remain committed to communicating the development of subornotype through presentations at medical conferences and peer reviewed publications. We've maintained a significant presence at all the major Alzheimer's conferences, ADPD, AAN, AAIC and CTAD. We will present our Phase one results at several upcoming medical meetings. Speaker 200:05:37These presentations will focus on the importance of our fluid biomarker data that showed consistent trends towards normalization after only three doses in the study. I'm very pleased to note as well that our INTERCEPT AD Phase one manuscript was published in the Journal of the Prevention of Alzheimer's Disease or JPAD in January 2025. In addition, a related publication detailing the fluid biomarker changes in that study was also published online in JPAD just last month. You can find both publications online at the journal and linked on our website. Next week at ADPD, we will also present the use of a plasma PTOW217 assay as a screening procedure in altitude AD, our ongoing Phase II study. Speaker 200:06:23The use of this screening assay considerably improved enrollment efficiency and decreased patient burden and cost in the screening process. Feedback on the use of this PTOW217 assay has been very positive as evidenced by the rapid pace of our Phase II enrollment. Utilization of fluid biomarkers in this way is a prime example of innovation in the Alzheimer's space and a clear indication of how fluid biomarkers will continue to advance the field from diagnostic, treatment and development perspectives. At Acumen, we are staunchly committed to our strategic goal of advancing the clinical development of SiburnaTug in a diligent and efficient manner. We are executing at a very high level as supported by all of the progress reported here today. Speaker 200:07:06We remain encouraged by the continued adoption of new Alzheimer's treatments, which we believe illustrates the large underlying demand in this growing and long underserved patient population. The fundamental elements of the Alzheimer's landscape include an aging population, more diagnosed cases driven by the increasing ability to diagnose in earlier stages of disease due to better blood based biomarkers and more treated cases due to the availability of options and continued establishment of screening and infusion capabilities for monoclonal antibodies. We believe the adoption of anti A beta treatments will continue to grow and ultimately serve as the cornerstone of AD treatment for the foreseeable future. The dynamics of this patient population also present a great opportunity for improvements with next generation anti amyloid therapies and in the future combination approaches. We believe in the promise of subveratog as a next generation treatment option for Alzheimer's patients based on an improved benefit to risk profile and are highly motivated to make an outsized impact on this devastating disease, which affects all of us in one way or another. Speaker 200:08:10I look forward to providing updates as we progress towards the ALTITUDE AD Phase II data readout next year. And with that, I'll turn the call over to Matt for the financials. Speaker 300:08:22Thank you, Dan. As a reminder, our full year 2024 financial results are available in the press release we issued this morning and in our 10 ks we'll file later today. We ended 2024 with $231,500,000 in cash and marketable securities on our balance sheet, which is expected to support our current clinical and operational activities into the first half of twenty twenty seven. R and D expenses were $93,800,000 in 2024. The increase over the prior year was primarily due to the increased spending to support the ALPTUTU AD trial, which began enrollment in May 2024. Speaker 300:09:08G and A expenses were $20,200,000 in 2024, roughly flat to the same period in the prior year. This led to a loss from operations of $114,000,000 and the net loss of $102,300,000 during the year after accounting for interest income. I'm pleased with Acumen's execution on every level as we continue to work to interrogate the promise of subunitub for the treatment of early AD. With enrollment now complete in our ALTITUDE AD Phase II trial, we look forward to sharing top line results, which are expected in late twenty twenty six and remain dedicated to delivering a potential next generation treatment option for Speaker 400:09:55for the unmet need Speaker 300:09:55in this patient population. And with that, we can open the call for Q and A. Operator? Operator00:10:00Thank Our first question comes from Jason Zemansky with Bank of America. Your line is open. Speaker 500:10:17Good morning. Congrats on the progress and thank you for taking our questions. Maybe a higher level one from us, especially now that you have the good data for the subcutaneous formulation. As the field sort of is continuing to evolve, there seems to be greater interest in looking at the anti amyloid mechanism earlier in the disease. And certainly, a number of your competitors are opening trials where they're looking at preclinical AD. Speaker 500:10:44I'm curious, is that on your landscape at all, especially now that the Phase two has completed enrollment? How does that, I guess, rank on your priorities as you move forward? Speaker 200:10:59Thanks, Jason. So right now, we are certainly focused on the execution in Altitude AD and the Surly AD population. I think we're obviously cognizant of the possibility of moving into that preclinical population, particularly as I mentioned, sort of the utility of blood based biomarkers and better profiling of patients. I think we can also envision where the mechanism of SUBERNA targeting these toxic soluble aggregates of A beta are an early and persistent part of the pathophysiology of the disease. And so an agent that's selected for these species such as Subernatog could be highly useful or valuable for that population. Speaker 200:11:39But at present, we really are focused on conduct and execution in Altitude AD. Speaker 500:11:45Got it. And then maybe just a quick follow-up. In terms of layering in the subcu formulation in Altitude AD, what are the possibilities here? Jim, do you want to jump on that one? Speaker 600:12:00Yes. Jason, this is Jim Daugherty. Happy to answer that question. Obviously, as we think about the subcutaneous formulation, it really does expand the optionality for patients. And now that we have our Phase one data in healthy volunteers, we've got some work to do around further formulation development and planning for dosing. Speaker 600:12:19But as we also do this planned, the program team is thinking about what's the best way to include further work in the Suburban Sub program. So right now, we are still working on which of those options is going to be most efficient pathway forward, but we will update you on that when we have a bit more information. But certainly the next steps are going to be designed to fit most efficiently with the ongoing IV studies in the Spernathog program. Speaker 500:12:49Got it. Thanks for the updates. Looking forward to next steps. Operator00:12:55Thank you. Our next question comes from Pete Stavropoulos with Cantor. Your line is open. Speaker 700:13:02Hi, Dan and team. Congrats on getting the ALTITUDE study fully enrolled and the subcu data. And thanks for taking my questions. First questions are, there's been a number of recent disclosures over the past year in Alzheimer's space, many of which suggest that changes in certain biomarkers start to appear far in advance of symptoms as well as the underlying pathology? And I'm sure we will get more at upcoming conferences. Speaker 700:13:30Just how do these updates inform your approach and assumptions about the disease and the clinical studies? And what are the key biomarkers that you think you may emphasize upon the data readout? And understanding that the data is in late twenty six, what do you expect to show at the top line? Speaker 200:13:48Thanks, Pete. Jim, do you want to take a first pass at that? And Pete, you're a little vague on which of these disclosures or biomarkers are of interest on EDU. Speaker 700:13:59Any of the key biomarkers that are appearing at the medical conferences? Speaker 600:14:04Yes. Happy to take that question, Pete. Obviously, there is an explosion in work going on right now across the Alzheimer's space of trying to better understand the available biochemical biomarkers. And in fact, as the technology improves and the sensitivity improves, there is almost weekly updates in this space as you're alluding to. We'll be attending the ADPD meeting in Vienna next week and I'm expecting a whole new raft of information as it comes out. Speaker 600:14:35So we very much feel that this is something that we need to stay current on and stay on top of on a pretty much regular basis because I think as time goes forward, what I'm expecting to see is with more increased precision and an increased number of biomarkers, better and better identification of individual patients, better and better segregation of patients over time. And I think that only benefits treatment. I think as far as subverted tug goes, we are investing quite a bit in including biochemical biomarkers in our study as you know. Certainly, we believe that the FOSFITALE-two 17, PTAL-two 17 is a really important marker. Eric will be presenting next week on our use of PTAL-two seventeen as a prescreening tool, but we also think that it's going to be helpful for identifying types of patients in the response. Speaker 600:15:29And I think it's also very likely to be the case that additional markers that have not yet been as well characterized or maybe even not yet identified will be important in the future. And so another feature of what we're doing with the ALTITUDE study is bio banking samples. So we have a fairly robust plan for biomarker analysis. But in addition to that, we're also going to be reserving samples with the thought that additional data and additional markers are going to be coming out over time. Speaker 400:16:00Yes. All right. Speaker 700:16:00Thank you. Speaker 800:16:01And maybe if I could just briefly add something to that. Pete, I think you had sort of two questions embedded in there. One, as far as altitude, just to remind you that the primary outcome measure is the ITRIS. So it's a clinical cognitive and functional measure. So based on the strength of our Phase one data, ALTITUDE, you can really think of as a it's a Phase 2b registration quality study. Speaker 800:16:29So we the primary outcome is the IGRESS. Now as you've heard, we're spending a lot of time looking at biomarkers and we think those are very important. I think the other part of your question was which biomarkers happened before any clinical symptoms, which gets you into the preclinical space. And again, that's a topic of conversation for the field. Right now, we're just focused primarily on ALTITUDE and Subburnitide along with the subcutaneous formulation. Speaker 100:17:05Jim and Dan, I don't think you if one of you want us to respond to Pete on his question about what would be involved in the top line? Speaker 600:17:17Yes. So Pete, certainly as Eric was just saying, the primary analysis, the primary endpoint for the study is address. And so when we talk about top line, although we haven't disclosed the full list of what is going to be available at top line, we're certainly expecting the clinical endpoints to be available at top line and we're working on our plan for biochemical biomarkers. I wouldn't expect all of that information to necessarily be available when we have the initial top line, the initial clinical readouts, but we will certainly have a plan to get those additional endpoints out as quickly as possible. And you'll hear more from us as time goes forward on the exact timing for various pieces to add to the top line. Speaker 700:18:03All right. Thank you very much for taking my questions and congrats again on full enrollments in the subcu data. Speaker 900:18:10Thank you. Speaker 200:18:11Thanks, Steve. Operator00:18:14Thank you. Our next question comes from Ting Liu with UBS. Your line is open. Speaker 400:18:20Good morning. And this is Ting from Chong's team. Congrats on the recent progress and thanks for taking our question. Could you elaborate a bit more on the use of p Tau217 fluid biomarker during patient screening for the Phase two? If all patients have positive p Tau217, how would that translate to top pathology if to detect by TAL pad? Speaker 400:18:45And should we consider patients enrolled to altitude AD baseline kind of resemble to dolanumab Phase III trial? Thank you. Speaker 200:18:56Thanks, Tim. Eric, why don't you you're planning to cover that one. Speaker 800:19:00Yes. So thanks for the question. It really is an active area of research right now. So the part of your question was how PTOW217 will relate to tau PET, which is a very good question. But because of the characteristics of PTOW217 and the screening process, we actually use that as a way of screening for being amyloid positive and that being amyloid positive could be based on either PET or spinal fluid. Speaker 800:19:30So what we've found and we'll present this again at ADPD next week, is that as a screening tool, plasma PTOW217 works very, very well. And we'll present the numbers on that, but it decreases the number of say negative PET scans by about half. There's a big a little bit of a debate in the field right now about could plasma PTAL217 completely replace PET scans or CSF. My personal opinion is I'm not sure it's quite to that point, but I do think it works very, very well as a screener before you get either PET or CSF. And I think that could be translated actually to clinical practice. Speaker 800:20:19So thanks for the question. Speaker 400:20:23Yes. Thanks, Aaron. Operator00:20:28Thank you. Our next question comes from Tom Schroeder with BTIG. Your line is open. Speaker 900:20:35Good morning. Thanks for taking the questions. Really a couple of thought questions. Most of the work on sub Q antibodies has been after plaque removal and you have an antibody that may not remove plaque. How are you thinking about that? Speaker 900:20:49Do you hope biomarkers will be validated enough to carry the game by the time you're ready? Or do you have some ideas on how you might actually get efficacy data from a subcu formulation? And then probably an Eric question, iAddress versus CDR sum of boxes, what's the difference in your mind is I think every antibody that's worked and has measured both has hit for both. Just why one over the other? Is there any real advantage to I address you can have us think about? Speaker 900:21:18Thank you. Speaker 200:21:25Jim, do you want to grab the Yes, Speaker 800:21:27I can grab the IDRIS first and then we can go back. So yes, you're right. In the Phase III studies, if you hit on the CDR soma boxes, you also hit on the IDRIS. In our view, there's less subjectivity and less variability with the IDRIS compared to the CDR soma boxes, but there are some similarities. But I might just point out that in the Phase II study of denanimab that Lilly did, they did reach statistical significance on the Idris, but they actually missed statistical significance on the CDR soma boxes. Speaker 800:22:05So I think that's a good example of Idris actually is a less variable, less subjective scale. Speaker 600:22:13Yes, Tom. And when it comes to the MOA for Subernatog and the focus on soluble ligaments rather than Plaques. Now I think at the end of the day, of course, as Eric was just saying around the clinical endpoints, really the cognitive endpoints understanding effects on ADLs is really what's going to be most critically important. We as you know from the INTERCEPT study, we do see some effects of Sibbernatog on plaques and not surprising because of course the plaques are a complex dynamic environment, there's sidewall ligma decorating around plaques. And so I think that piece of the story is yet to be completely told and that's part of what we're going to get out of altitude two d. Speaker 600:22:55But I think being able to sequester those soluble lignumors, we feel and of course this is the hypothesis for testing that that combination of effects is going to have a meaningful effect on cognitive performance and perhaps even on the ADL side. And so that's what we're looking for. We'll tell the story of effects on plaques and how much that's relevant to the overall effect as we get the data in from Altitude. And we'll be well positioned to do that between the imaging data, the biochemical data and perhaps most importantly the cognitive endpoints. Speaker 900:23:30Great. Thank you very much. Operator00:23:47Our next question comes from Paul Matteis with Stifel. Your line is open. Speaker 200:23:53Hey, this is Julian on for Paul. Thanks so much for taking our question and congrats on the progress. I guess just really quickly anything else you can say about enrollment? Obviously, it's ahead of schedule, but any color around what gives you confidence you have the right patients for this trial would be helpful. And then just really quickly, if you could share anything else on subQ, did the results come in line with your expectations or was anything unusual? Speaker 200:24:23Would be grateful to hear. Thanks so much. Speaker 600:24:26Yes. Julian, thanks for the questions. So I think the first question around enrollment, we're very confident that we've got the appropriate patients enrolled in the study between Speaker 400:24:37there Speaker 600:24:37are a large number of disease modification studies that have been running over the past years and our team is certainly very well aware of those studies and Eric has been involved in quite a number of studies on his own. And really, I think we've got the appropriate entry criteria to select the right patients for the study in this early AD space. So we're very happy, we're certainly very happy to be enrolled. The full study was enrolled in less than a year in about ten months' time. But even more importantly at high quality sites and we think we've got the right patient populations. Speaker 600:25:12As time goes forward, we'll be telling you a little bit more about the baseline characteristics of the population that's included in ALTITUDE. To your second question around the subcutaneous data, really at this point, I would say we're very pleased with the study and I don't think there were that many surprises. What in the major conclusion is we're not seeing any new safety signals. The major adverse event that we saw was somewhat expected around injection site reactions. We did see a fairly high fraction of injection site reactions at sixty two point five percent, but importantly, they were all mild and sort of consistent with what had been seen previously with this type of COMIX. Speaker 600:25:55And then on the PK side, we're seeing exposure levels that are consistent with further development and that's really I think the best way to say it at this point. We do and we have quite a bit more work to do. This is in healthy volunteers. We've got work to do around looking at concentrations and all those sorts of things. And so that's the kind of work that the team will be doing moving forward. Speaker 600:26:18But we're happy today to be talking about taking next steps with the subcutaneous formulation and having the exposure from that study that we think we need to work with to move the program forward. Speaker 800:26:30Yes. And maybe if I could just add one quick thing about the patient population, because it came up in a previous question. If you compare the denanumab studies with the ritonumab studies, for the Lilly Trailblazer studies because they had a tau requirement, those people if you look at baseline characteristics are always a little bit worse than the people in the lecanumab studies. Our population certainly for INTERCEPT, the Phase one study looked really very similar to the lecanumab population because we did not have a TOW requirement. So it looked similar to lecanumab. Speaker 800:27:15And again, we just finished enrollment, but looking at the baseline data so far, the patient population for altitude looks very similar to the patient population for INTERCEPT. But I think the important thing is the dasanumab studies are a little bit of an outlier because they have a tower requirement. Speaker 200:27:37Thanks so much for the color. Operator00:27:41Thank you. And our next question comes from Ananda Ghosh with H. C. Wainwright and Company. Your line is open. Speaker 1000:27:49Hi, Dan and Tim. Thanks for the question. One of the might be a macro question. By the time the Altitude AD completes, there will be plasma biomarkers, which will be approved by FDA probably sometime this year. There will be new data coming from the BrainShetl based antibodies. Speaker 1000:28:08And we'll probably know more about the A beta immunotherapy adoption scenario across U. S. And other ex U. S. Countries. Speaker 1000:28:17So with those in the background, how are you thinking about positioning SabrinaTag as the altitude AD approaches to completion? Speaker 200:28:30Sure. So, Ananda, thanks for the question. I think at a very high level, we envision Sverntag reading out late next year as a differentiated highly differentiated next generation treatment option will be timely for all of those elements that you described, including the continued adoption of anti A beta treatments that where there is recognizable room for improvement in terms of a risk benefit profile and where other blood based biomarkers will continue to enable the appropriate diagnosis and presumably adoption of further products for this underserved population. So we're excited to have as Jim mentioned, I mean, we enrolled ALTITUDE AD in roughly ten months, pretty sizable five forty two patient study. And now to be looking at reading that out next year in an environment where there's more optimism and enthusiasm for addressing this unmet need is really exciting to us. Speaker 200:29:32So it looks like a great setup. Speaker 1000:29:37Thanks. Operator00:29:41Thank you. I'm showing no further questions at this time. I'd like to turn the call back over to Alex Braun for closing remarks. Speaker 100:29:48Great. Thanks, Michelle. And thank you to everyone for listening today and for your interest in Acumen. If you have any further questions, we're always available at the company. All right. Speaker 100:29:58Thanks. Have a great day. Operator00:30:02Thank you for your participation.

There are 11 speakers on the call. Operator00:00:00Good day, and welcome to the Acumen Pharma Fiscal Year twenty twenty four Conference Call and Webcast. At this time, all participants are in a listen only mode. After this presentation, there will be a question and answer session. Instructions will be given at that time. As a reminder, this call may be recorded. Operator00:00:16I would now like to turn the call over to Alex Braun, Head of Investor Relations. Please go ahead. Speaker 100:00:22Thanks, Michelle. Good morning, and welcome to the Acumen conference call to discuss our business update and financial results for the year ended 12/31/2024. With me today are Dan O'Connell, our CEO and Matt Zuga, our CFO and Chief Business Officer. Matt and Dan have some prepared remarks and then we'll open the call for questions. Joining for the Q and A session, we also have Doctor. Speaker 100:00:45Jim Doherty, our President and Chief Development Officer and Doctor. Eric Siemers, our Chief Medical Officer. Before we begin, we encourage listeners to go to the Investors section of the Acumen website to find our press release issued this morning that we'll discuss today. Please note that during today's conference call, we may make forward looking statements within the meaning of the federal securities laws, including statements concerning our financial outlook and expected business plans. These statements are subject to risks and uncertainties that could cause actual results to differ materially from those described in the forward looking statements. Speaker 100:01:19Please see Slide two of our corporate presentation, our press release issued this morning and our most recent annual and quarterly reports filed with the SEC for important risk factors that could cause our actual results to differ materially from those expressed or implied in the forward looking statements. We undertake no obligation to update or revise the information provided on this call or in the accompanying presentation as a result of new information or future results or developments. So with that, I'll turn the call over to Dan. Speaker 200:01:51Thanks, Alex. Good morning, everyone, and thanks for joining us today. I came in 2024 from a position of strength stemming from our positive results for Sibronotug in our INTERCEPT AD Phase one study in early Alzheimer's patients. In INTERCEPT AD, Sibronotug was well tolerated, demonstrated novel target engagement of A beta oligomers and produced consistent effects on imaging and flu biomarkers in a dose dependent manner. I'm proud, though not surprised, that our talented team leaned into this momentum and executed on our enrollment plans for ALTITUDE AD, our Phase II study designed to evaluate the clinical efficacy and safety of subirnatug in patients with MCI or mild dementia due to Alzheimer's, also known as early AD. Speaker 200:02:38Last year, our team worked effectively to advance the subirnatug story. And we believe this underpinned the swift pace of enrollment seen in Altitude. We engaged with the research community who recognized and embraced the novelty of Subernatrug's mechanism of action targeting toxic A beta oligomers. We also engaged with experienced clinical investigators and trial sites who appreciate the consistency of the Phase one results with this mechanism and who also recognize subirnatog's potential as a next generation treatment for early AD based on an improved benefit to risk profile. We dosed the first patient in ALTITUDE in May of twenty twenty four and just yesterday announced the completion of enrollment of five forty two participants in the study. Speaker 200:03:24This clinical enrollment milestone is a key catalyst for our subunitud program. This accomplishment also provides convincing evidence of our team's ability to operationalize and exceed enrollment goals for this sizable multinational Phase II trial. The study's primary endpoint is a change from baseline to eighteen months on the Integrated Alzheimer's Disease Rating Scale or IDRIS, which measures cognition and activities of daily living such as performing common household tasks, engaging in hobbies and conversing about current events. We've also incorporated the CDR Summit boxes and other typically used secondary measures, including imaging and fluid biomarkers. With enrollment now complete, we expect to top line results in late twenty twenty six inclusive of the key efficacy and safety measures. Speaker 200:04:13We also recently completed our Phase one study investigating a subcutaneous administration of subunitub. This was a pharmacokinetic comparison study comparing subcutaneous and intravenous administrations of Subrinatug in healthy volunteers. We believe a potential subcutaneous formulation of Subrinatug alongside the IV formulation will create important optionality for patients and providers. For instance, in some cases, greater convenience via subcutaneous administration may be more important and advantageous, whereas more touch points provided by IV infusions may be more appropriate or preferred in other situations. Providing Siburnatug in both formats may also facilitate greater optionality around treatment and induction excuse me, treatment induction and maintenance phases. Speaker 200:05:01Importantly, results from the study showed that subcutaneous Siburnatug was well tolerated with systemic exposure supporting the continued development of this format. Our next steps for the development of subcutaneous formulation of subunitope will include ongoing formulation work and other data inputs. We remain committed to communicating the development of subornotype through presentations at medical conferences and peer reviewed publications. We've maintained a significant presence at all the major Alzheimer's conferences, ADPD, AAN, AAIC and CTAD. We will present our Phase one results at several upcoming medical meetings. Speaker 200:05:37These presentations will focus on the importance of our fluid biomarker data that showed consistent trends towards normalization after only three doses in the study. I'm very pleased to note as well that our INTERCEPT AD Phase one manuscript was published in the Journal of the Prevention of Alzheimer's Disease or JPAD in January 2025. In addition, a related publication detailing the fluid biomarker changes in that study was also published online in JPAD just last month. You can find both publications online at the journal and linked on our website. Next week at ADPD, we will also present the use of a plasma PTOW217 assay as a screening procedure in altitude AD, our ongoing Phase II study. Speaker 200:06:23The use of this screening assay considerably improved enrollment efficiency and decreased patient burden and cost in the screening process. Feedback on the use of this PTOW217 assay has been very positive as evidenced by the rapid pace of our Phase II enrollment. Utilization of fluid biomarkers in this way is a prime example of innovation in the Alzheimer's space and a clear indication of how fluid biomarkers will continue to advance the field from diagnostic, treatment and development perspectives. At Acumen, we are staunchly committed to our strategic goal of advancing the clinical development of SiburnaTug in a diligent and efficient manner. We are executing at a very high level as supported by all of the progress reported here today. Speaker 200:07:06We remain encouraged by the continued adoption of new Alzheimer's treatments, which we believe illustrates the large underlying demand in this growing and long underserved patient population. The fundamental elements of the Alzheimer's landscape include an aging population, more diagnosed cases driven by the increasing ability to diagnose in earlier stages of disease due to better blood based biomarkers and more treated cases due to the availability of options and continued establishment of screening and infusion capabilities for monoclonal antibodies. We believe the adoption of anti A beta treatments will continue to grow and ultimately serve as the cornerstone of AD treatment for the foreseeable future. The dynamics of this patient population also present a great opportunity for improvements with next generation anti amyloid therapies and in the future combination approaches. We believe in the promise of subveratog as a next generation treatment option for Alzheimer's patients based on an improved benefit to risk profile and are highly motivated to make an outsized impact on this devastating disease, which affects all of us in one way or another. Speaker 200:08:10I look forward to providing updates as we progress towards the ALTITUDE AD Phase II data readout next year. And with that, I'll turn the call over to Matt for the financials. Speaker 300:08:22Thank you, Dan. As a reminder, our full year 2024 financial results are available in the press release we issued this morning and in our 10 ks we'll file later today. We ended 2024 with $231,500,000 in cash and marketable securities on our balance sheet, which is expected to support our current clinical and operational activities into the first half of twenty twenty seven. R and D expenses were $93,800,000 in 2024. The increase over the prior year was primarily due to the increased spending to support the ALPTUTU AD trial, which began enrollment in May 2024. Speaker 300:09:08G and A expenses were $20,200,000 in 2024, roughly flat to the same period in the prior year. This led to a loss from operations of $114,000,000 and the net loss of $102,300,000 during the year after accounting for interest income. I'm pleased with Acumen's execution on every level as we continue to work to interrogate the promise of subunitub for the treatment of early AD. With enrollment now complete in our ALTITUDE AD Phase II trial, we look forward to sharing top line results, which are expected in late twenty twenty six and remain dedicated to delivering a potential next generation treatment option for Speaker 400:09:55for the unmet need Speaker 300:09:55in this patient population. And with that, we can open the call for Q and A. Operator? Operator00:10:00Thank Our first question comes from Jason Zemansky with Bank of America. Your line is open. Speaker 500:10:17Good morning. Congrats on the progress and thank you for taking our questions. Maybe a higher level one from us, especially now that you have the good data for the subcutaneous formulation. As the field sort of is continuing to evolve, there seems to be greater interest in looking at the anti amyloid mechanism earlier in the disease. And certainly, a number of your competitors are opening trials where they're looking at preclinical AD. Speaker 500:10:44I'm curious, is that on your landscape at all, especially now that the Phase two has completed enrollment? How does that, I guess, rank on your priorities as you move forward? Speaker 200:10:59Thanks, Jason. So right now, we are certainly focused on the execution in Altitude AD and the Surly AD population. I think we're obviously cognizant of the possibility of moving into that preclinical population, particularly as I mentioned, sort of the utility of blood based biomarkers and better profiling of patients. I think we can also envision where the mechanism of SUBERNA targeting these toxic soluble aggregates of A beta are an early and persistent part of the pathophysiology of the disease. And so an agent that's selected for these species such as Subernatog could be highly useful or valuable for that population. Speaker 200:11:39But at present, we really are focused on conduct and execution in Altitude AD. Speaker 500:11:45Got it. And then maybe just a quick follow-up. In terms of layering in the subcu formulation in Altitude AD, what are the possibilities here? Jim, do you want to jump on that one? Speaker 600:12:00Yes. Jason, this is Jim Daugherty. Happy to answer that question. Obviously, as we think about the subcutaneous formulation, it really does expand the optionality for patients. And now that we have our Phase one data in healthy volunteers, we've got some work to do around further formulation development and planning for dosing. Speaker 600:12:19But as we also do this planned, the program team is thinking about what's the best way to include further work in the Suburban Sub program. So right now, we are still working on which of those options is going to be most efficient pathway forward, but we will update you on that when we have a bit more information. But certainly the next steps are going to be designed to fit most efficiently with the ongoing IV studies in the Spernathog program. Speaker 500:12:49Got it. Thanks for the updates. Looking forward to next steps. Operator00:12:55Thank you. Our next question comes from Pete Stavropoulos with Cantor. Your line is open. Speaker 700:13:02Hi, Dan and team. Congrats on getting the ALTITUDE study fully enrolled and the subcu data. And thanks for taking my questions. First questions are, there's been a number of recent disclosures over the past year in Alzheimer's space, many of which suggest that changes in certain biomarkers start to appear far in advance of symptoms as well as the underlying pathology? And I'm sure we will get more at upcoming conferences. Speaker 700:13:30Just how do these updates inform your approach and assumptions about the disease and the clinical studies? And what are the key biomarkers that you think you may emphasize upon the data readout? And understanding that the data is in late twenty six, what do you expect to show at the top line? Speaker 200:13:48Thanks, Pete. Jim, do you want to take a first pass at that? And Pete, you're a little vague on which of these disclosures or biomarkers are of interest on EDU. Speaker 700:13:59Any of the key biomarkers that are appearing at the medical conferences? Speaker 600:14:04Yes. Happy to take that question, Pete. Obviously, there is an explosion in work going on right now across the Alzheimer's space of trying to better understand the available biochemical biomarkers. And in fact, as the technology improves and the sensitivity improves, there is almost weekly updates in this space as you're alluding to. We'll be attending the ADPD meeting in Vienna next week and I'm expecting a whole new raft of information as it comes out. Speaker 600:14:35So we very much feel that this is something that we need to stay current on and stay on top of on a pretty much regular basis because I think as time goes forward, what I'm expecting to see is with more increased precision and an increased number of biomarkers, better and better identification of individual patients, better and better segregation of patients over time. And I think that only benefits treatment. I think as far as subverted tug goes, we are investing quite a bit in including biochemical biomarkers in our study as you know. Certainly, we believe that the FOSFITALE-two 17, PTAL-two 17 is a really important marker. Eric will be presenting next week on our use of PTAL-two seventeen as a prescreening tool, but we also think that it's going to be helpful for identifying types of patients in the response. Speaker 600:15:29And I think it's also very likely to be the case that additional markers that have not yet been as well characterized or maybe even not yet identified will be important in the future. And so another feature of what we're doing with the ALTITUDE study is bio banking samples. So we have a fairly robust plan for biomarker analysis. But in addition to that, we're also going to be reserving samples with the thought that additional data and additional markers are going to be coming out over time. Speaker 400:16:00Yes. All right. Speaker 700:16:00Thank you. Speaker 800:16:01And maybe if I could just briefly add something to that. Pete, I think you had sort of two questions embedded in there. One, as far as altitude, just to remind you that the primary outcome measure is the ITRIS. So it's a clinical cognitive and functional measure. So based on the strength of our Phase one data, ALTITUDE, you can really think of as a it's a Phase 2b registration quality study. Speaker 800:16:29So we the primary outcome is the IGRESS. Now as you've heard, we're spending a lot of time looking at biomarkers and we think those are very important. I think the other part of your question was which biomarkers happened before any clinical symptoms, which gets you into the preclinical space. And again, that's a topic of conversation for the field. Right now, we're just focused primarily on ALTITUDE and Subburnitide along with the subcutaneous formulation. Speaker 100:17:05Jim and Dan, I don't think you if one of you want us to respond to Pete on his question about what would be involved in the top line? Speaker 600:17:17Yes. So Pete, certainly as Eric was just saying, the primary analysis, the primary endpoint for the study is address. And so when we talk about top line, although we haven't disclosed the full list of what is going to be available at top line, we're certainly expecting the clinical endpoints to be available at top line and we're working on our plan for biochemical biomarkers. I wouldn't expect all of that information to necessarily be available when we have the initial top line, the initial clinical readouts, but we will certainly have a plan to get those additional endpoints out as quickly as possible. And you'll hear more from us as time goes forward on the exact timing for various pieces to add to the top line. Speaker 700:18:03All right. Thank you very much for taking my questions and congrats again on full enrollments in the subcu data. Speaker 900:18:10Thank you. Speaker 200:18:11Thanks, Steve. Operator00:18:14Thank you. Our next question comes from Ting Liu with UBS. Your line is open. Speaker 400:18:20Good morning. And this is Ting from Chong's team. Congrats on the recent progress and thanks for taking our question. Could you elaborate a bit more on the use of p Tau217 fluid biomarker during patient screening for the Phase two? If all patients have positive p Tau217, how would that translate to top pathology if to detect by TAL pad? Speaker 400:18:45And should we consider patients enrolled to altitude AD baseline kind of resemble to dolanumab Phase III trial? Thank you. Speaker 200:18:56Thanks, Tim. Eric, why don't you you're planning to cover that one. Speaker 800:19:00Yes. So thanks for the question. It really is an active area of research right now. So the part of your question was how PTOW217 will relate to tau PET, which is a very good question. But because of the characteristics of PTOW217 and the screening process, we actually use that as a way of screening for being amyloid positive and that being amyloid positive could be based on either PET or spinal fluid. Speaker 800:19:30So what we've found and we'll present this again at ADPD next week, is that as a screening tool, plasma PTOW217 works very, very well. And we'll present the numbers on that, but it decreases the number of say negative PET scans by about half. There's a big a little bit of a debate in the field right now about could plasma PTAL217 completely replace PET scans or CSF. My personal opinion is I'm not sure it's quite to that point, but I do think it works very, very well as a screener before you get either PET or CSF. And I think that could be translated actually to clinical practice. Speaker 800:20:19So thanks for the question. Speaker 400:20:23Yes. Thanks, Aaron. Operator00:20:28Thank you. Our next question comes from Tom Schroeder with BTIG. Your line is open. Speaker 900:20:35Good morning. Thanks for taking the questions. Really a couple of thought questions. Most of the work on sub Q antibodies has been after plaque removal and you have an antibody that may not remove plaque. How are you thinking about that? Speaker 900:20:49Do you hope biomarkers will be validated enough to carry the game by the time you're ready? Or do you have some ideas on how you might actually get efficacy data from a subcu formulation? And then probably an Eric question, iAddress versus CDR sum of boxes, what's the difference in your mind is I think every antibody that's worked and has measured both has hit for both. Just why one over the other? Is there any real advantage to I address you can have us think about? Speaker 900:21:18Thank you. Speaker 200:21:25Jim, do you want to grab the Yes, Speaker 800:21:27I can grab the IDRIS first and then we can go back. So yes, you're right. In the Phase III studies, if you hit on the CDR soma boxes, you also hit on the IDRIS. In our view, there's less subjectivity and less variability with the IDRIS compared to the CDR soma boxes, but there are some similarities. But I might just point out that in the Phase II study of denanimab that Lilly did, they did reach statistical significance on the Idris, but they actually missed statistical significance on the CDR soma boxes. Speaker 800:22:05So I think that's a good example of Idris actually is a less variable, less subjective scale. Speaker 600:22:13Yes, Tom. And when it comes to the MOA for Subernatog and the focus on soluble ligaments rather than Plaques. Now I think at the end of the day, of course, as Eric was just saying around the clinical endpoints, really the cognitive endpoints understanding effects on ADLs is really what's going to be most critically important. We as you know from the INTERCEPT study, we do see some effects of Sibbernatog on plaques and not surprising because of course the plaques are a complex dynamic environment, there's sidewall ligma decorating around plaques. And so I think that piece of the story is yet to be completely told and that's part of what we're going to get out of altitude two d. Speaker 600:22:55But I think being able to sequester those soluble lignumors, we feel and of course this is the hypothesis for testing that that combination of effects is going to have a meaningful effect on cognitive performance and perhaps even on the ADL side. And so that's what we're looking for. We'll tell the story of effects on plaques and how much that's relevant to the overall effect as we get the data in from Altitude. And we'll be well positioned to do that between the imaging data, the biochemical data and perhaps most importantly the cognitive endpoints. Speaker 900:23:30Great. Thank you very much. Operator00:23:47Our next question comes from Paul Matteis with Stifel. Your line is open. Speaker 200:23:53Hey, this is Julian on for Paul. Thanks so much for taking our question and congrats on the progress. I guess just really quickly anything else you can say about enrollment? Obviously, it's ahead of schedule, but any color around what gives you confidence you have the right patients for this trial would be helpful. And then just really quickly, if you could share anything else on subQ, did the results come in line with your expectations or was anything unusual? Speaker 200:24:23Would be grateful to hear. Thanks so much. Speaker 600:24:26Yes. Julian, thanks for the questions. So I think the first question around enrollment, we're very confident that we've got the appropriate patients enrolled in the study between Speaker 400:24:37there Speaker 600:24:37are a large number of disease modification studies that have been running over the past years and our team is certainly very well aware of those studies and Eric has been involved in quite a number of studies on his own. And really, I think we've got the appropriate entry criteria to select the right patients for the study in this early AD space. So we're very happy, we're certainly very happy to be enrolled. The full study was enrolled in less than a year in about ten months' time. But even more importantly at high quality sites and we think we've got the right patient populations. Speaker 600:25:12As time goes forward, we'll be telling you a little bit more about the baseline characteristics of the population that's included in ALTITUDE. To your second question around the subcutaneous data, really at this point, I would say we're very pleased with the study and I don't think there were that many surprises. What in the major conclusion is we're not seeing any new safety signals. The major adverse event that we saw was somewhat expected around injection site reactions. We did see a fairly high fraction of injection site reactions at sixty two point five percent, but importantly, they were all mild and sort of consistent with what had been seen previously with this type of COMIX. Speaker 600:25:55And then on the PK side, we're seeing exposure levels that are consistent with further development and that's really I think the best way to say it at this point. We do and we have quite a bit more work to do. This is in healthy volunteers. We've got work to do around looking at concentrations and all those sorts of things. And so that's the kind of work that the team will be doing moving forward. Speaker 600:26:18But we're happy today to be talking about taking next steps with the subcutaneous formulation and having the exposure from that study that we think we need to work with to move the program forward. Speaker 800:26:30Yes. And maybe if I could just add one quick thing about the patient population, because it came up in a previous question. If you compare the denanumab studies with the ritonumab studies, for the Lilly Trailblazer studies because they had a tau requirement, those people if you look at baseline characteristics are always a little bit worse than the people in the lecanumab studies. Our population certainly for INTERCEPT, the Phase one study looked really very similar to the lecanumab population because we did not have a TOW requirement. So it looked similar to lecanumab. Speaker 800:27:15And again, we just finished enrollment, but looking at the baseline data so far, the patient population for altitude looks very similar to the patient population for INTERCEPT. But I think the important thing is the dasanumab studies are a little bit of an outlier because they have a tower requirement. Speaker 200:27:37Thanks so much for the color. Operator00:27:41Thank you. And our next question comes from Ananda Ghosh with H. C. Wainwright and Company. Your line is open. Speaker 1000:27:49Hi, Dan and Tim. Thanks for the question. One of the might be a macro question. By the time the Altitude AD completes, there will be plasma biomarkers, which will be approved by FDA probably sometime this year. There will be new data coming from the BrainShetl based antibodies. Speaker 1000:28:08And we'll probably know more about the A beta immunotherapy adoption scenario across U. S. And other ex U. S. Countries. Speaker 1000:28:17So with those in the background, how are you thinking about positioning SabrinaTag as the altitude AD approaches to completion? Speaker 200:28:30Sure. So, Ananda, thanks for the question. I think at a very high level, we envision Sverntag reading out late next year as a differentiated highly differentiated next generation treatment option will be timely for all of those elements that you described, including the continued adoption of anti A beta treatments that where there is recognizable room for improvement in terms of a risk benefit profile and where other blood based biomarkers will continue to enable the appropriate diagnosis and presumably adoption of further products for this underserved population. So we're excited to have as Jim mentioned, I mean, we enrolled ALTITUDE AD in roughly ten months, pretty sizable five forty two patient study. And now to be looking at reading that out next year in an environment where there's more optimism and enthusiasm for addressing this unmet need is really exciting to us. Speaker 200:29:32So it looks like a great setup. Speaker 1000:29:37Thanks. Operator00:29:41Thank you. I'm showing no further questions at this time. I'd like to turn the call back over to Alex Braun for closing remarks. Speaker 100:29:48Great. Thanks, Michelle. And thank you to everyone for listening today and for your interest in Acumen. If you have any further questions, we're always available at the company. All right. Speaker 100:29:58Thanks. Have a great day. Operator00:30:02Thank you for your participation. You may now disconnect. Everyone have a great day.Read morePowered by
