Welcome to the Acumen Pharmaceuticals Q1 twenty twenty five Conference Call and Webcast. At this time, all participants are in a listen only mode. Please be advised that today's conference is being recorded. After the speakers' presentation, there will be a question and answer session. Operator00:00:27I would now like to hand the conference over to your speaker today, Alex Braun, Head of Investor Relations. Alex BraunVP & Head of Investor Relations at Acumen Pharmaceuticals00:00:34Thanks, Josh. Good morning, and welcome to the Acumen conference call to discuss our business update and financial results for the quarter ended 03/31/2025. With me today are Dan O'Connell, our CEO, and Matt Zuga, our CFO and Chief Business Officer. Dan and Matt have some prepared remarks, and then we'll open the call for questions. Joining for the q and a session, we also have doctor Jim Dougherty, our president and chief development officer and doctor Eric Siemers, our chief medical officer. Alex BraunVP & Head of Investor Relations at Acumen Pharmaceuticals00:01:05Before 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. Please 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. Alex BraunVP & Head of Investor Relations at Acumen Pharmaceuticals00:01:59So with that, I'll turn the call over to Dan. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:02:03Great, thanks Alex. Good morning everyone and thanks for joining us today. As we noted in our year end call in late March, Acumen continues to build momentum towards our goal of establishing Suburbanitug as a next generation treatment option for patients with mild cognitive impairment or mild dementia known as early Alzheimer's disease or early AD. In the first quarter, we completed enrollment of our five forty two participant phase two study, ALTITUDE AD, which is designed to evaluate the clinical efficacy and safety of sabernatog in patients with early AD. We completed enrollment of ALTITUDE in roughly ten months, much faster than expected. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:02:42We attribute the rapid pace of enrollment to the interest in cibernitug therapeutic potential as supported by an extensive non clinical dataset and positive phase one results, innovative participant screening methods used in the trial, and strong execution by our team and clinical partners. We expect top line results for ALTI2D AD in late twenty twenty six, inclusive of the key efficacy and safety measures. In April, we presented at two major Alzheimer's medical conferences, ADPD and AAN. Consistent with the rapidly growing focus on the utility of fluid biomarkers in AD, our presentations highlighted an innovative use of a plasma phospho tau217 screening procedure in altitude AD. Our study, combined with multiple recent clinical investigations, support the use of plasma pTau217 as a sensitive indicator of the presence of amyloid pathology. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:03:44Our objective for the pTau217 screen was to reduce the number of negative PET scans, thereby streamlining the screening process. In our INTERCEPT phase one study, only forty percent of individuals screened for participation in the study tested positive on amyloid PET. In comparison, by screening for a specific threshold of pTau217 in altitude prior to a PET scan, eighty one percent of screened individuals that met or exceeded the threshold tested positive on amyloid PET, a significant improvement. The use of the PITO217 screening assay improved enrollment efficiency, decreased patient burden, and reduced screening costs in Altitude. We believe this approach contributed to our very rapid enrollment rate and serves as a clear example of how we consistently implement innovative approaches to AD drug development based on insights and emerging data from the field. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:04:43Building off the INTERCEPT manuscript and biomarker changes that published in Q1 in the Journal for the Prevention of Alzheimer's Disease at ADPD and AAN, we also presented posters detailing other innovations our team has made to deepen the conversation around cibernitug's therapeutic potential. These innovations include insights into the early effects of cibernitug on synaptic biomarkers in AD, methods to develop abeta ligand selective assays, and a non clinical model to test more precisely the interactions between sabranitug and abeta ligaments that better replicates the human brain environment. Methods posters like these are important as they align with our view that A beta oligomers are the most toxic form of amyloid in the Alzheimer's brain and thus advancements to such assays and tools can help inform oligomer preference of selective drugs like sabermatog. As communicated on our year end call, during the first quarter we also completed a phase one study investigating subcutaneous administration of Subrinitug, comparing subcutaneous and intravenous administration of Subrinitug in healthy volunteers. Importantly, results from the study showed that Suburbanipug was well tolerated with systemic exposure supporting the continued development of this route of administration. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:06:01Our next steps for the development of Suburbanipug for subcutaneous administration involve ongoing formulation drug delivery assessments. We are confident in sabernatog as an innovative and differentiated potential treatment for people with Alzheimer's disease. Our team is driven each day by the opportunity to make a difference in the fight against this devastating disease. We continue to execute to establish Subirantuck's therapeutic potential and are excited to be on track to share the Phase II results late next year. And with that, I'll turn the call over to Matt for the financials. Matthew ZugaCFO & Chief Business Officer at Acumen Pharmaceuticals00:06:35Thank you, Dan. As a reminder, our first quarter twenty twenty five financial results are available in the press release we issued this morning and in our 10 Q we will file later today. As of March 31, we had $197,900,000 in cash and marketable securities on our balance sheet, which is expected to support our current clinical and operational activities into early twenty twenty seven. R and D expenses were $25,300,000 in the first quarter. The increase over the prior year was primarily due to the increased spending to support the ALPITUDE AD trial, which completed enrollment in March 2025. Matthew ZugaCFO & Chief Business Officer at Acumen Pharmaceuticals00:07:22G and A expenses were $5,100,000 in the quarter, roughly flat to the same period in the prior year. This led to a loss from operations of $30,400,000 and a net loss of $28,800,000 in the quarter. We are off to a strong start with Altitude AD and we look forward to sharing top line results which are expected in late twenty twenty six. We remain dedicated to delivering a potential next generation treatment option for the benefit of patients, caregivers and shareholders. And with that, we can open the call for Q and A. Operator? Operator00:08:01Thank you. Our first question comes from Paul Matisse with Stifel. You may proceed. Analyst00:08:22Hi, this is Matthew for Paul. Thanks for taking our question and congrats on the progress. So a quick question on the SubQ. Once the formulation and drug delivery assessments are complete, how or when are you thinking about incorporating that into your future development plans? Thank you. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:08:42Thanks, Matthew. And then we've got Jim and Eric on the call. I'm going to direct that one to Jim initially to provide comment. Jim DohertyPresident & Chief Development Officer at Acumen Pharmaceuticals00:08:49Thanks, Dan, and hi, Matthew. Yeah, so your question is, as we get to next stages in our understanding of the subcu development, how do we integrate it into the program? And I think there's a couple of options that we have in front of us. And the team is working very hard on establishing what's going be the most efficient pathway. And I think basically the major options would include incorporating an arm of sub q administration into an ongoing phase three study for IV Suburbanipug that's planned based on outcomes from the ALPITUDE AD IV study. Jim DohertyPresident & Chief Development Officer at Acumen Pharmaceuticals00:09:27Or alternatively doing a standalone study looking at the effects of SubQ Suburbanipug to be able to compare to the program. So those are the two major pathways, and at this time the team is still evaluating what's going to be the most efficient path forward. Ultimately, that's our goal, to be able to most rapidly and effectively evaluate both opportunities for patients. Thank you. Operator00:09:52Thank you. Our next question comes from Pete Stavaropoulos with Cantor Fitzgerald. You may proceed. Sarah MedeirosBioPharma & Biotech Equity Research Associate at Cantor Fitzgerald00:10:03Hi, this is Sarah Medeiros on for Pete. We have a couple of questions. The first question being, can you just remind us the powering assumptions for ALPITUDE and if there is an interim and futility look built into the study? Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:10:18Sure, Eric, you want to quickly hit on that? Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:10:21Yeah, sure. So we do not have an interim analysis in the study. Initially, there was some discussion about that possibility, but we made the decision not to do an interim analysis. There's really no need to do that. And in terms of the powering, we haven't disclosed any specific numbers, but I can just tell you that the powering is very appropriate for a phase two study. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:10:47It's five forty two people, so it's not a small phase two. It's actually a fairly good sized phase two study, but the powering is appropriate for a Phase II study. Sarah MedeirosBioPharma & Biotech Equity Research Associate at Cantor Fitzgerald00:11:03Great. And just a quick follow-up. There's been a lot of progress in the Alzheimer's space, many of which show that changes in biomarkers start to appear far in advance of symptoms, as well as some of the underlying pathology, like various cow species. How do these updates inform your approach and assumptions about the disease and clinical studies? And understanding that the data is in late twenty twenty six, what do you expect to show at the top line? Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:11:31Well, thanks. That's a great question, because the field's just made a lot of advances recently, especially in terms of these blood based plasma biomarkers, which five years ago probably people wouldn't have thought that was possible, but we're starting to see that now. But what we did in our development plan for spironolactide is even in our Phase I study, we did that in patients, and we had a number of different biomarkers in the study. And interestingly, even in the MAD cohorts, the multiple dose cohorts, where they still only got three administrations of the drug, we saw changes in these biomarkers that people are now looking at pretty commonly. So whether it's and not everything was statistically significant because it was a little phase one study, but directionally it was very consistent. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:12:31So we had normalization of the A beta forty two over 40 ratio, which correlates with the amount of amyloid plaque. We had decreases in different p tau species. We had directional changes in a biomarker called GFAP, which is an astrocyte marker. So we had all these different things, even in our own phase one study with just three administrations of drug go the right direction essentially. So the field is really moving rapidly. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:13:08There at this point, I think it's safe to say that there's not a broadly accepted surrogate biomarker for Alzheimer's disease. So you still need clinical outcomes to have approval. It is our general expectation. And by the way, our phase two study, primary outcome is the clinical measure, the scale called the IDRIS. But these biomarkers really give you really a good indication of central pharmacology. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:13:45And I think we've talked about this before, but we were just very pleased to see that even in a phase one study that we had evidence of central pharmacology of sabernatog in patients with Alzheimer's disease. So it's really nice for somebody like myself who's been in the field for quite a while to see these really rapid advances, many of which are based on these biomarkers that people are now better understanding and we now have the technology, the tools to measure them better. Jim DohertyPresident & Chief Development Officer at Acumen Pharmaceuticals00:14:19And maybe just to amplify a little bit on what Eric's saying, as you can hear, we think a lot about biomarkers and including biomarkers in our trials, as do most of the field So as Eric was saying, there's been a tremendous amount of advancement in the last few years building off a long history of trying to address these issues. And I think you can see that progress is being made in understanding how to stage Alzheimer's patients as they move through this progressive disorder. And also, types of biomarkers may inform mechanism of action kind of question. So we've put some emphasis on synaptic biomarkers that could be measures of underlying synaptic health and activity. Jim DohertyPresident & Chief Development Officer at Acumen Pharmaceuticals00:15:02So we do think that by the time we're looking at readout from ALPITUDE AD, there's going to be a lot of value in biomarkers as context to add to the primary endpoint, which as Eric rightly points out, are the cognitive endpoints. But there's a richness to the data that these biomarkers are bringing, and so for us we think it's going be an important part of the story. And in addition to the markers that we're currently measuring, we're also careful to do plasma sampling to allow us to do additional work as the field continues to learn. Sarah MedeirosBioPharma & Biotech Equity Research Associate at Cantor Fitzgerald00:15:35Great. Thank you. Operator00:15:38Thank you. Our next question comes from Tom Schrader with BTIG. You may proceed. Thomas ShraderMD & Healthcare Analyst at BTIG00:15:47Good morning. Thanks for taking the questions fairly related to the last questioner. But as it seems like the commercial antibodies are getting some traction and two companies are working very hard. Are you finding that that poses any risk to your trial? Is your dropout rate about where you thought it would be given you had a placebo given you have a placebo arm and then I have a mechanistic follow-up. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:16:13Yeah, good question. Go ahead Eric. Sure. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:16:17Well, okay. Yeah, so no, it's a good it's a great question and it's something that we've thought about quite a bit is because there now are two FDA approved drugs, at least in The United States, could that be a risk to our study? And so far that's just not been the case, and as you know the launch of both of those drugs with lucanumab being a little soon having a little more history to it now has been relatively slow, a lot of that we think is due to just infrastructure not being present and it'll continue to be built. But the bottom line is for our ALDITUDE study, you know again as Dan mentioned previously, the enrollment rate was much higher than we had actually projected. So we enrolled you know five forty two people in ten months, which is pretty substantial. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:17:16But then in terms of discontinuation rates, know this is an ongoing blinded trial and we finished enrollment you know a relatively short period of time ago, but so far the discontinuation rate looks looks quite good. So we're not seeing problems with these marketed drugs. One of the things to keep in mind is that we do have an open label extension at the end of the study, so people who get randomized into altitude, so it's a three arm study, one arm is placebo, so chances are two out of three that you're not on placebo, and then when you get to the open label extension a hundred percent of people will be on drug. So we think that's one of the study design aspects that's really made this an attractive study for people and so far the studies progressing, you know, very nicely. Thomas ShraderMD & Healthcare Analyst at BTIG00:18:14Okay, and then for PLOSO Tau217, and you guys are all over this marker, is this the best guess for the for a useful treatment biomarker? Or is that not likely to be the case? And do you have a sense of where we sit today? What's likely to be the best treatment biomarker? Do you think your synaptic markers that are kind of novel have a better chance? Thomas ShraderMD & Healthcare Analyst at BTIG00:18:39But where do we stand on a treatment biomarker? We understand staging biomarkers are quite advanced. Yeah, Tom, this is Jim. Happy to take that one. As I was saying, we do definitely think that these plasma based biomarkers are going to be continuing to evolve. Thomas ShraderMD & Healthcare Analyst at BTIG00:18:57And I think, as you just said, staging is one clear use, and I think that's coming along. I think markers of activity or efficacy, I think everyone is asking that question. I think at this point, we don't yet know. Certainly, pTau217 is going to be critical in whatever plays out. I think my guess and our guess is that we're likely to see a series of markers that are used to both understand where patients are in their Alzheimer's journey, but also to be used to assess ongoing cognitive I don't think we're likely to see a single marker giving a clear progressive marker of cognitive activity, you're likely to see multiple markers giving you a sense as patients continue. Thomas ShraderMD & Healthcare Analyst at BTIG00:19:52And I think beyond that we'll just have to wait and see. But that would be my guess is that we'll see a number of different markers correlating with the progression of disease and that's part of what's happening right now is there are a lot of studies ongoing trying to work out which markers at which time are correlating with function. So stay tuned. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:20:13Yeah, the interesting thing about that question is that these biomarkers can be used either for diagnostic purposes or to assess drug effects. Lot times the same biomarker can be used to do both, And so it gets a little confusing in terms of what's the purpose of your biomarker, but but you can use them either way, either as a diagnostic or as evidence of drug effect. Thomas ShraderMD & Healthcare Analyst at BTIG00:20:40Okay. Great. Thank you. Operator00:20:43Thank you. Our next question comes from Ting Lu with UBS. You may proceed. Trung HuynhExecutive Director - Equity Research at UBS Group00:20:50Good morning, and thank you for taking our question. I have a follow-up question on biomarker, maybe focusing on the synaptic biomarkers given there are increasing interest in the field on how oligomer targeted therapy may differentiate in promoting synaptic recoveries, which are not much evidenced in the plug targeted therapies yet. However, we've seen some recent data from Roche and they have shown trontinemab also meaningfully reduced synaptic biomarker like neuro granin. So can I ask what are your thoughts over the Roche's data? Also, maybe if you could talk about the overall, like, what about your updated thoughts on how competitive on the competitive position of supernatag versus trontaneumab? Thank you. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:21:52Thanks, Teng. I think Eric that kind of follows along the preview you gave of the INTERCEPT results, were short duration study, but meaningfully moving both some of the abeta tau but also the synaptic markers. I think even the VAP-two, one of the presynaptic markers achieving significance across each of the higher dose cohorts. So I think for a short duration study such as INTERCEPT, we're encouraged to think that LTT AD is certainly positioned to read out in potentially a more impactful and broader way. We'll just, we'll have to see. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:22:34I think, you know, we're now positioned to read out the study next year. So excited about that prospect. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:22:44Yeah, right. I mean, INTERCEPT may not have been the very first study to measure these synaptic biomarkers, but it was certainly one of the first. And as you point out with fructanomab now, for example, it's something that the field is looking at broadly. So we're pleased that we were one of the first studies to show effects on synaptic biomarkers, and obviously we'll look at those in our ALTITUDE study in addition. Trung HuynhExecutive Director - Equity Research at UBS Group00:23:18Thank you. Those are really helpful. Operator00:23:24Thank you. I would now like to turn the call back over to Alex Braun for any closing remarks. Alex BraunVP & Head of Investor Relations at Acumen Pharmaceuticals00:23:29Great. Thanks, Josh, and thanks, everyone, for taking the time and for joining us today. We are available at the company anytime for additional questions. And with that, I hope you all have a great day.

PresentationSkip to Participants Operator00:00:00Good day, and thank you for standing by. Welcome to the Acumen Pharmaceuticals Q1 twenty twenty five Conference Call and Webcast. At this time, all participants are in a listen only mode. Please be advised that today's conference is being recorded. After the speakers' presentation, there will be a question and answer session. Operator00:00:27I would now like to hand the conference over to your speaker today, Alex Braun, Head of Investor Relations. Alex BraunVP & Head of Investor Relations at Acumen Pharmaceuticals00:00:34Thanks, Josh. Good morning, and welcome to the Acumen conference call to discuss our business update and financial results for the quarter ended 03/31/2025. With me today are Dan O'Connell, our CEO, and Matt Zuga, our CFO and Chief Business Officer. Dan and Matt have some prepared remarks, and then we'll open the call for questions. Joining for the q and a session, we also have doctor Jim Dougherty, our president and chief development officer and doctor Eric Siemers, our chief medical officer. Alex BraunVP & Head of Investor Relations at Acumen Pharmaceuticals00:01:05Before 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. Please 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. Alex BraunVP & Head of Investor Relations at Acumen Pharmaceuticals00:01:59So with that, I'll turn the call over to Dan. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:02:03Great, thanks Alex. Good morning everyone and thanks for joining us today. As we noted in our year end call in late March, Acumen continues to build momentum towards our goal of establishing Suburbanitug as a next generation treatment option for patients with mild cognitive impairment or mild dementia known as early Alzheimer's disease or early AD. In the first quarter, we completed enrollment of our five forty two participant phase two study, ALTITUDE AD, which is designed to evaluate the clinical efficacy and safety of sabernatog in patients with early AD. We completed enrollment of ALTITUDE in roughly ten months, much faster than expected. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:02:42We attribute the rapid pace of enrollment to the interest in cibernitug therapeutic potential as supported by an extensive non clinical dataset and positive phase one results, innovative participant screening methods used in the trial, and strong execution by our team and clinical partners. We expect top line results for ALTI2D AD in late twenty twenty six, inclusive of the key efficacy and safety measures. In April, we presented at two major Alzheimer's medical conferences, ADPD and AAN. Consistent with the rapidly growing focus on the utility of fluid biomarkers in AD, our presentations highlighted an innovative use of a plasma phospho tau217 screening procedure in altitude AD. Our study, combined with multiple recent clinical investigations, support the use of plasma pTau217 as a sensitive indicator of the presence of amyloid pathology. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:03:44Our objective for the pTau217 screen was to reduce the number of negative PET scans, thereby streamlining the screening process. In our INTERCEPT phase one study, only forty percent of individuals screened for participation in the study tested positive on amyloid PET. In comparison, by screening for a specific threshold of pTau217 in altitude prior to a PET scan, eighty one percent of screened individuals that met or exceeded the threshold tested positive on amyloid PET, a significant improvement. The use of the PITO217 screening assay improved enrollment efficiency, decreased patient burden, and reduced screening costs in Altitude. We believe this approach contributed to our very rapid enrollment rate and serves as a clear example of how we consistently implement innovative approaches to AD drug development based on insights and emerging data from the field. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:04:43Building off the INTERCEPT manuscript and biomarker changes that published in Q1 in the Journal for the Prevention of Alzheimer's Disease at ADPD and AAN, we also presented posters detailing other innovations our team has made to deepen the conversation around cibernitug's therapeutic potential. These innovations include insights into the early effects of cibernitug on synaptic biomarkers in AD, methods to develop abeta ligand selective assays, and a non clinical model to test more precisely the interactions between sabranitug and abeta ligaments that better replicates the human brain environment. Methods posters like these are important as they align with our view that A beta oligomers are the most toxic form of amyloid in the Alzheimer's brain and thus advancements to such assays and tools can help inform oligomer preference of selective drugs like sabermatog. As communicated on our year end call, during the first quarter we also completed a phase one study investigating subcutaneous administration of Subrinitug, comparing subcutaneous and intravenous administration of Subrinitug in healthy volunteers. Importantly, results from the study showed that Suburbanipug was well tolerated with systemic exposure supporting the continued development of this route of administration. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:06:01Our next steps for the development of Suburbanipug for subcutaneous administration involve ongoing formulation drug delivery assessments. We are confident in sabernatog as an innovative and differentiated potential treatment for people with Alzheimer's disease. Our team is driven each day by the opportunity to make a difference in the fight against this devastating disease. We continue to execute to establish Subirantuck's therapeutic potential and are excited to be on track to share the Phase II results late next year. And with that, I'll turn the call over to Matt for the financials. Matthew ZugaCFO & Chief Business Officer at Acumen Pharmaceuticals00:06:35Thank you, Dan. As a reminder, our first quarter twenty twenty five financial results are available in the press release we issued this morning and in our 10 Q we will file later today. As of March 31, we had $197,900,000 in cash and marketable securities on our balance sheet, which is expected to support our current clinical and operational activities into early twenty twenty seven. R and D expenses were $25,300,000 in the first quarter. The increase over the prior year was primarily due to the increased spending to support the ALPITUDE AD trial, which completed enrollment in March 2025. Matthew ZugaCFO & Chief Business Officer at Acumen Pharmaceuticals00:07:22G and A expenses were $5,100,000 in the quarter, roughly flat to the same period in the prior year. This led to a loss from operations of $30,400,000 and a net loss of $28,800,000 in the quarter. We are off to a strong start with Altitude AD and we look forward to sharing top line results which are expected in late twenty twenty six. We remain dedicated to delivering a potential next generation treatment option for the benefit of patients, caregivers and shareholders. And with that, we can open the call for Q and A. Operator? Operator00:08:01Thank you. Our first question comes from Paul Matisse with Stifel. You may proceed. Analyst00:08:22Hi, this is Matthew for Paul. Thanks for taking our question and congrats on the progress. So a quick question on the SubQ. Once the formulation and drug delivery assessments are complete, how or when are you thinking about incorporating that into your future development plans? Thank you. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:08:42Thanks, Matthew. And then we've got Jim and Eric on the call. I'm going to direct that one to Jim initially to provide comment. Jim DohertyPresident & Chief Development Officer at Acumen Pharmaceuticals00:08:49Thanks, Dan, and hi, Matthew. Yeah, so your question is, as we get to next stages in our understanding of the subcu development, how do we integrate it into the program? And I think there's a couple of options that we have in front of us. And the team is working very hard on establishing what's going be the most efficient pathway. And I think basically the major options would include incorporating an arm of sub q administration into an ongoing phase three study for IV Suburbanipug that's planned based on outcomes from the ALPITUDE AD IV study. Jim DohertyPresident & Chief Development Officer at Acumen Pharmaceuticals00:09:27Or alternatively doing a standalone study looking at the effects of SubQ Suburbanipug to be able to compare to the program. So those are the two major pathways, and at this time the team is still evaluating what's going to be the most efficient path forward. Ultimately, that's our goal, to be able to most rapidly and effectively evaluate both opportunities for patients. Thank you. Operator00:09:52Thank you. Our next question comes from Pete Stavaropoulos with Cantor Fitzgerald. You may proceed. Sarah MedeirosBioPharma & Biotech Equity Research Associate at Cantor Fitzgerald00:10:03Hi, this is Sarah Medeiros on for Pete. We have a couple of questions. The first question being, can you just remind us the powering assumptions for ALPITUDE and if there is an interim and futility look built into the study? Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:10:18Sure, Eric, you want to quickly hit on that? Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:10:21Yeah, sure. So we do not have an interim analysis in the study. Initially, there was some discussion about that possibility, but we made the decision not to do an interim analysis. There's really no need to do that. And in terms of the powering, we haven't disclosed any specific numbers, but I can just tell you that the powering is very appropriate for a phase two study. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:10:47It's five forty two people, so it's not a small phase two. It's actually a fairly good sized phase two study, but the powering is appropriate for a Phase II study. Sarah MedeirosBioPharma & Biotech Equity Research Associate at Cantor Fitzgerald00:11:03Great. And just a quick follow-up. There's been a lot of progress in the Alzheimer's space, many of which show that changes in biomarkers start to appear far in advance of symptoms, as well as some of the underlying pathology, like various cow species. How do these updates inform your approach and assumptions about the disease and clinical studies? And understanding that the data is in late twenty twenty six, what do you expect to show at the top line? Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:11:31Well, thanks. That's a great question, because the field's just made a lot of advances recently, especially in terms of these blood based plasma biomarkers, which five years ago probably people wouldn't have thought that was possible, but we're starting to see that now. But what we did in our development plan for spironolactide is even in our Phase I study, we did that in patients, and we had a number of different biomarkers in the study. And interestingly, even in the MAD cohorts, the multiple dose cohorts, where they still only got three administrations of the drug, we saw changes in these biomarkers that people are now looking at pretty commonly. So whether it's and not everything was statistically significant because it was a little phase one study, but directionally it was very consistent. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:12:31So we had normalization of the A beta forty two over 40 ratio, which correlates with the amount of amyloid plaque. We had decreases in different p tau species. We had directional changes in a biomarker called GFAP, which is an astrocyte marker. So we had all these different things, even in our own phase one study with just three administrations of drug go the right direction essentially. So the field is really moving rapidly. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:13:08There at this point, I think it's safe to say that there's not a broadly accepted surrogate biomarker for Alzheimer's disease. So you still need clinical outcomes to have approval. It is our general expectation. And by the way, our phase two study, primary outcome is the clinical measure, the scale called the IDRIS. But these biomarkers really give you really a good indication of central pharmacology. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:13:45And I think we've talked about this before, but we were just very pleased to see that even in a phase one study that we had evidence of central pharmacology of sabernatog in patients with Alzheimer's disease. So it's really nice for somebody like myself who's been in the field for quite a while to see these really rapid advances, many of which are based on these biomarkers that people are now better understanding and we now have the technology, the tools to measure them better. Jim DohertyPresident & Chief Development Officer at Acumen Pharmaceuticals00:14:19And maybe just to amplify a little bit on what Eric's saying, as you can hear, we think a lot about biomarkers and including biomarkers in our trials, as do most of the field So as Eric was saying, there's been a tremendous amount of advancement in the last few years building off a long history of trying to address these issues. And I think you can see that progress is being made in understanding how to stage Alzheimer's patients as they move through this progressive disorder. And also, types of biomarkers may inform mechanism of action kind of question. So we've put some emphasis on synaptic biomarkers that could be measures of underlying synaptic health and activity. Jim DohertyPresident & Chief Development Officer at Acumen Pharmaceuticals00:15:02So we do think that by the time we're looking at readout from ALPITUDE AD, there's going to be a lot of value in biomarkers as context to add to the primary endpoint, which as Eric rightly points out, are the cognitive endpoints. But there's a richness to the data that these biomarkers are bringing, and so for us we think it's going be an important part of the story. And in addition to the markers that we're currently measuring, we're also careful to do plasma sampling to allow us to do additional work as the field continues to learn. Sarah MedeirosBioPharma & Biotech Equity Research Associate at Cantor Fitzgerald00:15:35Great. Thank you. Operator00:15:38Thank you. Our next question comes from Tom Schrader with BTIG. You may proceed. Thomas ShraderMD & Healthcare Analyst at BTIG00:15:47Good morning. Thanks for taking the questions fairly related to the last questioner. But as it seems like the commercial antibodies are getting some traction and two companies are working very hard. Are you finding that that poses any risk to your trial? Is your dropout rate about where you thought it would be given you had a placebo given you have a placebo arm and then I have a mechanistic follow-up. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:16:13Yeah, good question. Go ahead Eric. Sure. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:16:17Well, okay. Yeah, so no, it's a good it's a great question and it's something that we've thought about quite a bit is because there now are two FDA approved drugs, at least in The United States, could that be a risk to our study? And so far that's just not been the case, and as you know the launch of both of those drugs with lucanumab being a little soon having a little more history to it now has been relatively slow, a lot of that we think is due to just infrastructure not being present and it'll continue to be built. But the bottom line is for our ALDITUDE study, you know again as Dan mentioned previously, the enrollment rate was much higher than we had actually projected. So we enrolled you know five forty two people in ten months, which is pretty substantial. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:17:16But then in terms of discontinuation rates, know this is an ongoing blinded trial and we finished enrollment you know a relatively short period of time ago, but so far the discontinuation rate looks looks quite good. So we're not seeing problems with these marketed drugs. One of the things to keep in mind is that we do have an open label extension at the end of the study, so people who get randomized into altitude, so it's a three arm study, one arm is placebo, so chances are two out of three that you're not on placebo, and then when you get to the open label extension a hundred percent of people will be on drug. So we think that's one of the study design aspects that's really made this an attractive study for people and so far the studies progressing, you know, very nicely. Thomas ShraderMD & Healthcare Analyst at BTIG00:18:14Okay, and then for PLOSO Tau217, and you guys are all over this marker, is this the best guess for the for a useful treatment biomarker? Or is that not likely to be the case? And do you have a sense of where we sit today? What's likely to be the best treatment biomarker? Do you think your synaptic markers that are kind of novel have a better chance? Thomas ShraderMD & Healthcare Analyst at BTIG00:18:39But where do we stand on a treatment biomarker? We understand staging biomarkers are quite advanced. Yeah, Tom, this is Jim. Happy to take that one. As I was saying, we do definitely think that these plasma based biomarkers are going to be continuing to evolve. Thomas ShraderMD & Healthcare Analyst at BTIG00:18:57And I think, as you just said, staging is one clear use, and I think that's coming along. I think markers of activity or efficacy, I think everyone is asking that question. I think at this point, we don't yet know. Certainly, pTau217 is going to be critical in whatever plays out. I think my guess and our guess is that we're likely to see a series of markers that are used to both understand where patients are in their Alzheimer's journey, but also to be used to assess ongoing cognitive I don't think we're likely to see a single marker giving a clear progressive marker of cognitive activity, you're likely to see multiple markers giving you a sense as patients continue. Thomas ShraderMD & Healthcare Analyst at BTIG00:19:52And I think beyond that we'll just have to wait and see. But that would be my guess is that we'll see a number of different markers correlating with the progression of disease and that's part of what's happening right now is there are a lot of studies ongoing trying to work out which markers at which time are correlating with function. So stay tuned. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:20:13Yeah, the interesting thing about that question is that these biomarkers can be used either for diagnostic purposes or to assess drug effects. Lot times the same biomarker can be used to do both, And so it gets a little confusing in terms of what's the purpose of your biomarker, but but you can use them either way, either as a diagnostic or as evidence of drug effect. Thomas ShraderMD & Healthcare Analyst at BTIG00:20:40Okay. Great. Thank you. Operator00:20:43Thank you. Our next question comes from Ting Lu with UBS. You may proceed. Trung HuynhExecutive Director - Equity Research at UBS Group00:20:50Good morning, and thank you for taking our question. I have a follow-up question on biomarker, maybe focusing on the synaptic biomarkers given there are increasing interest in the field on how oligomer targeted therapy may differentiate in promoting synaptic recoveries, which are not much evidenced in the plug targeted therapies yet. However, we've seen some recent data from Roche and they have shown trontinemab also meaningfully reduced synaptic biomarker like neuro granin. So can I ask what are your thoughts over the Roche's data? Also, maybe if you could talk about the overall, like, what about your updated thoughts on how competitive on the competitive position of supernatag versus trontaneumab? Thank you. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:21:52Thanks, Teng. I think Eric that kind of follows along the preview you gave of the INTERCEPT results, were short duration study, but meaningfully moving both some of the abeta tau but also the synaptic markers. I think even the VAP-two, one of the presynaptic markers achieving significance across each of the higher dose cohorts. So I think for a short duration study such as INTERCEPT, we're encouraged to think that LTT AD is certainly positioned to read out in potentially a more impactful and broader way. We'll just, we'll have to see. Daniel O'ConnellCEO, President & Director at Acumen Pharmaceuticals00:22:34I think, you know, we're now positioned to read out the study next year. So excited about that prospect. Eric SiemersChief Medical Officer at Acumen Pharmaceuticals00:22:44Yeah, right. I mean, INTERCEPT may not have been the very first study to measure these synaptic biomarkers, but it was certainly one of the first. And as you point out with fructanomab now, for example, it's something that the field is looking at broadly. So we're pleased that we were one of the first studies to show effects on synaptic biomarkers, and obviously we'll look at those in our ALTITUDE study in addition. Trung HuynhExecutive Director - Equity Research at UBS Group00:23:18Thank you. Those are really helpful. Operator00:23:24Thank you. I would now like to turn the call back over to Alex Braun for any closing remarks. Alex BraunVP & Head of Investor Relations at Acumen Pharmaceuticals00:23:29Great. Thanks, Josh, and thanks, everyone, for taking the time and for joining us today. We are available at the company anytime for additional questions. And with that, I hope you all have a great day.
