Thank you, Daniel. Good afternoon and thank you for joining us on today's call to discuss ACADIA’S second quarter 2024 earnings. Joining me on the call today from ACADIA are Steve Davis, our Chief Executive Officer, who will provide some opening remarks, followed by Brendan Teehan, our Chief Operating Officer and Head of Commercial, who will discuss our strong commercial franchises, DAYBUE and NUPLAZID. Also joining us is Elizabeth Thompson, PhD, Executive Vice President, Head Of Research and Development, will provide an update on our pipeline programs and Mark Schneier, our Chief Financial Officer, who will review the financial highlights. Steve will then provide some closing thoughts before we open up the call to your questions. In addition, Parag Meswani, Senior Vice President, Trofinetide - Rare Disease Franchise, as well as Kimberly Manard, Senior Vice President, Global Strategic Planning and Execution will be available for the Q&A session. We are using supplemental slides which are available on our website's events and presentations section.

Thank you Al. Good afternoon everyone, and thank you for joining us. Please turn to slide five. The foundation of ACADIA'S business is built on our two commercial products, NUPLAZID for the treatment of hallucinations and dilutions associated with Parkinson's disease and DAYBUE for the treatment of Rett syndrome. Together, these commercial franchises delivered $242 million in revenues for the second quarter. In addition to these successful commercial products, we have a deep and growing pipeline headlined by our Phase 3 Prader-Willi syndrome program and our Phase 2-Phase 3 program in Alzheimer's disease psychosis. Our two profitable franchises drove 46% year-over-year revenue growth and provided ACADIA with a strong financial foundation. We are a cash flow positive company and now have over $500 million in cash with no debt. This gives us a great deal of confidence in our ability to fund future growth by advancing our current pipeline programs as well as investing in future business development opportunities. Please turn to slide six. I'll now discuss some highlights from each of our commercial products that Brendan will expand upon further in his section. I'll begin with DAYBUE. In the second quarter DAYBUE net product sales were $84.6 million, up 11% sequentially during the quarter, we returned to growing active patients on therapy. Today we are at 900, which is back to where we ended 2023 following the surge of new patients we experienced soon after DAYBUE's launch and is 66 patients above our low point late in the first quarter. Consistent with our expectations, numerical discontinuations dropped significantly in the quarter, with the rate of weekly discontinuations decreasing 46% in the second quarter versus the first quarter. New patient starts rebounded in the quarter, but with the rate of weekly starts increasing 12%, this rate of growth was slower…

Brendan Teehan

Analyst

Thank you, Steve. Today I'll be focusing my comments on the current state of business in our NUPLAZID and DAYBUE franchises. Starting with DAYBUE, my comments will address three key areas. First, results to date in 2024. New data we are messaging based on the real world experiences from caregivers and healthcare providers and core elements of the business that drive the long term value and revenues. Please turn to slide nine. Let's start with how the business has progressed thus far in 2024. The second quarter marked a return to growth in total active patients on DAYBUE. As the first quarter saw a slowdown in new starts. That dynamic, coupled with the first quarter increase in numerical discontinuations associated with the large surge in new patient starts soon after launch, resulted in a decline in total active patients during the first quarter. Our second quarter recovery in total active patients was driven by a sequential increase in demand and a decrease in numerical discontinuations. First, we generated an increase in new patient starts on DAYBUE, with weekly new starts coming in 12% higher than in the first quarter. At the same time, we experienced a significantly lower rate of weekly discontinuations, decreasing 46% in the second quarter versus the first quarter. While we made important progress on both fronts in the second quarter, our rate of increasing active patients on therapy was slower than anticipated. This is a function of numerical discontinuations decreasing in line with our expectations. But our rate of new patient starts while growing total patients on therapy has been slower than projected. As we expand our penetration in high volume institutions and community practices, there are obviously substantially more physicians we're engaging, each of whom we need to educate, on the clinical benefits of DAYBUE…

Thanks Brandon. I'd like to start out by saying that it's a pleasure to be with you all today. I'm pleased to be joining the Acadia team. I came here based on my enthusiasm for what our marketed medicines are bringing to patients, for the potential of our pipeline and the opportunity to continue to feed and grow that pipeline. I look forward to our conversation today and going forward now turning to today's content, we continue to make progress on enrollment in our late stage clinical programs. First, let's turn to Slide 16, which gives an overview of our ACP-101 program in Prader-Willi syndrome. Let me start with some background on the disease. Prader-Willi is a rare genetic neurobehavioral disorder that affects approximately eight to 10,000 patients in the United States. Its defining characteristic is hyperphagia, which is an unrelenting hunger, a constant craving for food that never ends because patients living with Prader-Willi never feel full. This manifests very early in life and can lead to obesity and myriad complications like type two diabetes or heart disease, as well as behavioral changes like aggression and anxiety. And unfortunately, life expectancy is currently only around 30 years old, largely due to cardiovascular disease. Please turn to slide 17 as a reminder, we're currently running a Phase 3 study called Compass PWF. This study is global, multicenter, randomized, double blind and placebo controlled. Building on the prior Phase 3 experience. This trial focuses on the 3.2 milligram dose that was previously shown to reduce hyperphagia related behaviors. We also utilize the same primary endpoint as was used previously, the hyperphagia questionnaire for clinical trials. We anticipate giving more specific guidance on timing as we get further into enrollment, but thus far it is proceeding well. We've been truly pleased with…

Thank you, Liz. Let's review our quarterly financial performance on Slide 22. In the second quarter, we recorded $242 million in total net sales, up 46% from the second quarter of last year. DAYBUE net product sales were $84.6 million in the second quarter, up from $23.2 million in the second quarter of last year. Sequentially DAYBUE net sales were up 11% from the first quarter, comprised of 7% follow growth and a 4% increase in net price. NUPLAZID net product sales were $157.4 million in the second quarter, up 11% versus the prior year's second quarter. Gross to net for NUPLAZID was 23.8%. In Q2, our NUPLAZID franchise achieved 4% demand bottle growth and 6% sell in bottle growth. When comparing Q 220 24 to Q 220 23 in this year's quarter, our sell in modestly outpaced demand, while demand modestly outpaced sell in last year's quarter. On a year to date basis for 2024, sell in has equal demand. R&D expenses increased to $76.2 million in the second quarter of 2024 from $58.8 million in the second quarter of 2023. The increase in research and development expense was mainly due to increased costs for ACP-101, ACP-204, and early stage programs, partially offset by a reduction in costs associated with our pimavansarin negative symptoms of schizophrenia program. SG&A expenses increased to $117.1 million in the second quarter of 2024 from $96 million in Q 220 23. The increase was primarily driven by upfront costs related to a new consumer activation program to support our new closet franchise. Increased marketing costs increased us to support JVU, and investments to support the potential commercialization of trophy outside the US. We ended the quarter with a cash balance of $500.9 million, which increased $30.4 million versus the first quarter. Please turn to…

Thanks much Mark. Please turn to slide 24. We have a strong foundation for our business today and are excited to build on our successes and drive future growth. We're focused on continuing to execute on the significant opportunity that remains in front of us for both DAYBUE and NUPLAZID. We look forward to further enrolling our two late stage programs, including our Phase 3 program for Prader-Willie syndrome and our Phase 2, Phase 3 program in Alzheimer's disease psychosis. We're pleased to have these exciting pipeline assets while at the same time being in a position to generate sustainable and increasing cash flow from operations to fund future growth. With that, I'll now turn it over to the operator for Q&A. Operator?

[Operator instructions]. And our first question comes from Ritu Baral with TD Cowen. Your line is open.

Ritu Baral

Analyst

Good afternoon, everyone. Thanks for taking the question. I guess I wanted to ask about the difference that you guys are seeing in the ongoing discontinuation rate and the new start rate between the community and the COE. I believe you said that two thirds of the new prescriptions were coming from the COE, like high volume in the community. But, how are those centers and doctors managing discontinuations versus the COEs? And then I was wondering, second part of this 1Question, how the dose titration discussion that was featured significantly at IRSS factored into that as well. Thanks.

Steve Davis

Analyst

Thanks much for the question, Ritu. Brendan, you want to take that?

Brendan Teehan

Analyst

Sure. Thanks, Ritu. So, first, just in terms of discontinuation rates between COEs and non COEs, we see it's reasonably steady between the both, meaning to say that there's more consistency that we see in our persistency curves, whether you're in a COE or a high volume institution. From a new patient start perspective, our audience will recall that we started in COE's and had excellent uptake. Obviously, these were the practices that were involved in our clinical trials, the vast majority of them. So our penetration of COEs was and is significantly higher than it is outside of those COE. So it's logical that as we continue to talk about the DAYBUE message and expand our breadth, the majority of our prescriptions are going to, over time, begin to come from non COEs and from the community. As a reminder, about a quarter of all Rett patients will be found in centers of excellence, of which there are now 21. So it gives you a sense for just patient processing ability from that segment. And then the other 75% are going to be found in these high volume and community practices. So we continue to increase our penetration there. Two thirds of our new starts come from there. And we still have a steady flow -- flow of about a third of our prescriptions coming from COEs. I think you also made a reference to IRSF for dose titration. I'll try to touch on that, if I don't answer your question. Please ask it differently. But we did speak at IRSF about dose titration and the ability of physicians, if they deem it appropriate, to start at a slower dose, a lower dose and titrate up. We are definitely seeing that. And we're seeing that both in COEs and outside of COE's. We also have been encouraging families to stay in close contact with their physicians to make sure that if there are needs to make any adjustments to their GI plan, they do that in the first two to four weeks. All of that is intended to help increase the ability of patients and families to stay on therapy through those first early couple of weeks on treatment with DAYBUE and get out to the benefits that we expect they'll see with longer term treatment.

Thank you. And our next question comes from Charles Duncan with Cantor. Your line is open.

Charles Duncan

Analyst · Cantor. Your line is open.

Hi. Yes, thanks for taking the question. Unfortunately, it's a two parter and that is related to the bookends in terms of DAYBUE guidance. Now that we're in the third quarter, I guess I'm wondering what gives you confidence to hit one end versus the other? What has to happen? And then just a clarification from Liz. I wasn't sure I understood. Are you going to read out the Phase 2 from the ACP-204 study and then the Phase 3? Could you go back and repeat your comments there? Thanks.

Steve Davis

Analyst · Cantor. Your line is open.

Yes. Thanks much for the two part question. Charles. Mark, you want to answer the first part?

Mark Schneyer

Analyst · Cantor. Your line is open.

Yes, sure. Thanks for the question. I guess in terms of day view guidance, where we're tracking today with kind of all the key metrics, I would say we're tracking towards the lower half of our revised guidance range. With all the initiatives that we have in place and the new information and data that we're going to share with HCPs and caregivers about benefits and GI management plans, we think all of that can take us to increasing our metrics and getting towards the high end of the range and the low end of the range would need to see our metrics turn a little backwards from what we're achieving today.

Steve Davis

Analyst · Cantor. Your line is open.

Okay, Liz?

Elizabeth Thompson

Analyst · Cantor. Your line is open.

Absolutely. So for clarification there, So how this is going to work is that sites can enroll in the Phase 2 and then sites that are not in the EU, once they're done enrolling in the Phase 2, move over and start enrolling in the Phase 3. So what that means, practically speaking, is that Phase 2 data are going to come out while the Phase 3 is still enrolling. So we think that's actually going to be helpful thing to then continue to spur enrollment thereafter. And it will help the EU to come on quickly because Phase 2 data are always motivational for physicians and for patients. So hopefully that clarifies it.

Thank you. Our next question comes from Gregory Renza with RBC Capital Markets. Your line is open.

Anish Nikhanj

Analyst · RBC Capital Markets. Your line is open.

Hi, guys, it's Anish on for Greg. Thanks for the updates from this quarter and for taking our question just on DAYBUE, how are you thinking about the potential impact of the summer months with respect to drug holidays? Time to start and even restarts. What are you seeing so far into the summer months? And as a supplement, could you quantify for us what percentage of patients that have taken DAYBUE, that have stopped, have not restarted? Thanks so much.

Steve Davis

Analyst · RBC Capital Markets. Your line is open.

Thanks so much for the question. Brendan, you want to take these?

Brendan Teehan

Analyst · RBC Capital Markets. Your line is open.

Sure. Thanks. So I would say that the summer looks like the summer in terms of what we see for just patient cycling July, there are patients that are taking holidays. There are also HCPs taking holidays, but COEs are operating at the same cadence. And we would expect that we will, as families come back from vacations and get into the regular preparation for the upcoming school year that we would expect to see our new patient starts continue to progress as we get into August and September. The second question was around discontinuations. There are really two different types that we've described. One is a discontinuation where a family has told us, and as we have really exquisite relationships with our patients and families. We have our fam team that's out in the field with them, as well as our clinical nurse coordinators that speak with them on a regular basis. So we know a patient is discontinued. But there are also those who may just be taking a pause, maybe having a medical procedure, and may just have a lapse in treatment. What we've seen over time is if you have, if you've gone out past 60 days, there's still about 20% of those patients that will come back to refill, if that gives you some sense for it. In terms of actual discontinued patients, fewer patients that discontinued have, at least to date returned to DAYBUE treatment.

Thank you. Our next question comes from Joel Beatty with Baird. Your line is open.

Joel Beatty

Analyst · Baird. Your line is open.

All right, congrats on the progress, and thanks for the detailed update. For the 70% of diagnosed patients who have not initiated on DAYBUE, are you able to break that group down into any market segments that might be helpful for thinking about that opportunity, such as perhaps, what percent have awareness of DAYBUE? Or what percent have discussed it with a physician? And then as a second part, you mentioned a survey that mentioned that over the next 24 months, healthcare professionals expect to increase the prescriptions to DAYBUE to more than 70% for their patients. Anything about what percent of that surveyed population they were currently at that point in time of the survey? Thanks.

Steve Davis

Analyst · Baird. Your line is open.

Yes. Thanks much for the question, Brendan?

Brendan Teehan

Analyst · Baird. Your line is open.

Thanks. I may ask you to repeat the second question. You trailed off at the end. I wasn't sure what that was, but I can answer the first one for sure. So in terms of the 70% of the population that remains first, I would remind everyone that DAYBUE has a very broad label. It is for ages two and up. We see both male and female patients being treated. And thus far, the patient population is very much reflective of the prevalent population. So we see a wide range of ages and disease severities treated. In terms of the remaining 70%, unsurprisingly, the highest penetration that's expected is in the two to 20 year old range. It's slightly lower in the 21 plus percent range, but it's still substantially higher than what physicians have been treating to date. And then for the second question, I didn't hear precisely how it was stated.

Joel Beatty

Analyst · Baird. Your line is open.

If the docs expect to be treating 70% of their patients in the future, what percent of their patients are they currently treating today according to the survey?

Brendan Teehan

Analyst · Baird. Your line is open.

Sorry. Good. Thanks for the repetition. So we know that we have prescriptions. We've started 30% of patients. We have prescriptions for more than that. And the physicians that responded felt that their patient population, they had treated about 40%. So when I say 70% in aggregate, that's stating that they would have increase from their 40% to a total of their total addressable population of approximately 70%, which varies by age category.

Thank you. Our next question comes from Marc Goodman with Leerink. Your line is open.

Marc Goodman

Analyst · Leerink. Your line is open.

Yes, we've talked a lot about DAYBUE, but can you talk about new closet a little bit? Just the rest of the year, the puts and pulls on making the high-end and low end the numbers?

Steve Davis

Analyst · Leerink. Your line is open.

Thanks. Yes, thanks much for the question. Mark Schneyer, you want to take that?

Mark Schneyer

Analyst · Leerink. Your line is open.

Yes. Thanks, Mark. On NUPLAZID. Yes, sir. We're certainly pleased with our performance to date and have increased our range. As we talked about on the prepared remarks for NUPLAZID and the metrics where we are today, we're tracking around the midpoint of the guidance. So kind of high and low from there, outperformance, we'll, we'll have new patient starts kind of beyond where we're tracking towards today and potential, early positive benefits beyond our timing expectations for the DTC campaign. You know, lower end would just be us, falling a little behind our performance of where. Where we are today. And then, of course, with the brand in closet, small fluctuations of gross to nets or in channel inventory can impact, where our final results will be for the year.

Thank you. Our next question comes from Jeff Hung with Morgan Stanley. Your line is open.

Jeff Hung

Analyst · Morgan Stanley. Your line is open.

Thanks for taking my question for ACP-101. And Prader-Willi, can you just talk about your confidence in your approach versus what, excuse me, what competitors are doing? What is your current thinking about potentially expanding development into other indications with hyperphagia or obesity? Thanks.

Steve Davis

Analyst · Morgan Stanley. Your line is open.

Yes. Thanks much for the question. I'm going to ask Kimberly Manhard to take that.

Kimberly Manhard

Analyst · Morgan Stanley. Your line is open.

Yes.So, with respect to Prader-Willi, you're probably aware of Selena's compound, DCCR, which is Dizoxide Choline control release. Diazoxide, actually originally approved for hypoglycemia. So it's been out in the market for some time. But this is a different form, colonized oxycholine. And they have indicated back in late June that they filed their NDA, and so they had a randomized controlled trial that was not positive for the overall data set. But when they looked at it in patients and data up through the start of COVID they were able to see statistically significant difference between the placebo and active. And then they conducted an open label extension, and from that open label extension, gained agreement to do a randomized withdrawal period of the open label extension and saw positive benefits. But we think that there are a lot of opportunities for treatment of hyperphagia and Prader-Willi syndrome. It's a very devastating disease, and new treatments are needed. If the product is approved, then we've done an analysis to show that they should be able to be given together, since there are very different mechanisms of action and also there's no PK interaction or no overlapping toxicities. Their main toxicities were hypertrichosis and pulmonary edema and hyperglycemia. So we don't see those in our trials.

Steve Davis

Analyst · Morgan Stanley. Your line is open.

And, Jeff, maybe just to annotate that a little bit, I think that the confidence in our making an investment here and in running a Phase 3 study really comes from the data. It comes from the Phase 2 data, where we see a nominally significant reduction in hyperphagia associated with Barter Lilly syndrome At the dose that we're testing. It's the same primary endpoint in the Phase 3 studies, the Phase 2. And so there are lots of things that go into these assessments, but the principal data that we're resting on is that phase II data.

Keith Tapper

Analyst · BMO Capital Markets. Your line is open.

Hi, team. Congrats on the quarter, and thanks for taking my questions. Congratulations to Liz on the transition to Acadia. First question on Dave, would it be helpful to understand the impact of the community engagement and, how that's underway to address discontinuations? Just wondering, on the effort or the impact of GI management efforts on patient dynamics, could you provide color on when the efforts began to reach the community and when the impact should feel fully realized? And is there an effort to drive restart, maybe through patient claims, surveillance, or revisiting providers? Thanks.

Steve Davis

Analyst · BMO Capital Markets. Your line is open.

Yes, thanks much for the question. I'm going to ask Parag Meswani to address those questions. Parag?

Parag Meswani

Analyst · BMO Capital Markets. Your line is open.

Yes, thanks for the question. So, as a reminder, in our last call, we talked a lot about the consistent application of GI management and GI mitigation strategy. That's an ongoing effort. We do that with physicians on a regular basis, and we're doing that with caregivers on a regular basis as well. So it's ensuring consistent implementation of simple things like stopping constipation medications, adding fiber to your diet, hydration, and use of loperamide. Dose modification is a new part of the algorithm that's now being utilized more and more often as well. We're starting to see the impact of that. You saw that in the second quarter. We've begun to implement a more consistent message to providers and caregivers on that. We've started to see some of the benefits of that, just in terms of the total active patients on therapy and the decline in numerical discontinuation that we saw in the past quarter. And we'll continue to reinforce that for the remainder of this year. On restarts, we're beginning to see some patients begin to come back onto therapy, but our focus has been on ensuring a very positive treatment initiation. It's important for those patients that have been on therapy for the long term.

Thank you. Our next question comes from David Hoang with Citigroup. Your line is open.

David Hoang

Analyst · Citigroup. Your line is open.

Hi there. Thanks for taking my questions. So I wanted to ask about patients on DaVU long-term. Do you have any data points or maybe kind of the earliest patients that initiated therapy have any reached a year or more? And do we have any visibility on, I guess, twelve month persistency rate compared to nine months? And then just one follow up would be on ACP-204 if I heard correctly, it sounded like EMA did not agree to a seamless Phase 2 three protocol. And so I'm just curious as to kind of why that might be. What was the pushback and how might that impact the regulatory path in Europe? Thank you.

Steve Davis

Analyst · Citigroup. Your line is open.

Yes, thanks much, David. Brendan, you want to take the first question? And then Liz, you want to take the second one?

Brendan Teehan

Analyst · Citigroup. Your line is open.

For sure. Thanks, David, for the question. And as I said in my prepared remarks, we actually have a number of patients that are out past two or three years that are on day view. And actually in some of our programming, we have caregivers of those loved ones that speak about the benefits they're seeing at six months, at a year and two years, often providing really the marker for other families on what they might hope to see with longer term treatment. You also asked about persistency curve. So the Lilac one study, the placebo rollovers are the ones that we're using to look at our performance in the real world, as opposed to that study where we tracked ten or more percentage points above that, out to nine months. And at twelve months, we don't have a comparator to give you, but are still seeing excellent persistency rates, well above 50%, that give us that confidence in the longer term persistency we're expecting to see in the real world with the support we're able to give.

Steve Davis

Analyst · Citigroup. Your line is open.

And just one additional point there. Of all the patients that started DAYBUE in our Phase 3 program, 40% of them are still on DAYBUE today. So again, they've been on therapy for three plus years. And of all of those patients that rolled over on the commercial drug, they've all stayed on therapy during the 15 months that we've been on the market, with exception of one patient that discontinued.

Elizabeth Thompson

Analyst · Citigroup. Your line is open.

And for the 204 point, just to clarify. So how we were doing this is running it under a master protocol. And it was really just a master protocol concept that the EU had an issue with at this point. So we fully anticipate running Phase 2 and then running a separate, rolling them into Phase 3 at a later time. So Europe will participate in the Phase 3. We anticipate that this is going to be acceptable for regulatory purposes, but it's really just that they can't go straight through with the seamless enrollment under a master protocol right now.

Thank you. Our next question comes from Paul Mannis with Stifel. Your line is open.

Unidentified Analyst

Analyst · Stifel. Your line is open.

Hey, this is James. I'm for Paul. Thanks for taking our question. Maybe one on NUPLAZID. And you mentioned the DTC and you don't expect the effect to kind of really take it, to take effect until 2025 and 2026, I guess. What are your expectations in terms of what growth can look like, what your ROI on DTC could look like for NUPLAZID? And then can you just remind us on how Grossnet's going to evolve for NUPLAZID over time? I missed it a little bit, so I just want to make sure. Thanks.

Steve Davis

Analyst · Stifel. Your line is open.

Yes, I'll take the first question mark. I'll ask you to answer the second. We've run DTC campaigns previously in the NUPLAZID franchise. It's an important part of the communications. This patient population, as we mentioned in our remarks, turns over pretty quickly. And so there's a kind of a continual feed of new patients that have not heard messaging before. And we, based upon the previous DTC campaigns we've done, we've seen, we've had very positive ROIs and we've seen a meaningful impact on being able to grow this franchise. We're now eight years in. We paused DTC during the pandemic and the few years since because the market was pretty turbulent and it just wasn't an ideal environment for making these investments. We indicated at the time that if market conditions change and we see an opportunity to make these investments, we will. The opportunity set we have today, I think, is really as well as, as an attractive, a setup as it could be. As Brendan described in his remarks, the awareness of hallucinations and delusions is down dramatically. That's important because when patients are diagnosed with Parkinson's disease, many times their physicians don't talk about hallucinations and delusions because they don't come up until years later and they only impact about half the population. So when they happen, these patients just don't make connect the dots. They just don't associate them with Parkinson's. So many times they go untreated for very long period of time. And so it's really important to get this messaging out there. I think we have a very, very fertile environment to make this investment, and we're very excited about making it.

Mark Schneyer

Analyst · Stifel. Your line is open.

And I can jump into, to address the question on gross to net. So, for next year, starting 2025, we expect the Medicare part d redesigned to take place. And as part of that, we will qualify for the specified small manufacturer phase in, as I mentioned in the prepared remarks. So as we look from gross to net for this, from this year to next year for NUPLAZID, we expect our gross to net, go down by about 300 basis points. As that small manufacturer phase in starts. And then from there, gross net will likely gradually increase as that small manufacturer phase in unwinds over the coming years.

Yes. So as we said in the prepared remarks, our volume and price split sequentially for DAYBUE was 7% bottle growth. So essentially volume and patient growth and 4% net benefit from price as we took a price increase midway through the second quarter.

And for the second question, around the 900 patients, just a couple of things. There's, as a reminder, it was towards the end of the first quarter that we hit sort of our low point for patients, active patients on treatment throughout that time period. Moving forward, we've seen nice incremental month over month growth in active patients. So, 900 wasn't a sudden overnight thing. This was a fairly steady progression. Of those 66 patients added over a 90 plus day period. And I might just add to that, that if you start looking at things on a daily or weekly basis, which we do every day, of course, things move around a little bit. Last week was one of the best weeks we've had in a couple of quarters. So we're hesitant to try to break things down in two shorter period. But as Brendan mentioned, the trend that we've seen has been a consistent trend throughout the quarter.

Hi. Good afternoon, Stephen team. So specifically, where are you most focused with respect to your commercial strategy for the second half year, particularly accelerate ads and for DAYBUE. And have you thought about altering or changing your sales infrastructure to best target key providers or new providers? And can you also just remind us what is your current prescriber base number and where that is sitting versus your overall target? Thanks.

Steve Davis

Analyst · JPMorgan. Your line is up.

Thanks much. Keep us honest here. Make sure we answer. I think it was a three part question I'm going to ask.

Parag Meswani

Analyst · JPMorgan. Your line is up.

Yes. So I'll start with the first question, which I think was where are we going to source growth from here, from an ACP perspective, one thing I'll say the outset is there's still plenty of opportunities at the centers of excellence. They are still a core constituent in driving prescriptions and patient ads. But we have been pivoting our business and our priorities outside of the centers of excellence for all the reasons that we've talked about before. Three out of four patients are being seen outside of COEs. They are getting more and more comfortable with this new tool in their toolkit. And at this stage, we're seeing a very even distribution of where our prescriptions are coming from. About a third from COE, about a third from that middle bucket of high volume institutions, and a third from the community. And we're going to continue to fish where the majority of patients are being seen. And so our priority has been, and continue to be for the remainder of Q3 and into Q4, growing our business and getting our fair share of business from the rep population that is being treated outside of the rep centers of excellence. And we expect to see continued breadth of prescribing in those account settings, but also depth of prescribing. We have well over 700 unique prescribers at this point. Some of just prescribed AB to a single patient. And our goal is to continue to get more physicians to prescribe and for those that have more than a patient, and prescribe it to more of the patients that they are currently treating.

Thank you. Did we catch all aspects of your question? I think Brendan maybe has.

Brendan Teehan

Analyst · JPMorgan. Your line is up.

I can speak. Yes, I think, Tess, you spoke a little bit to structure and frog. If I miss anything, feel free to add to it. But yes, I think 16 months in, we've seen a couple of great opportunities that have emerged. We put a team out there called the pace team. That's the patient and community education team. This is for families that have expressed a lot of interest in DAYBUE and more information, but have not yet signed up for a prescription. Unsurprisingly, as people learn more and more, they have a lot of questions, some of which clinicians can clearly answer, but others, they just want to know about the access and reimbursement process. They want to know what's the support they're going to be able to get from Acadia along the journey, which gives us a chance to talk about our FAM team and others. So we've had already successes of families meeting with our pace team members and then deciding to get started on a prescription. We have them all placed regionally so that they can be face to face with families, either individually or at community gatherings. And as so we're heading into Rett awareness month or really what I would call more like Rett awareness quarter because it happens between September and November really where we'll have lots of opportunities to engage those families. Then we also have TLL's or thought leader liaisons that are engaging with thought leaders in Rett, but also thought leaders that have a lot of experience with DAYBUE to help just better describe the treatment journey, the do's and don'ts, and how to be successful in starting patients on therapy. So a couple of enhancements to our promotional field footprint.

Parag Meswani

Analyst · JPMorgan. Your line is up.

Yes, the only thing I'll add Tess to what Brendan said is we currently have with our field sales footprint, 100% coverage. So with the 5000 plus patients that are out there, we have 100% coverage of the treating physician. For all of those with the field footprint that we have, we continue to fine tune that model. And Brendan mentioned a couple of fine tune adjustments to that, which is the addition of new roles that give us great opportunities to engage with the prescriber base on the keeping and leader side, but also to have a new resource that can engage directly with caregivers and help them better understand JB's product profile and whether it's right for the long term.
