Thank you, Gayathri, and good afternoon to everyone joining today's call. Turning to slide 3, we are pleased to provide an update on our corporate progress and share our second quarter results. We continue to execute on our mission to develop innovative therapies for patients with endocrine diseases and endocrine-related tumors. As we approach the pivotal moment of our pending approval of our first NDA, I am pleased to report strong execution across all aspects of our business. I want to begin by reaffirming that the Paltucidine NDA review remains on track. We continue to work closely with the FDA towards an anticipated approval in September. We are grateful for the FDA's commitment to this important work and their collaborative approach throughout the process. Our regulatory team has maintained excellent momentum and remain confident in our timeline and preparations for what will be a transformational launch for We've assembled an outstanding launch team of experienced professionals, both in our headquarters and in the field, who bring deep expertise in endocrinology and rare disease commercialization. The caliber of talent we've attracted speaks to the excitement around CalSanify and its potential impact on patient care. Recently, we hosted a group of more than 40 people living with acromegaly at our headquarters in San Diego as part of our ongoing engagement with the patient community. We have worked with the Acromegaly Advocacy Group since before palthusatine entered the We continue to seek their insights to shape our commercial strategy. At this most recent patient event, I heard directly about their experiences with their disease and their interactions with the healthcare systems around the country. After talking with them personally, I am more confident than ever that Palsonify's profile addresses a critical unmet need that will make a very positive impact on all these patients' daily lives. Deeper in the pipeline, we continue to make progress towards initiating four additional pivotal programs. Trials of paltucetine for the treatment of carcinoid syndrome and etumelanat for the treatment of adult and pediatric congenital adrenal hyperplasia are ramping up now. We remain highly encouraged by the potential of etumelanat's novel mechanism of action in ACTH dependent Cushing syndrome and following extensive conversations with multiple regulatory authorities anticipate initiation of a phase 2-3 study in the first half of 2026. The enthusiasm for our earlier pipeline continues to build. The phase 1-2 study of CRN 9682 and SST2 expressing solid tumors is ramping up and our work towards IND submissions across multiple additional discovery stage programs continue as you may have seen we've been extremely active at several key endocrinology conferences over the last few months including endo 2025 last month in san francisco we delivered six poster presentations and two oral presentations covering palsonify and acromegaly atumelanet and cah and our thyroid stimulating hormone or tsh receptor antagonist program we also hosted product theaters and innovation sessions to highlight our pipelines differentiation and met with key opinion leaders across the different indications we are pursuing among the presentations at endo was an update of CRN 12755 our TSH receptor antagonist candidate for the treatment of Graves disease we believe this novel mechanism of action has the potential to be a single oral therapy that addresses the core driver of Graves disease in order to treat both Graves hyperthyroidism and treat or prevent thyroid eye disease. Turning back to the launch of Palsonify, I'm energized by the team we've built, the progress we've made, the strength of our financial position, and the opportunity to really transform the lives of people with sacromegaly. With that, let me turn the call over to Isabel to tell you more.

Thank you, Scott. Turning to slide four, we're incredibly excited for the anticipated launch of Palsonify, our recently-debuted brand name for Palsonify. This represents a combination of years of dedicated research and development to bring a new standard of care to patients with acromegaly. We have made meaningful progress in our interactions with healthcare professionals, patients, and payers as we approach this milestone and complete our transition into a commercial stage conference. Moving on to slide five, as Scott mentioned, craniatives had a significant presence at several prestigious medical meetings over the last few months with global key opinion leaders as well as with community endocrinology. Our presentations at pro sitters at Endo were a standing room only, and healthcare professionals were excited to engage with our team to learn more about Palsomify. They were impressed with the new data from the open-label Pathfinder 1 extension, which showed the Paltusa team maintained control of both IJ1 levels and symptoms through 96 weeks. Healthcare professionals were encouraged by this durability since many patients discontinued acromegaly treatment within a few years. They were also excited by the post-hoc analysis that demonstrated that treatment with palthusatine improved symptom stability over three, six, and nine-month time periods relative to baseline treatments with injectable SRFs. This data could present a compelling value proposition to patients, improved both symptom control and ease of use in addition healthcare professionals were reassured by the stability of reduction of tumor volumes in inpatients who had mri data throughout the ole period for both pathfinder 1 and pathfinder 2. we believe that this ole data demonstrating a stable or decreasing tumor volume over a long period will allow healthcare professionals to feel confident that Pantucetine offers tumor control as well as symptom control and disease control. Turning to slide six, with that in mind, we have built out our commercial team and are in the process of onboarding our sales force ahead of launch. We will have approximately 30 sales representatives in the field supported by additional healthcare professional-facing roles, ensuring comprehensive coverage and support for our target prescriber base. We have been impressed by both the quantity and quality of candidates who have applied for our field roles, and we are confident they represent the top talent in the industry with extensive experience in rare endocrinology and a high degree of motivation to bring Palsonify to patients. Now on to slide seven. Our market research suggests that healthcare professionals perceive Palsonify as the preferred therapy among newly diagnosed patients due to this rapid reduction of IJ1 levels and its accelerated titration time frame relative to monthly injectables. We believe there are 500 newly diagnosed patients per year who are candidates for pharmaceutical therapy. In addition, we believe that there are 11,000 currently diagnosed patients who have high unmet needs and are candidates for Parkinsonify. We believe many of these patients might be unhappy with the current treatment options and will consider starting or restarting therapy if an effective, safe, and convenient therapy were available. We are activating patients to demand more from their acromegaly therapy and believe many will want to switch to Palsonify over time. 90% of patients from our Pathfinder 1 study who were previously on SRL treatment opted to continue patosotene treatment in the OLE study, underscoring the unmet need for patients currently in injectable SRFs. Other patients are on oral therapies, like cavergoline, that are not indicated for acromegaly, and they might not have effective control of the disease. Patients on oral ocreotide might be managing cumbersome twice-daily fasting periods. It is clear that even oral therapies leave room for improvement on both biochemical and symptom control, as well as ease of administration. In addition, we share novel data on injectable SRL discontinuation rates during our science and innovation session at Endo. Over a five-year follow-up period, nearly 80% of patients on injectable SRLs did not persist with their newly started treatment regimen. Of those, about two-thirds discontinue treatment altogether. This data suggests that patients are dissatisfied with the current treatment notion and highlights the need for expanded treatment options. Low persistence on injectable SRLs when either discontinuing switching or adding on represents an opportunity for providers and patients to select a therapy like Palsonify that can better serve patients' needs. These findings highlight the needs for expanded treatment options. We hope that Palsonify can provide a new option for patients who want to stay effective and convenient treatment for their acromectal. Lastly, we believe that there are at least 17,000 undiagnosed patients. Over time, we believe we can help drive diagnosis and treatment for these patients. Moving to slide 8. Our commercial strategy is not just based on growing market share in the naive and switch patients. It's about growing the market itself by bringing in patients who might have discontinued therapy, those that couldn't tolerate injections, and those who are suboptimally treated. And over time, helping undiagnosed patients accelerate their treatment journey. We know that patient activation will be a key driver of potential uptake and have consequently launched our disease state education campaign and patient support hub well in advance. We're very pleased with the early results from this engagement initiative, as this multi-channel strategy will be essential. As we approach potential approval, our goal is to increase awareness, educate the community, and ultimately empower patients to advocate for the best possible care. Turning to slide 9, at this stage in our launch preparations, we have had numerous pre-approval meetings with commercial payers. We are also grateful for our ongoing engagement with CMS regarding Medicare and Medicaid coverage, particularly given all the changes occurring in the healthcare landscape. Payers groups have been receptive to personified value propositions, which includes faster disease control, lower treatment burden, symptom control, and improved patient adherence. Respect the trial authorization activity, we closely mirror the label we received for Parsonify, and we are actively working with payers to ensure appropriate access pathways. Our extensive market research and advisory boxes back have revealed a strong demand among healthcare professionals for a new treatment option. Endocrinologists are eager to use Palsonify across multiple patient populations, treatment-naive patients, those currently on therapy, and importantly, some patients who have been lost to follow-up due to the burden of carrying injectable therapies. Based on our data and the feedback from healthcare professionals, patients and payers, we are more confident than ever in the long-term potential for Palsonify to become the preferred treatment for the acromegaly community and our commercial strategy is anchored in delivering on that promise so we are deeply enthusiastic about the potential but sonify i want to offer a few reminders on the expected cadence of launch in the near term there are several factors that will affect uptake after potential approval first we anticipate formulary placement will take at least six to nine months after launch, which is consistent with other specialty pharmacistical launches. Second, acromegaly patients see their endocrinologist relatively infrequently, approximately two to four times per year. Consequently, we do not expect a bolus of patients on drugs shortly after approval, and instead expect adoption to gradually run in line with our outreach and engagement initiative. We are all hard at work preparing for U.S. launch, and we continue to progress in our international expansion in anticipation for a launch in Europe in 2026. With that, I will turn it over to Dana to provide a regulatory and clinical update.

Thanks, Isabel. Turning to slide 10, I'm pleased to provide an update on our regulatory progress across our pipeline, which continues to gain momentum on multiple fronts. Starting with Peltusatin and acromegaly, our ongoing FDA review is progressing as expected through the review milestones, reinforcing our confidence as we approach our September 25th Fidufa date. I'm particularly encouraged that the team we've been working with at FDA hasn't changed, which ensures important continuity throughout this critical review period. Our interactions with the European regulatory authorities also remain on track. Our medical affairs team continues to work in the field, educating HCPs about acromegaly and sharing the data we presented at AIDS, IPC, and NDA. These conferences are an opportunity to highlight our clinical results, as well as our health economics and outcomes research. These presentations and resulting publications, much of which are derived from our clinical studies, are part of a broader strategic plan to generate and disseminate evidence of the unmet need in acromegaly and the role palthusatine could play. Turning to palthusatine and carcinoid syndrome, we're making steady progress with our phase 3 program, currently have multiple sites up and running, and continue to expect to enroll the first patient later this year. We are also making significant progress on adamelment in CAH, which I will address in more detail shortly. We are revising our timelines for ACTH-dependent Cushing syndrome as we discuss with regulatory agencies how to best measure effective control given Adam Milne's novel mechanism of action. Moving to our earlier stage pipeline, we presented data on our TSH candidate at Endo. The data suggests it has the potential to be a once-daily oral therapy that treats Graves' disease, including both manifestations, Graves' hyperthyroidism and Graves' orbitopathy, also known as thyroid eye disease, or TED. Our mechanism of action has the potential to avoid the risks associated with ATDs and anti-IGF1 therapy, including liver injury, as well as hearing impairment and hyperglycemia. Lastly, we continue to work towards an IND submission for TSH and SFT3 this year and for PTH in 2026. Turning to slide 11, for adamelmin, we've achieved several important milestones in our CAH development program. As a reminder, we shared data on the first three cohorts of our phase two study in January with a primary endpoint of reduction in androstenedione, or A4. We added a fourth cohort earlier this year primarily to assess the effect of morning dosing of 80 milligrams of adamelanin and to study reduction of superphysiologic glucocorticoid doses in addition to a reduction in A4. Cohort 4 is now fully enrolled with 10 patients and so far it continues to support the favorable benefit risk profile we've observed in our clinical trials to date. We will of course continue to monitor these patients very closely and communicate anything necessary in a timely manner. We intend to share the full data from Cohort 4 in early 2026. We also presented data at endo from the Phase 2 study in CAH, including the full results from the first three cohorts, additional detail on observed reductions in adrenal volume, and reductions in novel biomarkers. Through these presentations, we continue to demonstrate our advancement of the understanding of the disease biology of CAH, as exemplified by our data on the under-recognized role of 11 oxygenated antigens in CAH. We continue to expect to enroll our first participant in the Phase III trial in adult CAH by the end of this year. Additionally, our open label extension study is actively enrolling, providing continued treatment access for patients. Moving to slide 12, we are also making progress on our registrational trial for animalin in pediatric CAH. When we debuted our phase three adult design last quarter, we outlined our ambition to assess normalization of both androgens and glucocorticoids, and we hope to achieve the same with our operationally seamless phase two, three design design for pediatric patients. I am pleased to share with you the pediatric design. The study will consist of three parts. Part A is the phase two, which is an open-label dose-finding eight-week study that will evaluate safety, efficacy, and reduction of A4 and PK-PD. Part B is the phase three, which will be a double-fined placebo-controlled study that will assess safety and efficacy, including the ability to taper GCs. Part C is the open-label extension study for Parts A and B, wherein patients from Part A will also have the opportunity to taper GCs. We believe our clinical trials are designed to demonstrate differentiation of adamelanin with an uncompromising endpoint and the goal developing a new standard of care for patients with CAH. Overall, I am pleased with the significant progress we have made across our early and late stage programs, and we look forward to providing future updates on each. With that, I will hand the call to Toby to provide a financial update. Toby?

Thank you, Dana. Turning to slide 13, I'm pleased to review our financial results for the second quarter of 2025 were to reflect our continued disciplined execution and strategic investment in advancing our pipeline and commercial capabilities for the second quarter we recognized one million dollars in revenue from our licensing and supply agreements with our japanese partner skk our research and development expenses for the second quarter were 80.3 million dollars compared to $76.2 million in the first quarter. This increase reflects our continued investment in pursuing multiple clinical programs, including progression of paltuzetine for carcinoid syndrome, at the MELNAP through late-stage development, and advancement of our novel non-peptide drug conjugate platform into first-in-human studies. Selling, general, and administrative expenses were $49.8 million for the second quarter compared to $35.5 million in the first quarter. This increase primarily reflects our strategic investment in building commercial capabilities, including our field sales force and our broader corporate infrastructure as we prepare for Palsanify's launch. We used $77.8 million of cash on a net basis during the quarter, reflecting continued clinical development and launch preparation activities. We ended the quarter with $1.2 billion in cash, cash equivalents, and investments. As of July 29, 2025, we had approximately 94.2 million shares of common stock outstanding. On a fully diluted basis, we had 111.9 million shares outstanding. Moving to slide 14. Looking ahead, we are lowering the high end of our guidance for net cash used in operations in 2025, and now expect to use between $340 million to $370 million, compared to our previous guidance of $340 million to $380 million. dollars. This guidance reflects greater precision on clinical timeline estimates and prudent measures we have taken on overhead growth. We expect net cash used in operations in the second half of the year to be higher than the first half of the year as our late-stage trials gather momentum and our commercialization activities accelerate into an anticipated approval. Based on our current operating plans and cash position, we maintain our guidance that our existing cash and investments will be sufficient to fund our operations into 2029. This provides us with significant runway to execute on multiple value-creating milestones, including the Palsanify US launch and the advancement of our broader pipeline. With that financial overview, I'll now turn the call back to Scott for some closing remarks.

Thank you, Toby. Now turning to slide 15. I want to emphasize the strong execution we're demonstrating across all aspects of our business. Our NDA for paltusitine remains on track with continued collaborative engagement with the FDA. I remain very confident about our launch readiness, supported by the outstanding team we've assembled, and our comprehensive of corporate readiness for the upcoming launch. We expect multiple Phase III and earlier stage readouts across various programs up and down our pipeline over the next several years. We look forward to providing updates as our pipeline continues to mature. As we move through 2025, I'm excited about the opportunity ahead of us to introduce a potential new standard of care for acromegaly patients. We are well positioned to achieve multiple value-creating milestones that will transform Chronetics into the premier endocrine-focused global pharmaceutical company. Thank you all for your continued support. And with that, I'll hand the call back to the operator to begin the Q&A. Please limit yourselves to one question, one question only, in the interest of time. Operator?

Thank you very much. We'd like to start the Q&A. If you'd like to ask a question, please sit down by pressing star followed by one on your telephone keypad to To remove yourself from the line of questioning, be staff followed by two. Our first question comes from Joe Schwartz from Lee Rink Partners. Joe, your line is now open.

Thanks so much, and congrats on all the progress. NERCRIN seems to be doing quite well with the Crenicity launch. I was just wondering, how does that figure into your thinking about the pace of enrollment for your Phase III CH studies now, if at all? And are there any particular kinds of patients who are more likely to go on to chronicity commercial versus enroll in a clinical study for at the moment? Does that select for any kinds of patients in your view?

Hi, Joe. Thanks for the question. So, look, I think that the launch from chronicity is a great thing for patients with CAH. and the momentum of that launch shows some of the unmet need that's out there. And in terms of impact on our enrollment in our phase three, either adult or pediatrics, actually, I think it's a positive. In general, it's raising awareness on multiple fronts of the disease. And I think that as another nuance, in general, most of these studies, the bulk of our enrollment has been outside the U.S., not inside the U.S., just because of treatment patterns in the different regions. So, generally, I think it's all positive for patients. And maybe just ask Dana if she wants to comment, or Alan, on kind of the patient population that we're treating.

Yes. Thanks, Scott. I think one, you know, interesting difference between, you know, their indicated population and what we're trying to achieve in our phase three is that we're looking at a broader patient population because the way we look at it is it's sort of a spectrum, and there are patients who have, you know, high A4 and high GCs. There are patients that have just high A4 and are not on GCs, and then there's others with normal A4 and high GCs, we think that all of those patients can benefit from adamelnut. So in, you know, one sense, it's a much broader population. So you know, that is a big distinction and does sort of reflect how we view this particular mechanism of action as addressing, you know, sort of the full spectrum of disease.

Thanks for the caller.

Thank you very much. Our next question comes from Tyler Van Buren from TD Cowan. Tyler, your line is now open.

This is Frances on for Tyler. So, just curious if you could elaborate on the timelines for the IND positions of the TSH and SST3 agonists. Are you still targeting 2025?

Maybe, Steve, you want to give some color on that.

Thanks for the question. Those IND enabling work is all still in progress. we are targeting the end of the year. I don't have particular granularity past that, but that's certainly what we're aiming for for both molecules.

Thank you.

Thank you very much. Our next question comes from Jessica Fyfe, JP Morgan. Jessica, your line is not open.

This is Abdulan for Jess. Can you speak to your comfort level with current consensus numbers for the Paul II's teen launch? Thank you.

I'll let Toby take that one. Yeah, thanks, Scott. You know, it's not typical for companies at this stage or prudent to comment on consensus. We haven't given guidance, so that's where we are right now. We feel comfortable, though, on the launch preparation and the progress we're making with the FDA.

Thank you. Thank you very much. As a reminder, if you'd like to raise a question, please signal we're pressing star followed Our next question comes from Maxwell School from Wilkins Stanley. Maxwell, your line is now open.

This is Selena on for Max. Thank you for taking our question. For the Global CAH Phase III study, what are your expectations around placebo response and any potential impact from different geographies?

Dana or Alan, do you want to comment?

Yeah, sure. I think that we have a pretty ambitious endpoint as we talked about for the adult trial. And we are not really expecting a very high placebo response rate at all. So, again, you know, we're setting it up so that you have to sort of address both the A4s and have a reduction in GCs, the physiologic levels. So, in our mind, regardless of which part of the spectrum of CAH you're in, it'll be very difficult for a placebo patient to meaningfully change where they are. So, you know, that's kind of the way we're looking at it.

Thank you very much. Our next question comes from Yasin Rahimi from Piper Sandler. Yasin, your line is not open.

Hi, team. This is Liam on for Yaz. Just in regard to Palsonify, we were wondering if you plan to provide color on pricing at the time of approval, and then also with, like, your current payer work, how much do you understand about the level of flexibility you might have to price when compared to, like, current SSR injectables?

Yeah, so, you know, obviously we'll be discussing price at the right time after what we hope will be in approval soon. But, Isabel, maybe you want to talk a little bit about the payer side of things.

Yes. Thank you very much for the questions. So, we had continued to make progress in our discussions with payers, and the value proposition continues to resonate and is very positive, the feedback that we are getting from them. They understand that current treatments, particularly SRLs, have a high burden of treatment, and there is significant waste with many of the patients, one-third of the patients exactly, taking more than 13 injections a year. So we continue to partner with them. We continue to reinforce the clinical value of the treatment. And at this time, we are not commenting further on price.

Thank you.

Thank you very much. Our next question comes from Josh Schwimmer from Cantor. Josh, your line is now open.

Thanks for taking the question. I guess, given how much scrutiny there was on the cases of LFT elevation that we're seeing with Adam Elman, can you provide an update on the ongoing experience and whether that's been seen subsequently? And how do you plan on kind of maintaining updates going forward on that liver tox profile and whether it is turning into a meaningful signal or the opposite?

Yeah, thanks, Josh. You know, I think we've said before we're kind of surprised at the scrutiny on that one patient we saw earlier, and we're very comfortable with the emerging and growing experience that we're gaining with it. And in terms of updates on it, I think it warrants updates as the data matures and we have something meaningful to share. We should remind everybody that this is part of a much larger program. We're rolling patients into the open label extension from the phase twos. We're starting to activate sites and we'll be enrolling patients in the adult study and then the pediatric study. And so I think that kind of emerging experience will give people more and more comfort. And if there's a big problem, obviously, we'd have to let people know. So I think no news is good news on that front.

Thank you.

Thank you very much. Our next question comes from Alex Thompson from Stiefel. Alex, your line is now open.

Hey, guys. This is Seth on for Alex. We just had a question about Pulsanify and just how many patients are on the OLE, and how quickly do you expect them to transition to commercial treatment once approved and launched?

Yeah, maybe we'll let... Boy, this could be anybody answering this one, But I will remind you that we have patients all around the world, not just in the U.S. So maybe, Isabel or Dana, you want to comment on that transition.

Yes, I'd be happy to start. Yes, go ahead, Dana.

Dana, why don't you? Go ahead, Isabel.

No, no, I wanted to say yes. Okay, sorry about that.

Okay. You know, the open label extension, as Scott mentioned, is ongoing in numerous countries. And, you know, with the U.S. approval, you know, there will be, you know, we'll have to see, you know, what the outcome of the, you know, regulatory interactions are. But, you know, I think that once the company has, you know, reached a fidufer date and we've had a successful outcome, we can make a decision about, you know, what happens with those patients. And it's really only a small number of the patients that are in the U.S. that would be, you know, sort of potentially enrolled in the commercial drug.

Got it.

Thank you very much. Our next question comes from Gavin Clark Gartner from Evercore ISI. Gavin, your line's now open.

Hey, this is Yachan for Gavin.

Just a quick question from our end. We shared that cohort four of the adult phase two for CAH is going to be down in early 2026. We're wondering if we could also expect any OLE data with this update.

Yeah, I think this is Scott again. But look, I think we'll have a broader update on the whole program. Remember, in addition to that cohort and the OLE, we should be getting deep into then the ramping up of the adult CAH study, the pediatric CAH study, and we'll need to provide some clarity then on the Cushing's disease program as well. So, I think there's going to be a ton of things to talk about around ATU-MELNET in the not-too-distant future.

Great.

Thank you very much. Our next question comes from Rich Law from Goldman Sachs. Rich, your line is now open. Hey, guys.

Good afternoon. How much do you think you can learn based on Atumelan's cohort with only 10 patients? And I assume there's going to be data variability. Is there a chance to adjust the phase three protocol based on what you learn in that cohort for since you're starting the phase three study before you see the phase two data?

Yeah, I think that's a good point. that reminder it's only 10 patients, and we've got quite a few more patients hopefully going into the OLE. But maybe, Dana, you want to talk about just the process around protocols.

Well, sure. As we mentioned, cohort four, one of the interesting questions that we were, you know, trying to understand better is the difference between AM and PM dosing. We've already decided in the phase three that it's going to be PM dosing. I think, you know, the information for that will be useful afterwards, right, in terms of, you know, eventually, you know, potentially trying to understand whether patients need that kind of flexibility going forward. But we are really locked and loaded for the phase three, as Scott and, you know, we have mentioned before, the sites are already getting started and we expect the first patients in soon. So, you know, we really aren't planning on making any changes in the protocol right now.

Thank you very much. As a reminder, if you would like to raise a question, please signal we're pressing star followed by one. Our next question comes from Corey from LifeSciCAP. So, Corey, your line is now over.

Good afternoon, and thanks for taking our questions. When we look to some of the competitive readouts in CAH, the criteria for GC dose reductions were a reflection of maintaining A4 levels within, you know, that 120% of baseline values. However, that was based on the pre-GC dose A4 levels. And when we look to the A4 component in the primary endpoint that you're using for common and balanced studies, that's based off of post-GC dose A4. So obviously A4 is expected to be lower after a patient takes their morning GC dose, but can you just provide a bit of context as to why specifically you selected post-GCA4 as part of the primary endpoint, and how should we be thinking about the clinical relevance of, you know, assessing efficacy pre-GC versus post-GC on interesting diodes? Thanks.

Yeah, I think that's a good question, Corey. You know, just a reminder that I don't think that keeping A4 levels at 120 percent of what might be a very high baseline is all that great of a treatment goal for the person dealing with their CAH. And we believe they should be getting down to normal or very close to it. But Alan, maybe you want to talk about some of those nuances in post and pre-GC dosing. And I'll remind you, Corey, that between the primary and the secondary endpoints, we're looking at both. And just as I always encourage everybody, it's the overall profile of the drug that's really important in addition to the primary endpoint.

Yeah. So, you know, it is true that when you administer glucocorticoid, you would expect in this patient population for the A4 level to go down. And, you know, that is kind of what the regulatory precedent that was set in the chronicity trials established. That is the optimal time to measure A4 with respect to looking at the trough level of androgen exposure with the treatment regimen to include the drug plus the glucocorticoid. We use that partly because it's a precedent, but also because it helps to facilitate variability assumptions for sample size calculations. With those assumptions, we know we have a very well-powered trial here at phase three.

That's helpful.

Thank you very much.

Our next question comes from Brian Skorny from BADD. brian your line is now open hey guys uh this is charlie on for brian thanks for taking the question uh we just kind of wanted to dig in a little bit into what you anticipate distribution looking like and along those lines if you anticipate help donify getting captured in data services like ikezia for example thanks uh isabel you want to respond so i couldn't hear the question west oh sorry give me one yeah so i was wondering uh just what you anticipate distribution looking like for

pal sonify and if you anticipate it getting captured in data services like icuvia for example yes thank you for the question yes we we had created our distribution system and it's going to be a closed distribution system at this point, so we are now planning to make that data available. It will be blocked. We want to make sure that we are able to track the launch and see the uptake in different segments that is not going to be widely available.

That's helpful. Thank you.

Thank you very much. Our next question comes from John Warbin from Citizens. John, your line is not open.

This is Catherine on for John. I just have a quick question about Cushing's disease. And just if you could provide a little bit more color on kind of discussions on what potential endpoints you're looking at and kind of how the endpoint would differ for your mechanism versus kind of some of the other drugs that have been approved in the education. Thank you.

Alan, you want to take that?

Yeah, so the primary endpoint for Cushing's disease trials generally is normalization of 24-hour urine-free cortisol excretion. This is a measure of integrated cortisol exposure over a 24-hour period of time. And approvals are usually based on the proportion of patients who achieve normal urine-free cortisol. I mean, I think ectomelment is uniquely situated here in several ways. One is in our trials to date. Again, we're running a single center trial at the NIH and we will be starting larger trials soon. But what we're seeing so far is a very rapid normalization of urine-free cortisol in pretty much all of the patients tested so far. The rapidity, I think, is unprecedented. And the treatment duration of the NIH is 10 days. And within less than 10 days, we are seeing normalization of urine-free. So I'm very excited to expand these trials to increase the duration of treatment and to enroll more patients to hopefully see this as a consistent finding. And if so, I think we have kind of a real new level of treatment for Cushing's disease here.

Thank you very much. Our next question comes from Andy Chen from Wolf Research. Andy, your line is now open.

Hey, Brendan on for Andy. You stated earlier that acromegaly patients see endos two to four times a year. which could lead to a slower start to the launch. But shouldn't this approval draw patients to see their docs regardless of their cadence throughout the year? And further, when do you expect patients to start flowing in?

Yeah, thanks.

And, you know, I think this is almost something we can answer for ourselves just based on personal experience of, in most healthcare systems, how long it takes to get to see a specialist, which is unfortunate but true. But, Isabel, maybe you want to comment more specifically on the question.

Yes, most patients are visiting their doctor every six months or once a year. Of course, we are working actively in our engagement with advocacy and our activities in patient activation, as I mentioned it before, to get patients to, you know, proactively search for those appointments and move them, but we know that that will take time and that but we are cautious that at the beginning it will take some regular rhythm of patients going to their providers. Our goal is to accelerate it, but we recognize that that will be one of the barriers early on.

Thank you very much. As a reminder, to raise a question. We'll be star-full above one. Our next question comes from David Lebowitz from Citi. David, your line is now open.

Hi, guys. It's Ross Ahn for David. I guess I had a question on Graves' disease. It seems like a TSH antagonist or antagonist is an obvious disease-modifying mechanism, yet other people are pursuing other targets. I guess, why do you think there hasn't been a TSH antagonist successfully developed, and what do you guys think you're doing differently now with that in mind?

Well, this is Scott. I think that this is right in our sweet spot, and you could ask that same question about almost any of our earlier, you know, of our programs. So these are very difficult targets to address. We've built a capability for this over now 18, no, 17 years at Chronetics. But, Steve, maybe you want to comment a little bit on what it's taken us to manage to crack this one as well as some of the other programs.

Yeah, thanks, Scott, and thanks for the question. I do think this is, you know, you look at TSH antagonism for the treatment of Graves and the treatment of thyroid eye disease, and you know that from a mechanistic standpoint, blocking the action of the receptor is the right thing to do if you can make the right molecule. But I think this is, I think as Scott said, this is what we do, you know, for CAH and for Cushing's, the right thing to do is block the action of the ACTH receptor. for the right thing for hyperparathyroidism is to block it as a pth receptor um and so rather than find kind of an end around to to try and get an effect we work to find the right molecules at the right receptors that'll produce the right medicinal chemistry skills and the drug development skills and the you know the understanding of biology and receptor pharmacology you know, to kind of put all those pieces together to find the right molecules.

Thank you very much. Our next question comes from Douglas Sell from H.C. Wainwright. Douglas, your line is not open.

Hi, good afternoon. Thanks for taking the questions and congrats on the progress. I'm just curious, in terms of the balanced CAH study, in terms of Part B for the GC tapering, I'm just curious, will that replicate what we see or the same protocol that will be used in COM-CAH because I believe there's sort of GUDUCO-GC reduction periods followed by sort of GC-stable periods. And I think it takes place over two sort of periods. Is that what you're going to be doing in the balanced CAH study as well? Thank you.

Yeah, Dana or Alan, do you want to take that on study design?

Yeah, thanks. So, I think what you were asking, Doug, was about the, you know, the pediatric, you know, phase three part, right? And, you know, what we're trying to do, it's not exactly the same, but we're trying to demonstrate both efficacy at, you know, reduction in A4 and getting, you know, GCs tapered, right? But I think, you know, in the pediatric space, case, you're always a little bit, you know, more, you know, cautious with the kids. And so, you know, we have a little bit more flexibility in terms of how the GC reductions take place. And, you know, I think that that is kind of going to be a little bit, you know, reflected in the mechanisms of how the investigators carefully titrate them down. But what we're looking for is, you know, to get patients to normal A4 and then, you know, keep trying to titrate them down.

And is there, is it set in the protocol for investigators to titrate down or is that investigator discretion?

Well, that is the objective of the protocol, is to get them to reduce the GCs as much as they can.

But there's no time when they have to achieve it by, or, you know, by 25 weeks or something of that order.

Yeah, there is an end point to the trial. And so they're expected to be on stable GCs for a four-week period before the end of the trial.

Okay, great.

28 weeks, so from 24 to 28 weeks, it's stable.

Okay.

Thank you very much. Our next question comes from Rohan Mather from Oppenheimer. Rohan, your line is now open.

This is Rohan from Leland. Thanks for taking my question. On that to melanin, just given the timelines for the adult and pediatric trials, how does plan to manage the progression towards NDA submission and labeling discussions while incorporating both those, the data from both of those studies down the line? Thanks.

Dana, you want to take that one?

Well, yes. Thanks for the question. And the way that we look at it is we're looking at each one of those as a distinct submission. And so I don't think that we'll necessarily hold one until the other one gets done. So whatever gets done first, which, you know, the phase three for the, you know, adults is, you know, definitely, you know, almost, you know, begun in phase three. So that should be done before the pediatric one. And so the way that we look at it is we will submit that. Hopefully it will be successful. And then we'll do, you know, an amendment or a supplement to add the pediatrics to it. got it.

Thank you.

Thank you very much. Our next question comes from Catherine Novak from Jones. Catherine, your line is not open.

Hey, good afternoon, guys. Thanks for taking my questions. I'm just curious on your thoughts on PALP2s, a team in surgically naive patients based on the AAC presentation. You know, is there a market here? Is there a significant number of patients to do orgo-surgical resection?

Thanks, Catherine. Let me let Isabel answer that one.

Thank you. Well, as you know, we have a label that we'll, you know, aim based on Pathfinder 1 or Pathfinder 2, if pending the FDA review, look at naive and also switching patients. When it comes to presurgical patients We are very excited about the data that we were able to present at Endo, and we also believe that there is an under-need, but at this time, we are not actively considering that segment. We believe that if it's agency, that there is an opportunity and pending our label, that might be an opportunity in the future.

Okay. Got it. Thanks.

Thank you very much. That was our final question, and that concludes today's call. We'd like to thank everyone for joining. You want to disconnect your lines.
