Thanks, Matt, and good morning, everyone, and thanks for joining us today. As we approach the end of the year, and look back on the progress we've made across our strategic priorities, we are pleased with the strides taken towards realizing our vision to become the leading GI health care company in the industry. As you come to expect from us over the years, we continue to maximize LINZESS by driving robust demand growth and expanding its clinical utility, while generating strong cash flows. We are on track to deliver on our LINZESS net sales guidance of growth between 6% and 8% this year, and remain encouraged about the future growth potential of LINZESS based on its continued strong performance in the third quarter. But importantly this year, we have also strengthened and progressed our GI portfolio in areas of high unmet need. Earlier this year, we acquired VectivBio, including its lead investigational asset appraised in development for the treatment of short bowel syndrome with intestinal failure, which we believe has the potential to achieve $1 billion in peak net sales and extend the growth horizon for our company into the 2030s. We couldn't be more excited about the potential for apraglutide and just a few weeks ago at the United European Gastronterology Week we presented positive final 52-week data from the Phase 2 STARS Nutrition study in short bowel syndrome with intestinal failure and colon in continuity which were featured during a late-breaker oral presentation. We believe these data highlight the potential for apraglutide to be the best-in-class GLP-2 analog for the whole spectrum of patients in short bowel syndrome test failure, including those with colon in-continuity and reinforces our high conviction for the STAR clinical program. In addition, we're also excited about the progress of CNP-104, a potentially…

Thanks Tom and good morning everyone. I'm delighted to provide an update on our pipeline programs, starting with our progress has in Short Bowel Syndrome with Intestinal Failure or SBS-IF on Slide 8. Short Bowel Syndrome with Intestinal Failure results from severe organ failure, due to reduction in intestinal function below the minimum necessary for normal nutrient and fluid absorption, leading to dependence on lifelong parenteral support or intravenous administration of fluid and nutrients to maintain health growth and survival, SBS-IF is associated with increased mortality, significant morbidity high economic burden and reduced quality of life. On Slide 8 we highlight two distinct patient populations within SBS-IF, that have different metabolic needs. They are stoma and Colon-In-Continuity often referred to as CIC. Patients with stoma often have a higher degree of fluid loss and dehydration, than those with Colon-In-Continuity, since the lack of colon, makes sufficient fluid re-absorption more challenging. These patients are often dependent on lifelong parenteral support and may require parenteral sport infusions for up to 10 to 15 hours a day for seven days a week. Patients with Colon-In-Continuity typically require more nutritional support than absolute fluid volume. Colon-In-Continuity patients due to the presence of a functional colon may have a better opportunity to achieve enteral autonomy which is the elimination of parenteral support altogether. SBS-IF patients with CIC represent greater than 50% of the SBS-IF market and our distinct patient population currently underserved by available treatments. Now to Slide 9. As Tom mentioned, we're excited about the positive final 52-week data from the open-label Phase 2 STARS Nutrition Study. STARS Nutrition is the first ever dedicated study designed to evaluate the clinical benefit of a GLP and BL2 analog specifically in short bowl syndrome with intestinal failure with Colon-in-continuity. As you can see on Slide 10,…

Thanks Mike, and good morning, everyone. I'll begin on slide 15. In the third quarter, LINZESS delivered another quarter of impressive volume growth increasing 8% versus the third quarter of 2022. New-to-brand prescriptions were strong once again, growing 16% year-over-year, reinforcing that patients and healthcare professionals continue to choose LINZESS in a growing market. We believe there is a significant opportunity to reach appropriate new patients, drive additional prescription demand growth, including the roughly six million children and adolescence ages six to 17, who suffer from functional constipation. Since the June FDA approval in this pediatric population we have been promoting LINZESS pediatric gastroenterologists in specific geographies and we'll continue to assess future promotional expansion based on market response from these efforts and we have received great feedback so far. Additionally, at the recent North American Society for Pediatric Gastroenterology, Hepatology & Nutrition Annual Meeting, we met with a number of healthcare professionals. We're excited by the ability to prescribe LINZESS to help this pediatric patient age group which is very encouraging. We look forward to providing updates as we continue to gain more insights into this opportunity which will help inform the investment level and net sales potential in 2024. Next, I'll provide a brief update on the VectivBio transaction. The integration of Ironwood and VectivBio business operations is ongoing and progressing as planned. As we continue to integrate, we remain focused on ensuring business continuity learning from our new colleagues and progressing apraglutide expeditiously. As a reminder, third quarter financial results, notably operating expense and cash flows, include the first full quarter impact from the VectivBio acquisition. We also continue to take the necessary steps to effect the squeeze-out merger under Swiss law to acquire the remaining 2% of outstanding VectivBio shares. We expect this process to be…

Thank you. [Operator Instructions] Our first question comes from the line of Jason Butler. Your line is live.

Hi. Thanks for taking the question, and congrats on the quarter. Just three for me. First one was, can you speak to what if any impact of the label expansion had on LINZESS in the quarter and what you're seeing into the fourth quarter? Second, on apraglutide, can you speak to how improvements in enteral autonomy can help by the pricing leverage or reimbursement? And then just lastly on CMP-104, can you speak to the magnitude of the T-cell responses and how that might speak to the predictive value for clinical outcomes? Thanks.

Yeah. So I'll answer the first one Jason and then I'll hand them over to Mike to get the second and the third. With respect to our 2023 guidance, we're extremely excited to be able to offer LINZESS as the first and only approved prescription therapy for pediatric patients suffering from functional constipation for patients ages six to 17. Our sales guidance of 6% to 8% for the full year includes any impact from the pediatric indication. So it's in the guidance that we've already given. And as a reminder, I think we sated this before, we expect minimal contribution from pediatrics in 2023, as we focus on these promotional pilot programs, and as we kind of assess where we're at and we'll come back at the start of next year when we give guidance for 2024, as to what we think the opportunity size really will be for next year. Mike do you want to take the question?

Yeah. I think the question was on the enteral autonomy for the apraglutide program. I think it's an important question because patients who suffer from SBS-IF and require parenteral support actually have a huge sort of economic burden with their disease because they have to connect themselves to this IV administration of fluid and nutrients, oftentimes as we said for multiple hours in a day for seven days a week. So your question is on enteral autonomy, but we need to remember that even reducing that requirement by a day or two is a significant economic improvement because for these things happen every day it's a huge burden on the patient, but also a financial burden. On achieving enteral autonomy is where you remove completely the need for parenteral support. So that's why enteral autonomy in a way is curative related to parenteral support need, because you no longer need to tether yourself to the IV fluid administration every day. So that's why we think it's a very important consideration in this population. It's also important to understand that prior products haven't really focused on the colon-in-continuity patient population and with our approach we think we have a great opportunity in that population to potentially achieve enteral autonomy.

And then lastly on the CMP

The other part of the question I thought I heard was how does this lend to really the pricing opportunity. And obviously, the value proposition here is very, very strong. One as Mike mentioned this is a really burdensome disease. These patients are very costly to manage. And there's certainly a price point out there are already established with the currently available therapy which is sizable. So I think we're looking at bringing a very strong clinical profile to the table that can basically manage probably a broader patient population in a more significant way. Which obviously is going to put us in a pretty good position as far as where we would enter the market and how we've been enter the market. And maybe Mike, you can talk specifically about the T-cells or?

Yes sure. So it's a good question. And I can tell you what we can tell you, okay from a T-cells response magnitude, I mean remember as Tom alluded to this as well, the reason we did this deal was because of the strong science behind the clinical study, and the chance to assess the potential opportunity by analyzing peripheral T-cells. And recall, this is a peripheral T-cells or look for a disease that's confined to the liver and the biobox, so we completed the early assessment which showed evidence of T-cells responses which really support the mechanistic rationale for CMP which we believe could potentially impact disease progression. But it's a very small unblinded review, which was to determine if we could see this effect on T-cells. So while we're encouraged by the early look and by the favorable findings, we do need to remember that as a reminder the primary endpoint for the Phase 2 has safety tolerability as well. As well as ALFAS really looking forward to that data set to better understand what these changes in the peripheral T-cells mean on clinical endpoints.

Thanks Jason.

Thank you for the questions. Our next question is from the line of David Amsellem with Piper Sandler. Your line is live.

Hey thanks. So, just had a couple of commercially oriented questions on apraglutide. Can you just remind us of the size of the CIC patient subgroup relative to the stoma subgroup? That's number one. Number two is what is the approximate if you have this patient footprint or number of patients that are on Gattex and what's your estimate of the patients the number of patients over time that have cycled through it? That's number two. And then lastly just latest thoughts on how are you thinking about pricing of apraglutide to the extent that a generic of Gattex materializes? Thank you.

All right. So, I think I'll start on the first one and then Mike you can check me on this. Our estimates right now are that the market is essentially 50/50 between stoma patients and CIC patients. The overall market size is rough globally is 17,000 patients. And so -- and it's roughly 50/50 between the two subsets. Number two with respect to the patient footprint on Gattex and the number of patients treated I think our -- again this is all public information and this is to be checked I think our understanding is that it's about 2,000 patients in the US that have been treated by Gattex. And so that's the number that we have. And then third David on pricing. I think Tom already answered this question. I think we're going to -- the Gattex already has a number that's out there. With respect to the idea of a generic I think our view is we're going to come with a very interesting and compelling data package here hopefully in that we'll find out in a few months. But hopefully we'll have a compelling data package to bring to the market and something that will be quite competitive. And then I think on top of that the idea of a generic we don't really see the generics being that viable here. Just there's not that much patient population as you can see from Gattex only having treated 2,000 patients in the United States. It's not an asset for a disease state we think is heavily managed. And there isn't a lot of volume to get from or massive reduction in price in this one.

And I think we also feel that there's probably it's not a real high probability that we'll see a generic. Certainly, there's been and end of file but nobody has really acted on it. And obviously you're going to have to maintain our rems program et cetera. So, this is and there's a lot of mechanics to be able to launch a generic and support the generic. So, I do think that -- and I think when you look at the fact that about 50% of patients discontinued therapy on Gattex within the first year, I think it speaks to the limitations of the drug. And I think, having a drug move from like daily injections to once-a-week injection and a drug that's certainly more potent and longer-acting, really could help a broader patient population particularly the CIC patients.

Thanks, David.

Thank you.

Thank you for your question. Our next question is from the line of Boris Peaker with TD Cohen. Your line is live.

Great. A couple of questions for me. First on 104, just curious why aren't you disclosing the T-cell data? Or maybe another way to ask it is when will we see the actual T-cell data? And then on the apraglutide, if we look at Zelanepaglutide [ph] they showed a 14% of patients that come independent of parenteral nutrition. I'm just curious how important is that in terms of kind of assessing the apraglutide data.

Yes. Thanks, Boris for your questions. On the first question, I'll take it and then Mike can again obviously add additional color. I don't think we ever is -- I think our plan is always to run this trial to completion before we read out any results and we've always contemplated that being a 2024 event. I think at this point in time, we're able to say that we think we'll be able to have a readout in the third quarter of 2024 for the trial. And I think that's when you'll see a more complete data set around the primary endpoint. Mike, I don't know if there's anything else

I think it's fair.

All right. And then the second question do you want to take the second one?

Yes. So for the antroautonomy [ph] question, it's a good question. Clearly there was enteral economy achieved in the CLEPA program that's in the public domain. And you may have seen from our presentation at the UEG meeting, on the SAR nutrition data that we had antroautonomy achieved in the nutrition study as well. Going have to be a higher percentage in the 14% that glepaglutide has published. But nonetheless it's a small open-label study. So we're just looking forward to the Phase III data to better define those outcomes for the patient populations we have in the STAR study.

Great. Thanks for taking my question.

Thank you for your question. [Operator Instructions] Our next question is from the line of Tim Chiang with Capital One. Your line is live.

Thanks. You know, since we're almost done with 2023 and obviously you're doing still quite well with LINZESS. I sort of wanted to get your thoughts on how you sort of look at growth rates for LINZESS for next year? Obviously, you'll probably provide some guidance at the beginning of next year. But how do you guys think LINZESS is situated at this point?

Thanks, Tim. Good to talk to you. I think as we've said already we're excited about the performance of LINZESS right now and the volume growth we've had in 2023. The fact that we're in year 11 of the drug still driving high single-digit demand growth is just a great outcome. And so we think that there are a lot of untreated patients continue to be in a growing market. So we're excited about that. With respect to future guidance I think we'll give guidance at the appropriate time which is next year in the early part like we always did.

Yes. I think, Tim this is Tom. Well it's been really remarkable over the last three years how steady the growth year-over-year has been. And certainly this year has actually been stronger than we've seen in a long time. And what's probably the most important lead indicator here is the volume increase in new-to-brand patients. We're at a 15%, 16% increase year-over-year which is always probably the most -- the best predictor of future growth. So we're certainly not signing up for a 15% increased number for next year. But certainly it's looking very, very strong. And certainly, we're still assessing the upside from the pediatric indication. There's no question we're seeing some growth there. And we really to really understand, kind of, how much we should be investing in that growth opportunity. But I think things look bright and I think we're very confident in what we'll see next year.

Maybe just one follow-up. Obviously, we all get a lot of questions about the GLP-1s but the weight loss drugs. Have you seen any impact? I mean is there any impact to LINZESS from these LP-1 drugs for weight loss?

And Mike do you want to kind of take this?

Yes. I mean yes it's a fair question and we do get questions on it as well on our side. I mean because as you know I mean the GLP-1s are definitely being heavily used. And it's also true that obese patients also suffer from constipation quite regularly too. So there is a lot of [indiscernible] use. I mean the actual impact so that you really want to get at it's hard to nail that down at present, but we certainly appreciate the question. There may be some things there. And we're looking into it but we don't really have a direction right now to how to impact that.

Okay. Great. Thanks.

Thank you for your question. And ladies and gentlemen that will conclude today's Ironwood Pharmaceuticals Q3 2023 investor update conference call. Thank you all for joining. You may now disconnect.
