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 LIN

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, Parenteral Sport volume reduction reached a statistically significant 40% at week 24 and the effect was maintained with a 52% volume reduction at week 52. And as shown on Slide 11 all patients were clinical responders defined as those achieving a parenteral support volume reduction of at least 20%. At week 52 seven of the nine patients, or 78% achieved at least one day of parenteral support. At week 52 patients gained 2.1 days off for parenteral support per week compared to a main of 5.2 days per week at baseline. A significant improvement which allows patients more independents. Apraglutide goods have was found to be well tolerated with an acceptable safety profile. These data are a strong testament to the durability of the effect of apraglutide on improving intestinal absorption and reducing parenteral support dependency in CIC patients and reinforces our high conviction in the Phase 3 study. Moving to Slide 12. The STARS Phase 3 study is the largest GLP-2 trial ever conducted in SBS-IF with 164 patients and has been designed to evaluate efficacy in both stoma and colon-in-continuity patient population. The STARS Phase 3 study's primary endpoint which includes some in CIC patients is relative change from baseline in weekly parenteral score volume at week 24. We believe apraglutide has the potential to improve the standard of care as the only once-weekly GLP-2 therapy for SBS-IF if successful and approved. We're looking forward to the top line data expected in March 2024 and we'll keep you updated as the study continues to advance. On Slide 13 is an expanded view of our portfolio. In addition to evaluating apraglutide for sure be syndrome with intestinal failure, we're also evaluating the asset as a potential treatment for patients with graft-versus-host disease or GvHD. Graft-versus-host disease is immunologically mediated and occurs in individuals undergoing allogeneic hematopoietic stem cell transplant where donor immune cells react against the host recipient. The gastrointestinal tract is among the most common sites affected by GvHD and severe manifestations of GvHD or tend to poor prognosis in these patients. Enrollment is completed and data is expected from this open-label Phase 2 study in the first quarter of 2024. Now the CNP-104 for the potential treatment of primary biliary cholangitis. PBC is a slowly progressive and debilitating rare disease driven by an autoimmune response to the PDC-E2 antigen in which autoreactive T cells destroy the bile ducts. The underlying root cause of the disease. This may result in profound fatigue and pruritus as well as other symptoms and not uncommonly can lead to irreversible damage and scarring and in the liver ultimately requiring liver transplant. As Tom mentioned given the strong science behind this clinical program we had the opportunity to assess peripheral T cells. We completed an early assessment which showed evidence of favorable T cell responses in patients treated with CNP-104 supporting the mechanistic rationale for this asset which we believe could potentially impact disease progression in PBC. We're encouraged by the T cell response and we expect top line data results in the third quarter of 2024. As a reminder the primary endpoint in Phase 2 study includes safety tolerability plus change in affluent phosphates. We're excited about CNP-104 because it is truly precision medicine and it introduces a potentially new game-changing therapy for PBC patients as there are no therapies on the market that address the root cause of this progressive liver disease. Moving on to IW-3300, a wholly-owned Ironwood asset for the potential treatment of interstitial cystitis and bladder pain syndrome. There's a significant unmet need in this area. As this condition affects millions of Americans yet there are very few treatment options currently on the market or in development. We're currently executing a proof-of-concept Phase 2 study which is progressing. We're excited about this program as it is the first time the cross talk hypothesis will be tested in humans and we're proud to be at the forefront of clinical development in this area. Over the past couple of years, we've evolved Ironwood into a leading GI company with a robust pipeline that addresses serious, organic GI diseases with high unmet patient need. We're looking forward to an exciting and potentially transformational year for Ironwood with several catalysts in 2024, highlighted by the top line data from the STARS Phase 3 study in March in short bowel syndrome with intestinal failure and top line data from the ongoing Phase 2 study in CNP-104 in the third quarter of 2024. With that, I'll turn it over to Sravan to review LIN

Thanks Mike, and good morning, everyone. I'll begin on slide 15. In the third quarter, LIN

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 LIN

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 LIN

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

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 LIN

Thanks, Tim. Good to talk to you. I think as we've said already we're excited about the performance of LIN

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 LIN

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.
