Jennifer Good
President and CEO
Good afternoon, and thank you for joining us for our third quarter 2026 earnings call and business update. Joining me today on this call are my colleagues, Dr. James Cassella, our Chief Development Officer; Farrell Simon, our Chief Commercial Officer; and David Hastings, our Chief Financial Officer. Dave and I will make some initial comments, and then the team is happy to answer any questions you may have. 2026 is a busy year of execution for the company, and the team is heads down on initiating and executing clinical trials in each of our programs. This includes activating sites globally, focusing on ensuring enrollment stays on track, all while staying aligned with the regulatory authorities. It has been fast paced, but this is the fun part of what we do. Let me provide a brief update on each of our programs. First, our lead program in IPF-related chronic cough. We have initiated both OCEAN-1 and OCEAN-2 trials. We are now approved by all regulatory authorities in each of the countries in which we are conducting clinical trials and the clinical team is focused on getting all the sites activated and screening patients. We will give an update once we reach 50% of the patients randomized in each of these trials. The trials are in early stages and progressing, and we continue to believe we are on track with our previously stated guidance for OCEAN-2, the 12-week study reading out in the second half of 2027 and OCEAN-1, the 24-week efficacy endpoint with 52 weeks of safety reading out in the first half of 2028. In October, we took an important step forward in our non-IPF-ILD cough program by aligning with the FDA on the development plan and next study. The pulmonary division has been very helpful and supportive as we think about how to get the first chronic cough drug approved in the U.S. The discussions have been collaborative and clear. Following this meeting with the FDA, our plan is to conduct a Phase II dose-ranging study with approximately 120 non-IPF-ILD patients to confirm the optimal dose or doses to take forward into Phase III. The protocol is written and will be submitted back to the FDA for any comments. We also have the wheels in motion identifying sites and working with our CRO partner to prepare for study initiation. Recall that these clinical centers will overlap directly with the same sites we are using in our North American IPF Phase III program. When we signed a contract and negotiated budgets for our OCEAN trials, we planned for the fact that we likely would conduct an ILD trial. We are planning to initiate this trial in the first quarter of 2027. We will study 2 doses of Haduvio for 12 weeks of fixed dosing in patients with interstitial lung disease, excluding patients with IPF. We anticipate top line data to be available in the first half of 2028. Remember, the ILD opportunity more than doubles the IPF potential, and we continue to hear about the high unmet need in this population from doctors. In parallel to the clinical work, we are looking at prevalence and epi data to help refine our estimates of the commercial opportunity in non-IPF-related chronic cough. Turning now to refractory chronic cough or RCC, and our LAKE Phase IIb trial. With the 2 competitive drug failures this summer, I have talked more about this program over the past few months than I thought was humanly possible. Let me try to briefly summarize where things stand in the RCC space and explain the upcoming sample size reestimation or SSRE. First, there are no active competitive programs left in RCC or any of our targeted chronic cough indications for that matter. Peripheral-only mechanisms have not been able to withstand the complexity and heterogeneity of cough triggers. It was always our hypothesis that while the peripheral mechanism plays a role in settling signaling, the central mechanism is critical in mitigating the hypersensitivity related to cough. Second, I've been asked about the differences in market dynamics between RCC and IPF and non-IPF-related chronic cough. The reality is that RCC is a significant unmet need in which patients' quality of life is deeply affected. We believe that if our drug can offer relief to these patients, we can figure out the commercial dynamics. We are working on various options around targeting the most refractory patient group, potentially with lower doses, et cetera. In a world where it all starts with the patient, RCC is a severe chronic cough condition with no good treatment options. There have been numerous examples of brands such as Dupixent successfully navigating payer dynamics in larger follow-on indications. Finally, as you know, drug development has been very challenging in RCC because of the heterogeneity of patients with chronic cough as well as the placebo effect. We believe we have distinct advantages with our dual central and peripheral mechanism and the demonstrated evidence that our drug works broadly across cough counts. However, we are mindful that there have been very few positive trials. So as we design the Phase IIb LAKE study, we built in a sample size reestimation or SSRE, to account for variability in the patient population, placebo effect, et cetera. Let's just recap the analysis. Once 50% or 50 patients complete the trial, an independent stats team outside of Trevi will look at the unblinded data and confirm powering assumptions at that point in the study. Essentially, we will get 1 of 3 answers back with no corresponding data so as not to unblind the trial. The 3 potential answers are: 1, the trial to date has at least 80% power, and we should continue with the original plan of enrolling 100 patients. 2, the trial is showing a conditional power range of 40% to 80%. This means the drug is working, but there is either more variability or less of an effect size than our original assumptions. We then will upsize accordingly up to a maximum of 152 patients. It is not all or nothing with the upsize. It is a proportional upsize from 4 to 52 patients meant to restore at least 80% conditional power. A little color on what that means. The effect size in this conditional power range represents an effect size of approximately low 20% range to 30%. Just to be clear, effect size is defined as drug effect less placebo. A 20% to 30% effect size is clinically meaningful and could have a significant impact in a world where there are no good options. And finally, the 3rd option for the SSRE is futility. The conditional power at the time of analysis for the trial would be below 40% and suggests futility for the fully completed trial. In light of the fact that the study will likely be close to fully enrolled and there are no competitive programs left, we would plan to finish enrollment based on the original sample size of 100 and look at the data. So to wrap up this SSRE discussion, the SSRE design means that a nonfutile result is a clinically meaningful benefit in cough reduction and upsizing the trial slightly is to ensure that clinical meaningfulness is statistically significant at the end of the study. We estimate we will have the results of the SSRE in the early part of the first quarter and have reconfirmed our guidance for full trial results in the second half of 2027. Finally, last month, a number of chronic cough patient advocacy organizations teamed up to hold an externally led patient-focused drug development or PFDD meeting with the FDA to discuss the disease burden of chronic cough. Patients told their stories of the impact on their lives, and their experiences exemplified the burden of chronic cough across IPF, ILDs and RCC patients. 1 ILD patient stated, cough is the single greatest thief of my quality of life. This meeting represents a meaningful engagement with the FDA in raising the need for effective and safe therapies. The results will be released in 2027 in a voice of the patient report. We are pleased by the focus of the FDA on this significant unmet need. In closing, we are focused on executing against our plan of becoming the leader in chronic cough. With the recent competitive failures in RCC, we are alone in all 3 of our cough indications and have the potential to be a first-in-class therapy in very big markets. We believe if we are able to execute against our current plan, we can create meaningful value for patients and in turn, significant value for our shareholders. I will now turn it over to Dave for his remarks, and then we are happy to answer your questions. Dave?
DH
David Hastings
Chief Financial Officer
Thanks, Jennifer, and good afternoon, everybody. My remarks today will focus on our most important financial metric, which is our cash position and the runway it provides. We ended the third quarter of 2026 with approximately $299 million in cash, cash equivalents and marketable securities. Importantly, we are well capitalized to execute on our development plans as our cash runway extends into 2030. This allows us to fund our clinical trials to key value inflection points, including our lead program in IPF-related chronic cough through potential FDA approval. As Jennifer mentioned, we recently completed a positive FDA meeting where we got clarity on the clinical trial pathway for our non-IPF-ILD-related chronic cough program. So with that feedback, our current cash runway includes funding that program through top line data in our upcoming Phase II trial. Additionally, our current cash resources will fully fund our ongoing Phase IIb LAKE trial for the treatment of patients with RCC. The planned spending of these cash resources also includes pre-commercial activities, but does not include any expenses related to the commercial launch of Haduvio or a Phase III clinical trial in RCC or non-IPF-ILD. So with that, I believe we are well positioned to execute our clinical trials with sufficient funding through critical data points. Operator, we can now open the call for questions.

[Operator Instructions] And our first question comes from the line of Roanna Ruiz of Leerink Partners.
RR
Roanna Clarissa Ruiz
Analyst · Leerink Partners
So I was curious, can you give me more color on your ILD chronic cough meeting with the FDA? Did you achieve all your goals going in? And are there any trial design features that we should think about for the Phase II dose-ranging study that are particularly important for setting up the value proposition in this indication?
JC
James Cassella
Analyst · Leerink Partners
Roanna, this is Jim. Thanks for the question. So we had a very positive and very supportive meeting with the FDA. I think the key takeaways are really around the design of the Phase II dose-ranging trial, which will look very much like the CORAL study that we did to really launch the IPF program. 1 difference being that this will be a longer trial that will really support a more fully Phase III program. So I think the dose-ranging part of this is really to understand in this other ILD population that we have the same parameters for dosing and dose selection. So I think we had really nice alignment on what we need to do there and nothing out of the ordinary. I think just basic show me the data and show me the doses that are really working in this particular population.
RR
Roanna Clarissa Ruiz
Analyst · Leerink Partners
Makes sense. And then thinking ahead to a potential Phase III program in ILD chronic cough, any ideas on where you might land? Would it be a single Phase III or any insights coming out of your interactions with the FDA?
JC
James Cassella
Analyst · Leerink Partners
So I think there's another thing that was -- we had some dialogue on. I think because we want to take into a fact that -- into account the fact that this is a follow-on to the IPF program. This will be an sNDA regulatory submission pathway. We'll be building on the data that we have from the IPF-ILD population to support the non-IPF-ILD population and that program going forward. The beauty of our approach here and the alignment we have with the FDA is to take this stepwise to help them understand what's needed here and for us to understand what they're looking for. So the Phase II dose-ranging study is really to identify the doses, get experience in this patient population, build that on top of our findings and our observations with the IPF population and then design the most efficient, hopefully, and I think realistically, 1 Phase III trial that will bring us to support the sNDA for non-IPF-ILD.

[Operator Instructions] Our next question comes from the line of Annabel Samimy of Stifel.
AS
Annabel Samimy
Analyst · Annabel Samimy of Stifel
So just to follow on the ILD study, obviously, it looks very much like the IPF study. I'm wondering if the FDA has asked you to do anything more? Or have you baked in any other subgroup analyses with this population given that it's a little bit maybe more variable than the IPF population? Are you looking to identify different subgroups with your trial? Or is it just not capable at this -- not possible at this stage?
JC
James Cassella
Analyst · Annabel Samimy of Stifel
Annabel, Jim again. Thanks. It's a great question and one that we had a really good dialogue with a number of the KOLs in this space because it is a diverse population. It's more heterogeneous than IPF. IPF is that part of the ILD world that is really a more unified type of population. But when we get into non-IPF, there's really over 100 different conditions that are involved there. But the underlying condition, the fibrotic lung disease is a common thread among all of these patient groups. So we're going to capitalize on the fact that they have this underlying lung condition, a certain amount of fibrosis as well as the cough. So I think that is the common thread for all of these populations. We've had a good dialogue with the KOLs, and I think that's the approach we're taking in this because it's really hard when you look at all the different subgroups, some of them are smaller, some of them are larger. But really, we're going to go to the fundamental of the disease here where the belief is that the lung fibrosis is really a significant underlying condition for the cough, and that's going to tie all this together.
JG
Jennifer Good
President and CEO
And the FDA did not focus on subgroups, right? They really -- Annabel, we're focused on the fibrotic lung, so yes.
AS
Annabel Samimy
Analyst · Annabel Samimy of Stifel
All right. That's helpful. And just 1 question on RCC. I guess the SSRE slipped just a little bit to the first quarter. So I'm just wondering with enrollment speed, I'm surprised. Is it slightly slower enrollment because of -- I didn't expect it to be slower enrollment because of some of the failures out there. And are there any options to increase powering beyond the 152 if you seem to be falling at the low end of the range? Is there any possibility there in terms of clinical effect size?
JG
Jennifer Good
President and CEO
So I'm going to start, and Jim, you can add. I think, Annabel, this was always going to be -- our time lines always showed December. So when you say slip to Q1, it's early Q1. We're sort of talking about weeks here with the holiday. So just to put it in context, it was always a little tricky because it was December. So it didn't take much and you sort of fell into January. As far as is there any opportunity to go above 152, and Jim, you can comment on this. But we won't know in the 40% to 80% range. We'll only know that it's X, and you should upsize Y. I mean we always overenroll a little bit, but no, we're not going to try to chase efficacy here. We're going to follow the recommendation.
JC
James Cassella
Analyst · Annabel Samimy of Stifel
Yes. And Annabel, I think that we went in with powering assumptions. This is our first parallel arm study in RCC. We learned a lot from the RIVER study, which was the crossover in RCC, and we learned a lot from the CORAL study in terms of the IPF parallel arm study. I think the key here is that we are powering sufficiently. This is a little bit of a statistical adjustment given the effect sizes that we saw previously. So we'll take it with 80% power, which is appropriate for a Phase II study. So if we can get back up there, that's the end we'll go with.

[Operator Instructions] Our next question comes from the line of Maxwell Skor of Morgan Stanley.
MS
Maxwell Skor
Analyst · Maxwell Skor of Morgan Stanley
So beyond confirming powering, would the SSRE outcome change how you plan for RCC overall, for example, the target patient segment, Phase III sizing or whether to partner the program?
JG
Jennifer Good
President and CEO
We'll wait to look at the full data set. We don't really get much, Maxwell, from the interim other than sort of to confirm powering in the end. So we'll wait for the full data set. I think what's changed here is we're in a world where there's nobody else. And so I think before we were trying to be mindful of making sort of superiority around any competitive programs, but that's changed. So I think we'll take a good look at the data. We'll talk to the agency, and we'll figure out sort of what our Phase III program needs to look like. I think much like Jim described on non-IPF-ILD, we believe this is also an sNDA and may only require 1 Phase III study. As for partnering, I don't think that's probably on the table because we're a single asset company. We're going to want to retain sort of global rights. Now whether commercially, we look at Farrell, you can jump in, co-promotes or anything. I think certainly, all those options are on the table. But our intent today is to retain commercial rights for our own program.

[Operator Instructions] Our next question comes from the line of Leland Gershell of Oppenheimer.
LG
Leland Gershell
Analyst · Leland Gershell of Oppenheimer
Just 1 from us on the non-IPF-ILD. So it sounds like the doses that you'll be evaluating here just fall effectively in line with what you have looked at historically in cough. And I'm just wondering maybe for Jim, do you think that there's any biology that could lead to differences in response in that dose range versus IPF-ILD? Obviously, a lot of variability in the biology and the diseases of the various other non-IPF-ILDs. Just kind of curious your thoughts there on kind of dose response in that non-IPF-ILD.
JC
James Cassella
Analyst · Leland Gershell of Oppenheimer
Yes. No. Thanks, Leland. It's a great question and actually one that we were all very interested in, especially the FDA because it's all about doing definitive dose ranging. I think you can imagine that we have IPF, which is a very severe and terminal population. This may be maybe in the eyes of some a little different than that more IPF, more severe population. So there's a possibility that you could see something working maybe a little bit better at the 27-milligram dose trend. However, I think when we talk to the KOLs, their belief is that this is all being driven by the fibrotic lung. So this is really a study to demonstrate what we have and probably see something along the lines of what we saw with IPF. But I think that's really -- it's a show-me stage to make sure that we have our doses right. So I don't think we have a different expectation for ILD, but I think we'll get some good answers out of this.

Our next question comes from the line of Ryan Deschner of Raymond James.
RD
Ryan Deschner
Analyst · Ryan Deschner of Raymond James
On the progress. I'm curious what you've been able to learn from the failure of GSK's Phase III program with camlipixant that could be helpful in the execution of the LAKE trial or in a subsequent Phase III program for RCC or impact how you're thinking about the upcoming SSRE update?
JG
Jennifer Good
President and CEO
Yes. Thanks, Ryan, for the question. I think none of the data has been put out. So it's all been sort of through the grapevine, but there's been a lot of stuff drifting around. I would say what I have learned just from investigators and actually from the company itself is I don't think placebo was a big problem here, which is really, as you know, has always been the only thing we really needed to care about. I also think that it sounds like their first trial worked reasonably well. And for whatever reason, their second trial, CALM-2 fell apart. It was the longer trial, but that trial was also upsized twice. So a lot of kind of confounding factors in that. So I think as Jim has warned me about from the very beginning, we're better off to follow our own data because there was a lot of extenuating circumstances around those trials. I think they were trying to sort of enrich for this greater than 20 coughers. They upsized the trial twice. They sort of took over the development program midstream. There was a lot of challenging aspects of that. So I think, Ryan, we'll run our Phase IIb, hopefully now the dose. And then I'm hoping that we don't need as big a trial as everybody else has had to run because our effect size will be bigger. So that's kind of what we know. I think there's also the [ Nospan ] program out there, some people are aware of. That drug just didn't work. I've seen all the data. It didn't work in IIa, and I think they sort of enrolled 400 patients to show it didn't work in Phase IIb. So I don't think -- I don't know, Jim, there wasn't anything I really learned out of that trial that was really all that enlightening either.
JC
James Cassella
Analyst · Ryan Deschner of Raymond James
Yes. I think the key, Ryan, is that we've designed the LAKE trial to really give us the information we need to have. I think given our experience with chronic cough with IPF and with the RIVER data, we can drive our program based on our own results, and we know that we really need to keep the control over the centers we pick and the patients they pick, and we're all over that.

[Operator Instructions] Our next question comes from the line of Kaveri Pohlman of Clear Street.
UA
Unknown Analyst
Analyst · Kaveri Pohlman of Clear Street
This is Wayne on for Kaveri. So based on our conversation with some investors, there remains some concerns around the ultimate size and durability of the RCC market. So how do you think about those concerns? And what commercial initiatives and market development efforts do you believe will be important to drive physician awareness, patient identification and successful uptake of Haduvio following approval?
FS
Farrell Simon
Analyst · Kaveri Pohlman of Clear Street
Yes, Wayne, this is Farrell. Thank you for the question. So when we look at the RCC market, right, I just want to go back, we're an IPF-ILD-led company. And so when we're focused on building the market, and we've already started those efforts with our unbranded campaign, we're -- we've approached, I think, 93% of pulmonologists that we've already touched talking about the burden of chronic cough in that disease. When we look at the future potential of the RCC market, we'll do our proper market sizing of that market. But we estimate the severe portion, those who have failed other therapies and aligned with our inclusion/exclusion criteria of being diagnosed for greater than 1 year, that really narrows that market to around 1 million patients. And those are the patients that are going to be seen by pulmonologists primarily. So we're still focusing all of our efforts on pulmonology. And as we look at just further market development, that is further off in RCC, right? We are solely focused on developing that IPF and ILD market currently.

FS
Farrell Simon
Analyst · Debanjana Chatterjee of Jones. Your line is now open
Debanjana, this is Farrell. So we'll get the dose from that study. It's part of the reason we're testing the 27 milligrams once a day. If we end up in that range or lower, it doesn't necessarily even have to be a once a day even if we get into really low doses in a twice-a-day delivery, we could still do that. We have work to do there in order to refine what we get out of the trial and really understand how that could impact IPF and ILD because one of the things we don't want to do is cannibalize the pricing in those indications.

JG
Jennifer Good
President and CEO
Yes, John, thank you for that question. That's been a big effort and focus around the company this year. I mean we've always thought about it, but there's been a concerted effort. You'll see in our earnings release we just put out that we actually did get another patent issued around dosing in hepatically impaired patients in non-IPF-ILD. That would take that protection out to 2041. So fundamentally, our patenting strategy is method of use patents. We're trying to get the base patents in place for each of our indications. That takes the protection through 2039. And then beyond that, we're filing essentially different dosing claims that have come up through the work Jim is doing and different claims in the label, and we're having good success getting those issued. So yes, we made some progress on that this quarter.

BF
Brandon Folkes
Analyst · Brandon Folkes of H.C. Wainwright. Your line is now open
Just maybe 2 for me on RCC. On the LAKE, the sample size reestimation, can you just talk about how do you account for potentially different doses across different responses, a bigger part across the 3 active doses. Is the conditional power assessment on SSRE driven by the 54-milligram arm or the 3 active arms? And then secondly, if an upsize is needed, do you get insight into if this is driven by effect size or variability? And if so, can you help us think about just variability, the scenario there just given you are testing lower doses?
JC
James Cassella
Analyst · Brandon Folkes of H.C. Wainwright. Your line is now open
Yes. This is Jim. So on the SSRE, it is based on the high dose only, the 54-milligram twice daily dose. So we will drive everything based on the analysis of that dose alone. We get very little information from the statisticians. We will know to stay at our current end or upsized by a certain number. We have no read on what the issues are or what may be driving any kind of an upsize. So the whole idea here is to keep us unbiased, and that's what the purpose of this is. It really is a statistical adjustment. So in order not to bias the trial, we get very, very little information. We will know all that at the end of the day, obviously, when the study completes, but we don't get that information along the way.

I'm wondering if maybe you can speak to how enrollment is progressing for OCEAN-1 and -2 and how you would think about timing for an eventual filing in IPF. Would you need to submit the -- would you be able to submit the filing with just the OCEAN-2 data and add OCEAN-1 at a later point? Or do you need both data sets in hand before you can?
JG

I'll comment on the first part of that, Jim, you add any. Things are going well. We have a plan. I think site activations are coming along nicely. We've got enrollment coming along nicely. It's early. We think we've reconfirmed our guidance. So we're comfortable with that as of now. I think I would just add a little color. I've gone to all the investigator meetings that Jim and his team have hosted. There's a lot of excitement and enthusiasm around this clinical trial as you guys probably know there's been a lot of clinical work done in IPF, a lot of antifibrotic work. And I think there's a genuine excitement around having a cough option for people to enroll in. So yes, we're -- I think we feel good about that. What was the second half question?
JC
James Cassella
Analyst · Conor MacKay of BMO Capital Markets
No. Really on the filing strategy is we would report out the trials for OCEAN-2 and OCEAN-1 separately. But we would do a comprehensive integrated NDA filing. So that involves the reporting of each of the individual trials, but there's also integrated safety, integrated efficacy. So those will all come together at the end and be filed all as 1 piece for the clinical portion of the NDA.

2 from us, 1 on ILD, 1 on LAKE. For LAKE, I was curious, could you provide any comment on how your site activation is ongoing and if that remains on track or if that's been completely activated? And then also, how many patients have you actually enrolled? I know you're expecting the SSRE to read out at 50% completion, but I was curious specifically on enrollment. And then on ILD, could you just remind us -- you've had some discussions now with the FDA. We know this is not IPF, but is it still -- what is being excluded from the trial in terms of sort of its basket enabling? And then in terms of your dosing, why not a 27 once daily dose? And is there a certain level of degree of fibrosis or cough that will be needed in this trial?

Thanks, William. I'll take the first part. I'll let Jim do ILD. LAKE, our site activations are on track. Not every site is up and running, but we're a long ways there. That's gone very well. I think the enrollment percentage, our general policy is going to be, we'll let you know when we hit 50%, we'll give updates after that. So we're obviously progressing nicely for having this come sort of early in the year. So when we hit that number, we'll let you know. And Jim, I'll turn it over to you on all the ILD questions.

And I may have missed the last one, so you can remind me. In terms of the strategy on patient selection, it will be based on a certain level of fibrosis. That's going to be the underlying condition here. And we're not looking at it in terms of their specific comorbidities. But the intention is that all of the various comorbidities are eligible for the most part with the underlying fibrosis and chronic cough. I think the last question was -- sorry, you may have to remind me.

What is being excluded? Nobody is excluded, IPF.

Yes. No, for the ILD, I mean, really, nobody is being excluded unless they don't have the level of the fibrosis.

Was there 1 more?

Yes. 1 follow-up there. What is the level of fibrosis? I'm just thinking in terms of -- is this a sort of like a moderate to severe cough trial that you have to have just fibrosis, meet some bar? Or is it there's a certain level of very specific fibrosis in the lungs versus just any that you have to sort of complete or meet? And then dosing specifically, why not a 27 QD once-daily dose?

Yes. So in terms of the level of fibrosis, what the KOLs in this space generally have a floor of at least 10% fibrosis in the IPF, non-IPF world to really establish a sort of a reliable condition. And then they sort of break out based on the HRCT scan, what type of ILD they may have. So we're thinking along the lines of that we would have a minimum of about 10% lung fibrosis and without any particular pattern. So that sets the floor for us, but that's pretty much what the experts agree would be establishment of an appropriate level of interstitial lung disease, whether it's IPF or non-IPF. So nothing magical there other than setting the floor. Cough count, I mean, obviously, they have to have chronic cough over the period of time. So why not go into a 27 QD dose? Well, because in the IPF world, we saw that the 27 BID dose was our less effective dose. We are making the assumption that this non-IPF-ILD program will follow very closely to the IPF program. We just didn't think that once a day 27 in the ILD space would be sufficient given the data that we have with IPF.
