5/4/2023
Good morning and welcome to the Insmed first quarter 2023 financial results. My name is Nanduja and I will be your operator today. At the end of the presentation, there will be an opportunity to ask questions. To do so, please press star followed by one on your keypad at any time. To withdraw your question, please press star followed by two. We would request everyone to limit their questions to two at a time. I shall now hand over to Brian Dunn to begin.
Thank you, Nadija. Good day, everyone, and welcome to today's conference call to discuss INSMED's first quarter financial results for 2023 and provide a business update. I am joined today by Will Lewis, Chair and Chief Executive Officer, and Sarah Bonstein, Chief Financial Officer, who will each provide some prepared remarks. Later, they will both be joined by Dr. Martina Flammer, Chief Medical Officer, for the Q&A session. Before we start, please note that today's call will include forward-looking statements based on current expectations. These statements represent our judgment as of today and inherently involve risks and uncertainties that may cause actual results to differ materially from the results discussed. Please refer to our filings with the Securities and Exchange Commission, which are available at www.sdc.gov and on our website for more information concerning the risk factors that could affect the company. The information on today's call is for the benefit of the investment community. It is not intended for promotional purposes and it is not sufficient for prescribing decisions. With that, I will turn the call over to Will Lewis for prepared remarks.
Thank you, Brian, and good morning, everyone. I am pleased to report that INSEMED began 2023 exactly how we hoped it would, with a strong quarter of commercial execution, which delivered 23% revenue growth, while also continuing to fulfill its promises from a research and development perspective. By nearly any measure, The most important pipeline milestone for InnsMed in the first quarter was the completion of enrollment in the Aspen study of rensocative in adult patients with non-cystic fibrosis bronchiectasis. On last quarter's conference call, we reiterated our goal to enroll more than 1,600 adult patients in Aspen by the end of March, which in itself would have been an unprecedented achievement for a study in this patient population, both in terms of overall patient numbers as well as the pace of enrollment. But in reality, we exceeded even that ambitious enrollment target. In total, the Aspen study enrolled more than 1,700 adult patients at more than 460 sites in nearly 40 countries. To put that in context, that is more than 75% larger than any prior Phase III program in this indication and was achieved in a similar amount of time despite enrolling during a global respiratory pandemic. In fact, the number of patients enrolled in Aspen during just the first quarter of 2023 exceeded the entire enrollment of our Phase 2 Willow study. This speaks to the number and motivation of patients seeking solutions for this condition and adds to our confidence in the potential commercial opportunity for Brenzocatib. None of this could have been achieved without the tireless dedication and passion of our Brenzocatib clinical colleagues, who deserve tremendous credit for getting us to the position we are in. Perhaps most importantly, the achievement of this enrollment goal largely de-risks the timing of the readout of the Aspen study, which we continue to believe will be in the second quarter of 2024. This data readout will be a major inflection point for Insumet with the potential to quickly transform the company from one that serves tens of thousands of patients currently to one that could serve more than a million upon Brenzocatib's potential approval as a first in disease, first in mechanism treatment for bronchiectasis. And even that number of patients could be just the beginning. Brenzocatib and the DPP-1 pathway that it targets has the potential to address a host of diseases caused by neutrophilic inflammation, with bronchiectasis representing just the first on that list. And while we're on the topic of Aspen, I hope you saw that with our earnings announcement this morning, we also released on our website the baseline characteristics of the participants in the Aspen study. To put these characteristics into context, we provided a side-by-side comparison of each attribute to that of the participants in our Phase II willow study. Although I won't talk through all of the details on this call, what you will find is that the patients enrolled in Aspen are remarkably similar to those who were enrolled in the successful willow study, including age and gender, as well as, importantly, the percentage who have had three or more exacerbations in the 12 months before entering the study. chronic macrolide use, and other relevant comorbidities such as COPD. All of this adds to our confidence that we have designed this trial to give it the best chance to successfully replicate the results shown in Phase 2, potentially opening up the pathway to the first regulatory filings for Brenzocatib. As you know, the Insumet story goes well beyond the promise of Brenzocatib. In the time between now and the Aspen readout, we expect a series of important catalysts from each of our four development pillars. Let me take a moment to update you on just a selection of these catalysts. Just days from now, on Monday, May 8th, we will host our research day, titled The Future of Rare at Insumet, Functional Genes, AI-Enhanced Proteins, Glowing Algae, and More. This is the moment that we, and many of you, have been waiting for, as we finally will have the opportunity to showcase the depth and breadth of our early stage research efforts, which have been operating behind the scenes and under the radar for nearly two years now. We are extremely excited to unveil multiple proprietary and cutting edge technologies and platforms that we have assembled. We believe these acquired capabilities have the potential to work synergistically to transform the treatment landscape for serious and rare genetic diseases. As we have said before, we expect this early stage research engine to generate at least six INDs by the end of 2025, while accounting for less than 20% of Innsmed's overall spending. We can't wait to introduce you to what we've been working on and to some of the extremely talented people behind that work. If you are not able to join us in person in New York on Monday, we invite you to tune in to the live webcast or replay, both of which will be available on our website. Right after our research day, we will quickly turn our attention to the American Thoracic Society International Conference, or ATS, in the second half of May, where we will showcase new clinical, preclinical, and real-world data in eight presentations across error case, forensicative, and TPIP. This will include real-world error case and NTM lung disease data, as well as subgroup analyses from the Phase II willow study of Brenzocatib in bronchiectasis. In addition to presenting new data at ATS, we will also be engaging with the treating community on disease state awareness as we ramp up activities to support the potential launch of Brenzocatib in bronchiectasis. In the third quarter, we continue to expect to release the top line efficacy and safety results from the ARISE trial for error case in patients with newly diagnosed or recurrent MAC lung infection who have not started antibiotics. As a reminder, the efficacy portion of this data set will include PRO or patient reported outcome data, which is required by the FDA, as well as sputum culture conversion measures which is required by regulatory authorities in Japan and other ex-US markets. This PRO continues to be a topic that comes up often in my conversations with all of you, so let me try to be as helpful as I can. The PRO measures we are using for ARISE and ENCORE consist of two separate scores. The first is focused on respiratory symptoms. These questions are taken from the respiratory domain of the Quality of Life Bronchiectasis Questionnaire. The second score is based on questions focused on fatigue-related symptoms and comes from another existing questionnaire called PROMIS Fatigue 7A. Both of these PROs have been validated in other respiratory diseases and shown to be sensitive to patient symptoms, which is why we have chosen to use them as a starting point in our trials. At this point, We don't know if all of the questions or just a subset of them will prove to be sensitive to changes in patients' symptoms in the MAC setting. The ARISE study, although not powered to show statistically significant differences between trial arms, is designed and sized appropriately to help us validate a respiratory PRO and a fatigue PRO for use in patients with MAC and to provide us with learnings about the questions that are most informative clinically. For example, if there is a specific respiratory related question that shows no change in either trial arm, even while some patients are reporting overall improvement in breathing symptoms, then we might conclude that the question is not especially meaningful. These types of analyses could result in certain questions being prioritized or deprioritized in how we ultimately calculate the PRO scores. within the registration-enabling OnCore study. This is just one example of many analyses that we will evaluate iteratively after the readout of ARISE in order to determine the most optimal set of respiratory and fatigue questions to be used in OnCore. After this thorough analysis of the ARISE data is complete, we will then need to discuss our conclusions and obtain agreement with the FDA So we do not anticipate being in a position to share any of these conclusions at the time of the ARISE top line press release. So what are we expecting to show you when the ARISE data reads out? At a minimum, we expect to disclose the following data points. First, we will provide the change in patient scores from baseline to month seven, which is one month after ending treatment. For both the quality of life bronchiectasis and the promise fatigue questionnaires, in the active and control arms. Next, we will share data measuring how much of a change in the respiratory and fatigue PRO scores is associated with a meaningful improvement for patients in terms of their symptom severity. These data will be collected from the entire population of subjects enrolled into the ARISE study and will be used to validate whether these PRO questionnaires are responsive in this population. We will also disclose the proportion of subjects achieving culture conversion within each trial arm. Although we will be looking at the correlation between changes in PRO scores and culture conversion, showing that correlation in ARISE and ENCORE is not a requirement for FDA approval. Finally, we will provide information on the safety and tolerability profile observed in the trial. We plan to schedule a call for the day of the data release in order to discuss any questions you may have. While we're on the topic of error case, let me provide you with two additional updates on the program. I'm pleased to report that the second meeting of the Data Safety Monitoring Board, or DSMB, was held for error case, where it was recommended that both the ARISE and ENCORE trials continue as planned. As you know, the DSMB only reviews for safety, so this represents the most favorable possible outcome. Separately, we continue to monitor on a blended basis, blinded data, the discontinuation rate in the ARISE trial. Encouragingly, this rate has remained consistent with the 15% figure we disclosed earlier in the year, which is less than half of the rate we observed in the refractory setting. We view both of these updates as additional points of validation for the potential success of error case in the broader MAC settings. Finally, a brief update on our TPIP program. Earlier this week, the DSMB met to review the safety data from our ongoing Phase 2 PAH-ILD and PAH trials and reported no safety concerns and a recommendation to continue the studies unmodified. This is, once again, the best possible outcome and an early positive sign for the program. Before I turn the call over to Sarah to walk you through the financial performance for the quarter, let me take just a moment to discuss the error case commercial franchise. We continue to believe error case is a growth story, particularly in the US and Japan. Despite the softness that is typical in the first quarter in the US, due to the impact of deductible and copay resets for Medicare patients, we saw sequential growth in the first quarter in US error case time since its initial launch. We see this as a sign of positive momentum for the U.S. moving forward. In Japan, as we've said before, we anticipate growth may be more weighted to the back half of 23, especially now that the nation has announced it is finally lifting its COVID restrictions. This is reported to begin next week on May 8th. In closing, I am proud of what INSPED has accomplished to date. in the research lab, in the commercial markets, and in the lives of our patients. I am excited by what the future holds as we approach a period when key clinical readouts will reshape Insumet and, I believe, provide us with multiple potential pathways to transition into a sustainable biotechnology company with a future that is even more impressive than our past. I'll now turn the
Thank you, Will, and good morning, everyone. I am pleased to share with you some of the details in SMED's financial performance for the first quarter of 2023. We entered the quarter with $999 million in cash and cash equivalents and marketable securities. This represents a cash burn of approximately $150 million since year-end 2022. Although this level of burn is higher than we have seen historically, We do not expect it to continue into future quarters this year. While we do have some additional costs that are expected to recur, such as the incremental payments related to our newly issued debt, which accounted for approximately $12 million this quarter, the majority of the increase was specific to this quarter, such as our annual employee incentive compensation payout. It continues to be our expectation that our current cash position will comfortably support our operations as we read out the upcoming string of important clinical catalysts from each of our pillars, leaving us with meaningful cash remaining on hand even after the Aspen data readout in the second quarter of 2024. Looking at error case performance for the first quarter of 2023, total net revenue for error case was $65.2 million reflecting 23% growth year over year. On a regional basis, net revenue was $49.1 million in the U.S., $13.2 million in Japan, and $3 million in Europe and the rest of the world. As Will mentioned, despite the deductible and copay dynamics that always negatively impact U.S. sales in the first quarter, Eric Case posted sequential growth in the U.S. compared to fourth quarter 2022. and was up 20% compared to the first quarter of last year. We are encouraged by the continued positive momentum we've seen in the US in terms of enrollment forms and new patient starts on Aircase, which supports our belief that there is still more room for growth for the brand in its current indication. In Japan, Aircase grew 23% this quarter compared to the first quarter of 2022, despite our sales activities being negatively impacted due to persistent COVID restrictions in the country, which have led to revenue coming in slightly below the fourth quarter. As a parallel example, when the U.S. entered a period of strict COVID restrictions in 2020 and 2021, we saw a plateauing of error case revenues while those restrictions were in place, before returning to growth as people resumed their normal activities. We are seeing the first part of that play out in Japan right now, as the recent sequential performance of error case plateauing indicates. As a result, we expect error case revenues in Japan to remain range bound through the second quarter when we expect these restrictions to begin to lift, setting up the second half of 2023 for a potential return to sequential growth for the territory. In addition, as we anticipated, next month a one-time 9% price decline will go into effect in Japan. Encouragingly, this adjustment is on the low end of the expected range that we laid out on our last earnings call and adds to our confidence that Eric Case will be able to achieve attractive growth in Japan in the second half. Finally, Europe continues to contribute modestly to global revenues in line with our expectations. Today, we are reiterating our 2023 revenue guidance for global revenue of Ericase of $285 to $300 million, reflecting continued strong growth for the brand. Let me now turn to a few additional financial items from the first quarter. In the first quarter of 2023, our gross to net in the U.S. were approximately 18%. This is consistent with our internal expectations for the first quarter, which always has higher gross to net than the remaining quarters of the year. On a full year basis, we continue to expect our gross to net will be in the mid-teen range, which is in line with our historical performance. Cost of product revenues for the first quarter 2023 was $13.8 million, or 21.2% of revenues on a percentage basis, which is also in line with prior year's first quarter. Turning to our GAAP operating expenses. In the first quarter of 2023, research and development expenses were $127.9 million, and SG&A expenses were $79.9 million, reflecting continued investment in both our early and mid- to late-stage pipelines, as well as launch readiness activities for Brenzo catheters. Importantly, R&D expenses this quarter included a non-cash charge of $10.3 million, related to the previously announced acquisition of Virtuous Bio. Excluding that charge, R&D expenses for the quarter would have been slightly down compared to the fourth quarter of 2022. In closing, Insmed continues to perform well with strong commercial execution across the geographies where we operate and a solid cash position that can support the business through the upcoming period of important clinical readouts and beyonds. I'll now turn the call back to Will for closing remarks.
Thank you, Sarah. I have never been more excited about the trajectory for Insumet. Our team is energized, inspired, and determined to meet the ambitious goals we have set out for ourselves. We believe we are well on our way to creating the next great biotechnology success story with multiple meaningful clinical catalysts poised to read out in the near term and an early stage research engine that we can't wait to share with you in just four days. I would like to thank the patients who participate in our studies and the caregivers and families who support them, as well as our shareholders, all of whom have placed their trust in us to deliver great things for patients with serious and rare diseases. We don't take that trust lightly, and we are committed to delivering on those promises. With that, I'd like to open the call to questions. Operator, can we take the first question, please?
Operator?
Okay, folks, bear with us one second while we try to find our operator.
Hello, can you hear me?
We can hear you now, yes, thank you. Could we take the first question, please?
Of course. Please limit your questions to two at a time. The first question comes from the line of Jessica Fire from JP Morgan. Jessica, please go ahead.
Hey, guys. It's Nick on for Jessica. Thanks for taking our questions. I had one on the baseline characteristics of Aspen that you recently showed against Willow. I believe in the past that you've said it positive you could possibly address patients with secondary diagnoses of asthma and COPD. Can you just provide a recap of that thinking? And does that thinking change at all with regard to the percent of patients in Aspen with secondary diagnosis of asthma or COPD?
So I appreciate that question very much. I think one of the great hidden second order potentials of BRENZO in bronchiectasis is this phenomena of patients who currently have COPD or asthma as their primary diagnosis. they may well, in a large percentage of cases, actually also have bronchiectasis. As of right now, with nothing approved to treat bronchiectasis, there's little reason for physicians to diagnose it. And so consequently, the literature suggests that there is a good number of these patients who are actually suffering from bronchiectasis either as well or even potentially misdiagnosed as COPD when they actually have bronchiectasis. I want to be really clear on two points, though. The first is that we've estimated the addressable market at the time of launch to be approximately a million patients. Those are patients that are today diagnosed with bronchiectasis as their primary diagnosis and who are already symptomatic with exacerbations. So our medicine and the entry criteria for our trial perfectly align with this population in the U.S., Europe, and Japan. What we're talking about now is the potential to go beyond that million patients to those patients who are comorbid with COPD and asthma. And in the event that our drug is approved for the treatment of bronchiectasis patients who experience exacerbations, those patients who also have COPD or asthma and are experiencing exacerbations could well be on label for treatment of that condition. Let me pause just for a second and turn it over to Martina, who happens to be joining us today.
we've seen in the data yeah so we've seen that patients with COPD or with asthma as a secondary diagnosis ours are definitely an important patient group and we see a strong overlap there with with bronchiectasis the numerical differences that you see between aspen and willow don't really have any relevance from a clinical perspective there's no reason to believe that that there is less risk for exacerbation for these patients than there was before. And so from what we've seen in the enrollment here is really what we have anticipated.
And let me just finish with one other observation. If you look at the literature and just taking the COPD population in the U.S., it's estimated that somewhere between 4% and 54% of COPD patients also have bronchiectasis. There are 20 million people in the U.S. diagnosed with COPD. So when we talk about this secondary population that may be appropriate for treatment with this drug, it is an enormous additional opportunity. We need to begin the work of understanding which of these patients are actually bronchiectatic with exacerbations, and that starts with education. And that's why our medical education effort is kicking off at the American Thoracic Society in just a couple of weeks' time.
Great. And maybe just a quick follow-up. In kind of thinking about these baseline characteristics between Aspen and Willow, I know in the past you've said that because of the time that Aspen enrolled patients during COVID, you potentially had more reliably exacerbating patients. How does that thinking fit in with what we're seeing within the baseline characteristics? Thanks.
So the single most important thing to realize is that the patients that are in this trial, as those in the Willow trial, are exacerbating patients. The entry criteria of the trial required that they have at least two or more exacerbations in the prior 12 months. The fact that we were able to identify those patients during a time when people were sequestered and exacerbation rates generally were going down in this population speaks to both the the prevalence of this population and the very real clinical need. So what we see here is almost identical between Willow and Aspen, and that is a very encouraging point. I know Martina may have some additional comments and thoughts.
Yeah, it is very encouraging of what we see in the baseline characteristics. And I would also encourage you, if you haven't seen this, it's actually a publication from MBARC. And this is patient data from 2015 going to 2022. So we're covering here the pre-COVID era as well as the lockdown period. And these were patients, almost 17,000 patients. And what you see there is what we see in Aspen. And Aspen means high burden of disease that remains. Almost 30% of those patients are defined as frequent exacerbators. So patients that have at least three exacerbations receive the same number that was actually observed very much before COVID came. 26% of these patients are being hospitalized. And the hospitalization rate is what we now see coming back. Even in the anecdotal discussions, and many of them that I've had with investigators and with experts, A consistent perspective from there, what do they see in the clinic? And from Europe to Japan and to the U.S., they have seen pretty much the same picture that they have seen prior to COVID. So what we see in our baseline characteristics reflects really what the data represents on a much larger scale in this patient population.
Great.
The next question comes from the line of Andrea Tan from Goldman Sachs. Andrea, please go ahead.
Good morning. Thanks for taking my question. Well, thanks for the color on Arise. Recognize that regulatory agencies may not require this, but just given your conversations with physicians, how important do you think or are you hearing that it is to correlate the PRO score to culture conversion? Just curious if you think this is a direct link that they would need to see in order to gain, you know, maybe more comfort with the use of PROs.
I appreciate the question. I think the direct answer to that is anytime you can get harmony between various measures, it makes it a much easier discussion. But the important point to understand here is that the physicians, the market access world, this is our experience with the refractory MAC as well, and indeed the regulatory authorities outside of the U.S. are all centrally focused on the ability to eradicate the underlying infection. And so that culture conversion rate in isolation is very powerful. We saw a very good impact in the refractory MAC population as we extend to all MAC-NTM patients continuing to see that ability to not only culture convert, but to do so fast, more rapidly, and to do so durably are three dimensions of culture conversion that we'll be looking at closely. To the extent that that correlates in the abbreviated timeframe we're going to be looking at with PRO symptoms is also a benefit. But I think because it's just a snapshot in time, it isn't necessarily controlling on the interpretation of the elimination of the underlying bacteria. It may, in fact, take more time, for example, to manifest that correlation. And that would be fine. The important point is for approval, if the PRO shows an improving trend, then we are good in the U.S. If we see a culture conversion trend, we're good in Japan and elsewhere. From a market access point of view, there'll be a lot of attention that will continue to be paid on the culture conversion. So I hope that sort of delineates the different measures and how we're thinking about them.
Sure. Thanks so much.
Next question comes from the line of Judah from Credit Suisse. Judah, please go ahead.
Yeah, hi, guys. Thanks for taking the questions. A couple on our case. First, anything you can comment related to retreatment trends, I guess, specifically in the U.S. for our case that you're seeing in the refractory setting, and then hopping over to Japan. Can you give us just a reminder of where the price cut came in relative to internal expectations, and then maybe what the message is from the Japanese authorities on where they see peak ARK sales, if there is any conclusion you can draw from the price cut? Thanks.
Sure. So starting with the retreatment trend question in the U.S., we continue to see retreatment taking place. Of course, the challenge is how do you define retreatment in the context of physicians who use the drug differently? Sometimes they might give a patient a break for a period of time from using the drug. Some physicians like to extend the duration of treatment. Some will shorten the length of treatment, but then retreat more aggressively. So there's a mix out there, and it makes it difficult to interpret this. But there's no doubt that the underlying trend is that we are seeing patients, much as we did in the phase three trial, successfully culture converted, durably so, and then after a period of time, some of them get reinfected with new infections, and consequently are eligible for retreatment and on label. So we'll continue to monitor that. I think all of the trends that we're seeing in the U.S. right now are positive, and that's a notion we wanted to make sure we conveyed today. It really does feel like the U.S. is back. And as you know, the diagnosis rates in the U.S. were lower during the COVID era, and I think there's probably a backlog of patients out there that are getting back in to see physicians, and we'll be looking for those trends to manifest in the coming quarters. As we think about Japan, I'll ask Sarah to address the price cut question in a second, but I will just take the issue of the message from the Japanese authorities. We were all just over in Japan, and I can tell you to a person from a KOL or from a patient or patient advocacy group point of view, there is universal support and enthusiasm for the use of our drug in this patient population. So I think that probably speaks to the reason why we ended up at the low end of the price cut range. But I don't know, Sarah, if you want to add any color.
Yeah, sure. Happy to add some color. Thanks for the question, Judah. So on our last call, we had guided towards a price cut would be in the second quarter, would be high single to mid-teens. So what we're able to report today is that price cut will be in June. So that's end of the second quarter, so that's obviously a positive, and it will be 9%, so on the low end of that range. And as Will said, it gives us a lot of encouragement on the performance we've been able to put up to date in Japan, and it being 20% plus of our revenue on a global basis. The diagnosed rate in Japan is obviously significant, 15,000 to 18,000 refractory patients, and we believe Japan has been and will continue to be a meaningful contributor to global revenue.
The next question comes from Jennifer Kim from Cantor Fitzgerald. Jennifer, please go ahead.
Hi, thanks for taking my questions. I have a few here. Maybe first, to follow up on your comments on the second-order potential for RENSO, do you have any thoughts on how the role of newer biologics like DUPI might play into that opportunity, given the recent data? And is that a tailwind or a headwind in your view, and why?
Yeah, so it's really important to understand that what we think we have with rensocadab, the DPP-1 inhibitor, is unlocking the neutrophil-driven inflammation cascade, right, inhibiting that and blocking that from taking place. It's really the exploration of a new pathway. And so when you think about complement at Alexion or you think about CFTR modulation at Vertex, These are pathways that unlock enormous potential because it's not simply a disease treatment. It's really understanding the biology of how a disease process begins and can be impacted. And from that perspective, bronchiectasis, while the first and most logical and interesting arena for us to pursue, is just the beginning. Within bronchiectasis, there are sort of two layers of opportunity. One is those that are identified as exacerbating and diagnosed bronchiectatic patients today. And then as we discussed, those who are comorbid, perhaps with asthma or COPD, but perhaps with other conditions. There is tremendous overlap in bronchiectasis with NTM as well. And that's what makes this such a powerful second compound for us if it's approved and the trial is successful. We have all of the infrastructure already in place, all of the call points, all of the KOL relationships. It's all there. All we're going to do is expand it to be able to address this much larger population. But when we think about other drugs that are out there, what we've noticed is that there have been several that have tried to think about going after bronchiectasis and have dropped out. So we take note of Fisenra. We take note of others that have explored this possibility and stepped away. So I think the picture here has only gotten stronger in the wake of the success of our trial. We know others who are targeting bronchiectasis have struggled with enrollment. And that, again, just I think speaks to both the enthusiasm among the treating community for our approach, as well as the opportunity that is out there just among the patient need.
And just to remind folks on what we add in the prepared comments, This trial, over 1700 patients, this is 75% plus larger than any other phase three program that has ever been done in bronchiectasis. And we enrolled it in just around the same amount of time in the middle of a global respiratory pandemic. So those types of actions show the medical community's embracement of the DPP-1 pathway and what that could potentially do for patients. We're obviously all very eager for Q2 of 24 to see the data, but we're really encouraged. Martina?
