Presentation
Akash Tewari
Good morning, everyone. For those who just got back from ASCO, I feel sorry for you, I am exhausted as well. But this is Day 1 of our Jefferies Healthcare Conference, something that I am just really excited about. And I have the pleasure of hosting Regeneron. And I am going to hand it off to Ryan for some brief introductions and forward-looking statements and then we’ll get into some questions.
Ryan Crowe
Thanks, Akash and thanks for having us here at the Jefferies conference. It’s always well attended and I am excited to be here. I will start off with some forward-looking statement disclosures. I’d like to remind you that remarks made today may include forward-looking statements about Regeneron. And each forward-looking statement is subject to risks and uncertainties that could cause actual results and events to differ materially from those projected in such statements. A description of material risks and uncertainties can be found in Regeneron’s SEC filings. Regeneron does not undertake any obligation to update any forward-looking statements whether as a result of new information, future events or otherwise. So, we have Bola Akinlade and Brooke Jennings here from Regeneron both in the I&I space since. They are probably new to most of you guys out there. I thought we’d have them do a little intro on what their background and what they are responsible for at Regeneron. So, Bola, why don’t you take it away?
Bolanle Akinlade
Thank you very much, Brian and thank you very much. Akash. Good morning, everyone. I am Bola Akinlade and I am Senior Vice President for Immunology & Inflammation therapeutic area at Regeneron. I have been at Regeneron now for over 8 years, joined in January 2015. I joined as clinical leader for DUPIXENT. Most of you probably out there are aware of. And I lead the clinical team for the first approval in atopic dermatitis. And I have been involved with many of the other indications that DUPIXENT is approved for. So I lead late stage clinical development and my team runs the trials and also gets approval for our drugs that are in the pipeline. I am also responsible for itepekimab, which is an IL-33 antibody that has shown proof of concept in asthma and COPD. And we are in very large trials now, two large trials for COPD with itepekimab. So I will stop there for a little bit and then I’ll let Brook introduce himself.
Brook Jennings
Thank you, Bola.
Bolanle Akinlade
You are very welcome.
Brook Jennings
My name is Brook Jennings. Like Bola, I have been with Regeneron now for a little over 8 years. I joined the organization to lead the marketing efforts across all indications for DUPIXENT. And now I lead the U.S. dermatology business group. And just to give you a quick understanding of where we stand from an overall performance perspective in the United States, as many of you are aware we had our first quarter earnings relatively recently and approximately $2.5 billion in global sales for DUPIXENT, which puts us on an annualized rate of about $10 billion and that is a 40% year-over-year growth, which is also a very healthy growth rate for us. And we are pretty excited about that.
If we look at the individual indications in atopic dermatitis, we are the number one most prescribed biologic by dermatologists. And we are continuing to see robust growth in every age range for which we are indicated in atopic dermatitis. In asthma, we are now the number one product from a new brand prescription standpoint and the number one brand being prescribed for an NBRx perspective by both allergists and pulmonologists and is the fifth biologic to market that is quite a feat as well. In the newer indications chronic rhinosinusitis, we continue to be the market leader as we continue to build and expand that market. And if you look at the other two newest indications, over 11,000 patients have been initiated now with eosinophilic esophagitis and our newest indication prurigo nodularis is continuing to grow as well. If you look at the size of the business opportunity for us, in the United States, there is about 3.5 million patients. Those 3.5 million patients would be across the five indications that we have. So we do have significant opportunities to grow in penetration to that group as well as new opportunities in expanded age ranges for our existing indications.
And then finally, when you think about what we have in the pipeline and specifically from a DUPIXENT perspective and I know we are going to talk about it today, but the very exciting glorious state of the drop recently in COPD represents a significant opportunity and the potential for a significant advancement in a marketplace that has not had any advanced therapeutics literally ever. And then finally, chronic spontaneous urticaria, we will be hearing back from the FDA in the fourth quarter of this year, which has the potential to add another couple of 100,000 patients to our potential opportunity here in the U.S. So very exciting time overall and pleased to be here. Thanks for having us.
Question-and-Answer Session
Q - Akash Tewari
Great. Well, thanks so much for those intro. So, why don’t we start off with COPD? And I think that’s where a lot of the investor focus is on for dupi. And the question you’ve gotten a million times is, are you going to file with one study and what – when you will make that decision when we are really going to hear back from the agency? But I would ask you maybe put yourself in the agency’s shoes and what do you highlight when you go to the agency and you say, you know what this deserves to get on the market with the accelerated approval. What do you think is clinically meaningful for the agency? What justifies an accelerated approval? And then to add on to that, when I do talk to my colleagues on the buy side, there is kind of this view, oh, they maybe able to show mortality data over time with the FEV1 signal. But can you also talk about how long it would actually take to show a signal like that and when a reasonable expectation for even showing up would be from a data perspective?
Bolanle Akinlade
Thank you very much. Lot of questions in there. But first of all, Brook did a really nice job in talking about DUPIXENT, which is really a flagship product in immunology. I mentioned to you that I was a clinical lead for the first indication in atopic dermatitis. And we have had several more indications since then, four more indications, so asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis and very recently prurigo nodularis. DUPIXENT is actually defining the way we look at and treat and diagnose Type 2 inflammatory conditions. Recently, as you said, we had extremely robust results from the BOREAS study in COPD. And just want to remind you, I mean, we went into the study without a Phase 2 trial, okay. But based on the strength of the evidence we had, the genetics data that also guided us and also some preliminary data that we had from patients who had COPD-like conditions, chronic rhinosinusitis and nasal polyp studies went into two large studies the BOREAS study and the NOTUS study. And you have all read about the extremely robust results from BOREAS, the first biologic to actually show significant clinical efficacy. So, 30% reduction in exacerbations, improvement in FEV1, about 80 mls over placebo, patients felt better when it comes to quality of life, the SGRQ. And then also symptomatically that felt better. And when you look at the magnitude of effect, p value is less than 0.001. It’s so, so impressive. I mean no other biologic has done what DUPIXENT has demonstrated. And remember, COPD is the third leading cause of death. So, there is a really, really, really strong unmet medical need. Yes, we have approached the agencies. We will see what they tell us. And it’s not inconceivable that agency approves a drug based on the strength of one data, depending on quality of the data and the strength of the data.
So we are hopeful, we are optimistic. And just remember, there is a huge unmet medical need out there for patients with COPD. Now, you mentioned accelerated approval. This would really not be an accelerated approval if it’s granted, because we do have clinical outcome, okay. It’s not an approval based on the biomarker, okay. This is actually real outcomes, okay. Patients had reduction exacerbations, improvement in FEV1 and they felt better. So maybe you can argue with that, right. Now you asked the question about mortality. And I think that’s a really, really good question. Okay. We don’t have long term – our trials are 1 year in nature. We didn’t see any – there were fewer deaths on DUPIXENT compared to placebo patients. But we really would need much longer trial and larger patients to actually see if there is a mortality benefit with DUPIXENT in chronic COPD – in COPD on a chronic treatment basis. But we are hopeful and we know we maybe able to go into such a trial with our collaboration partner, Sanofi.
Akash Tewari
Okay. Understood. And I will say this. The body language read I have from your team now is there seems to be more confidence than, let’s say, when the initial data came out. I think the initial data said, we will see. Let’s see what the agency says. It seems like your confidence on potentially getting approved with one trial has increased over the last few months. Is that a fair characterization?
Brook Jennings
Let’s leave it at we will have the conversation with the FDA, and we will get our answer. And once we get it, we will share it.
Akash Tewari
Understood. Now maybe on the size of the COPD market. Now there is that cutoff on 300 eosinophils. But the truth is if you look kind of historically with COPD patients, very rare do they actually have elevated eosinophils for an entire year, right? So only about 20%, 30% of those patients can have sustained elevated eosinophils. So as we think about how this market eventually settles out, right, it’s on top of triple therapy in this 300 cut-up on eosinophils. That’s the way that I think the market would start to look at it logically. But when you think about selling these – penetrating this market, thinking about how clinicians would view it, is the 300 cutoff? What really should be thinking about? Or is it really – how do we define Type 2-driven disease? And how do you think that will evolve?
Bolanle Akinlade
That’s a good question. So we would not be the first biologic that would use eosinophils as a cutoff or as a biomarker for treatment. Remember, and to our five biologics use eosinophils as a cutoff for the time of asthma. And they have been fairly successful in showing a treatment benefit. We also know that – and we see this with DUPIXENT also, that the higher the threshold of eosinophils, the more of a treatment benefit you have because the patients are more tied to skewed in terms of the inflammatory milieu. Now about 40% of patients with COPD will be characterized as eosinophilic COPD. Yes, eosinophil counts may fluctuate. But once you declare yourself to be eosinophilic COPD, I think you stay that way. I don’t think you turn around to become a non-eosinophilic COPD patient. So we chose the threshold of 300 based on our experience with asthma trials based on competitors and what they did with their own COPD trials and also based on a genetic data where we have really strong data that correlates COPD and baseline eosinophils. And we see that the strongest association is with the patients who have elevated eosinophils. So we’re very confident that using the thresholds that we’ve had in our trials will actually be very relevant in practice. And now I turn to Brook and see what his thoughts are.
Brook Jennings
Thank you very much I would certainly agree. This is a subset of the overall population. And when you think of the size of that population, we estimate that in the G7 markets to be about 500,000 patients. And that’s going to be patients who have eosinophil counts that are 300 or above. The other thing that Bola gets to play with on a daily basis is our IL-33 molecule as well. So we have a different mechanism of action that may have a broader remits in the COPD space in addition to what dupilumab will have. The one thing I’d throw out there as well, and Bola touched on this, is the experience in pulmonology and allergy ops is the two areas that will be treating COPD most aggressively. They have broad familiarity with the use of biomarkers, specifically eos because they are doing the testing right now as part of the regular routine testing from a blood test perspective, where they get eos results now. It’s not going to be an added burden for them to check that, and it’s going to be a very easy way for them to figure out what patient population will likely be the patient population to more likely respond.
Bolanle Akinlade
I just want to make another comment about eosinophils, okay? So the earliest biomarker approach for eosinophils with asthma and COPD was actually looking at speed of eosinophils, right, where they had a cut of about 2%. And getting speed from patients is actually very difficult, okay? So researchers in the past said, look, what is a good surrogate, okay, in terms of an easily acceptable way of assessing whether a patient has elevated eosinophils in the airway? And they actually came on using a lot of us novels, okay? And it correlates really well with sputum eosinophils. And the pulmonary community and folks that treat patients with asthma and COPD are very comfortable now with using blood eosinophils as that surrogate market rather than having to induce sputum and have measurement of sputum eosinophils.
Akash Tewari
So you mentioned something about COPD, I was surprised, third or fourth leading cause of death. I don’t think that’s something everyone wakes up and things immediately. And do you think about the bolus of demand that might be out in the COPD market? Because you’re going for a well-treated patient population, right? There is a mortality potential benefit to be had. There is this kind of lung – your lung function starts to worsen. After a certain point, you may not be able to recover. So when you characterize the kind of bolus of demand you had for asthma versus what you would perceive the bolus of demand would be for COPD, how should we think about that, right? Could COPD potentially have even more demand out of the gate?
Bolanle Akinlade
I think that’s a commercial question. But I’ll give you – I’m a physician an internist and board-certified internist. So I have seen COPD patients, okay? So let me just characterize the patients we enrolled in our trial. These were patients who were still symptomatic, still exacerbating despite the best standard of care. They want triple therapy, okay, so LABA, LAMA and ICS. So they were optimally treated, and they still had symptoms and exacerbations and felt bad filled ill. So there is an unmet medical need there, okay? And all like in asthma, where we had other approved biologics before DUPIXENT, there is really no bolus that has demonstrated the robustness of the efficacy that we’re seeing with the BOREAS trial. So I’m thinking to myself as a physician, there is really nothing out there for those patients who are still exacerbating despite the best standard of care. And I’ll let Brook answer it from a more of a commercial perspective.
Brook Jennings
Thank you, my friend. So I think Bola touched on it, right? So when you think of the asthma space from a biologic standpoint, as DUPIXENT was the fifth biologic in the marketplace, that bolus had already come and gone in the market, right? So you had the IL-5s in the market, you had the anti-IgE in the marketplace. So it wasn’t as though there was a huge unmet need of patients who have never had the opportunity to have an advanced therapy. Now there was a whole host of patients in the AS market who had failed something that was already there, another one of the advanced therapeutics and then the opportunity to experience what DUPIXENT had as well. So COPD, I look at kind of as a quasi piece between those two. Are those patients out there that are maximized on standard of therapy right now and not having the results that they would like answers unequivocally? Yes. But are all of those patients going to be able to rush out tomorrow and gain access to a biologic if it were indicated? The answer is unequivocally no. So what we do know is we will be working very closely with the allergy and the pulmonology communities to make access as easy as possible for those patients and for those HCPs to be able to access the brand if and when that time comes, which will allow them to more quickly get through that list. So will there be a bolus? Yes. Is it going to be what other markets have seen where you’ve got hundreds of thousands of patients literally waiting on Day 1, not likely?
Akash Tewari
And in terms of step edits because it sounds like these patients are coded, they are identified. You know – doctors know exactly what the subset of patients looks like. When you think about ease of access, how would that compare to, let’s say, you were launching an indication where you didn’t have an inbuilt sales force, you didn’t really have a relationship with these doctors and some level of report with the insurance companies?
Bolanle Akinlade
So, from an access perspective, I think that’s probably one of the unsung situations that has led to the success from a dupilumab perspective. If we think about where we are today in the space for atopic dermatitis from a commercial insurance standpoint, in the United States over patients have access to the drug. Now, access and no step that is not the same thing as we know, but they have access to the product. Across the other markets, we see very similar, very high rates of access. And because we have such great access for existing indications, we would expect there to be a rapid uptake from a payer perspective to allowing patients to gain access to the brand. Now, what hurdles they would put in the place and what step adds they have put in place, we fully expect there will be some. We don’t know what they would be, we would have to work through them with that when the time came.
Brook Jennings
Akash, I just wanted to kind of touch on something you asked about approval based on one study, right. Okay. And I know Ryan will get back to you. Thanks Ryan for that. But I just want to remind everyone, okay. I mean this is probably the first biologic that has been approved for children as young as six months of age, okay. This speaks to the pilot safety that DUPIXENT has demonstrated, okay. It also been – has been tested in thousands of patients in clinical trials. And as our commercial colleagues remind me and tell me we have had hundreds of thousands of patients treated with DUPIXENT, perhaps 600,000 perhaps. And this is an incredibly – compared to most biologics, safe drug. So, when the regulatory agencies evaluate – it’s not a new drug, so remember that, okay. This is a drug that has an established safety profile that the regulatory agencies are very aware of. When regulatory agencies look at approving drugs, they look at the risk and benefits. So, I just want to kind of throw that out there.
Akash Tewari
I really like that. Alright. Now, I was going to ask on IL-33, but I think we are running out of time. Let’s hit on atopic derm, and I get this quite, the question you will often get is, what’s your DUPI number. And I have always said it’s kind of whatever you want it to be. I mean I am not going to sit here and tell you atopic biologic derm penetration is going to be 12% and not 10%, and it just seems kind of silly. But there is a question about Lilly is – it’s one of the best executing companies from a commercial perspective out there. They do have a very solid product profile that is competitive versus DUPIXENT. And let’s not think maybe about percent growth, but in terms of just net patient adds for atopic dermatitis, as you get lebrikizumab on the market, and now you do have a meaningful biologic threat from a very savvy commercial organization. Should we expect net patient adds for atopic derm to change in any way, or whether it’s slightly go down, flatten or actually start to increase?
Brook Jennings
So, thanks for not asking the penetration question that we get 1% extra. That’s one we typically hear. But what I think of the marketplace overall in atopic dermatitis First and foremost, I would say that the most recent entrants, the JAK inhibitors came from two companies that are also very well established and know exactly what they are doing in AbbVie and Pfizer. So, the market has certainly seen additional entrants come. They have certainly seen additional entrants that came with fanfare and additional dollars to spend on helping to grow the overall marketplace. And quite frankly, I actually I am very excited about Lilly coming to market with lebrikizumab because I think that, that will help to expand the market further. When you think of the overall marketplace as an example in the biologic market in psoriasis, that market has significantly more penetrated today than it would have been many, many years ago. And quite frankly, since dupilumab launched in 2017 with the first atopic dermatitis indication, we were the only ones working to expand the market. So, with Pfizer having come to the market, with AbbVie having coming to the market, with LEO having come to the market, the growth rate in the atopic dermatitis advanced therapeutics market has increased. I think Lilly will only add to that. I think that the benefit from a DUPIXENT perspective is when you have the lion’s share of the market, you get a disproportionate share of that growth. So, while a rising tide will lift all boats, I think we will continue to find ourselves in a leadership position.
Akash Tewari
Understood. So, maybe second back and maybe for Ryan, just more generally speaking, people’s obesity numbers just seem to keep going up in models. I think it’s probably implying around $120 million, $150 billion at this point. You guys are renowned drug discoverers. You have the AstraZeneca collaboration, and you have looked at areas that are adjacent in the past. What does Regeneron think about the obesity market? If they were to get involved, where would they try to differentiate? And what could be some timelines we should be thinking about where that story might play out?
Ryan Crowe
Yes, sure. Thanks Akash. It’s we are not lost on us that obesity is a rapidly expanding category with extremely high commercial potential. As you mentioned, I think in 2021, Regeneron discovered the GPR 75 gene, where we have seen small – 650,000 exomes that were screened, only about 1 in 3,000 had a – didn’t have a copy of the GPR 75 unit. And they had 54% lower risk of obesity and where I think on average, 12 pounds lighter than those that a complete GPR 75 gene. So, we found a very solid genetic marker, and we are exploring that through a couple of different ways. You mentioned the AstraZeneca collaboration, and we are working on finding the right small molecule for that. But we also are looking at it from an antibody standpoint internally, and then we are also working on an siRNA approach. So, a couple of different ways of looking at the GPR 75 opportunity, but even beyond that, I think in our pipeline, we have some other mechanisms that are of interest where they could potentially pair with the GPR [ph] to maintain weight loss and also potentially perhaps shift the ratio in terms of fat versus lean muscle loss when you have these weight losses. So, some things to watch, perhaps starting in the second half of this year as we get organized around an obesity approach.
Akash Tewari
Okay. Understood. If I can sneak in maybe just one more question, on high-dose EYLEA, which at least give me quite I would not go there.
Bolanle Akinlade
We got 25 minutes in...
Akash Tewari
Yes. Just one more – so look, just two things. A, the question that I do get from people is, hey, let’s say that you have someone who is on low-dose EYLEA and they look at the data set that you put out with high dose. How does that kind of inform a switch and how does that maybe impact a label that you could theoretically get with high-dose EYLEA? Is that a fair way to characterize it, because to be clear, when I look at the faricimab study, it’s not like that teaches me how to get people per se of another VEGF agent as well. So, any comments on what labeling could look like? And that question, I am sure you are getting from investors right now in terms of the switch.
Bolanle Akinlade
Yes. I think we are not going to comment on potential label, but the review remains on track. We expect a decision by the June 27, PDUFA. In terms of how physicians end up using the product, we think it brings a best-in-class profile, and we will become the new standard of care with hitting non-inferiority on extended dosing intervals of q12 and q16 versus EYLEA at q8. We think that’s a meaningful advantage for patients, for practices and overall for the healthcare system. We do see statistically significant and a higher proportion of patients that had no retinal fluid in the center subfield at week-16 as well as at week-48 in the wet AMD study. So, we are seeing an impact on drying. Overall, I think the product profile is extremely strong, and we are going to go after the entire category, not just patients currently taking EYLEA.
Akash Tewari
Understood. Thank you so much.
