Jan Mikkelsen
Thanks, Tim for this long introduction. Good afternoon, and good evening everyone. And again, an important quarter for Ascendis, as we continue to achieve and approach new major milestones in our journey to file our Vision 3×3, to become a sustainable, profitable leading biopharma company.
Earlier this week, we announced, we had achieved another important milestone as FDA has accepted for priority review, our NDA for TransCon PTH for the treatment of adult patients with hypopara. FDA expects to complete the review of our NDA by April 30, 2023. If approved, we believe we will bring a totally new treatment paradigm to the hypopara community.
Today, we are reporting SKYTROFA US revenue of €12.3 million this third quarter, again, more than doubling our sales compared to last quarter. All patients continues in the Phase 2 ACcomplisH Trial for TransCon CNP, with no dropouts and the longest treatment duration now around two years.
We are looking-forward in the coming weeks to sharing top line results, including early data in children aged 2 to 10 with achondroplasia. In oncology, we will have our first oral presentation at next week’s Society of Immunotherapy in Cancer or SITC conference. We look-forward to sharing our first in-human safety and initial efficacy data supporting our recommended Phase 2 dose for TransCon TLR7/8 agonist.
Last quarter, I made the following statement. We believe that we are on track to become cash flow positive, without the need for additional equity from investors, given the successful launch of SKYTROFA in the US combined with the expected US launch of TransCon PTH in the middle of next year, supported with our strong cash position of around €1 billion. After this quarter, my confidence that we will fulfill this belief has been reinforced.
Okay, let me now share, with you more details on our program. We designed TransCon Growth Hormone now marketed as SKYTROFA in the US to address the unmet medical need that results from children taking daily growth hormone. With a different set of product, we are building SKYTROFA into the global market-leading brand and at the same time expanding the overall value of the growth hormone market.
For this quarter, we reported SKYTROFA revenue of €12.3 million, compared to €4.4 million in the second quarter. As we expect that majority of patients will be on SKYTROFA treatment for at least three to five years, revenue for each quarter becomes the new base for the next quarter.
From that base, revenue continues to grow through the addition of new reimbursed patients. In Q4, we expect to grow the number of new reimbursed patients at a similar level to what we have — saw in Q3 providing a strong base for revenue growth in 2023 and beyond.
I believe with our improved commercial execution we are achieving the goals we set up when we launched SKYTROFA in the US by building on the product strength of SKYTROFA and providing patients with a differentiated treatment.
Over the coming quarters, we will continue to provide updates on all our programs that support our efforts to build TransCon into the leading global brand in a growing growth hormone market.
Let us turn to TransCon PTH, a product candidate we are dedicated to bring to patients as soon as possible. Earlier this week we announced that FDA has accepted for priority review our NDA for TransCon PTH for treatment of adults with hypopara. This is our second product candidate in a row that we are taking all the way from product design to successful regulatory filing.
These patients faced an urgent need for treatment to effectively address their disease. It’s complication and importantly help restore normal life for them. We hope to have a regulatory decision by April 13 of next year from FDA in the US.
Our view of the importance of PTH replacement therapy was confirmed by the recent guidelines update for the management of hypopara. The authors suggested consideration of PTH replacement therapy for HP patients insufficiently controlled due to any one of the following; symptomatic hypoglycemia, hyperosmia, renal insufficient, hypocalcemia or [indiscernible].
They also observed that patients with poor compliance more absorption or who are intolerant of large doses of calcium on active vitamin D might also benefit for PTH therapy.
With the potential to treat all HP patients regardless of disease background and growing dividend for long-term clinical trial data showing durable responses, we believe that TransCon PTH could address this major unmet medical need.
With the US regulatory timeline set and review underway we are focusing on preparation for an expected US approval and launch in Q2 next year. Expanding our global reach for TransCon PTH, we are on track to submit our MAA in Europe and we remain on track to report topline results from our Phase 3 PaTHway Japan Trial, both events expected to happen this quarter.
We are dedicated to further optimizing treatment option for patients. With up to three years of follow-up data from our clinical trial of TransCon PTH, we believe that HP patients on stable PTH doses a once-weekly PTA product could be a potential attractive treatment option. Our data demonstrates that each patient goes to multiple titration and reaches normalization of calcium hemostasis at different times.
We believe once patient obtain that stable doses of daily TransCon PTH that is when they become optimal candidates for switching to a once-weekly PTH therapy with the same mode of action. Our once-weekly TransCon PTH product candidate now in preclinical development is based on the same TransCon technology and PTH parent drug as daily TransCon PTH enabling we believe predictable and safe switching of patients from daily to weekly TransCon PTH.
Turning now to TransCon CNP. We are looking forward in the coming weeks to sharing topline results from the ACCOMPLISH Trial. Our Phase 2 randomized double-blinded placebo-controlled clinical trial of TransCon CNP in children aged two to 10 with achondroplasia.
The ACCOMPLISH Trial was designed to enroll four dose cohort with up to 15 patients each randomized 3:1 active to placebo in sequential cohort of six micrograms per kilo, 20 micrograms per kilo, 50 micrograms per kilo, and 100 micrograms per kilo per week followed for one year on double-blinded base.
A total of 57 patients were enrolled in the four cohorts with 40 of the patients younger than five years old. All 57 patients enrolled completed the blinded portion with no dropouts.
After one year of double-blind treatment, patients transitioned from that dose cohort to an open label extension OLE portion of the trial. As of today all patients had been transitioned to the 100 micrograms per kilo per week dose level and all continue in the open-label extension at that dose.
We continue to see on a blinded basis the same well-tolerated safety profile we reported to you last December with the longest treatment duration now around two years without any dose reduction and 100% patient retention.
The primary endpoint of the ACCOMPLISH trial is annualized height velocity after one year of treatment. The primary analysis is to compare mean annualized height velocity for TransCon CNP cohort to that for placebo-treated patients.
We also plan to report the mean annualized height velocity data for the two patient groups patients aged two years to five years and 5 years to 10 years. In addition to the top-line randomized double-blinded data we also plan to report preliminary data from the open-label extension portion of the study. These data will provide information on treatment impact when treatment from placebo or lower dose up to 100 micrograms per kilo weekly dose of TransCon CNP.
I get a lot of questions about what my expectations are for this filing. First priority, treatment needs to be safe and well-tolerated. From the perspective of outcome, annualized height velocity or call it annualized growth velocity has been validated as the regulatory primary endpoint. Just as with height velocity in other growth disorder trials this endpoint in achondroplasia is dependent on multiple demographic factors.
In particular the age of the patient is a major factor determining the outcome. So the only approved treatment in the US for achondroplasia the analyzed height velocity for patients aged five to 14 was around 5.4 centimeter per year with a greater treatment effect in annualized height velocity for the group 8 to 11 compared to age group 5 to 8. I estimate the benchmark for annualized height velocity for the age group 5 to 10 in the ACcomplisH trial will be slightly lower than the 5.4 centimeter per year, as the ACcomplisH trial has fewer patients in the faster growing age group of 8 to 11 compared to the age group of 5 to 8.
To further evaluate TransCon CNP at 100 micrograms per kilo per weekly dose, we have submitted a protocol to FDA to initiate a global randomized double-blinded placebo-controlled Phase 2b trial in children with achondroplasia from 2 year to 11 years of age. This trial is expected to enroll about 80 patients and measure annualized growth velocity after one year of treatment as the primary endpoint.
Perhaps more important we believe this trial will enroll sufficient patients to analyze additional secondary endpoints, which may help to explain why we see 100% patient retention in our trials. We expect to complete enrollment early next year of this trial. In summary, we remain on track with our Vision 3×3 goal to obtain approval for three endocrinology rare disease products by 2025.
Turning now to oncology. With our first two immunotherapy programs, we are levering both the TransCon systemic technology for TransCon IL-2 beta/gamma and for the first time in human with TransCon hydrogel technology for TransCon TLR7/8 Agonist.
TransCon TLR7/8 Agonist is designed to kick-start the immune system inside the tumor and using our intratumoral hydrogel technology to provide sustained release of the TLR7/8 Agonist over weeks thereby activating the immune system within the tumor microenvironment without systemic toxicity. We recently completed dose escalation and declared the recommended data Phase 2 dose for our TransCon TLR7/8 Agonist candidate.
With a favorable safety profile and early signs of clinical activity observed as monotherapy or in combination with a checkpoint inhibitor, we are pleased that our abstract for top-line dose-escalation data was selected for an oral presentation at SITC the Annual Meeting of the Society for Immunotherapy in Cancer being held in Boston next week.
Our second oncology product candidate TransCon IL-2 beta/gamma is designed to broadly increase systemic stimulation of the body’s immune system. And we believe it has the potential to become a new backbone for cancer immunotherapy.
TransCon IL-2 beta/gamma continues to be well tolerated as monotherapy or in combination therapy and we are seeing promising pharmacodynamic responses and we continue dose escalation. We plan to share monotherapy top-line results later this quarter.
As you can hear there are so many great milestones we have achieved, but also so many, many more in the near-term. With a cash position of €935 million Ascendis is on track to achieve our Vision 3X3. And I remain confident in our ability to drive continued progress.
I will now turn the call over to Scott for additional details and a financials review before we open up for questions.
Scott Smith
Thank you, Jan. So as you heard from Jan, we are making great progress on behalf of the patients across our entire portfolio with SKYTROFA launched in the US and expected to launch in Germany mid next year. Combined with the expected US approval and launch of TransCon PTH in Q2 next year, our advancing pipeline of product opportunities addressing major unmet medical needs and our cash position which is very strong we are more confident than ever in our ability to become cash flow positive and to deliver sustainable profitable long-term growth.
Now on to our results. Today we reported SKYTROFA US revenue for the third quarter more than doubled sequentially to €12.3 million from €4.4 million in Q2. Based on continued growth in the number of reimbursed patients and in line with comments Jan made in May about doubling our revenue quarter-to-quarter we believe we remain on track to achieve fourth quarter SKYTROFA US revenue of at least €16 million based on Jan’s simple algorithm from May, compared to the company-compiled sell-side analyst consensus estimate of €11.9 million. This expected Q4 revenue would then provide us with a very strong base for SKYTROFA U.S. revenue in 2023 and beyond. Growth in US SKYTROFA revenue during the third quarter primarily reflects the strong increase in reimbursed demand. The stronger US dollar provided a minor benefit of approximately €0.5 million.
Now turning to operating expenses. Research and development costs for the third quarter were €97.4 million compared to €58.8 million during the third quarter of 2021. As a reminder, the third quarter of 2021 included a onetime reversal of previous write-downs of pre-launch inventories which reduced R&D cost by €54 million. Overall, this reflects ongoing normalization of our overall R&D cost structure as more programs progress from early through late-stage development and approval.
Selling, general and administrative expenses for the third quarter were €60.7 million, compared to €39.3 million during the third quarter of 2021. These expenses primarily reflect higher commercial costs following the launch of SKYTROFA in preparation for future product launches in the US and Europe. Net finance expenses of €20.9 million for the third quarter included a foreign exchange rate gain of €44.1 million related to translation of our US dollar holdings of cash, cash equivalents and marketable securities to euro.
Overall, we had a net loss for the third quarter of €169 million or €3.03 per basic and diluted share compared to a net loss of €80.3 million or €1.47 per basic and diluted share during the third quarter of 2021. Importantly, we ended the third quarter with cash, cash equivalents and marketable securities totaling €935 million.
Let me now also provide an update on timing key milestones for the remainder of the year. For TransCon hGH, we are on track to complete enrollment in the global Phase 3 foresiGHt trial in adult growth hormone deficiency in Q4. For TransCon PTH, we are on track for a planned MAA submission in Europe in Q4 and for PaTHway Japan, top line results are expected in Q4.
For TransCon CNP, we look forward to sharing the top line results from the Phase 2 ACcomplisH trial in the coming weeks. For TransCon TLR7/8 Agonist, we plan to present top line monotherapy and combo therapy dose-escalation data from the Phase 1/2 transcendIT-101 clinical trial at the SITC conference next week. And for TransCon IL-2 beta/gamma therapy top line results are expected from the Phase 1/2 IL Believe trial in Q4.
As you can see it’s an incredibly busy time for Ascendis going into the end of the year with key catalysts across the pipeline both in endocrinology rare diseases and in oncology. With a strong balance sheet, strong commercial progress and disciplined cost focus, we believe we are well positioned to fulfill Vision 3×3 have the capital to fund our growth initiatives and become cash flow positive.
With that operator, we are now ready to take questions.
Question-and-Answer Session
Operator
Thank you. [Operator Instructions] Our first question comes from Jess Fye with JPMorgan. Thank you for standing by. Your line is now open.
Jess Fye
Hey, guys. Good morning. Nice results tonight. How are you thinking about the potential for the Phase 2b CNP trial to be registrational?
Jan Mikkelsen
That is a great question Jess. And what we believe is the most important part for our Phase 2 trial the ACcomplisH Trial is really to prove that we’re providing a meaningful benefit to the patients that we really are hitting the target product profile that we lay out when we designed TransCon CNP to be in best-in-class product opportunity for treatment as a contemplation. We decided from the perspective that it was not only focused on efficacy, but included everything related to safety, tolerability, the once-weekly dosing profile because we know from 20 years in growth hormone division that a daily dosing is not a function. All that we incorporated and that is the most important part that we want to see from the ACcomplisH Trial.
When you come to the question that if we can some way file on this data, I think it depends what we see in the coming weeks. And I will be much better — some way suited on for me to really answer this question when the data has been unblinded. I have looked at that and we have reported to you. Then I think I will be really, really well-positioned to come with my belief on that end that can be a lot of difference to between different geographic regions, there can be a lot of different elements which basic with someone saying we would like to wait for the 2b trial. And I need to wait to see the data.
Jess Fye
Sorry, I was asking about the 2b could that be registrational?
Jan Mikkelsen
That is what we believe. 2b was basic in the system being developed in such a manner that we hope in the 2b we can come with an explanation why we basically are seeing this 100% retention in our ACcomplisH Trial because we must provide something more to this patient group than just analyze growth velocity. I don’t believe this is the first time I see a trial in achondroplasia where you basically see 100% retention. We hear stories about the patients. We hear when we talk with the caregivers, but we need to quantify that and that is what we hope we can quantify in the 2b.
Jess Fye
Thank you.
Operator
Thank you. Our next question comes from Josh Schimmer with Evercore ISI. Josh, please go ahead.
Josh Schimmer
Thanks much for taking the question. I’ve follow-up on the one from Jessica. I guess, given how close we are to the Phase 2 results for TransCon CNP, why not wait for them to be reported and then design a more fulsome Phase 3 protocol. Why move quickly and why specifically a Phase 2 instead of Phase 3 given how close we are to the data? Thank you.
Jan Mikkelsen
Hey, Josh. This is because we are dedicated to bring this product out to the patient as fast as possible. So what we basic are doing, we are incorporating as in exploratory endpoint and choose menu list of all the element we basically we are providing to the benefit of the patients.
And as soon as we basic have gone through the entire ACcomplisH Trial, really understand what is the key element we are sitting on we basic can relate all one or two of this exploratory endpoint up to secondary endpoint, and therefore that basic can be integrated in the labeling discussion.
So we get so many patients and caregivers coming to us when can we get this product out to the market. And this is why we dedicated to work in this way where we basic are cutting down about one year in development time. Before we look at the data in and discuss it we basic will have enrolled basic all the patient in the beginning of next year, and then we basically can evaluate and basic achieve the same thing.
Josh Schimmer
Got it. If I could ask another very quick one, you’ve indicated that you disclosed new therapeutic category for the TransCon platform by year-end. When can we expect that in what form and what are the gating steps for that announcement?
Jan Mikkelsen
The gating step is basic that we are — on the pre-clinical candidates. We are building up the pipeline, we’re building up what we need to do as we did when we disclosed our rare disease endocrinology pipeline with TransCon PTH and TransCon CNP. We disclosed that in 2015. In 2018, we disclosed our oncology pipeline and we said we will go out and disclose our oncology pipeline, and now we are disclosing our third therapeutic area.
And I can guarantee, I’m really thrilled — a therapeutic area, while locked of really unmet medical need, but also a lot of established target established parent drug with well-function mode of action that really fit our TransCon technology systems. And it will be end of this year potentially at JPMorgan if we want to provide some benefit to where there is a lot of investors at that time.
Josh Schimmer
Got it. Thanks so much.
Operator
Thank you. Our next question comes from David Lebowitz with Citibank. David, your line is now open.
David Lebowitz
Hello. Thank you for taking my question. Additional question on achondroplasia. When we look forward to the data coming out given the cross trial comparisons in the different geographies populations — what is the way that we can benchmark, what we are seeing and what it’s clinical meaningfulness is and how it might actually compare with the competing products?
Jan Mikkelsen
So thanks a lot for the question. Because as I said in the prepared remark this is a question I really get a lot. And what we are — on when we’re trying to benchmark our TransCon CNP to the only approved product here in the US, we’re building on [indiscernible]. We are building on science.
For example, I’m looking on a publication just in front of me. Safety and persistent growth promoting effect of vosoritide in children with achondroplasia, two years results from open dated Phase 3 extension study. Publication is really interesting because there you have analyzed growth velocity, which are the same as annualized height velocity.
And basically you have the annualized growth velocity both from the patient population that got transferred up — got directly on vosoritide, but also the placebo that got transferred up to vosoritide. And in this publication there — direct the annualized growth velocity on an absolute level, because that is how we can compare it.
Then you go back and saying, how can you compare — trial, because there is always dependency on outcome annualized growth velocity depending on different demographic factors. And one of the key element in ACcomplisH is clearly for all the literature there is — is of the patient population.
And this is why as I said in the prepared remarks, we will split it up between two to five, five to 10, because there’s not really any good comparison for two to five, because there is not really data that’s really providing a good benchmark for the two to five. Where we have a good benchmark, mainly coming out from this publication and all the FDA filing documents is for the five and up. And there is clearly dependency if you look on the patient group between five to eight or eight to 11, because there is a much, much more treatment effect with vosoritide in that eight to 11 group. And, therefore, if you adjust for this difference with that you basically can pretty precise go in and make this comparison. And I will have no problem to show my own calculation how I do it. I — share that because it’s built on science, it’s built on peer-reviewed publication and not built on perception.
David Lebowitz
Thank you very much for taking my question. Appreciate it.
Operator
Thank you. Our next question comes from Li Watsek with Cantor. Li, your line is now open.
Li Watsek
Okay, great. Thanks for questions, and congrats on the quarter. Maybe just one on TransCon PTH. Now you have a PDUFA date in April next year. Just wondering, if you can maybe talk about your launch preparation right now and potential synergy with SKYTROFA in the US? And also how should we think about your commercial strategy in Europe?
Jan Mikkelsen
Yeah. Thanks a lot. You said the right word, synergy. Because that was why we built-up a pipeline in rare disease endocrinology with three independent product opportunities where we expect to launch one product after the other within entry [ph] of two years. And that is what we have built 2021 for SKYTROFA, we hope 2023 for TransCon PTH, and we hope the next one coming two years after.
What we’re also doing is that we do a global commercialization. We are dedicated to a global commercialization. Joe that is sitting in front of me, he is responsible for the group here in the US that do commercialization for us. As you have seen, we have different strategies in different geographic regions. We are building up now the long capabilities in Europe ourself. We just opened a German headquarter in Munich. So we are ready to launch from there. We are doing in Greater China through our JV or we can say our ownership in VISEN Pharmaceuticals. So we are also creating value from that perspective.
When we come to the US, yes, there is a lot of synergy. And this is why we have a pipeline approach where we have two things need to be fulfilled for really be checking into our, an Ascendis pipeline where it is endocrinology. First, there needs to be synergy between the product and the other thing is needs to have at least €1.5 billion in sales revenue expectation. If any chance it’s not on that, it’ not something we want to take on it, because we come from system where we run P&L and not just dreams. So, therefore we are building our pipeline on synergy.
So when you think about synergy then the logical word is infrastructure. And people don’t actually think about infrastructure as a key element. I really believe, IT solution, facilities, people, everything like that, this is really where you have so much infrastructure and synergy. Just conference, you go to one endo conference, you have one group for three-product. This is meaning that you basically save two-thirds. And out from that perspective and Joe can comment about it how we can do where people some way think a little bit in their mind is to think about just sales force.
So just think about medical affairs, which are running on different part of the organization. How much do you really have synergy and obvious that synergy we can switch between from one to the other. But perhaps, Joe you can say, how we have prepared. We are in the full launch mode. We have been in the full launch mode for six to 12 months now and we want to be ready for Q2 next year. It’s going to be our biggest product ever on TransCon PTH.
Li Watsek
Okay, great. Maybe just a — go ahead.
Tim Lee
Go ahead, Li.
Li Watsek
Maybe just a quick follow-up on Transcon CNP Phase 2b. I wonder if you can share some of the secondary endpoints that you talk about. My understanding is that your Phase 2 trial is still blinded. So I guess, what insight can you gain from the Phase 2 trial to help you finalize the Phase 2b protocol?
Joe Kelly
The Phase 2b protocol is already filed by FDA, so we are full-blown into our Phase 2b. We expect to enroll all the patients basically aligned now in our ACHieve trial on national history. The — just waiting to be switched over in the beginning of next year in the trial. What we have in our protocol is pretty simple that we have a huge menu list, a huge menu list of all different element where we believe the benefit could be. But I think Birgitte is in the call and she is heading up the Clinical Development Regulatory and Medical Affairs of our Rare Disease Endocrinology. Perhaps Birgitte, you will say some words about all the exploratory endpoint we have built into the protocol and we hope we can evaluate them up to secondary endpoint when we really have looked at all the data for ACcomplisH.
Birgitte Volck
Yes. Thank you so much, Joe and thanks for the questions. Yes. So I think we are very excited about the 2b protocol. And again, our objective is to hopefully provide timely access to this potential treatment opportunity. So patient relevant outcome measures is something we haven’t included current exploratory measures. That was something we were very proud of having each test developed for our PTAs program and we aim to have similar relevant outcome measures for this program.
And then we would also have other anti-inflammatory measures including [Technical Difficulty] body mass index, et cetera. So the relevant menu of relevant endpoints are captured as exploratory and will be addressed appropriately as bring insights into evidence evolved in this relatively new field of medical intervention in that contemplate.
Joe Kelly
Thanks, Birgitte.
Operator
Thank you. Our next question comes from Paul Choi with Goldman Sachs. Paul, your line is open.
Paul Choi
Hi. Thank you. Good afternoon. And let me add my congratulations on all the progress. Just a point of clarification. Can you comment on whether — clarify whether you have seen anything from the blinded portion of the Phase 2 that has informed your decision with regard to trial design for the Phase 2b APPROACH study or was it just based solely on the available open label extension data?
Jan Mikkelsen
We — as has been commented before we have looked on the blinded data for the ACcomplisH trial and we also have been looking on the open-label extension data. We believe we can do that without jeopardizing anything to the double-blinded nature on the trials. We’re feeling confident this is a responsible way to do it. And when we look on the data, we’re just looking very much forward to really disclose it to you in the coming weeks.
Paul Choi
Okay. Thank you for that. And then as a follow-up on the commercial, maybe for Joe. Can you maybe just provide us an update on what your payer conversations or feedback has been like with regard to potential pricing of TransCon PTH? You obviously launched SKYTROFA at a premium to the market average in the growth hormone category. So just maybe any qualitative or quantitative feedback you can provide would be great. Thank you for taking our questions.
Jan Mikkelsen
I think I can just start that we are in a position that we basically are evaluating exactly the optimal price structure, so we can really follow the value we have in Ascendis Patient First. And we came out with cut forward on a premium pricing. And I think we did it well really respecting the value of what the product is providing not only for the patient the caregivers but also for the society. And we believe we will do the same responsible thing when we come to TransCon PTH. Joe, will you comment on the more factual part on it or…?
Joe Kelly
Yes. Sure. Paul, so right now MMIT says that we have around 60% coverage at this point. But really what we’ve seen so far since the launch is that’s really not important. Because we are — HCPs are getting patients reimbursed whether they are covered or not. If they are willing, which most are, to put in the work to get that patient reimbursed, typically they’re getting a thumbs up from the PBM and the payer.
Jan Mikkelsen
I think, it was coming a little bit about our TransCon Growth Hormone SKYTROFA sales. But I think, Paul, wanted to more hear about the PTH pricing structure.
Joe Kelly
Okay.
Jan Mikkelsen
Yes.
Paul Choi
Yes.
Jan Mikkelsen
If you have any thoughts?
Joe Kelly
Yes. I mean, there are synergies. When we’re out in the marketplace in front of the payers and PBMs that will certainly leverage between SKYTROFA and TransCon PTH once approved. And that’s all I’ll comment about that, Paul.
Paul Choi
Great. Thank you.

Thank you. Our next question comes from Vikram Purohit with Morgan Stanley. Vikram, your line is now open.
Vikram Purohit
Hi. Good afternoon. Thanks for taking our question. So first one on SKYTROFA. So we all know that, obviously, you provided a threshold for revenues for SKYTROFA that you could achieve for 2022 last quarter. But, I guess, looking forward, do you plan to provide formal yearly SKYTROFA sales guidance in 2023?
Jan Mikkelsen
No.
Vikram Purohit
Okay. Understood. So follow-up question then, separate topic. IL-2 beta/gamma data expected by the end of the year, what could we expect to learn there? And then, do you think that would be enough of a dataset to make decisions on next steps for that program?
Jan Mikkelsen
First of all, when I look on our IL-2 beta/gamma, we have a dream not to make something that can combine with a checkpoint inhibitor, but — and treatment we’re seeing available for the patients that’s basic, providing better efficacy better safety than what you can achieve with checkpoint inhibitors. And our program is progressing on a speed and with data that really is supporting the speed.
I’m really pleased to see it, because the TransCon technology, together with our protein design of an optimal high potent non-alpha compound is an optimal combination to achieve this. And what Stina and her teams are really executing on and I’m really happy that we not have a recommended Phase 2 dose yet, because we are still dose escalating to complete the time what we expected to do, because the profile is so extremely safe. So, Stina, your comments?
Stina Singel
Thank you, Jan. We are in the middle of monotherapy dose-escalation and also dose escalate in combination with a checkpoint inhibitor. By the end of this year, we hope to have some initial first results for you on the clinical data.
Most impressively, I think, as Jan has mentioned is that, the safety is as we have designed with the TransCon technology to do, which is to make cytokine therapy very tolerable for patients. And I think the key thing we are looking for is the pharmacodynamic effects, how far we can push it beyond what we have seen with any other IL-2 variants out there.
Jan Mikkelsen
So, how we — typically, just to mention to give you a little bit more concrete flavor on, we look at ALC, we have a target we need to be plus five in ALC and no one else have ever meant to do that. Why do we believe that? Because if you look on product, if you really have a patient that can tolerate the treatment, they are about two to three-fold in ALC. And then you start to see monotherapy effect.
So all the companies that are developing a non-alpha and have in ALC under two or three, there is no expectation ever for them to see monotherapy effect, because by biology the science is not really supporting it. This is why we want to go up as fast as possible to an ALC that’s higher than anyone else had do, because then we know that the hematological system is really prime to fight and kill the cancer.

Thank you. Our next question comes from Leland Gershell with Oppenheimer.
Leland Gershell
Hey, guys. Thanks.
Jan Mikkelsen
Good morning, Leland.
Leland Gershell
Hey, good afternoon. Thanks for taking my questions and good to see the progress. Just a question — two questions from me. One on TransCon CNP, just again drilling down further on the regulatory side. The other company that’s out there with its own achondroplasia product now has said that, the accelerated approval pathway would be close to any new entrants given their approval.
So should we take that to mean that you would need the Phase 2b planned at least to get approval, or do you think that through discussions with FDA or other agencies you may be able to file off of the ACcomplisH data just to clarify that?
And also want to ask, with respect to SKYTROFA, in the absence of any guidance expectation for next year, could you comment if you’re comfortable with the current quarterly run rate as you’ve indicated for Q3 to Q4 of this year as we go into 2023? Thank you.
Jan Mikkelsen
Yes, let me start on the last question. Because what is the great thing with SKYTROFA sales is that, we’re building on last quarter’s baseline. So if you, for example, are saying is that this quarter here, we have €12.4 million, we basically are keeping patients on treatment for three to four years. Meaning is that, we already have €12.4 million for Q4.
So Joe and his team go out and getting new patients, new reimbursed patients, is just adding up. So if you’re, for example, saying if he do with the same speed as he did in this last quarter in Q4, he will end with €16 million to €18 million in Q4. It’s a similar calculation, even I can calculate it without an MBA.
And if you then take four times, for example, 17 in the middle and then you can say that is baseline we already have an expectation to see in 2023. So everything we add of new reimbursed patient is add on this baseline. And this is really nice calculation and a nice way to look at it. And I like mathematic algorithm a lot. And it gives me an easy way to some way make my own prediction about what I see of expected revenue for 2023.
The last question is a big, big, big, big question for me, because I really don’t understand this question. I’ve got it about 20 times now and I think it’s somewhere being generated out from a lack of knowledge, a lack of understanding of regulatory pathway in the US.
What is happening is that the primary endpoint is getting validated utilizing – analyzed at the — as the endpoint, this does mean is that it’s not close for anyone else. So I’m totally lost in this question and I don’t think there is any kind of scientific regulatory element that really someway supporting this kind of statement.
Leland Gershell
Okay. Thank you very much.
Operator
Thank you. Our next question comes from Joseph Schwartz with SVB Securities. Thank you for standing by. Joseph, your line is now open.
Joseph Schwartz
Great. Hi. I think that’s me. Congrats again. I was wondering since you alluded to updated guidelines being a meaningful driver for TransCon PTH when it’s hopefully launched, I was wondering if you can expand on that a bit and discuss how much this versus other factors might improve the reimbursement positioning, which we’ve heard was very different for [indiscernible] when it was launched. What are your current estimates for the revenue potential of TransCon PTH?
Jan Mikkelsen
It’s — what, I really, were extremely pleased. What really are giving Joe a much easier life. I’ll try to make his life pretty hard. But what’s really giving him a much easier way to get the right market access in the US is the updated guidelines, because when I read the guidelines, the guidance is basic justifying that you are taking the majority of the patient on PTH 3. And to my knowledge even I have not really with the case studies I’ve seen it’s very, very hard for US market assist system to avoid something that’s already are taken into guidelines.
So I actually feel when we discuss the sales revenue prediction of this year, I always start on one single thing the unmet medical need. The unmet medical need is really dramatical for the patients with hypopara. Not only the short-term symptoms, but also long-term complications, and the problem with conventional therapy it basically makes the disease worst. It’s basic are making the disease worse and worse, because the treatment of it choose amount of calcium supplement and activate vitamin D.
It basically is increasing all the complications base case complications and not really providing a relief for short-term symptoms. So when I look at the number of patients in the US that is available for treatment 80,000 to 100,000 in a broad perspective. I believe that majority of these patients should be on PTH treatment. Will all of them be commercial reimbursed life? I cannot guarantee that, but I think the majority should be it.
And the price structure as we said before we will be responsible. We will still — saying is that we are providing a huge benefit not only for the patient the caregiver, but also for the society. And this is why we believe in a premium pricing for best-in-class product opportunities.
Joseph Schwartz
Okay. Thank you. And then I have a question about the pen device for TransCon PTH, which I think is important but hasn’t really been discussed much. So I was wondering if you could talk about the pen and how it compares to what’s used for the SKYTROFA and maybe how does it help patients titrate to the right dose of TransCon?
Jan Mikkelsen
Yes, you’re right. We don’t talk so much about the pen device for TransCon PTH compared to SKYTROFA because for SKYTROFA, we develop a complete new pin auto-injector for this. It’s actually really boring in TransCon PTH, because we’re using a pen device that’s getting utilized million and million and million of times in the US every day because it’s a basic classical insulin pen device. And it’s pre-filled liquid formulation for room temperature are optimal for the patient. So it’s pre-filled you don’t need to prime it and then you use the pen device for two weeks 14 days and then you take a new pen.
And it’s basic is built on a low-dose, medium dose, high-dose and each pen the low-dose, medium dose and high-dose have three different strengths. So we basically are covering nine different presentation or that nine different way. So each subject, each patient can be optimized to the treatment. But Joe, why we don’t talk about it because it’s really a proven technology, a technology that is used in the insulin era millions — millions of times everyday.

Our next question comes from Andreas Argyrides at Wedbush Securities. Thank you so much for standing by. Please go ahead.
Andreas Argyrides
Thanks for taking my questions. Congrats on the progress in the quarter and SKYTROFA beat. Can you provide an update on the status of filing for children in Turner Syndrome?
Joe Kelly
We just need to do the clinical trial, first. And based on the clinical trial, we will provide you a date on that. So we will provide that when we basically, have done the clinical trial. We will provide an update when we expect to file and what is the next step.
Andreas Argyrides
Okay. And then for pediatric HP, as well?
Jan Mikkelsen
Pediatric HP is an interesting element for us because we initiate the strike. We have designed or taking the insulin pen, into a new consideration because we have a pediatric system for the pediatric population, and I believe and I’m little bit perhaps Birgitte, you can help me here because I cannot really exactly remember, what time next year we start the clinical trial.
Birgitte Volck
I don’t have the exact details to be shared now, but we are working our path forward for these studies. So, no additional details for that.
Jan Mikkelsen
Sometime next year we will start the clinical trial. It’s a very, very small clinical trial, single-arm. This is what we got all the regulatory feedback. I think it’s about between 20 to 25 patients another six months not a last trial at all.
Andreas Argyrides
Okay. Great. Thanks for the update and congrats again in the quarter.
Jan Mikkelsen
Thanks so much.

Thank you. Our final question comes from Yaron Werber with Cowen. Thank you so much for standing by. Please go ahead.
Yaron Werber
Yes. Hi, thank you. Thanks for taking my questions. Jan, maybe just an integrated question relating to — So the 5.4 centimeters per year you’re obviously referring to the two-year extension on Vaxogo in patients older than five. The placebo did about 3.8 centimeters per year, at baseline. And then when it switched over they did 5.4 obviously, on Vaxogo . Is 3.8 sort of a good comp to what to expect in the placebo? And that’s all-in the five-year-old plus. What about the two to five-year-olds? So how should we think about that when we see the data? Thank you.
Jan Mikkelsen
Yes. This is where the two to five is really not, an patient population where that’s good benchmarking at all. All the data, I have seen is filled with huge amount of the ability. And I actually hate to benchmark against anything that basically, are already built on huge amount of the ability without solid data because then you take two datasets, one dataset that is built on a limited number of patients compared and benchmarked it to and other dataset, that also built on a limited number of patients, we choose their ability.
So this is why, I separated between two to five and five and up before there’s a really solid data-set in the patient population from five and up. For example, the publications that you’re referring to. And this is why I don’t believe it’s meaningful really to do a lot of comparison, from the two to five because of the lack of real benchmarking.
