Thank you, operator. Good morning, everyone, and welcome to United Therapeutics second quarter earnings call. I am Roger Jeffs, President and Co-CEO. I am pleased to be joined on the call today by James Edgemond, our Chief Financial Officer; Dr.

David Zaccardelli, our Chief Operating Officer and EVP, Product Development; and Andy Fisher, Deputy General Counsel and Chief Strategy Officer. James, David and Andy will assist me with answering questions related to their respective area of expertise in finance, development and legal, respectively.

No doubt, many of you are now wondering, where is Martine? Well, Martine sends along her regrets for not being able to participate today, but she is away on an international business trip and not able to join today’s call. So I’d like to take the opening time period to provide a summary across three main areas.

Firstly, I’ll review our quarterly financial results; secondly, I’ll provide specific detail with regard to Orenitram performance; and thirdly, I’ll highlight other material achievements during the quarter.

Starting with the financials, we continued to see year-over-year, as well as quarter-over-quarter total revenue growth with the increase driven primarily by Orenitram sales growing nearly 300% as compared to the second quarter of 2014, when the product was first launched, and Orenitram growth of 24% when compared to Q1 of this year.

This growth in Orenitram is principally result of increased patient demand, and I’d like to specifically unpack the Orenitram number in more detail in a minute given the keen interest in the performance of this brand.

In addition, second quarter revenues also benefited from the growth of Adcirca sales, which grew 23% as compared to the second quarter of 2014. Much of this growth is related to price increases. Remodulin and Tyvaso revenue were sustained year-over-year.

As we have previously mentioned, it’s best to view our revenue trends over the longer term as it better reflects our overall growth and takes up some of the revenue volatility resulting from monthly ordering patterns of our domestic and international distributors.

This longer lens provides a better viewpoint of the impact of the launch of Orenitram across the suite of treprostinil products. We reported GAAP net income was $99.2 million or $1.91 per diluted share for the quarter ended June 30, 2015, as compared to $111.9 million or $2.10 per diluted share in the second quarter of 2014.

Non-GAAP earnings for the quarter ended June 30 improved 12% to $132.5 million or $2.55 per diluted share, as compared to $118.7 million or $2.23 per diluted share in the second quarter of 2014, primarily driven by an increase in total product sales and the expiration of our royalty obligation to GlaxoSmithKline in October of 2014.

As mentioned in prior calls, we report non-GAAP earnings to take out the impact of certain items, including our share-based compensation. A significant non-GAAP earnings adjustment is for the share-based compensation expense. Within the quarter, we recognized approximately $47 million of employee share-based compensation expense.

As Martine outlined in the Q1 conference call, we have a share tracking awards program, which are essentially stocks settled in cash - stock options settled in cash and when these awards are mark-to-market, it is reporting period and the increase or decrease in our share price introduces volatility into our reported GAAP earnings.

The additional share tracking award expense recognized during this quarter is attributable to the additional vesting of STAP awards, the actual additional gain that employees recognize upon exercise of the STAP awards at prices above the prior quarter and share price, and finally the increase in the share price.

Turning to the balance sheet and statement of cash flow, which in the 10-Q represented on the six month basis, cash and cash equivalents and marketable securities as of June 30, 2015, and December 31, 2014 were $552 million and $818 million, respectively.

The decrease of $256 million in cash, cash equivalents and marketable securities resulted primarily from both the use of $337 million to repurchase shares of our common stock and the use of $104 million to settle early convergence of our convertible notes. These uses were offset by $150 million of cash generated from operating activities.

I also want to take a brief moment to update you on our share repurchase activity during the quarter. As mentioned, we spent $337 million to repurchase shares of our common stocks since year-end, and about $185 million of this amount occurred in the second quarter of 2015 when we repurchased over a million shares of our common stock.

By the end of July, we expect to fully complete the 500 million share repurchase program that was authorized by our board late last year in August of 2014. As promised, now I’ll switch gears and spend a little time unpacking the Orenitram numbers in more detail.

I think the granularity will provide great insight and enthusiasm that the brand is achieving its goals. As already mentioned, Orenitram continues to grow with Q2 being our strongest revenue quarter yet, having achieved 24% greater revenue than in Q1.

Orenitram revenues were driven principally by new patient starts with the number of patient starts exceeding 1,000 patients since launch, just thus achieving our patient target for year one. A mirror into future revenues can be predicted by the number of patient referrals.

Q2 referrals were 21% higher than Q1, which obviously bodes well for Orenitram performance in Q3. In fact, June was our highest referral month ever, which gives us confidence that Q3 will come in north of $30 million if the July revenue number remains consistent for August and September.

The growth in new patient starts is driven principally by the increase in the breadth of prescribers. Since launch, over 400 prescribers have started a patient on Orenitram. In fact, we were averaging 24 new prescribers per month. Today, 70% of the starts in Q2 were from patients new to prostacyclin, with 30% being transitions from Tyvaso or Remodulin.

And while this has kept the growth of Remodulin and Tyvaso relatively flat, it is important to note that the total number of patients on any form of treprostinil continues to grow, which again achieves our stated objective of treating more and more patients with one of our available forms of treprostinil.

Importantly, we are seeing a nice uptake in the community centers where we feel is the largest opportunity for growth, given the low utilization of prostacyclin therapy in the community setting. In fact, recent trends show a higher percentage of utilization of Orenitram in the community centers.

For example, the split of starts in June was 55% community-based and 45% center-based, which demonstrates the positive inroads we're making with Orenitram with the community physicians.

While patient number is certainly the key driver of revenue in this initial phase of launch, another important driver of Orenitram performance is related to dose achieved as of cost and thus the revenue is based on milligrams used. Like parental therapies, Orenitram is progressively titratable to achieve a balance of maximum benefit and tolerability.

A hallmark of prostacyclin therapy and a key class trait. The average total daily dose for all patients is currently 10.2 milligrams. The average dose is obviously impacted downward by new starts that begin at the lower end of the dose spectrum.

We now have enough patient sample across the first year to provide insight into longitudinal trends of dose versus time on therapy. The average total daily dose across all patients approximately 8 milligrams at three months, 10 milligrams at five months and 12 milligrams at 10 months.

This suggests that dose titration is most aggressive in the early titration phase, and then continues at a slower pace as the balance of benefit to risk is achieved but nonetheless titration is, as expected, it continues as expected and has been shown historically is required for this class of therapy.

Progressive dosing for progressive disease so to speak. There will obviously be a greater and greater impact of dose on revenues, as patients increase their duration on therapy, further leveraging the increasing patients on therapy impact. Finally I'd like to provide a few brief highlights of a few other important achievements in the quarter.

Most importantly, we launched Unituxin, and in fact, we fulfilled initial distribution orders and treated our first patients. We are very excited about being able to serve this community of children who need treatment for high-risk neuroblastoma.

In addition in May, the EMA’s Committee for Medicinal Products for Human Use issued a positive opinion recommending approval of our marketing authorization application for Unituxin.

We expect to receive European Commission approval during the early part of the third quarter of 2015, and thereafter plan to commence commercial sales in individual European countries, following pricing and reimbursement approvals on a country-by-country basis.

We continue to favorably progress enrolment in our large pivotal Phase III morbidity/mortality endpoint trails with FREEDOM-EV approaching 60% enrollment and the BEAT study approaching 50% enrollment. With those opening remarks, I'd now like to open the lines up to callers for questions for myself James, Dave or Andy. Operator, first caller please..

Great. Thanks for taking the question, and thanks a lot, Roger, for such a great detail on Orenitram. I wanted to go a little bit more on that vein.

Could you give us a perspective on duration of therapy, how do you see persistent rates playing out over the next, say what’s happened historically and over the next say six to 12 months, and then what does your market research tell you about the meds that patients have had before on Orenitram just to get a sense for where we are in the sequencing of therapy? Thanks a lot..

Yes, good morning, Geoff. Thanks for the question. So in terms of more detail, it's a very hard to give a duration in persistence because obviously we've only launched last June, so the persistence at best would be 12 months for the first patient in, commercially.

So we do have a little inside however from our open-label controlled clinical study where patients exited the control portion and went into the open-label portion. And there we saw that the patients had a persistence well over two years. Early suggestions are is that this is tracking very similarly to Tyvaso in terms of tolerability and persistence.

So we do lose some of the starts, some of the patients die unfortunately. There is some intolerance mostly due to headache, nausea and GI distress, which is typical of prostacyclins but the large majority of patients stay on therapy and continue.

The advantage of that, as you’ve heard in the opening comments, is that as they stay on therapy, the dose escalates with time, as they continue to titrate the drug to maximal benefit and tolerability.

One of the questions we have for ourself is sort of where is dose heading? So if it's 12 milligrams as a total daily dose at 10 months, where will it end up? And one potential window into that aspect is, if you look at those patients that were in the open-label clinical trial, who have now transferred to commercial products.

So there is a subset of our commercial patients, but they are the patients that have been on the therapy longest. Their average dose is about 20 milligrams. It's a total daily dose.

So it's our expectation that, of all the patients that we had, if they stay on therapy for a longer period of time, they will also begin to approximate that level of dosing which will then obviously port a higher level of revenues per patient.

So that's the leverage aspect that I mentioned in the opening, that it’s not just the numbers of patients but it's the dose that will drive the upside. So hopefully that answers your question about duration and persistence. In terms of market research or market feedback, we do find a couple of things.

We find that about 70% of the patients are on three times a day dosing versus twice a day. That seems to be the preferred route.

In terms of use on top of background therapies, we don't promote it that way, which is promoted as a frontline use, the prostacyclin are first choice so to speak, but lot of patients are on background therapy and that doesn't seem to be a hindrance at all in terms of this prescription behavior or payor behavior.

So I think a lot of uses is follow-on therapy to other oral therapies. So does that….

Great, thanks..

Thank you, Geoff. Next caller, please..

Thank you. Our next question comes from the line of Mark Schoenebaum with Evercore ISI. Your line is now open..

Hi, Roger, and hi guys, this is Salim in Mark. Thanks so much again for the color. Roger, it was super helpful. Just one critical question and then two quick ones, if I may. On the patient numbers, I know last quarter you mentioned there were 800 patients. This quarter you mentioned there is a 1,000, and last quarter you said there was 100 net new adds.

So is that slowing down? And then the high-dose patients, you mentioned last quarter I believe that 20 per month were rolling off. So can you just give us more clarity if that’s still occurring and how many high-dose patients remain and where are they going? And then the two quick ones.

On the share repo, would you guys be willing to consider a Dutch tender and be more aggressive in the share buyback? And then on Unituxin, do you expect any competition there from products and development? Thank you..

Okay. All right, so we’ll ask for just one question per caller after this. So in terms of the patient on therapy. So the starts since launch have been well over 1,000. If you looked at the number of patients on and pending, then we have about 1,000 patients in our census. So that's the answer to that.

In terms of dropout, patients dropout across all spectrums of dozing and all spectrums of time and there can be - death can occur. That's one of the largest reasons for discontinuation of any treprostinil therapy or they dropout due to intolerance.

Now intolerance would typically happen early, so that gets filtered out very quickly and has less impact obviously then on revenues going forward because they are not on therapy and on higher doses. But the patients that discontinue, who have been on at a higher dose have a greater impact on the revenue number.

I'll touch on Unituxin, and then I’ll prompt to James on the share repurchase question. So on Unituxin, there is a company in Europe that is developing basically 14.18 like very similar product. It’s manufactured differently. It’s a CHO cell-based manufacturing production. It has different glycosylation features.

They are developing it with a different cytokine adjunctive therapy regimen. We think that the regimen that was developed by MCI and COG [ph] was the right regimen and certainly that was born out in the clinical trials, where you saw both, event-free survival significantly improved as well as overall survival.

We don’t view the other product as competitive, because they have an unblinded their study, so we don’t know if their regimen will work. It’s a similar product, but we do have orphan designation.

So in Europe, I think that has potential to negate their ability to commercialize, although it's - again it's not something I don't think will defend aggressively in Europe.

The only issue we’ll have in Europe as we begin to commercialize ourselves is that that therapy has been tested in a lot of the main centers and it may infringe on some of our commercial uptake because they are going to be using new clinical trial material from that trial.

But other than that, I think our stated expectation that the global revenue expectation for Unituxin is between $75 million and $100 million remains true and hope the same.

So, James, if you could answer the question on share repurchase?.

Yes. Thanks Roger. Good morning, Salim. As you know, Salim, historically we’ve repurchased shares and we've done the accelerated share repurchase, and we've also done it through open market. So we have been committed to share repurchase. I don't want to say whether we would or wouldn't consider going forward other mediums or other vehicles.

I think the thing to keep in mind for us is we have the open share repurchase program right now, and we’re committed to completing that by the end of the month. So thank you very much..

Thanks so much..

Thank you. Our next question comes from the line of Liana Moussatos with Wedbush Securities. Your line is now open..

Thank you for taking my question. Can you talk about the earlier stage pipeline implantable pump and behind that and what kind of catalysts we can expect between now and year-end and 2016? Thank you..

Yes. Thanks for the question, Liana. And I'm very pleased to introduce Dr. David Zaccardelli to this earnings call. Dave was promoted to Chief Operating Officer in January. Dave has been with United Therapeutics almost 10 years and has been pivotal to our success. And so Dave, if you would answer that pipeline question, I’d appreciate it..

Thank you, Roger, and thanks very much for the question. I'm happy to comment on the implantable pump program and also our other pump program with DEKA. As you may know, we have a collaboration that's been in place with Medtronic to progress their SynchroMed II pump into the marketplace for use with treprostinil pulmonary hypertension.

That has progressed substantially to the point where a PMA was submitted by Medtronic. An NDA also was submitted by UT in order to support that. We have subsequently received refusal of file on the NDA and have been in communication with the Agency, as well as Medtronic has received some comments on their PMA.

Both of those have to progress at the same time in order to complete that, and we’re working with the Agency and Medtronic to sort that out. And hopefully in 2015, we’ll be able to provide the Agency the information they request and then look forward to hopefully progressing that to an approval sometime in 2016, is our current plan.

But as you know, that program is substantially been with Medtronic and so we rely on them for the responses and for their collaboration. But we’re working very closely with them and very closely with the Agency to get that done.

I'm also pleased to say that we have a collaboration with DEKA Research in order to progress a proprietary based small pump platform for subcutaneous administration, and the teams are working very closely together now to work with putting treprostinil in that pump platform and we're working at making the submission which would be a combination drug device submission to the Agency sometime in early 2017 and look for an approval of that later 2017 or early 2018.

And so both of those, our pump platform play for progressing treprostinil with a easier to use pump platform..

Great. Thank you for the very good answer, Dave. Operator, we’ll take another caller, please..

Thank you. Our next question comes from the line of Phil Nadeau with Cowen and Company. Your line is now open..

Good morning. Thanks for taking my question. Roger, a follow-up on your Orenitram comments. Just doing the math here. If we assume 900 patients on therapy on average for the quarter times 90 days in the quarter at 10.2 milligrams and $39 per milligram, we get to $32 million of revenue. Obviously you reported $25 million.

So that implies maybe 22% gross to net adjustment. Is my closed-in [ph] assumption accurate, or is my math in some other way flaw that it’s meant again to account some other element that we should be considering? Thanks..

Yes, so it’s not as simple as doing the math the way you’re doing it. So the purchases by the specialty pharmacies are based on a past months census and a knowledge of what the referral rate is. So they order towards a future inventory level to meet a minimum requirement.

It doesn’t - so the math doesn’t always work out as nicely and cleanly as you articulated. I think your math does accurately predict where we’re headed, but it doesn’t say why we have - the revenue isn't what you just described it to be within the current quarter, and obviously we also start patients within the quarter.

So if we don’t - there is different levels of inventory required for those patients as well. So it’s really a flux based on past active census and referrals and an expectation also with discontinuation. So they do that calculus. They have a formula and then we ought that they maintain minimum inventory levels. So it’s more done that way..

So when we try to predict revenue, what is the true patient number that the specialty pharmacies will be looking at? Is it like a couple month lag or….

Yes.

So it’s - in general, I think it’s a 30 to 60 day lag is what happens, which as I noted in the opening with referrals being robust in Q2, that bodes very well for Q3, which is why we’re confident in predicting where revenues will head in the next quarter if things hold true, which we expect they will, in fact we should add - continue to add patients and we could improve upon that.

So you’re right, the lag is 30 to 60 days in general. And that’s why there is lumpiness in the numbers.

That’s why it’s better to look - when you look at a quarter-to-quarter, it’s always better to look at our businesses year-over-year is a more predictable way to look at treprostinil revenues than quarter-over-quarter, particularly in such an early phase of launch which Orenitram is still in. Thank you. So operator we’ll take another caller, please..

Thank you. Our next question comes from the line of Michael Yee with RBC Capital Markets. Your line is now open..

Hi, it’s Mike Yee from RBC. I wanted to ask a bigger picture question for you. Obviously you’ve done a ton of great things with treprostinil.

Just want to understand given your balance sheet, your flush with cash for profitable, how you’re looking at thinking about bringing in maybe new things, in-licensing things, commercial, things that could leverage your commercial infrastructure and all the things you’ve done already in the past.

So we haven't really heard of that with you and maybe thinking about the opportunities for you to bring stuff in. Are you thinking about that, or you’re not thinking about that, or you’re in early stage pipeline stuff. How should we think about building out beyond treprostinil? Thanks..

Yes. Thank you for the question, Michael. So it’s one that’s at the forefront of our mind. We’ve recently hired Director of Business Development because we’re trying to be much more active in our strategic acquisition investigation.

So our development efforts are really focused on areas where we can leverage our infrastructure and expertise and rapidly develop and commercialize high impact medications.

Our emphasis in terms of where we’re looking to answer your question is on orphan indications that are poorly addressed by current therapies, particularly in the pulmonary and oncology therapeutic areas where you have strong platforms in place.

We’ve been engaged in active discussions with companies ranging from start-ups to top 10 drug companies looking to either acquire or in-license assets.

It’s a pretty robust time in oncology, but we think particularly in pediatric oncology we can be a major player and there is ways to leverage not only Unituxin but our presence in that space and our ability to serve that community to help out some of the other successful compounds that are being developed for adults and partner with companies to do that as a specific priority objective.

It reminds me sort of the blank white space that pulmonary hypertension was when we first started United Therapeutics. There was very little interest in pulmonary hypertension and since that time obviously this indication has exploded. We think pediatric oncology has potential to be a similar growth opportunity.

In pulmonary conditions, particularly pulmonary hypertension, I think we’re the go-to company. If somebody has something for pulmonary hypertension, they usually call us. So there is a lot of inbound activity to us for new targets for pulmonary hypertension.

Our emphasis there though is we want something that’s interesting in the sense that it should be disease modifying. We don’t want another add-on nasal dilator [ph] type therapy. There is enough of those so to speak. So for us to get engaged in something in as a small molecule or a biologic therapeutic, it would have to be disease modifying.

And we started that a few years ago when we did our collaboration with Pluristem with a PLX or the mesenchymal stem cell-like therapy which is in Phase I in Australia, but we’re engaged in other interesting opportunities there.

Having said that, if it’s an orphan and unmet need and there is a potential for a high impact medication and the science is supportive, we’ll look outside of pulmonary hypertension, and we’ll look outside of oncology if it makes sense to do so.

Most of what we’re looking at though is in the preclinical or early development stage, and we haven't - we’re not looking at - currently at more of a products acquisition opportunity. So that’s kind of in a nutshell what we’re trying to do with our business development platform. We’re very active.

We’ve probably had 30 active products just within the past six months. About a third of those we’ve taken to a higher level of due diligence, and again many of those remain active. So we are looking to enhance and build our portfolio of products.

Having said that, we have a lot of pipeline opportunity with our follow-on study with Orenitram, the FREEDOM-EV. We think to port the full value of Orenitram, we need to complete successfully the FREEDOM-EV study, and as Dave mentioned, that’s well on track to about 60% enrolled and it’s moving towards completion in late ‘16 and unblinding in ‘17.

BEAT is also another shot on goal for a morbidity/mortality endpoint study with a new therapeutic option for patients with an oral prostacyclin.

So that’s a rich Phase III pipeline there, but we would like to build out some earlier stage pipeline opportunities which could then grow into later term revenue opportunities and that would sort of supplement revenue streams prior to our xenotransplantation and reaching our medicine opportunities coming to fruition..

So operator, I think that’s it for calls. And we appreciate everybody calling in today and joining us for the second quarter earnings call, and we look forward to speaking to you at the next earnings call. Thank you very much..
