My name is Skinner, and I'll be your conference facilitator today for Amgen's Second Quarter 2017 Financial Results Conference Call.
(Operator Instructions)
I would now like to introduce Arvind Sood, Vice President of Investor Relations.
Mr. Sood, you may now begin.
Arvind Sood - VP of IR
Thank you, Skinner.
Good afternoon, everybody.
Thanks for taking the time to participate in our conference call today to review our results for the second quarter.
So before we begin, I would like to acknowledge those who are new in their coverage or have changed jobs recently, including Michael Yee, who is now Jefferies; Andrew Peters of Deutsche Bank; and Matt Phipps of William Blair.
Each of us look forward to working with you.
Okay, so let's go ahead and get started with the business at hand.
Consistent with the theme that we discussed at the beginning of the year, we delivered a quarter with strong volume growth -- volume-driven growth of our newer products, which, of course, will be key for our long-term growth strategy.
So leading our call today is our Chairman and CEO, Bob Bradway, who will provide a brief strategic update.
Followed by our CFO, David Meline, who will review our financial results for the second quarter and our outlook for the remainder of 2017.
Our Head of Global Commercial Operations, Tony Hooper, will then discuss our product performance during the quarter.
Followed by our Head of R&D, Sean Harper, who will provide a pipeline update.
We will be using slides for our presentation today, which have been posted on our website and a link was sent to you separately by e-mail.
We plan on using non-GAAP financial measures in today's presentation to provide information which may be useful in understanding our ongoing business performance.
However, these non-GAAP financial measures should be considered together with GAAP results, and reconciliations of these measures are available in the schedules accompanying today's press release, our Form 8-K and also on the Investor Relations section of our website.
So just a reminder that some of the statements made during the course of our presentation today are forward-looking statements, and our 2017 10-K and subsequent filings identify factors that could cause our actual results to differ materially.
So with that, I would like to turn the call over to Bob.
Robert A. Bradway - Chairman and CEO
Okay.
Thank you, Arvind, and let me thank all of you for joining our call.
Halfway through the year, we remain on track to achieve our objectives for 2017 as well as our longer-term objectives.
Our second quarter financial performance was enabled by strong volume-driven growth for our newer products including: Prolia, KYPROLIS and Repatha, as well as our other more recently launched drugs.
This is encouraging as we continue to believe that such volume-driven growth is a key ingredient for long-term success in this industry.
Our transformation efforts are enabling us to make significant investments in our pipeline and new product launches, while still delivering near-term operating leverage, and you see that reflected in our 9% operating income growth and our 15% earnings per share growth this quarter.
Our margin trends also reflect the success of our ongoing transformation.
We continue to generate strong cash flows, enabling us to return significant cash to shareholders, including almost $2 billion in the second quarter alone in share repurchases and dividends.
Strong cash flows combined with a strong balance sheet give us the strategic flexibility we want to invest in external innovation.
We're continually looking at opportunities in our chosen therapeutic categories, yet we remain disciplined in our approach to looking for investments that will enable our shareholders to prosper.
Turning to our product highlights.
I want to start with our cardiovascular business and Repatha, which we expect to be a significant contributor to our long-term volume-driven growth.
Our focus right now is on improving Repatha patient access in the U.S. and around the world.
And with our outcomes data in hand, we're making progress.
I was pleased to see the swift updates to cholesterol treatment guidelines and recommendations from 4 leading professional societies interested in atherosclerosis and expect more to come.
This change in professional opinion is an important precursor for growth in the market.
Additionally, our recent discussions with U.S. payers about Repatha and the need to improve the utilization management process has been constructive, again, reflecting the strengths of our data.
Finally, we submitted our outcomes data to regulators this quarter and look forward to being able to incorporate them into our label following regulatory review.
Within oncology, I want to highlight a few recent notable milestones.
First, in multiple myeloma, we completed 2 pivotal studies showing an overall survival benefit for KYPROLIS patients with relapsed disease, underscoring our confidence in this molecule as the new standard of care for these patients.
And similarly, in relapsed and refractory acute lymphoblastic leukemia, BLINCYTO demonstrated an overall survival benefit versus standard of care chemotherapy.
I would remind you that BLINCYTO is the first and only bispecific T-cell engager to have done that.
Overall survival is the gold standard when it comes to oncology drug development, and we were encouraged to be able to show that patients live longer when treated with KYPROLIS and BLINCYTO.
In neuroscience, we're getting closer to being able to make a meaningful impact in the lives of migraine patients.
We submitted erenumab, for which we have the brand name, Aimovig, to U.S. regulators in the second quarter.
We have the lead position in this exciting new class of medicines, combining our commercial strengths in specialty biologics with Novartis' established infrastructure in neuroscience, we think, positions us to win in this segment.
Our biosimilars programs continue to advance nicely and the quality of our work here was on display once again in the recent FDA panel review of our biosimilar to Avastin.
The outlook for the company remains strong with growth from newer products and effective life-cycle management of our legacy products, we're confident in our position and looking forward to the second half of the year.
Let me now turn to David to review the financial performance of business.
David W. Meline - CFO and EVP
Okay.
Thanks, Bob.
We're very pleased with our consistent revenue and earnings growth in the second quarter as our transformation efforts continue to enable investment in our core business, while also delivering operating leverage in the period of portfolio transition and the competitive environment.
Turning to the financial results on Page 6 of the slide deck.
Worldwide revenues at $5.8 billion in the second quarter grew 2% year-over-year.
This quarter, we also saw our products sales at $5.6 billion, growing 2% year-over-year as well, as strong unit growth demand for our newer products outweighed declines in the mature brands.
We're particularly encouraged by our 11% year-over-year volume growth in Europe, reflecting the value of our innovative products in a market where we have experienced biosimilar competition and portfolio transition for a number of years.
Other revenues at $236 million grew 10% versus the second quarter of 2016, driven by higher Ibrance royalty revenue, offset partially by decreased Nexavar royalty revenue.
Changes in foreign exchange had a 1% negative impact to total revenue and product sales in the quarter on a year-over-year basis.
Non-GAAP operating income at $3.1 billion grew 9% from the prior year.
Non-GAAP operating margin improved 3.8 points to 55.2% for the quarter, reflecting positive revenue performance, continued favorable expense impacts from our transformation initiatives across all operating expense categories and the expiry of the Enbrel residual royalty payment in Q4 of 2016.
On a full year basis, we expect another year of strong operating margins, driven by tight operational expense management.
We expect to see our typical trend of higher operating expenses during the second half of the year.
On a non-GAAP basis, cost of sales as a percent of product sales improved by 0.8 points to 12.7%, driven by reduced royalties.
Research and development expenses at $851 million were down 3% year-over-year, driven by lower spending required to support certain later-stage clinical programs and continued benefits from our transformation initiatives and process improvement efforts.
R&D as a percent of sales was 15.3% in the second quarter.
We expect research and development as a percent of product sales to approach 2016 levels in the second half of the year.
SG&A expenses decreased 7% on a year-over-year basis, due to the expiry of the Enbrel residual royalty payment, partially offset by increased investments in product launches.
In aggregate, non-GAAP operating expenses decreased 5% year-over-year and remain on track to meet or exceed our 2018 commitment of $1.5 billion in transformation savings while investing to build the business globally, support new product launches and investing in the long-term pipeline for the business.
Other income and expenses were a net $156 million expense in Q2.
This is favorable by $20 million on a year-over-year basis, primarily driven by higher cash balances.
The non-GAAP tax rate was 17.4% for the quarter, a 1.2 point decrease versus the second quarter of 2016.
This decrease reflects discrete benefits associated with the settlement of certain state and federal tax matters and favorable changes in the geographic mix of earnings, offset partially by a prior year benefit associated with tax incentives.
Non-GAAP net income increased 12% and non-GAAP earnings per share increased 15% year-over-year for the second quarter to $3.27 per share.
Turning next to cash flow and the balance sheet on Page 7. Free cash flow was $2.1 billion for the quarter compared to free cash flow of $2.5 billion in the second quarter of 2016, driven by timing impacts of income tax payments to the IRS.
We continue to provide significant cash returns to shareholders, consistent with our commitments as we deployed $1 billion to repurchase 6.2 million shares at an average of $162 per share, and are on track to achieve total share repurchase for this year in the range of $2.5 billion to $3.5 billion, as previously communicated.
Additionally, our second quarter dividend of $1.15 per share is an increase of 15% over last year.
This reflects our balanced approach to capital allocation.
With significant investment in innovation in support of long-term growth of the business as well as return of cash to shareholders.
We continue to maintain financial and strategic flexibility as a result of our strengthening balance sheet position.
Cash and investments totaled $39.2 billion, an increase of $4.2 billion from the second quarter of last year.
This increase reflects continued solid net cash flow generation.
Our debt balance stands at $35.1 billion as of June 30, carrying a weighted average interest rate of 3.7% and an average maturity of 13 years.
Turning to the outlook for the business for 2017 on Page 8. Overall, our revised 2017 revenue guidance is $22.5 billion to $23 billion.
Our first half 2017 volume and price performance was in line with our plans as we experienced a solid contribution from our newer products while managing the impact of competition against the balance of the portfolio.
This range also reflects the potential impact during the remainder of 2017 from the outcome of Repatha litigation, and potential for improved access for appropriate patients as a result of the positive Repatha outcomes data and professional society guidelines and recommendation updates.
Our guidance assumes no new U.S. biosimilar competition in 2017.
With regard to our non-GAAP earnings per share guidance, we are raising and narrowing the outlook to $12.15 to $12.65 per share, reflecting our overall solid first half 2017 performance and continued operational expense management.
Further, we are confirming our non-GAAP tax guidance at 18.5% to 19.5%.
We continue to expect capital expenditures of approximately $700 million this year.
Finally, consistent with our 2017 outlook, we remain confident that we will meet or exceed the commitments we provided for the 2014 to '18 period, including double-digit non-GAAP EPS growth, non-GAAP operating margin improvement from 38% to 52% to 54%, $1.5 billion of transformation savings; and return to shareholders of at least 60% of non-GAAP net income on average during the period.
This concludes the financial update.
I now turn the call over to Tony.
Anthony C. Hooper - EVP of Global Commercial Operations
Thank you, David.
And you'll find the sales detail starting on Slide #10.
We delivered a strong solid quarter with sales increasing 2% year-over-year.
Prolia, and our more recently launched brands including Repatha and KYPROLIS, continue to deliver strong volume growth.
We are focused on a near-term growth and realizing their long-term potential as the product portfolio continues to transition.
For the quarter, sales in the U.S. increased 2% year-over-year, while sales outside the U.S. increased 8%, excluding the impact of foreign exchange, or 3% including.
Internationally, we had double-digit volume growth, led by our European business.
Let me begin first with Prolia.
Prolia sales increased 15%, with an 18% volume growth year-over-year, from share gains and in both the U.S. and our international markets.
Prolia continues to offer a unique opportunity to both postmenopausal osteoporosis patients as well as Amgen.
There are currently about 3.5 million patients on Amgen -- on Prolia globally, roughly equally distributed across the regions.
About 1 million in the U.S., about 1.6 million in Europe and the rest of the world about 1 million.
Elderly patients who suffer bone fractures often become bedridden and face potential loss of their independence.
This places an enormous economic burden on society, and less than half of diagnosed patients aren't treated, raising the need for improved education and treatment guidelines.
This is what we, as a company, are focusing on next.
Prolia's average share of treated patients is around 20%, both in the U.S. and globally.
However, there are some countries such as Australia, Switzerland and Ireland, with better diagnosis and treatment rates for osteoporosis, have led to Prolia having 50% share or better.
These are countries who truly understand the societal cost of nonintervention.
Prolia has a strong clinical profile with a proven ability to reduce risk of fractures, combined with solid long-term safety data spanning over 10 years and a convenient twice per year administration schedule.
Prolia will remain an important growth driver and we'll continue to target our commercial efforts on improving diagnosis, treatment rates and duration in order to drive access to a greater number of these patients.
KYPROLIS grew 23% year-over-year, led by our successful launch efforts across existing and new markets outside the United States.
Uptake continues to be robust across these launch markets with a 20% sequential volume growth.
As Bob mentioned, KYPROLIS has developed 2 sets of exciting overall survival data in relapsed multiple myeloma patients this year.
Early in the year, in the head-to-head ENDEAVOR study against Velcade, we demonstrated that the KYPROLIS on, reduced the risk of death by 21%, and improved overall survival by about 8 months compared to the Velcade arm.
Just recently, the ASPIRE study demonstrated that adding KYPROLIS to Revlimid and dexamethasone also reduced the risk of death by 21%, and improved survival by about 8 months.
It is clear, multiple myeloma patients live longer when treated with KYPROLIS.
With these 2 new sets of overall survival data, our message to physicians is simple and powerful: when multiple myeloma relapses, don't put your patient survival at risk, KYPROLIS-based regimens, KRd and Kd reduce the risk of death by 21% versus Rd and Vd, and extended overall survival by 7.9 and 7.6 months, respectively.
This data will also help community oncologists better understand the risk-benefit ratio -- profile of KYPROLIS versus other options.
XGEVA grew 4% year-over-year, mostly due to volume.
We look forward to having the positive multiple myeloma study data added to our label in 2018, which will expand the eligible patient population and provide a new growth opportunity for XGEVA.
For Nplate and Vectibix, we continue to see strong volume growth in both brands.
Vectibix has now over 50% share of the U.S. EGFR segment.
Our recent label update, which includes expanded RAS testing, demonstrates Amgen's ongoing commitment to using cutting edge science and technology to target treatments to patients most likely to benefit.
Turning now to Neulasta.
We continue to drive adoption of Neulasta Onpro, exiting the second quarter with about 55% share of Neulasta sales.
The treatment and convenience benefits to patients and providers is clear.
The penetration continues to improve in patients undergoing minor suppressive chemotherapy regimens.
I'll point out, however, as we look at the cancer therapy in total, PD-1s and other new novel therapies are causing a low single-digit decline in the usage of myelosuppressive agents.
We've also seen a small share loss internationally.
We believe these factors contributed to the year-over-year decline of about 5%.
The quarter-over-quarter decline of 10% was primarily due to heavier purchasing by certain end customers and favorable accounting adjustments in the first quarter.
We expect the trends in myelosuppressive regimens to continue for the remainder of the year.
I'd point out, however, that in spite of decreased use of myelosuppressive regimens, there has been an increase in a number of hospital admissions for febrile neutropenia, and we continue to focus on improving penetration for the benefit of patients and for the reduction of unnecessary hospitalization costs.
Looking forward, I'd remind you that the fourth quarter of 2016 also included a single $38 million purchase from the U.S. government.
NEUPOGEN declined 30% year-over-year.
The impact of short-acting biosimilar competition on NEUPOGEN in the U.S. was in line with prior trends.
We exited the second quarter holding 44% share of the short-acting segment, and importantly, have maintained pricing discipline of the 3-plus years since NEUPOGEN first faced competition in the U.S. We expect the competitive dynamic to continue through the rest of 2017.
Enbrel sales declined 1% year-over-year but increased 24% on a quarter-over-quarter basis.
In the first quarter, you'll recall that market volume growth rates in both rheumatology and dermatology segments have contracted from recent levels.
As expected, in the second quarter, market volume growth improved in both segments.
We expect year-over-year segment growth trends to approximate these recent levels for the balance of the year.
Sequentially, our unit share was relatively stable in both rheumatology and dermatology, declining less than 1 percentage point to 31% in rheumatology and 15% in dermatology.
Changes in net selling price had a positive impact on Enbrel sequential growth.
Recall that quarter 1 was negatively impacted by increased commercial copay assistance.
As calculated on a full year basis, we continue to expect the year-over-year impact of changes in net selling price to be negligible.
We estimate that we exited the second quarter with a balance of about $140 million of excess end-user inventory.
We expect the portion of this excess inventory to deplete through the remainder of the year.
In summary, we saw improvement in the underlying segment performance this quarter versus the prior quarter and our share trajectory continues as previously projected.
Enbrel has a strong track record of safety and efficacy in treating patients with rheumatoid arthritis and psoriasis.
We continue to believe the long-term dynamics are intact and continue to invest in Enbrel to remain competitive in these growing segments.
Aranesp grew 6% year-over-year, primarily from volume growth, which includes the benefit from some timing of tenders in certain markets outside the U.S. versus the prior year.
With EPOGEN, we've been executing our life-cycle management strategy by successfully transitioning much of the dialysis business to Aranesp and extending our supply contract with DaVita through 2022.
The transition to Aranesp is largely complete.
In the second quarter, year-over-year decline in EPOGEN is primarily due to lower net prices as a result of the DaVita agreement.
We believe that, for now, our EPOGEN volume has stabilized.
Sensipar year-over-year growth of 10% was mainly due to net selling price, and to a lesser extent, unit growth.
We continue to await CMS guidance on the reimbursement mechanism for Parsabiv.
Parsabiv launches are underway in Europe with 7 markets so far and 3 more expected by year-end.
In conclusion, let me turn to Repatha.
We continue to extend our market leadership across the U.S. and Europe.
We now hold 58% share of the PCSK9 segments in both markets, with sequential growth points of 4 points in the U.S. and 2 points in Europe.
More importantly, in the U.S., new to brand patient share averaged 70% in the second quarter.
Since March, and the presentation of the positive Repatha outcomes data, we've been engaging with payers to improve the utilization management criteria and processes to improve access for appropriate patients.
Payers and PBMs acknowledge the benefit to patients demonstrated by the outcomes data and are evaluating changes to their processes.
We continue to believe that Repatha will grow steadily as guidelines and clinical pathways are revised and the outcome data are in our label.
We look forward to the publication of the final update of ACC Expert Consensus Decision Pathway, an important reference for physicians.
Cardiovascular disease continues to be the #1 cause of death and disability in the world.
Repatha has the potential to help millions of patients around the world dealing with this grievous illness.
Let me close by thanking all the Amgen staff who worked so hard and tirelessly to get important products to patients around the world.
I'll now pass you to Dr. Sean Harper.
Sean?
Sean E. Harper - EVP of Research and Development
Thanks, Tony, and good afternoon.
I'll begin my comments today with an update on our cardiovascular efforts.
In Q2, we submitted our Repatha outcomes data to global regulators, and we look forward to working with them to include this important update to the prescribing information.
I have also been very encouraged to see multiple professional societies updating their expert consensus documents and guidelines on the use of PCSK9 inhibitors, including the U.S. National Lipid Association, the American Association of Clinical Endocrinologists and the European Society of Cardiology and European Atherosclerosis Society, clearly reflecting the importance of our Repatha outcomes data.
In addition, a draft version of the 2017 update of the ACC Expert Consensus Decision Pathway on nonstatin therapies for LDL cholesterol lowering has recently been made available for public comment.
These decision pathways are intended, among other things, to provide guidance to clinicians in areas where clinical evidence is new and evolving.
While the document is still in draft form, we find the concepts within to well reflect the excellent safety profile and efficacy of Repatha, and to suggest evidence-based utilization in appropriate patient populations.
We expect the final publication of this document in Q3 of this year.
Beyond Repatha, we've advanced our ASGR1 inhibitor into the clinic in the form of an antibody.
As it is just over a year since we first published the strong genetic association of ASGR1 variants with cardiovascular disease in the New England Journal of Medicine, our rapid movement into the clinic demonstrates the speed at which we're able to move programs forward when we have human validation of the sort that deCODE Genetics can provide, to ultimately improve R&D productivity.
We also have additional modalities directed against this target under preclinical investigation.
Our omecativ mecarbil Phase III outcome study in heart failure continues to enroll briskly, demonstrating the interest in an innovative new add-on therapy in an area in which significant unmet need still exists.
And finally, we're looking forward to the presentation of the anacetrapib REVEAL study by Merck to help inform our plans for our own CTEP inhibitor AMG 899.
Turning to oncology.
We recently received our second positive overall survival result with KYPROLIS, this time from the ASPIRE study.
We clearly demonstrated KYPROLIS' superiority to Velcade with improved overall survival in the ENDEAVOR study of KYPROLIS plus dexamethasone versus Velcade plus dexamethasone.
And now we've demonstrated positive survival benefit from KYPROLIS plus Revlimid plus dexamethasone versus Revlimid plus dexamethasone in the ASPIRE study.
In each case, KYPROLIS reduced the risk of death by 21% and improved survival by approximately 8 months, a very meaningful clinical result that reinforces the role for KYPROLIS in driving deep and durable responses.
We have already submitted the ENDEAVOR overall survival data to regulators for inclusion in the labels, and we're preparing the ASPIRE data for submission as well.
And lastly, on KYPROLIS, our Phase III study in combination with Darzalex in relapsed or refractory multiple myeloma began enrolling patients in the second quarter.
At ASCO, we had the opportunity to present Phase II data for our -- from our combination study of IMLYGIC and YERVOY in metastatic melanoma, where we saw an approximate doubling of the response rate compared to YERVOY alone with no unexpected toxicities.
This was an important proof of concept for combining the complementary mechanisms of an oncolytic viral immunotherapy and a checkpoint inhibitor to enhance antitumor effects.
There is significant interest in exploring IMLYGIC with other checkpoint inhibitors in a variety of tumor types.
In regulatory news, we received a February 2018 PDUFA date for our XGEVA submission for the prevention of skeletal-related events in multiple myeloma patients.
We also received full approval for BLINCYTO in the U.S. The approval expands the indication of BLINCYTO for the treatment of relapsed or refractory ALL in adults and now children, and included overall survival data and an indication for Philadelphia chromosome-positive forms of the disease.
Also, within our BiTE platform, we're advancing AMG 673, our half-life extended anti-CD33 BiTE into the clinic, the first in-human testing in AML patients to begin soon.
And lastly, we received a label update for Vectibix to more precisely molecularly define the population with wild-type RAS for treatment in colorectal cancer.
In our bone health therapeutic area, as expected, we've received a complete response letter for EVENITY from the FDA, and will be responding with the data from the ARCH study and the BRIDGE study in men with osteoporosis.
Along with our colleagues at UCB, we're currently in the process of reviewing the detailed ARCH data with experts.
This will be a Class II resubmission in the U.S. which carries a 6-month review time line.
We believe there are patients for whom the benefit risk of EVENITY would be favorable, and we will work with regulators on a path forward.
In our neuroscience collaboration with Novartis, we've submitted erenumab, now known as Aimovig, to global regulators for the prevention of migraine and have received a PDUFA date of May 17, 2018.
We recently presented data from erenumab program at U.S. and E.U. medical conferences and the feedback on the efficacy and safety profile continues to be very positive.
In our beta-secretase program for Alzheimer's disease, we're expanding the development of CNP520 to individuals who carry 1 copy of the APOE4 allele and also have evidence of brain amyloid accumulation.
This will be assessed in an approximately 2,000 subject trial that will be starting soon, and combined with the ongoing Phase III study evaluating CMP520 and APOE4 homozygotes will constitute a robust dataset in an at-risk population.
Given how early beta amyloid starts to accumulate in the course of the disease, we feel that a therapy like a BACE1 inhibitor should be administered as early as is feasible.
This, combined with the strong genetic validation for specifically targeting BACE via deCODE's work, gives us great confidence in our approach.
And finally, in our biosimilars program, we received the unanimous vote from an FDA advisory committee in favor of approval of ABP 215, our biosimilar Avastin, which has a user fee action date in September of this year.
As always, I want to thank our staff for continuing to deliver on these important milestones for the benefit of patients.
Bob?
Robert A. Bradway - Chairman and CEO
Okay, thank you, Sean.
And Skinner, let's open the line up for questions.
Please remind our callers about the process for asking this afternoon.
Operator
(Operator Instructions) Our first question comes from Matthew Harrison from Morgan Stanley.
Matthew Kelsey Harrison - Executive Director
If I could just ask a clarifying question here on Enbrel, that would be helpful.
So I believe you said in the fourth quarter, you had $150 million inventory build, and then I can't remember, I think you either said you had a $20 million or $30 million burn off.
In the first quarter, now you said you're back at $140 million.
So can you just review for us sort of the sequential pattern here?
And did you have an inventory build quarter-over-quarter?
And I guess, should we expect all of this $140 million to burn off in the second half of the year?
How do you expect that to play out?
Robert A. Bradway - Chairman and CEO
Sure.
Thanks, Matthew.
I'll ask Tony to respond.
Anthony C. Hooper - EVP of Global Commercial Operations
Matt, it's Tony.
So let me go back to discussing the inventory.
So inventory, as I said, we report at a point in time, so it's either on the 31st of March or it is the 30th of June, so it's an endpoint.
What we have in hand is we know exactly what the revenue numbers are in terms of ex-factory sales.
We also understand what our in-market demand is based on the IMS retail prescriptions, which are about 90% accurate and 10% predicted.
We also understand exactly what are held by the wholesalers because of our contracts with them and the triangulation between how much has been sold from wholesalers to end users minus the demand, leaves us with a number which we then extrapolate as being the end-user inventory.
So clearly, what happens is at the beginning of the quarter, there's a drawdown of that inventory which we did see in April, May this year, and then there appeared to be a build towards the end of June.
So what I'm saying is we ended the quarter with an excess of about $140 million of inventory which I would expect to burn off the majority of that during the rest of the year.
Operator
Our next question comes from Eric Schmidt from Cowen and Company.
Eric Thomas Schmidt - MD and Senior Research Analyst
Maybe for Sean in this ACC decision pathway document that soon will be coming out here shortly.
Can you just talk about the impact of the decision pathway as relative to the actual treatment guidelines, which I think the ACC expects to put out in 2018?
And also, if you think there's going to be an immediate or relatively near-term impact for the decision pathway document, what payers have to maybe do to comply?
Sean E. Harper - EVP of Research and Development
Yes.
It's a great question.
I mean, I think that in my experience with these documents, the guideline process is one which is slight complex, involves a systematic review of the world's literature by a very large group of international experts and has to kind of occur on a cadence of every 2 to 3 years.
And also the result is if you've ever looked at one of these guidelines, it's a long complex technical document designed for people who are really expert in the field.
Because of that cadence and because of the need to produce something that is more usable to the practicing clinician, these pathway documents emerged.
And they are important reference documents for physicians to think about how to deal with patients who come in and present themselves.
And this is the first time, to my knowledge, that one of these pathway documents has been updated outside of its normal schedule.
And that's because the pathway documents, in part, are designed to deal with just the situation where new important clinical information, particularly the quality of information that's come from both our outcomes trial as well as the Pfizer outcomes trial with PCSK9 have come on the scene and publications have become available.
So it's an important step.
It's -- this is a document that is used quite a bit in clinical decision-making.
And generally speaking, but not always, these kind of changes that you see in these documents then roll in and become incorporated in the formal guidelines, which will come out, as you say, probably '18, late '18, is our best knowledge.
In terms of immediate impact, I'd say, it's a little bit hard to judge.
I think there's an accumulating weight of evidence that the professional societies around the world, including very important ones in the U.S. like the lipid society and the endocrine societies and now ACC, are beginning to converge in their opinions around the importance of LDL lowering and the impact that one sees both the safety profile as well as the efficacy of using Repatha in particular.
And so I do expect that payers will responsibly look at these guidelines and recommendations, and begin to try to make it possible for the doctors who practice in their plans to practice in a way that's consistent with this professional recommendation.
Robert A. Bradway - Chairman and CEO
Eric, why don't we ask Tony to share a few thoughts as well on the payer perspective in your question.
Anthony C. Hooper - EVP of Global Commercial Operations
So I mean, it's clear to us, Eric, that in our discussion with the payers, they do pay very careful attention to position papers and the guidelines coming from these bodies.
And the National Lipid Association is a subdivision of the AHA, so it's clear they're making those decision on that regard.
The ACC, of course, has always been the granddaddy of guidelines and people will pay definitive attention and look at how they will be actually serving patients aligned with these position papers or pathways that the ACC have put into place.
So we're working extensively with them at the moment.
As Sean said, as the weight of evidence continues to build around the importance of delivering Repatha to patients who do have this particular disease.
Operator
Our next question comes from Ying Huang from Bank of America Merrill Lynch.
Ying Huang - Director in Equity Research
My first one has to do with the balance sheet.
You have a $39 billion cash on balance sheet.
If you guys don't have any plans to -- concerning M&A transactions or repay the debt, many investors is wondering whether you have any plans to repurchase a significant portion of the float, the shares?
And then maybe for Sean, when might you know whether FDA would require a cardiovascular safety study for romosozumab?
And if so, would you continue the development or not for romosozumab?
Robert A. Bradway - Chairman and CEO
Okay.
Ying, why don't I take the first question.
Invite David to add any color if he'd like.
And then Sean, you can briefly answer the romo question.
On -- with respect to balance sheet, I think, again, you're aware our business is generating significant cash flows.
We have a track record of wanting to use that cash flow to pay dividends to our shareholders, a rapidly growing dividend as well as to buy back stock and to invest in the business.
So we're optimistic about the outlook for the business, as I say, continue to generate strong cash flow, we have a strong balance sheet and we'll look at ways of deploying that capital as appropriate through time.
And David, maybe you'd like to update on where we are with respect to the capital commitments that we've made or share.
David W. Meline - CFO and EVP
Yes.
So I would just add to that 2 things.
One is that we continue with the plan, as I said, to return 60% of net income through '18 to shareholders, and I think that is certainly something we'll execute on going forward.
And I think the second point, as many know, the vast majority of the cash that we're holding does sit offshore.
And we don't see right now that it would be appropriate to repatriate it under the current U.S. tax system.
So obviously as and when they make progress on tax reform and make it more reasonable to consider repatriation, would we then take a look and start providing some commentary on how we might deploy that.
Sean E. Harper - EVP of Research and Development
And with respect to romosozumab, I think we're -- it's just too early in the process to comment meaningfully on whether additional studies would be appropriate and whether they would be a good investment for our shareholders and UCB shareholders.
We have to go through a process that's going to take some time to discuss these results formally with regulators.

Our next question comes from Terence Flynn from Goldman Sachs.
Terence C. Flynn - MD
Maybe two part from me.
Just wondering, following the romo safety signal, if your BD priorities have changed at all either with respect to size, stage or disease areas of interest?
And then on the guidance, just wondering if you can talk about the changes on the revenue side, particularly lowering at the top end, what the driver or drivers of that was.
Robert A. Bradway - Chairman and CEO
We'll do this in 2 parts as well then.
With respect to romo and the impact on our BD thinking, I don't think it has any direct impact, Terence on how we're looking at the opportunities of business development.
And David, do you want to talk a little bit more...?
David W. Meline - CFO and EVP
Sure.
In terms of guidance, if you might recall, when we entered the year, we provided revenue guidance that was broader than traditionally we would have because of, in particular, the uncertainties around the evolution of the sales of Repatha which related to this question of the outcomes trial being published as well as the ongoing litigation that's taking place.
And so now as we sit at midyear and look at the trajectory of the business, the good news for us is the revenue is evolving as we'd set out for the company through the year.
And indeed, the earnings performance is quite good and we've raised again our EPS for the year.
So really, what we're doing now is we're narrowing the guidance to reflect the fact that as we look to the balance of the year, we don't have the most positive upside that might have occurred if there had been an early decision on the litigation.
We are awaiting the outcome of that, and then we're also reflecting the trajectory which we're encouraged by the uptake of Repatha, which we think will continue to accelerate.
And so the guidance simply reflects the best estimate we have right now.
Operator
Our next question comes from the line of Michael Yee from Jefferies.
Michael Jonathan Yee - Equity Analyst
My question is in relation to your longer-term guidance and your margin guidance, 52% to 54%, you're at the higher end of that.
And next year, you're not necessarily going to face so much biosimilar competition.
So can you talk about where and when you could think about reassessing that?
And importantly, if you think that these margins can be sustained or managed even in the face of potential future biosimilar risk?
Robert A. Bradway - Chairman and CEO
Sure.
Yes, so I would say, first of all, you're correct on our margin performance.
We've been pleased with how it's evolved for the company, given that we set that goal out at a time we were delivering 38% operating margin.
So it was quite a big task for the company but you've seen it evolve very nicely.
And I think, importantly, for us, during that time, we've also stood up a very significant cardiovascular franchise.
We're in the process today of investing in preparation of our first launch in the neurology sector.
We've been building out and are on track with our portfolio of biosimilars, and we've added several hundred million dollars a year of structural costs to our international network as we build out globally.
So not only are we seeing margin improvement, but also we've been building a base for the company which is going to be very important for our sustainability going forward.
In terms of as and when we would then look forward and what do we think about margins for the company, I would say we're approaching now the end of the period that we gave guidance through '18.
So obviously, within this next year, 1.5 years, we'll have a look and start providing some additional views of the future for the company.
But at least as we sit here today, we feel very good about not only the performance of the company and the prospects, but also the sustainability of that profitability.
Operator
Our next question comes from Geoffrey Porges from Leerink Partners LLC.
Geoffrey Craig Porges - MD, Biotechnology, Director of Therapeutics Research and Senior Biotechnology Analyst
I just want to have a little discussion on Aimovig or hear your thoughts on it.
You've said that you're likely to be first and I know you can't really comment on pricing.
But certainly, the PCSK9 experience was sobering for all of us in terms of the payer response.
And I'm just wondering how your discussions with payers are going?
What sort of step edits you would expect for people to get access to Aimovig?
And then should we be expecting pricing that's more at the Prolia end of the spectrum?
Or more at the Repatha end of the spectrum?
Anthony C. Hooper - EVP of Global Commercial Operations
So Geoff, this is Tony.
I mean, one, we have never given pricing guidance prior to a launch.
Aimovig is going into a patient population that are uniquely different from a symptomatic perspective, right?
So they -- we estimate about 3.4 million patients presently on prophylactic treatment for migraine, both episodic and chronic, which is a crippling disease resulting in mothers not being able to be mothers, or employees not being able to do their work.
And our discussions have been with payers, from a clinical perspective at this particular stage, as we move things forward.
And there's a huge unmet need and we're busy developing our pharmacoeconomic value-based pricing models for this particular disease.
It's going to be a competitive market, that we understand.
But our pricing will be made as we get closer to the launch time.
Operator
Our next question comes from Ian Somaiya from BMO Capital Markets.
Mayur Amrat Somaiya - Analyst
I was just trying to better understand the drivers of Repatha until we get to the publication of the ACC treatment guidelines at the end of next year.
Specifically, just 2 different -- 2 subgroups that payers and physicians have a lot of interest in.
Seeing results for diabetic smokers.
And then just separately, at the time of the ACC presentation, the follow-up was roughly 2.2 years, was wondering when we could see follow-up or data following patients for greater than 3 years?
Robert A. Bradway - Chairman and CEO
Okay.
Why don't we do this in 2 parts.
Tony, why don't you talk a little bit about what we expect to see between now and when we have the outcomes data and the label, what the drivers are.
And then Sean, you address the follow-up question.
Anthony C. Hooper - EVP of Global Commercial Operations
So when we look at the actual usage in the marketplace, right, there are 3 patient segments that are popping to us that are clearly indicated inside the label and where physicians start to understand there's important to treat, right?
These are patients who have ASCVD, who've had 2 events in the last 24 months, clearly high-risk patients or what we call high, high-risk patients.
There are those who have ACS who have had an event in the last year or so with ASCVD.
And then there's the FH population.
That's a fairly large population and we've seen the majority of our patients coming from that group at the moment.
If you look at the NRx data, which is really looking at the new to brand prescriptions in terms of new patient capture, you are seeing that we're gaining market share there and gaining traction consistently in terms of getting patients.
When you look inside the data and you see that the abandonment rate by commercial patients has gone down to about 24%.
It's clear that we are assisting patients who can't afford their copay or their deductibles, so we're getting a higher access to patients there.
So we see a continued usage and expansion by existing physicians.
We're capturing about between 300 and 400 new prescribers per month, so the prescriber base is growing as we go forward.
The new guidelines will start to take a little bit of traction for physicians to understand.
We look forward to the ACC presentations.
So that's where we see the growth of our business right now.
Sean E. Harper - EVP of Research and Development
And then with respect to the insights into the data on diabetics and smokers, there were a very substantial portion of type 2 diabetics in FOURIER and about 30% of the population were smokers.
And essentially, when you look at those subgroups in comparison to the whole study, the data were virtually identical.
So there we did see, as you might expect with LDL lowering and as has been seen with statins, that it has to be sort of uniform effect across these type of clinical populations.
Obviously, the controlled portion of the FOURIER study is complete but there is, I think, you're referring to long-term extension kind of data that is available.
As you might recall, we had over 4 years of long-term extension data, treatment data at the time of presentation of FOURIER published at that time in one of the major journals.
And we have a long-term extension of approximately 5,000 patients from FOURIER as well who will run out for an additional number of years, perhaps up to 10, we'll figure that out as we go along.
But that is designed to be a leading indicator of any safety issues that might not have presented themselves in the window of the FOURIER study, which was, as you point out, just 2.2 years.
Operator
And our next question comes from Geoffrey Meacham from Barclays.
Geoffrey Christopher Meacham - MD and Senior Research Analyst
I have one on Repatha for either Sean or Tony.
And I guess, the question is more in demand trends post-ACC in this year.
I'm just trying to get a sense for when payer policy and guidelines become more favorable?
If you guys would expect any hurdles at the actual prescriber level at the cardiovascular, at the treating physician level?
Or if patient persistent rates over time have really changed materially?
Anthony C. Hooper - EVP of Global Commercial Operations
So Geoff, let me take that one as best I can at the moment.
So just to remind you that the outcomes data were presented at the ACC in March, we are not promoting that data at the moment.
We are clearly awaiting the FDA decision to include the data in our label at which stage, we will start being able to promote that data into the marketplace.
So we are working consistently with the payers at the moment in terms of reevaluating and challenging some of the utilization management criteria, challenging some of the onerous processes that are in place and actually working with the professional bodies themselves, so they become involved in ensuring they can get access to their patients.
We have seen a high level of willingness from the payers and the PBMs to relook at the utilization management criteria to ensure that the processes are reasonable.
The cohorts are probably a bit too small to be able to really understand patient persistency at the moment.
So what we are tracking is new patient capture early on.
And as you know, you can see that quite easily from the IMS data and that continues to grow as well as to grow trialists as we go forward.
We do believe that once the FDA ratifies the data and puts it in the label, we'll be in a much better decision to see an opening of access through the payers.
Operator
Our next question comes from Cory Kasimov from JPMorgan.
Cory William Kasimov - Senior Biotechnology Analyst
I wanted to follow up on erenumab.
And on their call this morning, Lilly mentioned that they haven't seen any competitive CGRP data that they view as better than what they've generated.
So I'm wondering if you can talk a little bit about how you see this market?
And how you maybe plan to potentially differentiate erenumab or Aimovig, in this set as you begin to get a better feel for the various profiles of other agents in the class?
Or is this something that really just comes down to first to market and potentially price as you were asked about before?
Anthony C. Hooper - EVP of Global Commercial Operations
Okay.
So let me start doing a little bit of an answer there, if I can and perhaps Sean can add around the clinical data, right?
So just to go back, my comment to Geoff earlier on around the unmet need.
The more we dig into this market, the more you realize that not only patients, but specialists, physicians themselves have been absolutely frustrated for decades because of the inability to actually prescribe a migraine drug for a migraine.
They've used substitutes.
They've used drugs that have caused huge side effects and patients are unhappy with them.
So as we talked to patients, patient bloggers, patient groups about their needs, it's clearly unmet need continues to be large.
Every specialist I've spoken to that looked at the Aimovig data has been impressed by the data, has seen a dramatic potential change in what this will do for patients on their day-to-day lives.
We do believe that we will be first to market.
We have submitted first.
We intend coming to market first.
We have a partnership with Novartis, who have an existing strong relationship with the neurologists, a lot of them who treat migraine.
And we expect to be using their skills, competencies and relationships to set us up and to move fast and quickly into the marketplace.
Sean E. Harper - EVP of Research and Development
And my only additional comment would be that because the other agents are not receptor antagonists and are ligand directed, they're less potent and the amount of antibody required to achieve the clinical effect is considerably higher.
This results in things like loading doses or IV administration or multiple large volumes subcu administrations required at the same time.
And none of those are positives for patients.
So we know we can get erenumab to a monthly single, small volume, well-tolerated auto injection.
I don't know that that's possible with these other agents.
The data, as it appears to me at this point, doesn't suggest that.
Operator
Our next question comes from Robyn Karnauskas from Citi.
Robyn Karnauskas - Director and Senior Analyst
Given the pushback So far with the payers in the cardiovascular space that you've seen with Repatha, like how are you thinking about the bar for developing your CETP inhibitor?
And what threshold do you want to see with the Merck data that will make you feel more positive about the prospect of the class?
Robert A. Bradway - Chairman and CEO
I think we're focused, Robyn, on unmet medical need and trying to figure out whether that class of agents has a role to play.
But Sean, I'll let you talk about the specifics.
And obviously, we need to believe that we can earn a return on any further investment there for our shareholders.
Do you want to talk about the clinical?
Sean E. Harper - EVP of Research and Development
Yes -- No, I mean, I think that it's the case, that if we were to see, as we did with the PCSK9 that has been assessed in outcomes trials, a linear relationship has occurred with statins between LDL lowering and event rate risk and the agents are lowering LDL in the range of 30% to 35%, 40% that an oral agent that could do that as an add-on to statins would be a meaningful drug to have in our armamentarium.
It's obviously not going to deliver the kind of LDL reductions you can achieve with a PCSK9 antibody, but because the drugs are oral, so we feel they play a role.
What remains to be seen is whether that these agents, based on their LDL-lowering capacity, and the Merck drug will be the first that I think will answer this question more definitively, whether we see that relationship or whether we're seeing some fractional effect of that relationship and that the effect on cardiovascular risk is marginal.
In which case, obviously, we'd be much less excited about pursuing this.
So I think it much depends on the details of the reveal data.
Operator
Our next question comes from Umer Raffat from Evercore ISI.
Umer Raffat - Senior MD and Fundamental Research Analyst
Just to focus on the PCSK9 a bit.
In the scenario where there's no meaningful inflection for Repatha, post-guideline update, would you potentially consider the idea of a pricing reset?
And then also, do you think Novartis' CANTOS data impacts PCSK9 opportunity at all?
Was very curious to have your take on it.
Anthony C. Hooper - EVP of Global Commercial Operations
So Umer, this is Tony.
I think a lack of inflection would be a terrible tragedy for those patients who suffer from this disease and who will either be suffering an early untimely heart attack or stroke.
The price we came to market was clearly aligned with an understanding about the rebates that will be required in the marketplace to gain a competitive position.
When you look at the data we presented at the ACC in March this year, we clearly talked about the pharmacoeconomic value of this product, our PCSK9 within the class and reconfirms that our net price to payers is presently very much in the range of a pharmacoeconomic price.
We continue to believe that this drug brings value.
When you look at the second year data that you're reducing heart attacks by 35%, reducing stroke by 24%, 27%, it is an enormous crack in this disease that takes lives on untimely basis.
So we will continue to drive it forward and to ensure that the value we bring is distinct and beneficial in the marketplace.
Sean E. Harper - EVP of Research and Development
And with the IL-1beta data from the Novartis trial, I think we just have to wait to see the data to understand.
But I don't expect that to have a direct impact on lipid-lowering approaches.

And our next question comes from Salim Syed from Mizuho Securities.
Salim Qader Syed - MD, Senior Biotechnology Analyst of Equity Research & Head of Biotechnology Research
I have one on biosimilars.
So you guys have 10 now in development, I believe, and you've seen success -- with first 3, HUMIRA, Herceptin and Avastin.
Can you just remind us what is your situation with manufacturing capacity?
Do have capacity for all of these?
Or will you need to expand and what the path there, would you have to go outside and use a CMO?
Or would you build it yourself?
Robert A. Bradway - Chairman and CEO
Salim, we're in good shape with respect to our biosimilars.
Again, one of the reasons we committed to this was a growth opportunity for the company, was our belief that we do the large-scale manufacturing of proteins very well.
So we're deploying our process development manufacturing skills, and we're in good shape for our programs.
Operator
Our next question comes from Alethia Young from Credit Suisse.
Alethia Rene Young - Research Analyst
Just one for Sean.
Maybe if you can talk about some of the earlier things in your oncology pipeline?
And how you're developing IO?
And do you think you need some of the more traditional assets like PD-1 or any of the other ones (inaudible) that people are going after?
Sean E. Harper - EVP of Research and Development
Yes, I mean, I think, right now, we're very interested in our BiTE platform.
We've made a strategic decision to focus primarily in bispecific T-cell engaging, not ADCs.
And we do have a limited but important effort, of course, in collaboration with Kite on CAR T cells.
The BiTE platform is moving along quite significantly and because of the timing, if you think back when we acquired the technology and how long it takes, we have a big wave of these molecules directed at hematologic and solid tumors moving into the clinic over the next 18 months or so.
We have, of course, half-life extension technology that we've added to the majority of these at this point.
So that is a very important, as you point out, there'll be the opportunity to combine them in many cases with checkpoint inhibition.
From an R&D perspective, we've had no trouble at all getting partners to do these experiments with us providing the PD-1 and often sharing the actual cost of the trials with us.
So that's not been an issue.
And then the other area we're still very excited about is T-VEC, particularly now as we begin to explore hepatic injection, different tumor types in combination with checkpoint inhibition.
It opens up a range of tumor types to explore, including those that don't respond well to checkpoint inhibitors without immunization strategy.
And then the last one I'd mention is our CSF-1 antibody is in combination right now with Merck's PD-1.
And we're very excited about that program as well.
So in terms of pure immuno-oncology, those would be the ones that I'd highlight.
Robert A. Bradway - Chairman and CEO
Big picture, Alethia, is that we see a lot of excess capacity.
So I think, it's 2 dozen, maybe even 25 different PD-1/PD-L1s are competing now for space in oncology.
So we're unlikely to jump in, we're watching this space carefully.
But looks to me like there's a lot of excess capacity right now in that area.
Operator
Our next question comes from Ronny Gal from Bernstein.
Aaron Gal - Senior Research Analyst
Just a question on 340B program, we're talking to folks in the hospital channels, they're talking about expanding their outpatient services out of this portion of shared hospitals.
Could you just comment about how big this is for your business?
What do you see the trend line?
And what do you expect the impact would be of the CMS proposal to reduce the reimbursement rate?
Anthony C. Hooper - EVP of Global Commercial Operations
Ronny, it's Tony.
I don't have those exact numbers with me.
We can get back to you.
But obviously, a lot of our oncology business is in the institution which falls under 340B, and we watch that business carefully.
It has grown quite dramatically in the last 3, 4 years or so.
But I think it's sort of under 20% of our total business would be 340B.
Robert A. Bradway - Chairman and CEO
Closer to 10% of the business, Ronny.
And the trade associations, as you know, bio and pharma have been very focused on this.
I think as the program that got launched with noble intentions but it's one that's subject to some abuse.
And so there's, as you know, some oversight focus in this area right now on Capitol Hill, including looking at -- whether the discounts are being appropriately applied to the patients that are most in need of them, et cetera.
So I'd say stay tuned.
This is an area that is likely to be evolving here over the coming legislative calendar.
Operator
Our next question comes from Jim Birchenough from Wells Fargo Securities LLC.
James William Birchenough - MD and Senior Biotechnology Analyst
You've mentioned value-based pricing a few times with regards to the CGRP category and Repatha.
Could you maybe talk about what you're hearing from payers in terms of how set up they are for that kind of model?
And in migraine specifically, could you see some sort of contracts that are based on a certain level of migraine reduction?
Anthony C. Hooper - EVP of Global Commercial Operations
So Jim, the value-based process is defining the value of a product based on the threshold you set for quality of life you save.
It's a process used by most health technology assessment countries around the world such as the U.K., Canada and Australia.
It's an evolution of a process in the U.S. at the moment.
And we feel quite robust and confident in our ability to establish that type of range of value for a product.
We discussed that with the payers on an ongoing basis.
I think what you might be referring to is a bit of our risk-share contract we've actually put in place and those are interesting ones, too.
We have product that deliver a distinctive value and we prepare to put our money where our mouth is with those particular products.
Some payers have taken those up such as Harvard Pilgrim.
Others are trying to work at how do they track that, monitor that, as they go forward.
But I would imagine going forward, it has to be something that becomes more and more popular.
Operator
Our next to last question comes from Andrew Peters from Deutsche Bank.
Andrew Ross Peters - Director
Quick one from me.
Just wanted to see if you've seen an inflection in the rate of Repatha rejections or approvals since FOURIER?
And do you think that's really the biggest driver of kind of the share increases that you've seen against alirocumab?
Or is it something else that you see in the market?
Anthony C. Hooper - EVP of Global Commercial Operations
If you could turn to Page 23 of your slide deck, that's, of course, the chart I look at often, which shows a distinctive movement of our market share since the outcomes data were delivered at the ACC in March.
Clearly, people understanding the value of this drug in terms of long-term treatment.
So we have, in the interim also worked hard, as I said earlier, to try and reduce the impact on patients who have large commercial copays or large commercial deductions.
And we're working consistently with payers to try and make the utilization management criteria as well as the process to get access to drug more reasonable to ensure appropriate patients get access.
Operator
And our final question comes from Carter Gould from UBS Equities.
Carter Lewis Gould - Large Cap Biotech Analyst
For Tony, maybe just taking a different direction, can you help frame for us the magnitude of the incremental commercial opportunity for moving XGEVA into myeloma?
And any nuances we should keep in mind in looking at the peak penetration in the U.S. versus Europe?
Anthony C. Hooper - EVP of Global Commercial Operations
You guys can see the size of the multiple myeloma market based on the patient numbers themselves.
So there's a distinctive population that exists over there.
It's a population that presently isn't in our label, and therefore, we have not been able to promote on that particular patient group.
And we look forward doing it early in or whenever we get another label in 2018.
Robert A. Bradway - Chairman and CEO
February PDUFA date.
And Sean, you might just want to remind Andrew and others of the benefits we believe that XGEVA will provide those patients with multiple myeloma.
Sean E. Harper - EVP of Research and Development
Yes, I mean, as you probably are aware, virtually all myeloma patients, because of the secreted protein that characterizes the disease filters into the kidney have varying degrees of renal insufficiency and have to have dose reductions or simply can't tolerate drugs like zoledronic acids.
So there is an obvious need for a product that doesn't have renal clearance such as denosumab.
However, in our original applications with denosumab, we had a subgroup of patients in one of the trials of multiple myeloma where it appeared as though there could be a harm signal on overall survival.
It was a subgroup analysis.
It was unlikely to be real.
We've, of course, demonstrated it wasn't real by doing this large trial that we've filed.
And once we have the indication, we can promote it and so on, I think the utilization that's been hampered by that concern about impact on the actual disease process will be alleviated, and there, it should be a great advance for patients with multiple myeloma to have more access to denosumab.
Robert A. Bradway - Chairman and CEO
Okay.
Carter, thanks for that question.
Thank you all for joining the call.
And I also want to thank our worldwide staff who are busy successfully executing on our strategy and operating the business right now really effectively, while both delivering for patients and shareholders.
So I hope you can see from our results that we're positioned for the changing competitive environment with the benefit of a new product cycle set to drive volume growth and a strong balance sheet that we intend to deploy to create value for our shareholders.
We see both of these as key to sustaining long-term growth with Amgen.
