Good day, and welcome to the Bristol-Myers Squibb 2017 Second Quarter Results Conference Call.
Today's conference is being recorded.
At this time, I'd like to turn the conference over to Mr. John Elicker, Senior Vice President, Public Affairs and Investor Relations.
Please go ahead, sir.
John E. Elicker - SVP of Corporate Affairs and IR
Thank you, Hannah, and good morning, everybody, and thanks for joining our call to discuss our second quarter earnings.
With me this morning are Giovanni Caforio, our Chief Executive Officer; Charlie Bancroft, our Chief Financial Officer.
Both Giovanni and Charlie will have prepared remarks.
Also joining are Murdo Gordon, our Chief Commercial Officer; and Tom Lynch, our Chief Scientific Officer, who obviously will be here for Q&A.
And before I turn it over to Giovanni, I'll read the safe harbor language.
During the call, we'll make statements about the company's future plans and prospects that constitute forward-looking statements.
Actual results may differ materially from those indicated by these forward-looking statements as a result of various important factors, including those discussed in the company's SEC filings.
These forward-looking statements represent our estimates as of today and should not be relied upon as representing our estimates as of any future date.
We specifically disclaim any obligation to update forward-looking statements even if our estimates change.
We'll focus our comments on our non-GAAP financial measures, which are adjusted to exclude certain specified items.
Reconciliations of these non-GAAP measures to the most comparable GAAP measures are available at our website.
Giovanni?
Giovanni Caforio - Chairman of the Board & CEO
Thank you, John.
Good morning, everyone.
I'm really pleased that we just finished another strong quarter.
Our non-GAAP earnings per share were $0.74, which is a 7% increase over last year.
And we grew our revenue by 6%, with double-digit growth across our key growth drivers.
Now before I go into more detail, we all know that a competitor announced data this morning that is clearly important to the market, so let me make a few comments.
First, our CheckMate -227 is a first-line non-small cell lung cancer program, not just one trial, investigating several important scientific questions.
In Study -227, we have at least 3 discrete opportunities for success.
We will be able to evaluate the combination of Opdivo + Yervoy, we will evaluate Opdivo plus chemo in PD-L1 negative patients and we will be able to evaluate Opdivo plus chemo in all comers.
Additionally, as you know, we are testing 2 cycles of chemo with the combination of Opdivo and Yervoy.
It's also important to recognize that MYSTIC trial and CheckMate -227 are very different trials.
First, the dose and schedules are different.
In -227, we believe we have optimized the dose and the schedule.
Second, the trial sizes are very different.
Study -227 enrolled over 2,200 patients, with 1,200 patients in PD-L1 positive portion alone.
In contrast, MYSTIC enrolled roughly 1,100 patients in all comers and its primary endpoint was evaluated in a subset of that population.
While the MYSTIC results are important data, and we look forward to seeing more, it's very difficult to read across trials.
So let me now get back to our results this quarter.
Globally, Opdivo sales were very strong.
In the U.S., Opdivo delivered strong performance in an increasingly competitive market.
Shares in the second-line lung cancer market remained stable, and we saw continued strong performance in other tumor types with encouraging trends in head and neck cancer.
Internationally, we delivered very strong growth, as we leveraged broad reimbursement and strong commercial execution to drive continued adoption in our key markets.
We also saw important progress from a regulatory and from a clinical perspective.
Earlier this month, we announced results from CheckMate -238, which was stopped early, as Opdivo demonstrated superior recurrence-free survival in the adjuvant setting of melanoma versus Yervoy, the current standard of care in this setting.
This is another successful registrational trial with Opdivo, and it's an important validation of our strategic approach to moving treatment earlier in the adjuvant setting, which we are exploring across tumors.
In Europe, Opdivo achieved 2 important approvals, 1 in head and neck cancer and 1 in advanced bladder cancer.
In the U.S., the FDA accepted for priority review our application for second-line hepatocellular carcinoma, the most common type of liver cancer, and we have a PDUFA date of September 24.
And you saw that we just filed the sBLA for 4-week dosing for Opdivo monotherapy, and we look forward to making that dosing available to patients and physicians.
ASCO is always an important meeting for us.
From my perspective, there were 2 key themes at this year's meeting.
First, we saw the emergence of the next wave on immuno-oncology agents that have the potential to complement validated mechanisms, such as PD-1 and CTLA-4.
Assets like LAG-3 and IDO underscore the potential of our deep pipeline and our expertise in this area.
Second, it was clear the translational research and biomarkers are likely to play a critical role in identifying which patients would benefit most from different therapies or regimen.
This work is important because we know that the unmet need in cancer remains high and that there are many patients we are not reaching.
And we believe our pipeline of I-O assets positions us well to bring forward the right medicine or regimen for the right patient at the right time.
Looking forward over the next 12 months or so, we have important data readouts expected from our portfolio, including in renal cancer, HCC, small cell lung cancer and, of course, non-small cell lung cancer.
Outside of oncology, execution also continues to be strong.
Eliquis delivered 51% growth, continuing to extend its lead in the expanding NOAC class.
Our hepatitis C regimen was approved and recently launched in China, making it the first regimen of its kind in this important market.
Orencia and Sprycel sales remained strong, having again delivered double-digit growth.
We also saw continued progress in our diversified portfolio from a regulatory and from a clinical perspective.
We've made good progress on FGF21, where we are in discussion with health authorities about our registrational program, which we intend to start by the end of this year.
Orencia received approval for psoriatic arthritis in the U.S. and in Europe, and we expect 2018 to be an important year for our immunoscience pipeline, with potential data readouts for the TYK-2 and the BTK programs.
Finally, following our IP settlement with Merck earlier this year, together with our partner, Ono, we've just taken additional legal action against a number of companies with commercialized PD-L1 products.
As we've said before, we have established a strong IP position with respect to anti-PD-1 and anti-PD-L1 that we will vigorously defend.
Similar to the Merck action, we are seeking financial remedy and not to reduce patient access to these medicines.
As the innovators in this field, we have made significant investments in developing the science of I-O, and we are proud of the transformative benefits it is bringing to cancer.
As I look back at the first half of the year, I'm very pleased with the execution across the company.
We've reported strong sales performance, and we have seen good progress from a regulatory perspective and from a clinical perspective.
Looking ahead, I see tremendous opportunity for us to continue our growth, and I am confident that we are very well positioned for the long term.
And with that, I'll turn it over to Charlie.
Thank you.
Charles A. Bancroft - Executive VP, CFO & Head of Global Business Operations
Good morning, everyone.
As Giovanni described, we delivered strong results during the quarter, driven by solid execution across the company.
Let me first provide some color on the performance of our key products, starting with Opdivo.
During the quarter, we saw continued growth for Opdivo in the U.S., with a year-over-year increase of 19%.
We're very pleased with this performance, particularly given the increased competition in the market across the range of approved indications.
Specifically, in second-line lung cancer, we maintained roughly 40% share as we exited Q2.
Outside of lung cancer in the U.S., the trends in renal cell remain strong with approximately 50% share, and we are seeing early signs of acceleration in head and neck.
Given the current trends and strength of our business in the first half of the year, we believe that Opdivo will grow in the U.S. compared to 2016 despite pressure in the second half of this year due to the competitive dynamics in both first- and second-line lung cancer.
Internationally, sales of Opdivo were up 17% sequentially as we continue to see adoption across second-line non-small cell lung cancer and renal.
Outside of these tumors, we are in the process of launching Opdivo in head and neck and bladder in several markets where we already have secured reimbursement, including Germany, Belgium and the Netherlands.
With respect to the combination of Opdivo and Yervoy in melanoma, in the U.S., share for the combination remains stable with use in roughly 1/3 of first-line patients.
Internationally, access in reimbursement approvals for the combination facilitated greater adoption, resulting in 24% year-over-year growth in Yervoy sales.
As Giovanni mentioned, Eliquis delivered strong growth and is leading new-to-brand share in both the NOAC and OAC class.
Given the strength of our data, including the real-world outcomes data presented over the last 2 years, we believe we have significant opportunity for continued growth.
Internationally, Eliquis delivered strong growth of 42% compared to the same time last year and continued to outpace the growth of the NOAC class in key markets around the world.
Eliquis is the #1 NOAC in new-to-brand share in countries such as Germany, France and the U.K.
Orencia and Sprycel delivered worldwide double-digit growth year-on-year as we continue to drive demand growth for Orencia in the early rapidly progressing patient segment of RA.
With respect to Sprycel, our first-line new patient share remained strong.
Now I'd like to highlight a couple of items from our non-GAAP P&L.
As I've described in the past, our gross margin is sensitive to product mix.
During the quarter, we saw continued growth in Eliquis and declining performance from our virology portfolio, together pressuring our margin.
With respect to operating expenses in the quarter, SG&A was down 6% while R&D was up 5%.
This dynamic reflects our commitment to strategically manage our expenses to ensure we can invest in the most important opportunities for our company with R&D as a key priority.
Just a couple comments on capital allocation.
Business development remains a top priority, and the second quarter was very active.
We executed multiple transactions, including collaborations to expand our biomarker science in I-O with QIAGEN and to study potentially registrational clinical collaborations in combination with Opdivo.
In addition, we completed the $2 billion ASR during the quarter.
And as I previously outlined, we plan to conduct additional share purchases during the second half of the year at roughly $250 million per quarter.
Turning to guidance.
Given the strength of our business in the first half of 2017, we are raising the floor on our non-GAAP EPS and are now guiding to $2.90 to $3.00.
In closing, we believe our marketed portfolio and pipeline have significant potential.
We've delivered very solid results in the first half of the year based on strong execution across the company, and we will continue to focus on investing in the highest-priority opportunities across the portfolio.
I'll now turn it back to John for Q&A.
John E. Elicker - SVP of Corporate Affairs and IR
Thanks, Charlie, and thanks, Giovanni, for the comments.
Hannah, I think we're ready to go to the Q&A.
Operator
(Operator Instructions) And we'll take our first question from Jami Rubin with Goldman Sachs.
Jamilu E. Rubin - Equity Analyst
Tom, I have a question for you.
And Giovanni, I appreciate your spelling out the differences between the MYSTIC trial and CheckMate -227.
But Tom, just curious to know your level of confidence in just the general CTLA-4 thesis in light of the MYSTIC results.
I note that there are a couple of other really important frontline studies with Yervoy and nivo that could report later this year, renal; and next year, head and neck.
So just if you could comment generally about the role of CTLA-4 and your confidence in this asset.
It's very hard to walk away from MYSTIC feeling warm and fuzzy about -227.
So I'm just wondering if you could kind of talk big picture about that particular strategy.
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
Well, Jami, thanks so much for your question.
And what I'd like to do is sort of start off by making a couple of comments about lung cancer in general, and then address specifically the thoughts about CTLA-4, because I do think it's an important data to emphasize how we look at CTLA-4.
So as I've said many times, Jami, lung cancer is an unbelievably difficult disease to treat.
I've been at it for 30 years, and I continually am struck by how challenging it is to make progress in this disease.
I think, as Giovanni outlined in his comments, one of the key things about Bristol-Myers is we have a comprehensive program in lung cancer.
We're not wedded to any one approach.
We have optionality with monotherapy in first line.
We have combinations of Opdivo and Yervoy in first-line lung cancer.
We also have Opdivo, Yervoy combined with chemotherapy as well as Opdivo combined with chemotherapy in first-line lung cancer.
So Study -227, along with its new cousin, Study LA9 (sic) [9LA], are really a family of studies that we hope are going to demonstrate what the best opportunity in lung cancer is in first line.
And so let me just comment on CTLA-4 as a mechanism.
As an oncologist, what really matters to me is -- are drugs that impact overall survival.
And CTLA-4 is one of the 2 drugs in immuno-oncology that has been shown to impact overall survival.
And let's just think about it.
In Phase III, we had data this year, that shows in melanoma that Opdivo and Yervoy has a survival advantage in patients with melanoma.
The NCCN has endorsed the combination therapy in small cell lung cancer and in mesothelioma.
We have Phase II studies that shows strong signals in renal cell cancer and MSI-high colorectal cancer.
And again, just in the next 12 months, you're going to be seeing nearly 5 large Phase III trials, where we're looking at CTLA-4 plus Opdivo in renal cell cancer, head and neck cancer and small cell cancer, in addition to what we're talking about in non-small cell lung cancer.
So we believe that CTLA-4 is an important mechanism.
In fact, Jami, not only do we think that Yervoy itself is important, but we've also invested in a nonfucosylated new formulation of CTLA-4.
And we're partnering with CytomX to look at a Probody for CTLA-4.
So I think as an oncologist, as a clinical researcher, when you see an agent that's associated with a survival advantage, I think it's important to find out what is the optimal way to use this drug and how can we improve outcome for our patients.
And one of the things that we become very aware of is dosing schedule are important when you combine I-O drugs and I think that we feel certainly in -227 that we have a good dosing schedule for our patients.
Operator
We'll go next to Chris Schott with JPMorgan.
Christopher Thomas Schott - Senior Analyst
And just a couple additional follow-ups given the MYSTIC update.
So just a couple here.
So first, when you reflect on the various differences between the studies specific to CTLA-4, PD-1 combos, what are the really critical ones, in your view, that could lead to a different outcome from what we saw at MYSTIC today?
Specifically, do you see this as issues with MYSTIC were about study powering in size?
Or is there something specific with the agents and their dosing that led to this outcome, and if you're going to comment on that?
My second question, anything from MYSTIC that would impact any of your thoughts around the -227 design and, more specifically, statistical powering and -- or statistical plans?
And then finally, how are you thinking about PFS versus OS as a key endpoint as we think about the first-line lung market and I-O studies?
Giovanni Caforio - Chairman of the Board & CEO
Chris, this is Giovanni.
Let me just start, and then I'll ask Tom to give you any other comments.
I think many of the -- of course, it's very difficult to speculate on any comparison of the 2 studies because we don't know really a lot about the data that was communicated today.
With respect to the design of the study, first of all, as you mentioned, size is really important.
Second, we should remember that the studies include 2 different medicines, both in terms of the PD-1 and PD-L1 and in terms of the CTLA-4.
Dosing schedule are extremely important.
And also, as we've said already, you have to remember that -227 really is a program and gives us the ability and optionality to look at multiple combination strategies in different patient populations.
But let me ask Tom to give you more comments about that.
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
Thank you, Giovanni.
And Chris, I think, again, it's important to sort of reflect and think about these studies.
There's much about MYSTIC that we don't know.
All we've seen is the same press release that you saw this morning.
But I think just to reemphasize, first, the CTLA-4 drugs are different.
They're different drugs, and dosing schedule may be important.
We've spent a lot of time with Yervoy optimizing its dosing schedule across different tumor types, and we found that there are differences across that.
The second is the PD-1 target is different.
We are a PD-1 drug.
That's a PD-L1 drug.
That could be, when you combine with CTLA-4, potentially a difference between these trials.
And you pointed out and Giovanni emphasized the power and size are different between the 2 trials.
So I think it's very difficult to read across the 2 studies.
You did ask a specific question about -227.
And as you know, we have not disclosed our statistical plan for this study.
And again, I think that the data today certainly is one piece of the information, but I think that the ability to understand what the ultimate best way to treat patients will require more data from MYSTIC and certainly the results of both -227 and 9LA.
Operator
We'll go next to Vamil Divan with Credit Suisse.
Vamil Kishore Divan - Senior Analyst
So I guess just a couple here.
You mentioned the dosing schedule a couple times there in terms of differences here between -227 and MYSTIC.
But I was also intrigued by the filing you had with a fixed dose, every 4-week dose.
And you're, I think, relatively quiet talking -- in terms of talking about that with The Street before you submitted it.
So just can you share a little bit more about the data you have around that and your formulation and just what gets you comfortable that this fixed dose will be appropriate across all tumor types?
And then may be one, just shifting gear a little bit more to the results for the quarter.
You raised the bottom end of your guidance range on EPS, but your sales guidance looks like it's unchanged.
Can you just share some thoughts on your views on the top line and obviously the moving parts in the back-end of the year with the KEYNOTE 189 study?
What is it that's keeping you sort of not changing sales guidance?
I know you had a good quarter here, and you are raising the bottom end of the EPS guidance.
Giovanni Caforio - Chairman of the Board & CEO
Thank you.
So this is Giovanni.
Thank you.
I'll try to cover some of your points at a high level and then I'll ask Charlie to make some comments on guidance and the rest of the year and Tom and Murdo to give you some perspective on dosing.
So first of all, let me say our performance in the second quarter and actually in the first half of the year is very strong.
Commercial execution continues to be very, very strong, and trends are good across products and across geographies.
So we see good momentum.
Obviously, there is a degree of uncertainty in lung cancer, particularly in the U.S. Similarly, we are at the beginning of our launch of hepatitis C in China.
So those are trends that are a little more difficult for us to comment.
But overall, I would say we feel we are in a really good position from a commercial execution perspective.
With respect to dosing, I think that we -- as Tom was mentioning, we are working really as a priority to continue to optimize the schedule of our assets across indications, across lines of therapy, in combination.
And what you've seen with -227 is really a lot of work that went into defining that dose.
Similarly, we've been working on the 4-weekly dosing for Opdivo monotherapy.
And I'll just have Charlie first and then Tom and Murdo to give you more comments about that.
Charles A. Bancroft - Executive VP, CFO & Head of Global Business Operations
Yes.
I mean, not much to add to what Giovanni said.
We are pleased with the first half performance.
There is uncertainty, as I mentioned in my comments, regarding Opdivo as we look at the second half of the year, and we're roughly 2 weeks into our hepatitis C opportunity in China.
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
So I think your question about our fixed dose, sBLA, I think, is a good one.
And when we think about how to use these drugs, we want to think about giving doctors and patients the most flexibility and optionality in the way they use these drugs for convenience and for potential efficacy when we combine them in different settings.
So as you know, we have the 3-milligram per kilogram dose approved and the fixed dose at 240.
So the ability to have a q4-week dose might be appealing for many patients and many doctors.
And also to note, we also have in -227 the 3-week fixed dose, so that can combine better with a q3-week chemotherapy.
So I think what patients and doctors want is the ability to use our drugs in a way that's most convenient for our patients and for physicians as we put together multiple combinations.
I think that you're going to find as combination therapy continues to play a greater role as we move forward, that this kind of flexibility in dosing will be very important as we move forward.
Murdo Gordon - Executive VP & Chief Commercial Officer
Yes.
Vamil, the only thing I would add is this could be particularly helpful in parts of the market where infusion infrastructure is a little more constrained, for example, academic medical centers, large regional hospitals.
We have seen definitely some preference there for longer duration or longer interval between dosing, whereas in the community setting, the q2-week dosing schedule we've had until now has been fairly well accepted.
So that q4 will have an advantage definitely in the academic setting, definitely in the regional hospital setting.
And then we are interested, as Tom mentioned, in pursuing the most convenient dosing across indications, and that may vary depending on combinations, as Tom mentioned, as we evolve our portfolio.
Operator
We'll go next to Gregg Gilbert with Deutsche Bank.
Gregory B. Gilbert - MD and Senior Analyst
First, I was hoping, Tom, you could comment on your perspective of PD-1 or PD-L1 agent hitting on OS, after missing on PFS.
Secondly, can you share your thoughts around the company's appetite to play in the PARP space?
Pretty interesting collaboration announced earlier that could be material in the industry.
And lastly, you've begun to talk more about NASH this year.
At this point, have you met with the FDA yet to plan a pivotal study and when could that start?
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
Thanks, Gregg.
And let's break these down into 3 parts.
And I think I might start with the NASH first, and then we'll talk about PD-1 and PARP.
So as you know, nonalcoholic steatohepatitis is an important clinical disease.
And it leads to cirrhosis.
It leads to potential hepatocellular carcinoma down the road.
We're very interested in our FGF21 agent because our FGF21 agent is able to approach all 3 elements that seem to be important in NASH and the pathophysiology of NASH.
First, it approaches the metabolic arrangement that we often see in NASH in terms of fat accumulation.
Second, it has the ability to reduce the inflammation that's important in the pathophysiology of NASH.
And finally, it has anti-fibrotic impacts as well.
And so we presented Phase II data on FGF21 at EASL this year that showed that we were able to reduce hepatic fat in a patient population of people with NASH, giving us a clear signal that this is something we want to take forward into Phase III.
And we have been discussing -- to answer your question directly, we have been discussing our NASH data with regulatory authorities.
And we hope to begin Phase III trials in a program by the end of this year, depending upon timing and how we're able to accomplish our timing.
So this is an area that we definitely want to pursue.
As we mentioned many times on these calls, we're not just a cancer company.
Cardiology, fibrosis, immunoscience are very important to Bristol-Myers Squibb.
Second question about PD-1 versus PD-L1, I think that's a terrific question.
And if you go back 2 to 3 years, there were people who thought that PD-L1 drugs might turn out to be better than PD-1 drugs.
And I think now, I think, again, we have to really see where the data takes us and follow the science as we look at PD-1 drugs and PD-L1 drugs as we move forward.
And again, around your question of overall survival versus progression-free survival in terms of endpoints, as an oncologist, we always like it when we see overall survival data.
It certainly is something which can help doctors make decisions in terms of treating patients.
But as we know, with the influence that second-line and third-line therapy has made, it's increasingly difficult to be able to demonstrate overall survival.
And so for example, if you look at breast cancer, many, many breast cancer drugs now have been approved on PFS.
So I do think that PFS and OS will continue to be important endpoints and will be different in different studies as we move forward.
And finally regarding PARP, I'll mention a couple of comments from a scientific standpoint and turn it over to Charlie to offer more comments.
I've always felt that PARP was an important target in oncology.
DNA repair is clearly one of the hallmarks of tumor progression.
And it's something that -- mechanistically, the ability to combine a PARP inhibitor with an I-O agent is something, to me, is very appealing from a scientific standpoint.
And Charlie, do you want to comment on...
Charles A. Bancroft - Executive VP, CFO & Head of Global Business Operations
No.
I mean, I would just say, we think it's an interesting class and particularly it's synergistic with PD-1.
And it looks like it may have applicability in tumors like ovarian, prostate and triple negative breast, and it's something we continue to look at.
Operator
We'll go next to Tim Anderson with Bernstein.
Timothy Minton Anderson - Senior Analyst
A couple of questions.
It's not -- on -227, it's not terribly clear to me why you can't give some elements of statistical design.
It's not like there's a wealth of CTLA-4 competitors that are going to suddenly go out and change their trials.
So with that as my comment, I'm hoping you can at least talk about whether the analysis is going to hierarchical in nature.
And maybe you can reveal what the starting cut-point would be for that analysis.
And then on this first readout potentially by year-end, are you expecting that you'll have both PFS data and mature OS data at the same time?
Or could the OS piece come a lot later like it will in MYSTIC?
The reason I ask that is that MYSTIC today shows that maybe PFS is not a great measurement.
So if your OS data isn't mature, I'm wondering if there's risk to this initial readout.
Giovanni Caforio - Chairman of the Board & CEO
Tim, this is Giovanni.
First of all, I would say, we've said all along that we have optionality with our statistical plan.
We don't really see a need to make any change there.
And with respect to the time lines for the study, the primary completion, as you said, is the first quarter of next year.
We do have an opportunity for an interim on OS by the end of this year.
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
And just to add, Tim, to your question.
I think that we have not disclosed when the interim is.
We've been saying all along that we expect to have some data in the first half of 2018.
Whether that data will be PFS or OS, as Giovanni just mentioned, we have the optionality to look at both co-primary endpoints in the study, and we look forward to seeing the data.
Operator
We'll go next to Umer Raffat with Evercore ISI.
Umer Raffat - Senior MD and Fundamental Research Analyst
I'll just focus on CTLA-4 combo but outside of lung for a minute.
So perhaps starting off in CheckMate -214, the renal trial, I was curious about the EPID dose selection every 3 weeks versus the every 6 weeks deployed in -227 and if there have been any interims in that trial.
And then also on CheckMate -651 in head and neck, are the OS and PFS co-primary endpoints?
Or is there a stacked hierarchy?
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
So thanks for your question.
Let me address the renal cell question as we think about it.
So think about kidney cancer.
And kidney cancer is an interesting disease.
I can remember when I was training, the only drug that worked in kidney cancer was vinblastine, and it really barely worked at all.
And yet since then, we've seen the advent of tyrosine kinase inhibitors in kidney cancer.
And they've shown very good benefit, though not for all patients who get treated with tyrosine kinase inhibitors.
And clearly, there are patients with more severe adverse disease who don't necessarily seem to do as well with tyrosine kinase inhibitors, but they've made a huge difference in how we approach the disease.
And then we've seen the advent of I-O and immuno-oncology agents and the difference they make.
As you likely know and are alluding to, we are delighted to be able to publish our study in the Journal of Clinical Oncology, our Phase II trial looking at nivo and ipi in patients with renal cell cancer.
And as you know, the combination of nivo plus ipi had a response rate of 40% with a 2-year survival that was between 60% and 65% overall, which we think is very encouraging data and is the basis for why we've proceeded with the randomized trial -214.
Our hope is that we're going to have some data from -214 by the end of this year as we move forward.
The second part of your question was about head and neck cancer.
And again, I want to emphasize that this has been a busy week for I-O in terms of readouts of various different head and neck trials.
All we know from the pembro study is it did not meet its primary endpoint.
And we don't know much more than that in terms of details.
But what we do know and want to remind you of is that the nivolumab study in patients with head and neck cancer compared to investigator's choice chemotherapy did show a survival benefit with a 1 year survival rate of 36% versus 16% for the investigator's choice and has led to the use of single agent nivolumab as we move forward.
And as you mentioned, we do have additional data that we plan to present in head and neck cancer next year.
So CheckMate -651, as you mentioned, is a trial looking at ipi, nivo versus chemotherapy and cetuximab in patients with head and neck cancer, and we expect to have that data the first half of 2018.
And we also have a trial that will be mature in the first half of next year looking at the combination of ipi, nivo versus nivo in patients who aren't able to tolerate cisplatin and cetuximab.
As you know well, head and neck cancer patients are a uniquely comorbid group of patients with lots and lots of comorbidities that make aggressive treatments challenging.
And so we are very happy that we have trials that cover the broad range of what patients -- how patients present with head and neck cancer and what doctors see with head and neck cancer.
Operator
We'll go next to Seamus Fernandez with Leerink.
Seamus Christopher Fernandez - MD, Major Pharmaceuticals and Biotechnology
So just 2 questions.
First, Tom, can you remind us again your biomarker strategy and how you see this impacting lung?
I'm particularly interested in the application of the tumor mutation burden test as a stratifying metric in the new lung study that you guys just announced for the combination.
And then the second question is just, can you give us just a general sense of how excited you are and perhaps when we might see data from either the LAG-3 or the Flexus IDO in tumors outside of melanoma.
And if you are willing to expand a little bit, do you have plans for registrational trial starts in tumors outside of melanoma for either of those 2 assets?
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
Okay.
So let's get to the meat of the question.
So first question, Seamus, that you asked is about our biomarker strategy.
And this is an area of great interest to me, and it's an area of great importance to patients across the spectrum.
And so if you think about lung cancer, and we've said many times, it's a difficult disease to treat.
But I think the thing that I've been very impressed with in lung cancer, as a lung cancer clinician, is how this disease has evolved and how it's fragmented over the past 10 years.
If you go back 10 years, 10 years ago, we just thought of small cell and non-small-cell.
That's what you used to make your treatment decisions.
Now when a doctor is looking at a patient with lung cancer, they're thinking about EGFR, they're thinking about ALK, they're thinking about ROS1, they're thinking about PD-L1 expression.
And I think that they may soon be thinking about TMB as an important marker as well in cancer.
And so let's think what is TMB?
TMB is tumor mutational burden.
It's a measure of the amount of mutations that are present in protein-coding genes in patient samples.
And when you think about it, some people think it's important in and of itself.
Others think that TMB is really a reflection of important tumor neoantigens and that one day we might be able to look at the TMB data and define which tumor neoantigens are actually driving the immune response.
So we've been happy that we've been able to look back and use TMB in a number of settings.
As you know, the data we presented at AACR, we were able to look at TMB in patients, our -026 study.
And we were able to identify a group of patients who did very well with monotherapy.
And we will continue to look at TMB in a number of different tumor settings as -- when the data allows and when we're able to do it.
And I think one of the examples and an example to the commitment we have to TMB is in our study 9LA, which is now available on ClinicalTrials.gov.
We actually would be prospectively collecting TMB as part of the 9LA study, which is our trial of standard chemotherapy versus 2 cycles of chemotherapy with Opdivo and Yervoy.
And again, we have to file the data.
The data we have so far is early, but it certainly gives us reason to think that this could turn out to be something important in patients with cancer.
Your second question comes down to IDO and where we stand with IDO.
And as you know, this is also something very important to Bristol-Myers Squibb.
We thought enough of the IDO -- of IDO as a target that we went ahead and purchased the IDO asset from Flexus, which is now the Bristol-Myers IDO.
And we have announced that we will be moving forward with trials with the Bristol-Myers IDO as we go forward.
We think that there are some things about our IDO which could actually be differentiating and they might prove to be important.
We think we see excellent receptor occupancy.
We think we see very good suppression of kynurenine levels, suggesting that we're inhibiting the enzyme.
And this may allow Opdivo to be a more effective immunostimulatory agent.
So we're excited about where the Bristol IDO can go and in its combination with nivolumab.
But in addition to this, we also have a relationship with Incyte.
And you saw at ASCO this year, the first data with the Incyte IDO, along with Opdivo, and we saw very strong response rates in melanoma and in head and neck cancer.
And so again, eagerly awaiting to see how we get these trials going.
As we've announced, we plan to start our trials with Incyte by the end of this year, and we hope to also have our Bristol-Myers trials up and running as well during that time frame.
And finally with LAG-3.
LAG-3 is something I was extremely excited about at ASCO.
And why was that important?
I think you learn a lot by studying resistance.
And if you look at -- the most important thing about LAG-3 so far is that we looked at patients who had prior treatment with immuno-oncology agents with melanoma, and we were able to find a percentage of patients that responded to LAG-3 plus Opdivo in that setting.
And more importantly, we were able to use the biomarker LAG-3 positivity to select a group of patients that had almost a 3x higher response rate in that setting.
So we think LAG-3 is an important target.
We're going to continue to develop the biomarker, the LAG-3 biomarker, and we're going to continue to look at LAG-3 in I-O-naïve patients with melanoma as well as expanding our experience in the previously treated patients.
Giovanni Caforio - Chairman of the Board & CEO
Seamus, maybe if I can add a couple of comments there.
I think these developments that Tom articulated for you are really important for us because we've discussed this before.
And when you think about our strategic priority, advancing our early pipeline, immuno-oncology and outside of oncology is clearly a very important priority for us.
So I'm personally very pleased that we are working between now and the end of the year to start a number of registrational programs.
We mentioned FGF21 outside of oncology.
Tom mentioned LAG-3, the 2 IDO programs.
Nivolumab is another important program.
I'm very pleased that we are seeing the beginning of a number of registrational programs that are going to be really important for us as a company.
And even more broadly, I think what we've discussed today is how we are advancing a very broad program in lung cancer, which continues to expand and advance.
The second pillar is how we are moving forward with a broad number of short-term opportunities for Opdivo and Yervoy within oncology beyond lung cancer.
And the third pillar is really the new pipeline.
And I think you are seeing that we're making very, very good progress across every one of those 3 areas.

We'll go next to Andrew Baum with Citi.
Andrew Simon Baum - Global Head of Healthcare Research and MD
Three questions, please.
The first one relates to MYSTIC.
So your competitor seemed to highlight the number of trials where I-O had missed PFS and gone on to hit overall survival, and head and neck is obviously one of them for you.
You obviously have more experience with I-O than anyone else in the space.
Our concern is the examples of missed PFS but hit OS with I-O all seem to be in trials with short PFS, where patients have been through multiple lines of therapy, which look to us very different from the situation with first-line non-small-cell lung.
With that in mind, if you are facing a similar situation with -227, which I hope you won't, where you've missed PFS with the Opdivo, Yervoy combination, how confident would you be feeling about making the OS?
That's the first question.
Second, just going back to the differences between the individual molecules.
To what extent does your development plan for non-fucocylated CTLA-4 reflect the fact that you believe affect the function?
Is a critical element of the efficacy of the molecule different from your competitor?
And then finally, just on patient selection, aside from baseline tumor load, to what extent do you think their learnings in optimizing the patient population using baseline tumor load, performance status, liver mets, which may significantly skew any data you may get from a large clinical trial?
And to what extent can that be leveraged in your recruitment criteria?
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
So Andrew, thank you for your questions.
And the first question is really a hypothetical, and it really is impossible for me to be able to opine on a potential hypothetical of missing PFS or hitting PFS or missing OS and hitting OS.
And you really -- I really think we have to wait till we get more data from the MYSTIC study to really understand that.
As we've said earlier, we have PFS and OS as co-primary endpoints in -227, and we have not disclosed our final statistical plan in that setting.
Your second question regards the new formulation of the non-fucocylated CTLA-4.
I think -- one of the reasons we've looked at these 2 new CTLA-4 targets: First, we believe in the target.
We think the target is important.
The target has been shown to have a survival advantage, as I illustrated in my answer to Jami's question.
So we think that target is important.
And if we think the target's important, the question then becomes how do we optimize the therapeutic index?
How do we make CTLA-4 a better molecule -- an even better molecule than it is?
And there's 2 main approaches.
With the CytomX approach, the thought is that the Probody technology will allow a differential exposure of tumors to CTLA-4, allowing us to enhance the immune response within the tumor itself and possibly not see the same degree of side effect profile that you could see with immune side effects in other areas.
So that's the thought behind the new formula -- behind the CytomX approach.
With the new formulation, there's a possibility that there could be increased potency of the drug that could actually allow us to have more effectiveness in that setting.
And again, very early, we just started.
As we announced at the last earnings call, we just started trials with the non-fucocylated CTLA-4.
And so we're going to have to see how that evolves.
And your third question, Andrew, is around the concept of patient selection.
And I think you've hit a very important point is that as we look at these cancer types, and as I mentioned this about lung cancer earlier, we are seeing increased fragmentation in the patient populations.
And we're seeing that biomarker selection is becoming increasingly important as we look at patient populations.
And lung cancer, for example, is not just one disease.
It's many diseases, defined by EGFR and ALK and ROS and possibly tumor mutational burden and PD-L1 positivity.
So I think as we go forward, attention to patient selection and attention to thinking are we treating the right patients is something that we take very seriously in our tumor design -- in our trial design.
It's one of the reasons, as Charlie mentioned earlier, we're continuing to up-invest in R&D and up-invest in translational medicine because we think it's important for us to prospectively be selecting the correct patients.
Operator
We'll go next to Steve Scala with Cowen.
Stephen Michael Scala - MD and Senior Research Analyst
I have a couple questions.
On CheckMate -227, is the interim in 2017 on PFS or OS?
I think Giovanni said OS.
I had thought it was also PFS or only PFS, so please clarify.
And related to that, why would it make sense to do the interim look in Q4 as opposed to Q3 since the conclusion is in January?
Would you agree Q4 doesn't provide much benefit in terms of timing?
So that's the first question.
Second question is regarding CheckMate -568.
I think Bristol is saying there is a possible update in 2017.
What does whether there is an update or not depend on?
John E. Elicker - SVP of Corporate Affairs and IR
Steve, it's John.
Real quick on the interim analysis.
We have said all along that, like in all of our trials, we've built in optionality, which we have in -227.
In terms of timing, everything is event driven.
So we've never committed to January, even though that may be what's on ClinicalTrials.gov.
And we've said sometime in the first part of 2018 is when the primary endpoint should read out.
So both the interim and the primary analysis are event driven and so obviously time flexible.
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
So Steve, regarding your question on -568, so I'd just give you a little bit of color behind -568 and sort of how it got to the place where it is.
So -568 was designed as a practice-enabling study of Opdivo and Yervoy.
We initially designed -568 to be about a 160-, 170-patient study initially.
And with more experience, we decided to increase that size to 300 patients.
And then last year, we decided to actually add a randomized portion to -568, looking at this question of 2 cycles of chemotherapy, followed by Opdivo and Yervoy.
And that will be an all-comers trial.
Now after discussions with the agency, we've actually decided to make that a separate Phase III trial.
So that's the trial that's now called 9LA.
And so that trial will get going.
We hope the first patients will enter that trial -- we have a safety lead-in right now, which to the best of our ability seems to be going well with the 2 cycles, followed by Opdivo, Yervoy.
And so we hope to begin accruals for that trial in September of this year if all goes according to plan.
As of now, we have not yet decided upon our presentation strategy for -568, but we look forward to sharing that with you when we have.
Operator
We'll go next to David Risinger with Morgan Stanley.
David Reed Risinger - MD in Equity Research and United States Pharmaceuticals Analyst
I have 3 questions.
The first is, with respect to U.S. Opdivo in the second quarter, could you just provide the percentage of sales in different cancer types in the second quarter?
Second, with respect to your expectation for Yervoy combo Phase III kidney cancer results by the end of the year, could you just help reconcile that with ClinicalTrials.gov?
ClinicalTrials.gov indicates the primary completion for that trial's on September 30, 2019.
So it makes me wonder why look at any Bristol-Myers dates on ClinicalTrials.gov.
And then finally, with respect to your Flexus IDO, when do you expect to present Phase I data on that later this year?
Giovanni Caforio - Chairman of the Board & CEO
Okay.
David, let me ask Murdo to start and give you some data on Q2 U.S.
Murdo Gordon - Executive VP & Chief Commercial Officer
Yes.
David, for Q2 U.S., about 50% to 55% of our sales are in non-small cell lung cancer for Opdivo.
And renal cell carcinoma is between 15% and 20%; and then the other big one for us is melanoma, 10% to 15%.
There are, obviously other tumors with bladder, head and neck, and others.
But those are the 3 big ones, and that's the split.
Giovanni Caforio - Chairman of the Board & CEO
For the -214, by the end of this year, that is an interim analysis.
You may be referring to the final analysis.
And let me ask Tom to give you an answer to your question -- to your third question, David.
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
And your third question regarding the Flexus IDO, we hope to have data, in fact, I'm pretty sure we will have data for the SITC meeting this fall.
Operator
We'll go next to Geoff Meacham with Barclays.
Geoffrey Christopher Meacham - MD and Senior Research Analyst
So Tom, another one on CTLA-4.
Obviously, data-dependent, but if -227 looks underwhelming, would the strategy be to explore triple combos in lung?
I'm just thinking with all the assets and novel mechanisms you guys have in-house, whether you view CTLA-4 as more foundational.
And then for Murdo, in the quarter, can you give us some perspective on second-line lung share and new start trends?
Just trying to think whether through -- whether Keytruda is slowing starts?
And then looking forward, would you expect any formal reimbursement limitations on sequential I-O therapies in lung?
Giovanni Caforio - Chairman of the Board & CEO
Geoff, why don't we just start with Murdo to give you some perspective on your 2 more commercial questions, and then Tom will address your CTLA-4 question.
Murdo Gordon - Executive VP & Chief Commercial Officer
Okay.
Thanks, Geoff.
In second-line lung cancer, our shares have actually been very stable.
So we run around 40% share of second-line lung cancer, and that market volume has held up quite well so far because the impact of pembro usage in first line has not yet been felt in a reduction of eligible second-line patients.
That will change as we get closer to the end of the year where the shares in second-line lung should hold, but the addressable eligible population of second-line I-O-naive patients will start to shrink.
And obviously, next year, there'll be a smaller pool as well.
I will say, our teams have done extremely well in establishing this holding of share despite 2 competitors in the second-line setting.
And ex U.S., we've done very well given the lead that we've got in second line in many markets due to fast reimbursements.
So the emergence of our lung cancer business ex U.S. is also driving some nice growth.
And then outside of lung cancer, our shares are very good in regimen in melanoma.
In head and neck, we've seen some recent acceleration.
In renal cell, we've held up well.
Bladder, we're emerging.
And then actually, the broad usage in other areas where NCCN has updated, like Tom mentioned, in mesothelioma is also helping to drive growth outside of lung.
So we feel good about that.
In terms of reimbursement limitations, really, in the U.S., we have seen very good prior authorization approvals in the mid- to high-90% range even in combination settings.
And of course, in melanoma, it's really the market where we see the most amount of combination use today.
Now we are obviously tracking the U.S. environment very closely.
And we are, I think, in a very good competitive position should there be further restriction or barriers to combination reimbursement as you see sequential lines of therapy evolve, given that we have multiple targets and multiple combinations to use in those settings.
Giovanni Caforio - Chairman of the Board & CEO
Tom?
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
So Geoff, thank you for your question.
And this is an area of great interest to me.
So the first thing is I can't really think about a hypothetical of -227 in MYSTIC.
So I think it's really not helpful to think about hypotheticals.
But I do think it's important to think about triples.
And something I've been interested in for quite sometime is this idea that I really think that to begin to think about how we're going to be driving prolonged survivals in cancers, we've really only begun to scratch the surface in terms of thinking how to use these drugs.
And I do think that triple therapy, quadruple therapy down the road makes sense.
Just think about lymphoma.
When you think about the fact that we cure lymphoma now with 5 drugs.
We've made a huge difference for patients with lymphoma in that setting.
And it's entirely possible that ultimately the way we approach lung cancer, other cold tumors and even melanoma were with multiple drugs.
So for example, we have announced that we have begun some dose finding studies and early trials with IDO inhibitor plus Opdivo and Yervoy, looking at that together to try to learn, could there be a signal with that triple in melanoma.
And we also have plans to look at a LAG-3 with IDO and Opdivo as well.
And so we are committed to multiple-drug combinations.
Of course, the difficult thing is as you begin to put together multiple-drug combinations, trying to determine the relative impact of the different components becomes very challenging and requires a tremendous amount of creativity and innovation in clinical trial design.
Operator
We'll go next to Marc Goodman with UBS.
Marc Harold Goodman - MD and United States Healthcare Analyst
So first, Murdo, for Opdivo.
Can you give us a sense of where the OUS sales are coming from, just like you did with the U.S.?
Second, on Eliquis, where is the market share now for the cardiologist specialists?
Just give us a sense there.
And then third quarter DAKLINZA, can you confirm there were no sales in the second quarter?
And then -- for China?
And can you give us a sense of what kind of ramp should we be expecting in China?
Obviously, hep C, we've seen pretty amazing ramps when these products launched.
So give us a sense of how we should expect sales for China.
Murdo Gordon - Executive VP & Chief Commercial Officer
Sure.
Thanks, Marc.
Ex U.S., we've seen very nice launch progression in Japan, France, Germany, Italy, Spain.
We are very early in our launch trajectories in Canada.
We're hopeful that we'll be launching soon in Australia.
In the U.K., we've launched in our regimen setting in melanoma, and it's going extremely well.
So our business is really broad, and we've got over 20 markets ex U.S. now reimbursed either fully in lung, renal and melanoma or at least lung and melanoma.
And we're working now on our head and neck and bladder indications to be able to secure reimbursement there.
So I think our position in Europe, in particular, is very, very strong because of the timing advantage we've secured with indications there and with the rapid uptake that we've been able to achieve.
So OUS, I feel very good about, and the teams have done extremely well across medical and commercial to launch.
With respect to Eliquis, we are sitting with very strong shares now.
We are at roughly 53% Eliquis NBRx share about -- sorry, TRx share, and we're leading.
And we've got large shares in NBRx, leading that just a few more points.
So we're growing very well in Eliquis.
And of course, there's still a lot of warfarin used in total prescriptions in the U.S., with about 47% of the market still in warfarin and in NBRx.
That's down now to roughly 30%, 29%, if I remember.
So we still see a lot of headroom for growth on Eliquis, but very, very good share trends there and leading in our categories in BTE and atrial fibrillation.
And with respect to DAKLINZA in China, we did not book any sales in the second quarter.
We have started to book sales this quarter.
The uptake curve in China with the duo of DAKLINZA and Sunvepra is a very difficult thing to predict.
We are in the process of securing some reimbursement now in 3 main provinces in China.
We are currently selling primarily in the private-pay sector.
So more to report on that next quarter.
But obviously, we're very excited about the opportunity being first in the market and being able to help a very large unmet need in a very large patient population in China.
Operator
We'll go to Tony Butler with Guggenheim.
Charles Anthony Butler - MD and Senior Equity Analyst
Two questions, Tom, for you.
One, if I may go back to FGF21 and NASH in Phase III.
And the question is, could you share the design, if there is a clinical endpoint for the Phase III program?
Or is it simply looking at tissue histology, following sort of end of trial biopsy?
That's one.
And then second, back to MYSTIC and -227.
Is there -- I understand dose and schedule and a lot of the comments that you've made.
But are there perhaps other characteristics of these antibodies that may be substantially different, which could actually allow for some clinical differentiation, for example, one being IgG1 versus IgG2?
'Don't know if that really matters, but it could.
Clearly, you've made some comments that glycosylation could affect binding characteristics for ipilimumab.
I'm just looking for something more than simply dose and scheduling, if you think that might be useful.
Thomas J. Lynch - EVP of R&D and Chief Scientific Officer
Tony, thank you for your question.
First on FGF21 is the data on the -- or the designs of those trials will be available on ClinicalTrials.gov.
It's something we're discussing with the regulatory agencies now.
The second question is a good one, and many people have suggested that IgG1 versus IgG2 could explain potential differences.
They are different drugs, so there does exist a possibility that there could be differences.
But again, our job is trying to define the best way to use CTLA-4-based Yervoy and our agents.
And I really don't -- I don't have a real thought as to how important these other factors could be.
I mean, there's certainly some science that suggests that there could be some differences.
But again -- it's, again, very early in the process of understanding how they work.
Giovanni Caforio - Chairman of the Board & CEO
Thank you, Tom.
Thanks, Tony.
Again, we just completed another strong quarter.
I am very pleased with execution across the company.
As you've seen, we delivered strong sales performance, and we are continuing to make good progress from a clinical perspective and from a regulatory perspective.
Looking ahead, as I said at the beginning, I see tremendous opportunity for us to continue to grow, and I am very confident that we're well positioned for the long term.
So thanks, everyone, and have a good day.
