We also published a financial presentation which Keith will reference during his remarks. The presentation is also available on our website under Events and Presentations in the Investor Relations section of our website. I will now turn the call over to Bonnie Anderson, Veracyte's Chairman and CEO.
Thank you, Angie, and thanks, everyone, for joining us today for our second quarter 2019 earnings call. We had another terrific quarter in which we continued our strong momentum and delivered exceptional results across the business. We generated record revenue of $30.1 million, an increase of 32%, and genomic test volume of 9,663 tests, an increase of 26% over the second quarter of last year. In tandem with this growth, we improved our net cash used in operating activities to $2.5 million, an improvement of 21% over prior year. Based on these results, which exceeded our expectations and our increased visibility into the rest of the year, we are raising our full-year 2019 revenue guidance to a range of $119 million-$122 million.
We are also improving our outlook for net cash used in operating activities to a range of $2 million-$4 million for the full year and remain on track to reach operating cash flow breakeven before the end of 2019. I will now provide updates on the key metrics we are using to measure our success in 2019. The first is revenue growth. Starting with pulmonology, and specifically with idiopathic pulmonary fibrosis or IPF, Medicare coverage for Envisia genomic classifier went into effect in the second quarter. We began to ramp commercial expansion. We increased Envisia test volume as well as the number of institutions ordering the test by more than 100% sequentially from the first quarter of 2019 to 130 tests and 76 sites, respectively. Envisia test volume represented approximately 15% of our total pulmonary product volume in the quarter.
We remain on track to report Envisia test volume of 500 to 1,000 tests for the year. In lung cancer, we achieved over $1 million in revenue for our Percepta Classifier in the second quarter, which is nearly 160% increase over the prior year's quarter and a significant achievement. This pairs with other exciting news in the quarter, the commercial launch of our Percepta Genomic Sequencing Classifier, or GSC, which was developed using our RNA whole-transcriptome sequencing platform. In addition to down-classifying patients with inconclusive bronchoscopies to low risk so they may avoid unnecessary invasive procedures with a slightly higher sensitivity than the original test, this next-generation test up-classifies patients to high risk to help guide next intervention steps, providing expanded clinical utility that aligns with current guideline recommendations. Adoption of our Percepta Classifier is going really well.
Test volume in the second quarter increased 142% from the prior year's quarter to 744 reported results, and in only six weeks after its launch, we have already converted over 80% of our Percepta orders to the Percepta GSC. Biopharma services revenue of $3.5 million in the quarter was primarily the result of achieving key milestones related to the launch of the Percepta GSC through our collaboration with J&J. Our Afirma business also delivered a strong quarter, where a wealth of positive clinical performance data helped further drive robust adoption of the Afirma Genomic Sequencing Classifier. The Afirma GSC volume was 8,789 tests for the second quarter and 19% increase over last year. We also experienced significant growth year-over-year in Xpression Atlas orders for thyroid cases deemed suspicious for cancer by the Afirma GSC.
This increase was driven by physicians' growing interest in using gene alteration data to tailor surgery and treatment decisions for their patients, using information we can provide from the same minimally invasive fine needle aspiration sample, and at the same time as diagnosis. Our continued strong revenue growth reinforces the power of our integrated sales strategy, through which our sales reps are leveraging common stakeholder relationships to drive adoption of multiple products in institutional accounts, rather than us building a dedicated team for each product. For example, from the first to the second quarter of this year, the number of sites using our two lung products, the Percepta and Envisia Classifiers, more than doubled. The number of sites using all three products nearly tripled. We believe this efficient, highly effective approach is key to achieving long-term profitable growth.
I'll now turn to our second metric of success, evidence development, where we made meaningful progress during the second quarter. This includes the third recent publication of an independent clinical utility study showing that use of the next generation of Afirma GSC significantly reduced the number of surgeries among patients with indeterminate thyroid nodules. In this case, by two-thirds at the Ohio State University, compared to the original Afirma test. Additionally, data presented at ASCO showed the potential of the Afirma Xpression Atlas to guide targeted treatment selection for patients with medullary thyroid cancer, or MTC, a rare but aggressive form of thyroid cancer from the same fine needle aspiration sample used in diagnosis. In the MTC cases, the Afirma XA was highly effective in identifying gene mutations that are the focus of new targeted therapies under development.
Positive clinical trial data for two treatments targeting the RET fusions in MTC were also presented at ASCO. The role of Afirma testing in helping physicians overcome a range of challenges in the diagnosis and treatment of thyroid cancer also appears on the June cover of the highly regarded journal, Cancer Cytopathology, which is a publication of the American Cancer Society. In lung cancer, we unveiled clinical validation data for the Percepta GSC during the American Thoracic Society meeting in May, showing the next generation's test ability to down classify lung nodule patients to low risk of cancer while up classifying patients to high risk with strong performance results that are consistent with guideline recommendations for next steps. Finally, the adoption of the Envisia Classifier is being fueled by the publication of positive clinical validation and clinical utility data in The Lancet Respiratory Medicine in early April.
The findings demonstrate that the test helps physicians distinguish idiopathic pulmonary fibrosis, or IPF, from other interstitial lung diseases without the need for surgery, and that when paired with high-resolution CT results and patient clinical history, the test provided physicians with a higher level of confidence in making an IPF diagnosis. The extensive, rigorous clinical evidence that we continue to build to support our test validity and utility is driving our success across all three clinical indications and is further establishing our scientific and medical leadership. Our third metric of success is pipeline advancement, where we also made solid progress during the quarter.
With the launch of the Percepta GSC on our RNA whole-transcriptome sequencing platform, we are now in a position to advance our pipeline to inform treatment decisions concurrent with diagnosis in lung cancer, addressing additional questions across the clinical care continuum, just as we have done with the Afirma Xpression Atlas in thyroid cancer. We are also advancing our pipeline to address unmet needs earlier in the clinical care continuum in the fight against lung cancer. Specifically, we are excited about our progress in developing the first genomic test to detect lung cancer in non-invasive samples collected from the nose. Our nasal swab test will utilize the same proven field of injury science that powers our Percepta GSC, whereby lung cancer can be detected in current and former smokers by evaluating genomic changes in the epithelial cells lining the respiratory system.
We believe our nasal swab test that is in development has the potential to significantly improve the early detection of lung cancer, which in 2018 was estimated to kill approximately 1.8 million people globally. Our development efforts are facilitated by our collaboration with J&J through the combination of our robust biorepository of patient-consented, well-curated clinical cohorts, as well as their medical and clinical expertise in the early detection of lung cancer. We look forward to sharing early data for our nasal swab test, along with our plans for positioning the test in the clinical pathway of care before the end of this year. Our fourth measure of success is financial discipline. Here, too, our team has continued to excel. Our net cash used in operating activities for the second quarter of 2019 was $2.5 million, a 21% improvement over the second quarter of last year.
Through our continued strategic investment in activities that fuel the business, along with our careful spending, we remain on track to achieve operating cash flow breakeven before the end of this year, an accomplishment that very few in the genomic diagnostics field have attained. More importantly, our goal is to achieve long-term profitable growth. Finally, we continue to strengthen our leadership team, and we're thrilled to name Keith Kennedy as our Chief Operating Officer in addition to his current role as Chief Financial Officer. Together with Dr. Giulia Kennedy, our Chief Scientific and Medical Officer, and John Hanna, our Chief Commercial Officer, we have a top-tier executive team that is prepared to lead us in the next phase of growth. We also announced two key hires during the second quarter. First, Dr. Sangeeta Bhorade joined Veracyte as our new Medical Director for Pulmonology.
She was previously a professor of medicine and the medical director for the lung transplant program at Northwestern University's Feinberg School of Medicine. Also, Dr. Freddie Bowie joined us as vice president of corporate and business development, bringing significant experience, most recently at Foundation Medicine. Lastly, I'm thrilled that in June, Veracyte was awarded a San Francisco Bay Area Top Workplace 2019 honor for the sixth consecutive year. This recognition reflects the dedication of and contributions by our more than 300 employees who come to work each and every day with a focus on making a real difference in the lives of patients and are a key driver of our success. I will now turn the call over to Keith to go over our financial results for the second quarter of 2019.
Thank you, Bonnie. As Angie mentioned earlier, our second quarter 2019 financial presentation is available under Events and Presentations in the Investor Relations section of our website. Turning to page three of our financial presentation, our performance against six financial Key Performance Indicators, or KPIs, for the second quarter of 2019, as compared with the prior year's quarter, including select highlights for each metric at the bottom of the page, are as follows. Revenue of $30.1 million, increased 32%. Excluding $3.5 million of biopharmaceutical services, revenue of $26.7 million, increased 20%. Genomic volume of 9,663 reported tests, increased 26%. Gross margin of 71%, increased 700 basis points. Excluding biopharma services, gross margins increased 400 basis points from 63% to 67%. Operating expenses, excluding cost of revenue, increased 20%. Net loss of $2.5 million, improved 60%. Net cash used in operating activities of $2.5 million, improved 21%.
At June 30th, we had cash and cash equivalents of $193 million. Turning to page four of the presentation, our performance against these six KPIs for the year-to-date period ended June 30th of 2019, compared to the same prior year period, show strong comparable performance. The next six pages outline the sequential and year-over-year results underlying each of the six financial KPIs. A few observations. As illustrated by the revenue and genomic volume trends on slides five and six, we continue to see positive momentum across the business. Our lung portfolio represented approximately 875 tests or 9% of our genomic volume this quarter. Turning to page 12 and our 2019 guidance, as Bonnie stated earlier in her remarks, we are increasing our revenue guidance to a range of $119 million-$122 million. At the midpoint of the range, this represents a 31% increase over last year.
We are tightening the range of our previous guidance for annual net cash used in operating activities to $2 million-$4 million. At the midpoint of the range, this represents a 78% improvement over last year. Generating positive operating cash flow remains a key goal for us. We expect to achieve operating cash flow breakeven before the end of this year. Our loss from operations in the second quarter was $3.1 million, which included $3.5 million of depreciation, amortization, and stock-based compensation expense. To add some color on our outlook for 2019, we expect the following. Our revenue and operating cash flow guidance includes $10 million in service revenue, $9 million from J&J and $1 million from Loxo Oncology. We expect gross margins, excluding the impact of biopharma services revenue, to be within the 65%-67% range and up from our previous expectations of 64%-66%.
We expect our average quarterly spend for sales and marketing to stay within a $1 million band around the average quarterly spend of $13 million. Our average quarterly spend for our combined G&A and R&D spend to stay within a $1 million band around the combined average quarterly spend of $10.5 million. I will now turn the call back over to Bonnie.
Thanks, Keith. In summary, we had a terrific quarter in which we continued to execute, driving revenue and genomic test volume growth across the business. Our first-to-market Medicare-covered genomic classifiers and biopharma collaborations are contributing to strong revenue growth, and our multi-product sales strategy is enabling us to drive this growth cost effectively. We also advanced our pipeline, launching our next-generation Percepta classifier in lung cancer while progressing our nasal swab program for early lung cancer detection. Our world-class scientific capability and technology are positioning us to answer additional clinical questions along the clinical care continuum, and our recent capital raise gives us strategic flexibility as we make the promise of precision medicine a reality for patients. I would now like to ask the operator to open the call up for questions.
Ladies and gentlemen, if you have a question at this time, please press the star and the number 1 key on your touchtone telephone. If your question has been answered or you wish to remove yourself from the queue, please press the hash key. Your first question comes from Sung Ji Nam from BTIG. Your line is open.
Sung Ji?
Oh, sorry, I was on mute. I apologize. Thanks for taking the questions. Maybe starting out with Envisia, love to hear any feedback you're getting, seeing a nice growth there initially. As you look at the number of sites using both Envisia, what's the overlap between the sites that are using both tests versus using each separately? Also curious about what your strategy is in terms of selecting sites for Envisia, given that Are you targeting kind of the major IPF centers there, or are you taking more of a broader kind of community type of settings that might realize the value proposition more for the test?
Well, Sung Ji, thanks for joining us, thanks for that very rich question of multiple levers. We'll try to work through all those. Envisia is definitely getting off the ground very well. This test addresses such a big unmet need because other than surgery, when HRCT is not confident for diagnosis, recognizing that UIP pattern, which really only happens in general 25% to 30% of the time, there is no alternative. Bringing this test to market, we knew there would be high demand and high unmet need, we're very pleased to see the level of interest. We also always anticipated that we would get sort of that extra leverage in pulmonology.
In fact, if we go back to the strategic rationale of doing our Allegro acquisition when we did in 2014, it was partially the result of the fact that our next pipeline product to bring to market was also in pulmonology. We've always seen that that synergy would be there. Nevertheless, as you also point to, there are different, often, clinical specialists that focus on one disease area versus the other, and so we recognize that as well. I have to point to, in fact, I'm going to ask John Hanna, who's here in the room with us today, our Chief Commercial Officer, to speak briefly to this at the field level.
We've actually designed the structure of our sales team to include specialists and levels of people that can address these both collectively unifying the pulmonology call point, but also at a specialist level as it addresses unmet needs that are slightly different and perhaps different specialists that treat IPF-ILD patients versus lung cancer. John, do you want to add a little bit of color to that?
Yeah, I'm happy to. Thanks so much, Bonnie, and thanks for the question. We're seeing a tremendous amount of synergy at the field level inside these pulmonary practices where they're performing lung cancer diagnostic bronchoscopies, but their colleagues are also treating and managing interstitial lung disease in the practices. So once we're within the account, we have a relationship and our specialists can expand the business beyond lung cancer into ILD. It becomes a really effective way to grow. As Bonnie shared, we grew by over 100% quarter-over-quarter in the Envisia volume and a lot of that is due to the ease of us kind of getting into those practices and then expanding the use of our product portfolio across that pulmonary practice once we're there.
Great. Thank you so much.
Thank you, John. Thank you.
Just one follow-up. It's nice to see that Veracyte continues to focus on operational and financial discipline. Given the recent strengthening of the balance sheet, we'd love to hear your thoughts on kind of what the cash deployment strategies or priorities are over the next, I guess, few years. Thank you.
Yeah. I think as a $1.4 billion company, we have the right level of cash on our balance sheet for the market cap of the company. Things can always come up and you want to have the strength there, we certainly used a portion of it to pay down the debt essentially, so we're debt-free. That's all good. I think also, we're in a really great position having executed so well across these multiple clinical indications and with a strategy that is working very well, sort of not just in gaining leverage at the field level and how we're structuring and now executing on that, but also the leverage of our scientific approach, the building up of clinical cohorts, all these things that can be repeated. We think we're in a great position if strategic options would come along.
We now have the cash to take advantage of that as well. It just positions us, I think, as it should in the marketplace with lots of opportunities and options that we can act on.
Great. Thank you so much.
Thank you very much for joining.
Your next question comes from Puneet Souda from SVB Leerink. Your line is open.
Yeah. Hi, guys. Hi, Bonnie. Congrats on the quarter. First, and obviously to Keith as well for having the additional new role. Now I get to ask him maybe twice the questions.
I like that.
If I could ask Bonnie just on in terms of the biopharma collaborations, that's been a positive driver for you, and then obviously included in the guide for the year as well. I wanted to get a sense of potential leveraging of these biorepositories of lung and thyroid into more broader collaborations and sort of what efforts are you doing there and how should we think about that opportunity longer term for you?
Right. Well, it's an excellent question. I think as we, maybe unlike others in the space, we did not expand into biopharma services specifically to drive a new segment of the business unto itself. We were very much looking at taking the indications that we're in and leveraging our assets, our capability, our position in clinical diagnostic testing and leverage that into relationships with biopharma that would bring additional value. That value can be created, as you can see, in many different ways. In our Loxo collaboration, it's being driven by the fact that we are a clear market leader in the thyroid cancer testing space.
The mere volume of the doctors we touch every day, the samples we bring in through our laboratory, coupled with the fact that every sample we run is run on our RNA whole-transcriptome sequencing platform, allows us to gain more knowledge around those thyroid cancer samples and thyroid cancer in general than anyone else out there. Their interest in targeted therapies as it relates to these rare variants that often would be more difficult to find, we were a great stopping point given the mere volume of our commercial sample repository. In the case of J&J, it was really tapping our joint interest in tackling the issue of people dying with lung cancer. Both companies focused on early detection.
J&J looking at early detection and interventive therapies that can impact disease and the strong collaboration that we built through the acquisition of course, and then onwards into the work we're doing with them today around their work in field of injury and how we can advance less invasive sample collection tools to address broader and broader and broader market opportunities over time. I think the collaborations can take on different shapes and sizes, but it all comes back to us building something here at Veracyte that is another value creation lever for the business. We believe that Envisia is another opportunity as we go forward. It's very early with Envisia because we're just now getting ourselves established in the marketplace.
There's no question that there's going to be many stakeholders looking to improve the diagnosis of IPF, whether it be in early drug trials, in patient enrollment in trials, or just better management of patients and prescriptions of therapy for those cases. We are really the only company and very nicely positioned to have an impact there. I think as we go forward with Envisia over the next 12, 24, 36 months, we will be gaining a lot of credibility as a market leader in really changing the whole diagnostic paradigm for this disease in these patients. We hope we can help get them diagnosed earlier, on treatments earlier, and help to advance better therapies to market, and it'll all be win-win for everybody.
Great. Thanks for that. Maybe a broader question now. You have three products on the market. If you could share your thoughts about the product expansion and how you're thinking about that and maybe how potentially Veracyte could look potentially like three to five years from now, anything you can share there would be helpful.
Yeah. Thank you, Puneet, for the question. I appreciate it. I think that our strategy, we're really only an 11-year-old company. We were very focused for many of those years around building out a base of products. Now with three clinical classifiers, we've actually brought five of those products to market because two of them are already second-generation tests, but building a stronghold at the point of diagnosis of disease. We think that entry point into the marketplace is very attractive because it allows us to be working with doctors and health systems and specialists alike to improve on the diagnosis of disease, and then with technology that we're tapping, be able to answer other clinical questions, downstream clinical questions, at the same time of diagnosis.
The fact that we have built all of our clinical biorepositories and all of our knowledge around the broad-based disease at the stage of diagnosis, we've got patients with the disease, without the disease, suspected of having the disease, early disease, late disease, metastatic disease, you name it. That's all in our arsenal. Combining that with the richest whole RNA transcriptome data and having the capability scientifically in machine learning and all of that pipeline development that we've had on the data side, we've been able to show that entering in the thyroid space, in the diagnostic space, has allowed us to answer downstream questions at the same time of diagnosis that is now impacting surgery decisions and treatment decisions for these patients. Thyroid cancer is not the poster child for targeted therapy and early decisions around treatment, but other indications that we're in are.
We believe this strategy is really powerful, and the tools that we're using allow us to do that. As we expand in lung cancer with our second-generation Percepta test, our plans there, as you know, are not only to move earlier with earlier detection, but also help inform aggressiveness of disease and stage and treatment decisions as well. This is all laid out. This is not new, but it's all laid out in our value chain pipeline story that we often talk about. With Envisia, I think the minute we brought the product to market to make a diagnostic decision, physicians immediately ask us, can we help them answer the prognostic question as well? Can we discern which patients are likely to progress faster than others? Because that will guide interventions and aggressiveness of interventions.
All of these decisions are now really within our reach because we are sitting on a very comprehensive technology. We've built a lot of depth scientifically across many of the technology disciplines, and we have a proven track record and a playbook to follow as we go about doing that. I think you'll see a lot of these tests advance, and as you do, you'll see us move up and down the clinical care continuum and potentially change the timing of and the way that these kind of decisions are answered over the next 3 years-5 years, I think we'll be a very different company.
Okay. That's very helpful, Bonnie. Thank you.
Thank you.
Your next question comes from Brian Weinstein from William Blair. Your line is open.
Hey, guys. Good afternoon. Thanks for taking the questions. Just to start out with something on pricing, can you just give some directional insight into your expectation for recognized revenue per test by product and how you expect that to trend through this year and then also kind of longer term, just how those reimbursement or how the pricing is going to trend up and how we should be thinking about the pacing of that for Envisia and Percepta, if there's any kind of new thoughts on that as that continues to grow.
Great.
Absolutely. Thanks for joining and asking the question. Keith?
Yep. Thank you, Brian. As I talked about last quarter, look at the revenue rate per reported test just as a high level. On Afirma, our underlying guidance implies $2,700 revenue per reported test and $1,300 for each Envisia and Percepta. Those are plus or minus, but those are round numbers that get you to the midpoint of that range. I would expect that obviously Afirma, we've completed the journey on the managed care side. We still have, obviously, last quarter, we had TRICARE that we added. We continue to add things, but as you're already got 270 million covered lives, it doesn't move the needle as much when you add three or four plans. We are continuing to make progress on Afirma. Percepta and Envisia, we're going through the journey there.
We got coverage or effective coverage, as Bonnie mentioned, on Envisia for Medicare in April 1st. We've had coverage for Percepta, we're covered on all three products on Medicare. Those commercial journeys will happen over the next couple of years.
Yeah
as we develop clinical evidence and adoption at the facilities and physician level.
Yeah, we all have always believed that the evidence will drive guideline inclusion. Guideline inclusion is the biggest lever at driving the rest of the commercial payer coverage. We're in a different position with the two lung programs, given that those patients are roughly half Medicare. There's a lower volume distributed amongst all of the commercial payers. The timing of when we actually lean in on a given payer to request and work with them on coverage, you just want to make sure you have enough members using the test in those regions before you approach them, because you don't want them to reach out to their provider base and not have more than one doctor aware of the test. When it's early, that's always a little challenge. I think we are on track to continue.
We continue, as we have this quarter, to proliferate incredible evidence. We continue to get our evidence published in top-tier journals, and that will continue. I would expect over the course of the next 12 to 24 months, we will begin to move the needle meaningfully in the coverage of Percepta and Envisia at the commercial level, and that will start to march that average reimbursement price up the ladder. Our reimbursement for Medicare Envisia is a little bit higher than where the other products are. I think we've said publicly that's sort of at the high end of that $3,000-$4,000 range we had given. Ultimately, as these tests all reach their peak in reimbursement, we'll be in a terrific position of expanded margins and a great financial story as a result.
Brian, as you're thinking through this, we have done a really nice job on the cost of revenue side. Our cost of revenue for these tests have come down to around $700, and that was $800, close to $900 in the not-too-distant past. When you're thinking about $1,300 in revenue for these new products, there's going to be this period here where we're going on that commercial journey as we get up to the Medicare rate of $3,000 to $4,000 for these tests, where we're going to spend more on OpEx than we are in total net profitability like we have in Afirma. We do believe that'll be a defined period of time, and we'll talk more and more about that as we move through the quarters and into next year's guidance.
Okay, great. That was a great detailed response. Thank you for that. I don't think that you specifically said this, but kind of backing into everything else that you kind of talked about, there's no change to the expectation for the year of genomic testing volume growth of 20%-25%, correct?
That's right.
That's right.
That should imply somewhere between 39,000 to 40,000 tests. We have two less days in the next quarter than we had this quarter. That's probably about 300 tests or about 4% on a sequential quarter basis if you're looking on a days basis. We're looking at around 10,000 to 10,500 tests a quarter, sort of average the rest of the year.
Okay, great. Last one for me. With where you guys are in your sales force right now, do you think that there's any need to expand the sales force in any way over the next kind of 6-12 months? Are you guys happy with where things are today? Thank you.
Yeah. Thanks for the question. Brian, as we've always said, we have a model that we will continue to expand our sales team. What we're doing is expanding the sales team in cadence with how we want to drive revenue growth, volume growth, test volume growth, which will drive revenue growth with a little bit of tailwind. Doing that at a pace where we can keep the operational spend in check. That's actually the model and the recipe we're following to get to the positive results on cash flow. We think it works very well. John actually has a very detailed model, and the hiring is done at particular times in the year.
We know it takes 4-6 months to get these reps up to speed, and we always build that in as we're building the hiring plan in advance of delivering the future growth. It's a pretty honed model, and John's done a terrific job of leading all that. Thanks for the questions.
Your next question comes from Steve Unger from Needham. Your line is open.
Great. Thanks. Hi, everybody.
Hi, Steve. Thanks for joining us today for your, I think, first call.
Thank you. Just to start off, I was just curious if you could give us a little bit more color on the ordering trends for Xpression Atlas. It sounded like you're starting to see that populate most or even the majority of Afirma ordering. Then could you just give us some color as to, with the new Percepta GSC, how would that product inform treatment?
Yes, very good question. I'll start with Xpression Atlas, because today that's an Afirma product because the variants that are curated and validated and reported off of the Xpression Atlas tests are all done as part of the Afirma testing portfolio. There, some of the variants actually can drive decisions around extent of surgery. Not everything that is a variant informs a treatment, of course.
Now that we can inform on all of these at the same time that we're moving 70% of the patients to a benign call, we're finding that our solution is resonating with more doctors out there and that more of the patients that they are testing, they are willing to send for Afirma testing because just our portfolio of answers has grown and the second generation test has certain subtleties of performance improvements over certain subtypes of cells. That's all going very well. The Xpression Atlas was launched last May. These new products that aren't answering a very specific clinical question sort of take some time to resonate. We came off of the early meetings this year, ACE and ENDO. I think for the first time, probably at ATA last year in the fall, we had the first-ever focus on targeted therapies in thyroid cancer.
You have to keep in mind that this whole field is still very young in thyroid cancer because we've had the silver bullet of radioactive iodine that has been predominantly the treatment of choice. These new therapies, though, that are pan-cancer therapies are being tested in areas of recurrence of disease where it looks like they're having quite a positive impact. Going forward, that standard of care could change. In terms of Percepta GSC and where we will head there in informing treatment decisions, it's really going to be a repeat of the strategy that was played out with Afirma.
It's taking the platform that we're running the Percepta GSC on, be able to curate the targets that are interested in targeted for lung cancer therapy and see how we might be able to package our solution in lung cancer to answer those questions at the same time that we're answering questions on diagnosis. It's really about shortening the timeframe, eliminating the follow-on procedures to get more samples, and being able to do it all quickly to get the patients on the best treatment that they can get on as fast as possible. Now that the Percepta is moved over to the next generation platform, we have the opportunity to start that journey as well.
Got it. Great. As far as the biopharma services milestone payments from J&J-
It looks like you got the Percepta milestone. What is the next milestone that you added to guidance? What is that related to, and what quarter do you expect that to hit the P&L?
Our milestones were driven across two products, the Percepta GSC, which you might imagine are the ones that have accelerated, given that we did accelerate that program when we announced the collaboration being a part of all of that. We have other milestones that relate to the advancement of the nasal test. One of those milestones, I believe, is what we're targeting to achieve this year. There will be-
Keith, that will be in the third quarter.
There will be additional milestones yet to come that will relate to the nasal program moving along.
Did I hear that correctly, Keith? That was the third quarter you expected?
Yeah. We expect to recognize $2 million in the third quarter from J&J. We do not currently expect to recognize any revenue in the fourth quarter, but we'll see how things develop.
We expect because these are milestone driven, this revenue in the biopharma side can be very lumpy and unpredictable. We'll be continuing to keep our focus on the product growth areas, the growth of our key clinical products, and then we'll try to give you some specifics like Keith just did on when these boluses of revenue could fall from services side.
I would add, just because you're sort of new to the story, we're recognizing $250,000 in service revenue from Loxo each quarter. We will expect to recognize that in Q3 and Q4 and next year as well. Just keeping that since we're talking about Johnson & Johnson separately, just don't leave that off the table either.
Right.
Understood. Understood.
Okay.
Yep. Thank you.
