Welcome to Natera's 2022 Second Quarter Financial Results Conference Call. At this time, all participants are in a listen-only mode. Following management’s prepared remarks, we will hold a Q&A session. As a reminder, this conference call is being recorded today, August 4, 2022. I would now like to turn the conference call over to Michael Brophy, Chief Financial Officer. Please go ahead.

Thanks, operator. Good afternoon. Thank you for joining our conference call to discuss the results of our second quarter of 2022. On the line, I'm joined by Steve Chapman, our CEO; and Solomon Moshkevich, General Manager of Oncology. Today's conference call is being broadcast live via webcast. We will be referring to a slide presentation that has been posted to investor.natera.com. A replay of the call will also be available at investor.natera.com. Starting on Slide 2. During the course of this conference call, we will make forward-looking statements regarding future events and our anticipated future performance, such as our operational and financial outlook and projections, our assumptions for that outlook, market size, partnerships, clinical studies, opportunities and strategies and expectations for various current and future products, including product capabilities, expected release dates, reimbursement coverage and related effects on our financial and operating results. We caution you that such statements reflect our best judgment based on factors currently known to us and that actual events or results could differ materially. Please refer to the documents we file from time to time with the SEC, including our most recent Form 10-K or 10-Q and the Form 8-K filed with today's press release. Those documents identify important risks and other factors that may cause our actual results to differ materially from those contained in or suggested by the forward-looking statements. Forward-looking statements made during the call are being made as of today, August 4, 2022. If this call is replayed or reviewed after today, the information presented during the call may not contain current or accurate information. Natera disclaims any obligation to update or revise any forward-looking statements. We will provide guidance on today's call, but we'll not provide any further guidance or updates on our performance during the quarter unless we do so in a public forum. We will quote a number of numeric or growth changes as we discuss our financial performance. And unless otherwise noted, each such reference represents a year-on-year comparison. And now I'd like to turn the call over to Steve.

Thanks, Mike. Let's get into Q2 highlights on Slide 3. As you can see from the press release, we had another strong quarter in Q2. Revenues grew approximately 40% over Q2 of last year. And we reached an incredible new milestone by processing 500,000 tests in a single quarter, growing more than 33% over Q2 of last year. We achieved this growth rate despite the fact that Q2 of last year had a large one-time benefit from a competitor exiting the NIPT business. We saw a strong continued sequential growth from organ health and oncology products, strong ASP gains in Signatera in NIPT, and we further strengthened our NIPT market position. We estimate our Panorama test now commands roughly 50% market share in this expanding market. This business momentum enables us to again raise our 2022 revenue guidance to $805 million to $825 million, an increase of $15 million at the midpoint. Pro forma for last year's one-time QIAGEN revenue of $28.6 million, this new range implies an annual revenue growth of 37%. Mike will cover this in detail later in the call, but our progress so far this year makes us even more confident on our path to cash flow breakeven in mid-2024. As good as the Q2 results were, they were negatively impacted by a timing difference of about $3 million worth of volumes that were accessioned in our lab but not reported out until early July. So we took the expenses on that testing in Q2, but we'll recognize the revenue and margin benefit in Q3. Therefore, we believe the printed results actually understate the momentum we think we are seeing in the business right now, and I think the rest of these highlights show that we are just getting started. We recently announced that we've been selected to participate in UnitedHealthcare's Preferred Laboratory Network after completing a rigorous application and review process for access, cost, data, quality and service. We were pleased to have the chance to undergo this rigorous review with the largest commercial insurer in the United States. We share UnitedHealthcare's commitment to driving improved patient access, affordability, outcomes and patient experience. Our organ health products were a significant contributor to both volume and revenue growth in the quarter. We were thrilled to see the publication of the Trifecta study in Transplantation, which is a leading journal in the transplant space. We think the Trifecta publication is a significant accomplishment. This is the largest prospective multisite fully biopsy-matched study that has ever been published in the space and highlighted the benefits of testing for both donor-derived cell-free DNA percent and quantity, which we provide with each Prospera result. I'll spend more time on this data in a few moments. In oncology, our progress for Signatera continues to exceed our expectations. We continue to reach a record number of Signatera tests performed in each sequential quarter with our commercial momentum remaining very strong, led by colorectal and immuno-oncology monitoring indications. In addition, we recently secured Medicare reimbursement for Signatera in muscle invasive bladder cancer. We think the clinical need for Signatera among muscle invasive bladder cancer patients is significant. And the peer-reviewed data we have presented thus far in bladder cancer is compelling. This is now the fourth time we have secured Medicare reimbursement and the first coverage expansion under the foundational LCD for MRD testing in solid tumors published in December of 2021. I think that demonstrates the breadth and depth of our data generation across tumor types and highlights our competitive advantage over others in the liquid biopsy space. We continue the drumbeat of presenting excellent data at ASCO in June with 11 circulating tumor DNA abstracts, including one oral and seven poster presentations. In addition, we plan to publish or submit many significant studies for Signatera in the next few months, including data in colorectal, gastroesophageal, pancreatic, breast, ovarian, melanoma and bladder cancers. Seven of these studies have more than 500 time points, making them some of the largest circulating tumor DNA studies to date and four are in new tumor types. I think the breadth and quality of the data opens up new indications where we can pursue reimbursement while also enhancing our credibility with community oncologists that treat many different types of cancer. Solomon will go into more detail on all of this later in the call. We were also thrilled to welcome Dr. Minetta Liu to Natera as Chief Medical Officer for Oncology. Dr. Liu previously served as Professor of Oncology and Chair of Research in the Department of Oncology at Mayo Clinic. Dr. Liu brings a wealth of expertise in how practicing oncologists can best apply Signatera and has already proven to be a fantastic addition to our team. Finally, we received another vote of confidence in the business from our Executive Chairman, Matt Rabinowitz, who announced an additional equity investment in Natera. This is on the heels of our lead independent director making an investment in Q1 and top management electing to forgo cash salaries this year in favor of stock compensation. We are all very excited about Natera's future, and I think the Q2 results demonstrate we are on the right track. Okay. Let's get into some of the business trends on the next slide. We processed a record 499,901 units in the quarter, one-third more than we processed just in Q2 of last year. As you can see from the volume progression on the chart, it was just recently that we surpassed 1 million tests for a full year in 2020. So to be at the 500,000 test level for a single quarter demonstrates the strong momentum in the business. We overcame our typical seasonality in the women's health business that we have historically seen in the second quarter, which is a function of existing accounts seeing fewer prenatal patients during Q2. In fact, this is only the second time in recent history that we've grown sequentially in Q2 versus Q1. New account starts were very strong, and we see an opportunity to further consolidate market share in women's health. Since the SMART trial was published in the spring, we are finding that data to be a significant competitive advantage in the field. We are off to a very strong start so far in Q3, and I think the raised guidance demonstrates our visibility and solid performance in the second half of this year. On the next slide, you can see the revenue growth was even stronger than the unit growth at 40%. That was driven by another step-up in NIPT ASPs in the quarter and continued strong sequential growth in our clinical ASPs for Signatera. As clinical Signatera volumes grow, the ASP progression is particularly impactful to the overall model. We described last quarter how clinical Signatera ASPs were in the 500s last year and stepped up to roughly $650 in Q1. We are now seeing the Signatera ASPs in the 700s for the first time, and we think there's room for more improvement in the second half of this year. This is being driven primarily by our mix of Medicare-reimbursed tests improving and an increasing fraction of our volume starting to come from the recurrence monitoring indication, which is reimbursed by Medicare at the ADLT rate of $3,900. So again, part of upward re-rating the guidance for the year is not only volumes but also these positive ASP trends. On the next slide is a bit more detail on our selection to UnitedHealthcare's Preferred Lab Network effective July 1. We have a long track record of innovation to improve the patient experience and deliver data that shows improved patient outcomes. So we are pleased to partner with United on this effort. United only includes a handful of U.S. labs in this network. And to be selective, labs must undergo a very rigorous, month-long quality audit that includes a detailed review of claims, processes and our internal software systems. This change means less administrative costs. And overall, we expect this agreement to be a positive for our women's health products. In women's health, we continue to benefit from further market penetration, driven by ACOG's average risk recommendation in NIPT from August of 2020. We estimate the NIPT market is roughly 50% penetrated. So there's still a large opportunity for growth, enabling us to help more patients and physicians. Our volume has also increased from competitive wins where we continue to differentiate ourselves with unique clinical features and strong data, combined with our focus on user experience. We now estimate we have roughly 50% of the overall NIPT market share. I think we're well positioned to continue to lead going forward given we're still publishing meaningful data and adding clinical features, while many competitors do not appear to be investing in clinical data generation or their NIPT business. One example of our investment in clinical data generation is the publication of the landmark SMART study in The Gray Journal, which validated the high clinical utility of 22q testing. The performance of our 22q test in the SMART trial was remarkable and may further differentiate our product going forward. Natera's 22q test is well positioned given the excellent sensitivity, specificity and PPV and because of our ability to assess the smaller 22q deletions that have historically been more difficult to detect and make up roughly 41% of the disease load. Test performance, breadth of disease load coverage and strong clinical data are important for physicians. Based on this quality of the SMART study, we are now even more optimistic that 22q deletion syndrome could be included positively in society guidelines in the near future. As 22q becomes more important as part of the decision of which NIPT laboratory to use, we see the benefit of choosing Natera increasing. Okay. Now in organ health, let's spend a bit more time on the Trifecta study recently published in Transplantation, which is a leading journal in the transplant space. The Trifecta study is the largest prospective multisite study of fully biopsy-matched patients for donor-derived cell-free DNA analysis conducted to date. Using a novel two-threshold algorithm incorporating both donor fraction and estimated amount of donor-derived cell-free DNA when assessing active rejection, the Prospera assay excelled at discriminating between active rejection and non-active rejection with an AUC of 0.88 versus molecular pathology. We are very proud of these results and the significant body of peer-reviewed evidence that we have generated now in the transplant space. We're continuing to perform very well, seeing record levels of test utilization in kidney, heart and lung donor-derived cell-free DNA testing. Shifting gears now to Renasight, which is our germline test for patients with chronic kidney disease. Chronic kidney disease affects roughly 37 million Americans, making it one of the single largest areas of health care today. Genetic testing for renal conditions using a broad test such as Renasight has demonstrated clinical utility. In fact, a recent study published in the New England Journal of Medicine showed that roughly 10% of chronic kidney disease patients have a genetic etiology. Results can inform targeted treatment and therapies, help avoid kidney biopsy, confirm or reclassify a clinical diagnosis, provide risk assessment to relatives, identify candidates for clinical trials and diagnose conditions that could benefit from additional medical referrals. A recent executive statement from the KDIGO guideline group has suggested that nephrologists should think genetically when evaluating chronic kidney disease patients. We completed enrollment in our RenaCARE real-world prospective multisite study in late July. Total enrollment in the study is now more than 1,700 patients across over 30 U.S. sites. To our knowledge, this is the only large-scale prospective multisite study looking at the clinical utility of performing routine genetic testing on chronic kidney disease patients. As a reminder, we started this study several years ago with the most prestigious academic centers in the field and partnered with Dr. Ali Gharavi, who's the Chief of the Division of Nephrology at Columbia University, as a principal investigator. We expect to submit this study for publication in late 2022. And we think it could have the potential to change guidelines around the management of patients with chronic kidney disease. We believe that CKD patients should be able to receive germline testing at the time of diagnosis. Given the number of patients diagnosed and living with CKD, the TAM for this opportunity is similar to that of hereditary cancer testing. Now I'd like to hand the call over to Solomon to cover our recent progress in oncology.

Thanks, Steve. The big news in oncology was MolDx's decision to cover Signatera for muscle invasive bladder cancer under its umbrella LCD, which we announced in July. This is our fourth coverage decision by Medicare for Signatera after early-stage colorectal cancer; then a follow-on extension for Stage IV oligometastatic colorectal cancer; then third, the pan-cancer immunotherapy monitoring; and now, bladder cancer. We expect the coding and pricing will be similar to CRC with coverage effect as of April 19. Based on the communications we've had from MolDx, we believe coverage will include the neoadjuvant, adjuvant and recurrence monitoring settings. With about 81,000 newly diagnosed cases per year, bladder cancer is the sixth most common cancer in the U.S., generally split into muscle invasive and non-muscle invasive. Signatera's coverage in muscle invasive disease on the right side of the page represents, we believe, about 35,000 new patients per year. With a median age of diagnosis at 73, we expect a heavier Medicare mix in this patient population than we see in CRC. Based on our anticipated testing schedule, which itself is based on current NCCN guidelines for imaging, we believe this implies approximately 400,000 Signatera tests per year at full adoption. As a reminder, to put this in perspective, that is more than 2x the size of the entire breast cancer gene expression testing market, which has been a very important area for diagnostics in the past. But most importantly, this will have a big impact on patients and patient care. To better understand the clinical utility of Signatera in this population, let's take a look at the patient journey. Today, guidelines recommend starting with a TURBT procedure, which stands for transurethral resection of the bladder tumor. This allows for pathological staging and assessment of the tumor's invasion into the surrounding muscle tissue. Once it's been diagnosed as muscle invasive, guidelines recommend neoadjuvant chemotherapy prior to cystectomy. This is where the first clinical conundrum presents itself as guidelines recommend monitoring for neoadjuvant treatment response and switching treatments if a patient fails to respond. However, it's reported that approximately 60% of patients do not respond to neoadjuvant chemotherapy with a lack of good biomarkers to assess that response. After surgery in the adjuvant setting, up to 2/3 of patients are cured by their surgery alone, while the other approximately 1/3 of patients will go on to experience distant recurrence. Here, the clinical challenge is whether to prescribe adjuvant systemic treatment, either chemotherapy for those patients who did not have neoadjuvant chemo or the new option of prescribing a year of immunotherapy as nivolumab was recently approved for use in patients at high risk of recurrence. Finally, in the surveillance setting, NCCN guidelines already recommend intensive monitoring as the scientific evidence is strong that early asymptomatic detection of recurrence leads to better survival. However, with the current monitoring tools, primarily imaging, it's reported that at least 50% of relapses are still detected too late. Signatera has been validated as a prognostic and predictive biomarker to help inform each of these challenges in conjunction with standard imaging and clinical assessment. There are two major peer-reviewed publications that supported Signatera's clinical validity in these settings. First, the 2019 Christensen paper in the Journal of Clinical Oncology, which followed 68 patients with regular testing, 656 time points in total, all the way from diagnosis through neoadjuvant therapy, surgery, then MRD assessment and recurrence monitoring. This study showed that serial Signatera testing could detect relapse with 100% sensitivity and 98% specificity with an average diagnostic lead time of about three months. Second, in the 2021 Powles paper in the journal Nature, we reported that Signatera could identify the 37% of patients who were MRD-positive after surgery and who benefited significantly from immunotherapy, while the other 63% of MIBC patients who are MRD-negative did not see any significant benefit from immunotherapy. Coming from the Phase III randomized IMvigor010 trial, this was the first demonstration that Signatera is predictive as well as prognostic. The strength of that data, together with the breadth of evidence in other cancer types, is what makes oncologists so enthusiastic about incorporating Signatera into their standard of care. We're now shifting our focus to commercialization to get this into the hands of as many bladder cancer patients as possible. We're already in an excellent position to commercialize with our existing infrastructure because Signatera is a pan-cancer platform. We will use the existing sales and marketing team focused on community and academic oncologists, the same user experience and customer support tools that have already been established and just simply continue scaling the existing Signatera lab since it's the same MRD product that we already offer for CRC and IO monitoring. With our strong commercial adoption and with every new covered indication, we create additional operating leverage and drive additional customer loyalty, further extending our first-mover advantage in this exciting field. After the bladder cancer announcement, we have been asked what is next in the clinical roadmap. We anticipate several important data sets to be published or submitted in the coming months in the areas of colorectal, gastroesophageal, pancreatic, breast, ovarian, melanoma and more. As Steve mentioned, seven of these papers have more than 500 time points and four of them are in tumor types where Natera has not yet published peer-reviewed data, making them substantial additions to our body of evidence. We expect those papers to be published in the second half of this year or in early 2023. And that will support our goals to expand insurance coverage to more patients. We also continue to grow and execute on our pipeline of prospective clinical trials, which are expected to deliver definitive practice-changing evidence over the coming years. In particular, I want to highlight here our continued momentum in colorectal cancer. Number one, we have submitted the CIRCULATE data from Japan for publication, which now includes 18 months of clinical follow-up versus the 12 months we presented earlier at ASCO GI. We expect that paper to be published soon. Number two, we're pleased to have enrolled the first patient into the new NCI-sponsored CIRCULATE-US trial. We think these two trials are an important part of our strategy to increase utilization and achieve our coverage goals. On the next slide, we're seeing early signs of enthusiasm from private payers. And we're hopeful that the NCCN Guidelines Committee for CRC, which meets in late August, may incorporate tumor-informed MRD into their guidelines. We believe a guidelines update is further supported by the recent data from Australia published in the New England Journal of Medicine, which showed that MRD-guided treatment of stage II colon cancer resulted in the same survival outcomes with approximately 2x less chemotherapy. Now I'd like to hand it over to Mike to cover the financials.

Great. Thanks, Solomon. The first slide is just the standard financial results for Q2. Steve covered the key trends on volumes and revenues. As Steve mentioned, revenues would have been roughly $3 million higher in the quarter if not for the timing difference between accessioning in the lab and reporting out the units, which is the event we need to accrue revenue. So that also artificially held down gross margins in the quarter, and I expect Q3 gross margins to be a little higher than usual as a result. Steve touched on the fact that new account starts were really strong in Q2. In women's health, we have a sustained track record of adding 250 to 300 new physician offices ordering per month on a base of approximately 20,000 customer accounts. We saw another quarter of good sequential progress on clinical Signatera ASPs. We've now moved from the ASPs in the 500s last year to roughly $650 in Q1 to now just above an estimated $700 in Q2 for the clinical ASPs. With clinical COGS now in the low 500s, we are still gross margin dilutive. But that progression is absolutely critical, given that the volumes continue to exceed our initial sales targets. We are armed with another coverage decision in our favor, and we are optimistic about starting to get some commercial coverage traction as Solomon described. I think that sets up for more ASP progress on Signatera in the second half of the year. NIPT ASPs were up sequentially again this quarter, and we think there's more room for progress on women's health ASPs in the second half of the year. The balance sheet remains strong. We used substantially less cash in Q2 as compared to Q1 this year. We expect quarterly cash usage to continue to drop meaningfully in the second half as revenues grow and expenses remain stable. In addition to that progression, we estimate that we have about $30 million in receivables on accrued units that we expect to catch up on in the second half of the year. The catch-up is driven by a software update that caused us to hold a portion of our claims this spring and our ramping up of operations that are particular from Medicare reimbursement for Signatera. Spending a bit more time on the cash flow breakeven on the next slide. Last quarter, we went into some detail laying out a longer-range model with our expected progression. I won't repeat all of that here, but the first half of 2022 has reinforced for us that getting to cash flow breakeven is not going to require drastic cuts or fundamental changes to the business model. Today, we've already established ourselves as the market leader in multiple large and growing markets. We've got a significant lead in generating data that we think could take years to close even if we stop clinical trials now. We front-loaded our investment in commercial infrastructure, and we are reaping the benefits as the volumes come in and revenues continue to grow quickly. Because of all that, we can generate significant returns on invested capital by porting these established products onto lower-cost sequencers and scaling our cost-efficient Austin lab. So just that base case drives clear visibility to cash flow breakeven. Based on the results we've seen so far this year, we now think we can get to a cash flow-breakeven quarter by mid-2024. On top of that base case, I think we have a number of potentially meaningful catalysts that we think can be achieved in the near term, as you can see on the right-hand side of the page. We think it's likely one or more of these could be achieved as early as this year. Any one of these catalysts would represent another step function change for the Company, and we've spent a lot of time describing why we are in a great position to achieve each of them. Okay. Good. Let's get to the next slide and the updated guidance for the year. Steve touched on the re-rate of the revenue guidance range for the rest of the year. As you can see on the slide, this new guide represents a major step up from our initial guide in March and reflects the strength we are seeing in both ASPs and volumes across the Company. We are holding cash burn, margins and expenses stable to the prior guide for now, which represents some caution on the working capital elements we described earlier, expected continued scale in the women's health products and a recognition that the Signatera clinical unit economics, while improving, are still in a phase where they are dilutive to gross margins for the time being. Finally, we expect to publish our inaugural ESG report in the near term, including our 2025 sustainability goals, which we are very excited about. So we're very pleased to be able to share these results with you today. And now let me hand the call over to the operator for questions.

Our first question comes from Tejas Savant with Morgan Stanley.

Congrats on a strong quarter here. My first question is on reproductive health. Steve, can you talk a little bit about the opportunities for share gain that you alluded to here, particularly given some of the competitors going through internal restructurings? How much of that is playing into your outlook increase? And then as we think about the Roe versus Wade decision, is there a possibility here of microdels getting into guidelines sooner off that? And how should we think about the revenue implications? Is that sort of a '23 situation?

Yes. Thanks for the question. So I think on the share gains, we think it comes down to a lot of things. I think largely that we generated significantly more clinical data supporting the validation and the performance of Panorama than any other NIPT company. And in addition, there's about nine points of clinical differentiation where we offer things that others simply can't do. So I think it's largely those two things, combined with our focus on user experience that are driving our share gains. Of course, as others pull back their investments both in their commercial infrastructure and also in R&D, I think that does benefit us. But largely, I think we're benefiting from the data and the clinical differentiation. On the 22q side, we've talked a little bit more in this earnings call about the possibility of society guidelines being updated in the near future. There's a very strong clinical utility resulting from doing prenatal testing for the 22q deletion and that's outlined in the SMART study, which was the largest prospective trial that's ever been done in the space that was published in January of this year. So we do think that there's a likelihood, a possibility that society guidelines change in the near future and include 22q as part of routine prenatal screening. And I'd just say that we feel more confident now than we have in the past that those guidelines are going to change.

Our next question comes from Dave Delahunt with Goldman Sachs.

Guys, congrats on the strong quarter. You see the ASPs going up. Could you double-click on that and give us a little bit more color on what's going into both NIPT ASPs going up as well as Signatera getting up into the 700s now?

Yes, Mike, do you want to take that?

Thank you for the question, Dave. It's great to talk with you. As expected, the Signatera average selling price is aligning with our expectations from earlier this year. We are seeing an increase in our Medicare mix and the number of reimbursed chemotypes, and as we continue with the launch, more patients are falling into these reimbursed categories. This is a natural progression for Signatera, which we are closely monitoring as the demand increases. Regarding the NIPT side, we anticipate similar improvements. Many state plans have historically not covered or priced NIPT, but we are gradually overcoming administrative barriers and seeing new coverage policies implemented. These factors are driving our progress.

Our next question comes from Catherine Schulte with Baird.

What are you expecting in terms of muscle invasive bladder and any contribution to guidance there? Also, I think you've seen stronger adoption in the older patient population for colorectal cancer. Given the older SKU for bladder, do you anticipate that being a limiting factor for adoption?

Yes. Solomon, do you want to take that?

Sure. I didn’t quite hear the very first part of your question, Cathy. Were you asking about our expectations for commercial adoption in bladder cancer? I’ll address the second part. With the median age of diagnosis at 73, we do expect a larger Medicare mix, which will positively impact ASPs. We don’t anticipate that weighing down the adoption curve. The enthusiasm and receptiveness we’ve seen from GU oncologists has been significant, especially considering the unmet needs they have in managing bladder cancer patients.

Yes. Let me just add on commercial adoption, I'll say we're already seeing a nice increase in the utilization in muscle invasive bladder post-some of these publications coming out. And post the coverage decision, there's been, I think, a lot of positive buzz. So I think we're feeling good about it. I think when you look at the overall TAM, it's about maybe 1/3 to 1/2 of what we had announced previously for colorectal, so that's potentially a good benchmark. But the other thing that I think is really unique here is that there's very limited data, I think, from competitors in this sector in muscle invasive bladder. And I think that's an opportunity for us to really kind of, on the long term, have an outsized share of this particular segment of the market, which I think is a great benefit.

Our next question comes from Max Masucci with Cowen.

Just the first one, if you look at Slide 20 in the deck, it highlights the mid-2024 target for quarterly cash flow breakeven. In the prior Q1 slide deck, it suggested that $1.3 billion to $1.5 billion revenue run rate and 55% gross margins would get you there to breakeven. So if we just look at that mid-2024 target on Slide 20, it seems to imply that $1.3 billion to $1.5 billion in revenues could be a reasonable target for 2024. Just looking at consensus, it's just north of $1.2 billion. So it's more of a broad question of just about how we should think about that, bridging those two numbers and the confidence that we can have in our modeling for the growth segments?

Yes, thank you for the question, Matt. It's great to talk with you. In terms of our cash flow breakeven threshold, it's important to note that this is different from full year revenue targets. We often get inquiries about which quarter we expect to reach that threshold. I believe our confidence in achieving this has grown as the year progresses, supported by the ongoing commercial success and progress across our business, which allows us to be more precise about the timing. However, this shouldn't imply any inconsistency between the previous numbers and our model; it's simply a matter of specifying a particular quarter.

Thank you. Our next question comes from Puneet Souda with Leerink.

So first one is really around NCCN. Can you just provide any updates there in terms of Signatera? And any studies or things that you have submitted or anything that you expect here in the second half?

Yes, I'll take that. And Solomon, maybe you may want to add something additional. So I think we're feeling positive. Although we don't control the guidelines, I still think that there's some good discussion happening with KOLs that we're feeling positive about, both from the data that we've generated and also from the data from the DYNAMIC trial that was presented previously. So I think that there is a good opportunity for guidelines to potentially change in the summer or later in the year, like the December time frame. The biggest contribution that we'll be making to that will be the publication of the CIRCULATE-Japan study. And that paper is now in submission as we said it would be. And there is a possibility it could be published sometime this summer or in the early fall. And one of the key updates is that the follow-up for that study has now been extended to 18 months. And I think that just makes the paper even stronger than it was before and I think well positions that to really drive guidelines if they haven't changed this summer based on the existing data. Solomon, feel free to add to that if you'd like.

Yes. I'll just add two things. First, we do not think that publication of the GALAXY data in August is gating for a change in the guidelines, though we've done everything we can to accelerate that. And again, the reason we don't think it's gating is just because there has been so much other data now published and presented in the field that has really impacted how leading GI oncologists think about utility here. And as Steve mentioned, the DYNAMIC trial from Australia was a welcome addition to the overall body of evidence supporting ctDNA.

Our next question comes from Julia Qin with JPMorgan.

Can you hear me now?

Yes.

All right. Could you give us an update on the current mix between first-year patients and recurring patients? And in light of the expanded coverage, what kind of ASP trajectory are you expecting for Signatera over the next few years?

Sure. Let me address the first part. Then, Mike, you can discuss the ASP trajectory. In the long term, there are significantly more patients living with cancer compared to those diagnosed each year. Therefore, we anticipate a notable shift towards recurrence monitoring in the future. Currently, the demand for our test remains high, with a considerable influx of new patients using it for the first time. As our commercial and clinical teams engage with more doctors, we are seeing a large number of patients at their initial time point. Over the past two years, we have noticed a gradual shift in volume towards the recurrence monitoring and longitudinal tracking segment, which aligns with expectations. However, this dynamic is affected by the substantial number of new patients continuously entering the system. Mike, would you like to add more about the ASP?

Yes. I mean, I think those drivers actually influence ASP quite a lot. I think in summary, we think that the current ASP is quite immature for Signatera, and it's really a function of volumes expanding in these reimbursed populations, having more of these populations covered by Medicare, where we feel like we can really make a huge difference to the care in these patients. The clinical utility that we've demonstrated, I think, in some of the data that we published, particularly the prospective data in colorectal cancer, we think is really compelling. And obviously, that would then direct guidelines, which, of course, guidelines would then drive a broader commercial coverage. All those things are areas that we expect to happen over the next few years in Signatera, which would drive ASPs significantly higher and make this business something that works for everyone.

Our next question comes from Mark Massaro with BTIG.

This is Vivian on for Mark. So could you share with us at a high level what some of the key milestones or catalysts will be for your early detection program? Could you also share any learnings you may have gleaned from potential discussions with the FDA as it relates to clinical trial development or size of patient enrollment?

Yes. Thanks for the question. So as we said before, on early cancer detection, which is a priority for us, what we're doing is we're leveraging the data that we have on early-stage tumor exomes, and we've used that to generate a proprietary targeted panel of DNA mutations. We're combining that with methylation signatures, both available from public databases but also that we've developed ourselves and that we've licensed from our partnership with Aarhus University. So we're taking the DNA combined with methylation and we plan to run that and generate some data looking at the performance of the test. The initial performance looks good, and that's prompted us, obviously, to continue with the work. But we plan on having a kind of more significant readout, I would say, later in '22 at some point in kind of the first half of '23 roughly. The biggest milestones in front of us are getting feedback from the FDA. In fact, we've already done our pre-submission to discuss the clinical trial that we are participating in. And we're looking forward to that meeting, which will be coming up in the next couple of months. And then post that, we'll be understanding their feedback, adapting our trial strategy if need be and then generating more significant proof-of-concept data, as I mentioned in the next kind of year or so.

Our next question comes from Alex Nowak with Craig-Hallum.

This is Connor on for Alex. I guess, first, I was hoping on some color around the competitive environment in MRD test. As I'm sure you all know, Guardant Health got their test covered. But I mean, do you expect some of these tests to be solely used for adjuvant decision-making and others used for recurrence monitoring? Just some thoughts there would be helpful.

Yes. Thanks. So from a competitor standpoint, I think we think that we're doing exceptionally well. I think in physicians' minds, we're seeing that the tumor-informed approach is the winner. We think we have the vast majority of the market share at this point, and we're in a very good position. Most of that is driven by the breadth and depth and quality of our peer-reviewed data. We think physicians will want to use the same test for the MRD time point and adjuvant decision-making as they will for recurrence monitoring. And when you look at our local coverage decision from Medicare based on the data that we've generated and the peer-reviewed evidence that we've had, we've received coverage for both the MRD time point adjuvant decision-making in addition to longitudinal monitoring or recurrence monitoring. And we think that that's really important long-term. Similar, when you look at muscle invasive bladder, we've now received coverage for neoadjuvant for MRD adjuvant and for longitudinal recurrence monitoring. Again, I think just showing that we have super high-quality data and the breadth of our data is outside of just one narrow indication.

Our next question comes from Mason Carrico with Stephens.

Sorry about that. Maybe to hit on Prospera kidney for a minute. Could you update us on penetration in the kidney centers? How many centers are you receiving orders from? And then thinking about the components of growth there, how much is coming from untouched greenfield opportunity? And are you guys taking share there as well?

Thank you for your question. From a volume and growth perspective, we are performing well. We are experiencing an increase in volume and achieving record numbers each quarter. Physicians are providing very positive feedback following the publication of the Trifecta study, which is the largest multisite prospective fully biopsy-matched study conducted to date. We continue to receive excellent responses and believe we are in a strong position. We are currently collaborating with a significant number of transplant centers, previously estimated at around 50%, and that number is steadily rising. In terms of market penetration, we believe approximately 10% of the overall market is currently penetrated, meaning that the majority of patients are still not being monitored with donor-derived cell-free DNA. We see this as a major opportunity. While some centers have yet to adopt donor-derived cell-free DNA, others are using it selectively. As more data is produced and physicians integrate donor-derived testing more regularly into their practices, there is clearly substantial potential to assist patients.

Thank you. This concludes the Q&A session. Thank you for participating. This concludes today's conference call. You may now disconnect.
